Know whether Amazon needs a buy before you approve it.

Restock FBA from spare stock before you buy

An Amazon shortfall is often a placement problem, not a buying problem. Your own warehouse, a 3PL or AWD can hold units FBA needs while FBA runs short. Skuvelo checks every location before it proposes a purchase: it finds where an item is short and where it has spare, and drafts a transfer when the sales the move protects, in units times margin, are worth more than the full cost of moving them. It moves no more than the units that would otherwise be lost, so the source location is not left short in turn.

Only what is still missing after those moves becomes a draft purchase order, with the quantity, delivery date and cost in front of the buyer before anything is sent.

Stay above the 28-day low-inventory floor

Amazon charges a low-inventory-level fee on each unit shipped when an item's historical days of supply is below 28 days over both the short term (the last 30 days) and the long term (the last 90 days). Skuvelo works out both figures from your own Amazon sales and FBA stock and marks each item under 28 days, OK or exempt. Days on which FBA held none of an item and sold none are left out of the sales rate, so a stockout never shrinks the next send.

The floor is a workspace setting that defaults to 28 days. Each send is sized from your sales rate and the days a shipment takes to reach Amazon, so the item arrives back above the floor instead of dipping under it while the shipment is in transit.

Plan within your FBA storage limit

Amazon sets a monthly FBA capacity limit in cubic feet, and your Inventory Performance Index (IPI) influences it. Enter the current and next limit for each Amazon location, and Skuvelo counts what your stock at Amazon, in transit and in open drafts takes against it. When the planned sends do not fit, Skuvelo trims them, giving the space first to the units that stop an item running out and, among those, to the items that earn the most per cubic foot. Stock that does not fit stays upstream in your warehouse, a 3PL or AWD.

The same plan watches the other end: Skuvelo counts which units will be 181 days or older at Amazon on the next 15th, oldest first, so you can sell, hold or remove them before the aged-inventory surcharge lands.

Move AWD to FBA on time

With AWD as the upstream stocking point, the question for each item is how many units should leave AWD, and by when. Skuvelo divides FBA on-hand plus inbound by daily sales to get days of cover, subtracts the in-stock floor and the AWD-to-FBA transit days to get the last day a move can leave, and sizes the move so FBA lands with your target cover, in whole cases and never more than AWD holds. Moves already on the way count as inbound, so they are never counted twice.

Restock or remove: which way stock can move

Stock flows into FBA from your warehouse, a 3PL, AWD or straight from a supplier. Flowing out of FBA is different: Amazon creates a removal order, which carries a per-unit removal fee. So when FBA holds spare units that another location needs, Skuvelo labels the move a removal order rather than drafting it as a transfer, and the cost of getting them out is part of the decision.
