How to deal with merch overstock without writing it off

A working guide for procurement, marketing, operations and CSR teams in Mexico on how to clear excess merchandise: tax-deductible donations, internal employee programs, inter-business-unit reassignment, controlled secondary sales and responsible destruction. How to decide what gets donated, what gets sold, what gets reassigned and what gets destroyed, without eroding the brand and without leaving money in the warehouse.

Why overstock is a financial problem, not a warehouse problem

Merch overstock appears for three main reasons: a demand forecast that ran too high, an event that changed date or format and left pieces with no destination, and a supplier that no longer accepts cancellations. All three share the same symptom: boxes of tees, tumblers, notebooks or totes sitting in a warehouse in Iztapalapa, Tlalnepantla or Apodaca, paid for but with no use path, taking up space that costs money and deteriorating as the months pass.

The standard mistake is to treat overstock as a warehouse problem and leave it there. Each additional month adds to the total cost: the warehouse charges, the material degrades, inks fade, elastics expire, and pieces that cost 100 pesos to produce end up being sold for 25 or given away as forced donations at zero. The sunk cost becomes a direct loss.

The financially smart exit is to treat overstock as a balance-sheet decision within the first 90 days after the surplus is identified. There are five viable routes — tax-deductible donation, internal employee program, inter-unit reassignment, controlled secondary sale and responsible destruction — and the right combination depends on the SKU type, the material condition and the legal and brand restrictions.

In Mexico, the framework for tax-deductible donations is regulated by SAT and the Income Tax Law: donations to organizations authorized to receive deductible donations are deductible up to a cap of 7% of the fiscal year's taxable income. For corporations, that 7% is an asset that gets lost when the overstock ends up in an incinerator or a landfill.

What this guide proposes is a seven-step flow to classify the overstock within the first 30 days and make the exit decision before the sunk cost grows. It is designed for programs of 200 to 20,000 pieces, where most of the surplus actually concentrates in real operations.

What this guide is not: it is not a guide to emptying entire warehouses. For programs with five or six digits of surplus pieces, the decision includes supplier restructuring, MOQ adjustments and forecast revision; that is a different document.

The 7-step overstock exit flow

  1. Physical inventory and SKU condition. Before deciding the route, count. Separate by SKU, by condition (sealed, unopened, in original packaging, no packaging, damaged, expired) and by season. A surplus of tees with faded ink or tumblers with broken packaging does not qualify for formal donation or secondary sale; it qualifies for destruction or textile recycling.
  2. Classify the surplus into five routes. Tax-deductible donation: SKUs in original packaging, current and useful for shelters, schools, community programs or CSR events. Internal program: SKUs that employees can receive with a reported fiscal value, allocated by seniority or by event. Inter-unit reassignment: SKUs that another business unit can use in an upcoming program. Secondary sale: generic SKUs without a dominant logo, no seasonal binding, sellable to employees or to the public with controlled margin. Responsible destruction: SKUs damaged, expired or that must not reach the market under the brand.
  3. Calculate the sunk cost and the opportunity cost. The sunk cost is what you have already paid. The opportunity cost is what you will lose if you do not act within 90 days — warehouse, degradation, possible sale at zero. If the sunk cost plus 12 months of warehouse exceeds the realizable value through secondary sale, the tax-deductible donation wins. If the brand value erodes, responsible destruction wins.
  4. For donation, identify the SAT-authorized recipient. SAT maintains the directory of authorized donees. The donation is formalized with a donation contract, a delivery certificate with detailed description of the goods and a CFDI of type "Donativo" with the donee complement. Without these three documents, the deduction does not apply.
  5. For internal programs, define the fiscal value and the communication. Pieces delivered to employees are taxable income. Assign a fiscal value per piece (it can be the production cost or a lower market value), integrate it into the payroll receipt and communicate it transparently. A poorly communicated internal program reads as favoritism; a well-communicated one reads as a benefit.
  6. For secondary sale, pick the channel that protects the brand. Sale to employees with invoice, controlled outlet on site, internal second-hand platform or secondary market with minimum-price restrictions. What you avoid is the merch appearing on Mercado Libre at cost the following month; that day the brand loses twice.
  7. Document everything and close the certificate. Every movement of surplus is recorded: donation certificate, internal program settlement, secondary sale invoice, destruction certificate. Internal audit, the legal area and the fiscal area all need to see the trail. Without documentation, the next overstock starts from zero.

Common pitfalls that multiply the loss

The first pitfall is leaving the surplus in the warehouse "just in case". The warehouse costs, the material ages, and the "just in case" rarely materializes. What is not allocated within 90 days, gets destroyed within 180.

The second pitfall is donating without a deductible receipt. Donating to an organization without SAT authorization is a gesture, not a deduction. The value is lost twice: as unsold inventory and as a fiscal benefit not taken. Check the directory of authorized donees before moving the box.

The third pitfall is delivering internal merch without documenting the fiscal value. The tax authority can reclassify the delivery as retroactive taxable income and charge differences plus inflation adjustments. Always document the value and issue the receipt.

The fourth pitfall is giving away merch at events without measuring the brand impact. If giving it away makes the brand look cheap, easy to obtain, easy to discard, the effect on perception exceeds the warehouse savings. Merch given away in the wrong place costs more than merch in the warehouse.

The fifth pitfall is destroying without traceability. Destruction without a certificate, without an authorized supplier and without a waste manifest leaves the door open for the destroyed pieces to reappear in another channel. Responsible destruction is the last route, not the easiest one.

Tools, templates and references

Overstock inventory certificate: a table with SKU, quantity, condition, season, assigned route and target movement date. Raised by the operations or warehouse team within the first 14 days of identifying the surplus.

Five-route matrix: a decision table with acceptance criteria per route: minimum condition, season validity, brand value, legal restrictions, estimated fiscal value. Used to classify without improvising.

Tax-deductible donation template: the package of documents to formalize: donation contract, delivery certificate with description and value, CFDI with the donee complement and acknowledgment letter from the recipient. Reviewed with the fiscal area before issuing.

Internal program policy: a short document with the benefit rules: minimum seniority, frequency, fiscal value, payroll receipt. Communicated by HR and posted internally.

Legal and operating references: Articles 27 and 31 of the LISR, SAT directory of authorized donees, NOM-141 on textile waste recovery, contract with the destruction supplier including notarized certificate, and the brand manual with secondary-sale criteria.
