Step‑by‑step: Setting up your log viewer

1. Create the master sheet – Open a new Google Sheet and label columns: Date, Platform/Client, Gross Income, Payment Method, Expense Tags, Net Income, Notes.

2. Add a drop‑down for expense categories – Use Data > Data validation to include common write‑offs such as Vehicle, Home Office, Supplies, Software, Meals (50 %).

3. Link a quarterly tax calculator – Insert the formula =SUMIF(Date, ">="&DATE(YEAR(TODAY()),1,1), Net Income)*0.153 to estimate SECA tax for the year; adjust the multiplier to 0.0765 for the employer‑half deduction.

4. Automate app payouts – Export CSVs from rideshare or freelance platforms (Uber, Upwork, Fiverr) weekly and paste them into the sheet. Use =ARRAYFORMULA(VLOOKUP(...)) to auto‑populate expense tags based on payer.

5. Reconcile monthly – At month‑end, compare the sheet’s total gross income with your bank statements and 1099‑NEC forms. Highlight mismatches in red for quick follow‑up.

6. Backup & export – Every Friday, copy the sheet to a dated folder in Google Drive and export a CSV for your accountant.
