What a real P&L tells us about a service business.

Most service-business owners read their P&L the same way. Once a quarter, a PDF arrives from the accountant. They look at the bottom line, decide whether they're up or down on last year, and put it in a drawer. The P&L was prepared for a tax purpose; it's used as a tax document.

We read the P&L looking for the row that's bleeding. We don't care about the bottom line first; we care about the line items that hide a leak the operator can fix.

The first place we look is the gap between revenue and direct costs by category. If you're a salon and your colour services revenue is up 18% but your colour-product cost is up 26%, something is wrong with how stock is decremented per service, and the leak is sitting in the gap. We've seen this exact pattern five times.

The second place is staff costs as a percentage of bookable hours, not as a percentage of revenue. If your stylist on chair four is paid the same as your stylist on chair one but bookable-utilisation is 41% and 78%, you have a price-list problem or a marketing-feed problem, not a hiring problem. The P&L can't tell you that on its own — but it can tell you when total staff cost is drifting away from total revenue, which is the canary.

The third place is supplier price drift. Most operators sign a supplier deal in year one and don't renegotiate. If your supplier line item has crept from £4,200 to £5,800 a month over twenty-four months and your covers haven't moved, that's £1,600 a month of margin you can recover with a Tuesday phone call.

The lines that don't matter, on a first read: marketing spend (until you have attribution wired), professional fees, software subscriptions under £200/month. They matter eventually; they're not where the leaks are first.

The audit doc we ship has all of this on a single sheet, with the operator's actual numbers in the columns and the leak rank in the rightmost column. It's the most important document we produce in the first two weeks.
