  2. 2Create folders by month or category (Office, Travel, Meals, etc.)
  3. 3Note the business purpose on the back or in the file name
  4. 4Back up to cloud storage (Google Drive, Dropbox, iCloud)

The 5-Minute Weekly Routine

Set a recurring 5-minute appointment every Sunday. Here's what to do:

1Review bank/card transactions from the week1 min
2Categorize any uncategorized expenses2 min

Common Tracking Mistakes to Avoid

  • Mixing personal and business - Makes it nearly impossible to track accurately
