One location can be short while another holds more stock than it can use. Buying again may be unnecessary, but moving everything that looks “spare” can create the next shortage at the source. Multi-Location Stock Transfer Optimizer calculates from available stock after reservations, damage and safety stock, then checks demand dates, pack sizes, route lead time, capacity and expiry.

The outcome in one sentence: you see which whole packs to move on which route, by when they arrive, what they cost and how many units stay short — calculated from your own records, with every step shown.

The baseline shows what happens with no transfer. The plan then selects integer packs and routes without moving more than the source can release. A lot is not used when it will expire before arrival plus the required shelf-life. Proposed stock is not treated as moved: inventory changes only when a user approves, dispatches and receives the transfer.

When shortage and expiry costs are supplied, the tool can compare the monetary outcome with transport and handling cost. When those values are unknown, it does not manufacture “savings”; it reports units short, units at expiry risk and cash transfer cost separately. The result also states whether the optimiser proved that no better plan exists or merely found a feasible plan before its time limit.

Worked example from the demo: Store A has 40 units on hand, 5 reserved, 0 damaged and a safety stock of 15, so 20 units can be released. Store B needs 10 units. The item moves in packs of 5, so the plan sends 2 packs. The route has a fixed cost of 50 and 2 per unit: 50 + 2 × 10 = 70. If the safety stock at A rises to 35, nothing can be released, the earlier proposal is flagged as infeasible and the new plan moves nothing — and says why.

What it does not do: it does not order from suppliers, book carriers, connect to a bank or point-of-sale system, or route stock through a third location. It does not give legal, tax or insurance advice. Lead times, costs, capacities and shelf-life rules are the values you enter.

Open the demo first: three fictional scenarios (three shops with a seasonal imbalance, expiry-sensitive dairy stock, and pack, capacity and date conflicts) show every screen with real results, “How calculated” panels and sample reports. A one-time purchase gives you the full online tool and the offline program package; an active PRO subscription gives you the full online tool while it is active, without the offline package. Both let you download your own reports and backups.
