How we work: 4-step process
Diagnostics → Architecture → Implementation → Measurement. Duration: 10–30 days, depending on scope.
Diagnostics
We analyze your current systems, business goals, and technical constraints. Result: clear understanding of what needs to be built and why.
Duration: 1-3 days
Architecture
We design system architecture with all integration points: CRM, analytics, automation. Result: technical blueprint and implementation plan.
Duration: 2-5 days
Implementation
We build the system, integrate all components, test conversion tracking and operational workflows. Result: working system ready for launch.
Duration: 7-21 days (depends on scope)
Measurement
We monitor performance, track key metrics, provide operational support and optimization recommendations. Result: data-driven improvements.
Duration: 30 days post-launch (included)
This is not bureaucracy — it's an experience signal showing methodical approach and risk reduction.

What Can Go Wrong & How We Mitigate It
Mitigation:
- System audit during diagnostics phase (before commitment)
- API compatibility testing in staging environment
- Fallback to manual workflows if automated integration blocked
- Clear documentation of dependencies before architecture phase
Mitigation:
- Dependencies list agreed upfront with clear ownership
- Weekly sync calls for decision alignment (not status updates)
- Placeholder content/data if client materials delayed
- Phased launch: MVP first, refinements in 30-day support period
Mitigation:
- Baseline metrics established during diagnostics (realistic targets)
- Measurement framework active from day 1 (not post-launch)
- 30-day optimization included: adjust based on real data
- Honest attribution: distinguish system impact from market factors
Mitigation:
- Technical documentation: architecture diagrams, workflow guides
- Live walkthrough during handoff (recorded for reference)
- 30 days operational support via Telegram/email
- Ongoing retainer option for teams without technical capacity
A PWA (Progressive Web App) runs in the browser, installs on the phone screen, works offline and receives push notifications. No app stores, no SDK, no Apple Review process. Ideal for business tasks: client portals, booking systems, field worker apps, quick forms and checklists. Mobile-first React / Vue + API + CRM.

Quick decision guide
You probably need this if…
Recognise 3 or more? Let's talk.
- The current solution is slower, more expensive, or more fragile than it should be
- You've outgrown spreadsheets or legacy tools and know something has to change
- You're losing revenue or time to a problem that should have been solved already
- You've thought about fixing this for 6+ months but haven't found the right partner
- Your team has informal workarounds that only work because of specific people
- You've tried a template or off-the-shelf product and it doesn't fit your process
What happens after we launch
We do not deliver and disappear. Here is exactly what the first 90 days look like.
Technical architecture defined. Integrations mapped. Development environment configured. First decisions made with your team.
Main systems built and integrated. Testing loops with your team. Feedback incorporated daily, not weekly.
System goes live. Analytics tracking active. All integrations tested in production. Handover documentation delivered.
Review real usage data. Fix any edge cases. Optimise conversion paths. First performance report delivered.
Based on what's working: plan next phase of integrations, automation, or content expansion.
How a project is structured from day one
Every engagement follows a defined operational structure. No surprises, no black boxes, no "we'll figure it out".
Audit your existing setup: tools, integrations, pain points, and business goals. No guessing. Evidence-based planning.
Design the technical and operational architecture before writing a single line of code or configuring a single tool.
Rank deliverables by business impact. Quick wins first. Complex scopes staged for later phases.
Iterative delivery. Your team reviews progress. Feedback incorporated continuously — not in one big review at the end.
Connect all components: CRM, analytics, APIs, email, messaging, ERP. Systems tested end-to-end before sign-off.
Your team trained on daily use. Documentation delivered. Escalation paths defined. Handover includes live walkthrough.
Month 2: review real usage data. Fix edge cases, improve flows, close gaps your team discovered in daily use.
Expand on stable foundations. Add automation layers, new integrations, and AI capabilities as your operations grow.
Who is involved from your side
You don't need a dedicated technical team. Here's what each role actually contributes — and how much time it takes.
Approve scope, priorities, and final delivery. Decision-maker for budget and strategic fit.
Primary contact. Reviews deliverables, signs off on approvals, connects us with the right internal people.
Test workflows, report edge cases, validate that outputs match daily reality.
Provide API keys, DB access, existing system documentation. Required only when internal systems need integration.
Invoice approval, payment processing. No technical involvement required.
What stabilises in months 3–6
Most implementations deliver their real ROI not at launch week — but when the system is running smoothly in daily operations. Here's what you typically see.
Edge cases resolved, user feedback incorporated, system behaviour predictable and trusted by the team.
Management has dashboards that reflect what's actually happening — not vanity metrics.
Entire team relies on the system for daily decisions. No one is "still using the old way."
Based on 90 days of real data: priorities for next automation layer or expansion are clear.
Tasks that took days now take minutes. Bottlenecks identified and systematically removed.
All integrations audited. Data flows documented. Access controls reviewed. Compliance documentation available.
What affects project scope and cost
We don't quote from a price list. Every project is scoped based on your specific systems, team size, and integration complexity. Here's what moves the number.
Typical project ranges
Single system or workflow. Focused scope, fast delivery. Ideal for first implementation.
Multi-component system with integrations, analytics, and team onboarding.
Multi-department architecture with custom logic, ERP integration, and ongoing optimisation.
Factors that increase scope
Each additional tool (CRM, ERP, email, messaging, analytics) adds scoping and testing time.
More users, more training, more configuration. Multi-department scope multiplies complexity.
Messy, incomplete, or siloed data requires clean-up and normalisation before any system can run on it.
GDPR, SOC2, ISO, or sector-specific regulations add architecture and documentation overhead.
Standard config covers 70–80% of use cases. Custom decision trees, routing rules, or scoring add to scope.
Monthly monitoring, calibration, and optimisation can be included or structured as a separate engagement.
