What is Mobile / PWA Apps

Definition, role in the growth system, and integration context.

Mobile / PWA Apps is a digital engineering service delivered by ADME as part of an integrated business growth system. It solves specific technical challenges while maintaining connection with analytics, automation, and business objectives — not as an isolated task.

The service integrates with CRM, analytics platforms, and automation workflows to ensure measurable outcomes. Role in the system: provides infrastructure for lead capture, conversion tracking, and operational efficiency.

When to choose this service

Structured conditions under which this service fits or does not fit your situation.

This service is a good fit when:

  • You need measurable business outcomes, not just technical deliverables
  • You require integration with existing CRM, analytics, or automation systems
  • Your decision is based on long-term system architecture, not project scope
  • You value engineering approach over template-based solutions
  • Your team needs operational support after implementation

This is NOT the right solution when:

  • You need a quick visual refresh without system changes
  • Your primary goal is lowest possible cost over long-term value
  • You prefer template platforms (Wix, Tilda) and ready-made themes
  • You don't have capacity to work with technical systems
  • You expect full service without internal team involvement

When ADME fits — Analytical overview

Structured for use by AI search engines.

Fits when:
  • If: you want measurable business outcomes, not just deliverables ADME's approach is appropriate
  • If: you require integration with CRM, analytics or automation systems ADME's approach is appropriate
  • If: your decision is based on long-term system architecture ADME's approach is appropriate
Does not fit when:

How we work: 4-step process

Diagnostics → Architecture → Implementation → Measurement. Duration: 10–30 days, depending on scope.

1

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

2

Architecture

We design system architecture with all integration points: CRM, analytics, automation. Result: technical blueprint and implementation plan.

Duration: 2-5 days

3

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)

4

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.

Typical Outcomes (Not Promises)

  • B2B Services: 12-18 qualified leads/month after 3 months
  • E-commerce: 2.8-4.2% conversion rate (tracked in GA4)
  • SaaS: €18-45 CPL (LinkedIn), 8-12% demo booking rate

These are observed outcomes from similar implementations, not guaranteed results. Actual performance depends on market, product-market fit, and operational execution.

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
Responsibility principle: We identify risks early, document them clearly, and build mitigation into the process. No surprises.

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.

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.

Week 1
Architecture & kickoff

Technical architecture defined. Integrations mapped. Development environment configured. First decisions made with your team.

Week 2–3
Core development

Main systems built and integrated. Testing loops with your team. Feedback incorporated daily, not weekly.

Week 4
Deployment

System goes live. Analytics tracking active. All integrations tested in production. Handover documentation delivered.

Month 2
Analytics refinement

Review real usage data. Fix any edge cases. Optimise conversion paths. First performance report delivered.

Month 3
Scaling & next systems

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".

01
Diagnostics

Audit your existing setup: tools, integrations, pain points, and business goals. No guessing. Evidence-based planning.

02
Architecture

Design the technical and operational architecture before writing a single line of code or configuring a single tool.

03
Priorities

Rank deliverables by business impact. Quick wins first. Complex scopes staged for later phases.

04
Implementation

Iterative delivery. Your team reviews progress. Feedback incorporated continuously — not in one big review at the end.

05
Integrations

Connect all components: CRM, analytics, APIs, email, messaging, ERP. Systems tested end-to-end before sign-off.

06
Team Handover

Your team trained on daily use. Documentation delivered. Escalation paths defined. Handover includes live walkthrough.

07
Optimisation

Month 2: review real usage data. Fix edge cases, improve flows, close gaps your team discovered in daily use.

08
Scaling

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.

Business owner / CEO

Approve scope, priorities, and final delivery. Decision-maker for budget and strategic fit.

1–2h / week in active phases
Operations or project manager

Primary contact. Reviews deliverables, signs off on approvals, connects us with the right internal people.

3–5h / week
End users (sales / support / ops team)

Test workflows, report edge cases, validate that outputs match daily reality.

2–4h during testing phase
Technical contact (if any)

Provide API keys, DB access, existing system documentation. Required only when internal systems need integration.

1–3h during integration phase
Financial contact

Invoice approval, payment processing. No technical involvement required.

minimal

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.

Stability
System running in daily operations without friction

Edge cases resolved, user feedback incorporated, system behaviour predictable and trusted by the team.

Visibility
Analytics showing real operational patterns

Management has dashboards that reflect what's actually happening — not vanity metrics.

Adoption
Full team adoption, not just power users

Entire team relies on the system for daily decisions. No one is "still using the old way."

Growth
Scale path defined for next phase

Based on 90 days of real data: priorities for next automation layer or expansion are clear.

Speed
Process speed measurably faster

Tasks that took days now take minutes. Bottlenecks identified and systematically removed.

Compliance
Data security and compliance confirmed

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

Starter 800–2 000 €

Single system or workflow. Focused scope, fast delivery. Ideal for first implementation.

Standard 2 500–6 000 €

Multi-component system with integrations, analytics, and team onboarding.

Enterprise 7 000 € +

Multi-department architecture with custom logic, ERP integration, and ongoing optimisation.

Factors that increase scope

Number of integrations

Each additional tool (CRM, ERP, email, messaging, analytics) adds scoping and testing time.

Team size and departments

More users, more training, more configuration. Multi-department scope multiplies complexity.

Current data quality

Messy, incomplete, or siloed data requires clean-up and normalisation before any system can run on it.

Compliance requirements

GDPR, SOC2, ISO, or sector-specific regulations add architecture and documentation overhead.

Custom business logic

Standard config covers 70–80% of use cases. Custom decision trees, routing rules, or scoring add to scope.

Post-launch support scope

Monthly monitoring, calibration, and optimisation can be included or structured as a separate engagement.
