E-commerce México 2026: real fee comparison — Stripe vs Mercado Pago vs Conekta

Mexican e-commerce closed 2024 at $789.7B MXN per AMVO's 2025 Online Sales Study — a 20% YoY jump from $658B in 2023. Payment gateway is the most expensive and least analyzed stack decision: charges you 3.5%–4.5% per sale and the difference compounds brutally.

Verified fees (June 2026)

Stripe — SaaS and international D2C favorite

Pros

• Best developer experience in the market. Docs, sandbox, clean webhooks.
• Native subscriptions (Stripe Billing) — key for SaaS and memberships.
• Supports USD, EUR, GBP — only viable option if you sell to tourists in Riviera Maya.
• Stripe Link saves method for 1-tap checkout.
• Radar (ML anti-fraud) very good by default.
• Apple Pay and Google Pay ready.

Cons

• OXXO/SPEI integrated but less polished UX than local competitors.
• Limited Spanish support — chat works, email is slow.
• Refunds to Mexican cards take 5–10 days (not Stripe's fault but happens).
• No native MSI — you build them via bank promotions.

Mercado Pago — king of the Mexican mass market

Pros

• Integrated MSI 3, 6, 9, 12, 18 months — key in LATAM (60% of e-commerce ≥$2,000 MXN uses MSI).
• 30M+ active accounts in México — "Pay with Mercado Pago" button converts better.
• OXXO Pay with native UX, link and QR.
• Fast settlement (next business day for many volumes).
• 24/7 Spanish support.
• Official plugins for WooCommerce, Shopify, Magento, Tienda Nube.

Cons

• Less clean API than Stripe. Webhooks sometimes unpredictable.
• International payments out — doesn't accept non-MX cards confidently.
• Funds withheld 14–30 days for new accounts until history builds.
• "Mercado Pago" branding on checkout doesn't work for premium brands.

Conekta — Mexican, middle balance

Pros

• Founded in México, strong local support and direct mid-market relationships.
• Native MSI like Mercado Pago.
• Cash payments at OXXO, 7-Eleven, Walmart, Soriana — widest network.
• Own anti-fraud + tokenization (PCI Level 1).
• Well-designed hosted and embedded checkout.
• Fees negotiable from ~$200,000 MXN/mo volume.

Cons

• Smaller community — fewer plugins, fewer tutorials.
• MXN only.
• Apple/Google Pay not as polished as Stripe.

Real math: $500,000 MXN/mo in sales

Store with AOV $850 MXN (588 tx/mo), 85% cards, 15% OXXO. Estimate using published rate cards (no negotiation):

Gap between most and least expensive is ~$90,000 MXN/year at this volume. But choosing badly goes beyond fees: a gateway without MSI can drop conversion 8–15% on tickets >$1,500 MXN (which destroys any fee savings). To skip the trial and error, this is how we integrate e-commerce and payments with the right gateway for your average ticket.

How to choose without regret

1. If you sell only in México with high ticket ($1,500+): Mercado Pago or Conekta for MSI.
2. If you sell to tourists (Riviera Maya, BCS): Stripe for native USD.
3. If you sell SaaS or B2B subscriptions: Stripe, no hesitation.
4. If you sell low-ticket ($50–$300) at volume: Openpay for lower fixed fee.
5. If you don't want to lock-in: offer two checkout options — boosts conversion ~6% on average (Baymard 2024).

Expensive mistakes we keep seeing

• Enabling MSI without realizing fees go up 2–3%. Use them selectively.
• Not enabling 3DS — chargebacks 4× higher and Visa/Mastercard can fine you.
• Webhooks without signature validation — basic vulnerability we find monthly.
• Forgetting automated CFDI invoicing — SAT fines over $20,000 MXN/mo.
• Reserving prices in MXN when the customer is paying in USD — huge FX error.

Frequently asked questions about gateway fees in México

How much does Stripe charge per transaction in México?

Stripe México's published rate is 3.6% + $3 MXN per domestic card transaction (VAT included in the published rate). International cards add +1.5% and currency conversion +2%. OXXO and SPEI share the same 3.6% + $3 MXN base rate.

Which is cheaper, Stripe or Mercado Pago?

On public rate cards, Stripe (3.6% + $3 MXN) is cheaper than Mercado Pago (4.49% + VAT for single payments) for mid and high tickets. For a store doing $500,000 MXN/month the gap is roughly $6,000 MXN per month. Mercado Pago wins when you need interest-free installments and your customers are 100% domestic: the extra conversion offsets the fee.

What fee does Mercado Pago charge per sale in 2026?

Mercado Pago publishes 4.49% + VAT per single-payment card charge; with interest-free installments the fee rises with the term. Above ~$200,000 MXN per month the percentage is negotiable and we have seen 3.0–3.3% for mid-market merchants.

How much does Conekta charge per transaction?

Conekta's base plan is 4.49% + $3 MXN per card payment, plus VAT on top of the fee. OXXO Pay carries a flat $17 MXN per payment. It is the local option with the best OXXO UX and solid support for interest-free installments.

Which gateway should I use if I sell to tourists in Riviera Maya or Los Cabos?

Stripe, no contest: it is the only one of the three with native USD, EUR and GBP, Apple Pay and Google Pay ready, and Radar anti-fraud by default. You charge in the tourist's currency and settle in MXN or USD, avoiding a double exchange.

Can I run two gateways at the same time?

Yes, and we recommend it when your customer mix is split: for example Stripe for international cards and Mercado Pago or Conekta for domestic interest-free installments. Offering two options at checkout lifts conversion by about 6% on average according to Baymard.
