What is COGP (Cost of Goods Purchased) and how is it calculated?

Understanding Your Store’s COGP

Reading this will take just a few minutes and will help you better understand how to control costs and improve your store’s profitability.

COGP (Cost of Goods Purchased) shows, in a simple and accurate way, how much your store spends on inputs in relation to its revenue.

With Visio’s COGS Report, you can track this indicator in an automated, visual, and practical way—making it easier to control costs and increase profitability.

What is COGP and Why Does It Matter?

COGP is an indicator that represents the percentage of input purchase costs relative to your revenue. It clearly shows how much of what you sell is being consumed by ingredient purchases.

Formula:

COGP (%) = Total Purchase Value / Revenue × 100

This number is essential to:

• Monitor and reduce waste
• Evaluate the real profitability of the operation
• Adjust purchasing and pricing strategies
• Plan promotions based on concrete data

How Does Visio Calculate COGP?

To generate the COGS Report accurately, Visio needs access to the XML files of your purchase invoices.

These documents are essential to identify:

• What was purchased
• When the purchase occurred
• Which suppliers were involved
• The cost of each purchase

This ensures a reliable analysis of your operational expenses.

The safest and most efficient way to do this is through your Digital Certificate.

Submit Your Digital Certificate Securely

If you already use an A1 Digital Certificate (installed on your computer, without a token or card), it can be used by Visio to automatically access your purchase invoices directly from SEFAZ.

You do not need to purchase a new certificate. If you already use an A1 certificate in your accounting, it will work perfectly.

How to submit:

Fill out our form and attach the certificate file along with its password.

What Will You Find in the COGP Report?

Weeks Filter (Time Period)

The report data follows the operational week defined by your network (for example, from Wednesday to Tuesday).

When you select a date range, the report considers all operational weeks that started within that range.

This is important because purchases in your business are made for the entire week, not for isolated days.

To accurately compare revenue and purchases, the full operational week must be analyzed.

Example:

If your operational week runs from Wednesday to Tuesday and you select the period from July 1st to July 31st, the report will display the weeks that started within that range (07/02 to 08/05) — including days in August, since they belong to the last operational week of the selected period.

This method ensures a more accurate view of your operation’s profitability.

General Indicators Dashboard

At the top of the report, you’ll find the main financial indicators of your operation—already considering factors that directly impact store profitability:

• Net COGP (%)
• Net revenue
• Total purchase value
• Net profit margin

All data is based on net revenue, which represents the actual amount entering your store’s cash flow after deducting delivery platform fees (such as iFood).

Example:

If your store had R$5,000 in iFood orders and the commission rate is 22%, the report considers R$3,900 as net revenue.

This adjustment provides a more accurate understanding of profitability, enabling better strategic decisions based on real data.

COGP Variation Charts (Monthly and Weekly)

Visualize how COGP evolves over time.

This analysis helps you:

• Detect cost spikes or efficiency improvements
• Evaluate the impact of promotions, menu changes, or inventory adjustments
• Make decisions based on historical data and real patterns

💡 Tip:

Decreases in COGP indicate better efficiency.

Increases in COGP may signal waste, price increases, or lack of purchase control.

Purchases by Supplier Table

See who you spend the most with and in what proportion:

• Number of purchases
• Percentage share by supplier
• Total amount spent

Use this view to verify purchases made by each supplier within the selected report period.

COGP and Margin Comparison Across Stores

Ideal for multi-store franchisees, this chart compares:

• Revenue
• Delivery share
• Net margin
• COGP for each unit

With this view, you can:

• Identify which stores are more efficient
• Replicate best practices
• Correct localized inefficiencies
• Foster a culture of continuous improvement and healthy competition

Cost Variation Analysis by Item

Analyze how costs have changed for each ingredient over recent months—both in absolute value and percentage.

This allows you to:

• Identify unnoticed cost increases
• Find products that became cheaper and created margin opportunities
• Adjust pricing, inventory, or supplier negotiations based on real and updated data

Real example:

Reductions in the cost of lettuce, tomato, and onion can generate over R$2,500 in additional profit in a single month.

Excluding Items from the Calculation

🔎 Found an item that should not impact your operational costs?

Use the “Items to exclude” filter to remove it from the COGP calculation.

This ensures your analysis only considers inputs that are truly part of the operation, making your cost evaluation more accurate and strategic.

Purchase Invoice Report

This section centralizes all your operation’s purchase invoices with:

• Dates
• Values
• Suppliers
• Invoice numbers

Use it for accounting checks, audits, and to ensure everything is aligned with your financial planning.

It also helps identify patterns and seasonality in purchasing.

How to Interpret Charts and Indicators

Keep these points in mind when analyzing your data:

• Ideal COGP: varies by operation type, but generally the lower, the better
• A sudden increase may indicate operational issues
• Monitor inputs with the greatest impact on revenue
• Compare similar stores to identify inefficiencies
• Combine COGP with Visio Pista data to understand waste and rejected products
