Ship to Amazon

If Amazon fulfils your orders (FBA), you hold stock in two places: your own warehouse and Amazon's warehouses. Stock in your own building cannot fill an Amazon-fulfilled order until it has been shipped to Amazon and checked in. That usually takes one to three weeks. An item can therefore be well stocked at home and still be days from selling out on Amazon.

The Ship to Amazon screen is your shipping schedule. For every Amazon SKU, it shows:

• when Amazon will run dry,
• the date a shipment has to leave your warehouse,
• how many units to send, and
• whether you have enough on your own shelf to send.

If you do not have enough, it gives the date you must order from your supplier.

When you see this screen

Ship to Amazon appears in the Forecast menu only when an Amazon seller account is connected to your company. If you do not sell on Amazon, the screen and its menu item do not appear. To connect an account, see Connect Amazon and Amazon settings.

Open it with Forecast ▸ Ship to Amazon (Alt+O opens the Forecast menu).

Before you start

The schedule needs three things:

1. An FBA inventory snapshot. SeroBooks reads what Amazon is holding from the inventory snapshot pulled from your seller account. Until one has been pulled, the screen says No FBA inventory snapshot has been pulled yet, so there is nothing to schedule against. Amazon ▸ Settings pulls it.
2. A transit time into Amazon. This is the number of days from a shipment leaving your warehouse to Amazon being able to sell the units. Until it is set, the screen shows How long does stock take to reach Amazon? in place of the table, with the number of SKUs waiting on it.
3. Amazon SKUs linked to your items. A SKU that is not linked to an item has no sales history or lead time to plan with. Link SKUs under Amazon ▸ Products.

To set the transit time and target cover

1. Open Amazon ▸ Settings. While no transit time is set, the Set it in Amazon ▸ Settings button on the Ship to Amazon screen takes you there.
2. Click Shipping into Amazon. The tile reads No transit time set until you have set one.
3. Fill in the window:

4. Click Save.

Changing Amazon settings requires permission to edit them. The Supplier lead time tile sits next to it in Amazon ▸ Settings. Ship to Amazon uses the supplier lead time to work out when to order goods you do not have on hand (see Reorder Levels).

Using the screen, step by step

1. Open Forecast ▸ Ship to Amazon.
2. Read the settings bar, for example Default transit into Amazon: 10 days · target cover 60 days · FBA stock as at 2026-09-24. Every date on the screen depends on these figures. The last part shows the date of the stock figures you are working from.
3. Work from the top of the list. Rows are sorted with Order from supplier first, then Ship now, Ship soon and Watch. Within each group, the shipment that should have left earliest comes first.
4. Double-click a row, or press Enter on it, to see how it was worked out (see The explanation window).
5. Build your shipment to Amazon using the SEND quantities for the rows marked Ship now and Ship soon.
6. For rows marked Order from supplier, raise a purchase order at once (see Create Purchase Orders).
7. Once Amazon's inventory has been updated, click Recalculate to work the schedule out again.

How the schedule is worked out

Demand. Only orders that Amazon fulfils are counted, less refunded units. Orders you ship yourself (merchant-fulfilled) come off your own shelf, so they are planned on Reorder Levels instead. SeroBooks forecasts each item's Amazon-fulfilled sales, day by day, in the same way as the Forecast screen: it uses the weekly and seasonal rhythm of your Amazon sales, with each item's own selling rate and trend.

Dry on. Starting from AT AMAZON, SeroBooks subtracts each day's forecast sales until nothing is left. Because this is done day by day, a sell-out that falls inside Prime Day or Black Friday is found on the right date.

Ship by. The dry-on date, less the transit time into Amazon, less three more days for picking, booking and paperwork.

Send. The forecast Amazon sales over the transit time plus the target cover days, less what Amazon already holds or is receiving, rounded up.

Order from supplier by. Worked out only when OURS is less than SEND. It is the ship-by date less the supplier lead time. The supplier lead time is the item's own Lead time (days), or the business-wide supplier lead time when the item has none. This is the same figure Reorder Levels uses, so the two screens always agree about when a purchase order has to be placed.

The explanation window

Double-click a row, or press Enter on it, to open a window named after the item. It shows:

• A sentence in plain words, for example Amazon runs dry on 2026-11-02. At 10 days in transit, the shipment has to leave by 2026-10-20. We can ship all 140 from stock on hand. When you are short, the sentence says by how many units and when the supplier order must be placed. When there is nothing to ship at all, it says so plainly and tells you to order from the supplier now, with the approximate date the stock would land.
• Sellable at Amazon, Already inbound to Amazon and, if there are any, Unsellable at Amazon.
• In our warehouse.
• Transit into Amazon and Supplier lead time.
• Ship by and, when a supplier order is needed, Order from supplier by.
• Quantity to send.

Click Close to return to the schedule.

SKUs that could not be scheduled

SeroBooks does not guess. A SKU it cannot schedule is left off the table and counted in an amber note, for example 4 SKUs could not be scheduled — usually a missing lead time or no Amazon sales history. Click Show to open Not scheduled, and why, which lists each SKU with its reason:

Permissions

Your role needs access to the Forecast module and the same access as the accounting reports. Without it, the screen shows You do not have permission for this. Ask an administrator to grant it under Users & Roles.

Tips

• Plan both legs. Reorder Levels tells you when to buy from your supplier. This screen tells you when to move stock from your warehouse into Amazon. An importer with a 90-day supplier lead time and a 10-day transit needs both dates.
• Check the FBA stock as at date in the settings bar. If it is old, the schedule is working from old stock figures.
• Track shipments once they have left under Inbound shipments. Units on their way in count in AT AMAZON, so a SKU you have just shipped drops down the list.
