You are not alone
Will the money last until the end of the month? If that question keeps you up at night now and then, you share it with a great many business owners. And the figures show: the worry is not exaggerated.
15 days
not even that long could half of all small businesses in the US have paid their running costs from their bank balance in 2020 if no more money had come in. Only 40 percent had more than three weeks of reserves. Five years earlier, the median business still had 27 days (JPMorgan Chase Institute).
23,900
that many companies filed for insolvency in Germany in 2025, more than at any time in over ten years. More than four out of five were micro-businesses with up to ten employees (Creditreform).
54 percent
of companies in Germany accepted longer payment terms last year (Intrum). Your customers' money arrives later, your bills still arrive on time.
More than one in four
medium-sized companies in Germany has an equity ratio below 10 percent (KfW). With so little cushion, there is not much room for surprises.
A few weeks of buffer, customers who pay later, an environment that is harder to predict than it used to be: it doesn't take a big crisis to get into trouble. A major customer who pays a month late is enough.
The good news: you don't have to guess. A cash flow plan shows you weeks in advance when things will get tight and buys you the time to act. If you know your low point, you talk to the bank before you have to, postpone spending before it is due and remind customers before the till runs dry. More figures and what they mean are in our eBook “From Plan to Payment”.
What this course is about
This crash course shows you in six short chapters how to set up your first cash flow plan: no prior knowledge, no jargon, with examples you can work through yourself. You don't need a degree or a finance department. You need your bank statements, a list of your open invoices and an hour of your time.
The course is for founders, managing directors of small and medium-sized companies and anyone who looks after the money in a business without being a finance professional. You can read it from start to finish or jump straight to the chapter you need right now. And if you only have two minutes: start with the ten rules of thumb at the end.
Along the way you will come across boxes. Each has a fixed job:
- Tip – a practical move that saves you time or trouble.
- !Watch out – a spot where many people trip up.
- €Example – a calculation to follow, with round numbers.
- Key term – a word you should know, explained in one sentence.
- AIHow AI helps – what AI can take off your hands today. One rule always applies: the AI suggests, you approve.
