Working Capital Cycle Explained

‍

Profit is vanity, revenue is sanity, but cash is reality. Many businesses look profitable on paper yet struggle with financial health. You can book impressive sales but find yourself unable to pay suppliers or cover payroll. This is due to gaps between spending on stock and collecting payment from customers. That gap is called your working capital cycle.

Founders managing British SMEs regularly face this cycle. Large orders require you to purchase inventory and pay out before receiving cash. Your bank account drops after you fund new stock, while payroll and rent remain constant. Customers may not pay for weeks or months.

Learning how the working capital cycle works helps business owners anticipate challenges and manage resources. This article will explain the working capital cycle, provide steps for calculating it, and offer practical solutions for bridging gaps with reliable funding.

‍

Understanding the Working Capital Cycle

‍

Your working capital cycle measures the time between paying suppliers for materials and getting paid by your customers. Calculating it gives you insight into how long your money is tied up in operations. When the cycle is long, your cash is unavailable for use elsewhere. A short cycle frees up cash, allowing reinvestment into growth, marketing, or operations.

‍

A "good" cycle is short or negative, meaning you recover cash from customers quickly (or even before you have to pay your suppliers); a "bad" cycle is long, meaning your cash is locked up in unpaid invoices and dusty warehouse stock while your bills keep coming due.

This is important for growth as efficient cycle management ensures you have liquid cash to reinvest in new opportunities without constantly needing to dilute equity or take on expensive emergency debt.

‍

Key Formula For Working Capital Cycle

‍

The calculation for your working capital cycle uses three key timeframes:

‍

1. Inventory holding time (how many days inventory sits unsold)

2. Customer payment time (how quickly customers pay their invoices)

3. Supplier payment time (when you pay your suppliers)

‍

Working Capital Cycle Formula:

Inventory Days plus Receivable Days minus Payable Days equals Working Capital Cycle, or:

Inventory Days + Receivable Days – Payable Days = Working Capital Cycle

A positive result tells you how many days you are out of pocket between paying for stock and collecting cash. A negative cycle means you are paid before paying suppliers, which gives a clear cash flow advantage. High-volume retailers with immediate sales often work this way, while B2B businesses tend to have longer cycles.

Working Capital Cycle Formula:

Inventory Days plus Receivable Days minus Payable Days equals Working Capital Cycle, or:

‍

A positive result tells you how many days you are out of pocket between paying for stock and collecting cash. A negative cycle means you are paid before paying suppliers, which gives a clear cash flow advantage. High-volume retailers with immediate sales often work this way, while B2B businesses tend to have longer cycles.

‍

Example of Calculating Working Capital Cycle

‍

Consider "Bristol Homewares Ltd", which holds stock for 50 days, waits 40 days for customer payments, and pays suppliers after 30 days.

Calculation:

50 (Inventory days) + 40 (Receivable days) – 30 (Payable days) = 60 days.

This means the business is out of pocket for 60 days between buying materials and receiving cash from customers. Owners must fund this 60-day gap to maintain operations and take on new work.

‍

Why the Working Capital Cycle Matters For Growth

‍

Many business owners focus on the profit and loss statement or top-line sales, but the real limiter on growth is cash flow. If you sell twice as much next quarter, you need to buy double the inventory now. Unless your working capital cycle is short, you may find growth puts strain on your cash position. This is commonly called overtrading.

Understanding the cash gap in your business helps you plan for scaling and avoid unexpected cash flow problems. Measuring and tracking your cycle gives you the clarity needed to forecast accurately and fund orders with confidence.

‍

4 Key Stages of the Working Capital Cycle

‍

Breaking your cycle into clear stages reveals where improvements have the greatest impact.

‍

1. Procurement and Stock Management

‍

Your cycle begins when you purchase materials or goods. Every pound spent on unused stock reduces available cash. Buying too much results in cash being tied up in slow-moving inventory. Purchase too little and you risk stock-outs, which can result in lost business. Track inventory turnover rates and review your purchasing in line with seasonal trends.

‍

2. Production and Stock Holding

‍

Stock resting in a warehouse or under production is capital that cannot be used for new opportunities. Monitor days inventory sits unsold to spot slow-moving categories. Use regular stock audits to identify obsolete goods. Implement forecasting tools to match purchasing with demand. For SMEs using Juice Insights, data by SKU or category can highlight where small changes will drive the largest results.

‍

3. Customer Sales and Invoice Generation

‍

Making a sale does not always mean immediate cash in the bank, especially for B2B businesses. Each invoice generated starts a new countdown until payment arrives. To speed up cash flow, send invoices as soon as goods or services are delivered. Agree payment terms in advance and set clear expectations in writing.

‍

4. Collections and Payment Receipt

‍

The last stage is converting invoices into actual payments. Delayed payments can stretch your cycle and force you to fund operations longer than expected. Encourage timely payment by offering early-settlement discounts. Use automated reminders as part of your accounts receivable process. Consider credit checks for new clients to reduce the risk of late payment.

‍

Practical Steps For Optimising Your Cash Flow Cycle

‍

Optimising your working capital cycle requires action at each stage. Here are practical steps that drive genuine results.

‍

Improve Inventory Management

‍

- Review historical sales data regularly to inform more precise purchasing.

- renegotiate terms for smaller and more frequent deliveries to reduce bulk stock builds.

- discount or liquidate products that have not moved within 6 months to release cash.

- track lead times from suppliers to avoid both stockouts and overordering.

‍

Accelerate Receivables

‍

- Send electronic invoices immediately after dispatch or service delivery.

- clarify payment terms on all purchase orders.

- reward swift payment with small, pre-agreed discounts.

- use automated systems for credit control and follow up consistently.

‍

Optimise Payables

‍

- ask for longer payment windows from suppliers, ideally matching your receivables.

- only pay invoices on the due date, ensuring you retain funds as long as possible.

- develop strong supplier relationships to enable flexibility during peak trading.

‍

Dealing With Gaps Even After Optimisation

‍

Even well-managed businesses encounter working capital gaps, especially when growing fast. As turnover rises, so do cash requirements. This is why business owners search for practical guidance on working capital loans in the UK and options for more flexible business finance.

Choosing funding that tracks your operational cycle is key. Some options, such as term loans, are better for longer-term investment. Others, like revolving credit, are tailored for frequent, shifting needs. For an in-depth look at which method might suit you, see our article on Term Loan vs Revolving Credit.

‍

When to Consider Working Capital Funding

‍

- Large customer orders that require you to buy stock upfront.

- Additional staff hired before you receive customer payments.

- Entering new markets or channels with up-front costs before any return.

- Managing trading cycles with high outflows months before expected revenue.

‍

Working capital loans designed for UK SMEs can flex in line with your cash flow. Revolving credit lets you access only what you need, when you need it. This funding structure offers the control required for uneven or seasonal balances.

‍

Funding Option to Bridge The Cycle

‍

A revolving credit facility gives UK SMEs a flexible pool of funding that can be drawn upon as needed. Instead of taking one lump sum, you access funds to cover specific purchases and repay them as cash comes in from your customers. The facility then replenishes, making capital available again.

This approach matches the real cash flow patterns typical in many businesses. Interest only applies to funds drawn. You decide when to use the facility, so you never pay for capital you do not need.

For a practical breakdown of how a revolving credit facility works in detail, and the situations where it delivers best value, see Revolving Loan Facility Explained.

If you are weighing the pros and cons of revolving credit against a term loan, the guide Term Loan vs Revolving Credit compares the key differences and helps you decide which fits your requirements.
