How It Works
Three steps to connect your Amazon seller account. No API keys to copy, no credentials to manage.
- Authorize via SP-API - click “Connect Amazon” and we redirect you to Amazon's authorization page. You log in with your Seller Central credentials and approve the permissions we request.
- Your FBA data syncs automatically. Inventory levels, inbound shipments, order history, and storage metrics start pulling immediately. Most accounts finish their first sync in under 20 minutes.
- FBA-specific forecasts generate within the first hour. Once we have your sales history and FBA inventory data, the forecasting engine runs with FBA lead times and constraints built in.
What We Track
Here is exactly what we pull from your FBA account and what we do with it:
| FBA Data | What We Pull | What We Do With It |
|---|---|---|
| FBA Inventory | Fulfillable, inbound-working, inbound-shipped, inbound-receiving, reserved, unfulfillable quantities | Track your true available stock, calculate days of supply using only fulfillable units |
| Inbound Shipments | Shipment status, shipped quantities, received quantities, discrepancies | Monitor shipments through every stage, flag receiving shortages early |
| Storage Fees | Monthly storage fees, long-term storage fees, fee breakdowns by ASIN | Surface storage cost per unit so you can factor it into reorder decisions |
| Inventory Health | Per-ASIN health status, aging analysis, stranded and unfulfillable inventory flags | Spot slow-moving and at-risk inventory before long-term storage fees hit |
FBA Intelligence Features
Raw FBA data is useful, but the real value is what we do with it. ReplenishRadar turns your FBA data into specific actions:
- Restock timing: we calculate when to send your next FBA shipment based on your sales velocity, current fulfillable stock, and inbound quantities already in transit
- Transfer quantity calculation: we tell you exactly how many units to send, based on your sales velocity, current stock levels, and forecasted demand
- Multi-phase lead time tracking: FBA lead times have multiple stages - warehouse prep, shipping to Amazon, check-in, and stow. We track each phase separately so your forecasts reflect the full pipeline
- Shipment tracking: monitor every inbound shipment from creation through receiving. We flag discrepancies between shipped and received quantities so you can file claims quickly
- Storage fee monitoring: see your storage costs per unit and per ASIN. We highlight overstocked ASINs that are burning through your margins in long-term storage fees
We Create and Manage Your FBA Inbound Shipments
Most FBA tools stop at telling you what to send. ReplenishRadar creates the inbound plan directly with Amazon through SP-API and carries it the rest of the way:
- Plan creation: we open, recreate, trim, or cancel the FBA inbound plan with Amazon on your behalf, no manual entry in Seller Central.
- Packing and placement: we confirm packing options and placement options, including Amazon's placement and transport fee estimates, so you see the landed cost before you commit.
- Partnered carrier transport: we generate and confirm Amazon Partnered Carrier transport for the shipment.
- Labels and tracking: we generate box and item labels and track delivery box by box as Amazon receives it.
- Warehouse floor tools: a scan-and-pack kiosk and a mobile packing view let your team pack against the plan without re-keying anything.
Plan creation happens when you (or your warehouse team) trigger it, never automatically. If a plan stalls waiting on an Amazon-required step, a background process can advance it so a shipment does not get stuck.
Sync Frequency by Plan
FBA data changes throughout the day as shipments arrive, orders ship, and inventory positions update. Your plan determines how often we refresh.
Real-time FBA inventory sync on every paid plan, Standard through Enterprise. Inventory deltas push to us the moment Amazon reports a change, so there is no polling interval to fall behind.
Every sync is incremental. We track cursors and only pull records that changed since the last run. Your account never re-downloads its entire inventory history on every cycle.
All plans also include Instant Refresh. If you need the latest FBA data right now, hit the sync button and we pull immediately.
Permissions & Security
We take a minimal-access approach to your Amazon account. Here is exactly what we request and why.
- Read access: we request roles for FBA inventory, inbound shipments, orders, and product listings, so we can track your true available stock and inbound pipeline.
- Write access, scoped to FBA inbound: we also request the roles needed to create and manage FBA inbound plans through Amazon's SP-API: packing, placement, partnered carrier transport, and shipment labels. This is the FBA Intelligence workflow above, and it is the only write scope we hold. We do not modify your product listings, change your prices, or alter account settings outside FBA inbound.
- Official SP-API authorization: ReplenishRadar is a registered SP-API developer. We follow Amazon's Acceptable Use Policy and Data Protection Policy. No screen scraping, no credential storage.
- Revoke anytime: go to Seller Central → Apps & Services → Manage Your Apps. One click removes our access completely.
- Encrypted: your authorization tokens are encrypted at rest. All data transfers happen over TLS. We never store your Amazon password.
Frequently Asked Questions
How is this different from the general Amazon integration?
The general Amazon integration page covers our full Amazon connection, including Seller Fulfilled orders and general catalog sync. This page focuses specifically on FBA features: fulfillment center inventory, inbound shipments, storage fees, and inventory health tracking.
Does ReplenishRadar track FBA inventory health?
Yes. We monitor per-ASIN health status, flag stranded and unfulfillable inventory, and track aging so you can act before long-term storage fees hit. Storage cost breakdowns by ASIN help you spot which products are burning through your margins.
Can I track inbound shipment discrepancies?
Yes. We compare shipped quantities against received quantities for every inbound shipment. When Amazon receives fewer units than you sent, we flag the discrepancy so you can file a reconciliation request or reimbursement claim promptly.
How do you handle multi-phase FBA lead times?
FBA shipments move through several stages: warehouse prep time, transit to Amazon, check-in queue, and stow time. We track historical durations for each phase and use them to calculate realistic total lead times for your restock forecasts. This is more accurate than using a single flat lead time number.
Does it work with FBA in multiple marketplaces?
Yes. If you sell on Amazon US, CA, UK, or other marketplaces, you can connect each marketplace separately. Each one syncs independently with its own data and forecasts. Your dashboard gives you a unified view across all connected marketplaces.
What about Seller Fulfilled orders?
This page covers FBA-specific features. Seller Fulfilled (FBM) orders are handled through the general Amazon integration. See the Amazon integration page for details on how we handle FBM orders, or connect both and ReplenishRadar gives you the full picture across fulfillment methods.
