The Zinn Digital® marketplace
Eight storefronts on one engine. Every order is held until the work is delivered and you have accepted it, and every seller is checked before their first listing goes live.

Held until you accept
We take the payment and hold it. The seller is not paid when they say they are finished — they are paid when you have seen the work and accepted it.
You buy from us
Zinn Digital® is the merchant of record on every marketplace sale, so you get one invoice from a UK company with VAT handled correctly, not a receipt from a stranger.
Every seller is checked
Identity and bank details are verified before a seller can be paid anything, and a seller who breaks the rules is suspended, not warned.
Every listing is read
Every listing is checked against a published content policy before it appears. Anything the check flags waits for a person, and our team reviews listings that go live and takes down any that break the policy.

Questions people ask before buying
- What happens if the seller does not deliver?
- You are not out of pocket. We hold the money until you accept the work, so if it does not arrive, or it is not what was described, you can request changes or raise a dispute and we step in before anything is released.
- How can I pay?
- Card, Apple Pay or Google Pay, PayPal or cryptocurrency, in your own currency. It is the same checkout as the rest of the platform, and you get a single VAT invoice from Zinn Digital® because we are the merchant of record.
- How do you stop bad listings?
- Two ways. Every seller is identity-checked before they can be paid, and every listing is read by a person against a published content policy before it goes on sale. Editing a live listing sends it back to be checked again.
- How do I sell here?
- Open a Zinn® account, go to Sell, and submit your first listing. You do not need to host with us. Once it is approved it is on sale, and you are paid after the buyer accepts the work.

Sell on the Zinn® marketplace
Sell links, placements, services, sites or domains to the people already hosting with us. You do not need to be a Zinn® hosting customer. We handle the checkout, the invoice and the VAT, hold the buyer's money until they accept, and pay you out — you keep 85% of every sale.
