Table Structures and Columns (Monthly Forecast & Billing Tracker)

Formulas Required for Automation and Intelligence

• E5 (Forecast Accuracy %): =IF(B5=0, 0, C5/B5) — Prevents division by zero; returns percentage accuracy.
• H5 (Status Indicator): =IF(E5>=1, "Over Achieved", IF(E5>=0.9, "On Track", "Below Forecast")) — Visualizes performance relative to goals.
• F5 (Outstanding Invoices): =SUMIFS(‘Historical Data’!C:C, ‘Historical Data’!A:A, ">="&DATE(YEAR(TODAY()), MONTH(TODAY())-1, 1), ‘Historical Data’!A:A, "<"&DATE(YEAR(TODAY()), MONTH(TODAY()), 1), ‘Historical Data’!D:D, "<>Paid") — Pulls unpaid invoices from past data.
• G5 (Days in Collection): =IF(D5=0, 0, SUMPRODUCT((‘Historical Data’!B:B=MONTH(TODAY()))*(‘Historical Data’!C:C))/D5) — Average collection time using weighted data.

Conditional Formatting Rules

To enhance visual clarity and enable quick decision-making, the template applies intelligent formatting:

• Status Column (H): Color-coded cells: Green for "Over Achieved", Yellow for "On Track", Red for "Below Forecast".
• Forecast Accuracy (E): Green if ≥ 100%, Orange if 90–99.9%, Red if below 90%.
• Outstanding Invoices (F): If > $5,000, highlights in red to flag potential cash flow risks.
• Forecast vs Actual Comparison: Uses data bars in B and C columns to show relative magnitude at a glance.
