Revenue vs profit in e-commerce: why selling more doesn't mean making more

What's the difference between revenue and profit in an e-commerce store?

Revenue (also called GMV or gross sales volume) is the total of what customers bought from you. If you sold $5,000,000 this month, that's your revenue. Sounds good. The problem is that out of that $5,000,000 you have to pay:

• The cost of goods sold (COGS): what you paid for the merchandise.
• Platform fees: Tiendanube, Shopify, Mercado Libre.
• Payment fees: Mercado Pago, Mobbex, Stripe — between 3% and 8% per transaction.
• Shipping and logistics costs.
• Advertising: Meta Ads, Google Ads, influencers.
• Fixed costs: employees, rent, tools, accountant.
• Taxes: VAT, gross receipts tax (IIBB), income tax.

What's left after all of that is your real profit. And for many Argentine e-commerce stores, that number is much smaller — or flat-out negative — than revenue suggests.

Why is it so easy to confuse revenue with profit in Argentina?

Because platforms put revenue front and center while costs are scattered across five different places. Tiendanube shows total sales on the main dashboard. Meta Ads shows conversion value. Mercado Pago shows what was credited to you. None of them show you the full picture of what you actually made.

On top of that, there are hidden costs many founders don't account for correctly:

• The cost of interest-free installments: if you sell in 12 interest-free installments with Mercado Pago, you absorb the financing cost — it can be between 12% and 20% of the sale value. Read more in the article on interest-free installments and your store's margin.
• Price changes without recalculating margin: when the dollar or supplier costs go up, many stores don't update selling prices in time — or they raise the price but don't cut ad spend on products that are no longer profitable.
• Returns and warranties: in some categories, 5-8% of sales get returned. That cost shows up fragmented and is never assigned to the product that caused it.
• The owner's time: if the founder works 60 hours a week in the business and it isn't counted as a cost, they're subsidizing the "profitability" with their own time.

Why isn't Excel enough to separate revenue from real profit?

The problem with Excel is the input data. To calculate real profit you need to cross:

• Sales by product (from Tiendanube or Shopify).
• The cost of each product (from the supplier, kept up to date).
• The exact fees for each payment method (which vary).
• Ad spend for each channel (Meta, Google).
• Shipping costs per order.
• The month's fixed costs.

In Excel, that's 6 different tables with data from 6 different sources, updated by hand, where one error in a VLOOKUP breaks the whole calculation. Most founders end up with a rough calculation that gives them an illusion of profit — not the real number.

The result: they think they have a 30% margin when it's 12%. Or they think they have 12% when they're losing 3%. You can read more about the hidden costs that destroy margin or learn how to calculate your real profit margin.

How does Escalafy show you real profit in real time?

Escalafy connects all your data sources in one place: Tiendanube or Shopify for sales, Meta Ads and Google Ads for advertising, Mercado Pago for processing costs, and the product costs you enter. With that, it calculates in real time:

• Net profit by day, week and month — not revenue, real profit.
• Real margin by product and by SKU — so you know which ones generate profitability and which destroy it.
• Profitability by sales channel (Tiendanube, Mercado Libre, Shopify).
• The real impact of advertising on profit — not the ROAS Meta reports, but real ROAS after all costs.
• Projected profit vs. actual profit — so you know whether you're on track for the end of the month.

You can see how this works in Escalafy's profitability by product section.

Frequently asked questions about revenue vs profit in e-commerce

What should the profit margin of an e-commerce store in Argentina be?

It depends on the category, but as a reference: a gross margin above 40-50% is healthy for most categories. A contribution margin above 15-20% lets you grow. A net margin above 8-12% is a good business. Below 5% net, any cost shock can push you negative. You can learn how to calculate it in the article on the break-even point in e-commerce.

Is GMV the same as revenue?

GMV (Gross Merchandise Value) is the total gross value of merchandise sold. It's equivalent to revenue before returns and discounts. It's the metric marketplaces use to show you how "big" you are — but it tells you nothing about your profitability. A business can have a huge GMV and negative margins.

How do I know if my e-commerce store is making or losing money without hiring an accountant?

The fastest way is to calculate contribution margin by product: selling price minus (product cost + payment fee + shipping cost + proportional share of advertising). If that number is positive for most of your products, you're contributing to covering fixed costs. If it's negative, every sale loses you money.

Which AFIP tax filings are mandatory for an e-commerce store in Argentina?

Depending on your revenue, you may be required to file monthly VAT, gross receipts tax (IIBB, per jurisdiction), annual income tax, and the information regime for sales made on digital platforms. Your accountant has to handle this — Escalafy doesn't replace your accountant, but it does give them the real sales and cost data so your tax filings are correct.

When does it make sense to hire more staff or invest more in advertising?

Only when you know your real margin can take it. If your contribution margin is 12% and you want to invest $500,000 more in advertising next month, you need to generate at least $4,200,000 in additional sales for the cost to break even. Without that clarity, you're hiring and spending based on feelings — not data.
