# Custom ERP, CRM & B2B Software Development Services

ERPStack designs and builds custom B2B systems — ERP platforms, CRM systems, headless content
architectures, cloud migrations, headless eCommerce, and security and compliance platforms — on
Next.js, TypeScript and PostgreSQL. Every engagement is priced as fixed-fee milestones, deploys
into your own AWS or Microsoft Azure account, and transfers 100% of the source code at handover.
There are no per-seat licences.

### Custom ERP Software Development Services

We design and build complete, custom resource planning (ERP) systems that consolidate your business operations. Our systems integrate your supply chain, financials, human resources, and warehousing into a single, high-performance platform. Deployed directly to your AWS or Azure infrastructure, you retain 100% ownership of the code, database, and intellectual property. Say goodbye to restrictive per-seat licensing and build a system that adapts to your unique processes.

### Headless Payload CMS Content Architectures

We engineer headless content management architectures designed to distribute digital experiences at global scale.

### Cloud Migration & Resilient Infrastructure Consulting

Rescale your legacy applications with resilient, cloud-native architectures. We containerize monoliths using Docker and Kubernetes, automate deployments with CI/CD, and define your infrastructure using Terraform. Our multi-region, high-availability deployments ensure maximum uptime, automatic failover, and compliance audit readiness. We straggle legacy systems progressively to prevent downtime and operational disruption during migration.

### Security & Regulatory Compliance Services

## Commercial model

- Fixed-fee milestones, quoted after a discovery phase. No hourly billing.
- Zero per-seat licensing: unlimited users and client portals at flat hosting cost.
- 100% source-code and intellectual property transfer at handover, including infrastructure-as-code.
- Deployment into your own AWS, Microsoft Azure, or Google Cloud account.

## Compliance posture

ERPStack holds no SOC 2 report, ISO 27001 certificate, PCI DSS attestation, HIPAA certification,
or FedRAMP authorisation, and none of these transfer from a supplier to a buyer. Systems are
engineered against those control baselines — server-side RBAC, AES-256 at rest, TLS 1.3 in
transit, append-only audit logging — and documented so the assessor you appoint can test them.
