How to improve your company's cash flow

Cash flow is the financial heartbeat of any business. Managing money coming in and going out is not just an accounting task—it is the core strategy that determines whether your company can survive, invest, and grow. When incoming cash fails to keep pace with outgoing expenses, your business can quickly face financial pressure, even if sales figures look healthy on paper.

Many businesses focus solely on invoicing and overlook one essential fact: invoicing is not the same as getting paid. The key to building a sustainable business lies in optimising your payment collection cycles and maintaining tight control over payment deadlines. By combining integrated digital management with full compliance with tax regulations, you can transform your company's cash flow into a genuine competitive advantage.

Key takeaways

• Real-time financial control: Using a cloud-based solution like Moloni ON allows you to monitor all incoming and outgoing transactions instantly, eliminating manual treasury errors.
• Faster customer payments: Automating payment reminders and offering digital payment methods significantly reduces your Average Collection Period (ACP).
• Certified invoicing without mistakes: Issuing tax-compliant documents and exporting the SAF-T (PT) file correctly helps you avoid penalties that can impact your cash flow.
• Tax planning: Preparing in advance for VAT, Corporate Income Tax and withholding tax deadlines prevents unexpected pressure on your available cash.
• Efficient stock management: Maintaining balanced inventory frees up working capital that would otherwise remain tied up in slow-moving products.

What is cash flow and why is it essential for your business?

Cash flow refers to the movement of money into and out of your business over a specific period. Cash inflows come from sales and services, while outflows include supplier payments, salaries, rent, taxes and day-to-day operating expenses. The key distinction is that cash flow measures available liquidity rather than accounting profit.

A business can appear highly profitable on paper yet still fail if it does not have enough cash available to meet its daily financial obligations. This often happens when customers are given much longer payment terms than those offered by suppliers. Maintaining positive cash flow ensures that your business continues operating smoothly without relying on expensive bank financing.

Beyond ensuring business continuity, healthy cash flow gives you the flexibility to negotiate better supplier terms and seize investment opportunities whenever they arise. Whether you want to expand your business, launch a new product or recruit new talent, you need complete visibility over how much cash will be available next week and next month.

How can you analyse your company's current cash flow?

Cash flow analysis should become a weekly—or at the very least monthly—habit. Start by organising every financial movement into three key categories: operating activities (your day-to-day business), investing activities (equipment or software purchases), and financing activities (loans or capital injections).

The fastest way to obtain an accurate financial snapshot is by reconciling your invoicing software with your bank statements. You should calculate two essential indicators: the Average Collection Period (ACP) and the Average Payment Period (APP). If your ACP is longer than your APP, it means you are effectively financing your customers while putting unnecessary pressure on your own liquidity.

What are the best ways to speed up customer payments?

If you want cash to reach your account faster, remove every possible barrier to payment. The first rule is simple: issue invoices immediately after delivering the product or completing the service. Every day you delay sending an invoice is another day before your customer is likely to pay.

Another highly effective strategy is expanding and modernising your payment options. Offering convenient digital payment methods directly on your invoices makes paying easier and significantly speeds up collections. With Moloni ON, these payment methods can be integrated into your digital invoices, allowing customers to pay in just a few clicks from their computer or mobile device.

Finally, establish a clear and automated collection policy. Don't hesitate to remind customers about upcoming due dates. Schedule automatic reminders before invoices become overdue and send professional follow-up notices whenever payments are delayed. You can also encourage early payments by offering small settlement discounts or applying late payment interest to discourage unnecessary delays.

How can you optimise supplier payments without damaging relationships?

Managing cash outflows requires just as much strategy as managing incoming revenue. Optimising supplier payments does not mean paying late or failing to meet agreed deadlines—it means negotiating payment terms that better match your sales cycle. If your suppliers expect immediate payment while your customers typically pay within 30 days, your cash flow will inevitably suffer.

Whenever possible, negotiate longer payment terms with trusted suppliers by demonstrating that you are a reliable business partner. Conversely, if your cash position is strong, consider offering early payment in exchange for meaningful commercial discounts. This approach reduces your operating costs while increasing your overall profit margins.

Use your payment calendar strategically by grouping supplier payments on specific dates each month—for example, on the 10th and 25th. Doing so provides greater visibility over your outgoing cash, making your bank balance far easier to manage while avoiding unexpected debits that disrupt your financial planning.

How can Moloni ON automate and transform your financial management?

Managing cash flow manually through spreadsheets is outdated and highly susceptible to costly errors. Moloni ON provides a cloud-based platform that centralises your invoicing while giving you complete visibility over your business finances. Every invoice issued through the platform immediately displays its status, allowing you to see what has been paid, what remains outstanding, and which invoices are overdue.

Automation is one of Moloni ON's greatest strengths. You can create user profiles for your team, automate recurring invoices for subscription-based customers, and schedule reminder emails for overdue accounts. All your financial data is securely stored in the cloud and remains accessible from any device, whether you're in the office or working remotely.

In addition, the platform's integration between invoicing and financial reporting significantly reduces your accountant's administrative workload. Instead of spending hours organising paperwork at the end of each month, Moloni ON automatically generates clear sales reports and simplifies data exports, allowing you to make informed business decisions based on accurate, real-time figures.

How does tax planning protect your company’s liquidity?

In Portugal, tax obligations require careful planning to ensure they do not unexpectedly drain your company's cash reserves. Value Added Tax (VAT) is the perfect example: the VAT you collect from customers does not belong to your business—it belongs to the Portuguese Tax Authority. If you spend this money on day-to-day operations, you may face serious liquidity issues when your VAT return becomes due.

The key is to set aside tax liabilities as soon as payments are received. Whenever a customer pays an invoice, allocate the corresponding VAT amount—and an estimate for Corporate Income Tax (IRC)—to a separate business savings account or reserve. Moloni ON makes this process easier by providing a clear overview of both collected VAT and deductible VAT, allowing you to anticipate your future tax obligations.

You should also keep a close eye on the Portuguese tax calendar. Meeting deadlines for submitting the SAF-T (PT) invoicing file (which must be reported by the 5th day of the month following issuance), making corporate tax prepayments and withholding tax payments helps you avoid costly penalties. Staying fully compliant with tax regulations is, in itself, one of the most effective ways to protect your company's cash flow.

How can inventory management free up working capital?

Inventory sitting on your shelves represents money that is not working for your business. If you purchase products that remain unsold for months, you are tying up cash that could otherwise be used to pay operating expenses or invest in marketing and growth. Efficient inventory management plays a crucial role in maintaining healthy cash flow.

Start by applying the Pareto Principle (ABC analysis) to your product catalogue. Identify the 20% of products responsible for generating 80% of your sales and prioritise maintaining adequate stock levels for these items. Products with slower turnover should be purchased more conservatively or managed using a Just-in-Time strategy, ordering inventory only when customer demand is confirmed.

Using your invoicing software's stock management features allows you to monitor inventory levels in real time and create minimum stock alerts. Moloni ON helps you track every inventory movement, preventing unnecessary purchases while ensuring your purchasing decisions reflect actual customer demand.

What are the most common cash management mistakes you should avoid?

One of the most common mistakes made by new business owners is mixing personal and business finances. Withdrawing money directly from your company's cash reserves for personal expenses distorts your accounting records and makes it difficult to assess your company's true financial health. Instead, establish a fixed salary or owner's draw and stick to it consistently.

Another critical mistake is being overly optimistic when forecasting future sales. Planning next month's expenses based on potential deals that have not yet been closed is a risky strategy. Always prepare your cash flow forecasts using conservative scenarios and focus on income that is already confirmed rather than expected.

Finally, operating without a working capital reserve or emergency fund leaves your business highly exposed to unexpected events. Markets can change, important customers may delay payments, or essential equipment may suddenly fail. Ideally, your company should maintain a financial reserve covering at least three to six months of fixed operating expenses, providing stability and protecting your business against unforeseen circumstances.
