What Claude Is Good At

Before getting started, it helps to know when to use Claude versus other tools:

Claude is particularly strong for:

Reading and summarising long documents (it handles up to 200,000 words in a single conversation)
Writing formal proposals, reports, and professional communications
Following multi-step, detailed instructions consistently
Analysis and reasoning tasks
Safe, careful outputs (less likely to produce harmful or inaccurate content)

Use ChatGPT or Gemini instead for:

Real-time web search (ChatGPT Browse, Gemini Search)
Image generation (ChatGPT with DALL-E)
Deep Google Workspace integration (Gemini)

Step 3: Set Up a Project for Your Business

The Projects feature (available on Pro) is one of Claude’s most powerful features for business use. It lets you give Claude persistent context about your business so you do not need to re-explain it in every conversation.

To create a Project:

Click **Projects** in the left sidebar
Click **New Project**
Name it (e.g., “My Business – [Your Business Name]”)
Click **Project Instructions** and write a description of your business

Example Project Instructions:


You are an assistant for AgentSetupSG, a Singapore-based digital brand that 
creates AI playbooks and prompt packs for Singapore professionals and 
small business owners. 

Our audience is beginners and intermediate users who are not technical. 
They speak Singapore English. Our brand tone is practical, direct, and 
encourages action. We do not use jargon.

When writing for our website or social media, always:
- Use short sentences and paragraphs
- Avoid corporate-speak
- Include Singapore-specific examples where relevant
- End with a clear action step

You can also add reference documents to the Project (your website copy, brand guidelines, product catalogue, etc.)

From now on, every conversation in this Project remembers your business context.

Step 4: Upload Documents to Claude

On the Pro plan, you can upload files directly into conversations.

How to upload:

In any conversation, click the **paperclip icon** at the bottom of the chat
Select your file (PDF, Word doc, text file, or image)
Claude will read the entire document and you can ask questions about it

What to try first:

Upload a long contract and ask “What are the key obligations I need to fulfil under this contract?”
Upload your latest business proposal and ask “What is weak in this proposal? How can I make the argument stronger?”
Upload your competitor’s website content (copy-paste it) and ask “What topics are they covering that I am missing?”

Step 5: Write Your First Business Prompts

The quality of your output depends on how you instruct Claude. Here are templates for common business tasks:

Email drafting:


Write a professional email to a potential B2B client in Singapore. 
Context: I sell [product/service]. They enquired about pricing last week 
but have not replied to my follow-up. 
Goal: Re-engage them without being pushy. 
Tone: Warm and confident. Length: under 150 words.

Proposal writing:


Write a one-page proposal for [project name]. 
Client: [brief description of client]
What we are proposing: [describe the work]
Price: [your price]
Timeline: [your timeline]
Tone: Professional but approachable. Format it with clear sections.

Meeting summary:


Below are rough notes from a client meeting. 
Write a clean meeting summary with:
- Key decisions made
- Action items with owner names
- Next steps and deadlines
Format as a short professional document I can email to the client.

Notes: [paste your notes]

Go to **API Keys** and create a new key
Add billing details – you pay per use based on tokens (roughly per 1,000 words processed)
Use the API key in your code, Make.com, n8n, or other automation tools

Cost guide:

Claude Sonnet 4.5 (fast and capable): around USD $0.003 per 1,000 input tokens

For typical business automation, costs run USD $5 to $30 per month

Quick Wins to Try in Your First Week

**Summarise a document:** Upload your longest, most painful-to-read document and ask Claude to give you the top 5 things you need to know from it.

**Rewrite your website’s About page:** Paste your current About page text and ask Claude to make it clearer, more compelling, and focused on customer benefits rather than company history.

**Audit your email templates:** Paste your standard customer email templates and ask Claude to identify which ones sound cold or unclear, and rewrite them.

**Draft a difficult conversation:** Describe a difficult business conversation you need to have (with a supplier, a difficult client, or a staff member) and ask Claude to help you plan what to say.
