The product

Freelancers and self-employed professionals often run their finances across scattered tools — a notes app for expenses, a separate invoice template, no real visibility into tax liability until it's due. The Freelancer Finance Hub links income, invoicing, and tax estimation into one system instead of three disconnected templates.

Income & expense tracking Invoicing Tax estimation

The problem

Fragmented tracking across tools led to underpricing, missed deductible expenses, and tax surprises — the pieces existed, but nothing was connected.

Who it's for

Freelancers and small self-employed operators who need one source of truth for income, expenses, invoicing, and tax estimates, without paying for full accounting software.

What I scoped and why

01
Linked system

Connected income, expenses, and tax estimates so the tax figure updates automatically instead of requiring manual re-entry.

02
Anti-double-count rule

Built an explicit "Include in Revenue?" flag on the Invoice Tracker to prevent invoice payments being counted twice.

03
Estimates, not filing

Scoped to tax awareness and planning only — filing support would add jurisdiction-specific liability a template shouldn't carry.

04
Lightweight client records

Kept client & project records simple rather than a full CRM, matching a solo freelancer's actual scale.

Live dashboard tracking gross revenue, expenses, net profit, and estimated tax in one view
Invoice Tracker with automatic balance and days-remaining calculations per invoice
Tax Center estimating liability from real revenue, expenses, and deductible-expense flags
Next: multi-currency support built in from the start, for freelancers billing across currencies
