Guide for food business owners

How to read your Toast sales summary.

By Quinta Gaines, founder of KeyUna Data Studio · Updated July 2026

Toast's Sales Summary is one of the most complete reports any restaurant POS produces, which is exactly why so many owners glance at the top number and close the tab. This guide breaks the report down in plain English: what each section means, which numbers deserve a weekly look, and how to get the data out of Toast and into a form you can actually make decisions with.

Step 1: Find and export the report

  1. Log in to Toast Web (the back office, not the terminal).
  2. Go to Reports and open the Sales Summary.
  3. Set your date range. Start with the last full 4 weeks so you can see patterns, not one-off days.
  4. Use the export option to download a CSV or Excel file, or have the report emailed to you on a schedule.

Step 2: Decode the sections

The Sales Summary is organized into cards. Here's what the important ones are really telling you:

Toast calls itWhat it means for your business
Gross salesEverything ordered at menu price before deductions. Your ceiling for the period.
DiscountsComps, promos, and price reductions on food you still served. Money you chose to give away.
RefundsMoney returned after payment. Repeated refunds on one item are a quality or expectation problem.
Net salesGross minus discounts and refunds. Your real revenue, and the number to track week over week.
VoidsItems removed before payment (with amount, order count, and item count). Mis-rings, kitchen errors, walk-outs. An operations signal, not a revenue one.
Tips & gratuityYour team's money, tracked separately (including withholding if enabled). Keep it out of your revenue math.
TaxesCollected per tax rate you've configured. You're holding it, not earning it.
Sales category / revenue center summariesRevenue split by menu category and by where it was sold (dining room, takeout, catering, online). This is where the interesting patterns hide.
Voids vs. comps, in one line: a void means "we made a mistake before the customer paid"; a comp means "we served it and chose not to charge." Rising voids point at training or kitchen flow. Rising comps point at service recovery or promo creep. They need different fixes.

Step 3: Five things to look for

1. Net sales by service mode

The Service Mode and Revenue Center cards show whether dine-in, takeout, or online ordering is growing or fading. A shrinking dine-in number with growing takeout isn't a crisis. It's a staffing and packaging plan.

2. Category concentration

In the Sales Category Summary, look at what share of net sales each category carries. If beverages or sides are barely registering, that's usually your cheapest revenue growth. Attach them to your best sellers.

3. Void rate

Voids as a percentage of gross sales should stay low and stable. A creeping void rate almost always traces to a specific shift, station, or new hire. The report gives you the amount and count to narrow it down.

4. Discount weight

Total discounts divided by gross sales. When it drifts up month over month, list your active discounts and ask which ones still earn their keep. Legacy promos are the classic slow leak.

5. The same-weekday comparison

Compare this Tuesday to the last four Tuesdays, not to Saturday. Toast makes date-range comparison easy. Use it to separate "slow day" (normal) from "slowing trend" (act now).

Common mistakes to avoid

  • Treating total revenue as your money. It includes tax and tips. Net sales is the business's number.
  • Averaging across all days. A weekly average hides the fact that Friday carries the week. Look at the rhythm, not the mean.
  • Ignoring voids because "they're small." Voids are the cheapest early-warning system you have for operational drift.
  • Exporting once a quarter. By then a fixable pattern has cost you three months. A 15-minute weekly review pays for itself.

Quick answers

How do I export my Toast sales data?

In Toast Web, go to Reports, open the Sales Summary report, set your date range, and export it as a CSV or Excel file, or have it emailed to you. The export can then be opened in a spreadsheet or uploaded to an analysis tool like KeyUna.

What is the difference between voids and comps in Toast?

A void removes an item before it's paid for, usually a mis-ring or a kitchen error. A comp (discount) reduces the price of something you still served. Voids point at operational mistakes; comps are money you chose to give away.

Which number in the Toast sales summary should I track weekly?

Net sales, which is gross sales minus discounts and refunds. It's your real revenue and the fairest number to compare week over week.
