Promotional Planning

What is promotional planning?

Promotional planning is the merchandising discipline of determining when, where, and how deeply to run promotional events across the seasonal calendar — including site-wide sales, category promotions, style-level markdowns, and channel-specific offers. In apparel, promotional planning must balance the need to accelerate sell-through on aging inventory against the imperative to protect full-price selling and brand equity.

Effective promotional planning is not simply scheduling sales events. It requires integrating inventory position data, sell-through velocity, margin targets, and competitive timing into a calendar that moves the right product at the right time without training customers to wait for discounts.

Why promotional planning matters in apparel

Apparel brands face a structural tension: seasonal product has a finite selling window, but excessive promotions erode margin and condition customers to expect discounts. The brands that manage this tension well — running promotions strategically rather than reactively — consistently outperform on both sell-through and maintained margin.

For mid-market apparel brands, promotional activity typically accounts for 20-35% of total revenue. The quality of promotional planning directly determines whether that 20-35% generates acceptable margin or destroys it. A poorly timed promotion on a style that would have sold at full price is pure margin destruction. A well-timed promotion on a style approaching markdown risk accelerates cash recovery and frees OTB for reorders.

The promotional calendar also has downstream effects on inventory planning. Every promotion changes demand patterns, which affects replenishment signals, allocation priorities, and size-level availability.

Promotional planning in practice: apparel example

A women's contemporary brand plans its spring promotional calendar in January. The team maps key promotional windows: Presidents' Day (early season acceleration), Easter (mid-season event), Memorial Day (transition clearance), and end-of-season clearance in July.

For each window, the team identifies which styles are promotional candidates based on projected sell-through curves. Styles tracking below 30% sell-through at the six-week mark enter the next promotional window. Styles tracking above 60% are excluded from promotions entirely to protect full-price margin.

The brand also staggers channel-specific promotions: DTC email promotions run two days before wholesale accounts receive markdown authorization, giving the owned channel first access to promotional demand.

Common mistakes

Running promotions on a fixed calendar regardless of inventory position. A Memorial Day sale makes sense when inventory needs acceleration. Running it when sell-through is already ahead of plan cannibalizes full-price demand for no reason.

Promoting the entire assortment instead of targeting specific styles. Site-wide percentage-off promotions discount styles that would have sold at full price. Targeted promotions on underperforming styles protect margin on the rest of the assortment.

Ignoring the training effect on customers. Brands that run promotions every two weeks teach customers to never buy at full price. The short-term sell-through gain creates a long-term margin problem that compounds every season.

Disconnecting promotional planning from buy planning. If the buy plan assumes 80% full-price sell-through but the promotional calendar implies 65%, someone is wrong. These plans must reconcile before the season starts.
