Project Coding - Flexibility in COA coding

Summary:

What’s the best way to align project coding with the actual state where spend is incurred?

Content (please ensure you mask any confidential information):

We create projects based on approved budgets, even when the exact location of spend isn’t yet known. To proceed, we assign a default cost center—typically our HQ. Since one project can span multiple cost centers and, therefore, states, we have misaligned cost attribution in our GL resulting in indirect tax exposure. Other than creating unique projects for each cost center, how can we improve the accuracy of our project coding? Are there any attributes that can be utilized to override the default and improve recording accuracy?
