Most of the time, your finance department doesn’t waste time on difficult decisions, but rather on repetitive, tedious tasks. Gathering numbers, typing comments, formatting reports. This is exactly where AI comes into play in controlling – when it’s implemented correctly.
A Claude Skill is a type of package. It bundles a specific task along with instructions, a template, and calculation logic, so that Claude can complete it the same way every time – in just a few minutes. This post shows you the ten Claude Skills that take the most work off your hands in day-to-day finance and controlling tasks.
What exactly is a Claude Skill?
A skill is a collection of instructions, templates, and optional scripts. Claude determines which skill is appropriate based on the task, loads that specific skill, and applies it. Anthropic calls this “progressive disclosure.” The advantage: Claude receives only the instructions it needs at that moment, allowing it to work faster and more consistently.
There are pre-built skills available, for example on claude.ai and via the Claude API. You can also build your own skills that precisely map out your workflow. For a finance department, custom skills are the real game-changer because they understand your data sources, your formats, and your validation steps.
Why isn’t a good prompt enough in Controlling?
A prompt exists in a chat and then disappears. Its quality depends on who types it and how accurately. That’s enough for a one-time look. But it’s not enough for a process that needs to run the same way every month and be traceable.
A skill defines the process. The same data sources, the same format, the same checks. The result is repeatable, and that’s exactly what a report needs – one that someone will ultimately approve.
Which 10 Claude Skills Take the Pressure Off Your Finance Department?
The following ten skills cover the monthly cycle of a finance department, from closing the books through analysis and forecasting to reporting to the board.
1. Automatically add comments to monthly financial statements
The skill reads the actual figures for the month and writes the commentary section of the report. It explains variances in complete sentences rather than just showing numbers. What used to take two hours to write now takes just a few minutes to review.
2. Notes to the Financial Statements Based on Raw Data
Using a data export, the skill generates the finished attachment as a Word document, with the correct layout and appropriate text blocks. The numbers appear in the right places, and the wording remains consistent.
3. Income Statement and P&L Cockpit from the Cube
The skill retrieves the financial results directly from the Planning Analytics cube and builds a dashboard for management. From net revenue to EBITDA and EBIT to net income for the period, every key metric is clearly documented. It is quickly made available to senior management for ad hoc analysis.
4. Analysis of variances between planned and actual figures, with explanatory text
The skill compares planned and actual figures, identifies the largest variances, and explains them in words. It identifies the drivers, not just the difference. This way, the analysis is ready before the first request comes in.
5. Comment on the Cash Flow and Liquidity Forecast
This skill handles liquidity planning and presents the forecast in plain language. It identifies when cash flow will be tight, which positions are driving the trend, and what buffer remains. It transforms a series of numbers into a clear statement that management can use to make decisions.

6. Calculate the forecast and write it back to the cube
This skill goes beyond simply reading data. It calculates a forecast based on the actual trend and a current market factor, then writes the values – along with the rationale – back into the cube. The comment explains each number, ensuring that the planning remains transparent.
7. Prioritize open items and draft reminder messages
The skill sorts open items by due date and amount and suggests the appropriate reminder text for each case. The team makes the decision; the skill does the groundwork. This significantly reduces the workload in accounts receivable management.
8. Support budget and cost center planning
During the planning session, the skill pre-fills templates, checks for gaps, and flags unusual values. Cost center managers don’t start from scratch; instead, they revise a well-founded draft.
9. Ad-hoc Data Queries in Natural Language
Instead of building a query, you simply ask the question in plain German. The skill translates it into the appropriate Cube query and returns the number. Even if you don’t have time to design a report, you’ll still get an answer right away.
10. Prepare board and management reports
This skill compiles the monthly figures into an executive summary and creates the corresponding slides. Key messages are presented at the top, with details below, all in the correct format. Raw data is transformed into a presentation that stands up to scrutiny by the committee.
How do you implement Claude Skills in Controlling?
A skill isn’t developed through a major overhaul, but through a well-executed first use case. These five steps have proven effective.
- Choose a task that occurs frequently and is clearly defined. The monthly commentary is a good place to start.
- Clarify data access. The skill needs a fixed data source, such as the Cube, an Excel file, or a PDF.
- Build the skill properly the first time and test it with real numbers until the result is accurate without any rework.
- Set up approval processes and roles. Who is allowed to launch the skill, who reviews the results, and what gets documented?
- Roll out the skill and measure its impact. Only when it saves time should you add the next one.
- A Claude Skill bundles instructions, templates, and optional scripts into a folder that Claude loads as needed.
- Following the principle of progressive disclosure, skills only load when they match the task. This keeps the context lean.
- Pre-built skills are available, among other places, in claude.ai and via the Claude API, and custom skills can be built as well.
Glossary
Frequently Asked Questions About Claude Skills in Controlling
What sets a Claude Skill apart from a regular prompt?
A prompt is a one-time instruction in a chat. A skill is the packaged workflow behind it, with fixed data sources, a fixed format, and built-in validation steps. This ensures that it runs in a repeatable and traceable manner.
What does your finance department need to get started?
Three things are enough to get started: a clearly defined, recurring task, access to the necessary data sources, and someone to set up and test the skill properly the first time.
What about the protection of financial data?
Access is managed through controlled interfaces, and each skill can only view the data it has been authorized to access. You should consult with the appropriate department to determine the specific data protection implications for your organization.
How long does it take to build a skill?
A clearly defined skill is often developed in a matter of days, not weeks. The effort required increases with the number of data sources and the special cases it must cover.
Does a skill replace my controllers?
No. The skill handles the legwork, the wording, and the formatting. It is up to the user to evaluate the numbers and make the decision.
Why We’re the Right Partner
Skills only become useful when they’re integrated with real-world systems. That’s exactly where our work comes in. We build Claude Skills for finance and controlling and integrate them with your data environment – from IBM Planning Analytics to the BlueHive reporting platform.
We’re already putting the ten skills from this post into practice ourselves. That means you’re not getting a prototype, but a process that has proven itself in practice.
