# Frequently asked questions about ERPStack

Everything you need to know about building custom B2B software with ERPStack — from costs and timelines to compliance and post-delivery support.

## Category Quick Answer / TL;DR

### What is the pricing model and timeline for custom ERP development?

Custom ERP projects cost between $25,000 and $250,000 using a fixed-cost milestone model with zero licensing fees. Complete implementation takes 6 to 24 weeks with real working software delivered in bi-weekly sprints.

### What technology stack and architecture patterns does ERPStack use?

We build headless ERP systems using Next.js, TypeScript, PostgreSQL, and Drizzle ORM. We integrate legacy systems via the Strangler Fig pattern for a zero-downtime, progressive migration path.

### Does ERPStack support regulatory compliance standards like SOC2, HIPAA, and GDPR?

Yes. We build systems with built-in controls engineered to meet SOC 2 Type II, HIPAA (including FHIR v4 APIs), and GDPR requirements, featuring data encryption at rest, secure VPC networks, and immutable audit logs.

### How does ERPStack migrate data from legacy platforms like SAP or NetSuite?

Migrations typically take 8 to 12 weeks. We extract data via APIs or Change Data Capture (CDC), map it to PostgreSQL schemas, and run parallel runs to validate all records before cutover.

### Why choose custom ERP over SAP, NetSuite, or Dynamics 365?

Custom ERP provides 100% intellectual property ownership, zero recurring seat licenses, and fits your exact business workflows without sandbox or code limitations, saving mid-market teams thousands annually.

### What is the development methodology and source code ownership model at ERPStack?

We operate in bi-weekly agile sprints with an initial 1–2 week Discovery phase. Clients retain 100% source code ownership from day one, with optional maintenance and SLA retainers available post-launch.
