Should every business use the same invoice template?

The core identity, dates, currency, totals, and payment fields stay consistent, but descriptions, units, and supporting references should match the work.

What units can service invoices use?

Use accurate units such as hours, days, sessions, trips, milestones, pieces, or passengers, depending on how the service was approved.

What references should an invoice include?

Include a relevant quotation, purchase order, job card, delivery note, booking, or contract reference when it helps the client verify the charge.
