Ask three vendors to quote "enterprise custom software" and you'll get numbers ranging from $50,000 to $500,000+ for what sounds like the same project on paper. Here's what actually drives that spread, so you can tell whether a quote is realistic or a lowball that grows later.
What Actually Drives Enterprise Cost
Integration count and depth. A system that stands alone costs a fraction of one that needs to integrate deeply with existing ERP, CRM, identity/SSO, and data warehouse systems. Each integration is its own scoped piece of work, and enterprise environments routinely need several.
Compliance requirements. HIPAA, SOC 2, or CCPA-aligned architecture adds real engineering time — audit logging, data handling controls, access management — that's easy to underscope in an initial quote if the vendor hasn't built compliant systems before.
Data migration complexity. Moving from a legacy system is often more expensive than building the new system itself, particularly when the legacy data is inconsistent, undocumented, or spread across multiple sources that need reconciliation.
Team seniority and structure. A team of senior engineers costs more per hour but often costs less overall — fewer bugs, less rework, faster decisions on ambiguous requirements. A cheap hourly rate with a junior-heavy team frequently costs more by the time a project actually ships.
Realistic Price Bands
- $25,000–$75,000 — a focused enterprise tool or internal system with limited integrations and standard compliance needs
- $75,000–$200,000 — a system with multiple deep integrations, meaningful compliance requirements (HIPAA/SOC 2), or AI components requiring custom evaluation infrastructure
- $200,000+ — enterprise platforms with extensive legacy data migration, multiple compliance regimes, or ongoing multi-team development rather than a single build
How to Tell a Realistic Quote From a Lowball
A quote significantly below this range for genuinely enterprise-scope work usually means one of three things: the vendor hasn't fully understood your integration and compliance requirements yet (expect the number to grow), the team is junior and inexperienced with enterprise constraints, or scope will quietly shrink once development starts. Ask specifically how the quote accounts for the integrations and compliance requirements above — a vendor who can answer in detail is more trustworthy than one who gives a round number fast.
Fixed-Price vs Time & Materials for Enterprise Work
Fixed-price works when requirements are genuinely well-understood upfront. Enterprise systems rarely stay that well-defined once real users interact with early versions, which is why time & materials or a dedicated-team model fits most enterprise custom software better — see our pricing model comparison for the tradeoffs in more detail.
