How to run multiple merch events at the same time without collisions

The rule: each event is its own program

When the same operations team runs two events at the same time — say an internal convention in Cancun on March 12 to 15 and a product launch in Mexico City on March 14 — the first error is treating them as one program. They are not. Each event has its own brief, its own guest list, its own production calendar, its own packaging, its own delivery address, its own setup window, its own invoicing process, and its own owner. If you mix them into a single order the classic result is: event A receives event B's packaging, event A's sizes ship with event B's names, and the CFDI 4.0 invoice arrives with the wrong header.

Corp-Merch.MX has recommended for years to run each event as an independent program with its own order number, its own artwork file, its own calendar, and its own dedicated inventory. This does not mean double warehousing — it means stock labeled by event and by delivery date. A single pallet can hold pieces from three events provided each box is marked, each label carries the event name, and each packing list is broken down by program.

The master calendar is the first tool. It is one document that shows all events of the year with brief, approved artwork, production, warehouse, shipping and delivery dates. Corp-Merch.MX hands the master calendar to the customer at the start of the annual program and updates it weekly. Without this calendar, the collisions are discovered in production, not in planning, and the fix costs three times more than if it had been foreseen.

Plant capacity is the second front. Embroidery, screen printing, sublimation, engraving and DTG have different throughputs. A workshop that embroiders 600 pieces a day can print 2,000 a day through sublimation. When two events collide in the same week, you have to check capacity before committing to a date. Corp-Merch.MX runs three shifts for peaks, but there are products — embroidered backpacks, jackets with engraved zipper pulls, two-side logo thermos — that consume more hours per unit.

Dedicated inventory is the third front. The simplest way is to set aside a warehouse zone per event, labeled with order number and target shipping date. The more sophisticated way is to keep inventory on consignment in destination cities — Mexico City, Guadalajara, Monterrey, Querétaro — and supply each event from local stock. Corp-Merch.MX runs the second option for customers with recurring quarterly programs: consignment cuts delivery time to 24-48 hours, but it requires a repurchase commitment.

Delivery per venue or per parcel is the fourth front. For events at the company's own venue (corporate offices, host hotel, plant) delivery is on pallets or boxes with a defined route. For events at an external venue (convention center, host hotel, mall) delivery requires coordination with the logistics provider and the venue. For digital or remote events delivery is by individual parcel with prepaid tracking and delivery confirmation. Each format requires different documents and, above all, different labeling on each box.

Invoicing is the fifth front — and the least planned. Each event needs its own CFDI 4.0 with its own header (legal name, RFC, delivery address), its own VAT breakdown, its own Carta Porte 3.0 complement when there is physical shipping, and its own payment complement (REP) when payment is in installments. Corp-Merch.MX delivers one invoice per event and per purchase order, never a global invoice. This simplifies the customer's accounting and lets each event charge to its own cost center.

The owner of each event is the sixth front. When two or three events run at the same time, each needs a responsible person with authority to approve artwork, authorize quantity changes and sign off on delivery. Without a named owner, approvals stall and the calendar slips. Corp-Merch.MX asks from the quote stage that each event has an owner with name, email and phone, and that owner stays the same throughout the program.

Common errors when running multiple events at once

• Merging two events into a single purchase order. This forces production to decide priorities on the spot, without visibility, and the classic result is that the lower-urgency event ends up receiving the pieces of the priority event, or the opposite.
• Not naming an owner per event. When two events depend on the same person, approvals stall and production waits for signed artwork. Corp-Merch.MX requires a named owner before accepting the order.
• Reserving capacity with less than 15 days. The plant hits its ceiling and the promised date becomes aspirational. The event enters the waitlist and the delivery date slips. The only way out is subcontracting, which raises the unit cost.
• Confusing packaging of two similar events. When two events use the same box but different stickers, it is very easy for event A's sticker to end up on event B's box. Dedicated inventory fixes this before it separates.
• Global invoice. Mixing two events on a single CFDI complicates the cost-center charge, delays the deduction, and opens the door to SAT review. The rule: one order, one invoice.
• Not communicating quantity changes in time. If event A grows from 800 to 1,200 pieces two weeks before delivery and event B has already consumed the reserved capacity, event A ends up with a slipped date. Communication of changes must be immediate, not when convenient.
• Underestimating setup time at external venue. When the venue is a convention center with limited setup hours, arriving late means paying overtime or not having merch ready when the event starts. Corp-Merch.MX asks the customer to confirm setup hours with the venue before closing the delivery date.
