You can have strong sales, profitable projects, and loyal customers and still run into cash flow issues.

In fact, many small Irish limited companies run into trouble not because they’re failing, but because they don’t have visibility.

If your cash flow feels unpredictable or you’re always one step behind on bills and taxes, here’s what’s likely going wrong and what you can do to fix it.

What is cash flow, really?

Cash flow is simply the movement of money in and out of your business. It’s different from profit. You can be profitable on paper and still run out of cash if:

• Customers pay late

• You forget to save for taxes

• You pay expenses upfront but get paid later

Good cash flow means you always have enough in the bank to cover what’s coming.

Common reasons small businesses struggle with cash flow

Here are the top causes I see every week:

• Irregular income
  You get paid in bursts, often after chasing invoices, and spend the money too quickly

• No tax forecasting
  VAT, PAYE, and Corporation Tax bills arrive without warning

• Paying yourself without a plan
  Taking out too much, too soon, and draining the business

• No real-time overview of your numbers
  You only look at your finances at year-end or not at all

Why most accountants don’t help with this

Traditional accountants focus on:

• Annual accounts

• Filing tax returns

• Telling you what happened last year

They’re reactive. They don’t give you cash flow insights during the year, and they often don’t explain what the numbers mean.

That’s where Thrive Digits is different.

Fixing cash flow starts with visibility

You don’t need to overhaul your business to improve your cash flow. You just need better visibility.

Here’s where to start:

✅ Know what’s coming in
Keep a running list of invoices due and expected payments

✅ Know what’s going out
Include fixed costs, salaries, VAT, PAYE, tax bills, loan repayments

✅ Use a cash flow tracker
Xero has built-in tools, or you can use a simple Google Sheet

✅ Review weekly
It takes 10 minutes to spot a problem before it becomes a crisis

Tracking your tax obligations is a major part of this.

Build a cash buffer

Cash flow problems feel worse when there’s no margin.

Try to build a buffer of:

• 1 month of operating costs as a starting point

• 2 to 3 months if you have long payment cycles or large tax bills due

Even €2,000–€5,000 in a reserve account can be the difference between peace of mind and panic.

Don’t rely on credit cards or loans to smooth cash flow

It might help in the short term, but it creates more pressure long term.

Instead:

• Get clear on what’s predictable

• Delay expenses where possible

• Chase overdue invoices early

Good cash flow is about managing timing, not finding more money. Poor cash flow often leads to tax shocks.

Final thoughts

Cash flow problems are common, but they’re not inevitable.

With better visibility, a small buffer, and proactive support, you can stop the cycle of stress and start planning with confidence.
