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

  1. Week 1: Interviewed ops team, documented current pain points, mapped data flow.

  2. Week 2-3: Designed master file structure and migrated historical data.

  3. Week 4: Built billing schedule and dashboard views.

  4. Week 5-6: Trained team on data entry standards and month-end reconciliation process.

  5. Week 7-8: Parallel run, bug fixes, and handover.

Outcomes

AreaResult described in this case
Missed InvoicesReduced to near-zero (every service creates a billing expectation)
Renewal CaptureContracts expiring in 30 days now surfaced automatically
Admin TimeClient estimated approximately 25% reduction in contract management overhead
Leakage AvoidanceEstimated approximately 20 lakh per year through timely reminders
