A method for preparing a financial statement for a member of a group of members participating in a community system. The method includes submitting a request to the community system for an accounting adjustment rule. The request includes an attribute of the member, an adjustment rule type, and an account of a general ledger of the member. The accounting adjustment rule is used to adjust a trial balance of the general ledger, obtaining the accounting adjustment rule from the community system based on the request, making an adjustment in the account based on the accounting adjustment rule to obtain an adjusted trial balance, validating the adjusted trial balance of the general ledger subsequent to making the adjustment, and preparing the financial statement for the member upon validating the adjusted trial balance. The accounting adjustment rule is contributed to the community system by at least one of the group of members.
