Assuming we sell into all states and that our transaction volume will reach $10 million USD, what would be the cost of calculating, collecting, and remitting sales tax to the relevant states, counties, and cities?
Assume too that we only sell one type of product (i.e. we are a specialist marketplace not a general one).
It might be worth separating into setup and recurring costs.
Any surprises in store? Or recommendations in terms of tooling or vendors?
Businesses should be businesses and handle their own taxes and legal obligations by themselves.
Additionally, if you get involved in between the seller and the buyer, YOU are now liable when it comes to taxes, as you become de-facto the seller, you have to handle returns/refunds(including the tax aspect and have to handle already paid taxes in such cases as well), audits and other legal aspects. There is simply no good reason why you should involve yourself in this whatsoever. Just facilitate the business transaction, but not the financial transaction.
