Retail Planning in a Volatile World: The WSSI Approach

Weekly Sales, Stock and Intake planning is transforming how retailers manage inventory. Here's what you need to know.

WSSI (Weekly Sales, Stock and Intake) is a retail-specific planning methodology that manages inventory at a weekly level, providing a dynamic view of sales forecasts, stock positions, and planned intake across the entire product range.

Traditional monthly planning cycles are too slow for modern retail. Consumer preferences change quickly, promotional activity creates sharp demand spikes, and seasonal transitions need to be managed precisely.

sofco's WSSI solution provides retailers with a fully integrated planning environment that connects store-level sales forecasts with DC stock positions and supplier intake plans. The system automatically flags exceptions — potential stock-outs, overstock situations, or OTB breaches.

Clients using sofco's WSSI solution have consistently reported improvements in full-price sell-through, reductions in markdown depth, and lower overall inventory positions.
