The full seasonal buying cycle, from trade shows through clearance, with timelines and supplier responsibilities at each stage
How the full-price selling window drives markdown decisions and vendor-funded margin support
How suppliers can use the retail calendar as a proactive planning tool to hit milestones and protect margins
Success in wholesale apparel depends on understanding the retail buying calendar. Buyers, operations teams, and finance teams all work against seasonal deadlines that affect ordering, shipping, inventory performance, and margin outcomes.
This article walks through the full seasonal cycle, from market week through clearance, and explains what each stage means for suppliers operationally and financially.
Why the Buying Cycle Matters
The fashion buying calendar revolves around a core tension that retailers need to commit to inventory months before customers decide what to buy.
Because the full-price selling window is only 4 to 6 weeks, inventory turnover becomes the most important metric in the business. Products that move slowly tie up capital and increase the likelihood of markdowns later in the season. Markdowns are less an exception than a standard tool for clearing aging inventory and freeing up budget for future purchases.
That freed-up budget feeds into what's called open-to-buy, the portion of a merchandise budget kept uncommitted so buyers can react to trends and changing demand throughout the season. As consumer behavior has grown harder to predict, retailers are investing more in real-time data and AI to make faster decisions while there's still time to influence outcomes.
The whole cycle is a balancing act: commit early, sell at full price, liquidate what's left, and fund the next season's assortment.
The Full Retail Calendar at a Glance
The retail fashion year runs in overlapping cycles, typically Fall/Winter and Spring/Summer.
While timing varies by retailer, most follow the same sequence of stages, and understanding how those stages connect is often just as important as understanding the stages themselves.
Stage | Time Frame (Relative to In-Store Season) | What’s Happening | Supplier’s Responsibility |
Market Weeks & Trade Shows | 12 to 14 months before in-store | Buyers review product lines at events like MAGIC, COTERIE, or platforms like Faire which concentrate demand. | Present hero items for the season based on trend shopping and analysis; accurate line sheets; ensure strong data quality for downstream warehouse receiving and POS systems. |
Line Review and Assortment Presentation | ~9 months before in-store | Supplier creates samples for review by the retailer. | Samples get created off tech packs/spec sheet sent by the retailer (often items the retailer believes could be hero items or big buys). |
Pre-Booking & Order Cutoffs | ~6–9 months before in-store | Orders close months in advance of the actual ship date. | This is when order/assortment commitments are received. Confirm SKUs and delivery windows; negotiate upfront costs to reduce future markdown exposure; finalization of production handoff as domestic or import. |
Production | ~4–8 months before in-store | Goods are manufactured; brands manage shifting costs and risks (e.g., tariffs, sourcing volatility). | Meet production milestones; monitor lead times; stay flexible with sourcing to protect margins. |
Ship Window | ~0–3 months before in-store | Product ships to distribution centers; retailers enforce strict delivery windows. | Ship on time with accurate ASNs; negotiate payment terms (typically 30–90 days). |
In-Store Date | Week 0 (season launch) | Product hits retail floors and becomes visible to shoppers and AI discovery systems. | Ensure product data is rich, accurate, and optimized for discovery; support launch execution. Store walks are common in this time to check placement and monitor initial sales. |
Full-Price Selling | ~0–4 to 6 weeks after launch (fashion) / up to ~6 months (non-seasonal) | Core selling window at full price before markdown pressure begins. | Use real-time POS data to manage inventory and adjust in-season buying decisions. This process is highly collaborative and time-intensive for the supplier and typically involves weekly sales reporting, working with the retailer's Replenishment Manager to push product from DCs to stores, and ensuring the retailer fulfills any negotiated unit liability commitments tied to the program terms. |
Promotional & Clearance | ~6 weeks onward (fashion) / end-of-life cycle | Inventory is discounted or liquidated through planned markdowns or permanent reductions. | Manage markdown funding (vendor support); aim for controlled discounting to preserve brand integrity. |
The Faire buying calendar can serve as a useful reference for independent retailers because it highlights periods of peak buyer activity. Independent retail purchasing often occurs earlier than traditional department store buying cycles.
The chart highlights the interdependence of the fashion and apparel world, as each stage is dependent on the next. Decisions made during market week influence production timelines, shipping performance, and ultimately the amount of full-price selling time available once product reaches stores. Missed deadlines early in the process often create downstream challenges that become more difficult and expensive to correct.

The Full-Price Selling Window
Once merchandise reaches the sales floor, the full-price selling period begins. For many seasonal fashion products, this window lasts approximately four to six weeks before promotional activity increases. Because the window is relatively short, suppliers have limited time to identify trends and respond before markdown pressure begins to build. Target and Walmart, for example, tend to believe the trends seen in the first ten days of sales were predictable for the rest of the cycle. Notably, these retailers would look at print and color top sellers to find consistencies or differences by region, as well as sell through percentages and return data by color and size.
Many successful brands monitor POS data throughout the season rather than waiting for end-of-season reporting. Kate Spade used SPS Analytics to monitor sell-through performance by location during a Macy's launch, allowing the team to make inventory decisions based on store-level demand. Crocs has similarly used POS data to support assortment planning and regional demand forecasting. Together, these examples demonstrate how sales data can improve both pre-season planning and in-season inventory management.
Suppliers that review POS data regularly can identify strong-performing styles, address underperforming inventory, and make informed decisions before markdown pressure increases. Some suppliers build flexibility into their production strategy by holding a portion of inventory as undyed greige goods, allowing them to adjust colorways and prints in response to early sales trends. In many cases, small adjustments made during the first few weeks of a season can have a greater impact than larger corrective actions taken after performance has already declined.
Markdowns and Vendor-Funded Margin Support
Not all markdowns serve the same purpose, and understanding the difference can help suppliers plan more effectively. Some markdowns are built into the retail calendar from the beginning of the season, while others occur in response to inventory performance.
Planned Markdowns
Planned markdowns support scheduled promotional events such as anniversary sales, holiday promotions, and friends-and-family events. Retailers typically account for these promotions during assortment and margin planning, making them an expected part of the selling cycle.
Permanent Markdowns
Permanent markdowns occur when inventory does not sell as expected. Retailers reduce prices to clear inventory and create space for future assortments, with the timing and depth of those reductions often determined by sell-through performance.
Markdown Allowances
Markdown allowances are a common form of vendor-funded margin support. When products underperform, retailers may request financial assistance from suppliers to offset the cost of price reductions. These requests typically occur near the end of a season when inventory remains unsold and retailers are preparing for the next buying cycle.
Industry reporting from McKinsey suggests that markdown allowances continue to be a common practice across retail categories, particularly during periods of uncertain consumer demand. Suppliers should therefore treat markdown allowances as a potential cost of doing business rather than an unexpected exception.
Monitoring sell-through performance early in the season can provide additional options before markdown discussions begin. Inventory transfers, targeted promotions, and other corrective actions may help improve results while there is still time to influence the outcome. The processes for auditing, disputing, and managing markdown-related deductions deserve a dedicated discussion and will be covered in a future article.
Using the Calendar as a Planning Tool
Successful suppliers use the retail calendar as a planning framework. Rather than reacting to deadlines as they arise, they work backward from the in-store date and establish milestones throughout the season. This approach creates more time to address issues before they affect shipping performance, inventory availability, or sales results.
The following timeline provides a practical example of how suppliers can align operational activities with key retail milestones:
Ten or more weeks before the in-store date: Finalize item data and complete retailer setup requirements, including GTINs, HTS codes, and product attributes.
Approximately six weeks before the in-store date: Prepare for the ship window. Confirm routing guide compliance, labeling requirements, and ASN processes.
Immediately after launch: Review the first meaningful POS data and identify early performance trends.
Four weeks after launch: Evaluate inventory performance and determine whether inventory repositioning or additional marketing support is necessary.
The fashion buying calendar helps suppliers determine when key decisions must happen. Teams that plan against those milestones are better positioned to meet retailer requirements, maximize full-price selling opportunities, and reduce end-of-season margin pressure.
While every retailer operates on a slightly different schedule, the underlying principles remain consistent. Success depends on accurate item data, disciplined execution, and visibility into performance throughout the season.
