Product cost helps you measure business profit. In Bitrix24, product cost data is included in the gross profit report. Use this report to see how much your company earns and decide if you need to adjust prices.

Choose a costing method

A costing method (also called a write-off method) defines how Bitrix24 calculates product cost. Your choice depends on your business model, product type, and accounting policy.

Bitrix24 supports two methods:

• First in, first out (FIFO)
• Average cost

To select a method:

1. Go to Inventory management.
2. Open Settings.
3. Select Common parameters.

FIFO

FIFO assumes you sell the oldest inventory first.

This method reflects real stock movement and reduces the impact of inflation on costs.
Calculate product cost by FIFO method

Average cost

Average cost calculates a single cost for all items in stock. It does not consider purchase date or price differences.

This method keeps costs stable and predictable. It works well for businesses with steady pricing, such as construction materials or long-shelf-life goods.
Calculate product cost by average cost method

View the gross profit report

After you select a costing method, you can track gross profit.

To open the report:

1. Go to Inventory management.
2. Select Analytics.
3. Open Gross profit.

The gross profit report shows the difference between sales revenue and the cost of goods sold. Higher gross profit means better business performance.

Profitability shows gross profit as a percentage of total revenue. A higher percentage means you control costs well and generate strong profit. Use this metric to decide if you should adjust prices or switch suppliers.

How canceled inventory documents affect the report

Employees manage inventory and may make mistakes. For example, they might move items to the wrong warehouse or add extra stock. When you correct these errors in Bitrix24, the report data does not change.

Example:

1. An employee adds 20 extra monitors by mistake.
2. Stock increases to 100 units.
3. After you cancel the stock receipt, stock returns to 80 units.
4. Previous documents stay the same. Only the current balance updates.

If you cancel a document after goods are received, make sure enough items remain in stock. Otherwise, you cannot cancel the document.
