Catch Invoice Differences Before You Pay

At Qvery, we help retailers save money, with custom AI agents that check supplier invoices and clean product data. We build them on your own systems. Supplier invoices arrive faster than anyone can check them against the order and the delivery. So a wrong quantity or a missing discount gets paid. The agent compares every invoice with its purchase order and with what arrived. Your accounts team decides what gets paid.

The agent shows the line, the value on each document and the difference in money. It compares quantity, unit price, discount, tax and total across the invoice, the order and the deliveries. Say the invoice bills more units than arrived: the line shows the invoiced, ordered and received quantities, and what the extra costs. A missing discount shows as a difference like any other. The buyer sees the amount in money and which document is off. The line goes to the buyer who owns that supplier, with the reason. A difference is a fact about three documents, never a verdict on the supplier.

The agent adds up every delivery note for that order. It compares the invoice with what has arrived so far, not with the whole order. For each invoice it first finds the purchase order and the delivery notes behind it, so the right ones are added up. Differences from a part shipment are shown with their amounts like any other. The result shows what matches, what does not and by how much. A receipt sent twice is counted once. When the next shipment arrives, its note joins the same order.

No. Invoices arrive by email as documents, spreadsheets or scans, and each supplier keeps its own layout. The agent reads each invoice as it lands in your payables inbox. Documents, spreadsheets and scans all go through the same check. The check starts as soon as an invoice lands. Your suppliers change nothing about how they send them. A value the agent cannot find on a document is marked not found, never passed as a match, whatever the layout.

No. It compares the documents and lists the differences. Recording and paying invoices stay with your team, in your own system. Matching invoices move on as they do today. The invoices that agree do not wait for the ones that do not. The agent never posts an entry or sends a payment. The buyer gets the difference to chase, and your accounts team gets the matching invoices to record and pay.

The line is marked not found and goes to your team to look into. It is never counted as matched, and the same goes for any value missing from a document. Not found is not a pass. It is not a verdict on the supplier either. The other lines on the invoice are compared as usual. It means one of the three documents lacks the value, and a person finds out why.

An agent for this job costs about $25,000 to build and $550 a month to run. The calculator above shows what that means against your accounts team's time. Put in your own team's numbers and the result updates as you type. By hand, each invoice means finding its order and delivery notes, then comparing quantity, price, tax and total. Repeating that for every supplier, each with its own layout, takes the time you see in the calculator. The agent does that for every invoice, so your team works on the differences.

The agent reads only the inbox and systems you connect it to and changes nothing in your books. You decide where it runs and how long anything is kept. It reads the invoices in the inbox you choose and the purchasing data you connect, such as purchase orders and delivery notes. Nothing else is read. Your team stays the only one that records and pays invoices.

We deliver a working agent in about two weeks, connected to your invoice inbox and purchasing data. It runs on real invoices beside your accounts team first, so they see its results next to their own work. Then each invoice is read as it lands. Any difference reaches the buyer with the reason and the amount. Your suppliers keep sending invoices the way they do now.

Your invoice checked on every line against the order and deliveries, with each difference and its amount. Each difference shows the value on the invoice, on the order and on the delivery. Lines with no delivery record are marked not found. You send one supplier invoice, its purchase order and its delivery note. The sample on the page is a replenishment invoice with its purchase order and two delivery receipts. It is the same check, on one invoice. It comes from vlad@qvery.ai within 15 minutes. We delete your files as soon as your result is sent.
