Timeliness Determines Credibility – Quantify It with Data.

In global sourcing and supply chain management, a supplier's punctuality is more than a courtesy—it's the bedrock of operational reliability. MuleBuy's On-Time Delivery (OTD) Rate Spreadsheet

The High Cost of Unreliability

Late deliveries cascade into production delays, missed sales opportunities, eroded customer trust, and increased safety stock costs. Without a clear measurement system, identifying chronically late suppliers or recognizing improving partners becomes impossible. MuleBuy's solution cuts through the ambiguity.

How the MuleBuy Spreadsheet Calculates Punctuality

Our structured spreadsheet template automates the tracking and calculation of each supplier's On-Time Delivery Percentage. Here’s the core methodology:

  • Data Inputs:Promised Delivery Date, and Actual Delivery Date.
  • Automatic Calculation:
  • Key Metric:Supplier-Specific On-Time Delivery Percentage(Number of On-Time Deliveries / Total Deliveries) * 100.
  • Dynamic Dashboard:

Transforming Data into Predictable Performance

Informed Supplier Selection

Compare historical OTD rates when awarding new contracts. Choose partners whose proven reliability aligns with your planning cycles.

Proactive Risk Management

Identify suppliers with declining punctuality scores early. This allows for proactive conversations, contingency planning, or phased diversification before a critical disruption occurs.

Strengthened Negotiations

Use concrete performance data in business reviews. Reward high-performing suppliers with more business and negotiate better terms or improvement plans with underperformers.

Accurate Lead Time Forecasting

Adjust your internal planning based on realistic delivery performance. If a supplier has a 90% OTD rate, your production schedule should account for the 10% risk variance.

Build a More Credible, Predictable Supply Chain

Stop relying on instinct and start managing by metrics. The MuleBuy On-Time Delivery Spreadsheet is your first step towards a transparent, accountable, and highly reliable supplier network.
