When opening hours change, compare both total sales and sales per open hour over equivalent completed periods. Total sales show how much business you took in; sales per open hour show the sales generated for each hour the restaurant was available to guests. Neither measure alone tells you whether the schedule was more profitable.
Before trusting a dashboard comparison, agree on what counts as an open hour. A scheduled closure, a break between services, and a temporary outage can produce different denominators. Ask the vendor to show the underlying sales and hours as well as the calculated rate.
Build a sample week with one shorter service
Start with a completed week before the schedule change and a completed week after it. Match the same days of the week and use the same sales definition. A Tuesday-through-Sunday restaurant, for example, should not compare six trading days with a seven-day week.
The following figures are hypothetical. The restaurant opens six days a week. In the first week, it opens eight hours each day. In the second, it opens five hours on Tuesday and keeps the other five days unchanged. Sales are measured consistently across both weeks.
| Measure | First week | Shorter-service week | Change |
|---|---|---|---|
| Tuesday open hours | 8 | 5 | −3 |
| Tuesday sales | $800 | $590 | −$210 |
| Other five days: open hours | 40 | 40 | 0 |
| Other five days: sales | $4,000 | $4,000 | $0 |
| Full week: open hours | 48 | 45 | −3 |
| Full week: sales | $4,800 | $4,590 | −$210 |
| Full week: sales per open hour | $100 | $102 | +$2 |
The table separates the changed service from the rest of the week. Weekly sales fell $210, or about 4.4%, while the weekly sales rate rose from $100 to $102 per open hour. Tuesday's rate rose from $100 to $118. The higher rate does not recover the missing $210 in total sales.
These figures include sales only. They exclude fixed costs, variable costs and exception costs, such as an unusual repair or extra cleaning. They do not measure profit or show whether shortening Tuesday saved enough labor or other expense to offset the sales reduction.
Compare total sales and sales per open hour
Calculate the rate by dividing sales for the selected period by the actual hours included in that same period. In the shorter-service week, $4,590 divided by 45 open hours equals $102 per hour. Keep the numerator and denominator visible so you can check the result.
Use total sales to answer: “How much business did we take in during this week?” Use the hourly rate to answer: “How much business did we take in per hour available to guests?” The two answers can move in opposite directions, as they do here.
Next, look at the changed service on its own. A weekly average can hide a weak or strong shift because unchanged days make up most of the hours. Compare the same weekday and the same service window where possible. If the restaurant dropped its final three Tuesday hours, look at those hours separately in earlier weeks. A busy lunch followed by a quiet late afternoon calls for a different decision than a consistently busy day.
Decide which sales belong in the numerator before comparing reports. For example, will you use sales before or after discounts and refunds? Are canceled orders excluded? How are sales from orders placed before opening but fulfilled during service handled? Keep the definition consistent, and reconcile the report to your restaurant POS system or other sales records.
Also separate order source from dining option. An order placed online and picked up at the restaurant has an online source and a pickup dining option. If you compare channels, avoid counting the same order twice or treating a change in channel mix as proof that the hours caused a change in demand. Deposits are not the same measure as sales; decide how they appear in the report rather than adding them automatically.
Check how closures and breaks affect the denominator
Scheduled hours are a starting point, not always a record of actual availability. If a restaurant closes between lunch and dinner, those closed hours should not be counted as open hours in a sales-per-open-hour calculation. A dashboard that spans the whole day without removing the break will produce a lower rate.
Temporary closures need an explicit rule too. If the dining room is unavailable but pickup remains open, decide whether your question concerns the whole restaurant or only dine-in service. For a channel-specific rate, the hours should reflect when that channel could accept orders. Record the reason for each exception so a future comparison can use the same rule.
Ask a vendor to demonstrate the calculation with a split service and a temporary closure. Use simulated records and confirm that the exercise cannot send a guest message, take a real payment or dispatch a courier. The demonstration should show:
- The sales amount, included hours and resulting rate for each period.
- Whether hours come from a schedule, manually entered actual hours or another record.
- How the report treats a break, a closed day and an unexpected interruption.
- Whether you can inspect the dates and service windows behind the comparison.
- How corrections to sales or hours affect a report after the original week ends.
If the dashboard cannot supply reliable actual hours, keep an hours log and calculate the rate separately. That adds work, but it is better than dividing by a convenient number that includes closed time. Ask whether the report can provide the underlying figures in a usable form; do not assume a particular export is available.
Open hours are also different from staff hours. One hour open with several employees working is still one open hour, but it represents several labor hours. For the staffing side of the decision, use a separate comparison such as the guide to comparing labor hours with sales by shift. Payroll or accounting tools may still be needed to evaluate costs.
Choose a comparison and record your acceptance criteria
For the hypothetical week, the first decision is to investigate the $210 sales decrease, not declare the shorter schedule a success because the hourly rate rose. The five unchanged days have identical sales in this example, so the entire weekly decrease occurs on Tuesday. The owner should examine earlier Tuesday service windows and the costs associated with the three removed hours before deciding whether to keep the schedule.
One pair of weeks cannot establish cause. Holidays, weather, local events, promotions, menu changes and staffing can all affect demand. Compare several comparable completed weeks when available, note unusual events, and check whether orders shifted to other times. Even then, the report supports a judgment; it cannot isolate every reason a guest did or did not order.
Write acceptance criteria before a vendor demonstration. For this purchase, an owner might require the following:
- Compare two selected completed periods with total sales, included open hours and sales per open hour visible together.
- Inspect the changed weekday separately from the full week and apply the same sales definition to both periods.
- Exclude a closed break from open hours, or provide enough underlying data for the owner to do so accurately.
- Identify temporary closures and explain how corrections appear in the comparison.
- Reconcile the sales figure to the restaurant's sales records without counting deposits as sales or duplicating orders across channels.
Mark each requirement as demonstrated, achievable with a separate calculation, or unresolved. A manual workaround may be acceptable for a weekly review; it may be too burdensome if a manager needs the comparison every day. Ask who enters actual hours, how long that takes, and who checks exceptions.
Fleksa's partner portal provides dashboard, order, menu and reservation views, including sales and order summaries for a selected period. Ask to see whether the available configuration supports your specific hours comparison or whether you would need a separate worksheet. For current plan pricing, consult Fleksa's plans, checked November 2026, and request a quote for your setup. Compare the quoted operating total, including any separate processing or other relevant charges, rather than assuming the plan price covers every cost.
Take the worksheet and your acceptance criteria to a demonstration of Fleksa restaurant management software. Confirm the reporting workflow and any manual steps before buying.
Frequently asked questions
Is higher sales per open hour always better?
No. A higher rate can accompany lower total sales. Review the sales lost during removed hours and the relevant costs before deciding whether the schedule is better for the business.
Should a break between lunch and dinner count as open time?
Not if the restaurant is closed to the business included in the comparison. Remove the break from the denominator and use the same rule for both periods.
Can I compare a week with reduced hours to the same week last year?
You can, but show both total sales and open hours, and account for differences such as weekday placement, holidays and promotions. A same-weekday comparison across several completed weeks can provide useful context.
