For carpenters and joiners

Invoicing for carpenters and joiners

An oak staircase for a homeowner, fitted wardrobes, a run of decking, and second fix on a contractor’s site. Quote the work, book each day on the Schedule with the client emailed to say when you’re coming, and invoice from the job when it’s done. When you work for a main contractor, first fix goes in when the joists, the studs, and the door linings are done, second fix when the doors are hung and the architrave is on. Invoice each one on its own, with the labour split from the materials, and Sendinvo takes the CIS deduction off the labour alone, prints the reverse-charge wording where it applies, and chases the main contractor for the net.

30 days of everything, free. No card needed.

Private work and the contractor’s site

Four things a carpenter’s paperwork has to get right

“The staircase quote came back accepted and I nearly forgot to book it in.”

Private work, from the quote to paid

Press Start job on the accepted quote and the client, the site, and the quote come with it. Book each day of the fit on the Schedule, and Sendinvo emails the client to say when you’re coming. Jobs with nothing booked wait under To book, and when the last visit is finished, Raise invoice fills the invoice in from the quote.

How jobs work

“First fix went in months before I could invoice the second.”

First fix and second fix, on their own invoices

Bill the first fix once the linings and the studwork are signed off, then the second fix as its own invoice when the doors, the skirting, and the architrave are on. Each one carries its own labour, materials, and due date. If you’d rather send one invoice for the job, a CIS invoice can carry a payment plan too, each stage paid net of its share of the deduction. Duplicate the first fix invoice and the lines, each still labour or materials, and the reverse-charge tick all come across.

Duplicating an invoice

“The deduction came off my timber as well as my labour.”

Labour split from the materials

Labour on one line, materials on another, marked as materials. The deduction is worked out on the labour alone, so the ironmongery and the architrave you paid for keep their full value. Leave every line as labour and the deduction comes off the whole subtotal, which is right when the week on site was labour only.

How CIS invoices work

“Accounts sent it back over the reverse-charge line.”

The wording the accounts office looks for

If you’re VAT registered, the domestic reverse charge is a tick box sitting next to the applied deduction. Ticked, the VAT line reads “Reverse charge” beside the rate and the invoice prints the wording HMRC expects, with the rate and the VAT figure the main contractor accounts for. Whether it applies to the job is your call.

The VAT reverse charge

Around those four: reminders start when you send and escalate at 1, 7, and 14 days past due unless you change them, so a payment run that keeps slipping is chased without you writing another “just checking” email. If a main contractor goes past the term on a sterling invoice, one press drafts a separate statutory interest invoice for you to read before it goes, and when their accounts office asks what’s outstanding across the plots, a client statement lists every issued invoice and the total still owed on one branded page. On private work, a staircase or a fitted kitchen for a homeowner, ask for a deposit or split the job across stages with a payment plan, then connect Stripe to put a pay link on the invoice, payable by card or straight from the bank, with Stripe’s processing fees applying.

The real app, filled with a carpenter’s fortnight. It opens on the Schedule: fitted wardrobes on site this afternoon, a bookcase and desk finished this morning and ready to invoice, and a Shaker kitchen and second fix on a contractor’s plots booked in. Behind it are a fitted kitchen on a stage plan, a materials deposit on a wardrobe fit, and a staircase quote out with a homeowner. Have a click around.

A worked example

First fix and second fix, invoiced one at a time

Two invoices to the same main contractor on the same loft conversion. It is standard-rated work and both firms are VAT registered, so the reverse charge applies, and the deduction is 20% of the labour lines on each one.

First fix invoice to a main contractor
Labour, first fix carpentry, loft conversion £2,600.00
Materials, timber, noggins, and door linings £900.00
Subtotal £3,500.00
VAT 20% Reverse charge
CIS deduction (20% on labour) −£520.00
Amount due £2,980.00
Second fix invoice, same loft conversion
Labour, second fix carpentry, loft conversion £3,400.00
Materials, ironmongery and architrave £1,150.00
Subtotal £4,550.00
VAT 20% Reverse charge
CIS deduction (20% on labour) −£680.00
Amount due £3,870.00

The deduction is 20% of the labour on each invoice and never touches the materials. The reverse-charge line states the VAT the main contractor accounts for, worked out on the full net: £700.00 on the first fix, £910.00 on the second. When the contractor pays the net, each invoice settles in full.

Questions

Good to know

Can I book the work in as well?

Yes. Press Start job on an accepted quote and book each day on the Schedule, all day or for the morning or the afternoon. Sendinvo emails the client to say when you’re coming, unless you untick the box. When the last visit is finished the job reads Ready to invoice, and Raise invoice fills the invoice in from the quote.

Can I invoice first fix and second fix separately?

Yes. Each fix goes out as its own invoice, with its own labour and materials, its own deduction, and its own due date. If you’d rather send one invoice for the job, a CIS invoice can carry a payment plan too, each stage paid net of its share of the deduction. When the second fix is done, duplicate the first fix invoice and the lines, each still labour or materials, and the reverse-charge tick all come across for you to edit.

Does the CIS deduction come off my materials?

No. Put the labour and the materials on their own lines, mark the materials lines as materials, and the deduction is worked out on the labour alone. The ironmongery, the architrave, and the door linings keep their full value. Every line is labour until you say otherwise, so a labour-only invoice needs nothing marked.

Where does the reverse-charge wording come from?

If you’re VAT registered, the domestic reverse charge is a tick box next to an applied CIS deduction. Ticked, the VAT line reads “Reverse charge” beside the rate and the invoice prints the wording HMRC expects, with the rate and the VAT figure the main contractor accounts for. Whether it applies to the job is your call.

Can my monthly subcontract be a recurring invoice?

A recurring invoice goes out on its own dates and carries your VAT rate, but it can’t carry a CIS deduction or the reverse charge. So a monthly second fix under CIS is raised as a one-off invoice each month, duplicated from the last one. A recurring invoice suits the work that sits outside CIS, like a standing repairs round for a letting agent.

Can I send the sign-off photos with the invoice?

Yes, on the email. Photos of the finished second fix and a signed variation sheet ride along with the invoice email, up to 10 MB across 10 files, not counting the invoice PDF. Nothing is printed on the invoice, so what the accounts office opens is still just an invoice.

Invoice each fix with the deduction already worked out.
