Bespoke PHP, Web Portals & API Engineering • Delhi NCR & Global
Custom web development services built around your exact operations.
Off-the-shelf themes and stacked plugins break down fast when your business needs custom pricing calculators, multi-city portals, role-based dashboards, or live CRM sync. At Sync Soft Solution in New Delhi, we engineer fast, maintainable custom websites and web applications with 100% source-code ownership.
01 / When templates fall short
Engineered around how your business actually runs.
Standard CMS templates force your team to bend internal operations around rigid plugin limits—leading to sluggish mobile Core Web Vitals, security vulnerabilities, and fragile workarounds every time a plugin updates.
We build clean, modular PHP, MySQL, and modern JavaScript architectures tailored to your exact data model and customer journey. Need a straightforward content site or standard online catalog instead? Compare our WordPress development, Shopify & WooCommerce stores, or standard website design packages in Delhi.

Frequently asked questions
Straight answers before
commissioning custom code.
How much does custom website or web portal development cost in Delhi?
At Sync Soft Solution, lightweight custom-coded PHP business websites (8–12 pages) start from ₹21,999 + 18% GST, larger dynamic multi-location or corporate architectures start from ₹44,999 + GST, and full custom web portals, calculators, or multi-role applications start from ₹85,000 + GST depending on database and API scope.
When should I choose custom PHP development over WordPress or Shopify?
Choose WordPress or Shopify for standard blogs, simple brochure sites, or typical retail catalogs. Choose custom development when you need sub-second page speed across dozens of location/route templates, custom pricing or logistics calculators, multi-vendor wallets, bespoke user dashboards, or strict security without third-party plugin bloat.
Can you upgrade, fix, or integrate with our existing PHP or legacy system?
Yes. Our engineers regularly audit existing PHP/MySQL codebases, Windows IIS (`web.config`), and Linux Apache/Nginx environments—fixing URL routing leaks, refactoring slow queries, adding payment/CRM APIs, or migrating legacy sites safely without dropping Google rankings.
Will our non-technical team still be able to edit text, prices, or pages?
Yes. Custom doesn't mean hard to manage. Where your team needs regular control—such as updating service rates, adding city pages, publishing insights, or exporting leads—we build clean, role-restricted admin panels tailored strictly to what your staff uses, without confusing menus.
Are custom-coded websites better for Google SEO and AI search (GEO)?
Often yes, because you have 100% control over HTML cleanliness, Core Web Vitals speed, server-level URL rewrites, canonical headers, and custom JSON-LD schema—making it effortless for Googlebot, ChatGPT, and Perplexity to crawl and cite your pages.
Who owns the source code, database, and server credentials after launch?
You retain 100% ownership of the custom source code, database, domain, and cloud/VPS hosting upon final milestone completion. We never lock clients into proprietary encrypted frameworks or mandatory agency hosting.
