Use case

Invoice automation software that writes to your ERP

Invoices arrive in any format, language, or layout. Sainapse matches every line to your master data and posts a coded entry directly into SAP, Oracle, or your ERP of record. It replaces the keying step your AP team still does by hand, not the approval workflow your AP suite already owns.

Use caseUpdated August 2026
The problem

Invoices still arrive as PDFs, scans, and email attachments in a dozen vendor layouts, and someone in shared services keys every line into SAP or Oracle by hand.

A dedicated AP-automation suite handles approvals and payment runs, but it still needs a clean, coded invoice to start from: matched to the PO, the GL account, and the vendor master. That matching step is the one still done manually, line by line, invoice by invoice, and it's where the backlog lives.

Multiply a few minutes per invoice by the volume shared services sees in a month, and the labor cost is real. But the downstream cost of miscoded entries, duplicate payments, and a slower close is bigger, and harder to see.

How it works

How an invoice flows through Sainapse

1. Sainapse picks up the invoice.

Email, a shared inbox, a portal, or API. Sainapse reads the document in context (native PDF, scan, or photo), so a new vendor's layout doesn't need a new template.

2. Sainapse extracts and validates every field.

Invoice number, PO reference, line items, GL codes, tax, and vendor ID, matched against the master data you already maintain in SAP, Oracle, or your MDM. A line that does not resolve cleanly goes to a coder with the evidence attached, not into the ledger.

3. Sainapse posts the entry into your ERP.

High-confidence invoices post directly, coded and matched, into SAP, Oracle, or your ERP of record, with a full audit trail. Your AP suite picks up from there for approval and payment.

Sainapse vs. manual AP entry

Template OCR tools still need a fixed layout per vendor and hand the output to a person to code and key. Sainapse reads the invoice in context and writes the coded entry itself.

Common questions

An AP suite owns approvals, payment runs, and the general ledger. Sainapse doesn't replace it. Sainapse handles the step before that: reading the invoice, matching it to your master data, and posting a coded, ready-to-approve entry into SAP or Oracle, so your AP suite starts from clean data instead of a PDF.

Sainapse publishes the methodology instead of a single number. In one production document-intake deployment, 97.7% of all fields were accepted as-is with no human look, and the header field-edit rate fell from 8.4% to 1.37% as monthly volume grew ~13×. Results vary by vendor mix and document quality.

They route to a reviewer with the extracted fields, the matched master-data candidates, and the reasoning attached, instead of dropping into an unsorted queue. A reviewer's correction becomes training signal, so the same ambiguity is less likely to recur on the next invoice from that vendor.

Pricing depends on invoice volume, the number of ERPs and vendor formats involved, and how much of the coding-and-matching step you want automated end to end. Book a demo and we'll size it against your actual invoice volume and the systems involved.
