In the current version the provider catalogue has two entries: Default - Use Sprwt Zipcode System (the standard state/zip-code tax tables) and TTR - (Colorado API). Providers are assigned per state and per kitchen, so one kitchen can use TTR for Colorado while every other state keeps the default rates. Other providers such as Avalara or TaxJar are not available yet; the design allows them to be added later as additional rows on the same card.
