Online payments
Online payments is the layer that moves money between buyers and sellers across cards, bank transfers, wallets and instant rails. The category is anchored by Visa, Mastercard, PayPal, Stripe, Adyen and Block, with regional scale players (Mollie, Worldline, Nexi, Mercado Pago and Razorpay) covering specific corridors. Global e-commerce payment volume passed $7T in 2024 and continues to grow at high single digits; the action is in shifting share toward platform-led acquirers (Stripe, Adyen) and away from legacy bank-acquirers.
The sector spans merchant acquiring and payment service providers, cross-border and FX payment specialists, digital wallets and pay-now buttons, B2B payments and accounts-payable automation, account-to-account and pay-by-bank, point-of-sale and integrated software payments, real-time payments rails, and card network and processor infrastructure.
Revenue comes from take-rate on transaction volume, FX and conversion spreads on cross-border flows, subscription fees for payment software and platform tooling, monthly platform fees in vertical SaaS, and recurring float income on customer balances at wallets and PSPs.

How online payments companies monetize?
Online payments companies monetize through transaction take-rate, FX and conversion spreads and subscription and platform fees.
Transaction take-rate
Percentage of transaction value retained as net revenue. The dominant model across acquirers and PSPs; Stripe, Adyen, Mollie and Worldline run on this line.
FX & conversion spreads
Spreads on cross-currency settlement. Wise, Airwallex, Currencycloud (Visa) and PayPal X-Border all monetise this line; materially higher margin than domestic processing.
Subscription & platform fees
Recurring monthly platform fees in vertical SaaS and embedded payment programs. Shopify Payments, Toast, Square and Stripe Connect all bundle subscription with transaction revenue.
Wallet float & yield
Interest earned on customer balances held in wallets. PayPal balance, Cash App and Venmo all carry float-sensitive revenue lines.
Network & interchange
Schemes (Visa, Mastercard) earn small per-transaction fees; issuers earn interchange. Together this is the largest single revenue pool in payments and accrues to non-fintech incumbents.
Processing & gateway fees
Per-transaction processing fees on rails (ACH, FedNow, SEPA, Pix). Lower margin than acquiring but very high volume; Fiserv, FIS and ACI Worldwide sit here.

Key online payments KPIs to track
Total payment volume, take rate, net revenue retention and gross margin are the metrics investors track in online payments.
| KPI | Definition |
|---|---|
| Total payment volume (TPV) | Gross dollar volume processed in the period. The headline scale metric for every acquirer, PSP and wallet. |
| Take rate | Net revenue divided by TPV. Adyen runs 18-22bps net; Stripe is structurally higher on the SMB tilt; PayPal Braintree sits in between. |
| Net revenue retention | Existing-customer revenue 12 months later. Adyen targets 110%+ NRR via wallet share gains rather than upsell. |
| Merchants on platform | Active merchants or accounts on the platform. Shopify, Stripe and Adyen all disclose; correlates loosely with TPV by segment mix. |
| Gross margin | PSP gross margins sit at 35-50% after network and interchange pass-through; pure software layer margins (Bill.com, Tipalti) run 70-80%. |
| EBITDA margin | Adyen runs 45-50% EBITDA margin; Stripe is below at investment-mode tilt; PayPal sits at 25-30%. |
| Cross-border share | Cross-border TPV divided by total TPV. The richest segment by take-rate; Adyen and PayPal both disclose. |
| Active accounts | Wallet active accounts. PayPal disclosed 430M+ active accounts at end-2024; Cash App and Venmo report monthly transacting users. |
