Identify the key performance metrics

To select supplement suppliers, start by analyzing metrics such as:

• Total sales: how many units were sold in the last quarter?

• Profit margin: what’s the average margin per product?

• Return rate: what percentage of products are returned?

• Customer satisfaction: what’s the average rating and what are customers saying?

These metrics help you understand each supplier’s performance and whether a partnership makes sense.

Use bi tools to visualize sales data

Use Business Intelligence (BI) tools to compile and visualize data. With platforms like Google Data Studio or Power BI, you can:

• Create sales charts by period, product, and supplier.

• Identify performance trends and seasonality.

• Compare different suppliers’ performance in real time.

These visualizations make it easier to spot patterns and make decisions.

Compare suppliers based on track record and feedback

Evaluate suppliers based on their delivery track record and customer feedback:

• Research e-commerce platforms and social media to understand their reputation.

• Analyze delivery consistency and product quality over the last six months.

• Consider the number of complaints compared to sales volume.

A supplier with a solid track record and positive feedback tends to be more reliable.

Plan sample tests using performance data

Before signing a contract, test samples:

• Select products from different suppliers and analyze sales performance during a test period (e.g., 30 days).

• Track performance metrics during the test, such as conversion rate and return on investment (ROI).

• Use this data to refine your supplier selection.

Analyzing performance over time is crucial for making informed decisions.

CREATE A DASHBOARD TO MONITOR RESULTS AND MAKE ONGOING ADJUSTMENTS

Build a dashboard that brings all the relevant information together:

• Include sales metrics, customer satisfaction, and feedback in one place.

• Update the data weekly to monitor performance changes.

• Use tools like FreeSpy to analyze the competition and adjust your strategy as needed.

An effective dashboard allows for ongoing adjustments and improves overall performance.
