Six production-shaped vertical SaaS products for Philippine SME workflows — laundry shops, carwashes, structural engineers, livestock trade, lending, and micro-business invoicing — all built through the saas-launch factory.
Sari-sari verticalis — six-product SME suite, cultivated 2026
Field notes
The context
Philippine neighborhood businesses — laundry shops, carwashes, small lenders, livestock traders, micro-businesses — run on paper stubs and memory. Each vertical needed a mobile-first, often Taglish, often offline-capable product that fits existing habits, built and verified fast enough for a one-person studio to ship six of them.
Cultivation
What I built
- Labada — mobile-first Taglish laundry-shop operations and public order tracking: fast intake, status tracking, public no-login links, rates, staff, shop settings, and admin operations, with tenant-isolated data through Supabase RLS; deployed and preparing for founder-assisted local launch.
- Kintab — carwash operating system across three deployed surfaces (landing, product PWA, Mission Control) with owner/staff/customer roles, shared schemas, three locales (English, Tagalog, Taglish), production Supabase, plus the complete physical and digital marketing suite (brand kit, business cards, flyers, brochure, social assets, promo video); preparing local launch.
- BaseShear — deployed NSCP structural-analysis and permit-report system: a pure TypeScript calculation engine, PHIVOLCS fault-trace and wind-zone data, RLS, offline behavior, tests, and a Chromium PDF service for permit-ready reports.
- Backten — deployed provincial livestock marketplace: PSGC geographic data, a provider-fallback LLM gateway, listings, semantic search, chat, KYC, manual payments, offline outbox, auctions, matching, and social features; retained as a secondary case study, not a market-validation claim.
- Kolekta — mobile lending and collection ledger: amortization engine, penalty accrual with parity between SQL and TypeScript, collector PWA and operator panel, RLS, property-based tests, and Playwright E2E.
- Resibo — localized, offline-capable AI-assisted quote, invoice, and receipt maker with Sentry, lifecycle and offline E2E suites, legal pages, and reproducible promo assets.
Root system
How it works
Every product shares the factory shape: pnpm + Turborepo monorepo, Next.js surfaces (landing, PWA, and an operations/Mission Control panel), Supabase Postgres with row-level security for tenant isolation, offline-first behavior where the vertical demands it, and Vitest + Playwright evidence gates before deploy. Domain-specific engines — NSCP calculations, amortization with SQL/TypeScript parity, the PSGC dataset — live as typed packages.
Harvest
Outcomes
- Six products taken to production shape by a single founder-engineer through the saas-launch system.
- Labada and Kintab deployed and preparing founder-assisted local launches with nearby Philippine businesses.
- BaseShear and Backten deployed as engineering case studies; correctness-heavy domains (structural analysis, money) shipped with deterministic engines and property-based tests.
- No customer adoption or revenue is claimed for any product before validation — a deliberate honesty constraint.
Vertical SaaS for local SMEs is won on workflow fit — Taglish copy, no-login tracking links, manual GCash billing — not feature volume. And in correctness-heavy domains, dual implementations with enforced parity (SQL vs TypeScript penalties) buy trust that tests alone don't.
