Welcome to QuickFile! I’ll try and help you with your queries - I’ll go through them individually below.
What package are you using at the moment?
In this case, you can just adjust the opening balance to reflect the other transactions. So if you add a prepayment of £10 before the opening balance, reduce it by £10 otherwise it’ll be counted twice.
There’s an example here, although this references suppliers. The process would be similar for clients however (just reversed).
What’s the legal status of the entity? Is the club registered with anyone (like Companies House)?
Absolutely! All accounts come with a “delete all” option should you need to use it. There’s more on this here: How do I clear my account?
Yes absolutely we will be around this time next year and many years beyond. We’ve being going for over 8 years now and have ambitious plans for the future. The company was founded by my colleagues Glenn Drake (software developer) and Joseph Chaer (accountant). Both Glenn and Joe remain very active in QuickFile.
