Decide whether the work is genuinely additional
Compare the add-on with the package checklist. If the base package already includes a task, do not sell the same task again under another name.
If nearly every customer needs an add-on to get the advertised result, reconsider the package description. An attractive starting price can damage trust when the expected total changes at every inspection.

Estimate the extra resources
Some work is better priced after inspection than with a universal flat fee. Explain why assessment is needed rather than giving a low number you expect to revise.
- Additional person-hours and required skill.
- Materials and equipment use.
- Setup or protective steps beyond the base service.
- Calendar time and the effect on later jobs.
- Limits on the result you can safely promise.

Use a clear approval message
This is an operational communication example. Your customer terms and applicable law determine how authorization should be documented.
The booked package covers [scope]. We found [condition] that would require [additional work]. The additional price is [amount], and it adds approximately [time]. The expected result and limits are [description]. Would you like us to proceed, keep the original scope, or discuss another option?

Preserve the decision on the job
Record the approved service line, vehicle, price, and relevant customer expectation. A technician should not have to interpret a chat reaction as approval for a charge.
If the customer declines, record that neutrally. Do not imply incomplete work when the declined task was outside the purchased scope.
Review add-ons as separate work
Compare estimated and actual time by add-on. Repeated overruns may mean the condition categories are too broad or the sales description promises an unrealistic result.
Avoid measuring success only by add-on revenue. Rework, complaints, and schedule disruption can outweigh the extra sale.
The practical takeaway
Sell additional work with a clear scope, price, time allowance, and explicit customer decision.
