Plumbing Callbacks and Free Re-Clears: Charge Them to the First Job

Why plumbing callbacks disappear from job costing

The mechanics are innocent. The customer calls back, the CSR books a new job, the job carries a $0 invoice or a “warranty” job type, and nothing on it points at the original visit. The first job keeps its full margin in the report. The recall shows up only as an hour of labor with no revenue, spread across the month, where it looks like ordinary slack.

An owner who knows the cost may carry it on purpose. One contractor wrote on the Heating Help forum, “we don’t charge for call backs,” and described setting aside 1% of income in a reserve account for the visits that come back. That is a reasonable self-insurance habit. It is also a sign that the callback cost is managed as a lump, not as a property of the job types and the techs that cause it.

When recalls are not tied to the first visit, three questions cannot be answered: which job types carry the most recalls, which techs’ work comes back, and whether the guarantee is priced into the work it covers.

Linking every recall to the job that caused it

The fix is a link, not a report. If the field-service software has a recall or warranty field that points at the original job, use it every time; if it does not, a note carrying the original job number does the same work.

• At booking, the CSR asks one question on every drain, leak or water-heater call: “Has anyone from us been out for this in the last 90 days?”
• If yes, the new job carries the original job number and a recall job type, never a fresh service call.
• The tech who returns records a cause in one of three words: same cause (the first clear did not hold), new cause (a different problem), or customer cause (grease, wipes, or a repair the customer declined).
• The original tech’s name stays on the record, for coaching, not for blame.
• Once a week, one named person — the service manager or the office manager — reviews the recall list against the jobs it points at.

After a month, the shop has something it did not have before: recalls per job type, with causes, from its own records.

Paying the tech for the recall hour

How the returning tech is paid for a recall is a pay-plan decision with legal edges, and the edges are worth knowing before the conversation. Where techs are paid by the piece — a flat amount per task — the federal overtime rule for pieceworkers at 29 CFR 778.111 builds the regular rate from all of the week’s earnings, including “any sums paid for waiting time or other hours worked,” divided by every hour worked in the week. A recall hour paid at zero still counts as an hour worked, which lowers the regular rate and moves the week toward the 40-hour line.

Charging a recall back against the original tech’s pay is a step further, and state wage laws can restrict deductions from pay. Commission plans fall under other sections of the same federal rules. Before any of these becomes a policy, it belongs with the company’s employment attorney or payroll provider. The operational point stands either way: the recall hour has a cost on payroll, and it belongs on the first job’s cost, not in the month’s overhead.

Pricing the guarantee instead of absorbing it

A drain guarantee is a product. It wins work, and it has a cost that can be counted per job type once recalls are linked. Treat it the way any product is treated: write the terms, count the cost, and put the cost in the price.

Illustrative example, not a client: the shop’s linked recalls show one same-cause re-clear for every ten main-line clears last quarter, at about $106 a visit before burden. Spread across the ten clears, the guarantee costs about $10.60 per main-line clear. That amount belongs in the main-line price — or in a longer, paid guarantee option offered next to the standard one.

• Write the terms on the ticket: the period, which line was cleared, and what is not covered — grease, wipes, or roots the camera found and the customer chose not to repair.
• Record the camera finding and the recommendation on the first visit. A recall caused by a declined repair is then a new, paid visit under the written terms, and the open sewer estimate gets a second call instead of a free re-clear.
• Review the guarantee price each quarter against the linked recall count, the way the pricebook is checked against supply-house costs.

A thirty-minute callback count from last quarter

No new software is needed to see last quarter’s callbacks. One export and a sort will do.

• Export every job from the last 90 days with its address, job type, tech, invoice total and date.
• Filter the jobs invoiced at $0 or marked warranty, recall or callback.
• Match each one by address to a paid job at the same address in the 90 days before it.
• Tally the matches by job type and by the tech on the original visit.
• Multiply the count by the shop’s own cost per truck roll.

The result is a callback rate per job type and a quarterly dollar figure, both from the company’s own records. A shop whose matches cluster in one job type has found a pricing question; a shop whose matches cluster under one tech has found a training question. Neither is a reason to drop the guarantee.

When not to change anything

If the count turns up a handful of recalls in a quarter, the guarantee is cheap, and changing the price or the terms may cost more in goodwill than it saves. If the guarantee is what wins the drain work against competitors, keep it and price it; the point is to know its cost, not to remove it. If the recalls trace to one tech’s technique, that is a training job — the same procedure, the full line cabled, the water run before leaving — not a pricing project. And in a one- or two-truck shop where the owner does or checks every clear, the owner already knows which jobs come back.

Callbacks are one of several places a plumbing company’s money can leave after the work is done; open sewer estimates, trench extras never invoiced and finished tickets waiting for a PO number are others. Our Revenue Review counts each of them from the shop’s own records: two weeks, read-only, ending in a written report with a monthly dollar figure wherever the records support one. Nobody here plumbs, and the Review gives no code or legal advice. The free 20-minute call says plainly when the Review is not worth it.
