Mid-market companies grow unevenly: new locations, products, employees, sometimes new business models. ERP has to reflect that growth without triggering a major project every time.

Typical requirements:

• Process fit: industry-specific workflows instead of compromises forced by standard software
• Process-oriented start: core processes first, extensions when the need arises (extending process-oriented ERP)
• Integration: connecting accounting systems, e-invoicing, machines, document management, and inventory systems
• Cost planning: per-user license costs scale with growth. Open source and fixed operating models change the calculation
• Independence: avoiding vendor lock-in, keeping providers and hosting interchangeable

Off-the-shelf standard ERP promises speed but often fails on edge cases: project business, batch tracking, serial production, or customer-specific approvals. Individual ERP platforms address this through customization at the metadata and low-code level.

For the decision: clarify scope and ROI before the big project. A 48h prototype or a structured requirements specification creates a solid basis before budget and timeline are fixed.

ERP in mid-market companies is not an IT topic alone. Executive leadership sets priorities, business units contribute processes, and IT ensures operation and integration. ERP fundamentals provide the shared framework.
