The problem
Most small shops find out they underbid a job type at tax time, if at all. The data is there (quoted hours in the quote, actual hours in timesheets), but comparing them job by job is tedious enough that nobody does.
What Cowork does
- A weekly task reads jobs completed last week from Jobber, with quoted line items.
- It reads logged hours for those jobs. Jobber timesheets are available through Composio's Jobber toolkit, if available; otherwise from a timesheet export the office drops in Drive.
- It compares estimated and actual labor per job and groups the results by job type.
- Once a month it emails the owner the job types that ran over by more than 15 percent, with examples.
Where the draft lands
A monthly email and a job-costing sheet.
What stays with you
Changing prices and talking to crews about why jobs ran long.
September, labor over estimate by more than 15%:
EV charger installs: 6 jobs, quoted 4.0 hrs avg, actual 5.3 hrs (+33%). Long garage runs on 4 of 6.
Service upgrades: 3 jobs, +18%.
On target: fixture installs, troubleshooting.
Watch-outs
- Timesheets are often incomplete. Treat early results as rough until crews log time consistently.
- Materials overruns need QuickBooks bills matched to jobs, which is harder. Start with labor.
Questions owners ask
Does it work with ServiceTitan?
ServiceTitan's data is richer and available through Composio. The idea is the same.
Will it change my prices?
No. It shows where the numbers are off.
