What I want is a small app that can create an account, "Mrs Miggins of 1 Acacia Avenue, London", note the amount, "£80 owed" and note the amount and date a payment is received and keep a balance. If it can be shared between 2 BB's so much the better so we won't door knock for a fee recently collected.
Don't know if you've solved your problem yet but I use Sage 50 on my BB and it works really well, especially on the go! Here's where I got mine from: Sage 50 Mobile | Access Sage 50 Accounts data from your Mobile device
. I used the free trial, which could be good for you to get an idea if its suitable?
