Best Plumber Service Agreement Software: 6 Picks for 2027

The category decision: buy agreements inside your field platform

Plumber service agreement software is a field-service or billing tool that stores each recurring maintenance contract, schedules its visits, renews or bills the plan, and shows the owner how many agreements are active.

Our read is that most small plumbing shops should use the agreement module inside a field platform they already run for dispatch and invoicing, rather than add a standalone contract tool. A renewal depends on the same customer record, equipment list and visit history that the scheduler already holds, so a separate tool means keeping a second copy of that data in sync. A standalone tool makes more sense when a shop is committed to a scheduler it does not want to replace.

The demand is real, which is why the choice matters. Housecall Pro's own 2025 survey found 51% of homeowners expect a membership plan or service agreement from a home service provider, according to Housecall Pro (2025). Because that survey was run by a software vendor, treat it as vendor-run data. A survey run by myCLEARopinion for ACHR News, published February 4, 2025, shows the homeowner side: Homeowner interest: 57% would spend about $100 a year according to ACHR News (2025). The question asked what homeowners would want if they had an agreement, so that figure measures interest, not a vendor price.

TL;DR: Housecall Pro and Service Fusion publish list prices. Housecall Pro keeps recurring service plans on its Max tier. ServiceTitan's help pages cover the most agreement mechanics of the six we read, but it is quote-based. FieldPulse and Workiz need a demo to confirm packaging. FieldEdge lists service agreements in all three of its tiers.

Key Takeaways

• Only Housecall Pro and Service Fusion show plan prices on the pricing pages we opened. The other four use request-pricing buttons, so this guide labels them Quote-based.

• On Housecall Pro, recurring service plans appear on the Max tier, not on Basic or Essentials.

• ServiceTitan treats residential memberships and commercial service agreements as different products, and they renew differently.

• FieldPulse ties renewal reminders to an end date, limits agreement access for some staff roles, and offers no customer self-service for agreements.

• A Zapier, Make or n8n build can reach the same outcome, but you own the audit trail, retries, escalation and access rules.

• Workiz's pricing page ties service plans to its Ultimate tier, while its feature page names no tier, so get the packaging in writing before you sign.

How we evaluated these tools

This guide covers six products that each describe a membership or service-agreement feature on a page we opened, all aimed at home service contractors. We left out Jobber because its pricing page showed no membership or service-agreement feature, and ServiceM8 because its pricing page lists recurring jobs without an agreement feature. The weights below are our judgment about what a plumbing owner needs to decide. Facts come from the pages cited inline, and statements marked "Our read" are our analysis.

We weighted renewal and billing as high as model fit because a missed renewal or an unbilled visit costs the shop directly. Reporting is weighted lower because fewer of the vendor pages we opened describe it in detail. We did not score review-site ratings. The review-site pages we tried to open returned access errors, so no rating appears in this guide.

Published prices and the quote-based gap

Pricing checked November 13, 2026. Only figures printed on a vendor's own pricing page appear in this section. Third-party guides publish conflicting numbers for the same tools, so we left them out.

Housecall Pro's Max plan costs $299 to $329 a month according to Housecall Pro (2026). The page shows both figures without labels, so we read the lower one as the annual-billing rate, which matches how its Basic and Essentials cards are laid out. Max also includes recurring service plans and eight users, with $35 a month for each additional user.

Service Fusion's Starter plan costs $245 a month, or $208 a month billed annually, according to Service Fusion (2026). Its page says plans are month-to-month and that annual billing carries a 15% discount. The table below uses only the figures cited in this section.

The 12-month column multiplies the annual-billing rate by 12. It excludes tax, add-ons and extra users, so it is a floor for budgeting, not a total cost of ownership.

The other four vendors do not publish plan prices on the pages we opened. ServiceTitan's pricing page says, "Our per-technician pricing is designed to fit your business and goals, at any size," and each tier shows a request-pricing button. FieldEdge's pricing page says "Pricing is not published." FieldPulse's pricing page describes seat-based pricing and a custom quote. Workiz's pricing page shows a request-pricing button on each of its three tiers.

Some third-party guides publish ranges for these four tools. We do not repeat them, because none came from a vendor's own pricing page, and this guide prints only those figures.

What each tool records for a plumbing agreement

The matrix below sets out what each vendor's own pages say about the agreement record. "Not described" means the page we opened did not say, which is not the same as saying the feature is missing.

ServiceTitan's help center draws the line between its two products this way: memberships are for residential work and service agreements for commercial work, according to ServiceTitan. Its help article says ongoing memberships do not expire, while service agreements can be set to auto-renew or end on a set date.

FieldPulse's help center sets the most explicit limits of the six. Each agreement uses one plan type, and renewal reminders appear only when an end date is set, according to FieldPulse. Customers cannot self-serve, and recurring billing setup is available only on the web.

Our read: renewal handling and reporting are described on fewer vendor pages than scheduling and billing. That gap is where a buyer should spend the most demo time.

Six vendor profiles

Each profile separates what the vendor's page says from our read.

Housecall Pro

Best fit: owner-operators who already schedule and invoice in Housecall Pro and want recurring service plans. Vendor page: Housecall Pro's pricing page places Recurring Service Plans on Max, which includes eight users with $35 a month for each additional user. Limitations: Our read is that a shop with a larger team pays extra per seat on top of the Max rate, so price it for the team you will have. Implementation: confirm the Max tier, the user count and who may edit plan templates before enrolling customers. Evidence: Housecall Pro's recurring service agreements page.

ServiceTitan

Best fit: larger shops that sell residential memberships and commercial service agreements, and expect a quote before they buy. Vendor page: the help center separates memberships from service agreements, offers billing schedules for both, and includes a Time of Service option for agreements. Its maintenance agreements page says contractors can produce a contract performance summary showing completed visits and value, and that the software connects to QuickBooks Online and QuickBooks Desktop. Limitations: that marketing page is aimed at HVAC, so ask for plumbing examples in the demo. Our read: two products mean two sets of plan rules to configure and train staff on. Implementation: decide which customers get a membership and which get an agreement before data entry starts. Pricing: quote-based.

FieldEdge

Best fit: shops that want agreements included at a lower tier and a clear upgrade path. Vendor page: FieldEdge's pricing page lists Select, Premier and Elite. Select includes basic agreements and quotes, Premier adds advanced service agreements, and Elite includes all Premier features. Limitations: pricing is not published, and the page does not describe renewal or billing behavior, so ask for a demo of both. Implementation: request a written tier comparison that names the agreement features in each tier before you sign. Our read: when agreement depth depends on the tier, the upgrade decision is also a cost decision.

Service Fusion

Best fit: shops that want published monthly prices, month-to-month terms and simple scheduled billing for agreements. Vendor page: the pricing page lists Starter, Plus and Pro at the prices in the table above. Limitations: its service agreements post describes most agreement features as still being built, and it does not describe a dedicated renewal or reporting feature. Implementation: run a few agreements through a full renewal cycle and a reporting check during a trial before moving the whole customer book. Our read: the published prices make this the easiest tool to budget for, but renewals and reporting are the first things to test.

FieldPulse

Best fit: shops that want two agreement types, scheduled visits and on-demand visit allowances, with agreements tied to jobs and recurring billing. Vendor page: its maintenance agreements help article says scheduled agreements create dated occurrences, while on-demand agreements give a set number of visits per period that staff claim when a customer calls. Limitations: limited agents cannot access agreements, customers cannot self-serve, and renewal reminders need an end date. Pricing: FieldPulse's pricing page describes seat-based pricing and a custom quote. Implementation: set agent permissions and end dates before launch, because reminders depend on the end date. Our read: an agreement with no end date suits indefinite service, but it gets no renewal reminder.

Workiz

Best fit: shops already on Workiz that want reusable service-plan templates and automatic reminders. Vendor page: its service plans page says templates define service intervals, visit counts, pricing and billing frequency, and that enrolled clients get visits and invoices generated automatically, with reminders before each visit. Clients can see their plans and payment history in the client portal. Limitations: the pricing page lists service plans only on Ultimate, while the feature page names no tier and does not say whether plans are an add-on. Ask Workiz to confirm packaging in writing. Implementation: build the templates first, because visit intervals, visit counts, pricing and billing frequency are set there.

Renewals and failed payments: a workflow you can configure

Renewal outreach and failed-payment follow-up are where a maintenance plan either holds or leaks. Agreement adoption: about 20% to 25% of homeowners according to Contracting Business (2026). That figure comes from the founder of SmartAC, quoted in the article, and it describes HVAC maintenance agreements generally. Treat it as self-reported context, not a plumbing benchmark.

The first proposed workflow is renewal outreach. This is a configurable design, not a live deployment. The trigger is an agreement record that reaches a set number of days before its end date, read from a scheduled export of agreement records out of your field platform. The action pulls the customer, equipment list and visit count from that export and drafts a renewal note in Gmail. The output is the draft plus a task in a queue, such as a Google Sheet or a HubSpot record. The review point is an office person who approves, edits or rejects each draft, so nothing reaches a customer without that approval. Prerequisites are an export that includes the end date and visit history, a Gmail account with permission to send, and a named owner for the queue. A US Tech Automations build would configure these steps and fix the review points before launch.

The second proposed workflow handles failed payments. Where agreements bill through Stripe, the trigger is the invoice.payment_failed event, which Stripe documents as sent when a payment for an invoice fails, according to Stripe. Stripe's documentation also says a failed renewal moves a subscription to past_due, which the workflow can use as a second trigger. The action creates a follow-up task with the customer, the agreement and the amount, and drafts a customer notice. The output is a task in the office queue plus that draft. The review point is that the office decides whether to retry, call or pause, and the workflow never cancels an agreement. Prerequisites are a connected Stripe account, a webhook endpoint that verifies Stripe's signatures, and a rule for shops whose field platform uses its own payment processor, where the trigger must come from that platform's export instead.

Here is an illustrative case, not a customer: a shop with 60 annual agreements at $200 each bills $12,000 a year. If 5 of those renewals fail in one cycle, that is 5 ÷ 60 = 8.3% of agreements and $1,000 in billing at risk. If each failure fires invoice.payment_failed and creates a same-day task, the office can call the customer within a day. If the failures surface only in a monthly report, the $1,000 can sit for weeks while the agreements keep getting scheduled.

Build it yourself in Zapier, Make or n8n?

Zapier, Make and n8n can cover the same two workflows. When configured, those tools can keep run histories, retry failed steps and route errors to a separate branch. The owner still has to design what a template does not decide: idempotency, so a retried step does not send a customer two notices; escalation when a task sits unopened; access controls for who can see customer and payment data; and maintenance when the field platform changes its export format. A US Tech Automations design would name those same points as review gates and list prerequisites before the build, so the owner signs off on them rather than finding them later. A self-built flow stays in the owner's hands for good, which suits a shop with someone who will maintain it. A managed build is a service decision, and the owner should weigh who will keep the flow running.

Who should choose what

Who this is for

This guide is for an owner or operations lead at a small home services business who sells or wants to sell recurring maintenance and is close to choosing a platform.

Red flags: you have no agreements sold yet; you cannot export agreement records from your current system; you expect renewals to go out with no one reviewing them.

When NOT to use US Tech Automations

Three scenarios where a simpler tool wins. If you only need a printable agreement and a calendar reminder, the agreement template in your current field platform is simpler. If your platform already sends renewal reminders and bills the plan, a workflow layer adds a second system to reconcile. If you cannot export agreement records at all, the first step is the platform or export change, and there is nothing to automate yet.

Glossary

• Service agreement: a recurring maintenance contract that schedules visits and defines what is covered.

• Membership: ServiceTitan's term for a prebuilt residential plan; ongoing memberships do not expire.

• Auto-renew: a setting that renews an agreement when its term ends.

• Time of Service billing: invoicing that creates a bill only after a visit is performed, offered by ServiceTitan for agreements.

• Recurring job: a job the platform creates again on a set schedule.

• Webhook: a message one system sends another when an event happens, such as a failed payment.

• Review point: a named step where a person approves an action before it leaves the business.

Decision checklist before you sign

• Ask the vendor to name, in writing, the tier that includes agreements.
• Export a sample of current agreements and confirm the platform can import the fields you need.
• Confirm whether renewal reminders go to customers and who approves them.
• Ask for a report of active, expiring and renewed agreements, and watch it run during the demo.
• Confirm which payment processor bills the plans and how failed payments appear.
• Get per-user and add-on costs in writing from every quote-based vendor.
• Name the person who clears the renewal queue each week.

Questions buyers ask

Which plumber service agreement software is best overall?

No single tool wins for every shop; for published prices and scheduled billing, Service Fusion is the clearest starting point, while ServiceTitan's help pages cover the most agreement mechanics but require a quote.

Does Housecall Pro include recurring service plans on every plan?

No. The pricing page lists Recurring Service Plans on the Max tier, not on Basic or Essentials.

Can customers manage their own agreements in FieldPulse?

No. The FieldPulse help center says customer portal self-service for maintenance agreements is not available.

Why does this guide leave prices out for four vendors?

ServiceTitan, FieldEdge, FieldPulse and Workiz show only request-pricing buttons on the pages we opened, so we label them Quote-based rather than estimate them.

Is the 51% membership figure neutral?

No. It comes from Housecall Pro's own 2025 survey, so treat it as vendor-run data.

Can I build this in Zapier, Make or n8n instead?

Yes, for the two workflows above, but you own the design of retries, escalation, audit evidence and access control, and you still need an export from your field platform.

Does US Tech Automations replace a field platform?

No. The proposed workflows sit beside a field platform, need its exports, and leave scheduling, dispatch and billing where they are.

Bottom line

Start with the billing and renewal model you already run, then make each vendor show it in a demo before you compare prices. Housecall Pro and Service Fusion give you published numbers to test against; the other four need a quote before you can compare. If you want a configured layer for renewal outreach and failed-payment follow-up, see how US Tech Automations configures this for the prerequisites and review points.
