Based on Citrusbug’s 13 years of delivering custom supply chain management systems, building SCM software broadly costs anywhere between $30,000 and $500,000+. But that range alone means very little without context.

Unlike most software categories, SCM pricing is genuinely hard to estimate without knowing your stack. The number of modules, which ERPs you are connected to, whether AI forecasting is involved, and how many sites or users the system serves all pull the number in very different directions.

What we consistently see across projects is that integration work is the most underestimated line item. Teams budget for features but forget that connecting to SAP, Oracle, or a 3PL platform is a project within the project. The tiers below give you a more grounded starting point.

No two SCM projects land at the same number. Here is what actually drives the cost up or down, and by how much.

• Number of modules directly multiplies development effort, testing cycles, and delivery time.
• ERP integrations like SAP or Oracle can add $20,000 to $60,000 to project cost alone.
• AI and ML features such as demand forecasting require separate data pipelines and model training infrastructure.
• Multi-site or multi-tenant architecture requires more complex backend design from day one.
• Regulated supply chains in pharma or food require audit trails, serialization, and compliance-specific development.
• Real-time IoT or RFID integration adds sensor data processing and device connectivity overhead.
• Number of user roles and permission levels increases frontend and backend complexity significantly.
• Building greenfield costs less than modernizing a legacy ERP or WMS with existing data migration.
• Compressed delivery timelines require larger parallel teams, which increases the total engagement cost.
• Post-launch support and integration maintenance are recurring costs most initial budgets do not account for.
