Heating invoice questions
- Can I record service and certificate details?
- Add them as lines or notes; they appear on the finished PDF and stay in the job's history.
- Can I quote a full installation?
- Yes — build a detailed quote and convert it to an invoice when the install is complete.
- Is this invoice generator really free?
- Yes — 3 documents a month free with a small watermark. Pro removes the watermark and adds unlimited documents, saved clients, branding and email sending.
- Are the invoices VAT-compliant for the UK?
- Per-line VAT rates (20%, 5%, 0%), a VAT breakdown by rate, your VAT number and an optional reverse-charge note — the fields HMRC expects.
- Do my invoice numbers stay sequential?
- Yes — each workspace gets a gapless counter (INV-0001, INV-0002…) so your records line up for HMRC and your accountant.
