Five numbers that tell you if your store had a good week

Monthly P&L is too slow. By the time you see a bad month, it's been bad for four weeks, and you've already paid for it. If you want to run a tight store, you need a weekly pulse check — five numbers, ten minutes, every Monday morning.

Not twenty metrics. Not a dashboard with every KPI your POS can spit out. Five. The right five. Here they are.

1. Inside sales per labor hour

Take your inside sales for the week (everything that isn't fuel) and divide it by the total labor hours you ran. That's your inside productivity number.

This is the fastest way to see if you're overstaffed or understaffed. A good independent store in most markets lands somewhere between $60 and $110 per labor hour, depending on foodservice mix and lottery volume. What matters more than the absolute number is the trend — if last week was $82 and this week is $71, something changed. Maybe you added a shift. Maybe foot traffic dropped. Maybe someone's stealing hours.

Pull it weekly. Track it. It will tell you more about your store than almost anything else.

2. Fuel margin per gallon

This is cents per gallon, after credit card fees, after shrinkage, after any promo programs. Not your street margin — your actual, money-in-the-pocket margin.

The trap with fuel is that operators watch the street price and the wholesale price and assume the gap is the margin. It isn't. Between you and that gap are credit card interchange (around 2.5% on a $3.79 gallon, so ~9.5 cents), any drive-offs you ate, any meter variance at the pump, and any under-deliveries on the last load.

If you can't tell me your real fuel margin per gallon within a half-cent, you don't know your fuel business. Most independents are losing 3-8 cents a gallon to leaks they haven't measured.

3. Inventory variance (dollars, not percent)

Every week, do a variance check on your top ten SKUs by dollar volume. Not the whole store — the top ten. Expected inventory minus actual inventory, times cost.

Express it in dollars, not percent. "2.3% variance" sounds fine. "$847 variance" sounds like the problem it is. $847 a week is $44,000 a year. That's more than most independents' net margin on a single store.

If you pick the right ten SKUs (high-volume, high-theft, high-cost), you'll catch 80% of your shrink problem by auditing 5% of your inventory. The other 90% of the SKUs can wait for the monthly count.

4. Credit card fees as a percent of inside sales

Pull your merchant statement. Take total card fees divided by total card sales for the week. You're looking for a number that should be flat.

When this number moves, something's wrong. Either your processor is quietly changing your rates (it happens more than you'd think), your mix shifted toward more debit or more credit (which affects blended rates), or you've got a downgrade problem — transactions that should be qualifying at the low rate are getting bumped to mid-qualified or non-qualified tiers because of how they're being run.

Independents get quietly bled on card fees more than on almost any other line item, because nobody's watching the statement. Watch it weekly. If the number moves more than 0.15% in either direction, call your processor.

5. One qualitative number: "did I get a call I shouldn't have gotten?"

This one isn't from a spreadsheet. It's from your memory.

Count how many times this week an employee called you with a question that had a clear answer somewhere — in a manual, in a training doc, in the opening checklist, in your head. "Where's the key for the safe?" "How do I void this transaction?" "The lottery machine is asking for a code." Every one of those calls is a documentation gap, and every documentation gap costs you attention, which is the only resource that doesn't scale.

If the number is zero, your store runs itself for a week. If it's twelve, you don't own a store — you own a job that calls you on the weekends.

How to actually do this

Ten minutes, Monday morning, same time every week. Pull the five numbers into the same spreadsheet or notebook you used last week so the trend is visible. Write one sentence about what changed. Move on.

You don't need dashboards. You need the habit of looking.

Five numbers, ten minutes, every Monday. That's the pulse.
