An extension or a loft conversion is booked in day by day and paid in stages against the sign-offs on site, not in one go at the end. Start the job from the accepted quote and book each day on site, with the client emailed to say when you’re coming. 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. Work for a main contractor goes out as its own invoice, with the CIS deduction taken off the labour and the reverse-charge wording on it when it applies.
30 days of everything, free. No card needed.
The client accepts a priced quote on their phone. Press Start job and the site and the quote come into a job, with each day on site booked as a visit on the Schedule. Raise invoice opens a draft with the quote’s lines and prices already in it, ready for you to stage up.
Money in before the diggers arrive: the deposit is the first stage of the payment plan, with its own due date.
Slab, wall plate, then wind and watertight: each stage falls due on its own date and the client settles that stage alone, by card once you connect Stripe or by bank transfer.
Work that comes out of the spec goes back to the client as a credit note, netted off at the rate it was billed at.
The last stage chased for you, and if a main contractor runs over on a sterling invoice, one click drafts a separate statutory interest invoice for you to read.
While the invoice is still a draft, split it into the stages the job actually runs to: deposit on start, slab and foundations, wall plate, wind and watertight, completion. Each stage takes its own amount and its own due date, and they have to add up to the invoice total. Once you send it the stages are fixed. Sendinvo chases the stage that’s due, then re-points to the next as the money lands. See deposits and payment plans.
Each visit is one day, so a week of groundworks is five visits on one job. The job reads Booked, In progress, then Ready to invoice as the visits are started and finished, and shows what’s been quoted, invoiced, paid, and left to invoice. Photos of the footings before they’re covered go on the job, sorted into before, during, and after, as a record for you and your team rather than something printed on the invoice. On a team, each visit is assigned to someone, the client’s email names who’s coming, and a Field person sees only their own visits and jobs, with no prices, in the Sendinvo app for iPhone, which is on its way to the App Store. Your whole team is included in the one price.
Work you take on for a main contractor goes out as a CIS invoice. Set your rate once, 20%, 30%, or 0% for gross payment status, then tick the deduction and mark the materials lines: it comes off the labour alone, your materials keep their full value, and the invoice shows the net amount the contractor actually pays. If you are both VAT registered and the work is standard- or reduced-rated, tick the domestic reverse charge alongside it and the wording HMRC expects prints on the document. It doesn’t apply to zero-rated work, such as building a new home, or when the client has told you in writing that they’re an end user.
Specs move on site. When the client drops the bifold for a French door, or supplies the kitchen units themselves, a credit note nets that value off the invoice at the rate it was billed at, so nobody argues over the difference at completion.
Building control completion, the electrician’s certificate, the structural warranty: attach them to the invoice email, up to 10 MB of files, not counting the invoice PDF. They ride alongside the invoice rather than printing on it, so the document the accounts team files stays a clean invoice. See email attachments.
A developer’s finance team wants the whole account, not one invoice at a time. Download a client statement and they get every issued invoice for that client, its status, total, and outstanding balance, plus the total still owed, on one A4 page in your own branding.
The real app, filled with a builder’s work. It opens on the Schedule: a rear extension on site today, another extension and a renovation booked in, and a back door frame waiting under To book. Behind it are a rear extension and a loft conversion on stage plans, a garage conversion booked in with a deposit, a credit note for client-supplied kitchen units, and a maintenance retainer with a developer. Have a click around.
A live demo seeded with a building business. Nothing you do here is saved or sent.
One is a stage plan on your own job. The other is subcontract work for a main contractor, with the CIS deduction already worked out.
Each stage is chased on its own date, and the client settles that stage alone rather than the whole invoice. Above £10,000 a stage goes on the card, because Stripe caps instant bank payment there.
The other one: a shell package for a main contractor on someone else’s site, where the deduction comes off you.
The deduction is 20% of the £6,400.00 labour, never the materials. Both firms are VAT registered, so the invoice charges no VAT and carries the wording HMRC expects, and the main contractor accounts for the £1,830.00 VAT at their end.
Yes. Press Start job on an accepted quote and book each day on site as a visit on the Schedule. Sendinvo emails the client to say when you’re coming, unless you untick the box, and on a team each visit is assigned to someone and the email names who’s coming. Each visit is one day, so a week of groundworks is five visits on one job.
Yes. While the invoice is still a draft, split it into a payment plan: the deposit as the first stage, then a stage per sign-off, each with its own amount and due date, adding up to the invoice total. Once you send it the stages are fixed, and Sendinvo chases the stage that’s due rather than the whole job.
Yes. Set your rate once in company settings, 20%, 30%, or 0% for gross payment status, then tick “Apply CIS deduction” on a sterling invoice and mark the materials lines. The deduction comes off the labour alone, your materials keep their full value, and the invoice shows the gross total and the net amount due. When the main contractor pays that net amount, the invoice settles in full.
No. Sendinvo works on the invoices you send, so CIS here is the deduction a main contractor takes off you. It doesn’t work out what you deduct from the subcontractors you pay, verify them with HMRC, or file a CIS300. That side stays with your accountant.
Yes. A CIS invoice can carry a deposit or a payment plan. Each payment carries its share of the deduction, so the invoice shows what the main contractor pays at each stage, and Sendinvo chases that figure.
Issue a credit note against the invoice for the work that came out. Its value nets off the balance to the penny, at the rate that work was billed at. If that clears what’s left, the invoice settles to paid and its reminders stop. Work that goes in instead is a new invoice.
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 to their finance team.
Reminders keep chasing that stage on the dates you set, and the tone steps up as it runs on. On an overdue sterling invoice to another business, Sendinvo shows the statutory interest accrued and the fixed compensation the Late Payment of Commercial Debts (Interest) Act 1998 allows, from £40 on a debt under £1,000, and one click drafts a separate interest invoice for you to read before it goes. The invoice the contractor already has is left exactly as it went out. This is general information, not legal advice.
30 days of everything, free. No card needed. After that it’s £20 a month, with your whole team included.
