PhonePe Payment Gateway

Payfac / Aggregator

B-

PhonePe Payment Gateway (PhonePe PG) is the online payments product of PhonePe Limited, the Bengaluru company behind India's most-used UPI app, which is majority-owned by Walmart. It lets Indian businesses take UPI, cards, net banking and wallet payments on a website or app and settles in rupees to an Indian bank account. As of October 2026 the pricing page lists a standard plan at 1.99% per transaction, struck through and shown as free under a limited-period offer, with 18% GST on top of any fee. There is no setup or annual maintenance fee. The page does not say how long the free period lasts or what each payment method costs once it ends. PhonePe Limited signs the merchant directly and collects customer payments into its own designated account before settling them, under a Reserve Bank of India Payment Aggregator authorisation granted in September 2025 and extended to in-store payments in November 2025. The standard terms settle within T+2 working days, let you leave on seven days' notice with no exit fee, and let PhonePe change fees at its discretion and withhold settlements: for up to 180 days if it suspects fraud or a prohibited business, and with no stated time limit after termination or high chargebacks. In September 2025 the RBI fined PhonePe ₹21 lakh after its escrow balance fell short of what it owed wallet holders and merchants on certain days.

PAYONE

Platform / Acquirer

B-

PAYONE is a Frankfurt-based card acquirer and payment service provider for businesses in Germany and Austria. It is a joint venture of Worldline, which holds 60%, and the DSV Group, the payments arm of Germany's savings banks (Sparkassen), which holds 40%. PAYONE GmbH holds the merchant agreement itself and is supervised by BaFin as an e-money institution. It says it serves 277,000 customers and processes over 7.65 billion transactions a year. Small-business prices are published in euros, as of October 2026. Tap on Mobile, which turns a phone into a card reader, has no monthly fee or contract and costs 1.90% per Visa or Mastercard credit card payment and 0.89% per debit card payment, with a €0.15 minimum. Terminal plans run from a pay-as-you-go option with a 24-month device term to flat-rate packages from €29.90 to €44.90 a month on 36- or 60-month contracts. Online plans start at 2.49% + €0.99 with no monthly fee. PAYONE's price list says all fees are subject to VAT. Fixed-term contracts renew for 12 months unless cancelled three months before the end. The main concern is regulatory: in 2023 BaFin barred PAYONE from processing transactions for certain merchants in a high-risk e-commerce portfolio, in January 2025 it announced higher capital requirements and a special representative, and in December 2025 it announced fines totalling €95,000 over anti-money-laundering failings.

Givebutter

Payfac / Aggregator

B

Givebutter is a US fundraising and donor CRM platform run by Givebutter, Inc., whose executives are based in Austin, Texas, with an all-remote team. Max Friedman, Liran Cohen and Ari Krasner started it in 2016 while at college. It sells donation forms, fundraising pages, ticketed events, auctions, peer-to-peer campaigns, a donor CRM with email and text, a mobile app with Tap to Pay and card readers, and a Stripe-powered Wallet account with Visa spend cards. Every organisation is onboarded to a Stripe Connect account through Givebutter, and Givebutter sets the fees, holds campaign balances, approves payouts and handles disputes. As of October 2026, accounts created since 9 September 2025 have two choices per campaign. With donor tips switched on, Givebutter charges the organisation nothing: donors are asked to cover a 2.9% + 30 cent processing fee and to tip Givebutter, and under its Guarantee, Givebutter absorbs any processing fee they decline. With tips switched off, a flat 3% platform fee applies, plus 2.9% + 30 cents for cards (1.9% + 30 cents for ACH). Givebutter Plus adds automation and phone support from $29 a month billed annually. Payouts are withdrawn by hand and, according to the help centre, take 3 to 5 business days; the pricing page says 2 to 3. The tip model is under legal challenge: two proposed class actions filed in 2026 allege that Givebutter preselects tips and processing fees on donors' behalf without proper consent. Both are pending.

Ecommpay

Platform / Acquirer

B-

Ecommpay is a London-based online card acquirer and payment platform. Its UK entity, Ecommpay Limited, is authorised by the Financial Conduct Authority as a payment institution (FRN 607597) and is a principal member of Visa and Mastercard, so it holds the merchant agreement itself rather than reselling a bank's. EU merchants are served by a sister company under common ownership, ECOMMBX LTD, a Cyprus e-money institution that uses the Ecommpay trademark under licence. Most of Ecommpay's business is quoted, custom pricing for mid-market and enterprise online merchants in travel, digital goods, financial services, mobility and retail. It also publishes a rate card for UK micro-businesses, dated 23 October 2025 and still the version on its site in an archived copy from 5 October 2026: 1.30% + £0.20 on UK consumer cards and 3% + £0.20 on international consumer cards, with no setup or monthly fee, no fixed term, and settlement five business days after each day's batch. Extra fees apply for currency conversion (2.5%), declined authorisations (5p), refunds (50p) and chargebacks (£15). The company is privately held and controlled by its founder, Aleksejs Sjarki, through a Cyprus holding company. Its public review footprint is small but positive. A 2021 article by the Russian outlet The Bell, citing three unnamed sources, named Ecommpay as one of the biggest players in the late-2010s cross-border payments market that it said moved illegal online-gambling money out of Russia. We found no regulator or court finding, lawsuit or enforcement action naming the company.

Donorbox

Platform / Acquirer

B

Donorbox is a US donation and fundraising platform run by Rebel Idealist Inc., a Delaware corporation based in Alexandria, Virginia. Founder and CEO Charles Zhang started it in 2014 as a free WordPress donation plugin. It sells donation forms, fundraising and crowdfunding pages, peer-to-peer campaigns, event ticketing, memberships, a donor CRM, text-to-give and an in-person kiosk app. Donorbox does not process payments itself. Each organisation connects its own Stripe or PayPal account, donations land in that account, and Donorbox takes a platform fee on top of the processor's fee. As of October 2026 the free Standard plan charges a 2.95% platform fee on donation forms and pages and 3.95% on events, memberships and supporter peer-to-peer pages. Pro costs $150 a month and lowers those to 1.75% and 2%. Premium is quote-only, with platform fees of 1.6% to 2%. Processing is extra: Donorbox quotes 2.2% + 30 cents for US nonprofits on Stripe's discounted rate, and 2.9% + 30 cents for other organisations. Donors can choose to cover the fees. There is no contract or setup fee. Payouts follow the Stripe or PayPal schedule, every two business days by default for US Stripe accounts. In June 2026 Donorbox said more than 100,000 organisations had raised over $4 billion through it. Trustpilot shows a 4.3 TrustScore, but 26% of its 106 reviews are one-star.

Creem

Merchant of Record

B-

Creem is a merchant of record for software, SaaS, AI tools and digital downloads, run by Armitage Labs OÜ, a company registered in Tallinn, Estonia in April 2024. Creem is the legal seller on every sale. It charges your customer, issues the invoice, and calculates and remits VAT and sales tax, then pays you what is left. As of October 2026 the published price is 3.9% + $0.40 per successful transaction, with no monthly or setup fee and no separate international card fee. Some costs sit outside that headline. Bank payouts cost $7/€7 or 1% of the payout, whichever is higher. USDC payouts cost 2%. Each chargeback costs $25 or €25, and revenue splits and the affiliate program add 2% each. Payouts go out only on the 1st and 15th of the month, after you request them, from a balance of at least $50 or €50. Creem's documentation says sales are held for 7 to 12 days for risk review before they can be paid out. The product range is broad for a young company: subscriptions, usage-based billing, prepaid credit wallets, license keys, affiliates, revenue splits and an agent-friendly API, CLI and MCP server. Acceptance is the weak point. Creem screens every store before it can take live payments, keeps a long prohibited list, and may withhold payouts under wide terms. On Trustpilot about half of the reviews are one-star, and most of those come from merchants who were rejected, suspended or had funds held.

Yuno

Gateway / Orchestration

B-

Yuno is a payment orchestration platform for large merchants, banks and wallets. It started in Latin America and now sells worldwide. It does not process payments or hold funds itself. You sign your own contracts with payment processors, acquirers, wallets and fraud tools, enter their credentials in Yuno's dashboard, and Yuno routes each transaction between them through one API. It retries failed payments on another provider and stores card tokens in its own vault. Yuno says it connects to more than 1,000 payment methods and over 460 integrations in 190+ countries. Named customers include McDonald's, Rappi, NetEase Games, GoFundMe and inDrive. It raised a $45 million Series B in August 2026, led by Global PayTech Ventures with Andreessen Horowitz and Tiger Global taking part. Yuno publishes no prices. Its public merchant terms describe a fixed monthly platform fee plus per-transaction fees for successful payments, payouts, refunds and verifications, with extra fees for add-ons such as 3-D Secure, fraud checks and chargeback alerts. Contracts run for a fixed term set in an order form, renew automatically unless you give 60 days' notice, and leaving early means paying the remaining monthly fees for the term. There is almost no independent user feedback to check its claims against.

Paytm Payment Gateway

Payfac / Aggregator

B-

Paytm Payment Gateway is the online payments business of Paytm Payments Services Limited (PPSL), a wholly owned subsidiary of One 97 Communications, the listed company behind the Paytm brand. It lets Indian businesses take UPI, cards, net banking, EMI and wallet payments on a website or app, and settles in rupees to an Indian bank account, by default the next day. As of October 2026 the standard plan is 1.99% per transaction with 18% GST on top, no setup fee, and custom pricing for large businesses. PPSL is a Reserve Bank of India-authorised Payment Aggregator: it signs the merchant, pools customer funds in an escrow account and settles them, which makes it a payment facilitator rather than a bare gateway. That authorisation came late. The RBI turned down PPSL's first application in November 2022 and barred it from onboarding new online merchants. The bar was lifted with in-principle approval in August 2025, and the full certificate followed on 26 November 2025. Offline and cross-border authorisations were added on 17 December 2025. The RBI action that closed Paytm Payments Bank, which ended in the cancellation of its banking licence on 24 April 2026, concerned a separate group company and not PPSL. The product is broad and built for scale. The published merchant terms, however, list fees that are hard to reconcile with the one-line pricing page, and they favour Paytm on fee changes, withheld settlements and liability.

eProcessing Network

Gateway / Orchestration

C+

eProcessing Network (ePN) is a payment gateway run by eProcessing Network, LLC in Houston, Texas, and has been online since at least 2000. It is not a processor and does not offer merchant accounts. You need a merchant account with an acquiring bank, and ePN connects your website, virtual terminal, POS software or mobile app to that account through processing platforms including Fiserv's First Data, TSYS, Global Payments, Elavon, Chase Paymentech, Worldpay and EPX. It also connects to several ACH, check and gift card providers. ePN sells only through resellers: ISOs, merchant service providers and their agents. It publishes no prices. Its own merchant service agreement has blanks for a monthly gateway fee and a per-transaction fee, so what you pay depends on the reseller. The product range is broad and practical for a small US merchant: an online terminal, hosted order and payment forms, a shopping cart, an Authorize.Net emulation mode (on some processor platforms), recurring billing, invoicing, customer storage, Level III data, QuickBooks sync, Windows POS software and a mobile app. Fraud filters are included with every gateway account. The tooling looks dated, and the company has posted no news since March 2023. Support was the weak point in July 2024. Hurricane Beryl and the CrowdStrike outage hit together, and BBB complaints from that month describe unanswered calls and batches that did not settle, and two later complaints describe billing that continued after merchants asked to cancel.
