The electrician who switched 47 clients in a fortnight
Last month, I got a message from an electrician in Manchester. He'd moved 47 of his regular clients from card payments to bank-to-bank invoicing in just fourteen days. On a typical month of £8,000 in invoices, he was now saving £340. That's not loose change for a one-man operation.
The maths nobody talks about
When you're running a trades business solo, every percentage point matters. Credit card processors take 2.5% off the top. On a £500 invoice for a rewire or a weekend job, that's £12.50 gone before you even see the money. Most tradespeople don't do the maths until they've lost a few thousand to fees over the year.
The electrician had been using a card processor for five years. He knew the sting was there. He just didn't know how to fix it without asking his clients to do something difficult. Then he tried Invoicr. The bank-to-bank payment method through UK open banking meant his clients could pay him the same way they pay their energy bills. No new app. No card details. Just their bank, his account, and a straightforward transfer.
On that £500 invoice, the cost dropped to about £4. He ran the numbers. If he could get his regular clients switched over, he'd clear an extra £300 to £400 a month. For a sole trader, that's a second job's worth of margin.
Why the switch happened so fast
I asked him how he managed to move 47 clients in two weeks. His answer was honest: he didn't make it complicated. He sent each regular customer a message. Not a sales pitch. Just, 'I'm now using a faster payment method. Pay me here instead.' He included a link to their client portal. They clicked it, saw their invoice, and hit pay. Most didn't ask questions.
The ones who did ask got a straight answer. No bank details on an email. No asking them to remember account numbers. They logged into their own banking app and sent the money, like they would to any other business. Faster than waiting for a cheque. Easier than hunting for their wallet.
What struck me was that none of them left. Nobody said, 'This is too weird. I'm going back to card.' They just switched. He told me the payment confirmation arrived in his bank the same day, every time. No waiting three to five business days for a card processor to move funds around.
The bigger picture for tradespeople
This electrician isn't unique. We've built Invoicr specifically for people like him. Plumbers, builders, tilers, gardeners, mobile mechanics. People who invoice from a van or a job site. People whose time is their money and who can't afford to throw 2.5% at processing fees.
The Free tier gives you 5 invoices and 3 customers to start. Enough to test whether bank-to-bank payments work with your clients. Most trades people move to Pro once they see the fee difference. That's unlimited invoices, payment reminders (which chase money without you chasing it), and the ability to send invoices via WhatsApp. No fumbling with email addresses. A link goes to their phone, they pay, done.
The platform runs natively on iOS. You invoice on the job. Your client gets the link before you've packed up your tools. The payment lands in your account before you've driven to the next site.
What nobody tells you about payment processors
Card processors make their margin by taking a percentage. The bigger your invoices, the more they take. They have a structural reason to slow down payments to you, because holding money between your client's bank and yours is where they earn float interest.
Bank-to-bank is different. There's a small flat fee because the infrastructure costs something to run. But it's not designed to bleed you over time. The money moves the same day. Your client's bank knows their account is legitimate. Your bank knows it's a real transfer. There's no middleman holding a percentage.
The electrician in Manchester switched because the maths worked. He kept the clients because the friction disappeared. That's the difference between a feature that looks good on paper and one that actually changes how a business works.
The one thing he didn't expect
When I asked what surprised him most, he said it was the reminders. Once he moved to Pro, automated payment reminders started going out. Not angry emails. Just a polite message when an invoice was due. Some clients paid before the reminder even arrived because they saw the notification in their phone and thought, 'Right, I should sort that.' One told him it was actually easier than him having to chase.
He went from spending Tuesday mornings sending payment reminder emails to watching invoices get paid on time automatically. Not through some complicated set of rules, but because clients could see what they owed and when, and they paid it the way they'd pay anyone else.
That's when he realised the fee saving was just the start. The real shift was having his invoicing work for him instead of spending time managing it.
If you're still using a card processor and you've never done the maths on what it costs you each month, maybe it's time to work it out. What if one small change could save you hundreds a year and make your clients' lives simpler at the same time?
