5 Signs You Need This Template Right Now
1Messy Interim Certificates: You manually calculate gross, previous, and current amounts every billing cycle — and errors slip through unnoticed.
2Retention Tracking Headaches: Deduction percentages, release milestones, and cumulative balances live in different files with no single source of truth.
3Variation Orders Out of Control: Approved changes get lost between emails and meeting notes, making it impossible to reconcile the final account.
4Slow Payment Reporting: Preparing a financial summary for management takes hours of copy-pasting across multiple tabs.
5No Clear Financial Picture: You cannot answer a simple question — how much has been billed vs. paid vs. retained — without digging through folders.
