What should it check?

Compare each supplier confirmation with your purchase order line by line. Your buyers review the differences instead of reading every reply.

One purchase order includes up to 20 order lines and 10 supplier messages or confirmation documents.

Your buyers approve every message and date change. No new orders, cancellations, price agreements or payments.

What is included

Read open order exports and supplier replies, match each confirmed line to the order, flag changed quantities, prices and dates, and draft a follow-up for unconfirmed or changed orders.

Start with open order exports, supplier replies and confirmation documents, your tolerance rules and checked examples. The connected option reads your purchasing system and mailbox, sends approved follow-ups and records approved dates; it does not place, cancel or change orders.

How reliable should the checks be?

A reply that says confirmed can still change a quantity or date. Choose how many lines must be read correctly, how many differences it must find and how reliable the drafts must be.

How these standards are measured

Test on held-out orders from suppliers not used for setup. Measure how many confirmed lines are read correctly and how many labelled differences are found. Partial confirmations, split deliveries and unclear replies must be flagged; a missing result is a failure.

Targets for your selected standard
What is checkedTarget
Confirmed lines read correctlyOrder lines where the confirmed quantity, unit price and date were read and matched correctly, divided by all confirmed lines in the test set.≥97%
Differences foundLabelled quantity, price, date, item and unconfirmed-line differences that were flagged, divided by all labelled differences; flags count only when the line is right.≥95%
Supported follow-upsDraft follow-ups where every order number, item, quantity, price and date matches the order and the latest reply, divided by all drafts.≥98%
Complete source linksEvery result must point to the order line and the supplier message or document page it came from.≥100%

Use exact arithmetic for quantities and prices and agreed tolerances for dates. A supplier message that says confirmed is not a confirmation of every line unless each line matches.

How quickly should an order be checked?

Choose how quickly a checked order should be ready after a supplier reply arrives. Your buyer’s review time is separate.

Timing details

Time from receiving a supplier reply to a stored comparison and draft follow-up, including document reading, line matching, queueing and retries. Confirm order sizes and peak volume with your provider.

The target applies to at least 95% of agreed test runs, with 4 in progress at a time.

How much do you want to spend per purchase order?

Choose the machine budget for reading replies and drafting follow-ups. Tighter budgets may use smaller models or fewer checks.

Cost details

Includes model calls, retries and shared hosting allocation. Buyer review, your purchasing system, email service and the calling agent are separate. Failed and repeated runs also consume resources.

Reference machine cost: $0.09 – 0.19 per purchase order at 400 purchase orders a month. The selected cap is a target to test, not a replacement for this estimate.

Where do you want it to run?

Keep purchasing data in your cloud or on your own server. Choose whether supplier replies may go to an approved AI service.

Data and access details

Runs in a cloud account you control, with access controls and logs.

Only approved order fields and supplier replies go to the selected external model. Agree access and retention first.

Read only the orders and mailboxes you approve and keep prices out of model calls where they are not needed. No external calls uses uploaded files and private inference; it cannot use the connected option.

How do you want to use it?

Use a review page, your current AI agent or a dedicated purchasing agent. You can choose more than one.

Anything else your provider should know?

Optional. Your choices are included automatically.

Common questions

Do I need this if my purchasing system already has supplier acknowledgements?

Not necessarily. If suppliers confirm through your portal or electronic messages, the built-in feature may be enough. Buy this when many confirmations still arrive as emails and documents that buyers read and compare by hand.

Will it accept new dates or prices for me?

No. It shows the difference and drafts a follow-up. Your buyer decides whether to accept a change, and the connected option records it only after approval.

Can it chase suppliers who have not replied?

Yes. It drafts a follow-up for unconfirmed orders. With the connected option, approved messages are sent from your mailbox with duplicate protection.

What about suppliers who write in other languages?

Include those replies in the test set and agree which languages are covered. Accuracy is measured on your own supplier messages.

Can I run it without an external AI service?

Yes, with uploaded files and private inference on hardware you supply. Measure reading quality and running cost during the pilot.
