Plinth

Year zero

The boring middle, made obvious.

Real records, fast actions, no dashboards-of-dashboards. Plinth is a calm invoicing surface where clients, invoices, and quarterly totals live in one scan.

A clean and bright home office desk with a laptop, books, and plants, perfect for freelancers or remote work.

Product

Three surfaces, no bloat.

Plinth gives you clients, invoices, and a quarterly summary. Each one does exactly one job.

Client directory

Every client lives in one searchable table. Click to see their invoice history, total billed, and contact details — no folder digging.

Invoice tracking

Create invoices with a number, amount, and due date. Move them from draft to sent to paid with one click in the edit modal.

Quarterly stats

A horizontal bar shows outstanding vs. paid totals for the current quarter. Numbers update as you mark invoices.

How it works

Capture, review, act.

01

Capture

Create a client record with name, email, and company. Then issue their first invoice in seconds — just a number, amount, and due date. No fields you don't need.

02

Review

Scan the ledger. Status pills tell you without recounting what's draft, sent, paid, or overdue. Filter by status or search by client name to focus on what needs attention.

03

Act

Update an invoice status, edit a client record, or remove outdated entries, all from modal dialogs that keep you in context. The quarterly stats update automatically.

Context

Built for real work.

Plinth is the kind of tool you open during a client call, not something you visit once a quarter. The interface stays out of your way.

Early feedback

What people are saying.

“I was tracking invoices in a Google Sheet with color-coded tabs. Plinth replaced the whole thing in ten minutes. The status filter alone saved me an hour a week.”

“The demo data sealed it. Instead of staring at blank screens, I had a working dashboard thirty seconds after signing up. Changed the names, kept the workflow.”
