CRM for Plumbers: Win the Estimate, Keep the Customer

Why plumbers need a CRM

A CRM for plumbers records every enquiry, estimate and customer conversation in one place, so work is won on follow-up rather than lost to a busy week. Plumbing businesses live on two kinds of work: urgent call-outs that arrive by phone and message at any hour, and planned jobs such as bathroom refits, boiler swaps and repiping that need an estimate and a follow-up before anyone says yes.

Both leak revenue in the same places:

• Estimates are sent and forgotten. The biggest jobs need a quote, and a quote without a follow-up is often a job for someone else.
• The customer's history is missing. When a landlord calls about a leak, nobody in the office knows what was replaced at that address two years ago.
• Messages arrive everywhere. Photos of a dripping valve on WhatsApp, a refit brief by email, a question on Instagram.
• Repeat work is invisible. Annual boiler services and landlord safety checks are recurring revenue only if someone knows who is due.

Customermates is a focused plumbing CRM for these problems. It is not dispatch software: it does not schedule engineers, plan routes or send invoices. It keeps the commercial side of your business in order next to the tools you already use for that.

How a plumbing business runs on Customermates

One pipeline for call-outs and planned jobs

Deals are your jobs, and the stage is a field you configure. Many plumbing businesses use two views of the same pipeline:

• Call-outs: Logged → Attended → Completed → Paid
• Planned work: Enquiry → Survey → Estimate sent → Accepted → Booked → Completed

The kanban board shows each job as a card; grouping by owner shows each engineer's jobs, and grouping by a job type field separates emergencies from refits. Stage probabilities turn open estimates into a weighted pipeline value, calculated from your own weights.

Property and customer history

Organizations and contacts hold landlords, letting agents, property managers and homeowners. Link each job to the customer and, for landlords and agents, to the right organization, so the history of every property is one click away. See contact management.

Fields for plumbing work

Custom columns let you record what matters to your trade: job type (emergency, repair, installation, refit, service), property type, boiler make and model, last service date, next service due, access notes, and a link to the photo folder in your file storage. Records do not store file attachments, so keep the photos where they are and store the link.

Following up on estimates

A saved view of jobs in Estimate sent, sorted by last update, is your daily follow-up list. On Customermates Cloud, a routine can prepare it for you: each morning the Mate assistant lists estimates older than five days and drafts a short follow-up message for each, which you review before anything is sent. Starter includes 1 routine per user and Pro includes 5.

Annual services and landlord checks

Put a Next service due date on the customer or the job, and a saved view sorted by that date shows who to contact next. That turns annual boiler services and landlord safety checks into planned work instead of a memory exercise.

WhatsApp, email and Instagram in one inbox

On Pro and above, the unified inbox brings WhatsApp, email, Instagram, LinkedIn and Telegram into the CRM. Link a conversation to the customer once and every later message shows up on their record; reply from the office on the channel the customer used. Phone calls and SMS are not channels.

AI for the paperwork

External AI clients such as Claude or ChatGPT connect through MCP and can create jobs from a description, add survey notes to the right record, or summarize a customer's history before a visit. Customermates registers 49 MCP tools, and you choose and pay for the AI client. On Customermates Cloud, the built-in Mate assistant does the same work inside the app.

Plumbing CRM or field service software?

Field service platforms are priced for the whole operation: on 27 September 2026, Jobber listed its Core plan from $49 per month billed monthly, Housecall Pro its Basic plan from $79 per month billed monthly, and ServiceTitan did not publish prices. Customermates starts at €12 per user per month and can also be self-hosted.

Pricing for plumbing businesses

• Starter (€12 per user per month): jobs, customers, properties, custom fields, views, REST, webhooks and MCP.
• Pro (€29 per user per month): adds the unified inbox for WhatsApp, email, Instagram, LinkedIn and Telegram.
• Self-hosted: run the open-source core on your own server with Docker; the inbox and Mate are cloud-only.

A three-person plumbing business pays €36 per month on Starter. See pricing.
