Payment Gateways
Getting paid is not a checkbox at the end of the build. It is currencies, local methods, taxes, chargebacks and a reconciliation that has to match the bank.

Payment integration at Sell with Marketing means connecting and configuring the processors your market actually uses: Stripe, PayPal, Mercado Pago and the local methods a buyer expects to see, plus subscriptions and instalments, multi-currency pricing, tax handling by country, and reconciliation between what the platform reports and what reached the bank.
Nothing in a company is more expensive than a checkout that fails at the last step. The customer decided, pulled out a card, and the transaction was declined for a reason nobody investigated. We have found stores with money stuck in the cart while every report looked healthy, because a corrupted tracking pixel had made the failure invisible.
Selling across borders makes it harder. A buyer in Mexico expects instalments and OXXO, one in Germany expects SEPA and invoice, and one in the United States expects a card and nothing else. A gateway that only offers what works in one of those quietly loses the other two.
From the button to the bank statement.
- Processor selection and configuration: Stripe, PayPal, Mercado Pago, Conekta or the local processor, chosen for your market and your ticket size rather than for whichever has the nicest documentation. Set up in your own account, in your name.
- The local payment methods your market expects: Instalments and cash payment in Mexico, SEPA and invoice in Germany, bank transfer and digital wallets where they matter. A checkout offering only what works elsewhere is a checkout that converts elsewhere.
- Subscriptions, plans and recurring billing: Recurring charges with plan changes, proration, failed-payment retries and dunning, because a subscription that cancels itself on the first declined card is a subscription that leaks revenue every month.
- Multi-currency, taxes and invoicing: Pricing per market, tax applied by country, and the connection to your invoicing so a sale does not have to be re-entered by hand.
- Checkout measurement, including the failures: Server-side events for the whole flow, including declines and their reason. A payment that fails silently is the most expensive event on your site and usually the only one nobody is tracking.
- Reconciliation against the bank: What the platform reported, what the processor settled, what arrived net of fees. The report that reveals whether the commission you are paying is the commission you were quoted.
When the money does not arrive and nobody can say why.
- Companies selling internationally with one payment method for every market
- Businesses whose checkout drops customers at the final step with no diagnosis
- Manufacturers moving from invoice-and-transfer to online payment
- Subscription businesses losing customers to failed cards nobody retries
- Exporters needing to charge in several currencies with local taxes
- Teams reconciling platform, processor and bank by hand every month
The processor account is set up in your name with your own contract and your own commercial terms. We do not intermediate your money, and any supplier who wants to is a dependency you should be very slow to accept.
Before you sign.
Which gateway is best?
It depends on your market and your ticket, not on a ranking. Stripe has the best developer experience and is not always the cheapest, nor is it available on the same terms everywhere. Mercado Pago converts better in much of Latin America because of instalments. PayPal still carries trust in cross-border sales. The Diagnostic compares the real commissions against your actual volume and ticket size, and that comparison sometimes contradicts the popular answer.
Whose account are the payments processed in?
Yours, with your own contract with the processor and your own commercial terms. We configure and integrate it; the money moves from your customer to your account without passing through ours. Be careful with any supplier proposing otherwise, because it means your revenue depends on their continued goodwill.
Our checkout loses customers at the last step. Can you find out why?
That is usually the first thing we measure, and the answer is normally one of a short list: a payment method the market does not use, a form asking for data the buyer will not give, a decline whose reason nobody reads, or a tracking failure making the problem invisible. The Diagnostic instruments the funnel and reports where it breaks, with the number attached, before anyone proposes rebuilding anything.
Can we accept payment on credit terms, like our distributors expect?
Yes, and for B2B it is often mandatory rather than optional. Purchase orders, 30-, 60- or 90-day terms and credit limits per customer are configured in the store, alongside card payment for whoever prefers it. Forcing an industrial buyer to pay by card at checkout is how a B2B store ends up unused.
What about chargebacks and fraud?
Both are configured as part of the integration: the processor's fraud rules tuned to your risk profile, evidence captured automatically so a dispute can be answered, and alerts when the rate moves. What is not on offer is a promise of zero chargebacks. Anyone making that promise is describing a filter so aggressive it will also be rejecting real customers.
LET THEM PAY
THE WAY THEY PAY.
It starts with the Diagnostic: what standing still is costing you, what fixing it costs, and what gets fixed first — in your own data. Paid work, credited 100% against the fix if you move within 90 days.
