Invoice processing that learns your business — and lives inside your books.

Merlin reads supplier PDFs, extracts every line item, suggests GL accounts, and posts transactions — inside your own system. It learns your specific business with every invoice it processes.

See how it works

Your data never leaves your system. No processing bureau. No outsourcing.

Every invoice still needs someone to open it, code it, and key it in.

📄

PDFs arrive. Someone opens each one.

Keys the figures into accounting software. Assigns accounts. Files the document. Repeat — every single invoice, every week.

💸

Outsource it and you're paying for data entry.

Your financials leave your system. Someone else's hands touch your supplier relationships and spending patterns. Then they send it back.

🤖

Generic AI doesn't know your business.

Off-the-shelf tools guess at account codes based on general patterns. They don't know that your Supplier A always goes to account 5100.

Four steps — from supplier PDF to posted transaction.

01

Invoice arrives

Upload a PDF manually, or drop it into a watched folder for hands-free batch ingestion. Merlin accepts any supplier format.

02

Merlin extracts everything

Supplier, invoice number, date, due date, every line item, tax, totals. Multi-currency invoices handled with live exchange rates.

03

Account codes suggested from your history

Merlin checks how you've coded this supplier before and applies the same logic — getting more accurate every month.

04

High confidence → auto-posted. Low confidence → review queue.

You set the threshold. Nothing hits the ledger without meeting it. Every AI decision is logged with confidence scores.

AI that knows your suppliers, your accounts, and your preferences.

🔒

Your data never leaves

Merlin runs inside your own environment. Every invoice, every GL posting, every AI decision lives in your database — under your control, with a full audit trail. No third-party access.

🧠

Learns your business specifically

Not generic accounting patterns — your suppliers, your accounts, your preferences. The more you use it, the smarter it gets for you.

Human review where it counts

Speed of automation on invoices Merlin knows well. Clear review queue for anything unusual. No silent errors buried in your accounts.

📒

Proper double-entry ledger

Not a simplified tracker. Full chart of accounts, tax rate handling, document sequencing. Built to support real bookkeeping work — just without the data entry.

Every step covered, from invoice to ledger.

"The difference between generic AI and Merlin is that Merlin knows your business — not just accounting in general."
