  title: Avalara Estimate Rate Then Quote
  summary: Get a free estimated rate for an address, then create a full transaction quote there.
  description: >-
    Pairs Avalara's free rate-lookup endpoint with a full transaction
    calculation. The workflow first calls the free tax-rates-by-address endpoint
    to get an estimated combined rate for a location, then creates an
    uncommitted sales order shipping to that same address to produce an accurate
    line-level tax quote that can be compared against the estimate. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
