B2B Software Consulting in London
Serving the UK and European markets with deep expertise in cloud infrastructure migrations, secure multi-tenant SaaS architectures, and UK GDPR-aligned data systems.
Quick Answer
In short: ERPStack provides local custom ERP & B2B software engineering services in London, with high-availability AWS/Azure deployments optimized for local latency standards (< 20ms to UK endpoints, < 40ms EU average) and regional data compliance rules.
Regional Compliance
- UK GDPR
- Data Protection Act 2018
- FCA Regulations
Security & Compliance Architecture
London’s regulatory environment is one of the most stringent globally. A simple generic privacy policy is not enough; your infrastructure must be natively built for the Data Protection Act 2018 (UK GDPR) and, for financial firms, FCA (Financial Conduct Authority) regulations.
- Immutable Audit Logging (FCA Standard)We use Logtape integrated directly into the ORM middleware. Every `UPDATE` or `DELETE` mutation generates an encrypted cryptographic hash that is stored in an append-only log table. This provides a 1-click audit export for FCA compliance officers.
- UK GDPR Right to be Forgotten PipelineUnlike generic SaaS products where data is ghost-deleted, our architecture includes a programmatic `purgeTenant(id)` function that irreversibly wipes all related rows, AWS S3 buckets, and Redis cache fragments synchronously, generating a cryptographic certificate of deletion.
Engineering Blueprint
For our London-based deployments, we utilize an EU-West-2 localized architecture to ensure that zero data crosses sovereign borders. Our primary backend infrastructure leverages AWS London region edge nodes integrated tightly with Next.js Server Actions and Drizzle ORM.
Database & State Management
We bypass traditional monolithic data layers by implementing Schema-per-Tenant isolation in PostgreSQL. This means if you are running a B2B SaaS platform out of Canary Wharf, your clients’ data is physically separated at the database level, ensuring cross-contamination is mathematically impossible.
// Drizzle ORM Schema Isolation
export const tenantSchema = pgSchema('tenant_01');
export const users = tenantSchema.table('users', {
id: uuid('id').primaryKey().defaultRandom(),
email: varchar('email', { length: 256 }).unique(),
data_residency: varchar('data_residency').default('eu-west-2'),
});Evaluate Your Stack

Frequently Asked Questions
Yes, we architect solutions that are strictly deployed to UK-based data centers (e.g., AWS London eu-west-2 region) with localized RDS instances and database-level encryption to satisfy UK GDPR data residency rules.
Absolutely. A significant portion of our expertise lies in building high-performance, compliance-ready systems for the London financial sector, supporting real-time transaction processing and strict FCA audit logging.
Yes. We offer a Validation-First Pilot model where UK organizations only release milestone payments via PO after testing the architecture. We also provide Source Code Escrow under UK law to secure your IP.
We implement automated audit trail exporters formatted specifically for FCA compliance audits, detailing administrative read/write access logs in immutable PostgreSQL schemas using secure-by-default models.
We utilize localized AWS data centers in London (eu-west-2), ensuring all database schemas are physical segregated and zero patient/financial data leaves UK borders.
Yes, our architecture integrates Logtape directly into the Drizzle ORM layer, creating cryptographic, append-only audit records for all database transactions.
