What Is AP Automation?

Definition

AP automation is software that captures, codes, routes for approval, and pays supplier invoices with little or no manual data entry.

Accounts payable is one of the most manual jobs in finance. Invoices arrive by email, mail, and supplier portals. Someone keys them in, chases approvals, matches them to purchase orders, and cuts checks. In businesses with many locations, like hotel groups or multi-yard equipment companies, the volume adds up quickly.

AP automation replaces those manual steps with software that handles the routine work and sends only exceptions to people.

Manual vs. automated AP workflow

A manual AP process usually looks like this: invoices are collected from inboxes and mailrooms, data is typed into the accounting system, paper or email approvals are chased, and payments are prepared one batch at a time. Lost invoices, duplicate payments, and late fees are common.

An automated AP process works differently:

1. Capture: invoices are forwarded to one inbox or uploaded, and the software reads the vendor, date, amounts, and line items.
2. Coding: the system suggests the GL account and dimensions, such as location or property, based on past invoices.
3. Approval routing: invoices go to the right approver automatically based on amount, location, or vendor.
4. Matching: invoices are matched to purchase orders and receipts where needed.
5. Payment: approved invoices are paid by ACH, virtual card, or check from one place.
6. Sync: bills and payments post to the general ledger automatically.

Key AP automation features

• Invoice capture with OCR and line-item extraction.
• Configurable approval workflows with mobile approvals.
• Two-way and three-way matching against purchase orders and receipts.
• Duplicate invoice detection.
• Integrated payments by ACH, card, or check.
• A searchable audit trail that stores every invoice and approval.

Integrating AP automation with your ERP

AP automation works best when it is tightly connected to your general ledger. Vendors, GL accounts, and dimensions should sync in both directions so invoices are coded the same way your books are structured.

For example, Ottimate's AP automation integrates with Sage Intacct. Invoices are captured and coded in Ottimate, approved by the right manager at each location, and posted to Sage Intacct with the correct entity and dimensions. That's especially useful for multi-entity organizations where one invoice may need to be split across properties or entities.

How to measure AP automation ROI

Two simple measures show the value of AP automation:

• Cost per invoice: total AP processing cost (staff time, software, postage, checks, late fees) divided by the number of invoices processed.
• Time per invoice: the average time from receiving an invoice to approving it for payment.

Measure both before and after automation. Also track invoice volume handled per AP team member, early-payment discounts captured, and late fees avoided. Faster AP also supports a shorter month-end close, because invoices are recorded as they arrive instead of piling up at month-end.

Example: a hotel group with 15 properties

A hotel management company receives invoices for food, linens, maintenance, and utilities at 15 properties. Each general manager approves invoices for their hotel, and some vendors bill several properties on one invoice. Before automation, invoices are scanned and emailed to the corporate AP team, keyed into the accounting system, and split by hand.

With AP automation, each property forwards invoices to its own inbox. The software reads them, suggests the account and property, splits shared invoices, and routes each one to the right general manager on their phone. Approved bills post to the correct property entity in the general ledger, and payments go out in one weekly run.
