Sometimes the honest answer is no. Here are the five questions that decide it, before you sign up for anything.

Every trade software website is confident you need it. Very few will tell you when you do not, so here is the version nobody sells: work through these five questions honestly and the answer usually falls out on its own.
If you can answer with a figure, your system is working, whatever it is. If the answer is “I’d have to go and look, and I’m not sure I’d find it all”, that is the single strongest argument for changing something — unpaid invoices you cannot see are the most expensive thing on this list.
Not turnover — profit, per job. If you cannot, you are pricing on instinct. That works until it does not, and the point at which it stops working is invisible without per-job figures. More on that in busy but broke.
Same day, most of the time, is healthy. If it is regularly a week because invoicing means a laptop and an evening, you have a cash flow problem caused by a workflow problem, and that is exactly the sort of thing a tool fixes cheaply — see getting paid the day you finish.
If handing your accountant a year’s records means a fortnight of shoeboxes and bank statements, the cost is not just the fortnight — it is the expenses you never found and the relief you never claimed. If it is one export, you are fine.
If you have a crew, a subbie or someone doing your books who needs to see the same information, you need something shared, and that is a genuinely different requirement from a one-person business. If it is only ever you, the coordination features most platforms are built around are not solving a problem you have.
Then do not buy anything. A disciplined spreadsheet, a proper invoice template and a habit of photographing receipts covers a low-volume one-person business perfectly well — the free invoice template is there for exactly that. Adding software you do not need is how people end up paying monthly for something they opened twice.
You do not have to jump to a full platform. If the problem is that admin does not happen on site, the fix is capture where you already are: text the miles, snap the receipt, quote from the van, end the job and send the invoice before you drive off. That is what GraftG does — Solo £14/month, Pro £24/month, Team £34/month, 14-day free trial, nothing to install. If instead the problem is dispatching engineers or wanting your VAT filing in one place, buy the thing built for that; GraftG keeps and exports your records rather than filing them. WhatsApp vs a job management app lays out both sides.
Not always. If you can say who owes you money, which jobs made a profit, and you invoice the same day and hand over one clean export at year end, your current system is doing its job. The case for change is strongest when unpaid invoices or per-job profit are invisible to you.
Start with the habits rather than the spend: invoice the same day, photograph every receipt, log miles as you drive, and chase from the day after the due date. A free invoice template plus those habits beats paid software you do not open.
If you need to dispatch and route several engineers, run complex multi-week projects with stock control, or keep your full accounts ledger and file VAT in one system. GraftG keeps your records and produces accountant-ready exports; your accountant or your own accounting software does the filing.
