When to Eat the Difference and When to Re-Quote

Why this matters

The extra work is real and someone is going to pay for it - you or the customer. Absorb every overage and you run jobs at a loss while feeling generous; re-quote every one and you nickel-and-dime your way to a reputation as the shop that always comes in over. This is a money and relationship decision, separate from the operational question of whether to stop the job. Getting it right protects both your margin and your customer list, because the answer is not always the same and the tell is usually whose fault the overage is.

Start with fault, because it decides most cases

The first and heaviest factor is why the extra cost exists.

• Your estimating miss: you could have caught it on the walkthrough and did not. Lean hard toward eating it. A customer who agreed to a price should not pay for your oversight, and the goodwill of "that one is on me" buys more than the overage costs.
• A genuinely hidden condition: no reasonable inspection would have revealed it (behind the wall, inside the sealed system, under the slab). This is legitimately re-quotable. You quoted what you could see; you cannot pre-price the invisible.
• Customer misrepresentation: they knew and did not tell you, or actively hid it. Re-quote, and document what changed. You are not obligated to absorb a cost you were maneuvered into.

Fault alone resolves a large share of these. The rest is sizing.

Then weigh size against the relationship

Once fault is clear, two more factors tune the call.

• Size of the overage relative to the job: a trivial overrun is often cheaper to absorb than to explain, invoice, and defend. A material one has to be a re-quote or the job goes underwater.
• Value of the relationship: a repeat customer, a maintenance-plan member, a source of referrals earns more slack than a one-time call. Eating a marginal overage for a customer worth many future jobs is an investment, not charity.

The decision at a glance

Do the goodwill math, do not just feel generous

Eating a difference is a marketing spend, so treat it like one. A small absorption that turns a nervous customer into a loyal one and a five-star review is a bargain. Absorbing a large overage on a one-time job with no referral potential is just a loss you are calling kindness. Ask what the absorption actually buys before you swallow it. If the answer is "nothing but the momentary avoidance of an awkward conversation," you are eating it for the wrong reason.

Watch the precedent you set

What you absorb quietly, a repeat customer may come to expect. If you eat a difference, say so plainly and frame it as the exception it is: "This one is on the house because I missed it - normally a change like this would be a separate charge." Silent generosity that becomes an assumed baseline costs you on every future job. Name the gift so it stays a gift.

Never let a single job teach you nothing

However this one lands, close the loop with yourself. A re-quote means your walkthrough or your pricing missed something catchable - fix the checklist. An absorption means you gave margin away - decide if it was worth it. The shops that bleed on overages are the ones that keep making the same estimating miss and keep eating it, month after month, calling it customer service.
