Invoiceflow captures invoices from email and the supplier portal, matches them to the PO and receipt, and checks rates, discounts and tax terms against the signed contract. Exceptions go to a person before anything is paid. Our customers ## Procurement, legal, IT, finance, and sales teams run their contracts on Aavenir. American Seafoods Group T.D. Williamson Thrive Express Employment Professionals MUFG State of Utah Definition ## What is accounts payable automation? Accounts payable automation is software that captures supplier invoices, extracts their data, matches them to purchase orders and receipts, routes exceptions for approval and tracks payment, so AP stops keying and chasing invoices by hand. Most AP tools stop at the purchase order. Aavenir Invoiceflow also reads the signed contract in [Contractflow](https://aavenir.com/solutions/enterprise-contract-management-software/), so a rate, discount, tax or VAT term that differs from what was agreed is held before payment, with the clause cited on the exception. - Captures invoices from email, the supplier portal and other sources - AI and OCR extraction, with bundled invoices split automatically - 2-way and 3-way matching against PO and goods receipt - Contract pricing, discounts, tax and VAT terms checked against the signed contract - Confidence thresholds send exceptions to a person Where AP loses time and money ## A matched invoice can still be the wrong amount. The PO says what was ordered. Only the contract says what was agreed. Four gaps Invoiceflow closes. ### Paper and PDFs everywhere Invoices arrive as paper, PDFs and attachments, and someone retypes every line. Email and portal capture. AI and OCR extraction. Bundles split automatically. ### Matching stops at the PO A PO can carry the wrong rate, and a 3-way match will happily approve it. Contract pricing checked. Discounts and tax terms checked. Clause cited on the hold. ### Coding from memory GL codes and receiving checks depend on one person knowing each vendor. Coding suggestions. Receiving on the record. Confidence thresholds. ### Nobody knows where an invoice is Suppliers call AP, AP emails budget owners, budget owners guess. One status for everyone. Supplier portal view. Decisions kept on the invoice. How it works ## One invoice, from inbox to payment. - Email, supplier portal and other sources AI and OCR extraction of header and line detail Bundled invoices split into separate records. - 2-way and 3-way matching PO and non-PO invoices Routing by vendor type, spend category or risk. - Contract pricing and discounts Tax and VAT terms The clause is cited on every exception. - AI learns invoice patterns and suggests coding Receiving for services confirmed on the record Confidence thresholds decide what a person reviews. - AP, budget owners and suppliers see the same status Suppliers check the portal instead of calling Every decision stays on the invoice record.

A 3-way match compares the invoice with the purchase order and the goods receipt. Contract matching adds a fourth check: the rate, discount, tax and VAT terms in the signed contract. If the PO itself carries the wrong price, only the contract check catches it. [See invoice to contract compliance](https://aavenir.com/use-cases/invoice-to-contract-compliance/). ### ### Can Invoiceflow handle non-PO invoices? Yes. Invoiceflow handles PO and non-PO invoices, routing each by vendor type, spend category or risk. Non-PO invoices go to the right budget owner for approval, and the decision stays on the invoice record for audit. [See invoice workflow](https://aavenir.com/solutions/invoice-workflow-software/). ### ### Does Invoiceflow run on ServiceNow? Yes. Invoiceflow is built natively on ServiceNow, and the State of Utah runs it on its existing Now platform for IT vendor invoices. Organizations without ServiceNow can run Invoiceflow standalone with the same capture, matching and contract checks. [Compare deployment options](https://aavenir.com/platform/deployment-options/). ### ### How does AI invoice processing work in Invoiceflow? AI and OCR read the invoice header and lines, split bundled files into separate invoices and suggest coding based on learned invoice patterns. Confidence thresholds decide which results a person reviews before the invoice moves on to matching and approval. [See AI invoice processing](https://aavenir.com/solutions/ai-invoice-processing/).
