Steps
Plan three sheets before you touch Excel: an input invoice sheet, a tracker log sheet, and a summary dashboard sheet. Keep them in that order so formulas flow one way.
Install the Claude add-in for Excel from the add-ins menu and sign in with your Claude account. Confirm the Claude pane appears on the right side of the workbook.
Open the Claude pane and prompt it to build the invoice sheet. List your columns, such as invoice number, client, date, description, quantity, rate, line total and grand total.
Enter a test invoice and check that line totals multiply quantity by rate and the grand total sums the lines. Fix any formula Claude got wrong before moving on.
Create the tracker log sheet with one row per invoice and columns that match the invoice sheet. Ask Claude to link the two so a new invoice row copies into the log.
Add a status column with a dropdown for Paid, Outstanding and Overdue. Apply conditional formatting so each status shows a different colour.
Change a status on the invoice sheet and confirm the tracker log updates on its own. If it does not, check the sheet and cell references in the formula.
Build the dashboard sheet with SUMIFS formulas that total amounts by status. Point each formula at the status column and the amount column in the tracker log.
Test the full chain: add a new invoice, mark it Paid, and watch the tracker and dashboard totals change. Repeat with Outstanding and Overdue to confirm each total works.
Tips and common mistakes
Keep the input, log and summary sheets in that order so data only flows forward and you avoid circular references.
Save a copy of the workbook before you let Claude rewrite formulas, so you can roll back a bad change.
Use exact status text in your SUMIFS formulas, since a stray space in Paid or Overdue will break the total.
The Claude add-in needs a paid Claude plan, so check your subscription before you start.
Questions
Do I need a paid Claude plan for this?
Yes. The Claude add-in for Excel requires a paid Claude subscription. A free account will not connect the add-in.
Will the tracker update when I add a new invoice?
Yes, if the log sheet is linked to the invoice sheet with formulas or a table reference. Test it with one new row before relying on it.
Can I use this for other Excel systems?
Yes. The same three-layer pattern of input sheet, log sheet and summary dashboard works for expenses, inventory or project tracking.
