Others have responded with great answers that are prolly spot on to your question about "Tech Tools". I'll just add in accounting services for small businesses, there are a lot of software and service solutions aimed at the sole-proprietor, and not _designed to scale_ past one or two business entities. So much so that speaking with service support as one person among four business management and four operations managers, I'm often addressed as the owner ('your company'), or they want to send a 2FA text message to your phone (as if there was one mobile phone number). Their default is to assume they're dealing with an owner. To scale means to just double or triple everything--accounts, logins, which leads to the confusion about whose 2FA is really being used. ha!
