Image Consultant Invoice Template

An invoice is a payment instruction, not a receipt for something already settled. Most late payments are caused by an invoice that is unclear, unnumbered, or sent to a person who cannot approve it.

Everything on this page is yours to copy and adapt. The courses cover the decisions behind it: what to charge, what to promise, and what to put in writing.

What yours needs to cover

✓ Your trading name, contact details and any tax registration number that applies
✓ A unique invoice number, sequential, because your accounts and your memory both need it
✓ Invoice date and a due date as an actual date rather than "on receipt"
✓ A description of the work that matches what the client agreed to buy
✓ The amount, any tax, and the total, separated
✓ How to pay, including bank details or a payment link, and what happens if it is late

How to use it

Invoice the deposit at booking and the balance on delivery, not weeks later.
Send it to the person who approves payment, which in a business is rarely the person you met.
Use one numbering series and never reuse a number.
Follow up on the day after the due date, politely and automatically.

Why the invoice decides when you get paid

Private clients usually pay promptly when the invoice is clear and arrives at the right moment. The delays come from invoices sent weeks after the session, invoices with no due date, and invoices that describe the work so loosely the client is not sure what they are paying for.

Corporate clients add a second problem. The person who booked the workshop rarely approves payment, and an invoice without a purchase order number or sent to the wrong inbox can sit untouched for a month. Ask at the proposal stage who receives invoices and what they need to see on one.

Describing the work

Use the same words on the invoice that you used in the agreement. "Wardrobe audit, four hours, with written gap list" matches the scope the client signed, so there is nothing to question. For a package, list each part as its own line even if the total is a single package price, so the client can see what was delivered.

If you sell products such as swatch books or printed guides, keep them on separate lines from your consulting fee. Sales tax can apply differently to goods and to services depending on your state, and mixing them on one line makes that harder to get right.

Deposits, balances and follow-up

Invoice a deposit when the booking is confirmed and the balance on the day of the session or on delivery of the report. For multi-stage private work, invoice each stage as it starts. For corporate work, set the invoicing schedule in the statement of work (commonly a portion at signing and the rest on delivery) and follow it exactly.

Decide your follow-up routine in advance: a friendly reminder the day after the due date, a second one a week later, and a phone call after that. When the routine is written down, chasing a payment stops feeling personal.

Keep every invoice in one numbered series in one place, alongside a note of when it was paid. That record is what your bookkeeping and your tax return are built from, and it also shows you, month by month, how long clients actually take to pay. If corporate work routinely arrives thirty days after delivery, your cash flow plan needs to know that before you take on a large engagement.

Mistakes to avoid

Invoicing weeks later. The longer the gap, the less urgent payment feels to the client. Invoice the balance on the day of delivery.
Writing "due on receipt". It is not a date, so nobody treats it as one. Give an actual due date.
Sending it to the wrong person. In a business the person you met is often not the one who pays. Ask who approves invoices and what reference they need.
Guessing on tax. Whether you need to collect sales tax depends on your state and on whether you sell goods or services. Check before your first invoice.
