What Custom Software
Actually Costs
By Project Type
Most custom software quotes come back as a wide range. Here are real numbers broken down by type — at $30 per hour, with the US agency equivalent for comparison.
(1) Development cost — one-time, paid to the agency. (2) Infrastructure and maintenance — ongoing, paid monthly.

Simple Internal Tool — $6,000 to $15,000
CRUD applications, operations dashboards, basic workflow tools, simple data management portals.
At $6K-$10K: single user type, one core workflow, standard CRUD.
At $10K-$15K: multiple user roles, basic reporting, one integration.
Timeline: 6 to 14 weeks. Good for: replacing spreadsheets and manual processes.

Complex Enterprise System — $50,000 to $150,000
ERP replacements, multi-location management platforms, regulated industry software.
Drivers of complexity: compliance requirements (SOC 2, HIPAA, GDPR controls), complex data models, high availability requirements, advanced audit logging.

What Makes Custom Software More or Less Expensive
What increases cost
Complex business logic
Unique rules, edge cases, non-standard workflows.
Number of integrations
Each third-party API adds $2K-$8K.
User role complexity
RBAC with many permission levels adds $5K-$15K.
Compliance
HIPAA, SOC 2, GDPR-specific controls each add $8K-$20K.
Real-time features
WebSockets, live dashboards add infrastructure complexity.
Unclear requirements
Scope changes mid-project add 20-40% to cost.
What reduces cost
Buy don't build
Clerk for auth ($0/mo), Stripe for billing (0.5%), Resend for email ($20/mo).
MVP scope discipline
Launch with one workflow, add features after user feedback.
Complete brief
Vague briefs produce expensive scope changes.
Phased delivery
Phase 1 MVP, Phase 2 funded by Phase 1 revenue.
Standard tech stack
Next.js + PostgreSQL is faster than bespoke choices.
What Custom Software Costs After Launch
The development bill is one-time. The monthly cost of running custom software is ongoing — and it is the number most founders forget to budget for.
