For builders & building contractors

Invoicing for builders and building contractors

Extensions, loft conversions, renovations, and groundworks are paid in stages, not in one go at the end. Set the stages once on one invoice, each with its own amount and due date, and Sendinvo chases the stage that’s due while you get on with the build.

Your first 3 invoices are free to send, no card needed.

The shape of a build

From accepted quote to final fix

Quote accepted

The client accepts a priced quote online, then you convert it into a pre-filled invoice you review, stage up, and save.

Deposit on start

Money in before the diggers arrive: the deposit is the first instalment of the payment plan.

Stage payments

Each stage falls due on its own date, payable by bank transfer or by card once you connect Stripe.

Wind and watertight

Halfway money, and anything taken out of the spec put right with a credit note.

Completion

The last stage chased for you, and one click drafts a statutory interest invoice if it runs over.

Built for a long job

Stage money, subcontractors, and the paperwork between

The stages, set once

Split a draft invoice into instalments that add up to the contract total: a deposit as the first instalment, then a payment per sign-off. Sendinvo chases the stage that’s due, then re-points to the next as the money lands. See deposits and payment plans.

Subcontracting, both directions

Work you take on for another contractor goes out as a CIS invoice: turn CIS on in your settings, tick it on the invoice, enter the labour figure, and Sendinvo works out the deduction and the net amount due. If you’re VAT registered, tick the domestic reverse charge alongside it and the HMRC wording lands on the document for you.

Variations, credited to the penny

Specs move on site. When work comes out, a credit note nets off the invoice at the rate it was billed at, so nobody argues over the difference.

Something for the accounts team

Download a client statement and a developer’s finance team gets every issued invoice, its balance, and the total outstanding on one branded page.

A worked example

A £30,000 extension, paid in four

One payment plan on one invoice, four stages tied to the sign-offs on site.

Payment plan for a single-storey extension
Deposit on start £8,000.00 Paid
Slab and footings £6,000.00 Next due
Wind and watertight £10,000.00
Completion £6,000.00
Total £30,000.00

Each stage is chased on its own date, and payable by card once you connect Stripe. As one is paid, chasing moves to the next.

Questions

Good to know

Can I bill a build in stages?

Yes. Split a draft invoice into a payment plan: a deposit as the first instalment, then one for each stage, every one with its own amount and due date, adding up to the contract total. Payment plans are available on a paid plan.

Does Sendinvo handle CIS deductions?

Yes. Turn CIS on in your settings and set your rate, 20%, 30%, or 0% for gross-payment status. Then tick “Apply CIS deduction” on a sterling invoice and enter the labour figure: Sendinvo works out the deduction and shows a net amount due. When the contractor pays the net amount, the invoice settles in full.

Can I put a CIS invoice on a payment plan?

No. A CIS invoice can’t be combined with a deposit or a payment plan. Bill subcontract work as its own CIS invoice, and keep stage payments for the jobs you invoice direct.

What happens when the spec changes mid-build?

Issue a credit note against the invoice for the work that came out. The value nets off the invoice’s balance to the penny, at the rates it was billed at. If that clears the debt, the invoice settles to paid and its reminders stop.

Can a developer’s accounts team see the whole account?

Yes. A client statement lists every issued invoice for that client with its status, total, and outstanding balance, plus the total still owed across them all. It downloads as an A4 PDF in your own branding, ready to send.
