Maintenance contracts in the trades: predictable revenue instead of order gaps
Sold once, revenue every year: maintenance contracts smooth your order book, retain customers and fill the slow months. How to build them — from pricing to the reminder.

A maintenance contract is the agreement to inspect and service equipment regularly for a fixed fee — and the most effective remedy against the seasonal rhythm of full order books and gaps. It turns one-time customers into recurring revenue. Yet few small businesses offer maintenance contracts systematically; those who do gain an advantage that pays off every year.
01Why are maintenance contracts worth it in the trades?
Because they create plannable revenue that doesn't depend on weather or the economy: a base of maintenance contracts is background income — workload for the low season and the shortest path to the follow-up job, because whoever maintains the system also gets the repair and the upgrade. And a business with a contract base is ultimately worth more.
02What belongs in a maintenance contract — and what doesn't?
In: a clearly defined package — inspection and function check, wear-part check, priority in emergencies, travel included. Just as important is the boundary: spare parts and repairs are billed by effort, not in the flat fee. Calculate honestly — labour, travel and admin — and set an annual or monthly price you can sustain.
03When is the best moment to sell a maintenance contract?
Right after the job: offer the contract when the system has just been installed or repaired — as an optional item in the quote or in the wrap-up conversation. The arguments are on the customer's side: preserving value, safety, and many manufacturers tie warranty promises to regular maintenance. One sentence is enough: 'Shall we take care of that automatically from now on?'
04How do you document maintained equipment properly?
With an equipment file per property: whoever maintains needs to know what's installed — manufacturer, model, year, serial number — and what was done on previous visits. Keep that file in your system instead of searching the e-mail archive. In DasHandwerk.xhub you attach equipment to the customer file and have the history at hand on the next visit.
05How do you keep maintenance appointments reliably on track?
With recurring series instead of a card box: the real service in the contract is the reminder — your business gets in touch, not the customer. Set maintenance dates as a recurring series in the calendar, with e-mail reminders so nothing slips. The contract base then almost runs itself, and every appointment produces an invoice instead of a forgotten promise.
The short version
Put together a clear maintenance package at an honest price, offer it right after every job, keep an equipment file per property and set the dates as a recurring series with reminders. Your contract base will then carry you through the off-season — year after year.
