Got Questions?
Frequently Asked Questions
Clear, direct answers regarding custom PHP development services in Delhi NCR and across India.
Why should I choose custom PHP development over CMS like WordPress?
While CMS platforms are great for standard content websites, custom PHP is essential when your business requires unique workflows, custom database structures, private CRM/ERP portals, or maximum execution speed without unnecessary third-party plugins and bloat.
How much does custom PHP application development cost in Delhi NCR, India?
The cost depends on functional complexity, database scale, user permission tiers, and third-party API requirements. Brand Promotionwala offers transparent, milestone-based pricing suited for startups, MSMEs, and enterprises across India with zero hidden charges.
How long does it take to develop a custom PHP application?
A standard custom PHP business portal or CRM typically takes 2 to 4 weeks. Larger multi-role enterprise web applications, marketplaces, or ERP systems with custom integrations generally require 4 to 8 weeks depending on project scope.
How do you ensure data security in custom PHP applications?
We adhere to strict OWASP security standards: all database interactions use PDO with prepared statements to prevent SQL injections, input sanitization prevents XSS attacks, session data is encrypted, and sensitive endpoints are protected by CSRF tokens and rate limiting.
Can you upgrade my older PHP 5.x or 7.x application to PHP 8.x?
Yes. We specialize in refactoring and modernizing legacy PHP applications. We update deprecated functions, optimize legacy SQL queries, and configure modern PHP 8.x execution environments with zero loss of existing business data.
Who owns the source code once development is complete?
You have 100% full intellectual property (IP) ownership of the source code. Upon project completion and final handover, we provide clean, documented code repositories and database schemas with zero vendor lock-in.
