SKULabs keeps a history (changelog) of what changed on your items, orders, purchase orders and transfer orders, and who changed it. Each entry spells out the old and new values, so you can see what was actually changed.
Inventory changelog: old quantity and new quantity
To see stock changes for many items at once, go to Inventory and choose Changelog (history) from the menu. To see one item, open the item and scroll to its Log panel.
Each row shows the user, location, time and type of change, plus:
Old quantity: the quantity before the change.
New quantity: the quantity after the change, so you can read what the item went from and to in one row.
Notes: extra detail about the change.
In the Changelog window, pick a date range and use Export to download the changelog as a CSV file. The export has the same values in its Old_Quantity and New_Quantity columns.
Item changes: what was edited on an item
When someone edits an item by hand or with a CSV import, the item Log lists each field that changed, for example "Cost changed from 4.5 to 5". SKULabs logs changes to:
Name, SKU, UPC, unit, fulfillment SKU and notes
Weight, weight unit and dimensions
Cost, wholesale, retail and sale prices
Active status and lag time
Serial number settings, additional barcodes and serial numbers, lot tracking and serial lot scan
A CSV import that changes nothing on an item is logged as "CSV Import but no changes detected in item fields".
Order changes: the order Activity panel
When an order is edited in SKULabs, the Activity panel on the order page lists what changed:
Items added or removed, and quantity changes ("Updated 1 to 3")
Item price, item discount, dropshipped flag and item customization changes
Address changes, with the old and new address
Order discount, tax and shipping changes
Purchase order and transfer order changes
The Activity section on a purchase order lists items added or removed, quantity and price changes, and discount, tax and shipping changes. The Activity section on a transfer order lists items added or removed and quantity changes, together with the notes entered for the update.
