The question is who keeps the books
If you or a member of your staff genuinely maintains ledgers, journals and reconciliations, an accounting product is the right tool and switching would remove it. If your CA does that work and the accounting screens in your current software are set up once and never opened, you are carrying machinery you do not run. That is the honest test, and it decides the answer more reliably than any feature list.
What a shop-first product changes
The screens follow a working day rather than an accounting structure. Billing is one screen. The outstanding list tells you who to call. Stock tells you what to order. The day's figures are on the dashboard rather than in a report you have to run. Nothing asks you to classify a transaction into a ledger, because a sale is a sale. The accounting comes out at the other end for whoever needs it.
What you give up, plainly
Double-entry journals, a chart of accounts, cost centres, bank feeds and the statutory reporting depth of an accounting suite. Your CA prepares the books from sales, purchase, stock valuation and GST summaries instead. For most shops that is a fair trade and often a cheaper one; for a business with an internal finance function it is not.
Moving off cloud accounting
Cloud accounting exports well, so contacts, items and outstanding balances come across cleanly. Two things need a decision before you start. First, ask your CA which date to take closing balances at and whether they want a final set of reports out of the old system — doing that once is much easier than reconstructing it later. Second, decide what happens to the old subscription: keep it running read-only for a quarter if there is any chance you need a report from it, then close it. On this side the setup is your shop details, items with real units, parties with balances, and the bill format. Thirty minutes on a call, and you bill in it. There is no chart of accounts to design, which is usually the part people expect to take longest.
