Sheet Names

The template includes a single primary sheet named:

• Invoice Master: The main workspace where all invoice data is captured and managed.
• Invoice Summary (Hidden): A dynamic summary sheet used internally to auto-calculate totals, due dates, and status updates. This sheet remains hidden by default for user simplicity but can be accessed via a button or tab in the interface.

Table Structures & Data Layout

The central data table in the Invoice Master sheet is structured as a clean, relational table with clearly defined sections:

• Header Section: Contains business name, address, contact details, invoice number (auto-generated), date issued, and due date.
• Itemized Services/Products Section: Lists each line item with quantity, description, unit price (with currency), and extended amount (calculated).
• Footer Summary: Automatically computes subtotals, taxes (e.g., VAT or GST), and grand total.
• Status Tracker: A single column for tracking invoice status: "Draft", "Sent", "Paid", or "Overdue".
• Payment Details: Captures payment date, method (e.g., Bank Transfer, PayPal), and reference number.
• Client Information: Includes client name, address, email, phone number—critical for business operations visibility.

The table includes the following columns with defined data types:

• Invoice Number: Text (auto-numbered via formula using today's date and sequential counter).
