Sign up as a merchant, fulfillment partner or supplier. Your role decides what you see in the network.

Business Central already manages your items, stock and sales orders. But it cannot find you new merchants or free warehouse space. A one-time setup in Microsoft connects you to FSN and brings both to you.
Business Central runs your business. FSN connects you to the merchants, warehouses and suppliers who are already in the network.
Sign up as a merchant, fulfillment partner or supplier. Your role decides what you see in the network.
Enter your connection details. They are stored encrypted and never shown again.
Your products and stock are copied over once, then only the changes. FSN matches each product to the same item at your partners.
Accept a partner’s request, send your first order, and get tracking and status back automatically.
Data flows in one direction only, on purpose. Business Central stays your main system. FSN only reads from it and never changes your bookings.
| Data | Direction | When |
|---|---|---|
| Products & variants | Business Central → FSN | as soon as items change |
| Stock | Business Central → FSN | when stock movements are posted |
| Orders | Business Central → FSN | when an order is released |
| Tracking & status | Business Central → FSN | when a shipment is posted |
Each order shows why it went to that warehouse: stock, country, delivery time, cost, free space and carrier.
Your product numbers and those of your merchants, warehouses, suppliers and marketplaces all point to the same item.
Returns have their own process and status, instead of being squeezed into the original order.
Every finished shipment, open balance and yearly statement can be traced back to its order.
No. Business Central stays your main system, and FSN only reads from it. Your team keeps releasing orders and posting invoices as before; FSN picks them up from there.
Not yet. The connection only reads, on purpose: items, stock, released orders, posted invoices and posted shipments go from Business Central to FSN. Fulfillment status and tracking are shown in FSN. Writing back is already prepared and can be switched on later.
Business Central. Everything here uses the standard Business Central interface (API v2.0). Finance & Operations uses a different interface and would need its own connector.
Your IT admin sets this up in Microsoft Entra: Dynamics 365 Business Central → Application permissions → app_access (or Financials.ReadWrite.All), with admin consent. Then the app is registered once inside Business Central. In FSN you enter the tenant ID, environment, company ID and client ID. The secret is stored encrypted and never shown again.
No. FSN is an independent fulfillment network. We connect through the official, published Business Central API, like any other third-party integration.
Merchants pay a flat $49 per month — no per-order fee, no setup cost. Warehouses, fulfilment partners and suppliers use the network for free.
A partner only sees what they need to handle the order. Your customer data stays with you. FSN stores the product matches, the routing rules and a log of what happened — not a copy of your business history.
Signing up takes a few minutes and changes nothing in Business Central. Add the connection when you are ready — or talk to us first and we will look at your setup together.
