InvoiceGen
Client and invoice records are local business files, not only remote SaaS database rows.
Local-first guide
What local-first invoicing means for freelancers.
Local-first invoicing means the important invoice workflow starts from files and software the user controls. InvoiceGen applies that idea to a native macOS invoice app and Rust CLI for private, repeatable invoice generation.
A CLI can create, list, render, export, and restore invoices without a hosted billing API.
PDF-ready invoice output and backup exports let users move data intentionally.
What is local-first invoicing?
Local-first invoicing is an approach where invoice records, client details, payment instructions, and invoice drafts are useful on the user's own machine first. A hosted service may still be useful for payment collection or accounting later, but the source invoice workflow does not disappear when an account is closed, a browser session expires, or a subscription changes.
For freelancers, consultants, and very small teams, this can be enough. They often need clean PDF invoices, predictable invoice numbers, project context, payment details, and a way to preserve records for taxes or client questions. They may not need a full accounting platform for every invoice.
Who is a local-first invoice generator for?
- Freelancers who invoice a few clients and want a private, focused workflow.
- Developers who want a scriptable invoice CLI instead of a browser-only form.
- Consultants who want client and project records without moving every detail into a cloud accounting suite.
- Small teams that prefer local backups and explicit exports before automation.
A practical local-first workflow
- Create or update clients and projects in the native Mac app.
- Add payment details, terms, line items, dates, taxes, and notes.
- Preview the invoice and export a PDF-ready document.
- Use the Rust CLI for repeatable listing, rendering, exporting, restoring, and agent workflows.
- Back up the local store before bulk changes or machine moves.
When a hosted tool may be better
Local-first does not mean every business should avoid hosted software. If a team needs multi-user approvals, cloud payment links, accounting-ledger sync, payroll, bank reconciliation, or accountant-managed workflows, a larger accounting suite may be the right tool. InvoiceGen is intentionally focused on private macOS invoice generation and scriptable local workflows.
