ESSENTIAL WALKTHROUGH

Create an invoice. Set the right payment terms.

Follow the existing invoice workflow, including bank-transfer details or cash already paid on site.

Fictional Oakfield invoice sample
FICTIONAL SAMPLE · NOT A CUSTOMER DOCUMENT
Fictional invoice sample. Original A4 output; additional pages are included in the PDF where needed.

Follow the workflow

  1. Add your business details and, for bank-transfer invoices, your bank information in Company setup.
  2. Open Quotes & invoices and start an Invoice, or create an invoice draft from an issued quote.
  3. Add the customer, work, line items and applicable VAT information. Check the totals.
  4. Choose same-day, 15, 30 or 90-day terms, or a custom due date. For a payment already received in cash, choose Paid by cash on site and record its date; the invoice omits bank details and shows zero balance.
  5. Save while drafting. Review and issue with the paid package or an applicable grant, then download the A4 PDF or send through your connected company email.

Prepare free; issue with the package

Free accounts can save supported drafts. Issuing numbered customer documents and downloading their PDFs requires a paid subscription or an applicable access grant. Sample PDFs shown here are fictional, unsigned examples, not customer records.

Try the full paperwork package for seven days

Try the Essential package free for seven days, with no card details and up to two engineers. Confirm your email, save your real company details and start the trial from Your account. After seven days, a subscription is required for new numbered documents, PDFs and sending. Your saved work is preserved. One trial per company; changing email does not create a new entitlement.

Use a completed certificate as your starting point

Open the certificate in My documents and choose Create quote for this customer or Create invoice for this customer. Essential opens a new draft with the customer name, contact details, property address and certificate reference.

Check that the copied person and address are the correct billing recipient. Add your items and prices, review VAT and payment or validity terms, and save the draft before issuing. Technical findings, signatures and charges are not copied; the original certificate stays unchanged.

Before you choose

Can I return to a draft?

Yes. Save the supported draft in your account and reopen it in the matching workspace. Review the details before issuing; a sample PDF is not an editable draft.
