FAQs

Frequently Asked Questions

Answers to common questions regarding custom services and development.

How does the quote and payment process work?
Once you submit an inquiry or reach out via WhatsApp/Telegram, we evaluate your requirements and provide a fixed-price proposal and delivery timeline. For custom development, work typically starts with a 50% milestone deposit, with the remainder due upon demo approval.
Do you provide post-delivery support and revisions?
Yes! Every development service includes 14 to 30 days of complimentary post-launch support and bug fixes to ensure everything runs flawlessly in your production environment.
Can you customize scripts purchased from other marketplaces?
Absolutely. We routinely customize scripts from CodeCanyon, GitHub, ScriptNest, and proprietary codebases, regardless of whether the original author is still active.
Will my confidential source code and database remain secure?
100%. We adhere to strict confidentiality practices, never disclose your proprietary logic, and sign Non-Disclosure Agreements (NDAs) upon request prior to accessing your repository.
Can we communicate directly on WhatsApp or Telegram?
Yes! For rapid communication and instant status updates, we are readily available on WhatsApp and Telegram during project development.
