How to Invoice Art Collectors and Galleries (With a Free Template)

What an Artwork Invoice Needs

A collector or gallery reading your invoice should be able to tell, at a glance, exactly what they are paying for. That means:

• Your studio name, contact details, and a unique invoice number
• Issue date, due date, and the collector or gallery's billing details
• Artwork title, medium, dimensions, and edition number where relevant
• Line-item price, subtotal, tax or VAT where it applies, and the total
• Currency and clear payment instructions
• Any agreed deposit, balance due, or reference number

Tax and invoicing requirements vary by country and by sale type, so check what applies to your own business before you send anything.

Invoicing Collectors vs. Galleries

A direct sale to a collector is usually the simplest case: one invoice, one buyer, one artwork or a small group of works. A gallery consignment sale is different — you are often invoicing the gallery for their cut after a sale closes, not the end collector directly, and the gallery's own paperwork may reference a separate consignment agreement and commission split.

Keep a consistent record either way: which artwork, which party, what was agreed, and what has actually been paid. That record is what makes a follow-up email possible months later without digging through old emails.

Certificates of Authenticity and Following Up

For anything beyond a small print or study, collectors increasingly expect a Certificate of Authenticity alongside the invoice — a signed statement tying the specific work to you as the artist. Keep the invoice and the COA linked to the same artwork record so you are not reconstructing details from memory if a collector resells or insures the piece later.

Late payment is common enough in this business that a plain, non-awkward way to follow up matters. A tracked invoice status (sent, viewed, paid) makes that follow-up a fact, not a guilt trip.
