Workflows
Invoice processing, verification and receivables
Financial admin is one of the largest hidden costs: an average SME spends 6–12 hours a week on manual invoice entry, chasing approvals and phoning about unpaid invoices, while late customer payments are the number one cause of liquidity crises. These modules run the whole chain from intake through NAV cross-check to bank reconciliation and a psychologically staged dunning sequence.
- 6–12 hours a week spent on invoice admin at an average SME
- Fuzzy bank matching identifies 99% of payments even with wrong references
- Liquidity warnings 2–3 weeks ahead from partner payment habits

AI invoice intake and JSON extraction (IDP)
Invoices arrive by a dedicated address (szamla@ceg.hu), a synced Drive/OneDrive folder or a staff phone photo. Semantic vision AI extracts header fields (issuer, tax number, buyer, number, dates, due date, payment method, currency, IBAN), totals by VAT rate, and line items, even from crumpled fuel receipts and 20-page summary invoices.

Automatic 3-way matching and fraud screening
Invoice vs purchase order vs delivery note, with no human involved: unit price above the agreed one (overbilling), items never received, a bank account that differs from the supplier's known account (invoice fraud: payment blocked, CFO alerted), and duplicate detection so the same invoice is never paid twice.

NAV Online Számla automatic cross-check
Via the NAV M2M API the automation pulls the official XML for the invoice by tax number and invoice number, compares totals, VAT and dates with the PDF, checks that the issuer exists and its tax number is not suspended or on the tax-debtor list, and alerts finance on any discrepancy.

Predictive cash-flow and liquidity dashboard

Chase partners A and B now.' Weekly finance brief on WhatsApp or Slack every Monday at 8:00.
