Table Structures and Columns (Bill Tracker Monthly Sheet)

The primary data table on the 'Bill Tracker (Monthly)' sheet follows a normalized relational structure optimized for both manual input and automated validation. The table is named "tblBills" for consistent referencing in formulas.

Formulas Required

• BILL-YYYYMM-NNN ID Generator: Uses =TEXT(TODAY(),"YYYYMM")&"-"&TEXT(ROWS(tblBills)+1,"000") in a helper cell with an INDEX/MATCH to auto-generate IDs.
• Overdue Status Check: =IF(AND(Due Date"Paid"), "OVERDUE", IF(Status="Paid", "PAID ON TIME", "ON SCHEDULE"))
• Total Amount Paid: =Bill Amount + Tax Amount (Currency formatted).
• Days Until Due: =Due Date - TODAY()
• Monthly Total by Category: Use SUMIFS with dynamic date range based on month/year from the header.

Conditional Formatting

To enhance visibility and audit readiness, the template employs strategic conditional formatting:

• Overdue Bills: Red background with white text for bills with Due Date before TODAY() and Status not "Paid".
• Pending Approvals: Yellow highlight for any bill where Status is "Submitted for Approval" or "Approved" but no payment date.
• High-Value Bills: Orange background for bills exceeding $10,000 in Total Amount Paid.
• Aging Analysis: Color scale (Green → Yellow → Red) based on Days Until Due to visualize payment risk.
