From Claude Sign-Up to the Value of the $200 Pro Plan: A Complete Setup Guide
Why Claude? What to Know Before You Start
Since 2024, Anthropic’s Claude has grown its presence faster than any other tool in the generative AI market. For B2B sales reps and office workers in particular, the reasons Claude stands out are clear.
Long-context handling: Up to 200K tokens — read and summarize a 100-page RFP document in one go.
Projects: Build a customized AI workspace for your recurring tasks.
Artifacts: Generate and edit code, documents, tables, and visualizations in real time.
Safety: A policy of not using business data for training (on the Pro plan).
Before: Using only ChatGPT → long documents had to be split up, and context was often lost
After: Using Claude Pro → upload a 100-page proposal whole and get the key points summarized in 3 minutes

Step 2. Plans Compared in Full
2-1. The three plans at a glance (as of 2025)
Item | Free | Pro ($20/month) | Max ($100–200/month) |
|---|---|---|---|
Model | Claude 3.5 Sonnet | Claude 4 Opus / Sonnet | Claude 4 Opus / Sonnet |
Daily messages | Limited (about 10–30) | 5x or more | Nearly unlimited |
File uploads | ✅ (limited) | ✅ (large files) | ✅ (large files) |
Projects | ❌ | ✅ | ✅ |
Artifacts | Limited | ✅ Full features | ✅ Full features |
Extended Thinking | ❌ | ✅ | ✅ (longer thinking) |
Priority access | ❌ | ✅ | ✅ |
Excluded from data training | ❌ | ✅ | ✅ |
2-2. Why B2B Sales Reps Need the Pro Plan
Let’s look at the real-world limits of the Free plan.
Draft a proposal in the morning (15 messages used up) → then try to write a customer email in the afternoon and get a “message limit exceeded” notice
Upload a PDF and ask for analysis, and just 3–4 complex questions hit the daily limit
During peak traffic hours (9–11 a.m.), access slows down or is blocked
Before (Free plan): about 30 minutes of usable AI time per day, with important work interrupted by limits
After (Pro plan): uninterrupted use all day, about 3–4 hours of AI time, and 2–3x more work done
2-3. When Is the $200/Month Max Plan Worth It?
The key to the Max plan is expanded Extended Thinking and nearly unlimited messages.
Consider the Max plan if two or more of the following apply to you.
You chat with Claude 100+ times a day.
You analyze contracts or technical documents of 30+ pages every day.
You run complex data analysis (sales forecasts, competitor comparison tables, etc.) 3+ times a week.
You use code generation and debugging routinely.
💡 Practical tip: Start with the Pro plan ($20/month) and monitor your usage for two weeks. If you see a “You’re approaching your message limit” notice 3+ times a week, it’s time to switch to Max.
Step 3. Subscribe to the Pro Plan (3 minutes)
3-1. Upgrade Steps
While logged in to claude.ai, click your name (or icon) at the bottom left.
In the dropdown menu, click “Upgrade to Pro” or “Subscription.”
On the plan selection screen, click the “Subscribe” button on the “Pro — $20/month” card.
Enter your payment details:
16-digit card number
Expiration date (MM/YY)
3-digit CVC
Billing address: if you’re entering a Korean address, select Country: South Korea and enter the address in English
Click “Subscribe” → the Pro plan activates immediately
💡 Practical tip: Use a credit card that supports international payments (VISA, MasterCard). Some debit cards block international payments by default, so first enable “international online payments” in your card issuer’s app.
3-2. Checking Your Subscription and Receipts
Click your name at the bottom left → “Settings” → the “Billing” tab to see your current plan, next billing date, and payment history.
If you need a PDF receipt, click “Download invoice” to the right of the relevant payment. It’s useful for expense reports after paying with a corporate card.
Step 4. Set Up Projects — Your Own AI Workspace
4-1. What Are Projects?
Projects are AI workspaces optimized for a specific kind of work. Unlike a regular chat, a project lets you preconfigure the following.
Custom Instructions (system prompt): Define Claude’s role, tone, and output format
Knowledge (reference documents): Upload PDF, TXT, or CSV files so Claude can refer to them at all times
Before: Retyping “You are a B2B sales expert, use this document” in every conversation
After: Set it up once in a Project → it applies automatically to every conversation, saving 2–3 minutes at the start of each chat
4-2. Hands-On: Create a Project
Click “Projects” in the left sidebar.
Click the “Create project” button.
Enter a project name, for example:
Customer Proposal WriterEnter a Description, for example:
Project for drafting B2B sales proposals for IT solutionsClick “Create” to open the project screen.
4-3. Set Up Custom Instructions
On the right side of the project screen, click “Set custom instructions” (or the pencil icon) and enter the following.
Custom Instructions Example: B2B Proposal Writer
You are a specialist writer of B2B sales proposals for IT solutions.
Always follow these rules:
Structure every proposal as [Problem Definition → Solution Overview → Expected Benefits → ROI Figures → Next Steps].
Include specific examples and figures relevant to the client’s industry.
Use a professional yet easy-to-read, polite tone.
Put key figures in bold (**).
Always give priority to the uploaded Knowledge documents.
Click “Save”.
4-4. Upload Documents to Knowledge
On the project screen, click “Add content” → “Upload files”
Select the files to upload (up to 30 MB per file and about 200K tokens per project)
Recommended documents to upload:
Document Type | Example | Benefit |
|---|---|---|
Company profile PDF |
| Accurately reflects your company’s information |
Product spec sheet |
| Prevents technical specification errors |
Case study collection |
| Automatically cites real cases in proposals |
Pricing policy |
| Applies accurate prices when drafting quotes |
Competitor comparison table |
| Automatically surfaces differentiators |
💡 Pro tip: Put a competitor comparison table in Knowledge, and when a customer asks, "Why should we choose you over Company A?", Claude can instantly generate the response material you need.
4-5. Start a Conversation Inside the Project
Type a prompt into the input box at the bottom of the project screen. Let's try the first exercise.
Prompt Example 1 — Generate a Proposal Draft
Write a draft proposal for adopting a cloud ERP, aimed at a mid-sized manufacturer (KRW 50 billion (≈ US$37,408,300) in annual revenue, 300 employees).
Customer's key pain points: a 15% average monthly inventory error rate from manual inventory management, and data silos between departments.
Reflect the product specs and success stories uploaded to Knowledge.
Claude instantly generates a proposal draft following the structure you set in Custom Instructions (problem definition → solution → expected benefits → ROI → next steps).
Step 5. Use Artifacts — A Tool That Creates Deliverables Instantly
5-1. What Are Artifacts?
Artifacts are standalone output panels that Claude creates during a conversation. They appear in a separate area on the right side of the chat window and can contain the following:
Documents: Markdown-formatted reports, emails, and proposals
Code: Executable code in Python, JavaScript, and more
HTML/React: Interactive web elements and dashboards
SVG: Diagrams and flowcharts
Tables/Charts: Data visualization
5-2. Confirm Artifacts Is Enabled
After you subscribe to the Pro plan, Artifacts is enabled by default. To check:
Click your name at the bottom left → "Settings"
Check that "Feature Preview" or "Artifacts" is set to "On"
If it's Off, click the toggle to enable it
5-3. Practical Examples
Example A: Generate a Competitor Comparison Table
Prompt Example 2 — Competitor Comparison Artifact
Create an Artifact with a table comparing our product (CloudERP Pro) against three competitors (SAP Business One, Oracle NetSuite, Douzone ERP).
Comparison criteria: price range, implementation time, Korean-language support, customization difficulty, mobile support, and customer ratings.
Mark the criteria where our product leads in green and those where it trails in red.
Claude generates a color-coded HTML comparison table in the Artifact panel on the right. You can copy it with the "Copy" button or save it with "Download".
Example B: Generate a Sales Email Sequence
Prompt Example 3 — Cold Email Sequence
Create an Artifact with a three-step email sequence for a manufacturing IT manager who has shown interest in cloud ERP.
Email 1: First contact (empathize with pain points + introduce the solution)
Email 2: 3 days after Email 1 (share a success story + offer a demo)
Email 3: 5 days after Email 2 (limited-time offer + CTA to confirm a meeting)
Include a subject line, body, and CTA button text for each email.
Before: 30 minutes to write one email, 2 hours to finish a 3-email sequence
After: A 3-email sequence done in 5 minutes, under 15 minutes even with revisions
5-4. Edit and Iterate on an Artifact
If an Artifact needs further changes after it's generated, just ask in the chat window.
"Make the tone of Email 2 a bit more casual"
“Add an ‘on-premises integration support’ row to the comparison table.”
“Convert the prices in the table to Korean won (₩).”
Claude edits an existing Artifact by saving it as a new version. You can compare earlier and current versions using the left and right arrows.
💡 Pro tip: Take a screenshot of the HTML comparison table you built as an Artifact and drop it straight into your client presentation. You get a professional-looking visual on the spot, with no request to the design team.
Step 6. Advanced Setup to Maximize Your Efficiency
6-1. Recommended Project Folder Structure
If you work in B2B sales, we recommend the following project structure.
📁 Proposal Writer — Custom Instructions: Expert proposal writer
📁 Client Emails — Custom Instructions: Sales communication specialist
📁 Meeting Notes — Custom Instructions: Summarize meeting notes and extract action items
📁 Market Research — Custom Instructions: IT industry research analyst
📁 Contract Review — Custom Instructions: Business contract review assistant
6-2. How to Use Extended Thinking
The Pro plan’s Extended Thinking feature is a mode in which Claude reasons more deeply behind the scenes before it answers.
How to turn it on: Click the 💭 icon on the left of the chat input box (or switch on the “Extended thinking” toggle in the model selector dropdown).
When to use it:
Risk clause analysis of contracts over 30 pages
ROI calculations for complex pricing scenarios
Building a differentiation strategy for competitive bids
Before (standard mode): Contract risk analysis → a list of 3–5 key points, surface-level
After (Extended Thinking): Contract risk analysis → 10–15 clause-by-clause risks identified, with suggested revisions and even a negotiation strategy
6-3. Work Faster with Keyboard Shortcuts
Shortcut | Function | Time saved |
|---|---|---|
/ (slash) | Start a new chat | No need to reach for the mouse every time |
Ctrl + Shift + C | Copy the last response | Saves time over drag-selecting |
Ctrl + Enter | Send without a line break | Prevents accidental sends |
Step 7. ROI Calculation — Is the $20 Pro Plan Really Worth It?
7-1. Concrete Time Savings
Task | Time on Free plan | Time on Pro plan | Hours saved per month |
|---|---|---|---|
Proposal first draft (twice a week) | 2 hours × 8 times = 16 hours | 30 minutes × 8 times = 4 hours | 12 hours |
Customer emails (10 per week) | 30 min × 40 emails = 20 hours | 10 min × 40 emails = 6.7 hours | 13.3 hours |
Meeting minutes (3 per week) | 40 min × 12 meetings = 8 hours | 10 min × 12 meetings = 2 hours | 6 hours |
Market research (2 per month) | 4 hours × 2 = 8 hours | 1 hour × 2 = 2 hours | 6 hours |
Total | 52 hours/month | 14.7 hours/month | 37.3 hours/month |
7-2. Converting time to money
Time saved per month: 37.3 hours
Average office worker hourly wage (pre-tax): about KRW 25,000 (≈ US$19)
Value saved per month: 37.3 × 25,000 = about KRW 932,500 (≈ US$700)
Pro plan cost: about KRW 28,000 (≈ US$21) (at KRW 1,400 (≈ US$1) per US dollar)
ROI: about 33x (932,500 ÷ 28,000)
💡 Practical tip: When you ask your manager or executives to approve a corporate-card payment, use the table above as it is. One sentence — “For about KRW 28,000 (≈ US$21) a month, we can free up 37 hours of work time” — greatly improves your odds of approval.
