Profit tells you how the business did; cash tells you whether it can pay salaries next Friday. A 13-week forecast (one quarter, week by week) is the standard tool.
Running balance
=Opening + SCAN(0, Receipts - Payments, LAMBDA(acc, net, acc + net))
One formula, 13 closing balances. Then the questions that matter:
| Question | Formula | Practice data |
|---|---|---|
| Lowest balance | =MIN(balances) |
₹4,10,000 |
| First week below the ₹5 lakh buffer | =XMATCH(TRUE, balances < Buffer) |
Week 9 |
| Funding needed | =MAX(0, Buffer - MIN(balances)) |
₹90,000 |
Week 9 carries a quarterly tax payment. Knowing it in October means arranging a small overdraft or timing a collection, instead of a crisis.
