Invoicing software for UK trades
Send UK-compliant invoices the moment a job is finished, track who's paid and who hasn't, and stop chasing payments at the kitchen table on a Sunday.
Built for the way UK service businesses actually work
- Send a full invoice from your phone — straight after the job, while you're still on site.
- UK-compliant by default — sequential invoice numbers, VAT lines if you're registered, payment terms.
- One-tap payment links for your customer — most users get paid days or weeks faster.
- See exactly who owes what — outstanding invoices, overdue invoices, paid invoices, in one view.
- Quote → job → invoice in one flow — no rekeying, no copy-paste between apps.
Who it's for
WrkGenie's invoicing is used by electricians, plumbers, cleaners, gardeners, and handyman businesses across the UK — from sole traders to small teams.
If you also need to quote work or manage jobs in the same tool, WrkGenie ties all three together — no separate apps, no double-entry.
How UK trades use this feature
Cleaning businesses
Cleaning companies invoice differently depending on the client — cash domestic customers pay per visit, agencies expect same-day invoices after changeovers, and commercial contracts often bill monthly in arrears. Late invoices mean late payment, especially from facilities managers who close their books on fixed dates.
WrkGenie lets you invoice immediately after each clean while still on site, or batch monthly for contract clients without rebuilding line items from scratch. Each property sits under one client account with its own rate and history, so an agency querying a line on a multi-site invoice is easy to answer.
Payment links on every invoice mean domestic customers tap to pay by card — no chasing bank details over text. Recurring invoice templates handle monthly commercial contracts so you are not manually recreating the same document on the first of every month.
Electricians
Electricians often finish a job, pack up the van, and intend to invoice that evening — then forget until the customer chases a week later. By then the details are fuzzy and the payment delay has already started.
WrkGenie invoicing is built for on-site completion: the job record already has the customer, the agreed price from the quote, and any variations logged on site. One tap sends a UK-compliant invoice with sequential numbering, VAT if you are registered, and a payment link the customer can use immediately.
For larger installs, raise a deposit invoice when the quote is accepted and the final balance on sign-off — all against the same job record. Landlord and commercial clients get itemised breakdowns; domestic customers get a clean single-line invoice if that is what they prefer.
Plumbers
Plumbing invoices go wrong in predictable ways — materials cost more than quoted, the emergency callout runs longer than expected, or the landlord wants a separate invoice per property on a multi-site job. Without a system, each scenario means rebuilding the invoice from memory.
WrkGenie connects the invoice to the job: parts used on site, hours logged, and any agreed variation are already on the record. Send the invoice before you leave the property on callout work, or raise a deposit and final invoice on a boiler install without re-entering customer details.
VAT-registered plumbers get automatic VAT lines; non-registered businesses send clean net invoices. Overdue tracking shows which landlords and agents still owe from last month — so you chase from one screen instead of scrolling through sent emails.

Practical invoicing details UK service businesses care about
VAT invoices
If you're VAT registered, invoices include your VAT number, a separate VAT line, and the correct tax totals automatically. If you're not yet registered, invoices are sent without VAT fields — you update your settings when the threshold changes and all future invoices update accordingly. The current UK VAT threshold is £90,000 turnover.
Late payment charges
UK law allows businesses to charge statutory interest on overdue invoices under the Late Payment of Commercial Debts Act. WrkGenie's invoice overdue tracking makes it straightforward to see which invoices have passed their terms — whether you choose to charge late fees or simply follow up with a reminder.
Deposit invoices
For larger jobs — building work, boiler installs, full rewires — it's standard practice to invoice a deposit before work starts and the balance on completion. WrkGenie lets you raise multiple invoices against the same job record, so the quote, deposit invoice, and final invoice all sit in one place.
Recurring invoices for regular customers
If you have maintenance contracts, monthly retainers, or regular service agreements, recurring invoice templates save time and reduce the chance of forgetting to bill. Set the amount and the interval, and the invoice is created ready to send each period.
Sequential invoice numbering
UK invoices must have a unique sequential reference number. WrkGenie handles this automatically — no gaps, no duplicates, and no manually keeping track of what number you're up to.

Common questions about WrkGenie invoicing
Can I create invoices from my phone?
Yes. WrkGenie is mobile-first — you can raise and send a full UK-compliant invoice from your phone the moment a job is finished, while you're still on site. No laptop required, no paperwork to fill in later.
Can I add VAT to invoices automatically?
Yes. If you're VAT-registered, enable VAT in your settings and WrkGenie will add your VAT number, the correct VAT rate, and the VAT amount to every invoice automatically. The current UK VAT registration threshold is £90,000 turnover. If you're not yet registered, invoices are sent without VAT fields — you update your settings when the threshold changes.
Can customers pay invoices online?
Yes. Every invoice includes a payment link. Customers can pay by card directly from the invoice — no bank transfer guesswork, no 'I'll get you the sort code' conversations. Most WrkGenie users report getting paid days or weeks faster after switching to payment-linked invoices.
Can I convert a quote into an invoice?
Yes. Once a quoted job is complete, you convert it to an invoice in one tap — all the line items, the customer details, and the agreed price carry over automatically. No rekeying, no separate apps, no copy-pasting between spreadsheets.
Does WrkGenie support recurring invoices?
Yes. For maintenance contracts, monthly retainers, and regular service agreements, you can set up recurring invoice templates. Set the amount and the interval and the invoice is generated ready to send each period — useful for landlords, cleaning contracts, and annual service visits.
