One of the very important considerations is which integrations the POS supports. If you want to grow to multiple locations you should consider a Business Intelligence system as well as accounting software integration, or a system that does both. Ideally you want your POS data to automatically import to your BI and accounting software to minimize your administrative and accounting costs and ensure accuracy. It’s a big decision and there are a lot of systems so if you can afford to have a professional help you through it, it is worth spending the money. In software sales a lot of promises are made that are not delivered on and if you have the wrong implementation coach or don’t know which questions to ask your POS is more likely to feel like a “POS” (haha). Clover and Toast both function fine for smaller operations.
