The “invoice approval workflow” consists of the steps your accounts payable department follows to reconcile and clear invoices — this typically includes:

• Matching invoices with the corresponding POs and receipts (and troubleshooting any discrepancies)

• Submitting verified invoices to a department head or manager for approval

• Sending payment to vendors

However, the time requirement and involvement of this process vary by approach, and teams who use AP automation software can save countless hours on data entry, avoid human errors, and send payments more efficiently.

Our guide compares the manual vs. automated approach to invoice processing and explains how ProcureDesk supports each step of the invoice approval workflow.  

Key Steps of the Manual Invoice Approval Workflow

Let’s consider an accounts payable team at a hypothetical manufacturing company. The process of receiving and reconciling invoices typically looks like this…

• Step 1: The AP team receives supplier invoices all throughout the month — sometimes they’re sent via email, other times in the mail, sometimes both, so you have to check for duplicates and ensure each invoice is new.

• Step 2: When a new invoice is received, the AP team has to source the purchase order (PO) and packing slip that match the invoice number; this is how they check the invoice for accuracy and confirm the purchase. Sometimes, teams have software or spreadsheets to store PO and purchase confirmations, but in other cases, these are stored in good old-fashioned filing cabinets. If AP teams cannot locate the corresponding PO or packing slip, they must loop in the purchasing team or purchaser to retrieve the proper documents. 

• Step 3: If there are any discrepancies with the order, this would be the stage to troubleshoot those with the vendor and receive a corrected invoice.

• Step 4: After the invoice match is complete and the purchase is confirmed, teams prepare payment by adding the correct accounting code and entering the invoice data into their accounting software or ERP. Then, they can send payment to the vendor or tag a manager to review and issue payment.

• Step 5: Once the invoice data has been recorded and payment is sent, AP teams can mark the invoice as paid so others know it’s been addressed. Payment status is logged in accounting software automatically, but many teams also will make a note on the paper invoice if they keep physical copies.

Challenges with Manual Methods

You can see in our explainer how this process could become quite tedious and time-consuming, and it’s rarely a one-person job. AP teams have to hunt down documents (in file cabinets!), double-check purchases, and manually enter invoice data into their accounting system.

Plus, this method is error-prone — teams may not catch duplicate invoices and send two payments, or they may not know about an issue with an order and send a payment for damaged or missing items. Or, they may hit an incorrect key when entering invoice data into the accounting system.

But most of all, this manual invoice approval process does not allow you to control costs. 

AP teams see purchases when they receive the bill for them — they have no idea what other teams are spending or what they’re spending on. They have to rely on other departments to manage their spending and hope everyone is adhering to budgets.

Surprise bills are one of the biggest pains we hear from AP teams still following this approach. Teams (accidentally) going over budget is a huge problem for AP departments. In cases where teams don’t have the funds to pay bills, they end up borrowing from credit lines, which can cause more severe problems.

How AP Software Automates the Invoice Approval Workflow

AP automation software, like ProcureDesk, facilitates each of the above steps; it saves time and enables better spend control while preventing duplicate payments, late payments, and other inefficiencies of the traditional accounts payable process.

Step 1: AP Automation Software Centralizes New Invoices & Detects Dupes

AP software connects with your email account(s) and lets you scan or upload invoices to organize vendor invoice documents in a centralized dashboard. Then, these systems use optical character recognition (OCR) to create new invoices from invoice documents automatically.

 

When these systems detect new invoices, they can scan the text to check if it matches an existing invoice. All duplicates are flagged and merged for improved invoice management.

Step 2: Automatic Invoice Matching Features Streamline Invoice Validation

AP systems provide two- or three-way matching features that support invoice reconciliation.

• Two-way matching is when a system automatically matches an invoice to the right PO.

• Three-way matching is when a system can match the invoice with the PO and the goods receipt.

 

Some systems only support two-way matching, but solutions with three-way match (like ProcureDesk) are preferred, as they automate the entire invoice validation process.  

Step 3: AP Systems Show Users Which Invoices Require Attention & Provide an Audit Trail

Most invoice-matching features can also flag invoices that require attention — perhaps the purchase receipt is missing information, or there was an issue with the order. Then, AP teams can see which invoices are ready for payment and which require troubleshooting with the vendor.

Bonus: ProcureDesk also has features to simplify this step. Our platform is a full procure-to-pay solution, which means it supports both procurement and AP workflows. It has features to:

• Streamline the purchasing process.

• Store POs and purchase confirmations in the same dashboard you manage invoices.

• Log notes about order status and condition.

• Automate invoice approvals… and more!

In the case where AP teams need to troubleshoot an invoice, they can find notes about orders right in our system (instead of reaching out to the procurement team or the person who made the purchase) and contact the vendor to find a resolution.

Step 4: AP Systems Automate Approval Routing & Integrate with Complementary Accounting Solutions

AP automation systems have:

• Auto-coding features to analyze invoice data and add the right accounting code.

• Automatic routing rules to notify the person(s) in charge of reviewing and approving invoice payments.

• Integrations with accounting and ERP software to push invoice data to those tools and prepare payment. (No manual data entry!) Then, teams can reference invoices in both systems without paper-based file keeping.

• Some AP automation software options have native payment processing tools, so you can issue vendor payments without exporting data or leaving the platform; this may be a perk for some users, while others will prefer to manage payments in existing accounting tools.

 

Step 5: AP Systems Keep Real-Time Invoice Status So Teams Avoid Duplicate Work

Once invoices are approved, and payment is sent, the invoice status updates in the AP system so users know they’ve been cleared.

AP tools keep a real-time status for every invoice (so users know what to work on).

Benefits of AP Automation Solutions

Having an automated invoice approval workflow alleviates a lot of the tedious parts of the AP process, allowing teams to focus on more important tasks — such as remediating discrepancies and sending timely vendor payments.

Avoiding late payments can keep you in good standing with vendors and improve supplier relationships; plus, you might even be able to snag early payment discounts by consistently issuing on-time (fast) payments.    

Many of these tools have features to implement budgets and improve cash flow visibility. You can process invoices as soon as they’re received to keep a near-real-time spending record and prevent others from going over budgets.

These tools also let you analyze spending to get a better understanding of how your teams use budgets. You can see which vendors you spend the most with, what users are buying, which departments spend the most, and more.

Then, if you need to reign in spending, you have data that can tell you where to start. The AP and finance department can also use these insights to negotiate vendor contracts and save money.

ProcureDesk’s Solution to Automate & Simplify Invoice Approval Workflows

ProcureDesk is a full procurement and AP automation software that connects purchasers, the procurement team, and AP departments — so everyone can work in parallel.

• Purchasers can shop with vendors and send purchase requests in our system. They can also see budgets (the total monthly allotment and what remains) so they can manage purchases more strategically.

• The procurement team can establish budgets and approval rules to ensure all purchases meet set criteria and users don’t overspend. (Our system will even block new purchases once budgets are met.)

• The AP team can see purchases as they’re made, in real-time, so they have full visibility into company expenses and know what invoices to expect. They can work with the procurement team and other departments to manage and optimize budgets and help pinpoint ways to increase savings.

Our software streamlines workflows for all user groups, with features like three-way matching, auto-coding, and auto-routing to support AP departments. ProcureDesk also integrates with solutions like QuickBooks, Sage, NetSuite, Xero, Dynamics 365, and Bill.com to manage vendor payments.
