## 1. Do They Deliver Full Source Code & IP Ownership? - **Red Flag:** Agencies that lock your website into proprietary servers or refuse to hand over Git repositories unless you pay an "exit fee". - **Green Flag:** Full source code transfer upon final payment, with complete rights to host on any cloud provider (AWS, Vercel, VPS).

## 2. What Technology Stack Do They Build On? - **Red Flag:** Agencies that default to outdated WordPress/PHP themes with 40+ third-party plugins. - **Green Flag:** Modern full-stack frameworks like **Next.js 16**, TypeScript, and Tailwind CSS engineered for 95+ Google PageSpeed scores.

## 3. Are Pricing & Deliverables Itemized Transparently? - **Red Flag:** Vague quotations like *"Complete Custom Website — Contact for Quote"* without specified page counts, revision cycles, or timeline SLAs. - **Green Flag:** Clear tiered packages with exact deliverable checklists, delivery SLAs in business days, and clear add-on rates.

## 4. Do They Provide Official GST Tax Invoices? - **Red Flag:** Cash-only or personal UPI transfers without formal business GSTIN documentation. - **Green Flag:** Proper GST Tax Invoices detailing registered business addresses, HSN/SAC codes, and itemized scopes for corporate tax deductions.

## 5. What Post-Launch Support & Maintenance Do They Offer? - **Red Flag:** The agency disappears after final payment, leaving you without bug fix support. - **Green Flag:** Clear SLA guarantees (e.g., 30 days of complimentary bug-fix warranty) and optional monthly advance SEO/Ad management retainers.
