If you finish making entries and there's still an amount to be allocated
To the best of your ability, you should attempt to enter accurate amounts for all your accounts so the allocation amount will be zero. If you can't find the error that led to the discrepancy, however, simply click OK and continue with the setup process. The unallocated amount will be transferred to your Historical Balancing account; this is a special account created especially for this purpose. If you locate the error later on, you can return to the Account Opening Balances window and update your entries here; the Historical Balancing account will also be updated to reflect the changes you've made.
If you're tracking stock items, we recommend that when you enter your opening balances, you avoid making an entry for your Stock asset account(s). If you've followed our recommendation, the amount to be allocated will show the value of your stock after you've made entries for all your other accounts. After you've set up individual items, their value will be added to the Stock asset account(s), and the amount to be allocated here will be reduced by an equal amount.
