Real-time inventory in Business Central: Scan live, then post on your terms with a scanning extension
Real-time inventory in Business Central starts with the scan. Warehouse Insight is a warehouse management app for Microsoft Dynamics 365 Business Central. Resellers often sell it as an add-on. Each confirmed scan updates the warehouse document in Business Central immediately. Posting, the step that changes inventory, happens on the schedule you set.
Is each scan a live Business Central transaction?
Each confirmed scan writes straight to the document in Business Central. There is no paper and no catch-up entry at a desk later. When a picker scans an item, the line’s handled quantity updates right away. The office sees progress while the work is still happening. Anyone with access can open the document in Business Central and see what has been handled.
The scan is also checked as it happens. On a shipment, for example, Business Central validates every scan. Wrong items, quantities over the line and tracking mismatches show on the device before the worker moves on. Does scanning on a handheld update Business Central in real time? walks through this on a purchase order.
When does the item actually move to the new bin?
The item moves in Business Central when the document is posted or registered. That is standard Business Central behavior, not a scanner setting. Scanning fills in what was handled. Posting or registering commits it to inventory and bin contents. Microsoft describes this for put-aways. Microsoft’s documentation states: “When you have placed all the items in bins as instructed, choose the Register Put-away action.”
Warehouse Insight lets workers post or register from the device, so nobody walks back to a desk. Ad-hoc moves are the exception to the document flow. They need no document and post as a reclassification journal entry once the destination bin is scanned. Here is how that plays out by document:
| Document | What each scan updates | What commits the change |
|---|---|---|
| Receipt | Quantity received on the line | Posting the receipt |
| Put-away | Bin and quantity handled | Registering the put-away |
| Pick | Bin, item and quantity picked | Registering the pick |
| Movement | Take and place lines handled | Registering the movement |
| Ad-hoc move | Source bin, item and destination bin | Posted as soon as the destination bin is scanned |
| Shipment | Quantity confirmed on the line | Posting the shipment |
Can posting be held for office review?
Yes. Scanning and posting are separate decisions, and you control posting from inside Business Central. Warehouse Insight offers three posting modes:
- Auto-post on exit: The document posts or registers when the worker closes it.
- Manual posting: The worker posts from the device menu after confirming quantities.
- Supervisor-only posting: Workers scan, and a supervisor reviews and posts.
All three are set in Business Central’s device configuration, not on each handheld. The Warehouse Insight receiving page shows how supervisors use the review step. They can check a receipt before it is committed, without touching the device.
How does a scanning extension keep inventory accurate between counts?
A scanning extension keeps inventory accurate by catching errors at the bin, not at the next count. Warehouse Insight adds several checks to daily work:
- Scan to confirm: Workers scan the bin and the item, so the location is verified before a transaction posts.
- Bin content inquiry: One scan of a bin shows every item, quantity, lot and serial number Business Central holds there.
- Item inquiry: One scan of an item shows each bin it sits in and the quantity available.
- Unplanned counts: A worker who spots a short bin can count it on the spot.
With an unplanned inventory count, discrepancies show on the device before anything posts. A worker who miscounts can recount right away. Small errors get fixed before they spread into picks and orders.
Which posting mode supports real-time inventory in Business Central?
Auto-post keeps inventory closest to what happened on the floor. Every closed document commits right away, so nobody forgets to post. It suits picks, put-aways and moves, where a delay leaves bin contents out of date.
Supervisor-only posting trades a short delay for a review step. It suits receipts and shipments where the office wants to check quantities first. Many warehouses mix modes by document type. Scans stay live either way, so the office can always see what was handled.
Manual posting sits between the two. The worker decides when the document is complete and posts it from the device menu. It suits experienced teams that want control without a supervisor step. Whatever you choose, the setting lives in Business Central and applies across the device fleet.
Frequently asked questions about real-time inventory in Business Central
Does auto-post give real-time inventory in Business Central?
It gets close. Auto-post commits each document as soon as the worker closes it. Picks can also auto-register on close, so bin contents stay current.
Can offline scans still support real-time inventory in Business Central?
Warehouse Insight is built online-first, so scans normally reach Business Central immediately. When Wi-Fi drops, offline mode holds the work and sends it when the device reconnects. How Warehouse Insight works offline covers the details.
Do I need to change my posting setup to start scanning?
No. You choose a posting mode in Business Central and can change it later. Workers see the new behavior the next time they open a document.
Where are posting rules configured?
In Business Central. Posting modes, scan behavior and the fields on each screen are all set there. Nothing is managed on the device.
