ROI payback
Accounts payable teams drown in PDFs, emails, and spreadsheets. Every invoice that arrives has to be re-keyed, matched, approved, and posted — and every manual touch is a place where errors, delays, and duplicate payments slip in.
We build AI invoice processing systems that handle the entire intake: OCR and vision models extract line items, vendor details, tax, and totals from any format — scanned PDFs, email attachments, or supplier portals. The extracted data is validated against your ERP, matched to purchase orders and contracts, and flagged for review only when something doesn't reconcile.
The result is an AP function that processes thousands of invoices a month with a handful of humans supervising exceptions instead of typing line items. You get a fully auditable trail, faster close cycles, and fewer duplicate or erroneous payments.
Invoice capture from scanned PDFs, email attachments, fax, and supplier portals using OCR, layout understanding, and vision models that handle tables, handwriting, and multi-page documents.
Extraction of vendor, PO number, line items, tax, currency, and totals — cross-validated against master data and your GL so bad invoices are flagged before they enter your workflow.
Automatic three-way matching against purchase orders and receiving records, with intelligent tolerance handling so routine mismatches auto-resolve instead of blocking payment.
Rules-based routing of exceptions and high-value invoices to the right approver, with a human-in-the-loop review queue, audit trail, and full GL posting integration.
Native sync with NetSuite, QuickBooks, Xero, SAP, or custom back-ends — two-way: approved invoices post automatically and status flows back to your AP dashboard.
Dashboards for processing time, exception rates, and cash-flow forecasting, plus duplicate-payment detection that catches re-submitted invoices before money moves.
We map your current invoice journey, sample 100+ historical invoices to understand format variance, and define the extraction accuracy and exception rules that matter for your business.
We configure the vision and extraction pipeline against your invoice formats, train it on your historical documents, and benchmark extraction accuracy against a held-out test set before integration.
The approved-invoice workflow connects to your ERP: exception queue, approval routing, GL mapping, and two-way sync. We run in shadow mode first — extracting and comparing against human output before automation goes live.
We flip the system to live, monitor extraction quality daily, tune exception rules, and hand over an ops playbook plus a 90-day support window with accuracy telemetry.
