How to Check Supplier Invoices for Errors in a Restaurant

A busy back door is where invoice errors slip through. The driver is waiting, a line is forming at the pass, and the cases look about right. A short shipment here, a substituted item there, a price a few cents off, and it is easy to sign and move on. Dollar figures are illustrative examples.

Over a year those small errors add up, and the data on the invoice is also the most reliable record of what you pay. Catching errors and keeping the data are the same job.

The three-way match

Compare three documents:

1. What you ordered (your order or order guide).
2. What was delivered (what is physically in front of you).
3. What the invoice charges (items, quantities, unit prices, totals).

All three should agree. When they do not, you have a claim.

A receiving checklist

Do this with the invoice in hand, before the driver leaves.

1. Count cases or units against the invoice.
2. Weigh items sold by weight. Meat, fish and some produce are billed by weight, so check it.
3. Check product quality and condition, including packaging damage.
4. Check temperatures for refrigerated and frozen product against your food safety standard.
5. Check dates where product has a use-by or best-before date.
6. Check substitutions. Is that the item and brand you ordered?
7. Check unit prices against your last invoice or quoted price.
8. Note problems on the driver's copy before you sign: short, damaged, wrong, rejected.
9. Photograph anything disputed.
10. Put product away using FIFO rotation.

The five usual errors

• Short shipments: billed for more than delivered.
• Weight discrepancies: billed for the invoiced weight, received less.
• Substitutions at a higher price or lower quality.
• Price differences from what was quoted or the last invoice.
• Missed credits for earlier returns or promotions.

Also watch for duplicate invoices and unit mix-ups, such as per case versus per each.

An illustrative example

Invoice: 20 kg ribeye at $14.50 per kg = $290.00. You weigh it: 18.4 kg. You were billed for 1.6 kg you did not get.

1.6 kg x $14.50 = $23.20

If that happens weekly across a few items, it is real money. Note the shortage on the delivery slip before signing and ask for a credit.

Raise and track credits

• Contact your rep the same day, with the invoice number, item and photo.
• Confirm the credit in writing, and match it on the next invoice or statement.
• Keep a simple credits log so you can see which supplier or item causes repeat problems. That log helps when you consider switching suppliers.

Reconcile weekly

Once a week, compare invoices to the supplier statement. Look for duplicates, missing credits and total mismatches. It is a short job that catches what the back door missed.

Keep the data

Invoice prices are the foundation of recipe cost and price tracking. If invoices go into a drawer, that data goes with them.

Common mistakes

• Signing first, checking later.
• Checking totals only, not the unit prices and quantities beneath them.
• No scale at receiving.
• Not keeping a record of credits requested.
• Throwing invoices away after paying.

Where software can help

ChefMind AI's invoice automation reads invoice details into your records so quantities and prices are captured, with a review step before anything is saved. It does not replace the checking at the door, but it saves retyping afterward.

The short version

• Match order, delivery and invoice before the driver leaves.
• Weigh weighed items, check substitutions and unit prices, and note problems on the slip.
• Claim credits promptly, reconcile weekly and keep the data.
