Working Capital for Growing BC Businesses: Why Growth Can Drain Cash
Your sales are up. Orders are strong. You have added employees or inventory to keep pace. Your income statement may even show a healthy profit.
So why does cash feel tighter?
Rapid growth can create cash-flow pressure because the cash required to deliver new sales often leaves your business before the cash from those sales arrives. More revenue can mean more money tied up in receivables and inventory, while payroll, supplier payments, deposits and tax obligations continue coming due.
That gap is a working capital issue, and understanding it can be the difference between simply growing revenue and growing a financially healthy business.
Why Can Growth Create Cash-Flow Problems?
Revenue, profit and cash are connected, but they are not the same thing.
You can make a profitable sale today, record the revenue, and still wait 30, 60 or even 90 days to receive the money. In the meantime, you may already have paid employees, purchased materials, covered shipping costs or made supplier deposits required to complete that sale.
Working capital helps you understand your short-term financial capacity and have better cash flow management.
Working Capital = Current Assets − Current Liabilities
The BDC defines working capital this way and describes the working capital cycle, also called the cash conversion cycle, as the period required for a business to turn its investment in inventory and receivables back into cash after accounting for supplier payment timing.
As your business gets bigger, the amount required to support that cycle often gets bigger too.
A growing company may therefore need substantially more cash at $5 million in revenue than it needed at $3 million, even when its margins remain strong.
And the composition of your working capital matters. $500,000 sitting in accounts receivable is not as useful for tomorrow’s payroll as $500,000 sitting in your bank account.
Revenue tells you how much you’re selling. Working capital tells you whether you can finance the time between spending the money and getting it back. This all becomes easier when you know how to read your financial statements.
Where Growing Businesses Tie Up Their Cash
The mechanics behind growth-related cash pressure are usually not mysterious once you know where to look.
| Growth driver | What happens as you grow | Why cash can get tighter |
| Accounts receivable | More sales create more unpaid invoices | Revenue may be recorded weeks before you collect the cash |
| Inventory | More product is purchased to meet demand | Cash is invested before the inventory is sold |
| Payroll | More employees may be needed to deliver the work | Employees must be paid regardless of when customers pay |
| Deposits and prepayments | Larger orders may require commitments upfront | Cash leaves before the related revenue arrives |
| Supplier terms | Suppliers may require payment faster than customers pay you | Your business finances the timing difference |
| Taxes and remittances | More activity can mean larger tax and payroll obligations | Payment dates may arrive before related receivables are collected |
Accounts receivable: a sale is not cash until you collect it
Suppose you grow revenue substantially while customers continue paying in 45 days. Even with no deterioration in your collection process, more sales mean more dollars sitting in receivables.
If customers begin paying more slowly at the same time, the problem compounds.
That is why accounts receivable deserves more attention during periods of rapid growth. Your sales team can be succeeding while your cash position becomes progressively more strained.
Inventory: cash sitting on the shelf
Growth can require additional inventory, more product lines or higher safety stock to protect against shortages.
Some of that inventory may be entirely justified. The financial question is how long your cash remains tied up before the inventory is sold.
The BDC defines inventory turnover as cost of goods sold divided by average inventory. Slower inventory turnover generally means cash remains invested in stock for longer.
Payroll, deposits and supplier terms: timing matters
Hiring often comes before the revenue those employees will help generate. Payroll keeps moving every pay period even when customer invoices do not.
The same principle applies to supplier deposits and payment terms. If an important customer pays you in 60 days but your supplier expects payment in 30, your company has to finance that 30-day difference.
Growth magnifies these gaps because the dollar amounts become larger.
Tax timing: money in the bank may already have another purpose
Taxes add another layer.
For GST/HST registrants, CRA states that the invoice date generally determines when GST/HST has to be reported. If an invoice is included in a GST/HST return, the tax may have to be remitted even when the customer has not paid the invoice yet.
B.C. businesses that make sales subject to PST can face a similar timing issue. The Province requires businesses to report and remit PST they have charged whether or not it has actually been collected from the customer.
The specific tax treatment depends on your transactions and filing obligations. The cash-flow lesson is simpler: not every dollar showing in your bank account is necessarily available to finance growth.
A BC Example: 25% Growth and Almost $400,000 More Cash Tied Up
Consider Fraser Valley Industrial Supply Ltd., a fictional Langley-area distributor with 18 employees.
The company begins the year with $4 million in annual revenue and a 40% gross margin. On average, customers take 35 days to pay. Inventory remains in stock for approximately 45 days, while the company pays suppliers in about 40 days.
Business is strong. Revenue grows 25% to $5 million.
But larger customers negotiate longer payment arrangements, pushing average receivable days from 35 to 50. Management carries additional stock to support the higher sales volume, increasing inventory days from 45 to 55. Supplier payment timing remains at approximately 40 days.
Using rounded figures and assuming supplier purchases broadly track cost of goods sold for this simplified example, here is what happens:
Receivables increase by approximately $301,000.
Inventory increases by approximately $156,000.
Higher purchasing volume provides approximately $66,000 of additional supplier financing through accounts payable.
The result is about $392,000 in net cash invested in working capital.
And that is before considering additional employees, deposits, financing costs or tax timing.
Nothing in this example suggests the company has become unsuccessful. In fact, sales are growing rapidly.
The company has simply become more expensive to finance because of its success.
If management sees only the 25% increase in revenue, the pressure on the bank account can feel surprising. If management understands the working-capital mechanics behind the growth, it can plan for that pressure before it becomes a problem.
Four Numbers That Help You See Cash Pressure Earlier
You do not need dozens of financial ratios to get a clearer picture. Four measures can reveal a great deal about how efficiently your business is converting activity into cash.
1. Accounts receivable turnover and average collection days
Accounts Receivable Turnover = Net Credit Sales ÷ Average Accounts Receivable
This tells you how efficiently you are turning receivables into collections.
For many owners, average days receivable is even easier to interpret:
Average Days Receivable = Average Accounts Receivable ÷ Net Credit Sales × Days in Period
If your customers are supposed to pay in 30 days but your average collection period keeps moving from 35 to 42 to 50 days, your growth may be amplifying a collection problem.
There is no single ideal number for every business. What matters is the relationship between your payment terms, your industry, your historical performance and the direction of the trend.
2. Inventory turnover
Inventory Turnover = Cost of Goods Sold ÷ Average Inventory
You can convert that into days:
Days Inventory = 365 ÷ Inventory Turnover
A deteriorating trend can signal that increasingly large amounts of your cash are sitting in stock.
3. Average days payable
Average Days Payable = Average Accounts Payable ÷ Credit Purchases × Days in Period
This estimates how long, on average, you take to pay suppliers.
Longer supplier terms can help finance your operating cycle, but simply paying suppliers late is not a sound working-capital strategy. Relationships, discounts, interest and agreed terms all matter.
4. Cash conversion cycle
The cash conversion cycle brings the three timing measures together:
Cash Conversion Cycle = Days Inventory + Days Receivable − Days Payable
In plain English, it estimates how long your cash is tied up between investing in the sale and getting the money back.
A longer cash conversion cycle means cash remains tied up for longer, while reducing receivable days or inventory days—or appropriately using supplier payment terms—can shorten the cycle.
For a service business with little inventory, receivable and payable timing may matter much more than inventory days. The formula is a management tool, not a score you should optimize blindly.

How to Make Sure Growth Is Financially Healthy
Working capital management for a growing small business should begin before the growth arrives.
If you expect sales to increase by 20%, model what that does to receivables, inventory, payroll and supplier requirements. Ask how much cash has to leave before the new revenue comes back in.
Then watch the trends rather than relying only on year-end balances.
A $600,000 receivable balance tells you very little by itself. If receivables are growing twice as fast as sales, or customers are taking progressively longer to pay, that tells you something much more useful.
A rolling cash-flow forecast can help you connect expected collections with upcoming payroll, supplier, tax and debt payments. You can also look for practical ways to shorten the gap: invoice promptly, strengthen collection processes, request deposits where commercially appropriate, identify slow-moving inventory and negotiate workable supplier terms.
Finally, establish your own warning signals. Perhaps receivable days should trigger a management discussion when they rise beyond a set range. Maybe inventory days should not deteriorate beyond a particular level without an explanation. Or perhaps a line of credit that rises month after month despite profitable growth deserves investigation.
Understanding What Your Growth Is Really Costing You
When sales are increasing but cash keeps getting tighter, the answer may not be that your business is unprofitable. The issue may be how much working capital your growth requires.
Avisar Chartered Professional Accountants works with BC business owners to understand what their numbers are really saying—from profitability and cash flow to working capital, forecasting and growth planning.
When you can see where cash is being absorbed and what future growth is likely to require, you can make decisions with greater confidence rather than discovering the financial impact after the fact.
Talk to an Avisar advisor about what your growth is really requiring from your cash flow.
Frequently Asked Questions
Why can a profitable growing business run out of cash?
Profit and cash do not arrive at the same time. A growing company may pay for inventory, employees, deposits, suppliers and taxes before collecting the revenue associated with those costs. As sales rise, the dollar value of that timing gap can rise as well.
What is the cash conversion cycle?
The cash conversion cycle estimates how many days cash is tied up in your operating process. It is generally calculated as days inventory + days receivable − days payable.
What is a good cash conversion cycle for a small business?
There is no universal target that fits every business. In general, a shorter cycle means cash is tied up for less time, but appropriate levels vary substantially by industry, business model, supplier arrangements and customer terms. Comparing your own trend over time can be more useful than relying on a generic benchmark.
How much working capital does a growing business need?
There is no single percentage that applies to every company. Your requirement depends on factors such as receivable collection time, inventory needs, supplier terms, payroll, deposits, taxes, seasonality and the speed of growth. The most useful approach is to model how those factors change as revenue grows.
