Can your balance sheet afford your growth plan?

Every rupee of new revenue ties cash up in receivables and stock before it reaches the bank. This works out what your cycle holds today, what the plan will absorb on top, and what fixing collections first would be worth.

Your cycle today

Billed revenue, excluding GST.

What you buy or pay out to deliver. Payables and stock scale with this, not with revenue.

Receivables divided by revenue, times 30. Use actuals, not the terms you agreed.

days

Inventory divided by cost of sales, times 30. Leave at zero if you hold none.

days

Payables divided by cost of sales, times 30. Registered micro and small suppliers have a statutory limit.

days

What you are planning

Where the plan says you land. Cost of sales is assumed to hold its share.

Cash tied up in the cycle

71,46,667

That is 54 days of revenue. Growing to ₹64,00,000 a month absorbs a further 42,88,000, before a rupee is spent on the growth itself.

A moderate cycle. Growth will absorb real cash, so the plan needs to be checked against the balance sheet as well as the runway. Receivables are almost always the component worth attacking first.

Averages across the whole business, so a cycle held up by one large slow customer behaves worse than this. Statutory dues you have collected and not yet deposited are excluded on purpose: GST, TDS and the employee share of provident fund are not working capital. Nothing you type is sent anywhere or stored.

Growing companies run out of cash while profitable

A business grows 60% in a year, is profitable in every month of it, and ends with barely more cash than it started. Nobody took anything and no cost was hidden. The money went into the operating cycle, and the operating cycle scales with revenue.

This is the least intuitive thing about running a business and one of the more common ways a growing one fails. It catches services firms selling to large corporates, anyone holding stock, and every company whose customers pay in 60 days while its team is paid on the last working day of the month.

The arithmetic takes about twenty minutes by hand. This does it in a few seconds, and answers the question that matters: is the growth in your plan something the balance sheet can actually fund?

What the cycle is made of

Receivable days
How long customers take to pay after you invoice. Measured on revenue, because revenue is what you invoice. Use what actually happens, not the terms you agreed, because for most Indian B2B companies those are two different numbers by a wide margin.
Inventory days
How long stock sits before it is sold. Measured on cost of sales, because stock is carried at what you paid for it. Zero for most software and services businesses.
Payable days
How long you take to pay suppliers. Also measured on cost of sales. This is the one component working in your favour, and it has a legal ceiling for registered micro and small suppliers.

Receivables plus stock less payables is the cash the business has inside its own cycle at any moment. Divide it by revenue a day and you have the cycle in days.

Why the usual shorthand flatters you

The version of this you will find almost everywhere converts all three components into days of revenue and nets them off. It is quick, it is what most explainers do, and it is wrong in a consistent direction.

Receivables genuinely scale with revenue. Stock and payables scale with what you spend, which is a smaller number. Counting payables on revenue therefore credits you with more supplier funding than you actually have, and the error grows with your margin: the healthier the business, the more the shortcut understates the problem.

On the example below, the shorthand reports ₹48 lakh tied up when the real figure is ₹71.5 lakh. A ₹23.5 lakh difference, always in the direction that makes the plan look affordable. This calculator uses the honest version, which is why its answer may be larger than one you have seen elsewhere.

A worked example

Illustrative figures for a fictional B2B company planning to grow monthly revenue from ₹40 lakh to ₹64 lakh over a year, at a cost of sales that holds at 45% of revenue. Every number is invented.

Today, ₹40 lakh a monthPlanned, ₹64 lakh a month
Receivables at 68 days₹90.7 lakh₹1.45 crore
Payables at 32 days₹19.2 lakh₹30.7 lakh
Net cash inside the cycle₹71.5 lakh₹1.14 crore
Cycle, in days of revenue5454
Extra cash the growth absorbs₹42.9 lakh
Per ₹1 of extra monthly revenue₹1.79
Illustrative only. The cycle length does not change; the rupee amount does, because it scales with revenue.

That year produces roughly ₹65 lakh of accounting profit. Because ₹42.9 lakh of it became receivables rather than cash, about ₹22 lakh reaches the bank. A founder who built the hiring plan on the profit figure is ₹43 lakh short, and finds out somewhere around month eight.

Now change one input. Bring collection days from 68 to 45 across the year and the cycle at year end holds ₹65.3 lakh, which is ₹6 lakh less than it held at the start, on revenue 60% higher. Working capital has stopped consuming cash and started releasing it.

What the calculator shows

  • Receivables, stock and payables as rupee amounts, so you can see which one is holding the cash.
  • Net cash inside the cycle, and the cycle expressed in days of revenue.
  • What the cycle will hold at your planned revenue, with no improvement in anyone's behaviour.
  • The extra cash the growth absorbs, which is the figure to set against your runway before signing off the plan.
  • How much working capital each additional rupee of monthly revenue needs.
  • What the same plan absorbs at shorter collection days, and what the difference between the two is worth.

Where this bites hardest

  • Services firms selling to large corporates, where 60 to 90 day payment is normal and delivery cost is salaries paid monthly. The gap between paying the team and being paid is the whole problem.
  • Anyone holding physical stock, where cash leaves at purchase and returns only after a sale and then after collection. Growth here needs inventory bought for demand that has not arrived.
  • Companies selling to government or public sector buyers, where the cycle is long and largely outside your control.
  • Businesses settled by a platform or aggregator, which collects from the customer immediately and pays you on its own schedule.

And where it barely matters: subscription software billed annually in advance, and retail or food service where customers pay at the counter. Both can run a negative cycle, collecting before they pay suppliers, which means growth generates cash rather than consuming it. If that is you, this tool will tell you so in one line, and the thing to protect is the terms that make it work.

Shortening it, in order of what works

  1. 01Invoice on delivery rather than at month end. This takes days out of the cycle permanently and costs nothing.
  2. 02Bill what has been delivered and never invoiced. Most firms find a week or two of revenue sitting unbilled the first time they look.
  3. 03Fix the disputes holding invoices up. A surprising share of overdue payment is stuck on a purchase order reference or an approval nobody chased.
  4. 04Escalate on a fixed schedule rather than when someone remembers, so chasing stops being a decision each time.
  5. 05Move new contracts to advance or milestone billing. Far easier to agree at the start of a relationship than to renegotiate later.
  6. 06Order stock more often in smaller quantities, and be honest about which items are never going to sell.

Three questions before the plan is signed off

The output is only useful if it reaches the conversation where the year gets decided, which is usually a month or two before the financial year starts.

  1. 01Does the cash we hold cover both the operating loss and what the cycle will absorb? These draw on the same balance, and plans routinely account for one and forget the other.
  2. 02Can the cycle be shortened before the growth arrives rather than during it? Fixing collections at ₹40 lakh a month is considerably easier than at ₹64 lakh, when the volume of invoices has risen and nobody has time.
  3. 03Is the growth rate in this plan one the balance sheet can fund, and if not, are we willing to change the plan rather than discover the answer in month eight?

Founders who run this before the plan is signed off usually find one of two things. Either the year is affordable and can proceed with some confidence, or fixing collections first delivers most of what a funding round would have. Both answers are worth the twenty minutes, and only one of them involves talking to an investor.

What this does not do

  • It uses averages across the whole business. A cycle held up by one large slow customer behaves worse than the average suggests, because the concentration means one conversation decides most of the balance.
  • It assumes cost of sales holds its share of revenue as you grow, which is right for a stable margin and wrong if the mix is shifting.
  • It excludes statutory dues you have collected and not yet deposited. GST, TDS and the employee share of provident fund sit in your account for a few weeks and none of it is yours, so treating it as working capital is funding the business with other people's money.
  • It says nothing about the operating loss. If you are burning cash as well as funding a cycle, both draw on the same balance and both have to be covered.
  • It is a planning tool, not a forecast. For week-by-week cash, the 13-week forecast is the document that answers the question.
