How do I track job costs against the quote?
Short answer
Log labor hours, materials, and subcontractor costs against the job as they happen, then compare that running total to the original quote in real time instead of waiting for a final invoice to find out margin disappeared. TactStack shows the gap between quoted and actual cost on the job so overruns get caught while there is still time to fix them.
Before you start
- A quote with line items broken out by labor, materials, and subcontractor cost.
- A way for field crews to log hours and material use as work happens.
- Actual vendor costs for materials used on the job.
- A margin threshold that should trigger a review.
Step by step
- 1
Break the quote into cost categories, not one lump sum
Separate labor, materials, and subcontractor cost on the original quote instead of quoting a single flat number.
You cannot track an overrun in a category that never existed separately.
- 2
Set the budget per category on the job
Carry the quoted labor hours, material cost, and sub cost onto the job record as the target to measure against.
Actual cost only means something next to a number it is supposed to stay under.
- 3
Log labor hours as they happen
Have crews clock time against the specific job from the field instead of reconstructing hours from memory at week's end.
Hours guessed after the fact are always wrong, usually in the crew's favor.
- 4
Record material costs at actual price, not quoted price
Enter what materials actually cost from the vendor invoice, not the number originally estimated.
Price increases between quoting and buying are invisible until you log the real number.
- 5
Add subcontractor invoices to the job as they arrive
Attach each sub invoice to the job the day it comes in rather than batching them at the end.
A sub invoice sitting in an inbox is a cost overrun you have not seen yet.
- 6
Check the running total against the quote mid-job
Review actual versus quoted cost at least once while the job is still in progress, not only after completion.
A margin problem caught halfway through can still be managed. One caught after is just a loss.
- 7
Flag jobs that cross your margin threshold
Set an alert or a manual check for jobs where actual cost has eaten a set percentage of the expected margin.
The jobs quietly bleeding money are rarely the ones anyone thinks to check.
- 8
Review the final variance after closeout
Compare quoted to actual cost once the job closes and note what drove any gap for future quoting.
Every overrun is a pricing lesson if someone actually looks at it.
What good looks like
- Margin erosion gets caught mid-job instead of on the final invoice.
- Quotes get more accurate over time because real cost data feeds them back.
- Subcontractor and material overruns surface before they compound.
- Owners can see which job types consistently run under or over budget.
Common mistakes
The ways this goes wrong in money, and what to do instead.
Quoting in one lump sum instead of by category›
A single flat quote number makes it impossible to tell whether labor, materials, or subs caused an overrun.
Do this instead: Break every quote into labor, materials, and subcontractor line items.
Logging hours from memory at the end of the week›
Reconstructed hours are consistently inaccurate and hide real labor overruns.
Do this instead: Have crews log hours against the job from the field as they work.
Only checking cost after the job is finished›
A margin problem discovered on the final invoice can no longer be corrected by adjusting scope or crew time.
Do this instead: Review actual versus quoted cost at least once while the job is still active.
Letting sub invoices pile up before entering them›
Batching subcontractor costs at the end of a job hides overruns until it is too late to react.
Do this instead: Attach subcontractor invoices to the job the same day they arrive.
