Why GCs choose Bit & Grain.

GC complexity without enterprise pricing

Buildertrend, Procore, and CoConstruct charge $300-1000+/mo per user for the GC workflow. Bit & Grain ships subs, change orders, materials, and client portal at $29/mo, priced for owner-operators and small GC crews running 1 to 5 person businesses, not branch-level enterprises.

One tool for office, field, and customer

Quote work, schedule subs, track daily logs, manage change orders, AND keep the owner in the loop, without bouncing between Buildertrend, QuickBooks, a shared spreadsheet, and email. Everything lives in one operating system.

AI keeps the receipts and paperwork off your truck

Snap a photo of any supplier or sub-invoice receipt and Grain AI logs vendor, amount, items, and maps each line to the right project. Less time on paperwork, more time managing the build.

How a small GC uses Bit & Grain to run a full residential addition.

Chris runs a three-person GC operation in the Southeast, handling residential additions and remodels. Here is how a master bedroom and bathroom addition moves through Bit & Grain from the first call to the final lien waiver.

  1. 1

    Bidding the job with a line-item estimate

    Chris walks the house with the homeowner and builds the estimate in Bit & Grain: framing labor, electrical sub, plumbing sub, HVAC sub, drywall, flooring, trim, and materials allowances. Each trade line shows the sub cost and the markup separately. He sends the estimate through the client portal. The homeowners review it that evening, ask one question about the flooring allowance, and approve it the next morning with a digital signature.

  2. 2

    Scheduling subs and keeping their documents on file

    Chris sets up the electrical and plumbing subs in Bit & Grain with their license and insurance documents attached. He schedules each sub to their phase: rough-in electrical week three, rough-in plumbing week four. When the electrician renews their insurance, Chris uploads the new certificate. Both subs show up on the job timeline with their scheduled windows visible.

  3. 3

    Handling a mid-project allowance overage

    The homeowners pick flooring that runs $2,800 over the allowance. Chris creates a change order in Bit & Grain with the overage amount and sends it for signature. The homeowners approve it digitally the same day. The change order locks in, the total contract amount updates, and the milestone billing schedule adjusts automatically.

  4. 4

    Milestone invoicing and final closeout

    Chris sends milestone invoices at foundation, rough-in, and drywall complete, each through the client portal with a Stripe payment link. The homeowners pay each milestone the same day. At project closeout, the final invoice pulls in the original scope plus the flooring change order. The homeowners pay, Chris marks the job complete, and the job record closes with every document, receipt, and signed change order attached.
