TABLE STRUCTURES & COLUMNS (INVOICES SHEET)

FIELDS FOR OFFICE MANAGEMENT INTEGRATION

This template is engineered for seamless integration into office management workflows:

• Auto-generated Invoice Numbers: Uses the formula =TEXT(TODAY(),"yyyymmdd")&"-"&TEXT(COUNTIF(Invoices!$A$2:$A$1000,"INV-"&TODAY()&"*")+1,"000").
• Client-Based Tax Rules: Tax rate is pulled dynamically using VLOOKUP from the 'Client Master List' based on client category (e.g., VAT-registered, charity).
• Due Date Logic: Formula: =IF(D2="","",D2+14).
• Total Calculations: Grand totals are computed using SUM functions across the 'Total (£)' column with a formula like: =SUM(E3:E100).

CONDITIONAL FORMATTING

To enhance visual clarity and team oversight, conditional formatting is applied:

• Overdue Invoices: If 'Due Date' is past today’s date AND 'Status' ≠ Paid → Highlight in red.
• Pending Payments: Invoices with no payment recorded → Yellow background.
• Status Indicators: Use icon sets (✅ for Paid, ⏳ for Pending, ❌ for Overdue) next to each invoice in the 'Status' column.
• High-Value Invoices: Invoices over £1,000 → Blue highlight with bold text.

INSTRUCTIONS FOR TEAM USE

1. Access Control: Use the 'Team Access & Permissions' sheet to assign roles. Only team leads should have edit rights.
2. Create New Invoices: Go to the 'Invoices' sheet and select a client from the drop-down in column C. Use item drop-downs for quick entry.
