Use cases

Where clients put us to work first.

Regulated SaaS

Audit-ready client platforms

Multi-tenant portals for firms whose customers run security questionnaires — access logs and evidence generated by design.

Ops automation

Back-office that runs itself

Invoicing, reporting, reconciliation, and follow-ups automated end to end, with monitoring so failures surface before customers notice.

AI intake

Lead capture & qualification

Voice and chat agents that engage enquiries 24/7, qualify them, and book the meeting — escalating to a human only when it matters.

Knowledge

Query your own documents

Turn internal docs and SOPs into an assistant your team can ask, with citations and access control.

Fractional CAIO

AI leadership on tap

A roadmap for where AI creates leverage — and where it doesn't — plus the governance to roll it out safely.

Migration

Inherit a system cleanly

Take over an undocumented codebase: we produce the decision trail, threat model, and runbook so your team owns it, not fears it.

Why we exist

Most software engagements fail quietly.

Engineered to be inherited.

Not at launch — but eighteen months later, when the original team is gone, nothing is documented, the codebase resists change, and a security review surfaces problems nobody can trace to a decision.

FlowState IT was built to make that outcome impossible. Every material decision is recorded and auditable. Risk transfers to us during delivery. And you own an asset your next CTO can inherit without archaeology.

We've engineered production systems for regulated and high-stakes environments long enough to know that “high quality” isn't a standard — because it can't be audited. So we build to standards that can: OWASP ASVS L2, infrastructure as code, immutable audit trails, and a governance pack most agencies never produce.

How we deliver

Four stages. You are never locked in.

Each stage has defined outputs, written acceptance criteria, and an exit point.

Stage 0Fixed fee · 2–3 weeks · credited against the build

Discovery & Technical Audit

Before we quote a build we do the work to quote it honestly: system architecture proposal, a threat model for your domain, a compliance gap analysis, a phase-level roadmap, and a fixed-price Stage 1 proposal. Complete enough for any supplier to execute — our proposal wins on merit, not hostage-taking.

Stage 1+2–4 week phases · invoiced per phase

Phased Build

The build is decomposed into phases with written acceptance criteria agreed before each begins. You approve each phase before the next starts, with continuous access to staging, the repository, and a weekly written status report of work, risks, and decisions.

WarrantyCritical: 4 business hours · Major: 2 business days

90 Days Post-Launch

Any defect against the agreed acceptance criteria found within 90 days of launch is fixed at no cost, with severity-based response commitments written into the contract — not offered as goodwill.

RetainerMonthly · scoped to your risk profile

Continuity (optional)

Post-warranty cover for dependency and vulnerability patching, threat-intelligence response, monitoring and incident triage, and a defined allocation of enhancement hours. Unmaintained systems become liabilities; the retainer exists so yours never does.

The engineering standard

“High quality” isn’t a standard. This is.

Commitments your technical advisers can verify — line by line.

Architecture

Fully modular, domain-separated, multi-tenant by design where applicable, with documented tenant isolation. Every module independently updatable and testable.

Security baseline

OWASP ASVS Level 2 verification standard across the application. Secure defaults, least-privilege access throughout.

Access control

Role-based access control with audit logging on every privileged action. Immutable audit trail suitable for compliance evidence.

Vulnerability mgmt

Automated SAST, DAST, and dependency scanning in CI. Continuous CVE and threat-intelligence monitoring, with patching under warranty and retainer.

Infrastructure

Infrastructure as code. Your entire environment is reproducible from the repository, reviewed like application code — no undocumented manual config.

Resilience

Defined and tested RPO and RTO. Automated backups with restoration rehearsed before launch, not assumed.

Observability

Structured logging, metrics, error tracking, and alerting from day one. You know before your customers do.

Quality gates

Automated tests with agreed coverage thresholds on business-critical paths. No phase passes acceptance without green pipelines.

The governance pack

Own an asset, not just a codebase.

The documentation layer most agencies never produce.

Architecture Decision Record

Every material technical decision, the alternatives considered, and the reasoning. “Why was it built this way” has a written answer.

Threat Model

Structured analysis of your attack surface, the threats relevant to your data and users, and the controls against each. Updated every major phase.

Security Posture Document

Plain-English statement of controls mapped to recognised standards — ready for customer security questionnaires, insurers, and auditors.

Operational Runbook

Deployment, environment config, incident response, escalation paths, and recovery procedures. Your ops don't depend on anyone's memory, including ours.

Forensic Handover

A full decision trail at completion: every choice, every reversal and why, the environment contract, known risks, and open items with owners. Any team can pick it up cold.

The Production-Grade SaaS Buyer's Checklist

The 30-point checklist we use to audit whether a software build will survive its first security review and its next CTO. Score your current or planned system in ten minutes.

Get the checklist
  • The 8 governance documents any inheritable system must ship with
  • The security baseline that turns audits into a formality
  • The 5 contract clauses that move delivery risk off your desk
  • A red-flag list for spotting a supplier who's building you a liability

Compliance-ready by default

Compliance-ready by default

If your customers are enterprises, government bodies, or regulated firms, your software will be audited whether you plan for it or not. We build so the audit is a formality.

  • Compliance evidence generated as a byproduct of how the system is engineered — access records, change history, audit logs, tested backups, vendor risk docs.
  • SOC 2 and ISO 27001 readiness is a configuration of what already exists, not a retrofit project.
  • AI systems designed against the EU AI Act for the relevant risk tier from the first line of code — documentation, logging, and human-oversight controls included.
  • EU AI Act compliance runs as a dedicated practice area, embedded in every build, not sold separately.

Why teams choose us

Engineered to be inherited

We document completely because we're confident in the delivery. Any competent team can take the system over cold.

Every commitment is contractual

The standard, the warranty, the IP assignment, the response times — written into the contract, not aspirational.

Risk transfers to us

Fixed-fee discovery, per-phase acceptance, and a 90-day warranty mean the delivery risk is ours to carry.

UK-based & supported

Real people, UK hours, no offshore black box.

Engagement structure & investment

Fixed-fee discovery. Fixed-price phases. £50k–£150k.

Discovery is a fixed fee agreed up front and credited against the build on proceed. Build phases are fixed-price against their acceptance criteria, invoiced on acceptance. Typical production SaaS engagements run £50,000–£150,000 depending on scope, integrations, and compliance depth — discovery exists so the number we give you is one we'll stand behind.

Questions

Straight answers.

How do I know what it will cost?+

Discovery is a fixed-fee audit (2–3 weeks) that produces a fixed-price build proposal before you commit. The discovery fee is credited against the build if you proceed.

What if we want to stop partway?+

You can stop at any phase boundary. Every phase ends in a working, documented, owned increment, and you're invoiced per phase — never locked into the next by the last.

Who owns the code and documentation?+

You do. Full IP assignment on payment: code, infrastructure-as-code, test suites, and the complete governance pack.

Are you compliance-ready?+

Yes. SOC 2 and ISO 27001 readiness is a configuration of what we already build. AI systems are engineered against the EU AI Act for the relevant risk tier from day one.

What happens after launch?+

A 90-day warranty fixes any defect against the acceptance criteria at no cost, with contractual response times. An optional continuity retainer covers patching, monitoring, and threat response after that.
