How to respond to a supplier that delivers late

Why late deliveries hurt more in Mexico

Late merch deliveries are not just a missed date. They cascade through production calendars, event schedules, fiscal closings and the customs paperwork that ties every imported item to a pedimento. In Mexico, a three-day delay can mean a missed Semana Santa event, a quarter-end campaign that launches a week late, or an IMMEX program whose maquiladora output does not match the projected export volume. The cost is rarely the unit price; it is the schedule cost and the reputational cost with the internal client.

The first response tends to be emotional. The right response is procedural. Most purchase orders in Mexico include penalties, but those penalties only apply if the documentation was right from the start: signed contract, accepted PO, advance payments linked to milestones, and a delivery date confirmed in writing. If any of those is missing, the legal claim is weaker than the team assumes.

This workflow assumes the supplier is willing to deliver eventually. If the supplier is insolvent, has changed ownership or is asking for a price renegotiation before resuming production, the workflow forks into a recovery procedure that is covered separately.

Common pitfalls to avoid

Do not accept partial deliveries without a written amendment. A partial drop without an amendment is interpreted as a default on the full PO, which puts you in a stronger position legally but a weaker one operationally. Pick the path on purpose.

Avoid paying the late balance until the corrected CFDI is on file. A common scam in Mexican merch supply is to deliver late, demand the balance, and then never issue the corrected invoice. Pay only against documentation that reconciles with the goods received.

Do not assume that a verbal promise of "next week" is enforceable. Verbal commitments are valid under Mexican commercial law but are extremely hard to prove without corroborating evidence. Capture every promise in a message, an email or a signed act.

Watch for the trap of compound delays. A supplier that misses by two days and then asks for a week to "make it perfect" is signalling that the production schedule is broken, not the delivery schedule. Treat the second slip as a separate event with its own escalation.

If the merch is for an IMMEX program, a late delivery can throw off the export-balance calculation that the maquiladora must file monthly. Loop in the IMMEX specialist before accepting any new date, because the customs implications are larger than the unit cost.

Do not skip the quality inspection on a late or partial shipment. The temptation is to wave it through because the program is already strained. A second dispute, this time over quality, doubles the work and pulls the supplier relationship past the point of repair. Run the full inspection, log the deviations, and use them as a separate lever in the negotiation.

Resist the urge to punish the supplier at any cost. Procurement teams that turn every late delivery into a public fight gain a reputation as difficult partners and lose access to backup suppliers. Penalties are a tool, not a moral verdict; use them proportionately, document them carefully, and only after the recovery plan is already moving.

Finally, prepare two communication scripts for the internal client: one for "delay is still recoverable" and one for "delay has eaten the event". The second script must include a concrete apology, a concrete gesture of compensation, and a realistic new plan. The internal client should hear it from you first, not from the supplier or from event-day volunteers.
