Toss Payments

Payfac / Aggregator

B-

Toss Payments is the online payment gateway (PG) business of Viva Republica, the company behind South Korea's Toss finance app. It began as LG Uplus's electronic payments division, which Viva Republica agreed to buy in December 2019. LG Uplus spun the division off as a new company in August 2020, after postponing a planned 1 June split, and it launched as Toss Payments on 3 August 2020. It is headquartered in Gangnam, Seoul, and serves Korean online businesses. It also offers PayPal and overseas-card acceptance for selling abroad. As of October 2026 the published price is 3.4% on credit and debit cards for merchants on the general tier, 2.0% on bank transfers (minimum ₩200) and ₩400 per virtual-account payment, all plus 10% VAT. On top of that comes a ₩220,000 joining fee and a ₩110,000 annual fee. Smaller merchants that qualify under Korean law get preferential card rates applied automatically. Contracts run for two years and renew automatically for two more unless either side gives written notice a month before the end. In July 2026 Viva Republica filed a decision to absorb Toss Payments by merger, with a scheduled merger date of 30 November 2026, subject to regulatory approval. Toss Payments will then cease to exist as a separate company, and its contracts pass to Viva Republica, which said in the filing that it has no plans to change or discontinue the business. It has not said whether the Toss Payments name will continue. In September 2026 Toss Payments disclosed that 4,131 payment records from one merchant had been viewed without authorisation, and the Financial Supervisory Service opened an on-site inspection.

Przelewy24

Platform / Acquirer

B

Przelewy24 is a Polish online payment gateway run by PayPro S.A. of Poznań, a national payment institution supervised by Poland's financial regulator, the KNF. The Danish group Nets took control of PayPro in 2019, Nets merged into Italy's Nexi in 2021, and Nexi's June 2025 report lists PayPro as wholly owned. It gives a Polish online shop the payment methods Polish shoppers expect in one integration: BLIK, pay-by-link bank transfers, Visa and Mastercard cards, Google Pay and Apple Pay, plus instalments and buy-now-pay-later through partners. As of October 2026 the standard fee for BLIK, bank transfers and PLN card payments is 1.29% + PLN 0.30 per transaction, with VAT added where the law requires it. There is no monthly fee, refunds are free, and the PLN 59 activation fee is refunded once you complete 10 transactions in your first two months. Funds are available by the end of the next business day, and four PLN payouts a month to a Polish bank account are free. The contract has no fixed term and either side can end it on one month's notice. Pricing and terms are unusually well published. The weak points are payments outside Poland, which cost more and need foreign-currency accounts, broad rights to hold funds (up to 180 days on card transactions under review), a PLN 100 fee it can charge on each chargeback, and a Trustpilot score of 1.3 that is mostly payer complaints but includes merchants describing frozen funds and slow verification.

Primer

Gateway / Orchestration

B-

Primer is a London payments orchestration company founded in 2020 by former Braintree staff Gabriel Le Roux and Paul Anthony. It does not process payments itself. A merchant connects its own accounts with processors such as Adyen, Stripe or Braintree, and Primer sits on top: one checkout and API, a card vault that is independent of any one processor, no-code workflows that decide where each payment goes, automatic fallback to a second processor when the first declines, 3D Secure, network tokens, and reporting and reconciliation across every provider. Newer add-ons include an AI assistant called Companion, a fee breakdown tool called Costs Overview, and Global Accounts for holding and converting currencies, which Primer provides through a partner. Primer publishes no prices. As of October 2026 there is no pricing page; fees are set in a signed order form, charged on billable events such as payments, settled transactions, 3DS checks or workflow actions, and topped up to a minimum commitment if usage falls short. The contract runs for a minimum term and then renews for a year at a time unless you give 30 days' notice. Primer raised a $100 million Series C in May 2026 and says it has raised $174 million in total. It is built for mid-size and enterprise merchants running more than one processor, not for small businesses looking for a first card account.

Vipps MobilePay

Platform / Acquirer

B

Vipps MobilePay is the bank-owned Nordic mobile wallet formed in November 2022 when Norway's Vipps and Denmark's MobilePay merged. It is the payment app most consumers in Norway and Denmark already carry, and a large one in Finland, so for a Nordic business it is less a choice of processor than a payment method customers expect to see. The merchant agreement is signed directly with Vipps MobilePay AS, a Norwegian e-money institution supervised by Finanstilsynet, with branches in Copenhagen and Helsinki. Prices are published per country and charged per transaction, with no monthly fee for the payment products. As of October 2026 online payments cost 2.99% + NOK 1 in Norway, 0.59% + DKK 1 in Denmark (rising to 0.89% + DKK 1 on 1 January 2027) and 2.49% + EUR 0.20 in Finland; in-person payments through a Vipps/MobilePay number or the mobile point-of-sale cost 1.75% in Norway and Finland and 0.99% in Denmark. The merchant terms exclude VAT unless stated. There is no fixed term: either side can end the agreement on two months' notice. Funds settle daily by default. The weaknesses are scope and reputation. It is a Nordic wallet, not a general card acquirer, it sold its multi-method Checkout product to Kustom in 2026, and consumer reviews on Trustpilot are poor. MobilePay will be renamed Vipps in Denmark, Finland and Greenland on 12 January 2027.

Stone

Stone is the small and mid-size business brand of StoneCo, the Nasdaq-listed (STNE) Brazilian payments and banking group. The merchant agreement is with Stone Instituição de Pagamento S.A., which the Banco Central do Brasil authorises as a card acquirer (credenciadora) and e-money issuer. Stone sells card terminals (maquininhas), a tap-on-phone app called TapStone, payment links, e-commerce processing, a free business account (Conta PJ) and working-capital credit. As of October 2026 it publishes some rates: TapStone at 0.87% for debit and 1.90% for one-off credit (crédito à vista), and payment links at 2.99% for one-off credit. Terminal rates are personalised: the terminal page advertises debit from 0.74% and credit from 2.99%, and you get your own rates after an assessment. The contract has no fixed term and the merchant can end it on 30 days' notice without penalty. StoneCo's cheaper micro-merchant brand, Ton, is a sibling sold separately, with its own published plans.

Pine Labs

Payfac / Aggregator

B-

Pine Labs is an Indian merchant payments company based in Noida. It began in 1998, is best known for the card terminals found at Indian shop counters, and has listed on the NSE and BSE since 14 November 2025. It rents in-store terminals and UPI soundboxes, runs an online payment gateway called Pine Labs Online (formerly Plural), and offers debit and credit card EMIs at the till through partner banks and brands. Its other lines include payouts, cross-border card acceptance and prepaid gift cards. The Reserve Bank of India lists Pine Labs Limited as an authorised payment aggregator for online, physical and cross-border (inward and outward) payments. Pricing is the weak spot. As of October 2026 the online gateway shows only 0% MDR on UPI and asks you to contact sales for everything else. Terminals carry 'starting at' monthly prices from ₹75 to ₹450, but the page does not say whether GST is included. Online payments settle T+1 by default, with early-batch and same-day settlement available. The published online terms have no fixed term, but they let Pine Labs hold 30% of payouts for 15 days after either side gives notice to end the service, and 100% for up to 120 days after a breach. Merchant complaints describe rental charges that continued after a terminal was surrendered, charges merchants say were not disclosed at sign-up, and delayed settlements.

Telr

Payfac / Aggregator

B-

Telr is a Dubai-based online payment gateway for small and mid-size merchants in the UAE and Saudi Arabia, with tailored-price service in Bahrain and Jordan. It says it was established in 2014. In March 2025 it announced a Retail Payment Services licence from the Central Bank of the UAE. In the UAE it signs merchants up under its own agreement and pays out their funds, so it works as a payment facilitator. As of October 2026 its UAE price table has four tiers set by monthly sales. Under AED 10,000 a month you pay a flat AED 249 and no listed per-transaction fee. Above that, rates run from 2.45% + AED 1 down to 2.25% + AED 0.50, with monthly fees falling from AED 199 to zero. International cards add 0.50%. Everything is subject to 5% VAT. Saudi plans are priced in riyals, from 3% + SAR 1 on credit cards and 1% on mada, plus 15% VAT, and run through partner banks. The product covers hosted checkout, payment links, invoices, QR codes, Apple Pay, Google Pay, mada, STC Pay and Tabby instalments. Indian payments firm Cashfree Payments put $15 million into Telr in 2021, which Cashfree says made it one of Telr's largest shareholders; one Indian outlet reported it as a majority stake. There is no fixed term, but you must give a month's notice to leave, and Telr can hold a reserve for at least seven months after you close. Public reviews are few and negative.

Satispay

Platform / Acquirer

B

Satispay is a Milan-based mobile payment network. Shoppers pay from the Satispay app instead of with a card, and merchants accept those payments through a free business account, with no card terminal. It is not a card acquirer. The merchant contract is with Satispay Europe S.A., an electronic money institution licensed in Luxembourg (CSSF register W00000010), which credits payments to the merchant's e-money account and sweeps them to the merchant's bank. As of October 2026, physical stores that sign up from September 2026 pay nothing on payments under €10 and 0.95% on payments of €10 or more. Tobacconists and newsagents pay 0.5% at €10 and above. Online payments cost 1.5%, plus €0.20 from €10, and vending machines pay 1%. Sign-up, payouts and cancellation are free, and the terms have no fixed term or exit fee. Optional Business Premium plans for visibility and loyalty run from €5.99 to €299.90 a month. Satispay says it has 6.5 million users and more than 450,000 merchants. Its website serves Italy, France and Luxembourg, but the user base is overwhelmingly Italian. The main caveat is pricing stability: in April 2025 Satispay replaced free sub-€10 payments with a flat 1%, which drew protests from bars and tobacconists. It reversed that change for new merchants from September 2026; existing merchants were told their updated terms by email.

Kushki

Platform / Acquirer

B-

Kushki is a Latin American payments company founded by Ecuadorians Aron Schwarzkopf and Sebastián Castro. It began as an online payment gateway and now calls itself the region's first non-bank regional acquirer. In October 2023 it announced regulatory approval to acquire card payments in Mexico, Chile, Peru and Colombia, with principal Visa and Mastercard membership in those four countries. It also serves merchants in Ecuador. It sells to large online merchants and to payment service providers (PSPs): card and alternative-method collection through an API, hosted checkout and payment links, payouts, and card-present terminals in Mexico and, since a May 2026 launch, Chile. Pricing is quoted per account. The general terms set a default minimum of USD 1,000 a month in fees, and the only rate card we found is the one its Chilean operator publishes on its regulatory-compliance page. As of October 2026 that card shows 2.0%–2.95% for credit, 1.0%–2.0% for debit and 2.90%–3.00% for international cards, plus VAT, with a USD 15 chargeback fee. Contracts run indefinitely and either side can end them on 30 days' notice, but Kushki can hold reserves and change fees on 30 days' notice. In March 2026 Chile's financial regulator, the CMF, fined the Chilean operator UF 300 for late regulatory reporting and for not reporting an October 2024 outage. There is almost no public merchant review base to judge service by.
