What is a Site ID within Dynamics GP and how does it interact with AvaTax?

Overview

You want to know what a Site ID within Dynamics GP and how it interacts with AvaTax.

Microsoft Dynamics GP

Site ID is a location value held within GP that defines where inventory is being shipped from on a given transaction.
- This value contains address and contact information for the specific origin location.
- Within Site Maintenance you can manage which bins inventory items are transferred from when product is shipped, define what inventory management policy to follow on a per location basis, and assign specific items to specific sites.
- Examples of sites include: stores, warehouses and work centers.
The Site ID is located on the header of the Sales transaction entry window (top right).
There is also a line level site ID value. This means a user could have multiple site values on the same transaction.
Within the GP menus, Site IDs can be accessed via the path: Cards> Inventory> Site
In regards to AvaTax, the Site Id determines the origin address of a given transaction. This means that it is important to have an accurate address value attached to the site in order to calculate tax.
If there is no site ID assigned to transaction, we will default to the main company address found within Company Setup.
A blank site ID can cause the error “An address is incomplete/invalid” when calculating tax, address is required for use with Avalara AvaTax
