Invoice Matching for Accountants — Manage Client Mandates Efficiently

If you run an accounting firm or tax advisory practice, you know the drill: every month, a stack of invoices lands on your desk — PDFs, scans, email forwards — and each one needs to be matched to a bank transaction. Multiply that by dozens of clients, and you have a recipe for late nights and missed deadlines.

invoice-matcher.io was built to change that.

The challenge

Accounting firms face a unique set of problems when it comes to invoice reconciliation:

Volume across mandates

You are not matching invoices for one business. You are doing it for ten, twenty, or fifty clients — each with their own bank accounts, vendors, and invoice formats. Keeping track of which invoice belongs to which client, and which transaction matches it, is a logistical challenge.

Inconsistent document quality

Some clients send well-structured PDFs. Others forward blurry phone photos or handwritten receipts. Your workflow needs to handle all of it without grinding to a halt.

Time pressure around deadlines

Monthly and quarterly closings create predictable bottlenecks. When all your clients need their books done at the same time, manual matching simply does not scale.

Client expectations are rising

Clients expect faster turnaround, transparent status updates, and clean exports. Delivering that with spreadsheets and manual processes is increasingly difficult.

How invoice-matcher.io solves this

One tool, many mandates

Each client gets their own organization within invoice-matcher.io. Invoices, transactions, and matches are strictly separated. You switch between clients in seconds — no mixing of data, no risk of cross-contamination.

AI extraction handles the mess

Upload a PDF, a scanned image, or forward an email. Our OCR + AI system extracts vendor name, amount, date, invoice number, and VAT ID — regardless of document quality or layout. All processing happens within the EU, on servers in Frankfurt and Paris.

Automatic matching saves hours

Once invoices are extracted and bank statements imported (CSV or OFX), our matching engine compares them across five data points: amount, date proximity, vendor name, invoice reference, and currency. High-confidence matches are assigned instantly. Ambiguous cases go to a review queue where your team can approve or reassign them.

Export-ready for clients and tax offices

When the matching is done, export everything as a structured ZIP file — PDFs organized by match status, plus a summary CSV. Hand it to your client, upload it to DATEV, or archive it for the tax office. No reformatting needed.
