How to Automate Epicor AP Invoice Entry: Every Option Compared

You can automate Epicor AP Invoice Entry at seven levels: DMT imports from a spreadsheet, a custom integration on the Kinetic REST API or Epicor Functions, Service Connect or Automation Studio workflows, RPA on the screen, Epicor's own ECM AP Automation, third-party AP automation such as Stampli or DynamicPoint EasyAP365, and AI agents such as Fluent. The first four move data you already have into Epicor; the last three also read the invoice itself. The right choice depends on where your invoices come from, how many are matched to purchase orders, and how much build work your team can own.

Why AP Invoice Entry is hard to automate

Keying an invoice is the easy part. The work in AP Invoice Entry is deciding what the invoice means inside Epicor:

• Which vendor sent it, when the name on the PDF does not match the vendor record exactly.
• Which purchase order and receipts it bills, and how much of each receipt is still left to bill.
• Which parts are on it, often written as the supplier's own part numbers.
• What unit of measure and currency each quantity and price is in.
• Whether freight, tax and misc charges have already been billed on an earlier invoice.

Any automation that only copies fields leaves those decisions to a person. The options below run from least to most of the job automated.

1. DMT (Data Management Tool) imports

Setup. Build a spreadsheet in the DMT template layout for AP invoice headers and lines, then run the import. Most Epicor administrators already know DMT from data migration.

What it automates. Bulk creation of invoice records from structured data. It is useful when invoices already exist as rows somewhere, such as a vendor portal export or a monthly utility bill file.

What falls to a person. Everything before the spreadsheet. Someone still reads each PDF, types the values, looks up the PO and receipt lines, and fixes rows the import rejects. DMT moves data; it does not read or match anything.

2. Custom REST API or Epicor Functions integration

Setup. A developer writes code against the Kinetic REST API, or builds Epicor Functions that an outside system calls. They need to know how AP Invoice Entry handles groups, receipt lines and validation.

What it automates. Whatever you build. Typically, invoices from a system that already holds structured data (an EDI feed, a supplier portal, another ERP) are created in Epicor without anyone touching the screen.

What falls to a person. Reading unstructured invoices, and maintaining the code. When a supplier changes its format or Epicor adds a required field in an upgrade, the integration is yours to fix.

3. Service Connect or Automation Studio workflows

Setup. Design a workflow in Service Connect (the older Epicor integration tool) or Epicor Automation Studio (the newer low-code option) that picks up a file or message and calls Epicor.

What it automates. Recurring, structured flows, such as a CSV dropped in a folder becoming invoices.

What falls to a person. The same as a custom integration: the invoice must already be data. These tools orchestrate; they do not extract values from a PDF or decide which receipt line an invoice line belongs to.

4. RPA on the screen

Setup. An RPA tool (UiPath, Power Automate Desktop and similar) records clicks and keystrokes in AP Invoice Entry and replays them with values from a spreadsheet or an OCR step.

What it automates. Typing. It can be stood up without API work, which is why it shows up in forum threads as a quick fix.

What falls to a person. Exceptions, and the upkeep. Screen automation is fragile: a Kinetic upgrade that moves a field, a new layout, a personalization, or an unexpected dialog stops the bot or, worse, puts a value in the wrong field. RPA is usually a last resort for systems with no API, and Kinetic has one.

5. Epicor ECM AP Automation

Setup. License and configure Epicor ECM, Epicor's content management product, with its AP Automation module. Configure capture, approval routing and the connection to Epicor. Epicor or a partner usually runs the project.

What it automates. Document storage, approval workflows and posting into Epicor, with capture of invoice data through Epicor's Intelligent Data Capture (IDC) layer. It is Epicor's own product, sold and supported by Epicor.

What falls to a person. Reviewing captured fields and handling invoices that do not match cleanly. How much matching logic you get out of the box, and how much is configured per vendor, is worth asking about in a demo.

Combining it with an agent. ECM and an AI agent work together. You can keep ECM as the archive and approval workflow and use Fluent in place of the capture step: Fluent reads and resolves the invoice, and the result is routed into the ECM workflow you already run. See Fluent with Epicor ECM.

6. Third-party AP automation (Stampli, DynamicPoint EasyAP365 and similar)

Setup. Subscribe, connect the product to Epicor, and configure approval routing. Implementation effort varies by product and by how many Epicor companies you run.

What it automates. These products focus on the AP process around the ERP: capturing invoices, routing them to approvers, collecting comments, and syncing approved invoices to Epicor. Stampli is known for collaboration on each invoice; DynamicPoint positions EasyAP365 for Epicor customers.

What falls to a person. Depends on how deeply the product matches against live Epicor purchase orders and receipts. Approval chasing across departments is what these tools are built for.

7. AI agents such as Fluent

Setup. Fluent connects to Epicor Kinetic's v2 REST API from outside. Nothing is installed inside Epicor: no customization, no BPM, no staging table, no import file. It works on-premise or Epicor-hosted, and restricted networks allowlist Fluent's fixed egress IPs. Each agent generates an Epicor access scope listing exactly the services it calls, which you import and Epicor enforces. Setup is about thirty minutes of accounts and onboarding, and most teams review documents the same day.

What it automates. Reading the invoice (PDF, scan, photo, spreadsheet, email body, XML or EDI) and drafting it in AP Invoice Entry against live Epicor data. The agent matches the vendor by name and tax ID, matches parts including the supplier's own part numbers, and runs two-way or three-way matching against the purchase order and the receipts behind it. Quantity is checked against what is left to bill, unit price against the order, and freight is never billed twice. On a partial shipment it offers only the quantity still left to bill. No templates per vendor, no model training: behavior is set with written instructions, and corrections become instructions. It can also validate invoices with fiscal authorities such as SAT in Mexico, DIAN in Colombia and SEFAZ in Brazil.

What falls to a person. Approving the draft. Every difference is shown on the line, and if no vendor matches, the invoice is drafted with a note of what was searched and waits for a person. Nothing posts until someone processes it, unless you set approval thresholds for low-risk documents. Across 25,359 reviewed documents in the 90 days to 1 September 2026, the median review took 55 seconds (the mean is 115 seconds, pulled up by a tail of long reviews).

Comparison table

What good AP automation in Kinetic looks like

Whichever option you choose, hold it to these checks.

Three-way match against the PO and the receipt

Match the invoice to the purchase order and the receipts behind it, so nothing is paid that was never received or already billed. Compare quantity against what is still left to bill and unit price against the order, and show each difference on the line.

Vendor resolution you can audit

Match on tax ID as well as name, so an invoice never lands on the wrong vendor or a duplicate record. When nothing matches, the tool should say what it searched and stop.

Units of measure and currency kept as the document states them

A supplier may bill in boxes while you stock in each, and in its own currency. Load each value in the unit and currency the document uses and let Epicor convert. A tool that assumes a default unit or converts prices itself creates errors that surface at month end.

Human review before posting

Automation should produce a draft a person approves, with an audit log of every field read and decision made, and Epicor's own business logic should validate it by the same rules your staff work under.

Which option fits

• Choose DMT if you have a small number of invoices that already arrive as structured rows, and no appetite for new software.
• Choose a REST API integration or Epicor Functions if a trading partner or upstream system already sends clean data and you have a developer who will own the code.
• Choose Service Connect or Automation Studio if you already run Epicor integrations there and the invoice data is structured.
• Choose RPA only as a stopgap where no API route exists, and budget for repairs after each upgrade.
• Choose Epicor ECM AP Automation if you want document management and approval workflows from Epicor itself and can run an implementation project. If you already have ECM, add an agent for reading and matching and keep ECM for the archive and workflow.
• Choose Stampli, DynamicPoint or similar if the bottleneck is approval routing and collaboration across departments.
• Choose an AI agent such as Fluent if the bottleneck is reading varied supplier invoices and matching them to POs and receipts in Epicor, and you want to start without an implementation project. It runs on its own or alongside ECM.
