The common mistake: buying features instead of fixing workflows
Most ERP decisions start with a demo and end with a feature checklist. That approach fails because: what looks “complete” in demo often breaks in real operations — approvals, exceptions, partial deliveries, credit control, branch rules, and last-minute changes.
- Teams fall back to Excel/WhatsApp
- Controls are bypassed to “keep work moving”
- Data becomes unreliable, dashboards become irrelevant
When SaaS is the right choice
SaaS works well when your process is standard and your control requirements are moderate:
- Standard workflows: purchase → sales → basic inventory without heavy exceptions
- Low customization needs: you can adapt to the product’s process
- Fewer integrations: limited WhatsApp/email automation, simple accounting sync
- Single location: fewer branch/plant scope rules
- Short time-to-value: you want a quick start with minimal process redesign
When custom ERP is the safer long-term option
Custom ERP becomes necessary when your execution depends on controls and exceptions:
- Approval-driven organization: maker-checker, thresholds, escalations
- Complex dispatch/WIP: manufacturing stages, QC gates, partial dispatch
- Credit & receivables control: limit enforcement, holds, release rules
- Multiple branches/plants: scope-based access and reporting
- Heavy integrations: WhatsApp alerts, email triggers, API integrations, scanners, IoT (optional)
- Unique pricing/discount rules: role-based pricing, approvals, scheme logic
If your system needs role-based permissions + approvals to protect controls, read: Role-Based Permissions for ERP Adoption.
Decision framework: 6 questions leaders should ask
Use these questions to choose correctly:
- Workflow uniqueness: Can you fit into a standard flow without creating workarounds?
- Controls: Do you need maker-checker, thresholds, escalations, audit logs?
- Exception rate: How often do partials, rework, returns, credit holds happen?
- Integrations: Do operations need WhatsApp/email automation and API sync?
- Ownership: Can you define who owns what at each stage?
- Time horizon: Is this a 12-month tool or a 5-year operating system?
TCO reality: license cost vs operational cost
Leaders often compare: SaaS monthly cost vs custom one-time cost. The missing part is operational cost:
- Time wasted in manual chasing and reconciliations
- Errors from duplicate entry across tools
- Loss from uncontrolled discounts, credit leakage, or wrong dispatch
- Delayed decisions due to unreliable reporting
Implementation risk: where SaaS fails quietly
SaaS implementations fail not because the software is bad, but because:
- Approvals and exceptions are handled outside the system
- Permissions are too broad, so data quality drops
- Teams bypass steps to match real workflow
- MIS dashboards stop matching reality
A safer approach is module-wise rollout with controls: Module-Wise ERP Rollout Plan.
Hybrid approach (often the best option)
Many organizations succeed with a hybrid:
- Use SaaS for email, HR basics, simple accounting integrations
- Build custom ERP for execution-critical flows: production, approvals, dispatch, credit, WIP, analytics
- Connect both with APIs and automation
Checklist
- List your top 10 daily operational bottlenecks
- Identify control points (approval, QC, credit hold, cancellation)
- Estimate exception frequency (partials, returns, rework)
- Confirm integrations needed (WhatsApp, email, APIs)
- Decide horizon: 12 months tool vs 5 years operating system
