Purchase orders for Amazon FBA sellers
Sellerside helps you buy the right quantity at the right cost: every purchase order is sized against real margin and supplier lead times.

The problem: ordering without seeing lead times and margin
Ordering too late means a stockout while goods are in transit; ordering too much locks cash into slow stock. When lead times and landed costs live in separate files, every purchase order becomes a guess.
How it works
- Reorder points come from the demand forecast built on your real sales velocity.
- Supplier lead times are taken into account to know when an order must be placed.
- Landed costs feed straight into your P&L.
- Each purchase order is sized against real contribution margin rather than a spreadsheet estimate.
What you get
- Purchase decisions linked to stock, forecast and margin in one place.
- Fewer orders placed too late or in excess.
- A clear link between what you buy and what it earns.
Limits to keep in mind
- Recommendations are only as good as the lead times and costs you record for each supplier.
- Sending a purchase order remains an action approved by the seller; Sellerside does not make supplier payments.
