Perfex CRM development
Perfex CRM, adapted to the way your business actually works.
Perfex is flexible, but the value comes from configuring and extending it around your process — not forcing your team into the default setup. DevStacker installs, customizes, and builds custom modules for businesses that need more than an out-of-the-box configuration.
Perfex Core + Extensions
Perfex services
Grouped by what's actually being done.
Not every project includes every item below — scope is agreed based on what the business actually needs.
Installation & Foundation
Installation, branding, company settings, staff roles, email, and cron configuration.
Fields, Workflows & Portal
Custom fields, workflows, customer portal setup, dashboards, reports, and authentication.
Custom Modules
Custom modules, module modification, custom business logic, and custom interfaces.
Connected Systems
Website, APIs, email, payment systems, and automation tool integrations.
Fixes & Repairs
Broken modules, upgrade conflicts, errors, integration failures, and performance issues.
Custom module development
When a business process doesn't fit cleanly into the default CRM, a custom module can support it directly instead of forcing a workaround.
These are conceptual examples of what custom modules can support — not a portfolio of completed projects.
Modifying existing modules
Not every change belongs in core files.
There's a real difference between adjusting a setting, safely customizing behavior, extending a module, and modifying it directly — and the difference matters for how the installation holds up over time.
Where possible, we structure customization to reduce unnecessary upgrade conflicts — extending rather than editing core files whenever that's a realistic option. We don't promise zero conflicts; no honest approach to CRM customization can.
Already running Perfex?
We can work with what's already there.
You don't need to start over because DevStacker is involved. Often an existing installation just needs review and targeted fixes.
Perfex + website
A lead shouldn't need to be copied in by hand.
Perfex + automation
What happens after a status changes.
A status update, a new lead, or an overdue item in Perfex can trigger a notification or an external workflow — through webhook or API-driven automation, with tools like n8n where that's the right fit. What's actually possible depends on the hooks, APIs, or custom code available in a given setup; not every action exposes an integration point by default.
Customer portal
What a customer can see and do, on their own.
What's shown and what's editable depends on what's technically feasible and agreed in scope — not every portal customization is possible in every setup.
Authentication & access
Who can log in, and what they can see once they do.
This covers practical access control within the CRM — not a claim of enterprise identity or security certification.
Reports & dashboards
Default reports don't answer every question.
Perfex ships with standard reporting, but it won't always match how a specific business needs to see its own data. Where useful, we create or adapt operational reports, custom dashboards, filtered views, and business-specific metrics — built around what the team actually needs to track, not a generic template.
Integration architecture
Perfex is one system inside the wider stack.
Perfex is where customer information lives — it becomes more valuable connected to the site that generates leads, the automation that acts on them, and the tools the rest of the business already runs on.
Upgrades & maintainability
Solving today's problem shouldn't make tomorrow's update painful.
Tracked, Not Ignored
Core updates are reviewed for impact rather than applied blindly or avoided indefinitely.
Module Awareness
Custom and third-party modules are checked for compatibility before an update goes ahead.
Tested First, Where Appropriate
Changes are tested in a staging environment before touching the live installation, when the setup allows for it.
Before Anything Changes
A recovery point exists before an update or customization is applied.
Customizations on Record
What was changed and why is documented, so it's not a mystery for whoever maintains it next.
This reduces upgrade risk — it doesn't eliminate it. Compatibility with a future Perfex update can't be guaranteed in advance for any customization, by us or anyone else.
