Custom ERP Software Pricing: What to Expect from Development to Deployment

Custom ERP software pricing in 2026 demands strategic planning, especially for Indian SMEs navigating GST complexities, NSE volatility, and niche workflows that off-the-shelf solutions like SAP or Odoo simply can’t accommodate without endless add-ons. Ahmedabad entrepreneurs scaling affiliate marketing empires or Gujarat manufacturers chasing Make-in-India targets face upfront investments from ₹80 lakhs to ₹5 crores, but reap 35-45% TCO savings over five years through perfect-fit automation syncing Twilio Conversations, Semrush data, and real-time inventory.

Pricing Models: Fixed, Time & Materials, or Hybrid?

Fixed Price (SME Favorite): ₹1.2-3.5 crores locked via milestones—perfect for defined scopes like “GST-compliant inventory + Twilio CRM for 100 users.” Pros: Predictable budgeting. Cons: Changes cost ₹8-25 lakhs extra/module. 70% of my clients choose fixed for MVP launches.

Time & Materials (T&M): ₹700-1,800/hour Ahmedabad rates (vs ₹2,500+ Mumbai). Ideal for evolving fintech NSE feeds or construction RA billing. Flexible but needs tight PM control—budget overruns hit 25% without.

Hybrid Gold Standard: ₹75 lakhs fixed MVP + T&M expansions. My FMCG distributor client started fixed (inventory core), added T&M geo-DMS—total ₹2.1 crores, 16-month ROI.

2026 Twist: Low-code platforms (Retool, Bubble) slash MVP 25-35%, but lock scalability.
