Decker
Plumber software · Solo $19/mo

Plumber software built by someone who's been in the field.

Emergency callouts, parts you forgot to invoice for, customers who pay 30 days late — the actual problems of solo plumbing, solved by software that doesn't pretend you're a 20-truck dispatcher. $19/month flat. Locked for life.

Expected launch: 30–45 days from your pre-order. 90-day refund guarantee — if Decker isn't live in your hands by Day 90, full refund, no questions.

Built for the plumber's day

The four problems generic software ignores.

If you've ever tried to make a generic CRM behave like plumber software, you'll recognize all four.

Emergency callouts

Burst pipe at 2pm. Add the job in 15 seconds, re-route your day, ping the next customer "I'm running 90 minutes late" via WhatsApp. No drama.

Parts you forgot to invoice

Add a line item from the van as you fit it. Photo of the part, price, done. No more "did I bill them for the trap?" on Sunday night.

Customers who pay late

Automatic WhatsApp nudges at 3 and 7 days. Polite, professional. Most invoices get paid before you'd have noticed they were late.

Repeat work for the same customer

Every job, photo, part, invoice — pinned against the customer. Walk back in 18 months later already knowing what you replaced.

Plumber features

Six tools for the actual plumbing day.

Quotes & estimates

Send a quote in 60 seconds — line items, photos, price. Customer accepts on WhatsApp. Approved quote converts to invoice when the job's done.

Mobile invoicing in 60 seconds

Build and send the invoice from the customer's driveway. Parts, labour, photos, tax handling, Stripe pay link — one screen.

One-tap WhatsApp invoicing & messaging

Generate the booking confirmation, the "I'm 15 minutes away" ping or the payment nudge — tap once, send it from your own WhatsApp. Customers actually read it.

Photo job notes with annotations

Before-and-after photos against the job. Annotate the leak, mark the part. Proof for the customer, proof for you.

Recurring jobs & service contracts

Annual boiler service, quarterly check-ins — set once, Decker auto-generates the jobs and pings the customer.

Customer CRM & full history

Every call, job, photo, invoice and quote against the customer. Walk back in eighteen months knowing exactly what you replaced.

Founding pricing

$19/month. Flat. Locked for life.

Plumber software, finally priced for actual plumbers.

As a solo plumber, you've probably tried two or three pieces of plumbing business software by now. Maybe Jobber, maybe Housecall Pro, maybe a generic CRM bolted to a spreadsheet. The complaint is always the same: the best apps for plumbers were never actually designed for one-person plumbing operations. They were designed for plumbing contractor software buyers — multi-truck shops with a dispatcher, an admin, a sales team. You're paying for all that complexity even though it's just you in the van.

Decker is plumber scheduling software, plumbing invoice software, plumbing service software and a CRM for plumbers — all in one flat $19/month subscription. Not "starting at." Not "from." Flat. The price you see today is the price you'll pay forever as a founding customer, because we built Decker for solo plumbers and small plumbing teams from day one, and we don't believe in upsell-driven pricing.

For plumbing businesses that have outgrown solo, Decker Pro at $39/month adds sites, machines, technicians, custom checklists, stock requests, shipments and a leaderboard — the right stack for a two- to ten-truck plumbing contractor. The software for plumbers you'll grow into without re-platforming, and without your bill ever exceeding $39/month. (Compare that to what a comparable plumbing dispatch software setup costs on Jobber or Housecall Pro — typically $200–$300/month at the same team size, before per-message and per-user fees.)

What makes Decker the best app for plumbers specifically: emergency callouts work like emergency callouts (add a job in 15 seconds, auto-notify everyone affected on WhatsApp), invoices include the parts you fitted (line-item from the van, photo of the part, no Sunday-night reconciliation), and the customer history sits behind every job (walk back in 18 months knowing exactly what you replaced). Plumbing company software shouldn't make you feel like you work for the software. Decker is built so the opposite is true.

If you're a solo plumber, a husband-and-wife plumbing operation, or a small plumbing contractor team — reserve a founding spot at $19/mo (or $39/mo for Pro). Lock the price for life. Stop paying for plumbing software designed for someone else's business.

Plumber FAQ

Five questions plumbers always ask.

What's the best plumber software for solo operators?

Decker. It's the only plumber software priced flat at $19/month (founding rate, locked for life) with all the features a solo plumber actually uses — scheduling, mobile invoicing, customer CRM, WhatsApp reminders and Stripe payments. No add-ons, no per-user fees.

Can I handle emergency callouts in Decker?

Yes. Add an emergency job in 15 seconds. Decker re-routes your day, notifies affected customers via WhatsApp, and flags emergency-rate line items on the invoice.

Does Decker support parts ordering and stock?

Solo includes a simple parts list per job. Pro adds full stock requests and shipments between sites — useful once you're running a two- or three-truck plumbing operation.

Can I take card payments on the spot?

Yes. Stripe is built in. Tap to pay, Apple Pay, Google Pay, card — all from a WhatsApp invoice link. Money in your account next day.

Will Decker remind me to chase unpaid invoices?

Decker chases them for you. Automatic, polite WhatsApp nudges at 3 days and 7 days. Most invoices get paid before you'd have noticed they were late.
