Sage isn't as easy to use as QuickBooks. Our researchers found Sage won't limit clients or invoices across any of its plans, but it doesn't offer as much software flexibility and its customer support isn't as good as what is offered by other software like QuickBooks. Sage allows businesses to stay on top of their income and expenditures and unlike a lot of accounting software, Sage only has two tiers. This makes it easy to decide if you want to invest or not.
