Managing accounts payable—entering, approving, and paying a company's bills and invoices—can be a challenge, especially when bills arrive at different times in different ways and through different people. 

Some arrive by snail mail. Others are attached to emails sent to different managers throughout the organization. As companies grow, the problem only escalates.

With an increasing number of invoices, purchase orders, approvals, and receipts to manage, AP teams need a systematic approach to document management. The tips, strategies, and best practices included here can help.

What is document management in accounts payable?

Document management in accounts payable (AP) is the systematic organization, storage, retrieval, and tracking of all the financial documents and records that are related to the accounts payable process. This includes invoices, receipts, purchase orders, payment records, and any other relevant communication and documentation.

The goal of document management in accounts payable is to streamline and optimize the AP system—processing, approving, and paying invoices—ensuring accuracy, efficiency, and compliance with both financial regulations and company policies.

Why is accounts payable document management important?

AP document management is especially important for AP teams (or companies) that have outgrown the way documents were originally managed.

Most startups have a relatively simple document storage system. Paper receipts are kept in file folders. Invoices that are emailed from vendors are "stored" in someone’s inbox. As long as there aren't too many bills, the cost of managing the process and storing that documentation isn't very high in terms of either time or money.

Now imagine that same startup 100 employees later. Eight different department managers all receive invoices, but they aren't all equally fast at forwarding them to the AP team. Meanwhile, the AP team has grown too—and so has the number of bills that come in every month. Papers are starting to pile up.

If there's a problem with an invoice, that problem gets handled on an ad hoc basis. The person handling the error might be on top of it, but no one else in the organization has that insight. So the bill accidentally gets paid. When the issue gets fixed, the invoice is sent again, and a duplicate payment may occur.

A growing company needs a systematic way to enter, approve, and pay every invoice, no matter how or where it arrives. Purchase orders, invoices, approvals, and payment documentation need to be stored in one centralized place where anyone who needs that information can access it easily.

Accounts payable document management pain points

As companies grow, adding more staff, departments, locations, and expenses, their accounts payable departments often experience some or all of the following common pain points.

Difficulty tracking and organizing invoices

As more invoices come in the door, it becomes a struggle to keep track of them all. As a result, it's also more difficult for AP staff to find what they need, causing daily AP tasks to slow down and occasionally grind to a halt as teams search for paper invoices.

Lost or misplaced documents

As papers pile up, invoices, receipts, purchase orders, approvals, or even contracts may be lost or misplaced. This can lead to awkward calls from vendors who haven't been paid on time, missed payment discounts, or even security concerns, depending on the nature of what's been lost.

Inefficient approval processes

AP departments often face challenges in managing the invoice approval process. Delays in obtaining necessary approvals can result in late payments, strained relationships with vendors, and potential late fees.

Manual data entry

Another pain point is the need for manual data entry when receiving and processing invoices, costing AP teams valuable time. Manual data entry can also result in errors as AP staff members struggle to keep up with the continuing onslaught of paper documents.

Lack of transparency and visibility

Without a centralized system, teams don't have clear visibility into the status of invoices, approvals, and payments. This lack of transparency can lead to confusion, disputes, and potential missed payments.

Limited accessibility and collaboration

In a traditional paper-based system, accessing and collaborating on AP documents can be difficult, especially for remote or decentralized teams. If the AP team needs to contact traveling managers or work crews in the field about vendor invoices, there's a good chance that payments will be delayed.

Lack of integration with other systems

In many cases, accounts payable systems are not integrated with other financial or enterprise resource planning (ERP) systems. AP teams have to enter invoices manually in more than one place with a greater chance of errors and a lack of real-time synchronization between systems.

Compliance and regulatory issues

In a worst-case scenario, ensuring compliance with internal policies, regulations, and even tax laws can become a pain point in AP document management. Failure to comply with these regulations may lead to penalties, audits, or legal issues. 

Why are paper-based accounts payable document management systems ineffective?

The list above documents many pain points of paper-based systems, but those pain points add up to one key issue—paper-based AP document management doesn't scale.

As more people need access to documents, paper forms of invoices, approvals, and even payment become more problematic. That's why growing businesses eventually turn to a digital document management solution, providing wider document accessibility.

That said, there's a difference between document scanning and a true digital automation solution for document storage. Anyone who has had to scan even a dozen documents in a row can tell you that document scanning still involves a lot of manual work! 

Advantages of electronic document management

When companies implement true accounts payable automation software, the system does a lot more than digitize financial records. It streamlines the business processes associated with accounts payable processing.

An accounts payable automation solution can automate a wide variety of the manual tasks required for paper-based invoice processing—invoice entry, document routing for approvals, records management, syncing with accounting software, and even audit trails.

AP automation solutions can also simplify remote access for approvals and payments while helping to limit unauthorized access by letting teams set different permissions for different roles. 

7 AP document management best practices

By following these AP document management best practices, businesses can streamline their accounts payable processes, improve efficiency, reduce errors, and enhance overall financial management. 

1. Centralize document storage

Having a centralized and organized document storage system makes AP management much more efficient. Storing documents in one location ensures easy access and reduces the chances of misplacing or losing important documentation.

A cloud-based solution takes this one step further, ensuring that the AP team can access critical documents anytime, no matter where they are.

2. Digitize documents for electronic storage

Scanning physical documents and converting them into PDF files can be a first step toward digital storage. Electronic storage and retrieval is more efficient than paper systems, eliminating the great paper chase and reducing the extra costs associated with paper storage.

However, electronic invoices still require manual invoice processing—for the scanning process itself and for the data those invoices contain. Simply scanning a document won't enter the invoice number, payment date, billed amount, payment terms, company address, and other data points into an accounting system. 

To break away from manual processes, invoice document management needs to take advantage of more modern technologies.

3. Adopt optical character recognition (OCR) technology

OCR technology allows computers to pull data from scanned documents and enter it into an AP system automatically. This reduces the chance of human error and saves a significant amount of the AP team's time. OCR technology can capture key information such as invoice numbers, supplier details, payment amounts, and more.

By digitizing the actual information included in the invoice, accounts payable solutions can also check for duplicate invoices, keep track of early payment discounts, track payments, and more. It also allows for seamless integration with accounting software to keep books up to date automatically.

4. Establish approval workflows

Creating approval workflows for AP documents streamlines the approval process and ensures compliance with company policies and procedures. AP automation can then automate these workflows according to predefined rules regarding who needs to approve what.

Accounts payable software can support remote communication and approval, keeping all related communication and documentation in one storage system. It can even sync with a mobile app so approvers can take care of invoice approvals on a mobile device.

5. Set up access controls and permissions

Restrict access to AP documents based on job roles and responsibilities. Only authorized personnel should have permission to view, edit, or delete documents to maintain data integrity and prevent unauthorized access.

In a robust document management system, different roles will support different permissions. Approvers, for example, only need permission to view and approve documentation. By separating permissions by role, workflow automation software supports accounting best practices.

6. Establish backup protocols for AP documents

Implement a regular backup schedule to ensure the safety and continuity of AP documents. This will protect against data loss due to hardware failures, natural disasters, or cyberattacks. When designing your backup system, remember to think about the physical safety and redundancy of your file storage system as well as digital security.

Professional AP systems like BILL Accounts Payable are designed with both aspects of data security in mind, helping to protect data against both physical and digital hazards.

7. Keep an automatic audit trail

One of the biggest problems with paper documentation is that audit trails can be very hard to keep up with—let alone produce in case of an actual audit. With a cloud-based system like BILL Accounts Payable, audit trails are automated, capturing every action along the way with a timestamp and a record of what was done.

In the case of an actual audit, an automated system makes the process much faster and easier, allowing auditors read-only access to the system for a fully transparent process.

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).

  • 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]

  • 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]

  • 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).

  • 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]

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]

  • 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]
