Sub Account for parent account: Is there a limit on the number of sub accounts to an account? eg: Can you have 2000 sub accounts for a parent account like Rental income?
You don't need More Accounts. You would be using Items and Names on Transactions, so that you can report by these other cross-reference info fields. The Chart of Accounts mostly matches the tax form this entity files. Example:
I manage 147 condos on a ski hill, so Rent is a Charge Item, and there might be various Rent Charges (studio, 1bed, 4 bed, weekly rate, monthly rate, etc) and I use that on the Sales Receipt or Invoices to charge the Names. The Rent Items all link to one income account.
Example: I sell Water because I manage a water system. That means there are tier items, such as base rate, and addition levels based on over 5,000 gal and over 75,000 gal, and there are hook up fees and disconnect fees, etc. They all link to one income account for Water Service. I list as many of them that apply on the monthly invoices to each customer name.
Example: I run a law firm file and handle Trust Bank and Trust Liabilities, with One bank and One Liability, because every movement of funds is managed on a transaction for that customer name.
Example: I handle Security Deposits for Tenants = one liability account, the Service item that is linked to it, is listed on your Sales Receipt when you pay to move in. I don't manage one Subaccount by Name in the Chart of Accounts. I use the Reporting, by Name, to see all Security Deposit activities that are in just one account.
