# Profit margins at a glance — categorized income & expense (Quillenhart qaduu clone)

Clone of [faisalmq/3cpo](https://dev.to/faisalmq/freelance-finance-tracker-google-sheets-3cpo) buyer channel + Quillenhart Gumroad **"Income & expense tracking, fully categorized"** and **"Auto-calculated net profit for any month you select"** ($15, 7 ratings).

## The problem faisalmq names

Without a clear view of profit margins, you make pricing decisions on guesswork. Are you actually profitable on that long-term project, or are overhead costs eating the margin? [faisalmq/3cpo](https://dev.to/faisalmq/freelance-finance-tracker-google-sheets-3cpo) sells three outcomes:

1. **Automated summaries** — profit margins at a glance
2. **Tax preparedness** — expenses categorized before filing season
3. **Centralized data** — one log, not emails + bank statements

Quillenhart's Transactions tab is the same promise: log once, categorized, net profit recalculates per month.

## Why Google Sheets / CSV beats enterprise software

[faisalmq/3cpo](https://dev.to/faisalmq/freelance-finance-tracker-google-sheets-3cpo): no accounting degree, no bloated subscription. Quillenhart: **shaded cells only** — you type in the log, margins calculate themselves.
