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. Repeats — 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 from 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 or drop into a watched folder for hands-free batch ingestion.

02

Merlin extracts everything

Supplier, dates, every line item, tax, totals. Multi-currency with live rates.

03

Suggests account codes

From your own posting history — getting more accurate every month.

04

Posts or queues for review

High confidence, auto-posted. Low confidence, review queue. You set the threshold.

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

Privacy

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.

Personalised

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.

Oversight

Human review where it counts

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

Real bookkeeping

Proper double-entry ledger

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

Every step covered, from invoice to ledger.

Merlin knows yours.
