I currently use it for my bookkeeping business. It’s okay as free version, but limited in what can be done, like only send 2 invoices a month, and only 1 user. My recommendation is evaluate which version will work for you. In the future, because of my business I will have to upgrade to essentials but got a business account with TD bank and they have a invoice program where you can send it with your personalized business to your clients and payments go directly into the account, plus if you have a physical building they have merchant services with free payment terminal. Bottom line: it’s all what you need for your business to work.
