Have successfully integrated the TaxCloud service into Vm 2.0 but would like to see what the interest is if I release this commercially.
As I understand it (although info on their site is very hard to come by unless you register - never a good sign) - that the new native Avalara Tax plugin that jenkinHill mentions above is a commercial "Software as a Service"
the info I found is here - http://www.cpapracticeadvisor.com/article/10653455/2012-review-of-avalara-avatax-calc?page=2
companies with up to 700 transactions per year, the cost is $350. For higher volumes, such as up to 7,000 transactions annually, the cost is about $0.35 per transaction/lookup (about $2,400).
although have no idea how accurate this info is..
I assume TaxCloud is free - I am fully registered - the server is returning accurate tax values and address validation.
I will incl. a couple of screenshots below but at the moment I haven't bothered with Tax Exemption Certs, The TIC taxability code for the item in the cart, Notifying TaxCloud when a transaction has been authorized or Notifying TaxCloud when a transaction has been completed.
Will only continue with those if any interest is shown and then release it..
The integration is a standard installable joomla plugin - no hacks..
The taxcloud is set up as a normal Virtuemart tax rate (per bill) and the api goes off and verifies the client address and then returns the tax rate incl the shipping tax.
If the address won't verify the client is returned to the address dialog with a message.
So - if anyone interested post here please.
