2. Project Description, Target Environment & Deliverables

• • Discipline: [e.g., Custom PaperMC Plugin / Next.js Website / UI/UX Design / Performance Audit]
• • Target Platform & Runtime: [e.g., PaperMC 1.21.4, Java 21, MySQL 8.0, Redis / Next.js 15]

• • Deliverable 01: [Detailed functional description of feature/module 1]
• • Deliverable 02: [Detailed functional description of feature/module 2]
• • Deliverable 03: [Compiled .jar / Git Source Repository / Configuration & Setup Guide]

3. Explicit Scope Exclusions

To keep pricing predictable, anything not listed in Section 2 is excluded unless added via a written Change Request. Specifically excluded from this Agreement:

• [e.g., Custom 3D Blockbench models, resource pack pixel art, or audio assets unless supplied by Client]
• [e.g., Ongoing Linux VPS system administration or DDoS firewall management after deployment]
• [e.g., Compatibility rewrites for future unreleased Minecraft versions beyond the Target Platform in Section 2]

4. Price, Milestones, Acceptance Criteria & Taxes

Total Fixed Project Fee: [CURRENCY & AMOUNT, e.g., $250.00 USD] payable via [PAYMENT METHOD, e.g., PayPal Invoice / Wise / Bank Transfer]. Unless a Goods and Services Tax Identification Number (GSTIN) is explicitly stated on an invoice, the Primary Contracting Operator operates below the mandatory GST registration threshold under Section 22 of the Central Goods and Services Tax Act, 2017 (India), and no GST is charged or collected.

Acceptance Procedure: Client has seven (7) calendar days from delivery of each milestone to inspect and report any reproducible failure to meet Section 2 specifications. Deliverables are deemed accepted upon written approval, live production deployment, or expiration of the 7-day review window without a written defect report.

5. Client Responsibilities, Revisions & Change Requests

Client will provide required configuration files, test environment access, and assets within 3 business days of request. Delivery dates extend day-for-day for Client delays. This project includes [2] rounds of minor adjustments within the agreed scope. Any additional features or architecture alterations require a written Change Request specifying the added fee and timeline adjustment.

6. Delivery Format, Source Code & Documentation

Upon receipt of the Final Delivery payment (M3), Developer will deliver: [X] Compiled production artifact (.jar / web build), [X] Private Git repository / complete source code with Gradle/Maven/npm build scripts, and [X] Default annotated configuration files & permission/command reference.

7. Intellectual Property Ownership & Licensing Election

Subject to Client's full payment of all fees under Section 4 (Check one agreed option):

• [X] OPTION A — Full Assignment of Bespoke Code (Standard Commission): Developer assigns to Client all worldwide, perpetual right, title, and copyright in the bespoke Foreground IP created specifically for this project. The parties explicitly agree that this assignment shall NOT lapse under Section 19(4) of the Indian Copyright Act, 1957 and is perpetual and worldwide under Sections 19(5)–(6).
• [ ] OPTION B — Exclusive / Non-Exclusive Custom License:Developer retains copyright ownership of the codebase and grants Client a perpetual, worldwide, [exclusive / non-exclusive], royalty-free license to deploy and modify the deliverable across Client's network.

Background IP & Open Source: Developer retains ownership of pre-existing utility libraries, boilerplate frameworks, and tools (“Background IP”), granting Client an irrevocable, perpetual, worldwide, royalty-free license to use and modify such Background IP within the Deliverable. Upstream open-source APIs (PaperMC, Velocity, React, etc.) remain governed by their respective open-source licenses. Portfolio attribution is [Permitted / Restricted under NDA].

8. Cancellation, Suspension & Work Completed

If Client cancels before work commences, 100% of the deposit is refunded (less actual non-recoverable payment gateway fees). If Client cancels mid-project, Developer will halt work, calculate the pro-rata value of hours/modules actually completed and documented up to the cancellation notice, deliver the paid-for work-in-progress, and refund any unearned prepayment balance. If Developer fails to deliver due to Developer fault, Client receives a 100% refund for undelivered milestones.

9. Post-Delivery Bug-Fix Warranty (30 Days)

Developer warrants that for thirty (30) calendar days following delivery of M3, Developer will patch at no charge any reproducible bug where the Deliverable fails to operate in accordance with Section 2 on the specified Target Platform. This warranty does not cover issues caused by Client code edits, unsupported server forks, or third-party API changes after delivery.

10. Confidentiality, Server Credentials & Production Backup Responsibility

Confidentiality: Both parties agree to keep private server architectures, unreleased game mechanics, source code, and business credentials strictly confidential.

Security & Backups: Client should provide temporary, least-privilege staging/panel access rather than root passwords wherever possible, and must rotate credentials upon project completion. Client is solely responsible for taking a complete, verified backup of all production server worlds, databases, and configurations prior to deploying any Deliverable.

11. Limitation of Liability & Dispute Resolution

Except for liability that cannot lawfully be excluded (such as fraud, willful misconduct, or mandatory statutory consumer rights), neither party shall be liable for indirect or consequential damages (including lost server donations or player counts), and Developer's maximum aggregate liability under this Agreement shall not exceed 100% of the total fees paid by Client under this SOW. This Agreement incorporates the OneStudio Terms of Service (/terms) and is governed by the laws of India (courts of Pune, Maharastra, India), without prejudice to mandatory consumer protections in Client's country of residence.
