many accounting firms insist that you use their preferred cloud accounting platform. we would never do that

Some firms may force you to change from your preferred cloud accounting software. We would never do that; why change something that already works well for you?
We love the flexibility of cloud accounting and the time that can be saved. Our clients use many accounting packages including Xero, SAGE, FreeAgent, Quickbooks, and we are proficient in each of them.
still prefer going old skool?
We should mention that we of course welcome clients who continue to maintain manual books and records and keep lever arch files crammed with invoices.
