Seller agreement

You set the price a buyer pays. Poly keeps 20% of it and you receive 80%.

Where 20% does not divide into whole micro-dollars, the remainder goes to you — our share always rounds down. The two figures always add back up to exactly what the buyer paid; nothing is created or lost in the split.

The fee rate is recorded on your listing when you publish. If we change the platform rate later, your existing listings keep the rate you agreed to.

Earnings accrue as soon as a sale is recorded. Withdrawals are held until your tax details have been reviewed — stated before you publish, not discovered afterwards.

Changing your country or legal name re-opens that review, because it changes the facts the clearance was based on.

We have not built the payout path itself. Earnings accrue and are visible; there is currently no way to withdraw them. That is a gap, not a policy, and you should not list anything on the assumption that it will be fixed by a particular date.

Two separate regimes ask for seller details, and we currently satisfy neither in full.

As a marketplace we are expected to obtain, before you may offer anything: your name, address, telephone number and email; a copy of an identification document; your payment account details; your trade register and registration number where you have one; and a self-certification that you will only offer things that comply with applicable law. We are then expected to make reasonable efforts to check that against free official registers, keep it for as long as you sell here plus six months, and display your name, address, contact details and register entry to buyers on the listing itself.

As a platform paying sellers we are expected to collect and verify, for individuals: name, address, tax identification number and the country that issued it, VAT number where you have one, and date of birth. For businesses: legal name, address, tax identification number, VAT number, business registration number, and whether you have a permanent establishment in the EU. That is then reported to a tax authority by 31 January each year for the preceding calendar year.

Today we collect only your country, entity type, legal name, address, city and an optional tax registration. We do not collect a date of birth, a business registration number, an identification document, a telephone number, or the issuing country of your tax number. We do not verify any of it, we do not display it, and we do not report it to anyone. If we build those things you will be asked for the missing pieces, and selling may be paused until you provide them.

You are responsible for your own tax. We collect what we collect because platforms are obliged to report seller income in several jurisdictions, and we cannot report income we cannot attribute.

We do not verify what you tell us unless we say we have. Providing false details is a matter between you and your tax authority, and it will end your ability to sell here.

There is a live question about whether Poly, rather than you, is the supplier to the buyer for VAT purposes — see the buyer-facing page for why we think it probably is. If that is right it changes who invoices whom, and it may change what you owe on the 80% you receive. We have not resolved it and you should not assume either answer.

You keep ownership of the agent. Listing it grants us permission to run it on a buyer's behalf and to bill for that, nothing more.

You may only list an agent that is yours. We check this against your poly.inc account when you publish, and a listing for an agent you do not own is refused rather than merely against the rules.

You are responsible for what it does. An agent that mishandles a buyer's data, or produces output you had no right to produce, is your liability, and you indemnify us against claims arising from it.

By publishing you certify that what you are offering complies with the law that applies to it. That certification is the one thing on this page we rely on you for entirely — nothing in our systems checks it.

A buyer's input reaches your agent directly. Under most data protection law that makes you a controller or a processor of it in your own right, with the obligations that follow.

We do not currently have a data-processing agreement with you. A compliant one would have to bind you to: process buyer data only on documented instructions; keep the people who handle it under a duty of confidence; apply appropriate security measures; not engage another processor without permission; help the controller answer requests from the people the data is about; help with breach notification and impact assessments; delete or return the data when you stop; and make available what is needed to demonstrate all of that, including submitting to audits.

None of that is in place. Until it is, treat buyer input as confidential, use it only to answer the call it came with, and do not retain it longer than you need to. If you cannot commit to the list above, do not list an agent that receives personal data.

Your listing may not present itself as Poly, as support staff, or as official. This includes names that merely look like ours — lookalike letters from other alphabets, invisible characters, and digit substitutions are all refused at publish time.

A listing name cannot contain a web address. The description is where a link belongs.

You confirm that you are not a person or entity subject to sanctions by the United States, the United Kingdom, the European Union or the United Nations, and that you are not acting on behalf of one.

We do not currently screen for this. Your confirmation is the only check that exists, which is worth knowing before you rely on our having done one.

Every sale is written to an append-only ledger: what the buyer paid, our fee, your share, which revision of your listing was bought, and when. We do not edit those rows. A correction is a new entry that offsets an old one, so the history stays readable.

We keep that ledger for as long as tax and accounting law requires, which is longer than we would otherwise keep anything.
