I am planning to change my company name on the first day of the new FY.
Should I close my existing QF account and open a new one or is there a way to keep my existing QF account, change the company name without loosing access to any of the old company data?
You can change it within QuickFile, but it will change it every where (eg your client control panel etc, even for old invoices).
If it’s the same business (same company number for example) you can change it within your settings, or you could set up a new account - the choice would be yours.
However, if it’s a different company, or you’re going from sole trader to Ltd company, then a new account would be the option to go for.
