Self-billing and RCTIs explained for sellers

If you have sold through GoFindPart, you will have noticed you never raise an invoice yourself — one appears in your account, already correct. That is self-billing, and the document is a Recipient-Created Tax Invoice (RCTI). Here is what it means and why it works this way.

Why GoFindPart invoices for you

GoFindPart is the merchant of record. When a buyer accepts your quote, GoFindPart buys the part from you at your quoted price (plus any tier bonus) and resells it to the buyer. So on that transaction, GoFindPart is your customer.

GoFindPart already works out your payout to the penny. Rather than asking you to re-issue the same number through your own accounting software, GoFindPart raises the invoice on your behalf — a self-billed invoice. It is a long-established, HMRC-recognised way of handling exactly this kind of managed purchasing (see HMRC Notice 700/62).

You authorise this once, when you onboard, by agreeing to the self-billing agreement. It runs on a rolling 12-month basis and either side can end it with 30 days’ written notice.

What the self-billing agreement means in practice

By agreeing to self-billing you accept that:

• You do not issue your own VAT invoices for sales completed through the platform — GoFindPart’s self-billed invoice is the valid VAT invoice for both parties.
• You keep each self-billed invoice for the period HMRC requires. These are your sales invoices for VAT.
• You notify GoFindPart within 14 days of any change to your VAT registration status, VAT number, registered business name or registered address.

How VAT is handled

Your VAT treatment follows the status you give at onboarding:

• VAT-registered sellers: your payout is treated as inclusive of VAT, and the self-billed invoice shows the wholesale price with the VAT reverse-calculated at the standard 20% rate. This preserves your cash position — nothing is added or taken away, the invoice simply presents the VAT element correctly.
• Non-VAT-registered sellers: your sale is outside the scope of VAT. The invoice shows a single subtotal with no VAT line.

Where to find your invoices

Your self-billed invoices are available in the app as a read-only document hub, each with a PDF download. The counterparty on them is GoFindPart Ltd — buyer identity is never shown, in keeping with the platform’s anonymity model. Delivery costs and any platform margin are handled entirely on the buyer’s side; no platform fee is deducted from your payout.
