Overview

Mowa Books is the first product in the Mowa product family. Built for freelancers, builders, and small businesses that need clean books for compliance and decision-making, without learning accounting in the process.

What it does

The user records what actually happened (sent an invoice, ran payroll, paid a supplier) and the bookkeeping follows from those actions. Multi-business books with per-currency accounts in NGN, USD, GBP, and EUR. PDF invoicing with payment tracking. Payroll with automatic tax calculation. Project-level instalment tracking with CSV import. Categorised transactions, account-scoped reports, and CSV export per report tab. Local backup and restore, with cloud sync arriving as a paid tier.

How it was built

Mowa Books is a local-first web application. Data lives in the browser via Dexie / IndexedDB, with cloud sync slated as a paid tier. The full Next.js 16 application runs on Cloudflare Workers via @opennextjs/cloudflare, which keeps the deployment unified with the rest of the Mowa stack. Authentication runs on Clerk. The payroll tax engine is built in pure functions, fully unit-tested, so payroll calculations stay reliable as the codebase evolves.
