I find it hard to argue with from a fairness perspective. Clearly, retail is in a much different place from when Quill was decided. My concern is more in how a mom & pop online shop operating independently complies as a practical matter, which means not only collecting the right amount for different types of items but presumably remitting and filing with a huge number of different tax jurisdictions.
We’ve been looking at tech solutions for calculation / remittance. So far only found Avalara. I’d be surprised if PayPal, Stripe, and others won’t step into this now that it’ll be fairly profitable.
Avalara and Taxamo don't list prices on their sites as far as I managed to find. Googling turns up comments saying that Avalara is expensive.
TaxJar and Taxify do list prices.
For a small business (up to 1k transactions/month) is $17/month if you pay for a year up front ($19/month on month-to-month). A transaction is either giving them an order and having them figure the tax, or looking up a rate with their API.
That will get you reports for each state, ready to file. If you want them to actually file for you, that costs more. If you have to file in all 45 states that have sales/use tax, with a monthly filing in each, it would come to $5000/year at TaxJar.
Taxify is $47/month for up to 1k transactions, and it would be $14580 to have them handle filing under the same 45 state/monthly filing assumption.
