Have been with Squaremile for years. Always a smooth experience. Never have to worry about our payroll, accounts, etc. Regular updates and reminders for anything that needs our input, well in advance of deadlines. So there isn't a last minute scramble to get things done/submitted on time. Professional company, with lovely & helpful staff that always go the extra (square)mile.

I've been working with Square Mile Accounting for almost two years and I'm beyond happy with theirservices. The team is always friendly, responsive, and I never have to chase them on any outstanding enquiries. They look for solutions and help me to simplify any accounting aspects of my business. I can't recommend the team enough.

I've had a couple of training sessions on Xero from Harshil at Square Mile and he's been excellent. He really understands Xero and how to make it work for me.
