Inventory, Location, and Barcode Operations

Set up location-based stock control and use barcode flows for faster warehouse operations.

Guide overview

Use this guide when you want to operate inventory by location, reduce manual entry in the warehouse, and make barcode-based stock work easier for the team.

Define the warehouse structure

Before you start recording movements, decide how detailed your locations should be.Examples:
  • One location per warehouse
  • One location per warehouse area
  • One location per rack, shelf, or bin
Choose a structure that your team can maintain every day. If the structure is too detailed for the real operation, stock accuracy usually gets worse instead of better.

Prepare item and location master data

Barcode operations work best when the master data is stable first.
  1. Register items and keep a unique item code, SKU, or JAN code.
  2. Register locations with clear names that warehouse staff can recognize quickly.
  3. Decide which code your team will scan during daily work.
If a barcode resolves to more than one item or location, the warehouse team will slow down immediately. Stable keys matter more than clever naming.

Register opening stock and daily movements

Once the master data is ready:
  1. Create opening stock in the correct location.
  2. Use inventory transactions for daily inbound, outbound, adjustments, and transfers.
  3. Review the affected inventory record after major movements.
Recommended practice:
  • Record movements on the same day they happen.
  • Use inventory transactions for corrections instead of editing stock numbers directly whenever possible.

Use barcode or QR flows on site

Sanka supports barcode-oriented warehouse work through inventory transaction and location flows.Typical flow:
  1. Open the barcode or QR action from the inventory or location work screen.
  2. Scan the item code or barcode.
  3. Confirm the matched item or location.
  4. Enter the quantity and complete the movement.
Before wider rollout, test barcode operations with the real labels and devices used in the warehouse so you can confirm scan quality and matching rules.

Review and correct discrepancies

Even a good setup needs a review habit.
  • Check recent inventory transactions when stock looks wrong.
  • Compare physical counts with location-based inventory records.
  • Investigate repeated adjustments by item, location, or operator.
If discrepancies keep repeating, review the location structure, barcode labeling, and who is allowed to correct stock.
