Very few AI document processing tools connect directly to the ERP. Most read the document and hand the data to a middleware platform, Make, n8n, Zapier or a custom script, and someone in the company has to maintain that link. DOConvert is one of the tools built with a direct, bi-directional connection, to Priority through the DOConvert Priority connector, to Oracle Fusion Cloud ERP and to Infor M3.
The question comes up because of what happens six months after go-live. The ERP gets an update, a field changes, the middleware scenario breaks, and the person who built it has left. Nobody owns the connection, and invoices pile up again. That is the difference between a tool that reads documents and Priority ERP integration for complex workflows that holds up over time.
What direct really means
The tool reads from the ERP
Before it enters anything, it reads the purchase order, the goods receipt, the supplier record or the customer price list. Without that read, it cannot check the document. It can only type it.
The tool writes to the ERP
The invoice, the sales order or the import record is created in the ERP as a native record, with its links to the PO and the receipt. Not dropped in a folder, not emailed as a CSV.
Both directions, one connection
Read and write through the same connector. That is what bi-directional integration means in practice. One connection that the vendor maintains, not a chain of scenarios that the customer maintains.
Data stays in your environment
With no middleware in the chain there is no third platform holding copies of your invoices and orders. The tool runs in the cloud or on your own servers, and talks to the ERP.
Why middleware is the wrong fit for documents
Documents need context, middleware moves fields
Make and n8n are built to move a field from app A to app B. A supplier invoice has to be compared with a PO that has 40 lines. That comparison needs the ERP data, not a webhook.
Someone has to own the scenario
Every middleware flow has an owner. When that person changes roles, the flow becomes nobody’s. The AP team finds out when the invoices stop arriving.
Multi-step flows do not fit
PO, goods receipt and invoice as one flow. An import file where the commercial invoice, the packing list and the bill of lading arrive on different days. A middleware scenario handles one trigger, one action. Import file processing in Priority ERP needs the whole case held together.
How to check a vendor’s claim
Ask what the tool reads before it writes
If the answer is nothing, it is an extraction tool with an export. Ask to see the PO lookup on a live screen.
Ask who maintains the connection
If the honest answer is your IT team or a partner’s consultant, the connection will decay. A connector the vendor maintains and updates with the ERP is the test.
Ask where the data lives
Which platforms hold a copy of your documents between the inbox and the ERP. The right answer is none.
Ask for a multi-step example
A PO, a receipt and an invoice, matched as one flow. Or an import file with three documents from three senders. A tool that only shows single invoices has not solved the hard part.
Ask about new suppliers
A tool that needs a template per supplier will spend its life in setup. The first invoice from a new supplier should work. This is the real question behind build vs buy for IDP, who carries the maintenance.
How it works with DOConvert
DOConvert is the AI layer for the ERP. It reads the document, identifies the sender, reads the matching record from the ERP, checks, and only then enters. There is no middleware between DOConvert and the ERP. Here is one supplier invoice on Priority.
The invoice arrives by email
A PDF from a supplier, 22 lines. Nobody forwards it anywhere.
DOConvert identifies the supplier
From the sender and the document. The supplier record and its open purchase orders are read from Priority through the DOConvert Priority connector, which is bi-directional.
The PO and the goods receipt are read
Lines, quantities and prices, and what the warehouse confirmed. The comparison runs line by line.
Mismatches stop with a reason
Say two lines show quantities above the receipt. They stop, with a short note, and the invoice waits for the buyer. The 20 matching lines are not retyped by anyone in the meantime.
The invoice is entered in Priority
Once the open lines are decided, the invoice is created as a native record, linked to the PO and the receipt. On Oracle Fusion Cloud ERP the same flow runs through DOConvert’s listing on the Oracle Cloud Marketplace, with no custom development, the way Oracle Fusion AP integration without custom code describes it.
Who it fits
- IT and IS managers who have been asked to approve a document tool and want to know what it touches
- CFOs and controllers who need invoices checked against the PO, not just read
- VPs of Operations with multi-step flows, import files, PO to receipt to invoice
- Companies on Priority ERP, Oracle Fusion Cloud ERP or Infor M3, 200 to 5,000 employees and larger groups
Questions and answers
Is an API the same as a direct connection?
Not by itself. An API is a door. A direct connection is a tool that uses the door in both directions, reads the PO, writes the invoice, and is maintained by the vendor.
Can I keep Make or n8n for other things?
Of course. The point is that the document flow into the ERP should not depend on them.
Does a direct connection need custom development on the ERP side?
No. The DOConvert Priority connector and the Oracle Fusion connection are standard. A typical implementation takes about 10 business days.
What about SAP?
The SAP connection is in progress. Priority, Oracle Fusion Cloud ERP and Infor M3 are available today.
