A small job can use very little film and still occupy half a day. Loading, driving, checking in, protecting the room and closing out the work do not shrink in proportion to the glass.
A minimum charge should cover the job you are actually scheduling. It should also tell you when a small job is worth combining with another visit and when the apparent convenience is hiding a second trip.
Start with the time the job occupies
Count the time from preparation to completion, not just squeegee time. For a local service job, that may include:
- Confirming the scope and arranging access.
- Preparing and loading material and tools.
- Driving, parking and unloading.
- Site protection, installation and cleanup.
- Returning, putting equipment away and finishing the job record.
Some work is done by an office employee rather than the installer. It is still a cost. Keep separate rates if the costs differ, but do not leave the time out because it happened at a desk.
Travel with two people also has two labor costs. A one-hour round trip for a two-person crew uses two person-hours, plus the vehicle cost. Treating it as one hour in a labor calculation understates what the visit consumes.
A hypothetical minimum-charge calculation
Consider an easy-access job with 24 square feet of film. Assume one installer and no removal, unusual access or return visit.
| Activity | Hours |
|---|---|
| Preparation and loading | 0.35 |
| Round-trip travel | 0.90 |
| Protection and setup | 0.30 |
| Installation | 0.80 |
| Cleanup and loading out | 0.25 |
| Scheduling and closeout | 0.40 |
| Total | 3.00 |
For this simplified example, use the same $42 loaded hourly cost for all three hours. Assume $48 in material, $12 in consumables and $24 in vehicle-related cost allocated to the job.
Labor is 3 × $42 = $126. Total direct cost is $126 + $48 + $12 + $24 = $210.
At an illustrative 40% gross margin, the price needed is $210 ÷ 0.60 = $350 before any applicable tax. That is $14.58 per installed square foot, rounded to cents, even though no one selected a $14.58 square-foot rate.
The $350 result is not a recommended minimum for every shop. It follows from invented costs and one set of conditions. Change the travel, labor cost, material or required margin and it changes. Its purpose is to show why a minimum comes from the visit rather than the pane area alone.
Give the minimum a defined scope
A minimum is easier to use consistently when the shop knows what it includes. Define the normal service area, working hours, access conditions and type of work covered by that minimum.
A nearby ground-floor bedroom and a downtown tenant space may have the same glass area. Paid parking, a freight elevator reservation, loading restrictions and a security check-in can make them different visits.
You can show a single job price to the customer while retaining the detailed calculation internally. The important part is that the quoted scope matches the assumptions. A broad statement that every small job costs the same can leave the crew carrying costs nobody intended to include.
Do not make the minimum an automatic substitute for checking material. An unusual product, special order or large offcut requirement can exceed the material assumption even on a small opening.
Calculate a second trip before promising one
Suppose the same hypothetical job needs another visit because one room will not be available on the first day. Assume the extra trip requires:
- 0.25 hour of preparation.
- 0.90 hour of travel.
- 0.25 hour of setup.
- 0.50 hour on the remaining window.
- 0.20 hour of cleanup.
- 0.15 hour of administration.
That totals 2.25 hours. At $42 per hour, labor costs $94.50. Add another $24 for the vehicle and $6 in additional consumables. The extra direct cost is $124.50, assuming the original material allowance already includes the remaining piece.
At the same illustrative 40% gross margin, the extra visit needs $124.50 ÷ 0.60 = $207.50 in revenue. A promise to return for “just that last pane” has added a visit worth more than half the original job price.
If the visit is required by the original installation plan, include it before the job is accepted. It does not become free merely because the hands-on work is short.
Keep three types of return visit separate
A planned second visit belongs in the original scope and schedule. Examples include customer-requested phases or a known access restriction.
Additional work requested later needs its own scope and price. You may choose to combine it with another route, but confirm the timing rather than implying an open-ended promise to return whenever convenient.
A workmanship callback belongs in your quality and warranty process. Do not quietly reclassify your own corrective work as a customer-requested trip charge. Track its cost internally so it informs training and the business's callback allowance.
A manufacturer-related claim may follow another process. Verify the applicable coverage before promising that someone else will pay for labor, travel or replacement material.
A route day can lower cost if the route is real
Combining two small jobs can reduce driving and loading duplication. It does not remove either job's protection, cleanup or customer coordination.
In a hypothetical route arrangement, suppose the combination saves 0.60 labor hour and $12 of vehicle cost compared with two separate visits. At $42 per hour, the total direct saving is $37.20. At a 40% gross margin target, that can support $62 less combined revenue while retaining the same margin percentage: $37.20 ÷ 0.60.
That is a defined saving. Discounting both jobs by $100 because they are in the same neighborhood would be a different business decision.
Confirm both customers' windows of availability before relying on the route. If one cancels, know whether the remaining job still meets your minimum. A flexible route price can be useful, but it needs a schedule the customer has agreed to.
Review minimums using completed jobs
After several small jobs, compare estimated and actual occupied time. Separate the difference caused by travel from the difference caused by installation. A traffic-heavy service area may need a different approach from a shop whose small jobs consistently take longer inside the building.
The useful test is whether the minimum covers the visit under the conditions you promised. When it does, small jobs can fit the schedule without depending on the next large job to absorb their cost.
