The higher sales total gives you something to celebrate. Then you look at what the business has left, and the month feels different. You were busier. More customers bought. Somewhere between making the sale and finishing the work, much of the increase was spent.
What could the higher total be covering up?
Consider this invented example of a service business. The figures are illustrative, and the two columns cover the same length of time. Direct delivery costs include the materials and paid labor used for those jobs. The remaining expenses are grouped separately, so a dollar is counted only once.
| What the report shows | Last month | This month |
|---|---|---|
| Revenue from first-time customers | $12,000 | $20,000 |
| Revenue from returning customers | $8,000 | $6,000 |
| Total revenue | $20,000 | $26,000 |
| Direct costs of first-time customer work | $8,000 | $16,000 |
| Direct costs of returning customer work | $4,000 | $3,000 |
| Money remaining after direct delivery costs | $8,000 | $7,000 |
| All other business expenses before tax | $5,000 | $5,000 |
| Profit before tax | $3,000 | $2,000 |
The business sold $6,000 more and earned $1,000 less in profit before tax. Looking only at the revenue total would miss that change.
First-time customers brought in an additional $8,000. Delivering their work also cost an additional $8,000. The business kept $4,000 after the direct costs of that work in both months, despite the increase in sales.
Returning customers bought $2,000 less. Their delivery costs fell by $1,000, leaving the business with $1,000 less from that work. Together, those changes reduced what remained after delivery from $8,000 to $7,000. The other expenses stayed the same, so the reduction carried through to profit.
Now you have two specific places to look: what made the new work more expensive to deliver, and what happened with the returning customers.
Which of those costs could you have avoided?
Continue the invented example. When the owner checks the new-customer jobs, $2,000 of the $16,000 in direct costs turns out to be labor spent correcting work. The crew had started with incomplete instructions and had to return. Those correction costs are included in the table; they are part of what reduced the money left from the sales.
Paying to correct work you have already paid to complete is a specific expense to investigate. You can look at what was missing before the job began, who had that information, and how it could reach the people doing the work in time. The amount you can prevent depends on what caused the corrections and what it takes to change the process.
The returning-customer figure needs its own explanation. A regular customer's next purchase may have moved to the following month. Or a customer may have been waiting for a response that was missed. The first situation changes the timing of revenue. The second gives you a follow-up problem to address. Their totals could look the same until you examine what happened.
Looking at the parts lets you distinguish work that became more expensive, sales that moved to another period, and a mistake that cost the business money. Each calls for a different decision.
What can you check in the report you already have?
Start with two comparable periods. Put the revenue from one service or customer group beside the direct costs of delivering that work. Then account for the other business expenses before calling the amount left profit. Use the same categories in both periods so you can follow what changed.
If you'd like to try this, choose one area where costs rose faster than revenue. Your first step is to trace that cost increase to the jobs or expenses behind it. Write down the first specific cause you find and what you need to check before changing anything.
That gives your next decision a firmer basis. You can see where the additional work is paying you, and where it needs attention before you sell more of it.
