In a manual warehouse, putaway is a judgment call. An experienced worker knows where things go — mostly. A new worker guesses, or asks, or puts it somewhere convenient. Over time, inventory ends up where it ended up, and finding it later becomes its own problem.

WMSi makes putaway a system decision, not a judgment call.

Four strategies, one hybrid engine

Every product in WMSi can be assigned a putaway strategy. Four are available, and they can be combined.

FIXED assigns a product to specific bin locations. When that product arrives, WMSi directs the worker to its designated home — consolidating with existing stock if present, or to the next assigned bin if the primary is full. This suits high-velocity items and products with strict location discipline.

ABC uses velocity classification to direct inventory toward the right zone. A-class items stay close to the pick face. C-class items go to deep storage. WMSi calculates the appropriate zone and finds an available bin within it.

ZONE_RESTRICTED limits a product to specific zones regardless of other rules — useful for temperature-controlled areas, hazardous materials, or dedicated customer locations.

NEXT_AVAILABLE is exactly what it sounds like: find a valid empty or partially filled bin and direct the worker there. It's the fallback when no fixed assignment or zone preference exists, and it's smarter than it sounds — WMSi checks capacity, existing lot integrity, and allergen rules before suggesting a location.

Allergen separation enforced at the bin level

For food and beverage operations, putaway isn't just about efficiency — it's about safety. WMSi enforces configurable stacking rules that prevent allergen-containing products from being placed adjacent to or above allergen-sensitive inventory. These rules run automatically during putaway suggestion. A worker can't accidentally place a peanut-containing product above a nut-free line without the system flagging it.

What the scanner worker sees

All of this happens invisibly from the worker's perspective. They scan a product, scan a location, and WMSi either confirms the placement or redirects them. The strategy engine runs in the background. The worker follows directions.

For VARs with customers who've struggled with inventory scattered across a warehouse — or with compliance requirements around product separation — the putaway strategy system is one of the more immediately demonstrable capabilities WMSi brings to an Acumatica implementation.
