What costs are included in the MerchantSpring P&L report?

MerchantSpring’s Profit & Loss (P&L) reports combine Amazon financial event data with optional cost inputs to calculate overall profitability.

The P&L report is designed to show the complete financial picture of marketplace performance, including revenue, fees, refunds, and operational costs.

Core Cost Categories Included in P&L

Amazon Referral Fees

Amazon charges a referral fee on most sales, typically calculated as a percentage of the product price.

These fees are automatically retrieved through Amazon’s financial APIs.

Fulfilment Fees

If products are fulfilled through Amazon FBA, fulfilment fees are applied based on factors such as:

• product size

• shipping weight

• packaging requirements

These fees appear as financial events within Amazon’s accounting data.

Storage Fees

Amazon charges storage fees for inventory stored within FBA warehouses.

These fees may include:

• monthly storage fees

• long-term storage fees

These events are included in financial reporting.

Refund Costs

Refunds reduce total revenue and may include additional processing fees.

These events appear in the P&L using Amazon’s posted financial event date.

Promotional Discounts

Coupons, promotional rebates, and discounts reduce the net revenue generated by a sale.

These adjustments are reflected through Amazon’s financial data.

Cost of Goods Sold (Optional)

Users may upload Cost of Goods Sold values for products.

When available, these costs are included in the P&L calculation to determine product-level margin.

Advertising Spend (Optional)

If Amazon Advertising integrations are enabled, campaign spend may be included in profitability calculations.

This allows businesses to measure the impact of advertising on profit.

Notes: 

• Some costs depend on optional data inputs such as COGS or advertising integration.
• Financial events may appear later as Amazon posts adjustments.
• Reviewing reports over longer periods helps ensure all costs are included.
