Context

**FreshBooks** — Invoicing, expenses, time tracking, payments, and accounting for small businesses. It currently costs $23/mo.

For freelancers, invoices, time tracking, and expense logs are buildable; payments, tax/accounting reports, bank feeds, client portal, and reliability make it more than trivial.

This brief describes a focused, single-operator replacement for the part of FreshBooks that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Generate invoices, track clients/projects/time, record payments/expenses, export reports, and email PDFs.

Model a narrow bookkeeping workflow with explicit review and export steps.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Database.

Invoice PDF generation.

Email service.

Stripe/PayPal optional.

Backups.

Simple reporting.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build me a freelancer invoicing app to replace FreshBooks. Requirements:

A local web app: Node + Express + better-sqlite3, binds to localhost.

Tables: clients, projects, time entries, expenses, invoices, payments.

Invoices get sequential numbers (INV-2026-001).

Time tracking: a start/stop timer per project plus manual entries;

uninvoiced time rolls into the next invoice draft at the project's hourly

rate.

Invoice PDFs: an HTML template rendered with Puppeteer, my logo and bank

details from config.json, saved to ./invoices/INV-XXXX.pdf.

Send an invoice by email via SMTP creds in .env, BCC me; mark paid manually,

with an overdue list on the home page.

Expenses: amount, category, optional client, receipt image attached.

Reports: income by month, unpaid invoices with aging, income by client, and

a yearly totals CSV export for my accountant.

No accounts, no telemetry, all data local; nightly copy of the SQLite file

to ./backups/, keep 30.

Out of scope: card payments and a client portal, clients get a PDF and pay

by bank transfer. Skip bank feeds and double-entry accounting.

README: setup, SMTP config, and how to edit the invoice template.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Payment collection.

Bank imports.

Accounting reports.

Client portal.

Compliance, licensing, and legal accountability are core features.

Connectors, OAuth flows, and vendor API changes require constant upkeep.

What you still own after launch

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Maintain every third-party integration as APIs and OAuth rules change.

Risk

**High consequence.** Use this as a prototype or personal aid. Keep a qualified human and an established provider in the loop for consequential decisions.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.
