Construction and Contractor Job-Costing Bookkeeping

1. 1

   Learn job costing cold

   Master tracking income and costs per project so an owner can see the profit on each job. Job costing is the hard skill at the center of construction bookkeeping, and it is precisely what most bookkeepers cannot do.

2. 2

   Handle the construction specifics

   Understand progress billing, retainage, change orders, and coding materials, labor, and subcontractors to the right job. These mechanics are why contractors need a specialist and pay one.

3. 3

   Know the compliance edges

   Be aware of subcontractor 1099s, and for some clients, certified payroll and lien-related paperwork. You do not have to file everything, but knowing the landscape makes you the trusted hub, and you refer the rest out.

4. 4

   Pick your contractor type

   Specialize in a trade or size: remodelers, custom home builders, or specialty subs like electricians. A defined niche makes your setup repeatable and your marketing precise.

5. 5

   Price for the complexity

   This is skilled, high-value work, so charge accordingly with monthly packages (often $500 to $2,000) that include per-job profit reporting. The visibility you provide is worth far more than basic bookkeeping.

6. 6

   Deliver the job-profit report

   Give owners a monthly report showing which jobs made money and which lost it. That single report changes how they bid future work, and it is the reason they will never leave you.

Best for: Advanced bookkeepers who want a hard, well-paid niche with loyal clients
