# Payments in Mexico: SPEI, fees and MXN settlement

A fast transfer does not automatically mean fast access to your revenue. For Mexico, compare three things together: how the customer pays, what a successful transaction costs and when your business can use the funds.

PayStar's historical snapshot contains **46 Mexico offer records**. This guide turns their stated fees and settlement terms into practical questions for a gateway discussion about your product.

## 46 offers: start with your payment use case

The snapshot of 14 September 2026 contains **29 pay-in and 17 payout offers**. These are distinct offer records, not a count of independent providers or confirmed integrations. Several records may belong to the same gateway.

All 46 records carry an MXN label; 30 carry SPEI, eight Cash and seven Bank Transfer. Labels can overlap. These are catalogue associations, not verified working combinations; the eight Cash records cannot automatically be treated as OXXO offers.

First, describe your customer and the purpose of the payment. A bank-transfer flow needs clear recipient details, confirmation of credit and order reconciliation. A cash payment using a reference needs an expiry rule, a confirmation event and a policy for unpaid orders. Assess payouts to recipients separately from collections.

A method or MXN label in a catalogue does not confirm that a particular country, product and payment method can be combined. Ask about availability for your legal entity, business category and expected volume. This produces a shortlist worth discussing further.

## Fees: the percentage is only part of the cost

The mean stated **percentage fee component** is **2.56% for pay-ins** and **1.20% for payouts**. The comparable samples contain 25 and 16 offers: the fee is denominated in MXN and has one unambiguous percentage. These are unweighted record averages, not market averages or complete tariffs.

Fixed charges matter particularly here. Within those samples, **17 of 25** pay-in offers have a positive fixed component of **MXN 3–18**; **12 of 16** payout offers have one of **MXN 3–8**. A zero stored field in another record does not prove that extra charges are absent. Records with another fee currency or an ambiguous percentage are excluded from the averages.

Consider two illustrative tariffs: A charges 2% + MXN 3; B charges 1% + MXN 8. On a MXN 100 payment, the costs are MXN 5 and MXN 9. On MXN 1,000, they are MXN 23 and MXN 18. They break even at MXN 500. This is a calculation example, not catalogue pricing; taxes and other charges are excluded.

Request a full-cost calculation for your average transaction: percentage, fixed charge, tax, refunds, settlement, FX and any reserve. The lowest percentage may be the more expensive choice for smaller payments.

## Settlement: payment confirmation and usable revenue

Settlement timing is populated in **26 of 29** pay-in records. T+0/D+0 appears in **6**; T+1/D+1, T+2/D+2 and T+3/D+3 each appear in **3**; T+4/D+4, T+7/D+7 and T+10/D+10 each appear in **1**. Eight records contain other terms and three do not state timing.

**T+0 on the cover is a label from some historical offers.** It does not promise same-day settlement for every business or form one combined product with the average fees. For comparison, T and D labels with the same number are grouped; the contract must define their exact meaning.

SPEI is Banco de México's system for domestic transfers in national currency. Real-time operation concerns the transfer between participating financial institutions; the gateway's release of revenue to your business requires a separate agreement. [Banco de México: SPEI](https://www.banxico.org.mx/servicios/spei_-informacion-banco-mex.html).

Ask when the clock starts: the customer's payment, the gateway's confirmation or the closing of a reconciliation batch. Agree calendar versus business days, cut-off time, minimum settlement amount, currency, reserve and release of any balance after termination. For working capital, these terms may matter more than a small percentage difference.

## SPEI and OXXO: different paths to a paid order

For SPEI, the **CEP — Comprobante Electrónico de Pago** confirms that a transfer was credited to the recipient's account using information from the receiving financial institution. Banco de México provides a service to validate its authenticity. Match a customer's screenshot against a confirmed status and your reconciliation before releasing goods. [Banco de México: MI SPEI and CEP](https://www.banxico.org.mx/servicios/mi-spei_-transferencias-ban.html).

OXXO Pay uses another journey: the customer receives a reference for an online purchase and pays cash at an OXXO store. This describes the method; it does not confirm availability in every offer in this guide. [OXXO Pay](https://www.spinnegocios.com/OXXO-Pay).

For that flow, ask how long the reference remains valid, when final confirmation arrives, how late payments are handled and how refunds work. Do not treat generated payment instructions and completed paid orders as the same success metric.

**The source provides no measured average conversion rate.** Two gateway claims lack comparable verified statistics and are excluded. In a pilot, measure method selection to completed payment, confirmation time and payout success separately, with a consistent observation window and a defined denominator.

## Terms to obtain before integration

Limits are populated in **25 of 29** pay-in and **15 of 17** payout records. They apply to different periods and scenarios, so they do not produce one universal “Mexico limit”. Compare constraints for your transaction size and turnover, rather than the catalogue's extreme values.

Ask the gateway to confirm these points in writing:

- **Payment responsibilities:** the contracting entity, receiving financial institution, beneficiary account and responsibility for reconciliation.
- **Eligibility:** your product, company jurisdiction, customer type, payment methods and required documents.
- **Full transaction cost:** each fee component, tax and charges for failed payments, refunds and settlement.
- **Limits:** transaction minimum and maximum, daily and monthly caps, and how limits may change.
- **Revenue access:** currency, schedule, reserve, bank details and return of the remaining balance.
- **Exceptions:** duplicates, wrong amounts or account details, late payments, refunds and a support contact.

If you need settlement outside Mexico, agree the cross-border arrangement and FX separately. Collecting MXN does not by itself mean the provider can send the money abroad or settle in your preferred currency.

## Licences and requirements in Mexico

Check the legal entity and its actual function. A gateway brand, API or SPEI label does not replace permission to conduct regulated activity.

Operating as an ITF requires CNBV authorisation with the agreement of the Interinstitutional Committee. The issuance, administration, redemption and transfer of electronic payment funds described in Article 22 fall within authorised IFPE activity. This does not automatically make a merchant accepting payment for its own goods an IFPE. [Fintech Law, Articles 11 and 22](https://www.diputados.gob.mx/LeyesBiblio/pdf/LRITF.pdf).

Check the financial institution's status in the [CNBV register](https://www.cnbv.gob.mx/Entidades-Autorizadas/paginas/default.aspx), and ask the provider to explain the roles and legal basis for each regulated operation. ITFs also have anti-money-laundering and counter-terrorist-financing obligations; customer documentation depends on the applicable regime and product. [CNBV: Financial Technology Institutions](https://www.gob.mx/cnbv/acciones-y-programas/instituciones-de-tecnologia-financiera).

**A payment partner's licence does not authorise the underlying business.** Betting games and draws within the relevant regime require SEGOB permission; the National Lottery exception is governed separately. A gateway cannot make prohibited games or activity without the required permission lawful. Check the permitted activity, holder, validity and conditions. [SEGOB: permitted games and illegal gambling prevention](https://www.juegosysorteos.gob.mx/es/Juegos_y_Sorteos/Juego_Ilegal_muestra), [Federal Games and Draws Law, Articles 2–4](https://www.diputados.gob.mx/LeyesBiblio/pdf_mov/Ley_Federal_de_Juegos_y_Sorteos.pdf).

## What PayStar does

PayStar helps collect and compare gateway information and provides integration technology. **PayStar is not a payment organiser:** it does not receive customer funds or settle with the merchant as part of the service described here. Those functions belong to the relevant payment provider under separate terms.

PayStar works only with lawful products that hold the licences and permissions required for their activity and territory. This is an operating principle, not a claim that every historical catalogue record has passed a legal review. Confirm eligibility, the contract and documentation before integration.
