4.3. Service Subscription & Receipts (My Subscription) Guide

This is the management menu where a company or individual can review the details of their active TFlow license plan, understand feature usage limits, and download recurring-payment invoices.

⚠️ Only users granted Admin privileges can access the features to change billing options or add a paid payment method.

1. Reviewing Current Usage and Plan

• License info: Monitor your currently granted workspace size (Basic / Pro / Enterprise), cloud document storage limit, AI email analysis count, and PoF smart-lock issuance limit as graphs.
• Expiry display (Expiry / Billing Cycle): Shows the upcoming renewal date on which your next card payment will occur, or the renewal deadline of your enterprise annual license.

AI Token Balance

TFlow's AI features (Lyra chatbot, CYGNUS analysis, LEO analysis, etc.) run on a Token Balance basis.

• Check balance: Your current AI token balance is shown as a gauge in the top navigation bar.
• Automatic deduction: Usage is automatically deducted when an AI analysis pipeline (CYGNUS, etc.) completes.
• When the balance is low: When the balance drops to 0 or below, AI analysis features are restricted. Ask your administrator to top up tokens.
• Baseline allowance: Even after the subscription expires, a small amount (about 100,000) of tokens is granted daily by default, enabling limited AI search.

2. External Integration

Manage the API key (PAT) used to access TFlow data from external AI chatbots such as Claude Desktop and ChatGPT.

• Issue an API key: In the External Integration tab, click the Issue API Key button to generate a key in the form pat_tflow_....
• Handle the key carefully: The issued key is shown only once. Be sure to copy and store it somewhere safe.
• Validity period: The default is 90 days; reissue is required after expiry.
• Reissue: If you lose or expire an existing key, click the Reissue button to immediately revoke the old key and issue a new one.
• Copy Claude Desktop config: With one button, you can copy the JSON configuration for Claude Desktop to your clipboard.

💡 For how to set up external integration, see the MCP Integration Guide.

3. Receipts and Invoice History

• Payment history list: Review the billing items approved via monthly recurring payment over the past 12 months and their status (Paid, Failed).
• Print evidence: For management-department settlement, etc., click the view feature or download button to the right of each payment record to directly obtain the PDF invoice/receipt. The document is auto-filled with company info, Tax ID, etc.

3-1. Subscription & Billing Evidence Troubleshooting (FAQ)

• Q: "The AI mail analysis feature stopped. It says Limit Exceeded."
  • Error code/symptom: PLAN_LIMIT_REACHED_AI_QUOTA
  • A: You have used up all of your current plan's monthly AI sentence-analysis quota. Usage is restricted until the reset on the 1st of next month; for additional use, the administrator must raise the payment tier via Upgrade Plan.
• Q: "I clicked the receipt page but get redirected saying I'm unauthorized."
  • Error code/symptom: UNAUTHORIZED_ACCESS_BILLING
  • A: Per system permissions, viewing and downloading invoices is accessible only to the roles responsible for cost settlement (Admin or Accountant). Please obtain it from the person in overall charge at your company.
• Q: "When my subscription plan expires or is canceled, what happens to my existing project files?"
  • Error code/symptom: SUBSCRIPTION_EXPIRED_READONLY
  • A: System access is not completely blocked; your account and project data are kept in a read-only state. Also, even if you access without paying, a small amount (about 100,000) of AI search tokens is granted daily by default, allowing limited review.
