Key takeaways

  • Track every dollar moving in and out so you always know your true cash position.
  • Time payments carefully, sending vendor bills close to their due date while collecting from customers faster.
  • Forecast your cash flow regularly to spot slow stretches before they become shortfalls.
  • Build a cash reserve covering three to six months of operating expenses to absorb surprises.

So, what exactly is cash flow?

Cash flow is the movement of money in and out of your business over a set period. When more cash comes in than goes out, you have positive cash flow. When outgoing cash exceeds incoming cash, you have negative cash flow.

Proper cash flow management keeps your business afloat, and it does more than that. It also helps make your business resilient, flexible, and future-proof. Having a handle on your cash flow allows you to:

  • Forecast expenses
  • Prepare for slow months
  • Set and adjust your prices
  • Gain clarity on your spending
  • Make timely payments to your vendors
  • Know when you’re ready to scale up

What’s the difference between cash flow and profit and loss?

Cash flow tracks money moving in and out at any moment, while profit and loss (P&L) measures revenue minus expenses over a period. They are not the same, and a business can have one without the other.

Cash flow encompasses all money going in and out of the company, including loans and other monetary sources. P&L covers just the profits (revenue minus expenses) derived from business operations.

Given these differences, it’s entirely possible to have positive cash flow without being profitable, and vice versa. Let’s look at some real-life examples of how this works.

Cash flow positive vs. profitable: real-life examples of cash flow

Positive cash flow, no profit: Imagine you’re opening a pet grooming business. You get a small business loan from a local bank for $50,000. That loan is money flowing into the business, producing positive cash flow. But if you don’t book any customers in the first two months, you’re not generating revenue, so your profitability is nil.

Negative cash flow, still profitable: The reverse is also true. Say you sell second-hand cars, and most customers use a buy now, pay later option. You pay $1,000 for a car, then resell it for $1,500, with the customer paying $500 down and $1,000 due in six months. You netted a $500 profit, but your cash reserves actually went down by $500 because the rest is accounts receivable.

Negative cash flow puts business owners in a tough spot, no matter how many assets or receivables they’re owed. Planning ahead for how much cash your business should have on hand is important to its success. Profit alone isn’t enough. Positive cash flow is essential for keeping your business healthy and in a position to grow.

Types of cash flow

There’s more than one kind of cash flow, and understanding the differences can help you manage your money better.

  • Operating cash flow: money from your everyday operations, such as incoming sales and outgoing costs like payroll, rent, taxes, and vendor fees.
  • Investing cash flow: money linked to your long-term investments, like buying into a startup in your industry. The initial investment creates negative cash flow, but selling those shares later creates positive cash flow.
  • Financing cash flow: money used to fund the company, such as selling ownership shares to investors or paying dividends. This kind is especially key for startups seeking rounds of investment.

4 common cash flow issues plaguing small businesses

More than half of small businesses say uneven cash flow is one of their biggest challenges. It’s not uncommon to struggle with cash flow management, for several reasons. Here are four of the most common issues for small businesses:

Changes in the revenue stream

Fluctuations in revenue due to seasonal demand or market trends can disrupt cash flow, making it challenging to cover expenses during slower periods.

Slow-paying customers

Late or delayed payments from customers can strain your cash flow, affecting your ability to meet immediate financial obligations and invest in growth.

Operational expenses

Covering ongoing costs like rent, utilities, inventory, and payroll while maintaining enough working capital can be a delicate balancing act. It gets more complicated when you face unexpected expenses like repairs or a lost contract.

Limited access to traditional financing options

Traditional financing comes with strict requirements and lengthy approval processes. That makes it difficult for small businesses to secure the funds they need in time to protect their cash flow.

How to manage a positive cash flow

Cash flow challenges are an inevitable part of being in business, and they get harder during times of inflation, rising prices, and supply chain delays. There’s no magic formula, but a few reliable strategies can give your business the stability it needs to grow steadily. Use these tactics to keep more cash on hand and smooth out slow periods.

Make payment terms work for you

The longer you can hold onto your cash reserves, the better. Send vendor payments as close to the due date as possible, without crossing into late territory. Small changes in timing can make a big difference, letting you maximize cash flow while still keeping your financial commitments.

Consider the cost of goods sold

Adjusting your cost of goods sold (COGS) is a simple but effective way to bring more cash into your business. Buying in bulk and finding a more affordable supplier are two common methods, but feel free to get creative when it comes to reducing expenses.

Handle late payments properly

Late payments can throw off your cash flow, so make sure clients are crystal clear about when payments are due. Specify the due date at the outset and send a reminder before it arrives. Charging late fees gives clients a reason to pay on time, and offering an early payment discount incentivizes customers to pay faster, boosting your short-term cash flow.

Forecast your cash flow

Forecasting means mapping out the cash you expect to come in and go out over the weeks and months ahead. Start with your current cash on hand, add expected customer payments, and subtract known costs like payroll, rent, and vendor bills. Update it often so you can spot a slow stretch before it arrives and plan around it.

Build a cash reserve

A cash reserve is a cushion you set aside for slow seasons and surprise costs. A common guideline is to keep enough to cover three to six months of operating expenses. Building it slowly, even a little each month, gives your business room to handle late payments and unexpected repairs without scrambling.
