Every time your business submits a purchase order (PO), it kicks off a chain of events involving your team and trade partner. Each touchpoint represents a potential friction point unless your organization has mastered the art of purchase order management.

Managing purchase orders effectively is crucial for maintaining smooth operations and ensuring adequate financial visibility. Our list of seven purchase order management best practices will help you streamline your purchase order process.

Key takeaways

The better your purchase order management process, the more time you'll save.

Proper oversight of POs reduces administrative burden and ensures compliance with budgetary constraints.

Implementing automation tools can significantly improve the procurement process.

What is purchase order management?

Purchase order management involves creating, tracking, and fulfilling purchase orders within a business. It encompasses everything from requisitioning goods or services to receiving and paying for them. 

Effective management ensures that orders are placed correctly, suppliers are notified, and inventory levels are maintained accurately.

PO management involves more than the procurement team. The purchasing process begins with the creation of a purchase requisition, meaning every department across all levels of the organization will impact the purchase order process.

Suppose your team members don't know the proper procedures for filling out a purchase request. In that case, you may experience delays in your procurement process, which could lead to vital equipment or inventory shortages.

Your purchase order management process must holistically address every facet of buying goods and services. The earlier you get involved in procurement, the easier it will be to optimize purchase order management.

Why is purchase order management important?

Purchase order management directly impacts several key areas of your business. Optimizing the way you manage purchase orders can help you exercise better budget control. By tracking commitments and expenditures, you can maintain spending within allocated budgets.

Purchase orders are legally binding documents. Once you and your supplier sign the form, the agreement can not be broken. If an incorrect purchase order accidentally gets executed, it is still a legally binding document, even if it has errors.

Your business would be legally obligated to adhere to the purchase order terms. If you have good supplier relationships, your trade partner may allow you to return the excess items. However, you will still have to pay hefty restocking and return shipping fees.

Good purchase order management helps prevent costly errors and promotes better supplier management. Automated solutions to help with PO management can also alleviate the burden of manual data entry and make it easier to catch errors.

7 best practices for managing purchase orders

Here are seven ways to improve your procurement process flow through PO management optimization.

Best practices for purchase order management

1. Standardize your process

A standardized purchase order process will promote better efficiency and reduce the risk of errors. Your team needs clear guidance regarding every step of the purchase order process, including:

  • How to initiate the purchasing process
  • What the approval process is for requisition forms and POs
  • What details to include on purchase orders
  • Who to send POs to

Your purchasing policy must thoroughly address both internal and external purchasing processes, including rules for submitting and approving POs.

Start by reviewing your current process and set of policies. Consider the scope of your policies and ensure they address any questions or concerns your team members may have. Spell out everything, including a list of details required for purchase orders.

Once you've created a standardized process and set of policies to govern all procurement activities, it will be much easier for your team to complete and submit purchase orders.

2. Use purchase order management software

With purchase order management software, you can automate various procurement processes, including sending multiple purchase order documents, obtaining necessary approvals, and more.

PO software centralizes all procurement activities and automates approvals. Real-time tracking for order statuses makes it easy to match invoices with corresponding purchase orders. Tracking POs and projected fulfillment times will help you stay within your inventory threshold and avoid critical product shortages.

A top purchase order system will also help with back-end aspects of inventory management and accounting. By integrating with your resource management technologies, leading procurement software can assist with shipment and quality inspection, reconciling invoices with POs, stock management, and supply chain optimization.

Consider technologies that readily integrate with your existing enterprise resource planning and accounting platforms when exploring PO software solutions. Integrating your technologies will provide a holistic view of your supply chain while modernizing your purchase order management capabilities.

3. Maintain accurate records

Detailed purchase order records are invaluable for tracking expenses and resolving any discrepancies that may arise. Accurate records help in auditing and providing a clear history of all transactions.

Relying on manual processes makes it incredibly difficult to maintain accurate records as manual data entry sets the stage for human errors.

Digitizing purchase order management will help you stay organized and automate redundant tasks while your team can use their talents for more strategic tasks that add value to your business.

By increasing your ability to maintain accurate records and mitigate mistakes, PO software can also drastically improve financial visibility.

4. Define approval hierarchies

Do you have a clear approval hierarchy for reviewing and signing off on purchase orders? If not, it's time to consider what an approval process might look like for your business.

Approval hierarchies ensure major purchases don't slip through the cracks. Make sure all relevant stakeholders are aware of your approval workflow. Your accounting department and all department heads must know what the PO process is and when they have to forward requests up the chain to the finance director.

For example, say a healthcare organization has a two-stage invoice approval process. Department heads can approve orders up to $5,000. If they receive a requisition higher than that, they must sign off on the request and then send it to the finance director for final approval.

5. Implement 3-way matching

Three-way matching is a critical step in your approval workflow. It compares the purchase order and delivery receipt to the supplier's invoice. This ensures the quantities and prices match all three documents before paying your suppliers. A thorough matching process helps prevent overpayments and fraud.

Automate 2-way and 3-way matching with BILL.

6. Monitor supplier performance

Purchase order management solutions provide a means of evaluating supplier performance to ensure quality and reliability. Track key performance indicators such as:

  • Delivery timeliness
  • Product quality
  • Adherence to contract terms

You can identify underperforming suppliers and take corrective actions by monitoring these metrics. 

For example, say that one of your trade partners consistently fulfills POs a few days late, which violates your contract terms. Your leadership team can evaluate this trend and determine whether it negatively impacts your company's operations.

During future contract negotiations, you can address the issue with your supplier and potentially implement a penalty system for violations of terms. For example, you may require them to offer a 5% discount on all late deliveries. Alternatively, you can explore different suppliers who can meet your performance needs.

7. Regularly review and update processes

Purchase order management isn't a "set it and forget it" process. You must continually assess and update your PO processes to maintain efficiency and compliance. This involves periodically reviewing workflows and conducting performance audits.

During your assessments, it's essential to evaluate your software's capabilities. Is your technology suite effectively meeting your organization's needs, or are you being hampered by redundant workflows? 

If the latter is true, it may be time to replace legacy software with modern purchase order management technologies with automation capabilities.

How automation can help with your purchase order management

BILL Accounts Payable includes automatic three-way matching to detect discrepancies sooner and reduce the risk of fraud or other critical errors.

It has helped countless businesses gain valuable visibility into their purchase requisition process. For example, Myomo, a wearable medical robotics company, integrated BILL with NetSuite. 

Our platform automatically syncs purchase orders and item receipt details from NetSuite to our workspace, providing Myomo with a unified view of POs and invoices.

Another BILL customer, aboutGOLF, relies on our three-way matching capabilities to prevent discrepancies and avoid costly billing errors. 

Like Myomo, aboutGOLF also took advantage of BILL's ability to integrate with top solutions like NetSuite. The client can now review and analyze purchase orders alongside invoices in our user-friendly workspace.

  • 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).

Pricing

4 on G2
  • 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]

  • 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]

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
Best for budget-conscious teams
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]
