Migration to Header Level Posting (HLP) - AvaTax

  • Updated
Follow

Overview 

For existing Accounting Seed users, migrating from Billing Line Level Posting (LLP) to Header Level Posting (HLP) will require some changes in your settings. The majority of the migration steps are related to page layouts. After you complete the steps in this article, contact Customer Support to enable HLP. 

Note: If you have the Orders & Inventory module installed, in order to enable Header Level Posting (HLP), you must be using the Weighted-Average Cost methodology.

Note: For users who are installing Accounting Seed for the first time with our Iris release, HLP is the system default. Therefore, the migration process is unnecessary. 

Note: For information about using HLP, refer to the Billing Header Level Posting article. 

As part of the migration process, you should perform the following:

  1. Modify Existing in-use PDF Formats
  2. Update the Page Layout Configuration
  3. Post all Billings that have used AvaTax LLP
  4. Contact Customer Support to switch over from LLP to HLP

Post all Billings that have used AvaTax LLP

It is necessary to post all Billings that have calculated taxes using Avalara’s AvaTax functionality. This is because of the two different ways that taxes are determined under Line Level Posting (LLP) versus Header Level Posting (HLP). If the taxes are not being calculated, then this is not necessary. However, it is considered a best practice to establish a cut-off in migrating from LLP to HLP. 

Contact Customer Support to switch over from LLP to HLP

After completing the migration process, contact Customer Support to switch over from Line Level Posting (LLP) to Header Level Posting (HLP).
