General contractor invoicing software

Invoicing built for running several projects at once

Three supplier accounts to reconcile, two subcontractors waiting to be paid, and a client asking when the next draw is due — ServiceInvoice keeps each project's billing moving on its own timeline instead of piling up into one end-of-month scramble.

No credit card required to start.

Why contractors use ServiceInvoice

Built for owner-operators and small crews running several sites at once, who need billing that keeps pace with the build rather than trailing behind it.

A clear line for every supplier and sub

Timber and fixings from the merchant, your own labour, and invoices from the electrician or plasterer you brought in each show up as a separate line, so a client can see where every dollar of the project went.

One invoice or a schedule of draws

Raise a single invoice when a small job wraps up, or set up a run of draw invoices tied to milestones on a bigger build — either way, the numbering and totals stay consistent from start to finish.

Track outstanding balances across every project

Tax is worked out for you on each invoice, every one is numbered automatically, and a single dashboard lists which projects still have money owed, so a stalled payment on one job does not get lost among the others.

Bill every kind of project

A weekend remodel gets billed differently to a six-month build, and ServiceInvoice lets you set up either one without wrestling a template into shape.

  • A single fixed-price invoice for a defined scope of work
  • A draw schedule tied to milestones on longer builds
  • Supplier materials, your labour, and each sub broken out separately
  • Standing invoicing set up for repeat developer and property clients

Billing is only one piece of running a job site — ServiceInvoice also holds onto every client relationship and project record you build up. Read more about the business software as a whole, or see how it applies to carpenters and joiners.

What belongs on a general contractor invoice

On a construction project, an invoice has to do more than total up a number — it has to hold up if a client, an accountant, or a lender ever asks for the breakdown behind it. Here is what a solid contractor invoice includes.

Which project and which stage
State the project name and, if you are billing against a schedule of draws, exactly which milestone this invoice covers, so the client can check it against the contract in seconds.
Materials supplied
Break out materials by quantity and unit price, with any markup folded in, so the cost of supplies is easy to check independently of your labour charge.
Your labour
Keep hours and rate, or the labour share of a fixed quote, on its own line instead of blending it into the materials total.
Subcontracted trades
List each subcontractor you brought onto the job — electrical, plumbing, plastering, whatever applies — so the client can see the full scope of work you managed for them.
Tax and terms
Break tax out as its own line and state a due date and payment method. On multi-month builds, unambiguous terms at each draw are what keeps money moving while the work continues.

Log a project once in ServiceInvoice and each of these lines fills itself in from the job record, ready to send the moment a milestone closes out. See the carpenters page and the roofing businesses page for how the same lines look in those trades.

Frequently asked questions

Can I bill fixed-price projects and progress draws?
Yes. Send a single fixed-price invoice for a job, or bill in stages as the project progresses. Materials, labour, and subcontractor costs itemised clearly on each.
Can I separate materials, labour, and subcontractors?
Each material, your labour, and any subcontracted work get their own line item, so the client sees a clear breakdown and your margin stays protected across the whole project.
Is it free for a solo contractor?
Yes, you can start on the free plan with no card. Pro adds your logo and higher limits when you’re ready, which suits sole contractors and small crews.
