The client approached My Digital Solutions – The Global Tech Hub® with a clear ambition:
Transition from operating as a traditional cleaning company to becoming a structured UK cleaning marketplace.
The goal was not simply to build a booking website.
The goal was to:
• Redesign the acquisition model
• Remove commission dependency
• Create predictable revenue streams
• Introduce operational tools for traders
• Build an investor-scalable marketplace infrastructure
The Strategic Challenge
Most service marketplaces fail for three reasons:
Poor unit economics
Weak booking structure
Lack of operational tooling for providers
In the UK cleaning sector, common friction points include:
• Lead-buying fatigue
• High admin burden
• Informal booking processes
• Unverified reviews
• Poor repeat booking retention
The challenge was to design a platform that solved both sides of the market simultaneously.
Our Strategic Approach
Rather than building “another listing directory”, we architected:
A structured, fixed-fee marketplace with embedded SaaS functionality.
The model was designed around:
• Transparent fixed contributions (no commission)
• Repeat booking monetisation
• Tier-based visibility incentives
• Cluster-first geographic rollout
• Built-in compliance and review integrity

Results & Positioning Impact
The platform is live, operational, and structured for phased expansion.
More importantly, it now stands as a demonstrable proof of capability for:
My Digital Solutions – The Global Tech Hub®
as a serious marketplace and SaaS development partner.

Let Us Help You Build a Brand That Lasts
Technology Architecture
Frontend: React + Vite
Backend: Node.js + Express + TypeScript
Database: PostgreSQL
Payments: Stripe (idempotent webhooks + ledger tracking)
Messaging: Twilio integration
Mobile: Expo-managed application
Built for:

Commercial Model Engineering
We helped structure the revenue model around:
• £5 customer booking confirmation
• £2 trader repeat contribution
• Optional subscription tiers (£0–£49.99)
• SMS credit wallet system
No percentage commission.
This creates predictable acquisition economics and protects provider margins — a major differentiator in the UK services marketplace landscape.
Why This Case Study Matters
Scrub Squad UK® demonstrates what happens when a marketplace is engineered with commercial logic, not just design aesthetics.
It showcases:
• Marketplace architecture
• Billing logic design
• SaaS integration
• Unit-economics thinking
• Operational scalability
• Regional rollout modelling
This is the level of thinking required for serious platform builds.
Frequently Asked Questions
What is a two-sided marketplace platform?
A two-sided marketplace platform connects two distinct user groups — typically service providers and customers — within a structured digital environment.
Unlike a simple directory, a true marketplace manages:
• Discovery
• Structured booking or transaction flow
• Communication
• Monetisation logic
• Review integrity
• Governance controls
When built correctly, it becomes an operational ecosystem rather than just a listing website.
How much does it cost to build a marketplace platform in the UK?
Marketplace development costs vary depending on:
• Booking lifecycle complexity
• Payment integrations
• Compliance requirements
• SaaS functionality (CRM, invoicing, dashboards)
• Admin governance controls
A properly engineered MVP marketplace in the UK typically requires structured planning before development begins. Attempting to build without commercial clarity often leads to expensive rebuilds.
At My Digital Solutions – The Global Tech Hub®, we design the monetisation model and commercial logic before a single line of code is written.
How long does it take to build a marketplace MVP?
A structured MVP marketplace typically takes 12–20 weeks depending on scope.
However, timeline is influenced by:
• Payment and billing architecture
• Role-based access control
• Admin enforcement systems
• Compliance modules
• Regional rollout mechanics
Speed without structure creates instability. We prioritise scalable foundations.
What is the biggest mistake founders make when building marketplaces?
The most common failure is focusing on features instead of economics.
A marketplace must answer:
• How does supply get incentivised?
• How does demand convert reliably?
• What are the unit economics?
• What prevents disintermediation?
• How is repeat behaviour monetised?
Technology cannot fix weak commercial architecture.
Should I choose a commission model or fixed-fee model?
Commission models are common because they are simple to explain.
However, they can:
• Discourage high-value providers
• Compress provider margins
• Reduce long-term loyalty
Fixed-fee or hybrid contribution models can offer:
• Predictable acquisition costs
• Transparent economics
• Stronger provider retention
• Cleaner investor narratives
The correct model depends on sector dynamics and transaction frequency.
What features are essential in a scalable marketplace?
Core structural components include:
• Role-based access control
• Structured booking lifecycle states
• Audit-ready billing logic
• Transparent contribution enforcement
• Verified review system
• Geographic density control
• Repeat monetisation mechanics
Without these, scale becomes fragile.
How do you prevent providers and customers from bypassing the platform?
Disintermediation is a common marketplace risk.
It can be mitigated through:
• Structured booking value
• CRM retention tools
• Contribution incentives
• Review gating mechanisms
• Communication centralisation
• Transparent billing design
The platform must create ongoing value beyond the first transaction.
Is it better to scale nationally from day one?
In most cases, no.
Regional density first creates:
• Higher match rates
• Stronger retention
• Better operational stability
• Lower churn
Cluster-based rollout reduces liquidity risk.
What makes a marketplace investor-ready?
Investors assess:
• Unit economics clarity
• Contribution logic
• Billing enforcement
• Governance control
• Provider retention mechanics
• Market density strategy
Technical polish alone is not enough.
A marketplace must demonstrate structured economic design.
Can an existing service business transition into a marketplace?
Yes — but it requires clear separation between:
• Service delivery
• Platform infrastructure
• Revenue model
• Brand positioning
Operational transformation must be structured carefully to avoid market confusion.
