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

Decker Pro is plumbing contractor software priced at $39/month flat for up to ten team members. The features that traditionally made contractor software expensive — dispatch boards, multi-site management, technician utilisation, custom checklists for compliance work, full audit trails — are all in the Pro tier. The features that made it bloated (CRM probability scoring, marketing automation pipelines, partner referral portals) aren't here at all.

What you get for $39/month flat on the Pro tier as a plumbing contractor team:

• Sites & locations — multi-site customers (property managers, housing associations, schools) get organised by site, not just by address.
• Machines & equipment inventory — every boiler, every cylinder, every pump tracked individually with its service history, parts log and photos.
• Plumbers management — assign by skill (gas-safe registered, unvented system, commercial plumbing), by proximity (closest van), by current load.
• Custom checklists — gas safety records, unvented commissioning, water hygiene checks — each as a template, filled on-site, signed digitally, attached to the customer.
• Stock requests & shipments — your plumber on a job needs three 22mm elbows and a flux brush. They flag it, your office sees it, parts arrive at the next job.
• Activity log & audit trail — who serviced what boiler, when, with whose Gas Safe registration. Insurance-ready paper trail without any extra effort.
• Lead pipeline — track potential customers from initial enquiry through quoted, won, and onboarded. No more lost-in-WhatsApp leads.

For a 5-plumber contractor team, a comparable Jobber Connect setup runs roughly $200–$400/month once additional users (+$29/user) and payment processing fees are factored in (based on Jobber's public pricing page). ServiceTitan typically starts at $400+ with a multi-year commitment attached. Decker Pro is $39/month, flat, locked for life as a founding customer. The same plumbing contractor software, without the contractor-priced price tag.

Plumbing quoting software and plumbing estimating software are the same thing 90% of the time — the customer needs a number before they agree to the work, and you need that number to convert into the invoice when the work's done. Most "best plumbing software" lists separate these into two paid modules. Decker doesn't.

Build a plumbing estimate in 90 seconds: labour hours × your hourly rate, parts at cost × your markup percentage, callout fee, VAT/GST/sales tax applied for your region. Save as a template (e.g. "Standard combi-boiler swap"). Send by WhatsApp with a one-tap accept button. When the customer accepts, the estimate becomes the job. When the job's done, the estimate becomes the invoice. One workflow.

When people search for "best plumbing software" or "best software for plumbers," they're usually weighing three things: price (does it bankrupt a one-plumber operation?), mobile usability (does it actually work in a customer's airing cupboard?), and depth (does it handle plumbing-specific things like gas-safe, Worcester boilers, VAT on labour vs parts?). Decker is built to win all three. Try the free plumbing invoice generator below — it uses the exact same engine that's inside the paid Decker app, so you can see the quality before you commit.

Invoice software for plumbers, on the truck. Most plumbing invoice software lives on a desktop. Decker is invoicing software for plumbers designed phone-first — build the invoice on the customer's driveway, send by WhatsApp, get paid before you pack up. The same plumbing invoice software, but priced for actual plumbers at $19/mo flat.

Plumbing invoice software vs invoicing software for plumbers — same thing. Both terms describe what Decker does: line-item builder, regional tax (VAT, GST, sales tax), parts markup, callout fee, photos attached, Stripe pay link. The plumbing invoice software included in Decker is the same engine inside the free plumbing invoice template on our tools page — try it before you commit.

Plumbing job management software — the full operational loop. Plumbing job management software is the term for software that runs the entire job lifecycle: lead → quote → scheduled → on-the-way WhatsApp → on-site → completed → invoiced → paid → history archived. Decker handles the whole loop in one workflow. No status forgotten. No "did I bill that?" moments on Sunday night.

Plumber software for the actual day, not for the office. Most "plumber software" was designed for office dispatchers. Decker is built for the plumber holding a phone with one hand while the other hand is in the airing cupboard. Quote, schedule, invoice, take payment — all one-handed, all in under 60 seconds per action.
