Why the 2026 peak plan deserves a documented review

Ecommerce context

On a seasonally adjusted basis, the U.S. Census Bureau estimated first-quarter 2026 retail ecommerce sales at $326.7 billion, 9.8% above the first quarter of 2025 and equal to 16.9% of total retail sales. Use a brand's own forecast for operational planning.

Returns context

NRF and Happy Returns projected $849.9 billion in returned merchandise for 2025, equal to 15.8% of annual retail sales, and estimated that 19.3% of online sales would be returned. These are dated industry projections, not a brand forecast.

Amazon MCF context

Amazon Supply Chain Services lists U.S. MCF holiday peak fees from October 15, 2026, through January 14, 2027, plus a separately listed 3.5% fuel and logistics-related surcharge on U.S. MCF fulfillment fees.

Carrier context

FedEx publishes service- and period-specific U.S. package demand-surcharge tables for 2026. Record the current documents that apply to the actual service, destination, shipment profile and agreement.

Six operating areas

1

Demand and inbound timing

  • Forecast weekly and daily order ranges for the planned promotion calendar.
  • Put supplier departure, appointment, receiving and put-away dates on one calendar.
  • Confirm advance shipment notices, pallet labels, carton counts and late-arrival contingencies.
  • Assign decision cutoffs before marketplace, campaign and customer-delivery commitments.
2

Order profile and packaging

  • Model average and peak items per order, SKU spread, packed dimensions and weight.
  • Confirm cartonization, inserts, branded presentation and dimensional exposure.
  • Document fragility, leakage, damage-prevention and special-packaging steps.
  • Set packaging-supply quantities, reorder points and replenishment lead times.
3

Storage and inventory controls

  • Estimate pallet, case, bin and cubic-foot needs using the actual inventory plan.
  • Document lot, batch, serial, expiration, security or temperature controls where applicable.
  • Assign cycle counts, inventory exceptions, reorder points and oversell prevention.
  • Plan for dwell time, slow-moving units and post-season inventory disposition.
4

Kitting and handling requirements

  • Lock the kit bill of materials, approved substitutions and component availability.
  • Define assembly sequence, quality checks, photo proof and presentation requirements.
  • Map labeling, bundling, inserts and marketplace-preparation steps.
  • Create a rework path for missing, damaged or late components.
5

Carrier and marketplace rules

  • Use current service, zone, destination, dimensions and customer-rate-card assumptions.
  • Record applicable demand, peak, fuel, residential and marketplace charges.
  • Confirm daily pickup, cutoff, capacity, labeling, preparation and inbound rules.
  • Assign an escalation path for delayed, damaged or undeliverable orders.
6

Returns and exception management

  • Set a planning range using the brand's own channel and product history.
  • Define reason codes, inspection, disposition, restocking and inventory-update rules.
  • Assign customer-service handoffs, refund triggers and exception ownership.
  • Choose reporting that can reveal packaging, product or workflow issues.
