What ERPStack builds
ERPStack engineers custom ERP systems and B2B software for healthcare, FinTech, logistics and retail organizations. Each system is built on Next.js, TypeScript and PostgreSQL, deployed into your own AWS or Microsoft Azure account, and handed over with the full source code. No per-seat licence, no vendor lock-in.
Free — No Commitment

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.
- 4
Payment & IP Transfer
Once validated, you approve the Purchase Order. We transfer 100% of the IP, source code, and deploy it to your cloud infrastructure.

Frequently Asked Questions
Quick answer
In short: ERPStack engineers custom ERP and B2B software systems on Next.js, TypeScript and PostgreSQL for healthcare, FinTech, logistics and retail organizations. Every engagement is fixed-price, deploys into your own AWS or Microsoft Azure account, and transfers 100% of the source code on completion. Zero vendor lock-in, no per-seat licence: you own your code.
What is custom ERP development?
Custom ERP development is the engineering of an Enterprise Resource Planning system around one company's workflows rather than a vendor's template. Unlike off-the-shelf SaaS, custom ERP systems give you complete control of the data model, full source code ownership, and no recurring per-seat licence fee. It is the right choice when your process is the competitive advantage and configuring around a packaged product would flatten it.
How much does custom ERP development cost?
Custom ERP systems from ERPStack range from $25,000 to $250,000, depending on module count, integration surface and data migration scope. We work on a transparent, fixed-price milestone model with no hidden fees and no seat licensing. For comparison, renting a proprietary ERP for 50 users costs about $233,200 over 3 years at $99 per user per month, the anchor our ROI calculator uses. Software you own carries no such recurring line.
How long does it take to build a custom ERP system?
Typical delivery runs 8 to 20 weeks. The engineering team deploys a working foundation inside the first 3 weeks, then ships operational modules on a bi-weekly cadence so your staff test vertical slices as they land rather than at the end. Timeline is driven by integration count and data migration far more than by module count: a system with 2 clean APIs moves faster than one with 6 legacy exports.
What is the difference between custom ERP and SaaS ERP?
SaaS ERP charges a continuous per-seat licence, holds your data in a proprietary schema, and needs paid workarounds when a process does not fit the template. A custom ERP from ERPStack is a one-time fixed-price software engineering build, deploys to your own cloud account, and transfers 100% of the intellectual property. The trade is capital cost now against a licence line that never ends, and in our model the crossover arrives inside year one.
Does our company own the source code and IP?
Yes. On final milestone approval and payment, 100% of the intellectual property and the full production source code transfer to your company, including the Terraform infrastructure definitions and CI pipelines. The custom ERP systems ERPStack builds carry no ongoing licence cost, royalty or vendor lock-in, and need no proprietary runtime to run. Source code escrow is available where procurement needs the transfer guaranteed in writing before delivery.
