The Problem

Your Agreements Live on Paper and Renew Only When Someone Remembers

It shows up every spring and fall. Tune-ups need scheduling, cards on file have expired, and techs who could sell a plan at the door have no easy way to sign anyone up.

  1. Paper forms

    Techs have no way to sign up a customer on site.

    Paper forms

    A tablet form captures plan choice, e-signature, and card before the tech leaves.

  2. Expired cards

    Renewals fail quietly when cards on file expire.

    Expired cards

    Declined payments retry, and members get a link to update their card.

  3. Late visits

    Spring visits start late while the office builds call lists.

    Late visits

    Each member's seasonal visits are created in your field software ahead of time.

  4. Offline only

    Homeowners can read about your plan but can't buy it.

    Offline only

    Plan tiers on your website take card or ACH sign-ups at any hour.

It's March, and your office manager is sorting a spreadsheet of members to book spring tune-ups. Half the cards on file expired, so renewals fail without anyone noticing. Yesterday your best tech finished a furnace repair, and the homeowner asked about your maintenance plan. The tech had no form, so the sale became a sticky note. Your website mentions a comfort club, but nobody can join it online. Every lapsed member is lost recurring revenue and a future replacement job.

We start with your plan tiers: what each includes, the price, and how visits get scheduled. Then customers join on your website or on a tech's tablet, sign the terms, and pay by card or ACH on your Stripe account. Renewals bill on autopay with retries and reminders, and each member's tune-ups appear in your field software. Agreements renew because the system bills them, not because someone remembered.

  • Plans sold on your website

    Homeowners compare tiers and join online with a card or bank account, any time of day.

  • Sold at the door

    Techs offer the plan on a tablet, capture the signature and card, and the member is active.

  • Renewals on autopay

    Renewals bill on schedule, with retries for declined cards and a notice before each charge.

Our HVAC Service Agreement Software Process

From Plan Review to Members Signing Up in Five Steps

You approve the plan tiers, the agreement terms your attorney signed off, and the sync with your field software, then test a full sign-up and renewal before launch.

  1. We look at your current plans, prices, member count, field software, and how renewals get billed today. You get a short list of what to automate first, our honest view of your software's built-in features, and a fixed-price proposal.

Projects We've Built

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built websites, apps, and platforms for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why HVAC Contractors Trust Us With Recurring Revenue

HVAC Service Agreement Software handles your most predictable income. These habits shape every build, from the first plan review to the first renewal run.

  • Built around your field software

    We work with ServiceTitan Memberships, Housecall Pro Service Plans, or Jobber recurring jobs instead of replacing them. Dispatch stays where your team already works.

  • Terms from your attorney

    Your agreement's legal terms come from your attorney, not from us. We turn the approved text into a signed form and store each signed copy.

  • Renewals tested before launch

    We run renewals, declined cards, and cancellations on test data before members join. A billing bug in March costs you a season of trust.

  • Made for techs in the field

    The tablet form uses big buttons and few fields, so a tech can sign up a member in the driveway. If it takes longer than the invoice, we shorten it.

  • Honest about built-in features

    If your field software's plan feature already covers your offer, we'll tell you before we quote. Many shops need only the online checkout, not a whole platform.

  • Your Stripe, your members

    Payments settle in your own Stripe account, and member data stays in your systems. If you switch field software later, your agreements come with you.

Good fit

  • Shops tracking agreements in spreadsheets

    Your members live in a spreadsheet, and spring tune-ups start late because someone builds the call list by hand.

  • ServiceTitan or Housecall Pro users

    You already use ServiceTitan Memberships or Housecall Pro Service Plans, but customers still can't join or renew from your website.

  • Jobber shops wanting real memberships

    Your team runs maintenance as recurring jobs in Jobber, and a declined card means a manual chase because autopay tries only once.

  • Contractors adding commercial accounts

    Your crew now services rooftop units across several buildings, and the residential plan template can't price per unit or track filters by site.

  • Agencies serving home service brands

    You build websites for HVAC companies and need a partner to add agreement checkout, billing, and field software sync under your brand.

Not a fit

  • Renewal reminders only

    Your agreements bill fine, but lapsed members don't get a call. Our CRM for HVAC and Plumbing Companies service handles renewal follow-up and equipment records.

  • Online booking only

    You want customers to book repair calls online, not buy plans. Our ServiceTitan Integration or Housecall Pro Integration services cover web booking.

  • Legal terms drafted

    You need the legal wording of your agreement written. Your attorney drafts that, and we turn the approved terms into an e-signed form.

  • Budget under $950

    Your shop has a handful of members and a budget under $950. Your field software's built-in plan feature is the better starting point.

FAQ

Frequently Asked Questions

Straight answers on agreement software cost, launch timing, what plans cover, commercial agreements, and selling more plans.

  • Our HVAC service agreement software starts at $950 for an online plans page with checkout, e-signed terms, and autopay renewals. Tech tablet sales, a member portal, and declined-card recovery start at $2,600, and commercial agreements with per-unit pricing start at $5,800. Stripe's processing fees and your field software subscription stay billed to you directly.

  • An online checkout takes 2 to 4 weeks, and a commercial agreement platform takes 8 to 12 weeks. Syncing with your field software and testing renewals take the most time. Launching a few weeks before the spring or fall tune-up season gives techs time to practice the tablet form.

  • A standard HVAC service agreement usually includes one or two tune-ups a year, priority scheduling, and a discount on repairs. Many add waived after-hours fees or a filter plan. The exact mix is your offer, so we set up each tier's visits, discounts, and billing to match whatever you sell.

  • Coverage in an HVAC agreement is whatever your terms say, typically inspection, cleaning, and adjustment during each visit. Parts, refrigerant, and repairs are usually billed separately at a member discount unless a higher tier includes them. We show each tier's coverage on the plans page, so homeowners know what they're buying before they pay.

  • Yes, for most contractors, because commercial agreements bring steady visits and first call on replacements. They need different tools: per-unit pricing, equipment lists by site, preventive maintenance checklists, and invoice billing. An HVAC preventive maintenance agreement for a building full of rooftop units won't fit a residential template, which is what our commercial plan handles.

  • Manage them in one system that bills, schedules, and tracks each agreement, not in a spreadsheet beside your field software. ServiceTitan Memberships creates recurring service events and billing, and Housecall Pro Service Plans handle visits and online renewals. We add online sign-up, field sales, and declined-card recovery around them, or build it standalone.

  • Sell them when the customer trusts you most: at the end of a repair or tune-up. Give techs a tablet form with the tiers, e-signature, and card capture, so the sale closes before they leave the driveway. Clear, priced HVAC maintenance service contracts beat a brochure left on the counter.

  • Sell them online as well as on site. Put a plans page on your website with clear tiers, prices, and a join button that takes card or ACH. Link it from booking confirmations, invoices, and seasonal emails. An HVAC service and maintenance agreement sold online needs the same e-signed terms as one sold on site, so both flows share one agreement template.

  • Start with customers you already serve: every repair invoice and booking confirmation can offer the plan. Past customers without a plan are the next list, reached by email with a link to join online. Each maintenance agreement HVAC customers sign also puts your company first in line when their system needs replacing.

  • You do. Payments settle in your own Stripe account, members stay in your field software, and the code for the checkout and portal is yours. If you move from Jobber to ServiceTitan later, we can move the sync instead of starting over, because billing sits in your Stripe account, not the vendor's.
