Margin Without Markdown: Why Integrated Planning Is Retail’s Real Advantage

Retail’s most profitable moments happen before the product ever hits the shelf. Because by the time you’re discounting to clear space, the margin’s already gone. Today’s top retailers are shifting from reactive planning to integrated, data-driven strategies that align finance, demand, and inventory from day one.

Full-price sell-through represents more than a performance metric for retailers; it’s also a test of how well the business is aligned from plan to shelf. Discounting has become habitual and inventory risks are rising, so the ability to maintain margins without sacrificing customer satisfaction is incredibly valuable. Yet, many retail planning processes remain fragmented, reactive, and overly reliant on historical data.

Integrated planning offers a strategic alternative. By synchronizing merchandise financial planning (MFP), assortment design, store clustering, forecasting, and replenishment, retailers can build a proactive, precise, and resilient planning function. The result is better alignment across teams, more localized assortments, smarter inventory placement, and significantly higher rates of full-price sell-through.

1. Start with financial planning that informs, not just approves

Merchandise financial planning is often viewed as a budgeting exercise. But when treated strategically, MFP becomes the anchor for all downstream decisions. With the right tools, retailers can set sales and margin targets based not just on past performance but on future potential, informed by predictive analytics and real-time demand indicators.

This approach unlocks more effective open-to-buy (OTB) management and improves alignment between merchandising and finance. AI-powered MFP systems allow planners to scenario-test different investment levels, assess risk, and connect category-level decisions to SKU-level execution. In o9 client use cases, this has translated into more than 20% inventory reductions and hundreds of millions of dollars in freed-up working capital.

2. Your assortment strategy should reflect consumer reality

The shelf is where strategy and customer converge, and it’s also where many planning processes start to fall apart. With more consumers discovering products through social channels and expecting seamless omnichannel options, the need for agility in assortment planning is growing.

Retail leaders are leveraging AI to anticipate shifts in demand and align product mix accordingly. This means not just reacting to past sales trends, but proactively adjusting depth and breadth to reflect local preferences. Smart assortment planning finds the right balance: enough choice to drive engagement, but not so much that it dilutes performance or complicates supply chains.

3. Use store clustering to localize at scale

Treating all stores alike is no longer viable (if it ever was). Store clustering enables retailers to group locations by customer behavior, purchasing patterns, or channel mix. This allows for more intelligent allocation and reduces the inefficiencies of blanket inventory distribution.

The impact extends beyond stock levels. When assortments are better tailored to local demand, stores see higher conversion rates, lower markdowns, and improved margin per square foot. Store clustering also simplifies replenishment, improving supply chain agility while keeping inventory lean.

4. Forecasting fast to keep up with demand

Forecasting has evolved from a retrospective task to a real-time discipline. Machine learning models now allow retailers to incorporate dozens of variables (from weather and promotions to local events and macroeconomic trends) into highly accurate, location-specific demand forecasts.

This shift is not just technological; it’s operational. Forecasting cycles are getting shorter, and decisions are increasingly made on rolling, data-rich updates rather than rigid seasonal calendars. Retailers that embrace this model can reduce overstock and stockouts simultaneously, strengthening both margin and service levels.

5. Smarter replenishment is the final link (and the most visible)

The best planning processes still fail without responsive execution. AI-driven replenishment closes the loop by translating forecasts and performance signals into daily, store-level decisions. Rather than overcommitting to initial allocations, leading retailers use conservative first drops, then adapt dynamically based on sell-through.

This approach ensures that inventory flows to where it’s needed most, without flooding stores or over-indexing on early assumptions. It also allows teams to reallocate inventory quickly, reduce markdown exposure, and keep high-performing products in stock longer.

The payoff? Margin without the markdown

Integrated planning is not so much a system upgrade as it is a shift in mindset. When financial planning, assortment, forecasting, and fulfillment are connected through shared data and strategy, retailers can replace reactive fire drills with coordinated, data-driven action.

The outcomes speak for themselves: higher sell-through, lower inventory risk, fewer markdowns, and better use of working capital. And perhaps most importantly, a planning function that can support long-term growth, not just chase short-term targets.

As retail complexity increases, so too does the cost of fragmented planning, which is why integrated planning is how modern retailers go about turning complexity into clarity and margin risk into margin opportunity.
