A/P Opening Balance - QB 2008

It would be much better if you had individual amounts but I understand that sometimes you have to work with what you have. Basically, when you set up a new Supplier/Vendor, as part of setting up their name and address, you get an opportunity to specify what the outstanding balance was at a particular date. This will generate a transactionwith that date and amount. IIRC, the actual accounting entries will be to Opening Balance Equity and A/P. The bigger issue you have is how to match payments off against this new Supplier who you probably named as something like Opening Balances. Much better if you could enter bills outstanding at your start date from the individual suppliers involved

Hope that helps and good luck
