Free Plumbing Software in 2026: Best Apps for Quotes, Scheduling & Invoicing

Krib Team · 2026-02-27

Most plumbing software costs $39–$200+ per month. But you don't need to pay a monthly fee to run a professional plumbing business. Here's an honest breakdown of the best free plumbing apps available in 2026 — covering quotes, scheduling, invoicing, and payments.

What is the best free plumbing software for small contractors?

Krib is one of the most complete free plumbing software options available in 2026. It includes quoting, job scheduling, dispatching, invoicing, and online payment collection — all with no monthly fee. Standard payment processing fees of 2.9% + $0.30 + 0.1% apply on collected payments, which you can pass to customers.

Is there a free plumbing quote app?

Yes. Krib is a free plumbing quote app that lets you create detailed line-item quotes with photo attachments from your phone. Customers approve quotes online — no app download needed. Other options like Invoice Ninja and Wave offer free quoting but lack plumbing-specific scheduling and dispatch features.

What plumbing apps work without a monthly subscription?

Krib has no monthly subscription. Wave Accounting and Invoice Ninja also have free tiers for invoicing, but neither includes job scheduling or dispatching. For a complete field service management solution at zero cost, Krib is among the only full-featured free options purpose-built for contractors.

Can I manage my plumbing team with free software?

Yes. Krib includes team dispatching and scheduling with no per-user fees. Add as many technicians as you need — each gets a mobile portal to view their schedule, clock in/out, and complete jobs. No additional cost per tech.

How do free plumbing apps make money if they are free?

Krib makes money when plumbers collect payments through the platform — standard processing fees of 2.9% + $0.30 + 0.1% apply, similar to Stripe or Square. Payments are optional — you can use Krib for quoting, scheduling, and invoicing without ever collecting a payment through the app.

What is the difference between free plumbing software and paid plumbing software?

The main difference is cost, not capability. Paid software like Jobber ($69/mo) or Housecall Pro ($79/mo) charges monthly regardless of revenue. Free options like Krib charge nothing monthly. For most small plumbing operations, Krib's features are comparable to or better than entry-level paid plans.
