Inventory integrations · Connection scope

Know what connects. Know what changes.

Start with the stores, marketplaces, and locations you actually use. Review what each connection reads, what LineNow can update, and which system owns the stock before bringing purchasing into the workflow.

01Map the stock behind the listing

Name the product and stock owner.

Choose the sellable variant, supplier item, and receiving location. Identify whether channels share the same physical stock or hold separate inventory. Keep Amazon FBA separate from stock in your own warehouse.

Choose a variant and location.
Confirm which channels share physical stock.
Keep Amazon FBA in a separate inventory pool.

02Test the events that change stock

Walk through sales and receipts.

Test a sale, cancellation, return, and partial supplier receipt in your required setup. Check which records arrive in LineNow and which stock updates reach the destination. Record the observed delay for each operation.

Start from a recorded balance.
Verify sales, returns, and receipts.
Inspect the destination result.

03Make recovery part of the evaluation

Check the exception path.

Include a missing item mapping, a disconnected account, and a repeated event in the evaluation. Agree how the team detects a failed update, reviews the last successful result, and reconciles the stock before retrying.

Test a missing mapping or disconnected account.
Identify the exception owner.
Confirm the balance before repeating an action.

Inside LineNow

Start with a purchase your team can follow.

The order activity keeps changed prices, supplier documents, and delivery context together. Then validate the separate stock handoff in the connected system at the mapped location.

Connection details

Make the integration review specific.

Bring your channel list, one SKU, and the person responsible for stock accuracy.

Walk through your setup →

Items and locations: List every store, marketplace, warehouse, and fulfillment method. Match actual identifiers, not just product names.
Direction and timing: Specify reads and writes separately. Measure update timing in your setup; no universal instant-sync promise is made here.
Access and responsibility: Confirm account permissions, item mappings, sync settings, and who reviews failures. A connector name alone does not establish your complete workflow.
Broader operations: Scope shipping, 3PL operations, accounting, and custom connectors separately. They are not implied by an inventory connection.

Practical questions

Before you connect the workflow.

Understand the setup, the handoffs, and what your team reviews along the way.

Does every integration synchronize stock in both directions?

Can I use the same stock across multiple sales channels?

Does the sample order connect to my store?

What if my channel is not listed?

See the work around the connection.
