Independent contractor invoices: the basics
A clear contractor invoice lists who did the work, for whom, what was done, the amount and when it is due. On contract work the client is often approving your invoice against a purchase order or a budget line, so the easier you make that match, the faster you get paid.
Keep labour and materials separate. It reads more professionally, and it makes it far easier to answer a query about one part of the bill without reissuing the whole invoice.
Reference the job on every invoice
Add the job number, site reference or purchase order number that the client gave you. It takes ten seconds and it is the single biggest cause of invoices sitting unpaid in a shared inbox — accounts teams cannot allocate a cost they cannot match to a job.
If you work through an agency or a main contractor, put their reference in the “Bill to” block along with the trading name so the invoice survives being forwarded internally. If you are VAT-registered, add your VAT number; if not, leave it off entirely.
A few habits that cut payment delays
- Invoice on a fixed schedule — weekly or fortnightly — rather than whenever you remember.
- Keep your rates consistent with the agreed schedule of rates; unexpected figures get queried.
- Attach the signed timesheet or job sheet if the contract requires one.
- Save the PDF somewhere you can find it, alongside your own records for self-assessment.

Frequently asked questions
Do independent contractors need a company to invoice?
No. Contractors and sole traders can invoice under their own name without forming a company.
Should I charge VAT on contractor invoices?
Only if you are VAT-registered. If you are not registered, do not charge VAT or show a VAT number.
Why does a job or PO reference matter?
Accounts teams match invoices to jobs and purchase orders. Without a reference your invoice can sit unmatched and unpaid.
Should labour and materials be separate lines?
Yes. It reads more professionally and makes queries about a specific part of the bill much easier to resolve.
Where is my data stored?
Nowhere. It runs in your browser and is saved only as a local draft on your own device.
