What Fast does for Amazon vendors
Fast is a vendor operations platform for European Amazon retail (1P) vendors. Vendors connect their own Vendor Central account to Fast using Amazon’s authorization flow, and Fast then runs the purchase-order-to-payment cycle on their behalf: retrieving orders, acknowledging them, coordinating suppliers, confirming shipments, invoicing, and tracking what Amazon has received.
Fast is a software provider. We are not an Amazon seller or vendor. We do not resell, aggregate, or trade Amazon data, and each customer’s data is used only to operate that customer’s own account.
Inventory and Order Management
Purchase orders and acknowledgements
Every purchase order Amazon issues to the vendor is retrieved automatically and presented in one dashboard, line by line, so nothing is re-keyed from Vendor Central.
- Automatic retrieval of new and updated purchase orders with full line detail: ASIN, EAN, ordered quantity, net cost, ship window and delivery window.
- Availability check on each line against supplier stock and the vendor’s own warehouse before anything is confirmed to Amazon.
- Submission of acknowledgements with accepted, rejected and backordered quantities per line, including confirmed net cost.
- Order status tracking per PO line, showing accepted, shipped and received quantities so the vendor sees what Amazon has actually receipted.
- Alerts on lines Amazon has not confirmed and on quantity or cost mismatches between the order and the acknowledgement.
Amazon data used: Vendor Orders API — purchase orders, purchase order status, acknowledgements.
Amazon Fulfillment
Shipment confirmation and ASN
Fast turns a confirmed order into a physical pack plan, then files the advance shipment notice for it with the carton and pallet detail Amazon requires.
- Pack plan build: units assigned to cartons and cartons to pallets, with dimensions, weights and carton identifiers.
- Submission of the shipment confirmation (ASN) for both carton-level and palletized shipments, including carton and pallet counts, shipment measurements and handling codes.
- Retrieval of Amazon transport labels for the confirmed shipment.
- Re-submission of a corrected shipment confirmation when a pack plan changes after the original was filed.
- Delivery window and appointment detail held against the shipment, so warehouse and carrier work from one record.
Amazon data used: Vendor Shipments API — shipment confirmations, transport labels.
Finance and Accounting
Vendor invoicing
Invoices are generated from confirmed shipment data rather than typed by hand, so what is invoiced matches what was shipped and acknowledged.
- Invoice submission to Amazon with line detail, net cost, tax detail — including 0% reverse-charge lines for intra-EU supply — payment terms, and billing and ship-from party identification.
- Credit notes and corrections against a previously submitted invoice.
- Reconciliation of submitted invoices against the deductions and short payments recorded by the vendor, highlighting the value at stake per purchase order.
- Chargeback and dispute tracking, so finance teams can work a queue instead of a spreadsheet.
Amazon data used: Vendor Invoices API — invoice submission. Reconciliation and dispute records are built from the vendor’s own documents held in Fast.
Product Listing
Catalog and listing management
Vendors bring a catalogue of EANs; Fast matches them to Amazon’s catalogue and maintains the vendor’s own listings on the marketplaces they supply.
- Match a vendor EAN to the existing Amazon catalogue item and retrieve its ASIN, title and attributes.
- Create or update the vendor’s own listing for that item on a chosen marketplace, with cost and availability detail.
- Check listing eligibility and restrictions before submitting, and report any submission issue together with the attribute that caused it.
- Track submission status per marketplace, so vendors see which listings are live and which need attention.
- Flag EANs that do not yet exist in the Amazon catalogue so they can be handled separately.
Amazon data used: Catalog Items API, Listings Items API, Listings Restrictions — limited to the connected vendor’s own items.
Pricing
Price visibility
Commercial teams see the current Amazon price next to their own cost while they are deciding what to confirm.
- Retrieve the current Amazon price for the vendor’s own ASINs on each marketplace they supply.
- Show that price alongside supplier cost and PO net cost, so margin can be checked before an order is acknowledged.
- Highlight items where the PO net cost has moved away from previously agreed cost.
Amazon data used: Product Pricing API — price data for the vendor’s own ASINs only.
