As a merchant, you grant Peecho a license to print and sell your documents. So technically, the final products will be sold from The Netherlands by Peecho, even though the actual factories may be in another country. As a result, Peecho will fulfill the VAT obligations in The Netherlands, so you don't have to. In short, merchants do not have to register for VAT purposes in the EU.
If you choose to use your own payment service in conjunction with our API, then it might be more complicated. In that case, we are a supplier to you and the normal rules for suppliers apply - there are several material and formal VAT obligations in The Netherlands, like an obligatory VAT registration and VAT reporting. This may lead to additional administrative costs. In general, we advise to let us handle the payment instead.
By the way, for hardcover books, paperbacks and magazines, the Dutch VAT rate is only 6 percent. The rest comes in at 19 percent.
