Trial balance to 3-statement forecast
If you search for “trial balance to 3-statement forecast” or “trial balance to financial forecast,” the practical question is usually: how do I turn an accounting balance into a forecast model without rebuilding every statement manually?
1) Use the trial balance as opening BS, not as the whole forecast
A TB CSV is the starting position. It should populate opening balance sheet accounts, then future transaction rows drive PL, BS, and CF movement. This keeps historical balance data separate from future assumptions.
2) Import and check mapping
- Prepare account code, account name, and balance columns, or debit and credit columns.
- Download the TB template if column names are unclear.
- Review unmapped or unusual account names before running a forecast.
- Confirm the opening BS date is the month before the forecast start.
3) Add forecast assumptions after import
After opening balances are stable, add revenue, expense, payroll, capex, loan, tax, and journal rows. Run the forecast in the browser for free, review PL BS CF linkage, then export Excel only when a deliverable is needed.
