Job management software for tradesmen: a UK guide

Job management software is the place where every job lives from the first phone call to the money landing in the bank. For a sole trader with a diary in the van, a notebook and a stack of invoices in a carrier bag, it replaces all three. For a firm with five engineers, it’s how the office knows who is where and what’s been done.

You probably need it when one of these starts happening: quotes go out and nobody follows them up, you turn up to a job without the right part, a customer rings to ask where the engineer is and you don’t know, or you find an unpaid invoice from three months ago in the glovebox.

You probably don’t need it yet if you do two or three jobs a week, invoice the same day and remember everything. A paper diary and your accounting app may be enough.

The heart of good job software is a clear set of stages, ideally shown as a board with columns so you can see the whole business at a glance. For most trades they look something like this:

1. Enquiry: who called, what they want, where, how they found you.
2. Site visit: booked, done, with photos and measurements.
3. Quote sent: the amount, the date, and a reminder to chase it after a few days.
4. Booked: the date, the engineer, the materials to order.
5. In progress: for longer jobs, with notes and photos day by day.
6. Complete: signed off by the customer, certificates issued.
7. Invoiced and paid: with overdue invoices in red.
8. Lost or cancelled: so you learn why quotes don’t convert.

A builder will add stage payments and snagging; a heating engineer will add annual service reminders; an electrician will add the certificates that must be issued. The point is that the stages are yours, not a generic “open/closed”.

Quotes win or lose work, and speed matters: the customer who gets your quote the same evening is more likely to say yes than the one who waits a week. Good software lets you build a quote from a price list of labour and materials, add a markup, show VAT correctly if you’re registered, and turn an accepted quote into a job and later an invoice without typing anything twice.

The most valuable feature is often the dullest: a list of quotes waiting for an answer, oldest first. A polite follow-up call after five days converts more work than any marketing.

Scheduling for trades isn’t like a salon diary. Jobs last from an hour to six weeks, travel time matters and the weather moves everything. Look for a diary per engineer or per van, a week view that fits on a phone, and the ability to drag a job to another day when the roofer can’t work in the rain.

If you have a team, the office should see everyone’s day, while each engineer sees only their own jobs, with the address, a tap-to-call number and a map link.

• take photos before, during and after, attached to the job;
• write notes and record materials used;
• log hours, for your own costing and for paying subcontractors;
• get the customer to sign off the work;
• see the job history at that address: what was fitted, when, by whom.

Ask every vendor how their app behaves with no signal. Many tradespeople work in basements, plant rooms and rural areas. Some apps work offline and sync later; many, including browser-based ones, need a connection.

Trades in the UK live with paperwork that has dates attached: gas safety records, electrical installation certificates and EICRs, boiler service reminders, warranties, building control notifications, and your own insurance and accreditation renewals. Missing one costs money, or worse.

The simplest approach is a deadlines list with the due date, the customer or job, and a reminder some weeks before. Many firms also use it to win repeat work: an email to every landlord whose gas safety record is due next month is a week’s work booked without advertising.

Note that issuing official certificates often has to go through your scheme provider’s own system (Gas Safe, NICEIC, NAPIT and others). Job software tracks that the certificate exists and when it’s due; it usually doesn’t replace the official form.

Late payment is the biggest problem for small trade businesses. Your software should show, on its first page, who owes you money and for how long, and link every invoice to the job it came from so that a disputed invoice comes with photos and a signature attached.

Most job apps connect to Xero, QuickBooks or FreeAgent so your accountant gets clean data. Check this before you choose: entering the same invoice in two places is exactly the double work you’re trying to escape. CIS deductions for subcontractors and payroll are best left to your accounting or payroll software.

For most trades, start with the specialists. Fergus, Tradify, Powered Now, ServiceM8, Jobber and Commusoft are all used in the UK, typically from around £25 to £50 a month per user. They come with years of feedback from other tradespeople, integrations with suppliers and accounting packages, and support teams.

Building your own makes sense when your work doesn’t fit their mould: a landscaping firm with seasonal maintenance contracts, a shopfitter with multi-week projects and twenty subcontractors, a firm that does both installations and hire. It also makes sense when per-user pricing for a team of ten becomes a serious line in your accounts.

With Plannify you can describe your firm (“sites, stage payments, labourers’ hours and subcontractors’ insurance certificates”) and a team of AI agents builds the software around it, in front of you, for free with the AI you choose. You get a board for jobs, a diary per engineer, records with photos and notes, a deadlines list and a first page showing what’s due today and who owes you money. You change it by writing in the chat.
