Hello Eversir, 

Thanks for commenting on this thread, 

We have taken your feedback on board and we will pass it on to our developers. 

As simplestart doesn't have the feature of bills. 

You could do this workaround if you are not wanting to upgrade to the next package that does cover bills. 

The workaround is you would need to create a deposit and in the account column of the 'add funds to this deposit' section select the same expense account that was originally used in the bill/expense.
