Seeing every payment is free. Booking them is what you pay for.

Free shows every payment and a plain monthly overview per seller. Books makes it bookable: the tax case per seller, the reverse-charge lines, the export your accountant imports, and every receipt and document kept as long as you have the plan.

Does Books get me input VAT back?
Input VAT follows tax law, not our plan. For sellers outside Germany the reverse-charge rule applies and needs no invoice from the seller. For sellers in Germany it needs the seller’s invoice, which a level 3 seller issues through us. Books gives your tax adviser the documents and booking lines for both. This is not tax advice.
Why is there a limit on transactions?
Every payment is a receipt we write, check and keep. The limits keep the price flat for normal use. Very large volumes belong in the plan for large companies.
How do you convert USDC to EUR?
With the ECB reference rate of the payment day, marked provisional on every document until your tax adviser confirms the method. Other methods come as options.
Do you need access to our wallets or keys?
No. Your agents prove their wallets with a signature once. We only read the chain.
We do not need Books. Can we still keep our records with you?
Yes, with the archive for €5 a month or €50 a year. Your receipts, monthly overviews and invoices stay as long as you book it, and the company stays on Free. Without it, the records of a year go on 31 January of the next year, after two notices. You can download everything at any time.

Prices per company, including VAT, paid in advance. A year costs ten months. Changes show up in the changelog before they apply.

The €10 pay for the company check and are included in Books and Books for teams. Invoices in your name come with Books, the same plan a company uses for buying. There is no separate seller plan and no fee per payment.

Listed and verified is free. Invoices in your name come with Books.

Being in the directory and proving your wallet costs nothing. The company check costs €10 a year. Invoices in your name make us responsible for their content, numbering and archive, so they are part of Books.

What does the €10 check cover?
Your entry in the commercial register, your VAT ID in VIES, a DNS record on your domain that ties the service to the company and, where needed, an ID check of the person acting for it. We repeat it every year.
Why not a fee per payment?
We only write invoices for payments from our customers, one per buyer company and month. A fee per payment would punish small prices, and most calls cost a cent or less.
Do you take a cut of what agents pay me?
No. The payment goes from the agent’s wallet to yours. We never stand in the money path and never hold a balance for anyone.
Can I pay for a better place in the directory?
You can book the sponsored tile for €49, one month at a time and paid once. It is marked and sits outside the order. Levels and ranking cannot be bought.

Everything an agent does here is free.

Its wallet pays the sellers it buys from, directly, and nobody else. We read the chain afterwards and write the receipt.

Does my agent need a human to sign up?
No. It pastes one line into its MCP client, proves its wallet with a signature and is in, with a company account of its own. People join later by email.
Will you ever charge agents for receipts?
No. The agent never pays us. What a company pays for is getting the receipts into its books.
What does the 0.001 USDC proof pay for?
Nothing but the proof. Some smart-contract wallets cannot sign a message, so they send a tenth of a cent from themselves instead. The amount stays with us. We do not return dust.
