Keeping an Online Cash Book: How to Get Control of Your Money with Grassfeld

Do you want to keep a cash book online, but without the hassle of Excel sheets, receipts, or manual entry? You're not alone. More and more people are looking for an easy way to track their income and expenses digitally, with a clear overview and meaningful insight. That’s exactly what Grassfeld was developed for. It’s a modern alternative to the traditional household ledger. In this article, we explain what keeping an online cash book actually means — and how Grassfeld handles this smartly and automatically for you.

1. What Does Keeping an Online Cash Book Involve? 📘

Keeping a cash book means recording what comes in, what you spend, and where your money goes. The difference compared to the past?

It can now be done online, automatically, and always up to date. No notebooks, no formulas, no forgotten transactions. An online cash book is therefore not just a record — it’s a tool to help you make better financial choices.

2. Grassfeld as an Online Cash Book: How It Works ⚙️

Grassfeld digitises the cash book principle and makes it practical for everyday life.

1. Link your bank account

After creating a free account, you securely link your bank account. From that moment on, all your transactions are automatically processed in your online cash book.

2. Automatically record income and expenses

Every payment and deposit appears directly in the app. You don’t need to enter anything manually, while still keeping full control.

3. Clear categories for overview

Grassfeld automatically categorises your transactions into categories such as housing, transport, groceries, and leisure. You can adjust or expand these categories so that your online cash book perfectly matches your situation.

3. Insight Instead of Loose Numbers 📊

Keeping an online cash book only becomes truly valuable when you also understand what the numbers mean. In Grassfeld, you can see:

  • Monthly overviews of income and expenses
  • Graphs showing where your money goes
  • Trends over multiple months

This quickly shows where you might be spending too much — and where there's room to save or set money aside.

4. Setting Budgets: Staying in Control During the Month 🎯

A major advantage of keeping an online cash book with Grassfeld is that you can set budgets, allowing you to make decisions based on up-to-date information. For example, set budgets of €400 per month for groceries, €100 for clothing, and €50 for going out. The app continuously shows how much room you have left. This helps you avoid finding out too late that you’ve overspent.

5. Online Cash Book with Savings Goals 💰

Where a traditional cash book mainly looks back, Grassfeld also looks ahead. In the app, you can set savings goals for major expenses such as a holiday, a car, or a home. You can see how your savings grow and how much you still need. This makes saving concrete and motivating.

6. Less Administration, More Peace of Mind 🧘♂️

The biggest advantage of keeping an online cash book is time. You no longer need to update everything daily in a notebook or Excel file. A short weekly check is often enough to maintain an overview, review budgets, and adjust where necessary. The control this gives you over your finances brings peace of mind.

7. From Online Cash Book to Financial Freedom 🚀

Keeping an online cash book is not about restricting yourself, but about being conscious with money. When you know where your money goes, you can make choices that match your goals.
