Montonio
Bank / A2A PaymentsMontonio is an Estonian checkout company, founded in Tallinn in 2018, that sells online payments and shipping to small and mid-sized ecommerce stores in Estonia, Latvia, Lithuania, Poland and Finland. It began with open-banking bank payments, where the shopper picks their bank in the checkout and pays straight from their account. It now also bundles card and wallet payments, Inbank-funded pay later and financing, payment links and a multi-carrier shipping module. Its payment services run under a Bank of Lithuania payment institution licence held by Montonio Finance UAB. As of October 2026, Baltic merchants pay a monthly plan fee of €11.99, €14.99 or €39.99 before VAT. On top of that, a bank payment costs €0.05 to €0.20 and an EU consumer card costs 1.29% + €0.20 or 1.49% + €0.25, depending on the plan. In November 2025 Montonio began moving card processing from Stripe to Adyen; under Adyen, daily card payouts arrive two business days after the sale. Montonio says it serves more than 8,000 merchants with a team of about 65, and it is backed by Index Ventures. The price list is unusually complete and the bank-payment rates are low. On the other hand, the plans make card acceptance compulsory below the €39.99 tier, the general merchant terms are not published, and every card dispute costs €20, which Montonio's help centre now says is not refunded even if you win.
