Free Project Bid Templates & Cost Estimator for Contractors

Winning construction work usually comes down to two things: getting an accurate bid number, and getting the bid document in front of the customer fast — before a competitor does. Here's how to do both without a spreadsheet you rebuild from scratch every job.

The cost estimator

FLYNT Sheets includes a Project Cost Estimator template with real, live formulas: materials cost, labor cost, and equipment rental roll up into a subtotal, with overhead and contingency percentages applied on top to produce a total bid price. Change any input — materials came in higher, labor hours changed — and every downstream number recalculates automatically.

The bid document

FLYNT Docs includes a Construction project bid AI template — describe the job and get a formatted bid document draft, so you're editing and finalizing instead of writing the whole thing from a blank page for every project.

Change orders

Scope changes mid-project are constant in construction, and documenting them properly matters for getting paid for the extra work. There's also a change order AI template for exactly this — generate a clear, formal change order document instead of an email thread that's hard to reference later.

One number, one document

The estimator and the bid document don't have to be disconnected — run the numbers in the cost estimator, then use those same figures when generating the bid document, so the price on the page actually matches the math behind it. It's free to start with FLYNT, and both the calculator and the AI templates live in the Sheets and Docs dashboards.
