FAQ
Can you develop a completely new Perfex CRM module?
Yes, I build custom Perfex CRM modules from scratch based on your exact requirements from simple feature additions to complex business logic.
Can you build AI-powered automation in Perfex CRM, or connect it with n8n, Zapier, or Make?
Yes, I integrate AI tools like GPT-4, Claude, or Gemini directly into Perfex CRM, and connect it with automation platforms like n8n, Zapier, or Make for workflows such as auto-lead-scoring, WhatsApp notifications, or smart follow-ups.
Can you convert Perfex CRM into a SaaS platform?
Yes, I convert single-tenant Perfex CRM installs into multi-tenant SaaS platforms, including tenant isolation, subscription billing, and scalable architecture.
Can you integrate Perfex CRM with third-party APIs?
Yes, I've integrated Perfex CRM with payment gateways (Stripe, USAePay, Payrexx), messaging platforms (WhatsApp, Twilio), and many other third-party APIs.
Can you customize Perfex CRM workflows according to my business process?
Yes, I tailor CRM workflows approvals, notifications, task automation to match how your team actually operates, not a generic template.
Is SaaS conversion a small customization or a custom project?
SaaS conversion is a larger custom project, typically scoped under my Premium package, since it involves architecture changes rather than a single feature.
Do I need to give you access to my Perfex CRM installation?
Yes, for most projects I'll need admin/FTP access to your server or a staging copy. I sign an NDA on request and never touch production without your confirmation first.
What if I need support after delivery?
All packages include post-delivery support (30 days on Basic/Standard, 60 days on Premium) for bug fixes related to the delivered work.
