I will automate supplier invoice processing into your accounting with n8n


About this gig
Supplier invoices arrive as PDFs in an inbox, as photos on WhatsApp, as attachments nobody files. At month end someone matches them to purchase orders by hand, and the differences surface three weeks after they happened.
I build the n8n or Make automation that processes invoices as they arrive. Each one is read by an AI extractor - supplier, invoice number, date, total, PO reference - matched against your purchase orders with a tolerance you set, and written to a reconciled list or an exceptions list with the reason attached. Nothing is discarded; an invoice that cannot be matched becomes a flagged exception, not a silence.
On Premium the result goes straight into your accounting system or ERP by API, with a duplicate check so the same invoice is never entered twice.
I have built this in production for a 70-person operation where invoicing, procurement and payroll ran through one system. Six weeks to production.
What you get
- A tested workflow handling your real invoice formats
- Reconciled and exceptions outputs you can act on daily
- Documentation, and handover in the order chat
Send me two or three sample invoices and I will tell you which package fits.

FAQ
Which invoice formats work?
PDF, scanned images and photos. Each supplier's layout is one format; Basic covers 2, Standard 5. More as an extra.
Which accounting systems can you deliver into?
Anything with an API: Xero, QuickBooks, Zoho Books, Odoo, SmartBill, and most ERPs. Tell me yours in the requirements.
How accurate is the extraction?
High on clean PDFs, lower on poor scans. That is why the workflow has an exceptions path - low-confidence results are flagged for a human, never written as fact.
What is the matching tolerance?
Your choice. It ships at 1 percent so rounding and partial deliveries do not create false exceptions. Change it in one place.
Where do invoices come from?
An inbox label, a shared folder, a WhatsApp number, or an upload form. Multiple sources are an extra.
Do I need n8n or Make?
One of them, yes. I can set up a self-hosted n8n for you as an extra if you have none.
Is my financial data safe?
I work inside your accounts, keep no copies, and sign an NDA through the order on request.
What if the workflow misreads an invoice after delivery?
Anything that does not match what was agreed is corrected at no cost. Premium includes 30 days of fixes for new formats too.
Can it handle multiple currencies?
Yes. Currency is extracted as a field and the comparison is made in the invoice currency.
Do you offer ongoing maintenance?
Yes, as a monthly custom offer scoped to your volume and formats.
