Building Wageasy
Wageasy is a mobile invoicing app for freelancers, consultants, and small shops — the people who'd rather be doing the work than chasing the paperwork around it. It's live and free on iOS and Android.
I kept watching freelancers I know run their entire billing operation out of three spreadsheets, a notes app, and a folder of half-finished invoice templates. Every payment chase meant digging through email to remember what was owed and by whom. The tools that fix this are either bloated accounting suites or subscriptions that cost more than the invoices are worth.
So I built Wageasy: one app that takes you from "project done" to "invoice sent" without the overhead. Clients, projects, and invoices in one place, and a PDF that looks like you meant it.
What it does
Invoices in seconds
Pick a client, add line items, export. Invoice numbers auto-increment, templates are yours to brand, and the PDF generates on-device so it's instant. The dashboard tracks what's paid, pending, and overdue, so you always know where the money actually is.
Clients and projects in one place
Every client carries their own invoice history and project details, so you stop hunting through email for the last thing you sent them. Mark clients active or inactive, link invoices to the project they belong to, and see the full relationship at a glance.
The details that matter in the field
- Multi-currency — 25+ currencies with auto-detection based on your location, for the international clients freelancers actually have.
- Offline PDF generation — invoices generate and share locally, no signal required.
- Push reminders — due dates and deadlines, so an overdue invoice doesn't sit forgotten.
- Data export — pull your invoice and client data out anytime, for accounting or backups. It's your data.
Security
Financial data isn't something to be casual about. Auth runs on Firebase, data is encrypted in transit, and everything sits in secure cloud storage. Standard practices, applied properly.
The stack
A few deliberate choices, because the boring parts are where invoicing apps usually rot.
Mobile — React Native + Expo. One codebase, iOS and Android. Expo's plugin ecosystem and build pipeline keep me shipping instead of fighting native tooling.
Marketing site — Astro 5 + Tailwind. The page you're reading. Static generation, TypeScript end to end, config-driven metadata, and a generated sitemap. Fast, and it ranks.
Auth — Firebase. Authentication and real-time sync across devices, so an invoice created on a phone shows up everywhere it should.
Database — self-hosted Postgres + Drizzle. Postgres because in years of running it, it has never been the thing that broke, and Drizzle for type-safe queries and migrations I can read.
Object storage — self-hosted S3 via RustFS. S3-compatible storage I run myself on Kubernetes — scalable, portable across any cloud, and no per-request surprise bill.
What's next
The roadmap leans into automation that removes data entry, not gimmicks:
- Invoicing assistant — formatting and pricing suggestions while you build an invoice, grounded in how you've billed before.
- Receipt-to-expense — photograph a receipt, get a categorized expense. No manual entry.
- Analytics — invoicing trends, revenue forecasts, and which clients actually pay on time.
- Time tracking — entries suggested from your work patterns instead of a running stopwatch you forget to stop.
Who it's for
Freelancers, consultants, agencies, and service providers — designers, developers, writers, contractors, anyone who sends invoices and would rather not spend an evening on it. Retainers, milestones, multi-client billing: it's built around how that work actually runs.
Where it's at
Wageasy is live and free, in early-adopter mode. I'm shipping against real feedback rather than a fixed feature list, so if you use it and something annoys you, that's the most useful thing you can tell me.
