Upkeep.pro — Service-Booking Marketplace at Scale
A dual-sided iOS, Android, and web marketplace connecting consumers with local beauty and home-service professionals. 500,000+ appointments booked daily, 10,000+ professionals worldwide, 37% proven income growth for providers — every number publicly verifiable on upkeep.pro.
The Opportunity
Local service businesses — barbers, hairstylists, nail technicians, makeup artists, house cleaners, landscapers — were stuck between two bad options. They could pay $50–$200/month for generic SaaS calendar tools that didn’t understand their booking flow, or they could keep running on phone-and-paper and lose customers to the competitor with a faster booking experience. Neither option drove new business; both added overhead.
Consumers wanted the opposite: a way to find a trusted local professional and book an appointment in under two minutes, with confidence the slot was confirmed and reminders would arrive automatically. The existing marketplaces felt like search engines — lots of profiles, very little instant booking. Upkeep.pro saw the gap: a dual-sided marketplace where the booking flow was the product, not an afterthought. They needed native iOS and Android apps for both sides plus a web platform — engineered to scale into hundreds of thousands of bookings a day without the friction creeping back in.
Project Scope
We engineered the full marketplace stack: two sides of the experience, three platforms, and the operational machinery underneath to support marketplace-scale traffic.
- Provider iOS + Android Apps: Business profile, availability management, booking inbox, instant accept/decline, client list management, automated reminders, business analytics dashboard, and 30-day free-trial onboarding flow.
- Consumer iOS + Android Apps: Sub-second professional search, verified-client review system, 1-to-2-minute booking flow with instant confirmation, in-app payments, push notifications for confirmations and reminders.
- Web Platform: Browser-based parity for users who prefer web, plus the marketing surface where most discovery happens. SEO-optimised provider profiles for organic search traffic.
- Real-Time Booking State Machine: Sturdy enough to survive marketplace-scale concurrency. Handles the booking lifecycle (request → confirm → remind → complete → review) with no ambiguous in-between states for either side.
- Provider Onboarding Pipeline: Client list import for migration from previous tools, 30-day free trial scoped to deliver first booking inside the trial period (the metric that determines conversion).
- Payment, Notification & Reminder Infrastructure: Stripe payment integration, APNs (iOS) + FCM (Android) push notifications with delivery confirmation, automated booking reminders for both sides.
Our Engineering Approach
Marketplace Velocity Discovery
Marketplaces succeed or fail at booking friction. We mapped both sides of the experience — consumer search-to-confirmation, provider request-to-accept — and engineered the system around minimising clicks, not maximising features.
Native-First Mobile Architecture
Native Swift for iOS, native Kotlin for Android — chosen for the deep platform integration that a daily-use marketplace app needs: smooth scrolling at scale, optimised search, native payment sheets, OS-level push notification reliability.
Real-Time Booking State Machine
The booking state machine is event-sourced and consistent across the consumer app, provider app, and web. No client device can show a different state than another. Eliminates the “did my booking confirm?” anxiety that kills marketplace trust.
Provider Onboarding Optimisation
The 30-day free trial is engineered for one outcome: get the provider to a successful first booking inside the trial. We designed the onboarding flow, the search-ranking boost for new providers, and the support touchpoints around that single conversion metric.
Push Notification Reliability
APNs for iOS and FCM for Android, with end-to-end delivery confirmation tracking. We verify the booking notification actually arrived on the device — not just that the server sent it. Critical for marketplace trust where a missed confirmation means a lost booking.
Challenges Solved
Sub-Second Professional Search at Scale
Provider search needs to feel instant — sub-second response — even as the marketplace scaled into the tens of thousands of providers. Solved with indexed search, query caching, and geo-bucketed result ranking.
Booking Confirmation Reliability
A booking that “maybe” confirmed kills marketplace trust faster than any other failure mode. Solved with the event-sourced state machine plus push-delivery confirmation tracking on both sides.
Provider Free-Trial Conversion
Providers who don’t get a first booking inside the free trial don’t convert. Solved with new-provider search-ranking boost, client-list import for migration, and proactive onboarding support around the first-booking milestone.
Business Impact
Every number below is publicly verifiable on upkeep.pro directly — we don’t self-report metrics for live client deployments.
500,000+ Daily Bookings
Half a million appointments confirmed every day through the platform — on iOS, Android, and web combined.
10,000+ Professionals
Service providers worldwide using the platform to manage availability, bookings, payments, and client relationships from a single mobile dashboard.
37% Income Growth
Upkeep.pro publicly reports a 37% proven income growth for providers using the platform — the metric that defines product-market fit for the provider side of the marketplace.
iOS + Android + Web
True cross-platform marketplace reach. Native mobile experience for daily-use providers and consumers; web for discovery, marketing, and browser-first users.
Public client tagline
“Made With You In Mind.”

Why This Case Study Matters
If you’re evaluating engineering partners for a service-booking marketplace, three things matter more than the pitch deck:
- Have they actually shipped a marketplace at scale? Most agencies build single-sided apps. Upkeep.pro is dual-sided (consumer + provider), three-platform (iOS, Android, web), and now serves 500K+ bookings daily. The architecture decisions that got us here — the booking state machine, the search infrastructure, the push delivery reliability — aren’t theoretical. They’ve been tested in production by 10,000+ professionals.
- Do they understand provider conversion? Marketplace economics live or die at provider activation. We engineered Upkeep’s 30-day free trial around one metric: first booking inside the trial window. That’s the difference between a marketplace that compounds and one that churns providers faster than it can recruit them.
- Will the apps survive year three? Marketplaces aren’t one-time builds. iOS and Android update every year, payment SDKs deprecate, App Store policy changes mean resubmission cycles. We’re still on Upkeep.pro through all of it. Read our mobile development services for the engagement model.
