Grading Your Customers A, B, C, and D
Why this matters
Not all customers are equal, but most shops treat them as if they are, giving the same time and the same prices to the customer who refers three neighbors a year and the one who fights every invoice. Grading your base sorts that out. It tells you who to protect, who to grow, who to fix, and who to let go, so your best energy goes where it earns the most.
The two axes that set the grade
Grade on two things together, not one:
- Value: revenue, yes, but also referrals, repeat work, and steady scheduling. A mid-size customer who refers others and pays on time is high value.
- Cost to serve and hassle: slow pay, scope fights, callbacks driven by their behavior, disrespect to staff, chronic no-access. High hassle drags the grade down even when revenue is decent.
A customer is graded on value minus hassle, not revenue alone. This is the whole point: a high-revenue, high-hassle customer can grade below a modest, easy one.
The grade table
| Grade | Looks like | What to do |
|---|---|---|
| A | High value, low hassle. Pays on time, refers, respects the crew, decides cleanly | Protect fiercely. Priority scheduling, first call on new capacity, small extras |
| B | Solid and steady, maybe not a referrer, but no trouble | Keep happy, look for room to grow them toward A |
| C | Break-even. Fine revenue but real friction, or easy but low value | Manage the friction. Firm terms, no discounts, watch the trend |
| D | Costs more than they pay in money, time, or morale | Fix the terms or let them go |
How to actually run the grading
- Pull your customer list and score each on the two axes. A simple high, medium, or low on each is enough to start.
- Do not overthink the tools. A spreadsheet and one honest afternoon beats a perfect system you never build.
- Ask the crew. Your techs know which addresses they dread. That is grading data the office does not see.
- Regrade a couple of times a year. Grades drift. An A that stops paying is a C now, whatever they were last year.
What each grade changes
The grade is only worth assigning if it changes how you treat the customer:
- A and B get your scarce good stuff: the tight morning slots, the tech they like, the benefit of the doubt on a judgment call.
- C gets structure, not charity: no price breaks, deposits where warranted, and a close eye on whether they are trending up to B or down to D.
- D gets a decision: either reprice and re-term them into at least a C, or fire them cleanly so their slot goes to someone better. See related: Fire This Customer or Keep Them: A Decision Tree.
Do not confuse a grade with a person
Grading is about the relationship, not the human being's worth. A kind, well-meaning customer can be a D to serve, and a blunt, demanding one can be an A who pays well and sends referrals. Grade the way the account actually runs, keep the grades inside the shop, and use them to aim your effort, not to judge anyone.
