Joist made estimating and invoicing from a phone normal for a generation of contractors, and its reviewers name the ceilings: the QuickBooks sync moves clients and invoices but not the job-level detail real job costing needs, multiple users on one account is a struggle, and the features worth paying for keep migrating up the price ladder. Working from the documents Joist produces, each ceiling becomes a contained build. Five, pictured.
The job-level detail the sync leaves behind
Job costing dies when invoices land in the books as a lump. A bridge carries full line items into QuickBooks tagged by job, matches deposits to their estimates, and asks about an unmapped item exactly once.
Invoiced is not earned · this board knows the difference
Joist shows what you billed. A profitability board joins each job’s invoices with its actual costs and names the leaks: the second dumpster nobody billed, the repair price that predates the materials market.
You know when they open it · then the clock runs
Open notifications shouldn’t be a subscription feature you resent. Sending estimates through your own tracked lane, you see opens and view counts, and timers turn the three-views-and-silence signal into a scheduled call.
Every document, every photo, office-visible
One login on one phone means the office is blind. A vault mirrors every estimate, invoice, and job photo nightly into a searchable archive anyone at the office can read, which answers the multi-user complaint without sharing a password.
The Friday cash report
Sent, opened, unpaid, aging: one email at five o’clock Friday with the week’s money picture, assembled from the documents the phone already produced. It’s the same discipline the bigger platforms get in the Tradify list, sized for a truck-and-phone operation.
The common thread
Joist stays the pocket paperwork machine; the builds give it a back office. Each is a contained phase on a short calendar, and the QuickBooks bridge is the one your accountant requests by name.
