Simple Invoice

Invoicing software splits into two camps: a full accounting platform with a subscription and a learning curve, or a spreadsheet and a PDF export. Simple Invoice was built for the gap between them — issue the invoice, take the payment, give the client somewhere to look it up.

It runs on React with Supabase behind it, Stripe for payment, PDF generation for the document itself, and a client portal so the recipient does not need an account with the sender's accounting software just to see what they owe.

How it came together.

The work moves from the right question to a system the team can actually use.

1. 01

   Strategy

   It starts with a strategy session — I come to you, learn the business inside out, and shape a plan you actually want and that actually works. Goals first, never template-first.

2. 02

   Design

   Then I design it — interface, brand and the feel of using it — mapped straight to that strategy. One person, one vision, no handoff gap between designer and developer.

3. 03

   Development

   I build the real thing: fast, typed end-to-end, Supabase-backed, and yours outright — the website and the operations behind it, shipped on a tight loop.

4. 04

   Iteration

   We iterate on the live product — real usage, real numbers — tightening the funnel and the workflows until it genuinely performs.

5. 05

   Ongoing management

   From there I keep it running and growing — performance, updates, new campaigns and features as the business moves. One number to call, no agency runaround.
