Choose item types deliberately
Every item is created as a specific type, and the type governs how it behaves. Inventory items carry quantities and cost. Non-inventory items are bought or sold without tracking stock. Assemblies and kits combine components. Lot-numbered and serialized items track batches or individual units. Choosing wrongly creates rework later, because changing an item's type after transactions exist is restricted.
Settle the rules before loading: which products are tracked by lot or serial number, which are consumed on purchase, and which are bundled for sale. Write them in a short guide the item-creation team follows.
- Decide the unit of measure for buying, stocking, and selling, and define conversions.
- Use consistent naming so items can be found by people who did not create them.
- Assign a clear owner for creating and retiring items.
Locations, bins and in-transit stock
A location is any place that holds stock you want to count: a warehouse, a store, a truck, or a consignment site. Bins subdivide a location for finding and counting. Keep the structure as simple as the operation allows, since each added level means more transactions and more chances for error. Transfers between locations should go through an explicit process so stock in transit is visible instead of vanishing from both counts.
Costing methods and what they mean for margin
Inventory is valued using a costing method, commonly average cost, first-in-first-out, or standard cost. Each affects reported margin differently when prices change. Choose with your accountants based on the nature of your business and reporting requirements, and apply it consistently. Remember to include freight, duty, and handling in cost through landed-cost features if your products warrant it; otherwise margins on imported goods will look better than they are.
Implementation and integration services →Receiving, put-away and matching
Accurate inventory begins at the dock. Receipts should be recorded against purchase orders, with quantities counted and discrepancies noted, before stock is shelved and made available. Matching the receipt to the vendor bill, a process often called three-way matching, prevents paying for goods that never arrived or at prices that differ from the order. Scanners reduce mistakes and speed receiving, particularly where lot or serial numbers are captured.
Cycle counting and adjustments
Counting everything once a year finds problems too late. Cycle counting checks a rotating subset regularly, with high-value or fast-moving items counted more often. Investigate differences instead of simply adjusting them, because the cause, such as a mislabeled bin or an unrecorded return, is usually fixable. Require a reason on every adjustment and review the totals by reason each month.
Training and user enablement →Replenishment: reorder points and planning
Replenishment settings tell the system when to suggest purchase orders. Reorder points and safety stock should reflect actual demand variability and supplier lead times, and they should be reviewed regularly. Segment items by sales velocity so that fast movers receive close attention and slow movers are watched for obsolescence. The goal is a stock position that supports sales without tying up cash.
Decisions to settle before you load items
- Tracking rules. List which items are lot or serial tracked and why, since regulation or customer requirements often decide.
- Location model. Draw the physical flow of stock and match locations and bins to it.
- Costing and landed cost. Agree the method and what is included in item cost.
- Adjustment authority. Define who may adjust inventory and what review applies.
Pitfalls to avoid
- Too many locations. Every additional location multiplies transfers and counts. Add them only when they change how stock is managed.
- Allowing negative inventory by default. Selling stock that is not recorded hides receiving errors. Prevent it, or review it daily.
- Casual adjustments. Unreviewed adjustments hide process problems. Require reasons and review them.
- Stale reorder settings. Demand shifts. Revisit parameters on a schedule, not only after a stock-out.
