How we build on-demand software
Discovery & operations mapping
We map how customers, providers and money actually move — booking, dispatch, payment and payout — and turn that into a scoped roadmap.
UX/UI design in Figma
Every role — customer, provider or driver, dispatch, admin — gets its screens designed and reviewed in Figma before engineering starts.
Architecture & build
We build the shared backend — the booking and order model, dispatch and payments — first, then the customer, provider and admin surfaces on top, so every screen reads one source of truth.
QA automation & CI/CD
Critical flows are covered by Playwright end-to-end tests that gate every merge, with automated deployments to staging and production.
Launch & support
We handle iOS/Android store submission and cloud deployment, then stay on for iteration, monitoring and new features.
Systems and tools we integrate
We build against the payment, maps and messaging services an on-demand platform actually runs — as documented, API-first integrations. Card payments run through Stripe, which handles PCI compliance, so card data never touches our clients’ servers.
Ways to work with us
End-to-end build
We scope, design, build and ship the whole platform — customer and provider apps, admin and backend — then support it. The model behind ServiPR, Just Dry Cleans and Bix.

On-Demand software: questions we get asked
Home and local services marketplaces, ride-hailing and courier apps, on-demand laundry and delivery, salon and grooming booking, and gig-economy platforms — spanning customer and provider apps on iOS and Android, web, and admin dashboards. The laundry how-to is /blog/how-to-build-an-on-demand-laundry-app.
Yes. We typically build every surface on one backend: a customer app, a provider or driver app, and an admin panel. On ServiPR that was a customer app, a provider app and a web back office; on Just Dry Cleans and Bix it was customer, agent or driver, and admin.
We integrate Stripe for card payments, with Apple Pay and Google Pay at checkout, and Stripe Connect to split earnings and pay providers out. Stripe handles PCI compliance, so sensitive card data never touches our clients’ servers.
Every job runs on one backend model that all surfaces read from, with a real-time layer — typically Firebase — pushing each status and location change out, so the customer, provider and admin views never disagree.
Yes. We build the full two-sided workflow — provider onboarding and verification, instant or scheduled booking, in-app chat, ratings, and dispute handling — as delivered on ServiPR and our other marketplace builds.
Both. We build end to end (as with ServiPR, Just Dry Cleans and Bix), embed engineers in your team, or provide a dedicated cross-functional team.
