ChatGPT training for entrepreneurs is becoming increasingly important in 2026. This complete ChatGPT guide teaches you the essential AI techniques to turn ChatGPT into a powerful business assistant that saves time and delivers better results. Whether you are a small business owner in Belgium or a marketer looking to use ChatGPT – this masterclass offers practical ChatGPT tips for immediately applicable results.
For entrepreneurs, this means: learning to work with AI tools like ChatGPT is no longer a luxury, but a necessity.
“In a sense, ChatGPT is already more powerful than any human who has ever lived. Hundreds of millions of people rely on it daily for increasingly important tasks.”
Why most entrepreneurs misuse ChatGPT
"Writing a blog post about marketing" yields generic content. Successful ChatGPT users in Belgium and the Netherlands think differently: they provide context, specify their target audience, and request concrete output. The distinction between weak and effective ChatGPT prompts determines whether you spend 10 minutes or 2 hours to achieve the same result.
As writing better prompts already explained: the quality of your ChatGPT input determines the quality of your output. But how do you create better AI prompts for your Dutch business?
The CLEAR System for Better Prompts
Forget complicated frameworks. For daily use, CLEAR suffices:
C - Context: Provide background about your situation
L - Length: Specify how long/short you want the output to be
E - Expertise: What role should ChatGPT adopt?
A - Action: What exactly needs to happen?
R - Result: What does success look like?
This system builds upon the RACE model for ChatGPT prompts, but is simpler to apply for daily business tasks.
Example of a weak prompt:
"Write an email for customers"
Example of a strong prompt:
"You are a customer service expert. Write a friendly but professional email (150 words) to customers who are receiving their order late. Explain that the delay is due to high volume, offer a solution, and maintain goodwill. The tone should be understanding without being overly apologetic."
Five ChatGPT Techniques You Can Apply Today
1. The Expert Panel
Have ChatGPT provide multiple perspectives:
"Provide advice on our new pricing strategy from three roles:
A marketer focused on customer value
A CFO who looks at margins
A sales manager who needs to close deals
Compare their advice and provide a balanced recommendation."
2. The Step-by-Step Plan Method
For complex projects:
"Create a step-by-step plan to double our Instagram followers in 6 months. For each step, provide specific actions, a timeline, and expected results."
3. The Improvement Cycle
Have ChatGPT check itself:
"First, write a product description for our new software. Then, evaluate it for persuasiveness and clarity. Rewrite it into a version that performs better."
4. The Persona Approach
For targeted content:
"Write as Mark, 38 years old, owner of a webshop with 50 products. He wants to sell more but has limited budget and time. Write from his frustrations about complex marketing tools."
5. The format template
For consistent output:
"Create a weekly newsletter with this structure:
Opening line (personal)
Main tip (1 paragraph)
Tool recommendation (short review)
Inspiration quote
Call to action"
Custom GPTs: your personal AI assistants
Custom GPTs are ChatGPT versions that you train for specific tasks. Think of a copywriter who knows your tone of voice, or a data analyst who understands your reports.
“Artificial intelligence will transform every industry, just as electricity did 100 years ago.”
Three GPTs every entrepreneur should have:
1. Content Creator GPT
Upload your best content, brand guide, and target audience info. This GPT writes blogs, social posts, and emails in your style.
2. Strategy Advisor GPT
Add your business plan, market analyses, and previous strategies. Ideal for brainstorming new initiatives.
3. Customer Service GPT
Train with frequently asked questions, product info, and your communication style. Perfect for drafting answers to customer inquiries.
How to build an effective Custom GPT:
Start specific: "Email marketing expert for B2B software" works better than "Marketing expert"
Upload relevant documents: Tone-of-voice guide, successful campaigns, customer feedback
Test with real scenarios: Try different prompts and refine the instructions
Update regularly: Add new insights and examples
Practical applications by business area
Marketing and content
Social media planning: "Plan 30 LinkedIn posts for this month around the theme 'productivity for entrepreneurs'"
Blog ideas: "Generate 10 blog topics that help our target audience with [specific problem]"
Email sequences: "Write a 5-part welcome series for new newsletter subscribers"

Sales and customer contact
Personalize quotes: "Rewrite this standard quote for a tech startup that wants to grow quickly"
Follow-up emails: "Write a friendly reminder email for clients who haven't responded to the quote"
Handle objections: "Provide 3 ways to respond to 'you are too expensive'"
These techniques combine excellently with traditional performance marketing strategies for a complete sales approach.
Operations and efficiency
Document procedures: "Convert this phone call into a step-by-step guide"
Summarize meetings: "Create a brief summary with action points from these minutes"
Training materials: "Develop a checklist for new customer service employees"
Projects: retaining context
ChatGPT Projects save your conversations and documents by topic. This way, you build knowledge that ChatGPT remembers:
By client: All communication, briefs, and output in one project
By campaign: From planning to evaluation
By quarter: Strategic planning and progress
Pro tip:
Upload at the start of each project:
Your brand guide or tone-of-voice document
Information about your target audience
Examples of previous work that performed well
Common mistakes and how to avoid them
Error 1: Overly vague prompts
Bad: "Help me with marketing"
Better: "Provide 5 concrete actions to generate more leads for my web design agency"
Error 2: Not providing context
Bad: "Write a newsletter"
Better: "Write a monthly newsletter for small restaurant owners about trends in the hospitality industry"
Mistake 3: Not checking output
Always read what ChatGPT produces. Correct errors, add personal details, and adapt it to your situation.
Mistake 4: No iteration
If the initial output isn't perfect, provide feedback: "Make the tone more professional" or "Add more concrete examples"
Advanced tips for better results
Upload files strategically
ChatGPT can analyze PDFs, Word documents, and spreadsheets. Upload your best content as a reference for new projects.
Combine with other tools
Notion: For organizing ChatGPT output
Canva: For visualizing ChatGPT concepts
Google Sheets: For data analysis by ChatGPT
For e-commerce, you can also combine ChatGPT with Shopify AI apps and automations for a complete digital workflow.
Build a prompt library
Save successful prompts in a document. This way, you don't have to rethink how to ask for something every time.
The future: AI as a strategic partner
Companies that strategically deploy ChatGPT gain a competitive advantage:
Speed: Developing ideas within minutes
Consistency: Always the same quality output
Scalability: More content without extra staff
Creativity: New perspectives and ideas
“The relationship between humans and AI is not a competition, but a partnership. Collaboration between humans and AI is key to unlocking the full potential of this technology.”
