The question is one of the most common a growing B2B business asks — and one of the most disorienting. The P&L was correct. The accountant had done nothing wrong. The business was genuinely profitable. And every month, the bank balance fell by ₹8 Lakh. The answer was not in the P&L. It never is.
This is the accrual accounting trap in its most common form. Accrual accounting records revenue when it is earned — when a service is delivered, an invoice is raised. It records expenses when they are incurred — when a vendor delivers, when staff work. It does not record when cash actually moves.
The company's income statement showed:
| P&L Line | Monthly (Accrual Basis) | Cash Reality |
|---|---|---|
| Revenue | ₹80L | ₹25–35L actually collected |
| Staff and contractor costs | ₹38L | ₹38L paid within 15 days |
| Vendor/subcontractor costs | ₹18L | ₹18L paid within 15 days |
| Overhead (rent, software, misc) | ₹6L | ₹6L paid monthly |
| Net Profit | ₹18L (22.5%) | −₹27L to −₹37L cash outflow |
The P&L was accurate under accrual principles. The cash flow was catastrophic. Every month the business earned ₹80L in revenue and paid out ₹62L in costs — but only collected ₹25-35L in cash, because clients paid 60 to 75 days after invoice. The ₹30-35L gap was a permanent working capital drain that grew every time revenue grew.
The cash conversion cycle (CCC) is the number of days between when a business pays its costs and when it collects its revenue. A negative CCC (collect before you pay) is the gold standard — think subscription businesses, retail, or any model with advance payments. A positive CCC is the norm in B2B services, and managing it is the core of working capital discipline.
"Every day of CCC extension is working capital you are permanently financing. At ₹80L monthly revenue and 60-day payment terms, the business needs ₹1.6 Crore of working capital just to function — capital that must come from somewhere, whether that's the bank, the founder, or a credit facility."
This company's CCC: collect in 60-75 days. Pay in 15 days. CCC = 45-60 days positive — meaning the business was permanently 45-60 days short of cash on every rupee of revenue earned.
| Working Capital Driver | Before | Monthly Cash Impact |
|---|---|---|
| Customer payment terms | 60–75 days | ₹30–35L permanently tied up |
| Vendor payment terms | 15 days | ₹18L paid quickly |
| Staff payment | Last day of month | Standard |
| Net monthly cash burn | −₹8L/month despite ₹18L P&L profit | |
Most growing businesses manage cash reactively — they check the bank balance when it feels low. The 13-week rolling forecast changes this entirely. Every Sunday, the model is updated: which invoices are expected to clear this week, what payments go out, what the projected daily balance is for the next 91 days.
This visibility changes behaviour. When the forecast shows a cash shortfall in week 7, the founder has 7 weeks to act — chase a specific client, draw on the OD facility, defer a non-critical vendor payment. Without the forecast, they discover the shortfall in week 7 with no runway to respond.
Profitability is a P&L measure. Survival is a cash flow measure. The two are related but not the same, and confusing them is one of the most dangerous mistakes a growing B2B business can make. The P&L tells you whether your business model works. The cash flow forecast tells you whether it will still be operating next month.
If your business is profitable on paper but cash is always tight, the answer is in your cash conversion cycle. We can fix it in weeks, not months.
