Inventory Assistant is a inventory taking app that can assist you in taking inventory.
Set up your SKU information, create locations that contain the SKUs you count and run your inventory count. You can also do a freeform inventory where you can enter the SKUs you are counting as you encounter them on your path thru the inventory storage areas.
If you have an inventory system that can output an xml document containing all your SKUs, you can configure an import script to quickly set up your SKU information.
Generate a PDF document when you complete your inventory or use an export script to generate an xml document that can can be uploaded to your inventory system if it supports xml imports of inventory data.
