⚠️ Treat as Real Client Matter

Although this is opposing counsel's letter, it still contains information about our client matter. Apply appropriate confidentiality analysis before using any tool.

Tool Selection Opportunity

Task: Analyze opposing counsel's arguments, identify weaknesses, draft response letter

Non-AI Options
  • Manual analysis of legal arguments with legal research
  • Response letter templates from practice guides
  • Secondary sources on demand letter strategy and response
AI Options (Tools You Have)
  • CoCounsel/Protégé: Document analysis and drafting within privileged platforms
  • Gemini/Copilot: Could analyze general demand letter structure or legal arguments—but what client information would you share?
Selection Considerations
  • The letter contains matter-specific details (party names, amounts, contract terms)
  • Could you ask general questions about responding to demand letters without sharing specifics?
  • For drafting a response, what verification would you need to perform on AI-generated content?
  • What tone is appropriate? Consider: the goal is to protect the client's interests, not to "win" the letter exchange

Re: Demand for Payment – Vertex Solutions LLC v. GreenLeaf Technologies, Inc.

Dear Ms. Chen:

This firm represents Vertex Solutions LLC ("Vertex") in connection with the Software Development Agreement dated September 8, 2025 (the "Agreement") between Vertex and GreenLeaf Technologies, Inc. ("GreenLeaf").

STATEMENT OF FACTS

Pursuant to the Agreement, Vertex agreed to develop custom inventory management software for GreenLeaf for a total fee of $180,000. Vertex fully performed its obligations under the Agreement, delivering the completed software on January 15, 2026—the contractual deadline. GreenLeaf has paid only $120,000, leaving a balance of $60,000 due and owing.

BREACH OF CONTRACT

GreenLeaf's refusal to pay the remaining $60,000 constitutes a material breach of the Agreement. The software delivered by Vertex conforms to the specifications set forth in Exhibit A to the Agreement. GreenLeaf's complaints regarding inventory accuracy and reporting capacity are not supported by the contract terms:

  1. Inventory Accuracy: The specifications require the software to "maintain accuracy within acceptable industry tolerances." Vertex's software meets this standard. GreenLeaf's claimed discrepancies, if they exist, likely result from user error or improper system configuration.
  2. Reporting Capacity: The specifications do not guarantee any minimum report size or enterprise-level reporting capabilities. The reporting function performs as designed for standard business reporting needs.

DEMAND FOR PAYMENT

Demand is hereby made for immediate payment of:

Principal balance due: $60,000.00
Interest (1.5% per month from January 15, 2026): $1,050.00
Total Amount Due: $61,050.00

Interest will continue to accrue at the contractual rate until payment is received in full.

LITIGATION WARNING

If payment is not received within fourteen (14) days of the date of this letter, Vertex will file suit against GreenLeaf in the appropriate Texas court seeking:

  1. The unpaid contract balance plus accrued interest;
  2. Attorneys' fees and costs as provided in Section 8.4 of the Agreement; and
  3. All other relief to which Vertex may be entitled.

Please govern yourself accordingly.

Very truly yours,

HARRISON & COLE LLP
