Free Estimate Software for Contractors
Updated: 2026-09-22
Contractors lose jobs when quotes arrive late; and lose money when quotes are vague. Free estimate software for contractors should do three things fast: price the job clearly, send a professional PDF, and convert the approved quote into an invoice without rebuilding the line items.

Real contractor estimate example
Here is the kind of quote clients actually approve, not a feature list.
Job: Handyman Home Repair Demo · Customer: Taylor Demo · Orlando, FL
Terms: 25% deposit after approval (balance due on completion) valid 14 days
| Item | Qty | Rate | Total |
|---|---|---|---|
| Drywall patch labor | 2 | $75 | $150 |
| Interior door adjustment labor | 1 | $75 | $75 |
| Shelf installation labor | 2 | $75 | $150 |
| Repair materials and shelf hardware | 1 | $75 | $75 |
| Approved add-on | Cabinet handle installation | 1 | $75 | $75 |
| Estimate total | $525.00 |
What makes this usable as quoting software for contractors:
- Scope is readable in plain English.
- Labor and materials are separate lines.
- Add-ons are visible (the total moved from $450 to $525 for a reason).
- The same job can become an invoice after approval.

Who this is for
Free contractor estimate software fits crews that need speed more than enterprise job costing:
- Landscapers sending seasonal quotes
- Plumbers pricing service calls and fixture installs
- Roofers with per-square material breakdowns
- Drywall installers quoting sheets, mud, and labor
- Painters and handymen juggling small jobs
- Solo operators without an office admin
If you need deep job costing, purchase orders, and change-order profit tracking across many open jobs, see the fuller workflow guide: estimate software for contractors (job costing).

Estimate vs invoice (and why both belong in one tool)
| Estimate | Invoice | |
|---|---|---|
| When | Before the work | After a milestone or completion |
| Job | Win the work at a clear price | Get paid for what was approved |
| Core fields | Scope, labor, materials, terms | Invoice #, due date, amount due, payment instructions |
| QuickAdmin | Free: 6/month | Free: 3/month |
The win is conversion: approved line items become the invoice. That is how you stop rewriting the same job twice.
Trade examples (what to put on the quote)
Landscaper: mulch area, sod, tree trim, labor hours, seasonal notes. Recurring schedules and automatic payment reminders are paid-plan features (Free still covers the quote itself).
Drywall: sheets, mud, tape, waste %, labor hours, commercial vs residential notes. For software comparisons, see best drywall estimation software.
Plumber: labor, fixtures, pipe, callout fee, tax, parts markup. Templates save time on repeat service calls.
Roofer: per-square shingles, underlayment, flashing, cleanup, weather delay notes.
Painter / handyman: prep, coats, surfaces, small-repair bundles, approved add-ons as separate lines.
From free estimate to invoice
Once the client agrees:
- Open the approved estimate.
- Convert it to an invoice (adjust only what changed).
- Send PDF or share from QuickAdmin.
- Record payments and keep the balance visible.
- For open balances, use your invoice tracker or invoices list weekly.
Integrated pay-by-link and automatic overdue reminders are on Basic and higher; not Free. Free still lets you create, send, and track status within the monthly limits.
Limitations of free plans (and when to upgrade)
Free plans usually cap:
- Estimates and invoices per month
- Users and open jobs
- Automation (reminders, online payments)
Workaround on Free: use it for smaller jobs, one-off clients, or to prove the workflow before upgrading. Upgrade when you regularly hit 6 estimates or 3 invoices in a month, need multiple users, or want automatic reminders.
