Comps and voids look similar on a POS report but they represent completely different things. Treating them the same way in your books will distort your revenue numbers and make it harder to spot problems like theft or excessive giveaways.

A void happens when someone rings in the wrong item or enters a duplicate before the order goes through. The guest never received the item, no food was prepared, and no sale took place. Voids should cancel the transaction entirely so it never touches your revenue. Your POS system should remove the item from the ticket as if it was never there. In your accounting software, a voided item shouldn’t appear anywhere in revenue or expenses because nothing actually happened.

A comp is different. The guest received food or drinks, the kitchen prepared the order, and real costs were incurred. The business just chose not to charge for it. Maybe it was a manager comp for a long wait, a promotional offer, or a meal for a VIP. Comps should be recorded in a contra-revenue account, often called something like “Comps and Promotions” or “Complimentary Sales.” This account offsets your gross revenue so your financial statements show the true picture. You had $50,000 in gross sales and $1,200 in comps, giving you $48,800 in net revenue. That distinction matters because your food cost percentage should be calculated against gross sales including comps, since the kitchen still used ingredients for those meals.

Your POS system is the starting point for tracking both accurately. Most modern restaurant POS systems have separate buttons or workflows for comps and voids. Make sure your staff knows the difference and uses the right one. A common mistake is voiding items that should be comped, which hides the true cost of giveaways. Require manager authorization for both comps and voids so there’s accountability and a paper trail.

Daily reconciliation is what ties everything together. At the end of each shift or day, pull your POS summary report and review the comp and void totals. Compare expected cash and card payments against what was actually collected. If voids are unusually high, that could signal training issues or something worse. If comps are climbing, you need to understand why and whether the reasons are legitimate. Restaurant bookkeeping depends on this daily discipline because waiting until month-end to catch discrepancies means you’ve already lost visibility into what happened and why.

In QuickBooks or whatever accounting software you use, set up a dedicated contra-revenue account for comps. Don’t lump them into a general discount line or bury them in an expense account. Keeping comps visible on your profit and loss statement lets you monitor trends over time. A restaurant giving away 5% of gross sales in comps has a very different situation than one at 1%, and you can’t manage what you can’t see.

If your current books don’t separate comps from voids or your POS reports aren’t giving you the detail you need, it’s worth getting this fixed sooner rather than later.
