Are you working as a freelancer? Whether you're a writer or a web designer, you've likely put a lot of time and energy into your freelance business. 

For some, it’s a side hustle, a way to get some extra cash to supplement their day job. For others, a freelance business is a way to build a brand and use their skills to earn a regular living.

Getting paid as a freelancer means creating and sending invoices to your clients. But what should these invoices include?

In this post, we’ll explain the invoicing process for freelancers. We’ll also cover how invoice software and invoicing apps can improve the efficiency and success of your freelance business.

Key takeaways

Ensure your invoice has all essential information for clarity.

Streamline the process with invoicing software to track payments.

Communicate payment terms upfront to avoid issues.

Why should freelancers use an invoice?

As a freelancer, invoicing is an indispensable part of the payment process. Unless your clients pay upfront, it’s best to use an invoice to communicate that you expect payment from your clients.

Using an invoice ensures that you receive payment promptly for your services and helps you stay organized when juggling multiple projects. Invoices are particularly important if you’re charging different rates for various types of services.

For example, you may be charging an hourly rate for your services for one client but working at a flat rate for other projects. Maintaining an invoicing system can streamline your billing process so there’s never any confusion about payment.

What's the difference between an invoice and a bill?

Both an invoice and a bill communicate the expectation for payment. The critical difference, however, is in the level of detail.

An invoice contains essential data that the customer must review and approve before rendering payment to the freelancer. This information will include details regarding the type of service, the requested amount, and the conditions for payment.

An invoice should also contain an invoice number for accounting purposes.

A bill, on the other hand, contains none of these details. Instead, it simply describes the services and expected payment.

When to send a freelance invoice?

There’s no hard and fast rule about when to send an invoice to a client. However, in general, it’s best to send your invoice after you complete the work. That way, you can ensure the client is satisfied with the work you’ve provided. Invoicing at the end of a project may also serve to foster trust between you and your client.

There may be times you wish to issue an invoice at the start of your project. For instance, if you’re working on a larger project, you may want to invoice the client to request partial payment upfront – known as progress invoicing. That way, your invoice might act as a sort of “security deposit,” ensuring that you receive at least some payment upfront. You can then request the remainder once you complete the project.

Of course, an app can make this entire process easier than ever before. An app can be one of the best invoicing tools you can use. It can ensure that you get paid on time while improving cash flow.

An app can also direct traffic to your website. Lastly, using apps to create and send invoices can ensure that businesses maintain a solid financial relationship.

What should I include in my freelancer invoice?

While we recommend that you customize and brand your freelancer invoices, there is information that all businesses should include on their invoices. For more detailed information on how to create an invoice, check out this article.

Your invoice should include a professional-looking header that communicates the name of your freelance business -- or at least your name if you don’t have an actual business name. If you have a logo, all the better!

Essential invoice details to include

You’ll also want to include the client’s name, contact information, an invoice number, the date the invoice was prepared, and a description of services. Also be sure to include the amount due, the payment terms, and the due date.

We recommend giving your customers plenty of payment options. Clearly specify how you would like your client to pay for your work. How do you accept payments? Do you accept credit card payments? Paypal? To whom should your client write a check?

Be sure to include a thank you

Conclude the invoice with a small note of gratitude to your customers, thanking them for using your freelancing business and encouraging them to return in the future. This may also encourage the client to tell others about the positive experience they had in working with you.

Create a custom freelance invoice template

Create a custom freelance invoice template
You can build a custom freelance invoice template using an app and then keep this information on file when sending invoices to your clients. Even with online invoicing, your invoice template should generally have the following details to your customers.

Invoice software for freelancers

Does this sound like a lot? It can be! Once your freelance business takes off, it can be hard to juggle contracts, invoices, cash flow, and still have time to focus on your work.

When you're self-employed, you may discover that your business needs invoice software to give you a much-needed boost.

BILL Accounts Receivable enables you to generate invoice templates and send invoices right from your phone or mobile device. You can also use our invoice generator and other online tools to create a custom invoice that can keep your head above water when the workload starts to rise.

One of the greatest advantages of using invoicing software is that it streamlines the entire process. These innovative invoicing tools will allow you to generate an invoice faster. You'll also be able to accept payments electronically.

An invoicing app can even keep track of your invoices and cash flow -- it’s almost like having your own accountant at your fingertips!

Freelancer invoicing tips

If you’re just starting out, the invoicing process may seem a bit daunting. Here are a few tips that can make the process a little easier -- or at least boost your confidence when it comes to sending invoices!

Be detailed

It’s always better to include too much detail than too little. A detailed invoice makes it clear what you expect the client to pay.

Set deadlines

The length of your deadline is up to you, but it’s generally a smart move to set a payment deadline so that you don’t get lost in the shuffle.

Keeping up with regular deadlines can ensure that your freelance business has a smooth cash flow and that you stay organized, as well.

Be personal

Broadcasting your personal brand doesn’t mean that you can’t be personal. Think of an invoice as a very specific type of letter. Sure, you’re asking for money, but that doesn’t mean you can’t warmly communicate your thanks and appreciation for your client’s patronage.

This personal touch can set you apart. It may make your client more willing to return to you in the future or to recommend your services to their friends and associates.

Use an app and freelancer invoice template

In the digital age, many businesses rely on innovative technology such as accounting software and invoice apps. Freelancers can enhance their business by using an app-based invoicing system so that their clients can view invoices and make payments directly through the app.

In addition, by creating a custom freelance invoice template, you’ll save yourself time and always look great with professional-looking invoices.

Communicate expectations before the invoice

Before you enter into a business relationship with a client, you should clearly communicate your expectations, especially regarding the payment process. Due dates, late fees, and payment methods should be covered upfront so that the invoice serves as a reminder of what you’ve already discussed.

Frequently Asked Questions

Do you have more questions? Here are some of the most common questions we hear regarding the invoicing process.

Is an invoice legally binding?

Technically, an invoice only communicates your request for payment. An invoice cannot be used on its own to prove that both parties have entered into a contractual arrangement. This means that an invoice cannot legally prove that a client owes money to a freelancer.

Only business contracts can serve as legal documents. Invoices can be disputed

How do I set a payment deadline?

The length of your payment deadline is entirely up to you. In fact, no deadline is even necessary, though establishing a payment deadline can ensure that you receive payment in a timely manner.

It's common to set a deadline of 30 days for the client to make a payment, though you can also extend this deadline to 60 or 90 days if you wish.

What happens if a client doesn't pay me?

If you don't get paid for your hard work, your first step should be to contact the client directly to determine which parts of the invoice are in dispute.

Sometimes, these issues can be resolved through simple discussion. Your client may have been waiting until they received payment reminders. Otherwise, you may have to take legal action against this client in order to receive payment.

Can I create two invoices for the same job?

While you can't bill the client twice for the same job, it's possible to create two invoices for the same job. This way, you can request partial payment for a portion of the project, then request full payment once the project is complete.

Ordinarily, you'll want to send an invoice upon completion, but invoicing upfront can be a way to form a relationship with a new client by establishing milestone payments.

BILL Spend & Expense
Best for AI expense automation
4.5 on G2
  • Smart corporate cards with real-time tracking, flexible limits, and instant visibility into every transaction across your team [1]
  • Unlimited free virtual cards with unique numbers for each vendor or subscription—freeze, delete, or set custom limits instantly to prevent overcharges and reduce fraud risk [5]
  • AI-powered auto-categorization and receipt matching that connects card transactions and expenses into a single reconciliation workflow [1]
  • Customizable budgets with spend controls based on merchant, amount, receipt requirements, and configurable approval workflows [3]
  • Auto-freeze on cards with incomplete transactions, ensuring receipts and documentation are captured before additional spend is approved [1]
  • Up to 7x points on restaurants, 5x on hotels, 2x on recurring software, and 1.5x on all other purchases (rates shown are for weekly or daily billing cycle; rates vary by billing frequency) [2]
  • Two-way sync with QuickBooks, NetSuite, Sage Intacct, Xero, and Microsoft Dynamics; additional integrations with Acumatica, Slack, and HRIS platforms [1]
  • Pro: $0/user/month with all features included—no paid tier to unlock [4]
  • Pro: Merchant controls and auto-freeze cards at no extra cost [1]
  • Pro: Credit lines that don't fluctuate daily based on bank balance [4]
  • Pro: All ERP integrations (NetSuite, Sage Intacct, Xero) included free [1]
  • Con: 12-month holding period before rewards can be redeemed [2]
  • Con: Category reward multipliers cap at $5,000/month per category [2]
  • Con: Less established in global, enterprise-scale expense programs with multi-country regulatory requirements

BILL Spend & Expense pairs corporate cards with AI-powered expense management and budget controls in a single platform at no cost—teams aren't paying per user or upgrading to unlock features that competitors gate behind paid tiers.

Merchant-level spend controls and auto-freeze on incomplete transactions give admins granular oversight without manual policing, and two-way ERP integrations are included free where Ramp and Brex charge for NetSuite and Sage Intacct access. The main trade-off is an initial 12-month rewards holding period before accumulated points can be redeemed. [1][2][3][4]

Commonly compared to: Ramp and Brex (for card-first expense management), and SAP Concur (for enterprise expense programs).

  • AI-powered receipt capture via ExpenseIt on the SAP Concur mobile app, with smart matching that combines credit card charges and e-receipts into expense reports automatically [7]
  • Configurable approval workflows with built-in audit rules that flag policy exceptions, plus optional Intelligent Audit and Verify add-ons for automated compliance checks [6][7]
  • Modular product suite: Concur Expense, Concur Travel, and Concur Invoice are separate products that can be purchased individually or together, so organizations can start with expense management and add capabilities over time [6]
  • Bank card feed integrations that import corporate card transactions directly into expense reports for automatic reconciliation [6]
  • Joule, SAP's AI assistant, for expense report review, spend analysis, and cost estimation [6]
  • Budget tracking and monitoring tools that give finance teams visibility into spend against departmental or project-level budgets [6]
  • Support for global operations with multi-currency expense reporting and country-specific tax and regulatory compliance tools [6]
  • Pro: 300+ pre-built integrations including native SAP ERP sync [7][8]
  • Pro: Global coverage with multi-currency and regulatory compliance tools [6]
  • Pro: Modular—add travel or invoice management without switching platforms [6]
  • Pro: AI-powered receipt capture and smart matching via ExpenseIt [7]
  • Con: Quote-based pricing; no published rates on the website [6]
  • Con: No corporate card offering; relies on bank card feed integrations [6]
  • Con: Implementation can be complex for smaller organizations [6]
  • Con: Live support requires purchasing the User Support Desk service [6]

SAP Concur is the incumbent in expense management software, with the largest partner ecosystem and broadest global footprint on this list. Its modular approach gives large organizations flexibility to start with expense management and layer on travel or invoice capabilities independently.

The trade-off is complexity—pricing is opaque, there's no corporate card offering, and smaller teams may find the platform more than they need. Organizations already in the SAP ecosystem will get the most value from native S/4HANA integration. [6][7][8]

Commonly compared to: BILL (for SMB expense management), and Coupa (for enterprise spend management).

  • Best for: Mid-market and enterprise organizations that need a globally scalable expense management platform with configurable compliance tools and a large partner ecosystem. [6][7][8]
  • Highlights: AI-powered receipt capture via ExpenseIt, configurable approval workflows with built-in audit rules, optional Intelligent Audit and Verify add-ons for automated compliance checks, 300+ app integrations, and native SAP ERP sync. [6][7][8]
  • Ideal if you need: An expense platform that integrates natively with SAP S/4HANA or other enterprise ERPs, with the flexibility to add modules like Concur Travel or Concur Invoice over time. [6][7]

4.8 on G2
  • Corporate cards with customizable spend controls by merchant, category, employee, or department, plus unlimited virtual and physical cards [9][10]
  • AI-powered receipt matching, transaction coding, and memo suggestions that auto-populate as soon as a card is swiped [9]
  • Policy agent that reviews every expense against company policy, auto-approves compliant transactions, and escalates only exceptions with full audit trail [9]
  • Expense submission via SMS, Slack, or Microsoft Teams in addition to web and mobile app [9]
  • Reimbursements for out-of-pocket expenses paid to employees' bank accounts in 1–2 business days [9]
  • Real-time spend reporting with custom dashboards, natural-language queries, and proactive overspend alerts [9]
  • Broader spend platform that includes AP automation, procurement, vendor management, and treasury alongside expense management [9]
  • Pro: Free plan includes corporate cards, expenses, and bill pay [11]
  • Pro: AI policy agent reviews 100% of expenses automatically [9]
  • Pro: Submit expenses via SMS, Slack, or Teams—no app required [9]
  • Pro: Broader spend platform covers AP, procurement, and vendor management [9]
  • Con: Budget tracking requires Ramp Plus at $15/user/month [11]
  • Con: NetSuite, Sage Intacct, and Dynamics integrations require a paid plan [11]
  • Con: HRIS syncs and auto-lock cards require a paid plan [11]
  • Con: Credit limits fluctuate daily based on connected bank balance [12]

Ramp's strength is breadth—it's not just an expense tool but a full spend management platform that includes AP automation, procurement, and vendor management alongside expenses. The AI policy agent is a differentiator, reviewing every transaction against company rules rather than relying on manual manager approvals.

The trade-off is that several features mid-market teams rely on—budget tracking, ERP integrations beyond QuickBooks and Xero, and HRIS syncs—require upgrading to Ramp Plus at $15/user/month plus a platform fee. [9][11]

Commonly compared to: Brex and BILL (for corporate cards and expense management), and SAP Concur (for enterprise expense programs).

  • Best for: Fast-growing companies that want corporate cards, expense management, and accounts payable on a single platform with AI-powered automation. [9][10]
  • Highlights: Corporate cards with built-in spend controls, AI-powered receipt matching and expense coding, a policy agent that reviews 100% of expenses and flags only exceptions, and submission via SMS, Slack, or Microsoft Teams. [9][10]
  • Ideal if you need: A card-first platform where expense management is one part of a larger system that also covers AP, procurement, and vendor management. [9]

  • Corporate cards with customizable spend limits by role, department, or category, plus auto-approve for in-policy expenses and auto-decline for out-of-policy spend [13][14]
  • AI-powered expense reviews that auto-approve compliant transactions and surface only exceptions for human review, with clear visibility into why a transaction is flagged [13]
  • Auto-generated receipts and memos with OCR that matches receipts in any language or currency, plus automatic GL coding by department, project, and entity [13]
  • Live Budgets that let department heads set top-level budgets, provision spend to individuals or teams, and track usage in real time with anomaly detection [13]
  • Global reimbursements in 70+ countries in employees' local currency, with subsidiaries able to issue reimbursements from local bank accounts [13]
  • Expense submission and approval via Slack and WhatsApp, with in-app commenting on individual transactions [13]
  • Broader financial platform that includes bill pay, business banking with up to 3.68% yield, and treasury alongside expense management [14]
  • Pro: Free plan includes corporate cards, expenses, bill pay, and travel [15]
  • Pro: AI expense reviews with 99% average policy compliance rate [14]
  • Pro: Global reimbursements in 70+ countries in local currency [13]
  • Pro: Live Budgets with real-time tracking and anomaly detection [13]
  • Con: Live Budgets require Premium at $12/user/month [15]
  • Con: HRIS syncs and customizable ERP integrations require a paid plan [15]
  • Con: Credit limits fluctuate daily based on connected bank balance [16]
  • Con: Multiple expense policies and dynamic review chains require Premium [15]

Brex positions itself as a full financial stack for startups—cards, expenses, banking, and treasury in one platform. The AI expense reviews and 99% average compliance rate (per Brex's internal metrics) are notable, and the global reimbursement coverage across 70+ countries is broader than most competitors on this list.

Like Ramp, Brex gates budget management and HRIS integrations behind a paid tier, and credit limits fluctuate daily based on your bank balance. Teams that need predictable spending power or are past the startup stage may find the pricing structure adds up. [13][14][15]

Commonly compared to: Ramp and BILL (for corporate cards and expense management), and SAP Concur (for enterprise expense programs).

  • Best for: Startups and high-growth companies that want a global financial platform covering corporate cards, expense management, bill pay, and business banking. [13][14]
  • Highlights: AI-powered expense reviews that auto-approve compliant transactions, corporate cards with built-in policy controls, Live Budgets for real-time tracking, global reimbursements in 70+ countries, and OCR receipt matching in any language or currency. [13][14]
  • Ideal if you need: A financial platform built for startups that includes expense management as part of a broader stack with banking, treasury, and AP. [13][14]

Expensify
Best for simple reimbursements
4.5 on G2
  • SmartScan receipt capture by photo, email forwarding (receipts@expensify.com), or text message; auto-extracts transaction details and categorizes expenses [17]
  • Bring-your-own-card support: link existing corporate cards from 10,000+ banks globally for automatic reconciliation without switching card providers [17]
  • Expensify Visa Commercial Card with cash back on US purchases; cash back first offsets the Expensify subscription cost, then flows to the company's bank account [17]
  • Concierge AI for automated expense categorization, policy violation flagging, rule enforcement, and error reduction [17]
  • Global reimbursements for employees and independent contractors in their local currency [17]
  • Chat-based collaboration directly on individual expenses to resolve questions in real time rather than through email follow-ups [17]
  • 45+ integrations including QuickBooks, NetSuite, Sage Intacct, Xero, Workday, and Gusto [17]
  • Pro: Bring-your-own-card from 10,000+ banks globally [17]
  • Pro: Expensify Card cash back can offset the subscription cost [17]
  • Pro: SmartScan receipt capture by photo, email, or text message [17]
  • Pro: 45+ integrations including major ERPs and payroll systems [17]
  • Con: No free plan; starts at $5/user/month [18]
  • Con: Pricing structure varies by card spend volume [18]
  • Con: Budget management, advanced approvals, and expense policies require Collect or Control plans [17]
  • Con: No department-level budget management on par with card-first platforms

Expensify's strength is accessibility—it has the lowest barrier to entry for teams that just need to start tracking expenses and submitting receipts. The bring-your-own-card support from 10,000+ banks means companies don't have to switch card providers, and the SmartScan receipt capture (by photo, email, or text) is one of the more flexible input methods on this list.

The trade-off is that several features mid-market teams expect—budget management, advanced approvals, and expense policies—require upgrading to the Collect or Control plans, and spend controls are primarily limited to the Expensify Card rather than extending across all connected cards. [17][18]

Commonly compared to: Zoho Expense (for budget-friendly expense management), and BILL and Ramp (for integrated cards and expenses).

  • Best for: Small and midsize businesses that want a mobile-first expense management tool with flexible card options, including the ability to link existing corporate cards from 10,000+ banks. [17]
  • Highlights: SmartScan receipt capture by photo, email, or text message; bring-your-own-card support from 10,000+ banks globally; Expensify Visa Commercial Card with cash back that offsets subscription costs; and Concierge AI for automated categorization and policy enforcement. [17]
  • Ideal if you need: A lower-cost entry point for expense management where employees can start submitting receipts immediately without switching corporate card providers. [17]

Zoho Expense

4.5 on G2
  • Autoscan receipt capture with OCR that auto-categorizes and itemizes each expense, plus the ability to split or tag expenses across departments, projects, or cost centers [19][20]
  • Automated per diem calculations with pre-defined rules based on country, location, and trip details for regional compliance [20]
  • Corporate card management with real-time feeds that automatically match transactions to uploaded receipts for faster reconciliation [20]
  • Mileage tracking with four input methods across Android, iPhone, and Apple Watch [20]
  • Configurable approval workflows, expense policies, and audit rules with detailed audit trails for compliance [19][20]
  • Custom modules, workflow automation, webhooks, and configurable UI elements for businesses that need tailored expense processes [19]
  • Active-user pricing model: only employees who actually create expenses are charged, so admins and approvers who don't submit reports are free [21]
  • Pro: Free plan available for up to 3 users with core expense tracking [21]
  • Pro: Active-user pricing—admins and approvers aren't charged [21]
  • Pro: Automated per diem calculations by country and location [20]
  • Pro: Deep customization with custom modules and workflow automation [19]
  • Con: Corporate card feeds and multi-level approvals require Standard plan [21]
  • Con: Deepest value requires the broader Zoho ecosystem (Books, People, CRM) [19]
  • Con: No corporate card offering; relies on connecting existing cards [20]
  • Con: Travel booking, per diem, and live budgets require Premium plan [21]

Zoho Expense offers unusually deep customization at a low price point—custom modules, workflow automation, webhooks, and configurable UI elements that most competitors don't expose. The active-user pricing model is genuinely cost-effective for companies where only a portion of employees submit expenses regularly.

The trade-off is that there's no corporate card offering—you'll need to connect your existing cards—and the platform delivers its deepest value when used alongside other Zoho products like Zoho Books and Zoho People. [19][20][21]

Commonly compared to: Expensify (for budget-friendly expense management), and SAP Concur (for global compliance and customization).

  • Best for: Small and midsize businesses that want an affordable, highly customizable expense management platform with strong global compliance features and active-user pricing. [19][20][21]
  • Highlights: Autoscan receipt capture with OCR, automated per diem calculations by country and location, corporate card reconciliation with real-time feeds, mileage tracking across multiple input methods, and active-user pricing starting at $4/user/month. [19][20][21]
  • Ideal if you need: A low-cost expense management tool with deep customization options and native integration with the broader Zoho ecosystem (Zoho Books, Zoho People, Zoho CRM). [19][20]
