Most small businesses pay for QuickBooks, Calendly, HubSpot, Stripe, Notion, Google Workspace, ChatGPT Plus, and a half-dozen one-trick subscriptions every month — and still juggle five tabs to run a single client. We built BizLifeOS to prove a better path: a single custom iOS business operating system app, with Supabase auth, Stripe billing, full accounting, AI assistant, and 27 dedicated screens. Here is exactly how it is architected, why a client would commission one, and what we can build for your business.
The average small business owner pays for between eight and fifteen recurring SaaS subscriptions to run day-to-day operations. Most of those subscriptions overlap, none of them talk to each other natively, and the per-seat pricing scales fast as the team grows. The math gets bad quickly. A typical contractor or service business is paying $400–$900 a month in software fees long before payroll, and every tool requires a fresh login and a fresh learning curve.
A custom business OS iOS app collapses all of that into one place. Instead of paying nine vendors for nine fragmented experiences, your team opens one app, signs in with Face ID, and lands on a single dashboard that already knows the client, the project, the open invoice, and the next task. Every feature shares the same database, the same brand, and the same notification system. No integrations to break, no Zapier glue tape, no double data entry.
That is exactly the brief we set when we built BizLifeOS, and the result is a real production-grade iOS app with 27 production screens, a Supabase Postgres backend with row-level security, Stripe in-app subscriptions, a built-in AI assistant, MyBooks-style accounting, biometric auth, push notifications, an offline-first cache, and full data export. Below, we walk through how it is built — and how we can build the same kind of platform around your business.
Every custom business OS app we ship runs on a modern, battle-tested stack chosen for performance, App Store compatibility, and long-term maintainability. Nothing proprietary, nothing locked behind a no-code platform. You own every line of code at handoff.
React Native plus Expo gives us a single codebase that ships native to iOS and Android with the same performance feel as Swift, but at half the timeline. Supabase handles auth, the Postgres database with full row-level security, and the realtime sync layer. Stripe handles subscriptions and customer portals. Apple's expo-local-authentication wires Face ID and Touch ID directly into the login flow. Every secret — from API tokens to refresh keys — lives encrypted in expo-secure-store, never in plain AsyncStorage.
Why this stack: a TypeScript + Expo + Supabase pipeline lets us deliver in 6–14 weeks what a fully native Swift + custom backend build would take 9–18 months for. Performance is indistinguishable for 95% of business apps, and you keep the option to drop into native modules anytime.
BizLifeOS is not a single-feature mobile app — it is a true operating system for a business. Here is what is wired up in the production build, all sharing one Supabase database, one design system, and one auth context:
Daily briefing widget, quick actions sheet, AI floating button, and a customizable widget library so each user picks the cards they care about.
Full CRM with client profiles, project pipelines, custom fields, attachments via expo-document-picker, and Supabase realtime updates.
Branded PDF invoice generation, recurring schedules, proposal templates, and Stripe payment links sent direct from the app.
Bank statement PDF import with auto-categorization, subscription detection, year-round expense tracking, and CSV export for your CPA.
Profit-and-loss views, expense reports, payroll runs, and a tax-ready summary screen mapped to Schedule C deduction categories.
Live timer per project, manual entries, billable rate logic, and a one-tap pipeline from time entry to invoice line item.
Built-in calendar with project-linked events, plus a rich notes screen for meeting captures, voice memos, and idea storage.
Native AI chat backed by OpenAI or Anthropic, context-aware of your client list, invoices, and notes — ask "draft a follow-up email for Jacob" and it does.
Workflow builder for triggers like "new invoice paid" or "client created" with downstream actions like email, SMS, or status update.
Encrypted storage for client documents, contracts, and credentials — secured with biometric unlock and a hardware-backed key.
IMAP and SMTP integration so client conversations live next to their CRM record — no app-switching between Gmail and the CRM.
Tiered Stripe paywall with a feature-aware PaywallGate component that gracefully unlocks features as users upgrade.
Add Add-Ons, Login, Sign Up, Verify, Onboarding, Profile, Custom Settings, Settings, Expense Tracker, Payroll, Reports, Upgrade, AI Quick Response, and Daily Briefing — and you have a complete operating system in your pocket. Every screen shares the same theme context (with light/dark/system support) and the same offline-first cache so the app feels instant on every interaction.
Auth is where most low-end app developers cut corners. We don't. BizLifeOS is built on Supabase Auth with enforced row-level security policies on every table, biometric login via expo-local-authentication, hardware-backed secret storage via expo-secure-store, and an auditLog module that records every sensitive action with user and timestamp metadata. We also build in a rate limiter module to prevent brute force on critical endpoints.
// Row-level security policy on the finances table
create policy "users see only their finance rows"
on public.finances
for select
to authenticated
using (auth.uid() = user_id);
// Biometric unlock pattern in the login flow
const { success } = await LocalAuthentication.authenticateAsync({
promptMessage: 'Sign in to BizLifeOS',
fallbackLabel: 'Use passcode',
});
if (success) await restoreSession();When we hand off, you receive the full source, the Supabase project, the App Store Connect listing, the EAS build pipeline, and the Stripe integration. You own the data, the code, and the customer relationship. No vendor lock-in, no monthly platform tax, no proprietary scripting language. Move it to your own server tomorrow if you want.
Most custom business apps need a paywall — either to monetize directly (SaaS app sold to other businesses), or to gate premium features inside an internal tool. BizLifeOS ships with a complete tiered Stripe Billing integration: subscriptions, customer portal, webhook-driven access updates, and a reusable <PaywallGate> component that wraps any feature and gracefully prompts upgrade.
Free, Pro, and Business tiers with per-feature flags managed in Supabase — flip a flag, the paywall adapts in real time across all clients.
Stripe-hosted portal for plan changes, payment method updates, and invoice history — no support tickets to handle billing.
Supabase Edge Functions process Stripe events (subscription.created, invoice.paid, customer.deleted) and update entitlements instantly.
Every premium screen wraps in a PaywallGate component that checks tier and renders either the feature or a polished upgrade CTA.
There are three distinct profiles of buyer for a custom business OS iOS app:
1. The internal-tool buyer. A construction firm, real estate brokerage, or service business with 5–50 employees who has spent years duct-taping spreadsheets, QuickBooks, Trello, and email together. They want one app for their team, branded to their company, that pays for itself in cancelled subscriptions within 12 months.
2. The vertical-SaaS founder. Someone who knows a niche — HVAC, plumbing, photography, fitness coaching — and wants to launch a category-defining app for that vertical. We deliver the full platform, App Store listing, Stripe billing, and AI assistant in 8–14 weeks. They focus on selling. We handle the product.
3. The high-net-worth solo operator. A consultant, agency owner, or trades operator clearing $300K–$2M solo who wants their entire business to live on their phone, in their brand. The economic value is not the cancelled subscriptions — it is the time savings and mental clarity from running everything in one tool that respects how they work.
BizLifeOS as a portfolio piece: we built BizLifeOS specifically because we wanted to prove we could ship a multi-tenant, paywalled, AI-enabled iOS business OS as a single solo team. If you can describe a business workflow, we can build the app that runs it.
Every project is scoped, but here is the menu of capabilities we bring to a custom business OS iOS app build:
One Expo + React Native codebase shipping native apps to the Apple App Store and Google Play. Single team, single budget.
Postgres database, realtime sync, edge functions, and bulletproof row-level security policies on every table.
Face ID, Touch ID, and passcode fallback wired into the auth flow with secure refresh-token storage.
Tiered billing, customer portal, webhook entitlement sync, and a reusable in-app paywall component.
Context-aware chat using OpenAI or Anthropic, fed live data from your CRM, calendar, and finance tables.
Expo push setup with deep links, segmented audiences, and Supabase trigger-based send logic.
SQLite-backed offline-first store with background sync — the app stays usable on a job site or a plane.
EAS Build pipeline, App Store Connect setup, screenshots, listing copy, and TestFlight distribution to your beta team.
