Ask HN: To techdriven founders/startups – pains and fears in accounting/tax?

Calculating how much sales tax to collect (when building internal ecommerce payment processing) and figuring out how to report "transient" cashflow (for instance payouts to vendors who sell on a platform) on taxes while not counting it as income.

Figuring out how to file taxes for a small team incorperated as an LLC is also a bit daunting, especially when all team members are in different states working remote.
