What kills engineering velocity
We stand against the standard agency practices that drain budgets and produce rigid, bloated systems.
- Exorbitant and compounding user seat license costs
- Forcing operational workflows to adapt to generic database schemas
- Failing security reviews due to retrofitted compliance controls
- Data hostage locks and proprietary API call limitations
- Fragile, undocumented legacy monolith technical debt
- Waiting months for standard upstream feature releases
Engineering you can audit
- SOC 2 ✓
DevSecOps & Threat Modeling
We integrate Arcjet web application firewalls, Semgrep SAST static analysis, and automated OWASP ZAP penetration tests directly into your GitHub Actions CI/CD pipelines. Security is enforced on every single pull request, not left to annual third-party audits.
- SOC 2 ✓HIPAA ✓
Built-In SOC 2 & HIPAA Controls
Regulatory requirements are codified directly in your database schemas and service layers from commit one. We implement Row-Level Security (RLS) policies, AES-256 column encryption, and FHIR v4 API integrations to ensure you pass procurement audits instantly.
Strict Type-Safe Integrity
We enforce 100% concrete types with zero 'any' casts across the full stack. Our data validation pipelines utilize Zod schemas to guarantee boundary safety, with more than 80% unit, integration, and E2E (Playwright) test coverage verified in CI before deployment.
Multi-Region Cloud (IaC)
We build resilient, active-active configurations utilizing Terraform to automate deployments across AWS and Azure VPC enclaves. Our systems incorporate PgBouncer pooling, global Edge middleware routing, and automated multi-region failover structures.
Source Code Escrow Contracts
We protect your operational continuity with independent software escrow agreements. If we ever fail to support you, the complete, buildable source code, documentation, and IaC scripts are legally released from escrow custody directly to your engineering team.
Bespoke Database Schema Mapping
We never force your operational model into rigid SaaS standard fields. Your data structures are designed to match your exact business logic using native relational entities, ensuring optimal query optimization and indexing under high transactional volume.

Our engineering methodology
- 1
Architecture Discovery
We begin with a deep-dive audit to design your flexible blueprint. This small upfront commitment maps your exact system requirements.
- 2
Technical Blueprinting & Prototyping
We engineer the initial pilot or MVP using our proprietary Proprietary Core and deploy it to a secure staging environment for your review.
- 3
Client Validation
Your team tests the architecture. We don't ask for milestone payments until you validate that the software meets the agreed performance criteria.

Frequently Asked Questions
What is custom ERP development?
Custom ERP development is the process of designing and building a tailored Enterprise Resource Planning system specifically for your company's workflows. Unlike off-the-shelf SaaS, custom ERP systems give you complete control, full source code ownership, and eliminate recurring per-seat user licensing fees.
How much does custom ERP development cost?
Custom ERP development with ERPStack ranges from $25,000 to $250,000, depending on the complexity, modules, and third-party integrations. We work on a transparent, fixed-price milestone model with no hidden fees or seat licensing.
How long does it take to build a custom ERP system?
Typical delivery times range from 8 to 20 weeks. Our team deploys a working foundation within the first three weeks, followed by bi-weekly releases of operational modules so your team can test and integrate vertical slices iteratively.
What is the difference between custom ERP and SaaS?
SaaS ERP products charge continuous per-seat monthly license fees, lock your data in proprietary formats, and require expensive workarounds for custom processes. ERPStack custom ERPs are developed for a one-time fixed price, deploy directly to your cloud infrastructure, and give you 100% IP ownership.
Does our company own the source code and IP?
Yes. Upon final milestone approval and payment, 100% of the intellectual property rights and full production source code are transferred to your company. There are zero ongoing licensing costs, royalties, or vendor lock-in.
