Best invoice app for contractors and tradesmen in 2026
Six estimate and invoice apps for contractors, including two you can start for free
For a contractor, the invoice is where the job finally turns into money, and it usually starts life as an estimate written weeks earlier. So the best invoice app for contractors is really an estimate and invoice app, one that turns the quote into the bill without retyping a line.
The apps below range from simple phone invoicing to full construction management, and only two have a plan that stays free. We read each company's own pricing page in November 2026 and noted the limits that bite: invoice caps, change orders and whether there is a calendar at all.
Workeey is one of the six, and we make it. Where another app does a job better, this page says so plainly.

Checked November 4, 2026 on each company's own pricing or product page, and on app store listings for phone apps (Joist, Invoice Simple and Square figures re-used from our November 3, 2026 check of the same pages). Prices are in US dollars before tax; card fees are set by each provider. This compares published plans and features, not a hands-on test of every product.
Invoice2go
Best fit: a small contracting business that bills occasionally and wants several people in one account.
Invoice2go is built around sending invoices from the phone. Every plan includes unlimited team members, appointments and scheduling, client communications and a business bank account, and bank transfers from clients are free. Professional adds QuickBooks and Xero integration; Premium adds recurring invoices and phone support.
The limit is volume. Starter allows 30 invoices a year on yearly billing and Professional 100 a year, which a busy contractor can pass by spring. Unlimited invoices need Premium. Card fees are set by the plan and drop on the higher plans.
Pricing: Starter $7.99 a month or $79.99 a year, Professional $11.99 a month or $119.99 a year, Premium $44.99 a month or $449.99 a year. A 30-day trial comes first.
Who should look elsewhere: a contractor sending more than a couple of invoices a week who does not want to pay for the top plan.

Joist
Best fit: a renovation or repair contractor whose business runs on estimates.
Joist was designed around the contractor's paperwork. You write the estimate on site, send it, and convert it to an invoice when the work is done. Pro unlocks unlimited documents with your logo, photos and line items, plus work orders. Elite brings change orders and prints your license and insurance on every document, handy when a homeowner asks whether you are licensed and insured.
There is no calendar until the Run plan, so Joist is a paperwork tool first.
Pricing: Basics $10 a month with five documents a month, Pro $17, Elite $32, and Run $70 a month at an introductory price. Joist's free plan is no longer offered; its 14-day trial needs no card.
Who should look elsewhere: anyone hoping for a free plan, or a contractor who wants scheduling without the top tier.

Invoice Simple
Best fit: a side-business contractor who sends a handful of invoices a month.
You build an invoice, estimate or receipt on the phone, send it with an online payment option, and see when the client opens it. Plus adds photos and due-date reminders, useful for showing finished work. Premium adds deposits and premium templates.
Its caps are tight for full-time work: three invoices a month on Essentials and ten on Plus. There is no schedule or job list on its pricing page, so it covers the billing and nothing before it.
Pricing: Essentials $6.99 a month or $69.99 a year, Plus $14.99 a month, Premium $21.99 a month. No permanent free plan, though the company runs a free online invoice generator; a 14-day trial is offered on mobile.
Who should look elsewhere: a contractor who invoices weekly or more.

Square Invoices
Best fit: a contractor who wants unlimited free invoices and already uses Square to take cards.
Square Free lists unlimited invoices and estimates, recurring invoices, deposits and automatic reminders, at $0 a month. Square Plus adds payment schedules, so a deck or kitchen job can be billed in milestones, along with estimates that offer several packages. The same Square account handles in-person card payments.
Its invoices pricing page shows no work calendar or job record, so the planning happens somewhere else.
Pricing: Square Free $0 a month; Square Plus $49 a month per location. Card fees are set by Square on each payment.
Who should look elsewhere: a contractor who wants the estimate, the schedule and the invoice tied to one job.

Contractor Foreman
Best fit: a general contractor or builder who needs job costing, change orders and progress billing as well as invoices.
Contractor Foreman is construction management software, so invoicing is one piece of a much bigger kit. Its pricing page lists estimates with bulk and line-item markups and online approval by the client, invoices with time and material billing and online payments, change orders the client approves on screen, progress invoicing in the AIA style with retainage tracking, time cards, punchlists and QuickBooks Online integration. None of the other apps here lists AIA-style progress billing on its pricing page.
The pricing page shows which plan carries which feature with check marks only, so confirm the features you need before you pick a plan.
Pricing: billed annually, Basic is $49 a month for one user, Standard $105 for up to three, Plus $166 for up to eight, Pro $221 for up to fifteen and Unlimited $332. A 30-day free trial is offered, with a 100-day money-back guarantee on the larger plans. It has iPhone and Android apps.
Who should look elsewhere: a one-person service contractor who only needs to send quotes and invoices.

Workeey
Best fit: a solo contractor who wants estimates, invoices and the week's jobs in one app, starting on a free plan.
Workeey's free plan has no end date and asks for no card. It gives you unlimited invoicing, 23 quick estimates a month and 10 payment reminder texts a month, sent only on the invoices where you switch them on. You price from your own rates and the lines you have saved before. The estimate goes out as a quote PDF from your phone, a deposit percent can print on it, and once the client tells you yes, one tap makes it the invoice.
The invoice is emailed with a pay link, and the client pays by card, Apple Pay, Google Pay or US bank transfer through your own Stripe account, with a small processing fee. If you write the invoice in a basement with no signal it is saved, and you email it once you have signal again. Link your bank and payments that match an invoice mark it paid. The schedule books time slots, repeats a job for the next 12 visits, and orders the day's stops into a route, and an assistant takes typed or spoken requests. Pro adds Google Calendar and QuickBooks sync and 30 texts a month; Premium makes texts unlimited.
It has no change orders or progress billing like Contractor Foreman's, collects no deposits through the app, and has no card reader or tap to pay like Square's. The client cannot accept the quote inside Workeey; they say yes to you. There are no crew or team logins. Workeey is built for the phone: the Android app is on Google Play, it runs in any phone's browser, and a desktop version is coming soon.
Pricing: free; Pro $5 a month; Premium $19 a month.
Who should look elsewhere: a contractor who bills general contractors in stages, needs change orders, or runs a crew.

How to choose an invoice app as a contractor
Count your invoices before you compare prices. Look at last year's busiest month and multiply by twelve. Several of these apps look cheap until you hit a cap of three invoices a month, five documents a month or 30 invoices a year, and then the real price is the top plan.
Decide how much of the job the app should hold. Billing alone needs only a simple invoice app; jobs that change halfway need change orders. If you work for general contractors who ask for pay applications and hold back retainage, you need progress billing, and that narrows the field to construction software.
Check how the client pays. A pay link in the invoice email beats waiting for a mailed check, and on large invoices many clients would rather pay by bank transfer than card.
Get your numbers right before the first quote. The free hourly rate calculator works out what an hour of your time has to cost, and the markup calculator shows what a materials markup really earns you. Then run one real job through your top two picks. For apps by trade, see the best apps for tradespeople.

What is the best free invoice app for contractors?
Two apps here have plans that stay free. Square Free includes unlimited invoices and estimates and suits a contractor who takes cards in person. Workeey's free plan includes unlimited invoicing, 23 estimates a month and a job schedule, with no card needed. The others offer trials, not free plans.
Which app is best for both estimates and invoices?
Joist and Workeey both turn an estimate into the invoice without retyping. Joist adds change orders on its third plan. Workeey makes the switch on its free plan, without change orders. Contractor Foreman goes further with markups and progress billing, at a higher price.
Can a client approve the estimate inside the app?
In some of them. Contractor Foreman lists online approval of estimates and of change orders. In Workeey, the client says yes to you directly; there is no online acceptance or signature.
Do contractor invoice apps take bank payments?
Most do. Invoice2go lists free bank transfers on every plan, and Workeey's pay link takes US bank transfers through your own Stripe account as well as cards, Apple Pay and Google Pay.
