Maintenance Contracts — How to Build Recurring Revenue Into Your Trade Business

You know the feeling — January hits, work dries up, and suddenly you're staring at a calendar with three jobs booked across two weeks and the silence is getting loud. Or it's the opposite problem: you're flat out, but every dollar you earn has to be earned again from scratch next week. There's no buffer. No month where the phone can be quiet and you're still turning a profit.

That's the trap of a pure project-based trade business. You're always one quiet month away from stress, and every hour you work is an hour you sell. There's no compound. No residual. No client who pays you whether you show up or not.

Maintenance contracts fix that. Not completely — nothing fixes a slow market completely — but they build a floor under your revenue that changes how your business feels to run.

A maintenance contract is simple: the client agrees to a regular service visit — quarterly, half-yearly, annually — and you invoice them on a schedule. They get priority booking, consistent pricing, and the peace of mind that their equipment or property is being looked after. You get predictable income, better client relationships, and work you can schedule around your big jobs instead of the other way around.

It's not glamorous. Nobody's cutting a ribbon over a filter change. But a dozen $250 quarterly contracts is a thousand dollars a month that lands whether you pick up the phone or not. Stack enough of those and your business starts breathing differently.

Almost any trade can make this work if you look at your work the right way. Here's what it looks like by trade:

Electricians — Annual safety switch (RCD) testing is mandated in Queensland now, and most homeowners don't realise it's their responsibility. Same goes for smoke alarm compliance, switchboard thermal imaging, and periodic safety inspections. These aren't optional extras — they're legal requirements that make perfect recurring service offerings.

Plumbers — Hot water system annual checks, backflow prevention device testing, drain camera inspections on commercial properties. Strata and body corporate love having a plumber on a schedule because it means one less thing for them to chase.

HVAC techs — Filter changes, gas pressure checks, condenser coil cleans. Air conditioners that don't get serviced fail mid-summer when you're busiest. A spring service contract keeps your calendar full in the shoulder season and prevents the emergency call that ruins your day.

Painters — Exterior inspection and touch-up programs for strata buildings, commercial properties, and high-end residential. A yearly walk-around catches issues before they become repaint jobs.

Gardeners and lawn care — This one's obvious. Weekly or fortnightly mowing contracts are the textbook example of recurring trade revenue. The whole business model runs on it.

The common thread is simple: any work that's scheduled, not emergency. Any inspection, test, or preventative task that a client would rather not think about. That's a contract candidate.

The biggest mistake tradies make when starting contracts is under-pricing. They look at the one-hour visit and price it like a call-out, forgetting everything that comes with being on contract: priority access (which means bumping other work when the contract client calls), locked-in pricing (you can't raise rates mid-contract on a whim), and the admin overhead of managing 50 recurring schedules instead of 30 one-off jobs.

Price at 20–30% above what you'd charge for the same visit as a one-off. The client gets priority, predictability, and the convenience of not having to find a tradie every time. That's worth the premium. If they push back, show them what your emergency call-out rate is and watch how fast the contract looks reasonable.

Package them in tiers:

• ✓**Bronze** — Annual inspection only. Basic report. No call-back included.
• ✓**Silver** — Inspection plus one priority callback per year for minor adjustments.
• ✓**Gold** — Everything above, plus a discount on any additional work booked during the visit.

Let the client choose. Most will pick silver, which is exactly where your margin sits best.

Here's where it gets real. A contract model is administratively heavier than project work. You've got recurring schedules that need to fire on time, automated invoicing, reminders for renewal dates, and a history of every visit so you're not guessing what you did last year.

You cannot run this on sticky notes and a whiteboard. The tradie who tries is the tradie who forgets renewals, misses service dates, and ends up with angry clients who paid for a year of coverage and got six months.

TradeTrack handles the scheduling, invoicing, and client history side of maintenance contracts without needing a separate system. Set up the client as a recurring job, pick your interval — monthly, quarterly, half-yearly, annual — and the system prompts you when it's due. Invoice from the job, log the visit notes, attach photos of what you found. Next year when you pull up that client, everything from the previous visit is right there. No filing cabinet. No "I think we did that in March."

The Xero sync means your recurring invoices flow straight into your accounting without double-handling. And because the jobs are scheduled in TradeTrack, you can see at a glance how much contract revenue you've got lined up for the next quarter — which is exactly the information you need to decide whether to take on that big commercial project or let it go.

Best fit: Any trade business with a stable local client base, especially in residential service work. If you've got 200 past clients who you did good work for, there's a contract offering in there for at least a quarter of them. Electricians and HVAC techs in particular have regulatory hooks that make contracts almost mandatory.

Probably not the fit: New businesses without a client history yet. One-man-band operators who are already flat out and don't have the admin capacity to set up a contract system. Builders doing project-based new homes — there's nothing recurring about a new build. But even then, a handover inspection contract at 6 months and 12 months post-completion is worth considering.

Don't overthink it. Pick one service you already do regularly — RCD testing, filter changes, gutter cleaning — and offer it as a contract to your existing clients. Offer the first visit at a small discount to get them in the door. Run three months of contracts, fix the things that annoy you about the process, then expand.

That first contract client who pays you every quarter without a reminder call? That's the feeling you're building towards. It's quiet. It's boring. And it's the most profitable thing you'll add to your business all year.
