Plumbing invoices without the paperwork backlog
A burst pipe at 8pm, a boiler service booked in for the morning, and last week's call-outs still sitting unbilled. Log the parts and hours on your phone while you're still on site, and ServiceInvoice turns that job straight into a branded PDF you can send before you're back in the van.
No credit card required to start.
Why plumbers choose ServiceInvoice
Whether you run one van solo or send a couple of mates to different jobs each morning.
Invoice before you’re back in the van
Wrap up the repair, tap through the job on your phone, and the invoice is already built — no pile of write-ups waiting for you at the end of the week.
Call-out fee, fittings, and hours as separate lines
List your call-out charge, every valve, tap, or length of pipe you fitted, and your hours as individual entries, with a higher rate for evenings and emergencies.
Fewer overdue accounts to chase
A due date sits on every invoice, and the dashboard flags what’s outstanding, so a slow-paying customer gets a nudge before the job turns into a write-off.
Bill every kind of plumbing job
An 11pm burst pipe and a booked-in bathroom refit are priced on completely different logic — ServiceInvoice follows whichever structure fits the job instead of forcing both through the same template.
- Emergency and out-of-hours call-outs billed at a clear premium over daytime rates
- Bathroom and kitchen fit-outs quoted as one fixed price once the scope is known
- Boiler services and landlord safety checks billed on a recurring schedule
- Investigative work, like tracing a hidden leak, billed hourly with a materials allowance
Beyond the invoice, ServiceInvoice also keeps a running record of your customers and job history as part of the wider trade business software, and the same call-out-and-parts setup works just as well if you browse it as HVAC invoicing software.
The five lines every plumbing invoice needs
Plumbing jobs get queried more than most, especially when a customer wasn’t expecting the parts bill. Set the invoice up like this and there’s nothing left to argue about once the tap’s fixed.
- Call-out or minimum charge
- Put your call-out or minimum charge on its own line, and mark it up for evenings, weekends, and genuine emergencies, so an 11pm leak isn’t billed at the daytime rate by mistake.
- Parts and fittings
- List each valve, tap, and length of pipe with quantity and price, so a customer flicking through the invoice can match every part to something they watched you fit.
- Labour and hours
- Show your hours and hourly rate, or the fixed price you quoted, on its own line — never folded into the cost of parts.
- VAT, if you’re registered
- Registered plumbers show their VAT number and the VAT amount as a separate line; if you’re not registered, that line simply doesn’t appear.
- Payment terms and how to pay
- State when payment is due — most sole traders give 7 to 14 days — and how you accept it, so there’s no excuse for a customer to sit on it.
Log the call-out, the parts, and your hours, and ServiceInvoice lays each one out as its own line automatically — the invoice is finished before you're back in the van. It's the same system behind our pages for electricians and HVAC engineers.
Pricing mistakes that cost plumbers money
Plumbing quotes get challenged more than most trade invoices, usually because the pricing structure was never made explicit in the first place. A few habits separate a bill customers pay without question from one they call to argue about.
Charging the same call-out fee at 11pm as at 11am
Set a separate emergency or out-of-hours rate — commonly 1.5x to 2x the standard call-out — and mention it on the phone before you drive over, not for the first time on the invoice.
Folding fittings and parts quietly into the labour figure
List every valve, tap, and length of pipe with its own quantity and price. It protects your parts markup and gives the customer something to check the bill against instead of one number to dispute.
Quoting a fixed price before opening the wall
Hidden pipework is the classic trap. Quote fixed only for known-scope jobs, such as fitting a named appliance, and quote hourly plus a materials allowance for anything that starts with "find the leak."
Skipping the minimum charge on a five-minute fix
A washer change still costs you the drive over and the parking. A minimum call-out charge covers the trip regardless of how quick the repair itself turns out to be.
Invoicing weeks after the job because the write-up got buried
The longer the gap between finishing and billing, the hazier the customer’s memory of what was agreed — and the easier it is for payment to stall on a query.
Sample invoice: evening emergency call-out
- Emergency call-out (after 6pm)
- £85.00
- Compression fitting + 1.5m copper pipe
- £22.00
- Labour, 1.25 hrs @ £55/hr (emergency rate)
- £68.75
- VAT (20%)
- £35.15
- Total due
- £210.90
Because the call-out premium, the parts, and the hours each sit on their own line, the customer can see exactly why an after-hours leak costs more than the same repair at 10am — nothing left to dispute once the tap stops dripping.
ServiceInvoice builds each of these lines from the job you log on site, so the emergency premium, the parts, and the hours come out separated automatically — no extra maths on the drive home.
