# Design the transaction workflow

This section describes some best practices when designing your document workflow. Before beginning, consider the following questions:

* What kind of marketplace are you designing? Will you collect and pay tax everywhere or only in selective jurisdictions?

* When is it appropriate to call AvaTax for tax calculation?

* When will you record (commit) a transaction?
