The business context
A field-service company managing annual maintenance contracts across 200+ client sites had grown organically. Everything lived in one evolving spreadsheet. Over time, columns were added for quarterly service logs, payment tracking, and rate revisions. The sheet had become unmaintainable, and the business was leaking revenue.
The challenge
Fragmented Records
Contract start dates, end dates, and rates were being overwritten when terms changed. Historical data was lost.
Missed Invoices
Service visits were completed but billing was delayed or missed because there was no trigger connecting service to invoice.
Renewal Leakage
Contracts expiring in the next 30 days were not flagged. Renewals happened reactively, often after the contract had lapsed.
What we found
What we changed
Separated Masters
Created three linked sheets: Client Master (company-level info), Site Master (location details), and Contract Master (one row per contract, no overwrites).
Data Validation Rules
Implemented dropdown validations so contracts could only reference existing clients and sites. Prevented typos and duplicates.
Auto Billing Schedule
Formula-driven sheet that generates expected billing dates based on contract terms. Service completion triggers billing expectation.
Dashboard Views
Summary views showing: overdue payments, contracts expiring in 30/60/90 days, sites with missed services, and revenue by client.
Implementation
Week 1: Interviewed ops team, documented current pain points, mapped data flow.
Week 2-3: Designed master file structure and migrated historical data.
Week 4: Built billing schedule and dashboard views.
Week 5-6: Trained team on data entry standards and month-end reconciliation process.
Week 7-8: Parallel run, bug fixes, and handover.
Outcomes
| Area | Result described in this case |
|---|---|
| Missed Invoices | Reduced to near-zero (every service creates a billing expectation) |
| Renewal Capture | Contracts expiring in 30 days now surfaced automatically |
| Admin Time | Client estimated approximately 25% reduction in contract management overhead |
| Leakage Avoidance | Estimated approximately 20 lakh per year through timely reminders |
