Why Project Billing Event AR invoice lacks attribute for tax calculation in Avalara?

Summary:

When a billing event happens in Project, It populates details of billing event in the invoice line description when the AR invoice is created by Autoinvoice.
This is causing issue when Avalara evaluates tax on these invoice as Billing event as it doesn't contain any inventory item, or tax category or product category, resulting into wrong calculation of Tax.
Avalara is integrated with Oracle for us as a standard package to estimate and evaluate tax on AR invoice.
