Accounts Payable Automation for Prophet 21 & IFS
Make invoice processing touchless. ESS Fusion AI reads any vendor invoice with template-free AI vision, validates it against your live ERP data, runs three-way matching against open POs and receipts, and writes the voucher directly into Prophet 21 / IFS — no re-keying into your ERP.
From a vendor invoice to a three-way-matched voucher in your ERP — not 10–20 minutes of manual keying, and no export file to re-key.
Why Manual AP Is Holding Your ERP Back
Accounts payable is one of the last fully manual workflows in most Prophet 21 and IFS shops — and it shows.
10–20 minutes per invoice
AP staff hand-key every header and line into the ERP — slow, error-prone work that scales only with headcount.
Template OCR keeps breaking
Zonal OCR tools fail the moment a vendor tweaks its invoice layout, sending "automated" invoices back to manual entry.
Extraction that stops at a file
Most tools hand you an export and call it done — your team still re-keys the voucher into Prophet 21 / IFS by hand.
Manual three-way matching
Matching invoices to open POs and receipts line by line is tedious, and discrepancies slip through into payments.
Backlogs grow with volume
Month-end and growth spikes pile up because the only lever you have is adding more people to key faster.
Every invoice gets a human
Without exception-only review, clean invoices and problem invoices get the same manual treatment.
From Vendor Invoice to Posted Voucher in Four Steps
Template-free AI vision, line-level extraction, automated three-way matching, exception-only review.
Read any layout
Template-free AI vision extracts every header and line-item field from any vendor invoice — no zones, no per-vendor setup.
Validate against the ERP
Vendor, items and GL accounts are resolved against your live Prophet 21 / IFS data in real time.
Three-way match
Each line is matched against the open PO and the receipt; tolerances and exceptions are applied automatically.
Write to the ERP
High-confidence vouchers are written directly into Prophet 21 / IFS; only exceptions route to an AP reviewer.
The system is self-improving — every reviewer correction sharpens extraction and matching, so the volume that posts straight through keeps climbing over time.
Extraction Is Only the First Step — We Write the Record Into the ERP
Most AP tools stop at extraction and hand you a file to import. ESS goes end-to-end from document to ERP transaction. We've built a simplified domain API on top of Epicor and IFS — a 150+ endpoint domain API covering invoices, POs, receipts and more — so AP automation doesn't just read an invoice, it completes the three-way match and writes the voucher directly into Prophet 21 / IFS. No Epicor API module required.

AP Automation for Prophet 21 & IFS — FAQ
What does touchless invoice processing mean for Prophet 21 / IFS?
Touchless means an AP invoice goes from inbox to a posted voucher in your ERP without a person typing it in. ESS Fusion AI reads every header and line-item field with template-free AI vision, validates the vendor, items and GL accounts against your live Prophet 21 / IFS data, runs the three-way match, and writes the record directly into the ERP. Only the invoices that fall outside tolerance are routed to a reviewer — that is exception-only review.
How is this different from OCR that just extracts the data?
Extraction is only the first step. Most OCR and capture tools stop there and hand you a file you still have to import and reconcile — the re-keying into your ERP isn't eliminated, just moved. ESS goes end-to-end from document to ERP transaction: after the AI reads and validates the invoice, it posts the voucher into Prophet 21 / IFS through our 150+ endpoint domain API. No Epicor API module is required.
How does three-way matching automation work?
For every invoice line, the AI matches the invoiced quantity and price against the open purchase order and the recorded receipt inside your ERP. Lines that match within your tolerances post automatically; price or quantity discrepancies, missing receipts and unmatched lines are flagged as exceptions with the source documents attached, so your team reviews only what genuinely needs a human.
Will it work for both Prophet 21 and IFS?
Yes. With 20+ years of integration experience and 25+ years across ERP platforms — including a 15-year IFS Gold Partnership — ESS maintains the domain API and AP pipelines for both Prophet 21 and IFS. The same template-free AI vision reads any vendor layout and writes the record directly into whichever ERP you run.
Where does our AP data go, and is it secure?
The platform runs in the client's own tenant on Azure or AWS with enterprise encryption, and your invoices are never used to train public AI models. For organizations with the strictest requirements, a fully air-gapped, self-hosted option is available.
How fast can we go live?
Because the ERP endpoints and AP pipelines already exist and there are no per-vendor templates to build, most clients run a pilot on their highest-volume AP invoices within days and expand from there.
