Why carpentry pros choose Bit & Grain.

From a grandpap's woodshop to your job site

Bit & Grain's founder grew up in his grandpap's woodshop and spends weekends on volunteer build sites. The tool ships features that match how carpentry work actually flows, not abstract project-management theory.

One tool for the office and the field

Quote work, schedule the crew, log time on site, and close out invoices, without bouncing between Jobber, QuickBooks, and a spreadsheet. Owner-operators and small crews running 1 to 5 person businesses get the same surface as bigger shops.

AI handles the receipt + materials grind

Grain AI scans receipts, logs mileage, and helps you keep job materials accurate without manual data entry, so you can spend the day swinging a hammer, not chasing paperwork.

How a carpentry contractor uses Bit & Grain on a real project.

Mike runs a three-person carpentry crew in the Pacific Northwest. Here is how a typical deck framing and trim project moves through Bit & Grain from the first call to the final payment.

  1. 1

    Estimating at the site visit

    Mike walks the yard, measures the deck footprint, and opens Bit & Grain on his phone. He builds the estimate on the spot: linear feet of decking material, joist spans, post hardware, and labor. The estimate goes to the client as a link in under five minutes. The client approves from their phone later that evening.

  2. 2

    Logging the lumber-yard run

    The morning of demo day, Mike stops at the lumber yard and picks up framing materials. He snaps a photo of the receipt in the Grain AI chat. The AI reads vendor, total, and each line item, and asks which job to assign it to. Two taps, and the purchase is on the deck job. No manual entry, no forgotten receipts in the glove box.

  3. 3

    Handling a mid-project scope change

    Halfway through the frame, the client wants to add a pergola. Mike pulls up the job in Bit & Grain, creates a change order with the added labor and materials, and sends it through the client portal. The client approves it from their kitchen while Mike is still on the job site. The change order automatically rolls into the final invoice so the billing is exact.

  4. 4

    Closing out and invoicing

    The last day of finish work, Mike opens the job summary and reviews actual materials versus estimated. He logs the final mileage for the project by telling Grain AI the start and end addresses, and it calculates the IRS-rate deduction. He converts the estimate to a final invoice in two clicks, the client pays via Stripe from their phone the same evening, and the job is closed. Total time on admin: under 20 minutes for a two-week project.
