Alternatives

Are there any Drupal Commerce connectors for other tax calculation vendors? Our Avalara invoices increased more than 10 fold with no change in transaction volume, making using Avalara unaffordable on the smaller business side. Avalara's response is that they have moved away from pricing plans for small businesses as their larger business market has grown and they can no longer sustain small business pricing. I am guessing the few that still use this module may be in a similar situation.
