Your price book, ready in minutes
Start with your own items and prices. For example, a builder might add:
| Room addition (per sq ft) | $250 |
| Foundation pour | $8,000 |
| Framing package | $15,000 |
| Roof tie-in | $4,500 |
| Electrical rough-in | $3,500 |
| Drywall & finish | $6,000 |
Example prices only — you set yours. Import your list from a spreadsheet in seconds.
Example: Primary bedroom addition at the back of the house
A growing family wants a 400-square-foot bedroom with a bathroom. It is a months-long job with a foundation, framing, roof tie-in and every trade inside.
| Room addition (per sq ft) × 400 | $100,000 |
| Foundation pour | $8,000 |
| Roof tie-in | $4,500 |
| Total | $112,500 |
| Deposit to start (20%) | $22,500 |
Break the job into phases on the estimate and record each draw as a payment. Expenses with receipt photos keep the budget honest week after week.
An example to show how it works — prices and steps are yours to set.
What customers ask a builder
How long does an addition take?
Often several months. Your schedule shows each phase so the family can plan.
Will it match the rest of the house?
Note the siding, roofing and window choices on the estimate so the expectation is written down.
How do payments work?
Usually a deposit and draws at milestones. Each one is recorded on the invoice.
Tips for your builder business
- Milestone payments protect your cash flow — never front a whole phase.
- Keep a running photo record for inspectors and for the homeowner.
- Track every subcontractor bill as an expense; additions have dozens of them.
One path, start to paid

Questions home addition builders ask
Can customers pay a deposit?
Yes. Set a deposit on the estimate; the customer pays it by card and approves the job at the same time.
Can a job last several days?
Yes. Set how many days a job takes and it shows on each day of the schedule.
