Presenting professional fees
Consulting clients expect a clear, well-presented bill. Describe the engagement on each line — "Strategy review — 4 days @ £800" reads better than a single lump sum. Add your logo and reference the engagement or PO number in the notes so it routes through the client's finance team without friction.
VAT and retainers
Most established consultants are VAT registered — the tool shows the VAT and the gross total automatically. For a recurring retainer, reuse the same details each month and just change the period and invoice number. Not yet registered? See whether you need to charge VAT and leave it off until you are.

Frequently asked questions
How do consultants invoice clients?
Itemise the advisory work (days, engagement or retainer) with amounts, add your details and the client’s, a unique invoice number, the date, the total and payment terms. Add VAT if you are registered.
Should I reference a purchase order on the invoice?
If the client gave you a PO number, include it — corporate finance teams often will not pay an invoice that omits it. Put it in the notes or alongside the invoice number.
Can I invoice a monthly retainer?
Yes. Reuse the same line and details each month, change the period and use a new sequential invoice number so your records stay tidy.
