How do I accept credit card payments online?
Use an aggregator like Stripe to start, or apply for a dedicated merchant account through an acquirer and connect it to a payment gateway. Growing businesses usually move to a dedicated account.
- How do I accept payments online from other countries: Choose an acquirer that supports international cards and the currencies you sell in, and settle into multi-currency business accounts to avoid repeated conversion.
- What do I need to set up a payment gateway: A registered business, a compliant website with refund and terms pages, ownership and ID documents, bank statements and volume estimates.
- Should I have more than one payment processor: Once card volume is meaningful, a second approved processor protects revenue if one account is reviewed or paused.

1. The three ways to accept card payments online
Aggregators (Stripe, PayPal, Shopify Payments, Square): you are approved in minutes because you share the provider's merchant account. The trade-off is that underwriting happens later, so funds can be held or the account closed once volume, refunds or disputes grow.
Dedicated merchant account (MID) with an acquirer: the acquiring bank underwrites your business before you go live. It takes longer to open, but terms, reserves and limits are agreed up front.
Gateway plus acquirer: a payment gateway handles checkout and card data, and routes transactions to one or more acquirers. This is the setup that lets you add a second processor without rebuilding your checkout.
2. Payment gateway setup, step by step
1. Confirm your company and where it is registered, because acquirers mostly board businesses in the regions they are licensed for (EEA, UK or US).
2. Prepare the website: clear product descriptions, prices, refund and cancellation policy, terms, privacy policy and customer support contacts. Missing policies are one of the most common reasons for decline.
3. Gather the file: incorporation documents, ownership, ID, proof of address, bank statements, recent processing history and an estimate of monthly volume and average ticket.
4. Choose a gateway that supports the acquirers you need and your platform (Shopify, WooCommerce or a custom checkout).
5. Agree pricing, reserve terms, settlement currency and payout schedule before going live.
3. Selling to customers in other countries
To accept payments internationally, look at three things: which currencies you can price in, which currencies you can settle in, and where the acquirer is located. Cross-border card transactions usually carry higher fees than domestic ones, so a European business selling heavily in the US may benefit from US acquiring through a US entity, and the reverse.
Settling in USD, EUR and GBP into multi-currency business accounts avoids converting every payout. Our team can match the processing setup with the right banking rails.
4. Why you need a backup processor
If one provider is your only way to get paid, a single review can stop revenue overnight. Businesses past roughly 30,000 per month in card volume often keep a second acquirer ready, with the gateway able to route traffic between the two.
This is not about getting around a provider's rules. Each account must be opened honestly for the real business, with accurate descriptions and volumes.
