An invoice can look complete and still be wrong. The supplier name is familiar, the total seems reasonable, and the payment deadline is close. But the quantity may differ from what arrived, a price may have changed, or a credit may still be missing.
A consistent matching process helps your team answer a simple question before approval: does this invoice reflect what we ordered, what we received, and what we agreed to pay?
Start with the three records
Bring the supplier invoice, purchase order or other authorized order record, and receiving record together. Each answers a different question:
- The order: What did the business agree to buy, at what price, and under which terms?
- The receiving record: What actually arrived, when, and at which location?
- The invoice: What is the supplier asking the business to pay?
Use the same supplier, location, and order reference to connect the records. If an order was agreed through another approved channel, attach that evidence rather than leaving the approver to reconstruct it.
Check identity and duplicates first
Confirm the supplier, invoice number, invoice date, location, and order reference. Search for the invoice number before entering a new payable. A second copy sent to another inbox should not become a second payment request.
If the invoice relates to several orders or deliveries, identify each one. Keep the relationship visible so a later reviewer can understand how the total was assembled.
Match quantities to what arrived
Compare each invoiced item and unit of measure with the receiving record. A case, an individual unit, and a package may represent different quantities. Resolve those differences before treating two numbers as a match.
Pay particular attention to partial deliveries, damaged goods, rejected items, and items received at a different location. Record what happened and who confirmed it. An order for ten cases does not establish that ten cases were received.
Where your business uses specialized inventory or receiving records, include the relevant references in the review packet. Follow your own receiving and recordkeeping procedures rather than substituting an invoice for evidence of receipt.
Compare prices and adjustments
Check unit prices against the authorized order or documented agreement. Then review discounts, freight, fees, credits, and other adjustments. Recalculate the total where needed, and make sure agreed credits have not been overlooked.
A difference may have a valid explanation. Capture that explanation and supporting evidence. Questions about accounting treatment or applicable charges should go to the responsible specialist rather than being resolved through an informal assumption.
Put exceptions in a visible queue
Separate a clean match from a record that needs investigation. For every exception, record the issue, the amount or items affected, an owner, and the next action. Examples include a missing delivery confirmation, an unexplained price change, or a credit the supplier has not issued.
A useful note is specific: “Two cases were not received; receiving lead is confirming the delivery record.” A vague note such as “check invoice” sends the next person back to the beginning.
Use your team's documented policy to decide whether an exception holds the entire invoice or can be handled separately. Any partial approval should make its scope clear and preserve the unresolved item for follow-up.
Give the approver a complete packet
Before requesting approval, attach the invoice, order reference, receiving evidence, and any exception resolution. Summarize the decision needed in a sentence: what matches, what changed, and what remains open.
The approver should be able to see the evidence and the limits of the request without searching through email. Approval should also identify the person making the decision and the time it was recorded.
Keep the process repeatable
Use a short checklist for every invoice: correct supplier and location, no duplicate, order identified, receipt confirmed, prices and adjustments reviewed, exceptions resolved or explicitly routed, and approval recorded.
Review recurring exceptions with purchasing, receiving, and finance. Repeated unit mismatches or missing references often point to a process that needs clearer inputs. Fixing those inputs can make the next invoice easier to review.
A clear match is more than a checked box. It is an understandable record of why the business is ready to approve a payment request.
