• Service/Product Description (Text): Free text field for detailing services rendered or goods supplied.
• Quantity (Number): Numeric input representing units or hours provided.
• Unit Price (Currency): Price per unit; pulls default from the Product/Service Catalog.
• Tax Rate (%) (Percentage): Auto-filled based on client’s tax category; defaults to 0% for non-taxable clients.
• Subtotal (Currency, Formula-Driven): =Quantity * Unit Price
• Tax Amount (Currency, Formula-Driven): =Subtotal * Tax Rate

• Status (Text with Dropdown): Options: Draft, Sent, Paid, Overdue. Used for tracking payment lifecycle.
• Notes (Text): Optional field for internal comments or special instructions.

Required Formulas

To ensure dynamic and accurate data collection, the following formulas are implemented:

• =IF(AND(C2<>"", D2=""), C2 + E1, ""): Automatically calculates due date based on issue date and payment terms (E1 contains days in terms).
• =VLOOKUP(Client Name, ClientMasterList!$A:$D, 4, FALSE): Pulls tax rate based on client.
• =SUMIFS(InvoicesData!$K:$K, InvoicesData!$J:$J, "Paid"): Used in the dashboard to calculate total collected revenue.
• =IF(Today() > DueDate, "Overdue", IF(Status="Paid", "Paid", "Pending")): Auto-updates status based on current date and manual input.
• =SUMIFS(InvoicesData!$K:$K, InvoicesData!$J:$J, "<>Paid"): Calculates total amount still outstanding.

Conditional Formatting Rules

To enhance data visualization and user awareness:

• Overdue Invoices: If Status ≠ Paid AND Due Date < Today(), the entire row turns red.
• Pending Payments: Rows with Status = "Pending" are highlighted in yellow.
• High Value Invoices: Invoices over $5,000 are formatted with a green border and bold text.
• Auto-Update Indicator: Cells containing formulas display a subtle blue background to distinguish them from user input fields.
