For electricians

Invoicing for electricians

A landlord EICR on Monday, a consumer unit on Wednesday, an EV charger on Friday, and first fix for a main contractor in between. Book each visit and the client is emailed to say when you’re coming. Put the certificate number on the invoice and attach the EICR to the email, and when you work for a main contractor, tick CIS so the deduction comes off the labour before anyone queries it.

30 days of everything, free. No card needed.

Board to bank

From the quote to the money

1

Quote it, then book it

A rewire, a board change, or a day of fault-finding, priced line by line and accepted online with no login for the client. Turn follow-ups on and an unanswered quote nudges itself while you’re on the next job. Once it’s accepted, press Start job and book the visit on the Schedule, and the client is emailed to say when you’re coming. See how quotes work.

2

Get the kit money in first

A charge point and its cable are paid for before you turn a screw, so ask for a materials deposit with its own due date, printed next to the balance. On a full rewire, split the total into stages instead: deposit to book it in, first fix, then the balance on completion and testing. See deposits and payment plans.

3

Send the invoice with the certificate

The certificate number goes on its own line, or in the notes, and prints on the A4 PDF with your logo. The EICR itself rides the same email as an attachment, so the landlord gets the report and the bill in one message instead of chasing you for the paperwork a week later.

4

Get paid, by card or net of CIS

On a domestic job, connect Stripe and the homeowner pays by card from the link before you’ve packed the van. Subcontracting to a main contractor? Switch CIS on, tick it on the invoice, and mark the materials lines. The deduction comes off the labour alone on a CIS invoice, never the cable and back boxes.

The rest of the round

Portfolio testing, slow main contractors, and the reverse charge

Most electricians bill three kinds of client in a week, and each one wants a different invoice: a homeowner who pays on the day, a letting agent on a testing round, and a main contractor who pays when it suits them.

Portfolio EICRs as a recurring invoice

An agent with a managed portfolio wants the same inspection invoice on the same date every month. Set a recurring invoice and each run raises it and emails it without you opening the app. Your standing files go with it, so the public liability certificate the agent asks for is attached to every one.

Subcontract work, netted down before it goes

On CIS work you mark the materials lines and the deduction comes off the labour alone, so the cable and the board you paid for keep their full value. If your company is VAT-registered, a domestic reverse charge tick box appears alongside CIS. Tick it and the invoice carries no VAT and the wording HMRC expects, and the main contractor pays the net amount.

A rewire over several days

Each visit is one day, so a three-day rewire is three visits on one job. The job reads Booked, then In progress, then Ready to invoice as you start and finish them, and Raise invoice fills the invoice in from the quote. Photos of the old board and the new one go on the job, sorted into before, during, and after, as a record for you rather than something printed on the invoice. With an apprentice or a second electrician, each visit is assigned to someone and the client’s email names who’s coming, with your whole team included in the one price.

Sockets that came out of the job

When the layout moves on site and you fit fewer sockets than you quoted, issue a credit note against the invoice. It nets off the balance at the rate the line was billed at, so nobody argues over the difference.

Chased, then charged

A main contractor’s 60 days is your overdraft. Reminders go out at 1, 7, and 14 days past due unless you change them, and they stop the moment the money lands. If a sterling invoice to another business runs over, Sendinvo works out the statutory interest from the Bank of England base rate the law fixes for the debt, plus the fixed compensation the Act allows, £40 on a debt under £1,000. One click drafts a separate invoice for you to read before it goes.

See it in action

An electrical business, seeded and running

The real app, filled with an electrician’s fortnight. It opens on the Schedule: a full rewire on site this afternoon, garden lights finished this morning and ready to invoice, and an EV charger and a letting agent’s EICRs booked in. Behind it are a monthly EICR round for a letting agent, a rewire billed in three stages, a materials deposit for an EV charger, and a landlord EICR gone overdue and being chased.

A worked example

First fix for a main contractor, CIS at 20%

Labour and materials on their own lines, the deduction off the labour alone, and the reverse charge ticked because the work is standard-rated and both sides are VAT-registered.

Invoice to a VAT-registered main contractor
Labour, first fix wiring to shop units 4 and 5 £2,400.00
Cable, back boxes, and first-fix materials £1,150.00
Subtotal £3,550.00
VAT 20% Reverse charge
Total £3,550.00
CIS deduction (20% of the labour) −£480.00 Labour only
Amount due £3,070.00

The deduction is 20% of the £2,400.00 labour, not of the £3,550.00 total, so the cable and back boxes keep their full value. Under the reverse charge the invoice shows no VAT and carries the wording HMRC expects, with the £710.00 the contractor accounts for at their end. Pay the £3,070.00 net and the invoice settles in full.

Questions

Good to know

Can I book the visits as well?

Yes. Press Start job on an accepted quote, then book each visit on the Schedule for the morning, the afternoon, all day, or a set time. Sendinvo emails the client to say when you’re coming, unless you untick the box. A rewire over three days is three visits on one job, and when the last one is finished, Raise invoice fills the invoice in from the job.

Can I put the certificate number on the invoice?

Yes. Put it on its own line next to the inspection, or in the invoice notes, and it prints on the A4 PDF with your logo. Type the same description on the next EICR and Sendinvo offers it back from your own history, price included.

Can I send the EICR itself with the invoice?

Yes, as an attachment on the invoice email, next to the invoice PDF. It doesn’t go on the invoice document itself. One email carries 10 MB across up to 10 files, not counting the invoice PDF, which is room for a full report and a few photos of the board.

Does Sendinvo work out CIS on subcontract work?

Yes. Set your rate once: 20% for a registered subcontractor, 30% if you’re not registered, or 0% for gross-payment status. On a sterling invoice, tick “Apply CIS deduction” and mark the materials lines, and the deduction comes off the labour alone while your cable, board, and fittings keep their full value. The invoice shows the gross total and the net amount the main contractor pays.

Can I bill a letting agent’s portfolio EICRs as a recurring invoice?

Yes. Set a recurring invoice for the portfolio and Sendinvo raises the next one on your date, weekly, monthly, quarterly, or annually, and emails it without you opening the app. When your reminders are on, every invoice it sends is enrolled in them, so an agent who forgets is chased like anyone else.

Can I ask for a materials deposit on an EV charger?

Yes. Ask for a deposit as a percentage or a fixed amount, with its own due date, printed on the invoice next to the balance. On a full rewire, split the total into stages instead, each with its own amount and date, adding up to the job total. An invoice takes one or the other, and a CIS invoice can take either, each payment net of its share of the deduction.
