A plumber might do one job a day. A handyman does five: a fence panel in the morning, two flat-pack builds, a leaking tap washer, then hanging a mirror on the way home. Each one is a customer, a price, an invoice and a payment to chase. The work is easy. The paperwork multiplied by five is what breaks people, and it is why searches for a handyman invoicing app in the UK keep climbing.
The maths nobody talks about
Say a typical small job is worth £60 and the admin around it takes ten minutes: writing the invoice, sending it, recording it, checking later whether it was paid. Ten minutes on a £60 job is an admin overhead most consultants would call catastrophic, and you are doing it five times a day. That is nearly an hour of unpaid work daily, usually done on the sofa when you are done in. Over a working year it adds up to weeks of your life spent typing names and addresses into invoices worth less than a tank of diesel each.
The volume is the problem, so the fix has to attack time per invoice, not just tidiness. An invoicing system that takes four minutes instead of ten is not a nice-to-have at your job count. It is two and a half hours a week back.
Pricing odd jobs on the doorstep
Handyman pricing has a unique pressure: the customer is standing next to you, waiting for a number, for a job you have not fully seen yet. A few rules keep you out of trouble:
- Have a minimum call-out in your head and never go below it. The tap washer is ten minutes, but getting there, parking and being available was not.
- Price the second job on the spot. The while-you-are-here request is where handyman work makes money, because the travel is already paid for. Quote it immediately and confidently.
- Say the price out loud and follow it with a message. A one-line text confirming the figure prevents ninety percent of doorstep disputes later. It also means the price exists somewhere other than two people's memories.
Thirty open invoices and no idea which are paid
Here is the failure mode that actually costs handymen money. It is not the customer who refuses to pay. It is the twelve quid here and forty quid there that nobody chased because you genuinely could not remember whether Mrs Patel on Elm Road had transferred it. With thirty small invoices in flight at any one time, your bank statement becomes a puzzle: a £45 credit with the reference RENT is somebody paying for the shelf job, probably, maybe.
You need one list, in one place, that answers a single question: who still owes me money? Not a spreadsheet you update fortnightly. A running list that gets a tick the moment a payment lands. Most handymen who lose money to unpaid invoices do not lose it to bad customers. They lose it to their own bookkeeping lag. If your whole admin routine needs a rethink, our guide to running sole trader admin in one hour a week is built around exactly this problem.
What a handyman invoicing app actually needs
Judged against the five-jobs-a-day reality, most invoicing apps fail on the same three counts. They assume you invoice from a desk, so the interface wants a keyboard and patience. They assume low volume, so creating an invoice is a ceremony with templates and previews. And they live in yet another app, which means one more login you will not open at 7pm in the van.
The right tool for this trade sends an invoice in the time it takes to text a mate, works one-handed in the cab, and keeps the paid-or-not list current without you maintaining it.
Where GraftG comes in
That is precisely the gap GraftG is being built to fill, and it is coming soon. GraftG turns WhatsApp into your back office: you message one number with the job details and the invoice goes out; the payment list updates as you confirm what has landed; receipts get photographed and logged in the same chat; mileage and a job tracker ride along too. There is no app to download and no dashboard, because the whole point is that you already have WhatsApp open. For a handyman, that means the tap washer job is invoiced before you have pulled off the kerb, not at 9pm.
GraftG launches soon. If five invoices a day is stealing your evenings, join the waitlist now at graftg.co.uk. Your admin sorted. Just WhatsApp it.
