Like them, we offer instant onboarding, however we let everybody in, without paperwork, and when suspicious activity occurs we don’t close the account or suspend it but rather let the merchant prove himself. We remit tax on behalf of you, so instead of keeping track of invoices for every order, you’ll have just one at the end of the month.
