CRM / ERP Design / KNOWLEDGE BASE
How to Design a CRM or ERP Before Development
A CRM or ERP should begin with the real business process, not with the screen for creating a customer. The system must reflect how decisions are made, responsibility is transferred, documents are processed, and results are controlled.
Map the current process
Document where data comes from, who works with it, which statuses an object passes through, and what actions occur at each stage.
If the process currently lives in spreadsheets, messengers, and paper documents, describe exceptions and manual workarounds as well as the desired flow.
Define roles and permissions
Administrators, managers, executives, accountants, operators, and clients may use the same data but have different rights to view, edit, approve, export, or delete it.
Permissions should be modeled explicitly instead of being scattered as unrelated interface checks.
Design entities and data relationships
Identify the main business entities such as customer, company, deal, order, document, payment, task, inventory item, or another domain object.
Each entity needs relationships, lifecycle rules, history, and constraints that prevent the system from entering an invalid state.
Formalize workflow and automation
Automation should follow a defined workflow. A status change can create a task, document, webhook, notification, approval, or validation step.
Only automations that directly support the core operational process should be treated as MVP requirements.
Plan integrations and phased rollout
CRM and ERP systems often depend on accounting software, websites, email, telephony, payments, warehouses, or external directories.
For a large system, launching modules gradually is usually safer than switching the entire business to a new platform on one date.

Define the MVP, architecture, integrations, timeline, and budget before moving into production development.
