It Carries Real Load
Thousands of concurrent users, millions of transactions and a Monday-morning peak that does not care about your architecture diagram. Capacity, caching and failover are design decisions, not tuning done after launch.
Codazz is an enterprise software development company delivering enterprise application development services to US organisations — custom enterprise software development, system integration and legacy modernisation, built by 200+ developers under SOC 2 Type II and ISO 27001 controls.

An enterprise software development company builds custom applications that carry organisation-wide load — thousands of concurrent users, decade-long service life, deep integration and formal audit requirements. Codazz delivers enterprise application development, integration architecture and legacy modernisation under SOC 2 Type II and ISO 27001 controls.
Thousands of concurrent users, millions of transactions and a Monday-morning peak that does not care about your architecture diagram. Capacity, caching and failover are design decisions, not tuning done after launch.
Enterprise systems outlast the team that built them. Documented architecture decisions, automated test coverage and boring, conventional technology choices are what let the next team maintain it.
SOC 2, ISO 27001, HIPAA, GDPR and PCI-DSS require evidence, not intentions. Access control, audit logging and data classification have to be engineered in — retrofitting them after a finding costs multiples.
Enterprise applications live inside a landscape of ERP, CRM, HRIS, warehouses and one system nobody wants to touch. Integration architecture is usually more than half the real work.
Organisations where a line-of-business process runs on spreadsheets and tribal knowledge, and the cost of that is now measurable.
A critical application on unsupported technology, with a shrinking pool of people who understand it and a rewrite that keeps getting deferred.
Healthcare, financial services, insurance and public sector, where compliance evidence is a delivery requirement rather than a later concern.
A dozen systems, no source of truth, and reconciliation work that consumes an entire team every month.
A capable internal team with more roadmap than headcount, needing squads that work inside their SDLC rather than around it.
Data residency requirements, multi-currency and multi-entity structures, and rollouts that have to phase by region.

Your repos, your cloud
Most agencies are structured to ship a product and move on. Enterprise software is not that job. It has to survive an audit, absorb a decade of changing requirements, integrate with systems that predate the cloud, and stay up while a business runs on it. That means SSO and granular RBAC from day one, immutable audit logging, documented architecture decisions, security review gates in CI, disaster recovery that has actually been tested, and a support model with an SLA behind it. Codazz runs 200+ developers under SOC 2 Type II and ISO 27001 controls because enterprise buyers require exactly that — and because it is the only way software this long-lived stays maintainable.
Custom enterprise application development, integration architecture, legacy modernisation, enterprise ERP and CRM platforms, and the cloud and security engineering underneath all of it.
Line-of-business platforms, workflow engines, portals and internal tools built for thousands of users with SSO, RBAC and audit trails from day one.
API layers and event-driven architecture that break the silos between ERP, CRM, HRIS, warehouse and legacy systems — with monitoring and SLAs.
Retire unsupported systems incrementally with the strangler pattern — old and new running in parallel with reconciliation until each slice is proven.
Custom ERP and platform implementation covering finance, inventory, purchasing and production for multi-entity organisations.
Custom CRM platforms and enterprise implementations with complex permission models, CPQ and data warehouse feeds.
Cloud migration, HA/DR architecture, infrastructure as code and compliance engineering for SOC 2, ISO 27001, HIPAA and GDPR.
Every enterprise software development engagement is scoped, priced and staffed the same way — so these hold on every project, not just the showcase ones.
SOC 2 Type II and ISO 27001 certified delivery. Encryption, least-privilege access, immutable audit logging, dependency scanning and an auditor evidence pack are part of the build, not a later remediation project.
Architects, backend, frontend, QA and DevOps in-house across US-overlapping time zones. Scale a programme up for a rollout phase and back down afterwards without carrying the headcount.
We sequence delivery so a usable slice reaches production early and the rest builds on validated foundations. Modernisation uses the strangler pattern so the business keeps running throughout.
Code in your repositories, infrastructure in your cloud accounts, architecture decisions and runbooks handed over. No proprietary framework in the middle and no dependency on us to keep it running.
One process, five stages, fixed milestones. You always know what is happening and what it costs.
We map the business problem, the users and the constraints, then agree what success looks like in numbers.
Flows, interface design and a clickable prototype, so the hard decisions are settled before engineering starts.
Two-week sprints against a fixed scope. You see working software every fortnight, not a status report.
Load testing, security review, migration and a rollout plan — with someone from the build team on call.
Monitoring, iteration and a support SLA. Most clients keep building with us long after go-live.
Pick junior, mid and senior engineers and compare monthly and total cost ranges by region against US/Canada.
We do not just build products — we engineer intelligent, connected, future-proof digital experiences.

Best-in-class tools chosen for performance, reliability, and long-term maintainability.
The difference between an enterprise software development firm and a capable agency shows up in year three, not month three. These are the things worth verifying before you sign.
Ask for the SOC 2 Type II report and ISO 27001 certificate, not a claim on a website. Enterprise procurement will ask for them eventually — better to know now.
Ask to see ADRs from a real project. A firm that cannot show you documented decisions is leaving your next team to reverse-engineer intent from code.
Ask how many developers they employ versus subcontract. Enterprise programmes need architects, QA and DevOps on tap — we run 200+ in-house for exactly this reason.
If the proposal has one go-live date eighteen months out, the risk is entirely yours. Demand a sequence where usable slices reach production each quarter.
A partner that insists on owning the whole thing is protecting a lock-in position. Good firms work inside your SDLC and hand over cleanly.
Ask for response and resolution SLAs, the on-call rotation and the incident process in writing. Reactive per-incident billing is not a support model.

Ask our teamCost is driven by user scale, the number of systems in the integration scope, the depth of compliance work and how many regions the rollout covers. A single line-of-business application sits at one end of the range, and an organisation-wide programme running several parallel squads at the other. Every engagement is scoped fixed-price per phase or as capped time-and-materials after a free architecture review, so the number is agreed against a written specification before delivery begins.
Load, longevity and governance. Enterprise systems carry thousands of concurrent users, live for a decade, integrate with a dozen other systems and get audited. That requires SSO and granular RBAC from day one, immutable audit trails, tested HA and disaster recovery, documented architecture decisions, security review gates and a support model with SLAs behind it. Codazz runs 200+ developers under SOC 2 Type II and ISO 27001 controls precisely because enterprise buyers require it.
A single well-scoped enterprise application takes four to six months to first production release. Platform programmes covering several business processes run nine to eighteen months, phased so value lands each quarter rather than at the end. We always sequence delivery so a usable slice reaches production early and the rest builds on validated foundations.
Yes — most enterprise engagements are co-delivery. We embed squads inside your SDLC, using your repositories, ceremonies, code review standards and security policy, and staff whatever the actual gap is: architects, backend, frontend, QA, DevOps or all of it. With 200+ developers we can scale a team up for a rollout phase and back down afterwards.
Compliance is engineered in rather than audited on afterwards. We design to your control framework — SOC 2, ISO 27001, HIPAA, GDPR, PCI-DSS — with encryption at rest and in transit, least-privilege access, immutable audit logging, data classification and residency controls, secrets management and dependency scanning in CI. Penetration testing and an auditor evidence pack are delivery items, and NDAs and DPAs are signed on day one.
Yes, and we strongly prefer not to do big-bang rewrites. We put an API facade in front of the legacy system, then move capabilities behind it one at a time using the strangler pattern, running old and new in parallel with reconciliation until each slice is proven. The business keeps operating throughout, and a misbehaving slice rolls back on its own rather than taking the programme with it.
Yes. Managed support runs against agreed response and resolution SLAs with an on-call rotation, monitoring and a defined incident process, plus a funded enhancement backlog and quarterly roadmap reviews. Support is priced as a retainer scaled to your criticality tier rather than billed reactively per incident.
You do, without exception. Code lands in your repositories, infrastructure in your cloud accounts, and architecture decision records, runbooks and test suites are handed over as deliverables. There is no proprietary framework of ours in the middle and no dependency on us to keep the system running.
Always, on day one and before any project discussion. Enterprise discovery requires access to real processes and often real data, so the NDA and, where personal data is involved, the DPA come first as a matter of course.
