Can Nonprofit import an opening trial balance?
Nonprofit data imports currently support customers, vendors and accounts only.
No. The Nonprofit data importer accepts customer lists, vendor lists and accounts without balances. Open invoices, open bills and opening-balance imports are blocked even if you have their action permissions. Contact support to plan an opening ledger with the required financial coding. Do not use the General opening files as a workaround. Read Plan your move and what can and cannot move.
