The income statement of e-commerce and how to calculate it step by step.

The P&L of E-commerce step by step

We all should already know how an income statement, or P&L, works, and also how to set up a channel income statement for e-commerce. However, there are some details and precautions to consider if we want the income statement to correctly reflect reality.

Since how we calculate sales we can obtain useful information for the management of the e-commerce channel: for example we can calculate the average discount applied on the retail price.

Differences between company and company

It is important to underline that there is no single way to schematize (report) financial activities, even at the accounting level there are different standards that companies can use and, depending on the standard used, the formatting of the income statement of the e- commerce or other channel may be different.

The important is maintain consistency from one year to the next so you can view trends over time - trend - of the performance indicators - that they are consistent with each other. For example, if we calculate the cost of goods sold in one way in one year, we must calculate it in the same way the following year in order to be able to compare it.

E-commerce financial terminology

  • Top-line: revenues or sales
  • Bottom line: net profit or EBIT
  • COGS: Cost of Goods Sold or cost of goods sold
  • Standard cost: it is a way of calculating the cost of sales based on the cost of the components of the products: cost of the material used + cost of processing = cost of the product.
  • Gross sales: sales gross of returns and sometimes even gross of VAT (VAT)
  • Devaluation of products in stock: each product tends to lose value if it is not sold and remains in stock for a long time. For this reason, conventions and practices are defined for the devaluation of products in stock. These values are entered as costs in the income statement of the ecommerce channel.

E-commerce sales tracking: gross sales vs. net sales

Very often sales in e-commerce are called with the English term Sales or Revenue to which the prefixes Gross and Net are added.

Given that the use of English does not clarify or simplify the understanding of these terms, we explain clearly what these terms mean below.

Regardless of the accounting standard we adopt, the terms net and gross sales must be very clear within the company and must reflect the needs for tracking the results of the e-commerce channel with respect to targets.

Gross salesGross sales VAT included or receipt. It corresponds to the total amount paid by customers for the products purchased. Sometimes this concept is associated with the concept of "Demand" or the orders of end customers entered into the system before discounting any returns or delivery problems.
Gross sales before discountsIt refers to the theoretical price or list price that users would have paid if they had purchased without discounts. This metric is used to calculate the average discount applied by the e-commerce or retail channel compared to the list price and therefore also compare the performance between channels, for example which channel between e-commerce and retail offers more discounts?
Net Net SalesNet Net sales represent net sales returns and net VAT then Gross Sales - VAT - Returns = Net Net Sales
RevenueTurnover is an accounting data which means sales in VAT and Net Credi Notes issued + Any deferrals (estimate of credit notes not yet issued but pertaining to the reference period, for example year or quarter)

The calculation of e-commerce sales with the standard cost + mark-up method

If we calculate gross sales with the standard cost + mark up method, for example, we can accurately estimate sales gross of discounts. While if we calculate the sales on the basis of the collection we lose the information on the discount made.

The income statement of the e-commerce channel generally looks like this:

Sales gross = standard cost or industrial cost * mark-up
Industrial cost50
Mark up3
Selling price150
Total units sold in the period (e.g. one month)1.000
Gross turnover150.000
- Discounts 15.000
Gross sales net discount135.000
- Returns 35.000
= Net sales100.000

The reporting of returns in the income statement in ecommerce

Returns in e-commerce can be reported in two ways: through the date of receipt of the return in stock or through the date of issue of the invoice or sales receipt.

The first way does not require an estimate of the amount of returns that will be received in the period, as the returns are recorded in the accounting system after the physical receipt of the product. While with the second method it is necessary to estimate the returns that will be received after the expiry of each tax reporting period.

Let's take an example to explain this second method of calculating returns which, in my view, is the most correct: imagine you are managing an e-commerce of physical goods, let's say fashion products, you are on December 1st and you decide to extend the return period for all orders received from 1st to 31st December to the end of January of the following year. By doing so, you are effectively influencing the e-commerce operating result by artificially reducing the returns of the current period by moving them to the first quarter of the following year.

My operational recommendation is therefore to calculate the average return rate of the site and apply the average return rate in the calculation of returns at the time of closing the balance of the e-commerce channel.

The costs of e-commerce

The calculation of the COGS Cost of Sales in e-commerce

From an accounting point of view, the cost of sales is any cost directly related to the product sold or we are talking about a cost that occurs only if the product is sold.

For the correct calculation of the cost of goods sold we must take into account three factors:

  1. Buying e-commerce: therefore the fixed assets of products that we buy and allocate on the e-commerce warehouse with the aim of selling them over the course of one or more seasons and their degree of depreciation
  2. COGS are costs when we sell products and are revenues when we receive returns. This is a fact, you just have to remember to calculate them correctly.
  3. If the availability of salable goods on the e-commerce channel is not exclusively allocated to the e-commerce warehouse but is the sum of several warehouses, the cost of sales cannot be calculated on the value of the e-commerce buying or order.

What costs should be included in the cogs in the income statement?

One possible rule is to follow who they are costs directly related to the sale of the product, therefore the raw materials used and the cost of the labor used for the realization of the product. But what do we do with the fees paid to credit cards and sales commissions? These are also expenses that only occur if a product comes, but are generally reported lower in the e-commerce income statement.

The general practice is to carry the expenses related to sales commissions further down in the income statement, because if we included all the sales expenses in the cost of sales (COGS) we would obtain a lower gross margin. If you are a publicly traded company, having a significantly lower gross margin than the competition can create valuation problems.

What goes into the cost of sales of a company that produces software as a service?

In this case the software provided to the customer is the service we sell, so we will have to enter the cost of the servers and the people who maintain the servers in the cogs, if you pay royalties on the sales of the software these are also a cost of sales and if the company helps customers use the software, this could also be considered a cost of sales.

In conclusion, the best way to determine the components of the cost of sales is to look at what the leading companies in the sector do in the reference market and ask for indications from the auditors who will be able to give sufficiently clear indications and leaving you the choice of where to place some cost elements. Once this choice has been made, it is good to keep it for different accounting periods to have the possibility of making year-over-year comparisons and determining trends.

What we have not considered

  • Fixed costs and variable costs -> projection
  • KPI as the average discount rate
  • VAT and taxes
  • Indirect costs: business costs e.g. offices, accounting, general management

Capital investments in e-commerce

Capital investments are often seen as less important than operating costs, but that's not how it works in e-commerce.

Analysts often stop at the operating cost level to determine the sustainability of the income statement of the e-commerce channel. This means that investments in infrastructure, for example the creation of the e-commerce platform, are considered below EBITDA and therefore only fall within the calculation of EBIT otherwise known as profit before tax and interest on capital.

In e-commerce, unlike physical bricks and mortar channels, investments in infrastructure are continuous because technology is constantly evolving.
