Monthly eCommerce Performance Report Template: Our Structure

A monthly eCommerce performance report that supports real decisions starts in one place: store sales and orders in Shopify. Ad spend across every platform is then added to calculate MER and blended CPA, followed by the funnel and traffic sources, and finally a decisions section. This is the structure we use with every store E-SAFQA manages, explained section by section with a template you can copy into a spreadsheet.

Why the report starts from the store, not the platforms

The Meta dashboard says ROAS was 6x, the Google dashboard says 5x, and the merchant looks at the bank account and sees nothing that reflects either. The platforms are not lying; each one attributes the order to itself within its own attribution window, so orders are counted twice when added together, cancelled orders are included, and returning customers are credited to the last ad they saw.

So the first rule of our report: store sales are the truth, platform numbers are direction. The reasoning is covered in MER vs ROAS.

The monthly report structure we use

Section	Source	Question it answers
1. Executive summary	Everything below	Was the month profitable? What is the decision?
2. Store numbers	Shopify	Sales, orders, AOV, cancellations and returns
3. Spend by platform	Meta, Google, Snapchat, TikTok	How much we spent and where
4. Blended profitability	Store + spend	MER, blended CPA versus maximum CPA
5. Platform performance (directional)	Platform dashboards	Which campaigns improve or decline
6. Funnel and sources	GA4 + Shopify	Where customers leak and where they come from
7. Products and customers	Shopify	Best sellers, slow movers, returning share
8. Decisions and experiments	The team	What changes, why, and how it is measured

1. Executive summary

Five lines at the top: sales versus last month and the same month last year, MER, blended CPA versus target, the biggest win, and the main decision. A busy store owner reads only this section, and it must be enough.

2. Store numbers

From Shopify reports: gross sales, discounts, returns, net sales, order count, average order value and store conversion rate. Also record cancelled orders and the cash-on-delivery rejection rate where available, because in Gulf markets they quietly eat the order margin.

3. Spend by platform

A simple table: platform, spend, attributed purchases, attributed purchase value, platform ROAS. Write a permanent note above the table: these numbers are not to be added together.

4. Blended profitability

This is where the month is decided:

• MER = net store sales ÷ total ad spend across all platforms.
• Blended CPA = total spend ÷ number of store orders.
• Maximum CPA = contribution of one order after product cost, shipping, fees and average discount. The calculation is in eCommerce unit economics and contribution margin.

If blended CPA is below the maximum, the month was profitable regardless of what any ad dashboard says. If it exceeds the maximum, the month lost money even if platform ROAS looks excellent.

5. Platform performance: directional only

For each platform: the best three and worst three campaigns, the change versus last month, and notes on new creatives and ad fatigue. The aim is to know where to move budget inside the platform, not to compare platforms with each other. Cross-platform comparison happens in section 4 only, and it needs correct Google Ads conversion tracking and Meta tracking before it means anything.

6. Funnel and sources

From GA4: sessions by source, the progression from product page to cart to checkout to purchase, and device performance. A sudden drop in checkout-to-purchase points to a payment gateway or shipping problem, not to the ads. The correct setup is in our GA4 Shopify setup guide.

7. Products and customers

Best sellers and their margin, products viewed but not bought, returning-customer share, and the average time between first and second order. This section feeds next month’s promotions and inventory decisions.

8. Decisions and experiments

Every report ends with a table: decision, evidence from the report, expected impact, how it will be measured, and when it will be reviewed. Example: move part of the retargeting budget to the catalog campaign because its CPA has been lower for three consecutive months, review after 14 days. Decisions without written evidence do not enter the report.

The ready template

Copy these columns into a spreadsheet, one row per month:

Month	Net sales	Orders	AOV	Meta spend	Google spend	Other spend	Total spend	MER	Blended CPA	Max CPA	Conversion rate	Returning share

Add a second sheet for decisions with the same columns as section 8. After three months you will see trends that no ad dashboard shows.

Common mistakes in store reports

• Adding Meta and Google conversions into one number.
• Reading the report on the first day of the month before late conversions and cancellations settle.
• Comparing only with the previous month and ignoring seasonality (Ramadan, White Friday, back to school).
• Celebrating a rise in platform ROAS while blended CPA exceeds the maximum.
• A report with no decisions section, which turns it into an archive of numbers that changes nothing.

From our experience

With Brandat Jordan, a home appliance store, a monthly report in store and ad numbers together was a fixed part of management. That discipline is what allowed winning campaigns to be protected rather than restructured without evidence, and the store achieved a Meta ROAS between 7x and 20x for eight consecutive months from February to September 2026 with stable monthly sales. Details are in the Brandat case study. At Xmart, the electronics store, moving from platform ROAS to blended MER is what showed the account exceeding 10x in September 2026 from Meta and Google together.

E-SAFQA’s tracking and analytics service always ends with a unified monthly reporting dashboard that starts from store sales and is measured by MER.

Conclusion

A good monthly eCommerce performance report starts from Shopify, calculates MER and blended CPA against the order margin, shows platform numbers as direction, reads the funnel from GA4, and ends with written decisions backed by evidence. The structure is simple; the monthly discipline of applying it is what makes the difference.
