The challenge

What needed to change.

Leslie manages a commercial property and pays about 90% of its expenses on an American Express card. Every month, around 20 charges had to be sorted into the P&L spreadsheet by hand. With limited time, keeping the books current was getting pushed aside.

What we did

The work inside the file.

  1. 01

    Took the monthly AmEx statement export and separated real expenses from the card payment, which isn’t an expense.

  2. 02

    Matched each charge to the right P&L category, following how earlier months had been coded.

  3. 03

    Combined multiple charges from the same vendor, including hardware store purchases, into a single line using the same format as previous months.

  4. 04

    Caught an item already entered on the sheet, so it wasn’t counted twice.

  5. 05

    Flagged one unfamiliar vendor for the client to confirm, leaving a note in the cell instead of guessing silently.

  6. 06

    Updated only the new month’s column, leaving existing formulas, formatting and hidden columns unchanged.
