Joist Invoice & Estimate App is a business tool from Joist Software Inc. aimed at tradespeople who quote and bill for work themselves. It has been on Google Play since April 2014 and now sits past a million installs with a 4.6 average from more than 13,000 ratings. The pitch is straightforward: build estimates and invoices on site, keep each job's details together, and take card payments without a trip to the bank.
What makes it worth a look is the combination of quoting, scheduling and payment collection in one place. A contractor who writes estimates by hand, texts photos to clients and chases checks separately is doing three jobs badly. Joist is built to fold those into a single record per customer, which is the sort of consolidation that saves time precisely because nothing has to be re-entered.
The app is free to download and free to estimate with, carries no ads, and offers in-app purchases.
Trades that fit this app best
The developer lists a long roster of trades: general contractors, handymen, electricians, plumbers, builders, landscapers, arborists, roofers, painters, carpenters, HVAC technicians, flooring installers, remodelers, deck builders, drywallers and lawn care crews. That is broad, but the common thread is work that is quoted per job, performed at a customer's property, and billed once the work is done or in stages.
If your day involves driving between sites, meeting homeowners, and writing up what needs doing before you can price it, the app's shape makes sense. The same goes for a small crew where one person handles the paperwork. Solo operators who currently do estimates at the kitchen table in the evening are the clearest fit, since the app is designed to let you finish the quote before you leave the driveway.
Construction estimators who price larger projects may find the material and labor item lists useful as a starting point, though the emphasis throughout is on speed rather than detailed takeoff work. Anyone whose jobs are priced by the hour and billed monthly, or whose customers are other businesses on purchase-order systems, will have less to gain from the on-the-spot estimate flow.
Quoting and billing without the paperwork
At its core the app creates estimates and invoices. You build them by selecting from a list of materials and labor rates you use often, which the app keeps for reuse, and it calculates material and labor costs as you go. Estimates can be converted into invoices once the work is approved, so the same line items carry through without retyping.
Templates can be customized with your company details and logo, and you can add a personal message for the client. Finished documents can be previewed, printed or emailed on the spot, which matters if you want to hand someone a quote while you are still standing in their kitchen. Photos can be attached to estimates and invoices, and contracts can be attached with signatures collected on the spot.
On the money side, the app accepts credit card payments from clients directly, which the developer pitches as a way to stop driving around to collect and deposit checks. It also tracks customer payments and how much you are owed, so outstanding balances are visible rather than remembered. You can set tax rates and send your figures to accounting software.
Keeping every job in one place
Each job holds client details, estimates, invoices, notes and photos, all connected, so you can see where the work stands without digging through texts or paper. Client records can be created, organized and stored, and accessed when you are out on the road. That is the organizational spine of the app, and it is the feature most likely to change how a small operation runs.
Scheduling is handled through a calendar view of upcoming jobsite visits, which the developer presents as a way to spot conflicts and plan the workday. Active jobs are tracked so you can tell at a glance what is in progress, what has been quoted and what has been paid.
Because the app is cloud-based, the same information is reachable from any device and from the web.
What it costs and what the subscriptions cover
There are no ads. In-app purchases are offered in the form of two subscription tiers, Joist Pro and Joist Elite, each available monthly or annually.
Subscriptions renew automatically unless auto-renewal is switched off at least 24 hours before the current period ends, and settings can be managed in the Play Store at any time. The free tier is the place to start, and from there you can judge whether the paid levels are worth it for the way you work.
Support is available by email at [email protected] or through in-app live chat, seven days a week, which is a reasonable arrangement for a tool that people rely on while standing in front of a customer.
How it compares with the alternatives
The realistic alternatives fall into a few groups. One is general accounting software, which handles bookkeeping, payroll and tax filing but is rarely built around writing a quote in a driveway. Another is a dedicated invoicing tool aimed at freelancers and consultants, where the workflow assumes a desk, a laptop and clients who pay by bank transfer rather than card on the spot.
Then there is the paper-and-spreadsheet approach, which costs nothing and works until the volume of jobs makes it fragile. The gap Joist occupies is the on-site moment: producing a professional-looking estimate before you leave, attaching photos, capturing a signature, and taking a card payment. A general ledger program will not do that, and a freelancer invoicing app is not designed for a roofer pricing a tear-off.
The trade-off with a specialized tool is that you are relying on someone else's idea of how a contracting business should run. If your process is unusual, a spreadsheet will bend further. If your process is the ordinary one, the structure here is likely to be an improvement on it.
Points to weigh before committing
The main caveat is that the app is cloud-based, so the records live online and are reachable from any device and the web.
The third is focus. This is an estimate and invoice tool for trade contractors, and it is organized around jobs, clients, schedules and payments. That narrowness is the point, but it does mean the app is not a general business management suite, and it does not try to be one.
A worthwhile tool for quoting on site
Joist earns consideration because it solves a specific, recurring problem well: getting a professional estimate into a customer's hands quickly, then turning that estimate into an invoice and a payment without re-entering anything. The calendar, the client records, the photo attachments and the card payments all support that single loop, and the developer has been refining it since 2014.
It suits solo tradespeople and small crews in the listed trades, particularly those who currently lose evenings to paperwork or lose jobs because a competitor quoted first.
If your work is priced per job, performed at a customer's location and billed on completion, this is a sensible app to try. If your billing runs on hourly timesheets or corporate purchase orders, the fit will be looser.
The short verdict
A focused estimate and invoice app that suits trade contractors who quote and bill on site.

What can I actually do with Joist?

Estimates and invoices can be previewed, printed or emailed on the spot.
Does Joist cost anything?
The app is free to download and free to estimate with. There are no ads, and in-app purchases are offered in the form of Joist Pro and Joist Elite subscriptions, each available monthly or annually. Auto-renewal continues unless you switch it off at least 24 hours before the period ends.
Can clients pay me through the app?
Yes. Clients can pay by credit card in the app, so there is no need to chase checks. It also keeps track of customer payments and how much you are still owed, so you can see outstanding balances rather than trying to remember them.
Can I get a client's signature on a contract?
