A Practical Way to Decide Between Sage and QuickBooks 

Now, let's talk about what actually matters when you're making this decision for your practice and your clients. 

Scalability & Growth Trajectory

Sage's integration options are solid but more focused. You'll find connections to major banking institutions, HMRC systems, and professional accounting tools. The selection isn't quite as broad as QuickBooks, but what's available tends to be purpose-built for professional practices.
