Honest, Fixed-Scope Engineering.
Zero Hidden Surcharges.
Every Zelvori package has explicit limits, documented deliverables, and direct pass-through cloud costs. No inflated hosting markups, no hostage code.
Explicit Line-Item Limits

Third-Party Infrastructure Pass-Through Rules
Many traditional agencies bundle hosting into opaque monthly fees with heavy markups. At Zelvori, you retain 100% direct ownership of every cloud account and pay suppliers at wholesale market rates.
| Cost Category | Common Providers | Estimated Cost | Billing & Ownership Model |
|---|---|---|---|
| Domain Registration | Name.com / Cloudflare / GoDaddy | ₹800 – ₹1,500 / year (typical .com / .software) | Billed directly to client credit card. Client maintains 100% legal registrant ownership. |
| Application Hosting | Vercel / Cloudflare Pages / AWS / Hetzner | ₹0 (Free tier) to ₹1,800 / month (Pro plans) | Direct account with host. Zelvori configures deployment pipelines without hosting markups. |
| Database & Backend | Supabase / Neon / AWS RDS / DigitalOcean | ₹0 to ₹2,500 / month depending on storage & compute | Client provisions or links credit card directly to their cloud database console. |
| Payment Gateways | Razorpay / Cashfree / Stripe | Standard 2% transaction fee (no monthly software fee) | Merchant payout settlements flow directly into the client's verified corporate bank account. |
| AI / LLM API Tokens | Google Gemini / OpenAI / Anthropic | Usage-based (e.g. ₹0.10 – ₹5 per 1,000 tokens) | Client supplies developer API keys. Zero token surcharge or proxy markup. |
| Mobile App Developer Fees | Apple Developer / Google Play Console | Apple: $99/year (~₹8,300) | Google: $25 one-time (~₹2,100) | Paid directly to Apple and Google for organizational publisher verification. |
International Clients (US, UK, Europe & Middle East)
For clients based outside India, we provide bespoke Statements of Work in USD ($), EUR (€), or GBP (£). International rates account for cross-border invoicing compliance, GST export exemptions under Letter of Undertaking (LUT), tailored international wire settlements, and dedicated timezone coordination with our senior engineering team.
What Makes Zelvori Different
Compare our engineered methodology against standard agency practices and unpredictable freelancer arrangements.
| Engineering Decision | Traditional Agency | Freelancer | Zelvori Practice |
|---|---|---|---|
| Scope & Deliverables | Vague estimates that lead to scope creep and surprise add-on invoices. | Unpredictable scope boundaries and ad-hoc communication. | Fixed Statement of Work (SOW) with line-item screen counts, limits, and exclusions. |
| Infrastructure & Hosting | Marked up 200–400% on monthly retainers, locking you into their servers. | Unmanaged personal server setups with zero documentation. | Direct pass-through. You own all cloud accounts, domain registrations, and API keys. |
| Progress Verification | Static screenshots and progress reports with weeks of radio silence. | Local screenshots without staged testing environments. | Interactive preview prototypes, staged preview branches, and weekly verified milestones. |
| Intellectual Property | Proprietary themes with restricted license keys and code lock-in. | Ambiguous IP ownership and informal GitHub transfers. | 100% full IP ownership, unencumbered source code, design files, and documentation. |
| Post-Launch Warranty | Immediate billing of expensive hourly maintenance retainers. | Disappears or takes weeks to respond to post-launch regressions. | Complimentary 30-day bug-fix warranty on all agreed specifications. |
Milestone SOW & Delivery Roadmap
How every engagement moves from formal specification to verified production deployment.
Discovery & Fixed-Scope SOW
We finalize page counts, user journeys, data models, and pass-through requirements. You receive a binding, transparent Statement of Work with zero ambiguity.
Design Tokens & Interactive Preview
We construct verified Figma or code components. You test interactive flows in a live sandbox before backend construction starts.
Engineered Sprints & Staging Builds
Feature development on dedicated feature branches. Bi-weekly preview deployments allow you to inspect progress on real devices.
Security Audit & Final Launch
SAST code scan, Lighthouse optimization, DNS mapping to your production domain, and full repository transfer with 30 days warranty support.
Zelvori Application Security services consist of static code analysis (SAST), dependency auditing, HTTP header hardening, architectural threat modeling, and OWASP Top 10 code remediation. These reviews do not constitute an active third-party network penetration test, CREST accreditation, 24/7 Security Operations Center (SOC) monitoring, or ISO/SOC 2 formal compliance certification.
All listed package prices, effort timelines, and warranty terms represent baseline engineering benchmarks. Engagements are customized to client specifications and formalized under a signed Statement of Work (SOW) approved by the Zelvori project owner prior to project commencement.
