Custom CRM and ERP

Custom CRM and ERP systems for connected operations

A generic CRM or ERP can be expensive and rigid, and your team may stop using it. We design one with the modules you need, connected to your sales channels and the information that helps you make decisions.

The problem

Signs you need it

If any of these situations sound familiar, you are leaving money on the table.

  • Leads get lost between WhatsApp, email, and notebooks.
  • You do not know each salesperson's results or where opportunities stand.
  • Inventory never matches what the system says.
  • Closing the month takes days of manual reconciliation.

Before you commission a project

Custom CRM and ERP development: modules, migration and investment

When it makes sense

A CRM organizes opportunities, tasks and sales history; an ERP connects inventory, purchasing and operations. We define each team’s information needs and the data modules must share before choosing the scope.

Systems and integrations

We assess WhatsApp, email and invoicing integrations. Migration from spreadsheets or another system requires agreed fields, duplicate handling, balances and sample validation before switching.

Timeline and validation

The schedule depends on modules and data readiness. Adoption is staged through a trial migration, training for process owners and rollout to an initial user group.

What determines investment

Pricing reflects workflows, permissions, reporting and integrations. Third-party licenses, invoicing and infrastructure are listed separately; owning a system does not eliminate every recurring cost.
