TABLE STRUCTURES AND COLUMN DEFINITIONS

Each sheet employs a relational structure with clearly defined tables that ensure consistency and reduce data duplication.

• Unit Price: Currency format with automatic validation for positive values.
• Total Line Item: Calculated using formula =Quantity * Unit Price.
• Tax Rate (%): Percentage input (e.g., 8.5%) – validated as numeric between 0 and 100.

• Status: Dropdown with options: “Draft”, “Sent”, “Paid”, “Overdue”.

4. Dashboard Summary Sheet

• Productivity Score: A composite metric based on invoice processing time and payment velocity.

FORMULAS REQUIRED

The following key formulas are embedded throughout the template:

• =CONCATENATE("INV-",YEAR(TODAY()), "-", TEXT(ROW(A1), "000"))) – Generates invoice IDs.
• =B3*C3 – Calculates line item total.
• =SUM(D2:D10) – Total of all line items.
• =D11*(E11/100) – Tax amount calculation.
• =SUM(E2:E4) + F2 – Final invoice total (before tax).
• =TODAY()-C3 – Days overdue (if due date passed).
• =IF(B2="Paid", "Completed", IF(B2="Sent", "In Transit", "Pending")) – Auto-status update.
• =COUNTIFS(Dashboard!F:F, ">0") – Count of overdue invoices.
• =AVERAGEIFS(G:G, G:G, ">0") – Average collection time.

CONDITIONAL FORMATTING RULES

To enhance visibility and productivity:

• Overdue Invoices: Cells in the "Days Overdue" column highlight red if > 15 days.
• Payment Status: "Paid" rows turn green; "Sent" rows show blue; all others remain gray.
• Tax Rate Field: Yellow warning if value exceeds 20%.
