Systems that fit how your organisation actually works
Most large organisations run on a mix of ageing core systems, packaged software bent out of shape, and spreadsheets filling the gaps between them. We build the custom systems and integrations that close those gaps (internal tools, back-office platforms, multi-tenant products) and modernise the legacy pieces without a big-bang rewrite.
- Legacy modernisation using the strangler pattern, not a risky rewrite
- Integration with your ERP, CRM, HR and finance systems
- Role-based access, audit trails and compliance designed in from the start
Who this is for
Organisations whose processes have outgrown the software that was meant to run them.
Established businesses with legacy systems
A core system built years ago still runs the business. It works, but the people who understand it are leaving, changes take months, and nothing new can talk to it.
Operations teams running on spreadsheets
Approvals, reconciliations and reporting happen in Excel and email because the packaged software does not fit the process. Errors are found late and nobody is sure which version is current.
Companies launching a SaaS product
You are turning an internal system or a proven service into a multi-tenant product and need tenancy, billing, permissions and data isolation done correctly the first time.
Enterprise software services
These are the engagements we take on most often. Larger programmes usually combine modernisation with integration and a set of internal tools.
Legacy modernisation
Replacing an ageing system piece by piece using the strangler pattern: new capabilities are built alongside the old one, traffic is routed over one function at a time, and the legacy code is retired once nothing depends on it. It applies when the system is too important to switch off and too costly to keep as it is.
- Codebase and dependency assessment
- Domain-by-domain migration plan
- Anti-corruption layers between old and new
- Parallel running and phased retirement
Systems integration
Connecting the software you already run (ERP, CRM, HR, payroll, finance, warehouse) so data is entered once and flows where it is needed. It applies whenever teams re-key between systems or reports disagree because each system holds its own version of the truth.
- SAP, Oracle, Dynamics, Salesforce and HubSpot connectors
- API gateways and event-driven messaging
- Master data and reference data alignment
- Error handling, retries and reconciliation
Internal tools & back-office systems
Purpose-built applications for the processes packaged software handles badly: approvals, case management, procurement, scheduling, reporting. It applies when the workaround has become a spreadsheet nobody dares to change.
- Workflow and approval engines
- Admin panels and operational dashboards
- Document generation and e-signature
- Bulk import, export and scheduled jobs
Multi-tenant SaaS platforms
Turning an internal system or a proven service into a product other organisations pay to use. Tenancy model, data isolation, billing, plan limits and self-service onboarding are decided at the architecture stage, because they are expensive to retrofit.
- Tenant isolation strategy: shared schema, schema-per-tenant or database-per-tenant
- Subscription billing and plan enforcement
- Tenant-level configuration and branding
- Usage metering and rate limits
Access control, audit trails & compliance
Role- and attribute-based permissions, single sign-on with your identity provider, and immutable logs of who changed what and when. It applies to any system that regulators, auditors or your own risk team will ask questions about.
- RBAC and ABAC with SSO (SAML, OIDC, Active Directory)
- Tamper-evident audit logging
- Data retention and deletion policies
- Controls mapped to SOC 2, GDPR, HIPAA or local requirements
Data migration
Moving records from the old system to the new one without losing, duplicating or silently altering them. It applies to every modernisation and most integrations, and it is the part most likely to slip if it is treated as an afterthought.
- Source profiling and data quality report
- Mapping, transformation and cleansing rules
- Rehearsal migrations with reconciliation counts
- Cutover plan and rollback
Also part of the engagement
Technologies & platforms
Dedicated project management
A named project manager, a written plan, weekly reporting and a single point of contact for the duration.
Security review
Threat modelling during design, dependency scanning in the pipeline and a code review pass before anything handles production data.
Documentation & handover
Architecture decision records, runbooks and admin guides written for the people who will run the system after we leave.
Support & maintenance
Retainer or per-incident support once the system is live, including upgrades to frameworks and dependencies.
How we approach enterprise work
You own the software
Source code, infrastructure and documentation sit in your accounts and repositories from the first commit. No licence fees, no lock-in to us.
Change in increments
We do not do big-bang rewrites. Each phase delivers something that runs in production and can be measured, and the plan is adjusted from what we learn.
Built for the audit
Permissions, logging and data handling are designed in at the start rather than bolted on when the auditor arrives.
What the engagement looks like
- 01
Discovery & assessment
We map your systems, data flows and manual workarounds, review the legacy codebase where there is one, and agree what the first phase should be.
- 02
Architecture & plan
A written architecture, integration inventory, migration sequence and phased plan with a cost range for each phase.
- 03
Build in phases
Delivered in increments that go to production; integrations and migrations tested against real data with reconciliation before cutover.
- 04
Handover & support
Documentation, training for your administrators and engineers, and a support arrangement that suits how you operate.
What you receive at the end
Everything runs in accounts you control from the first commit. Ending an engagement is an access change, not a migration.
- Source code in your repository
- Architecture and decision records
- Integration and API documentation
- Data migration reconciliation reports
- Runbooks and administrator guides
- Handover and training sessions
We’ve got the answers you seek
Anything not covered here? Ask us through the contact form and we’ll answer within a working day.
We use the strangler pattern: the new system is built alongside the old one and takes over one function at a time, with an anti-corruption layer keeping the two in step. The legacy system stays live until nothing depends on it. It takes longer than a rewrite looks on paper, but it is the approach that reliably reaches production.
