Some back of the napkin math:
* $2.9+ billion in sales
* 25.5 million consumers
* Shopify Basic is 2.9% + 30¢ per transaction (ignoring $29 monthly cost.
* Shopify Plan is 2.6% + 30¢ per transaction (ignoring $79 monthly cost).
* Advanced Shopify is 2.4% + 30¢ per transaction (ignoring $299 monthly cost).
* Shopify Plus pricing starts at $2000 monthly.
If all merchants were on Shopify Basic:
* 2.9% of $2.9 billion = $84,100,000
If all merchants were on Shopify Plan:
2.6% of $2.9 billion = $75,400,000
If all merchants were on Shopify Advanced:
2.4% of $2.9 billion = $69,600,000
If 1 consumer ≅ 1 sale
$0.30 * 25.5 million = $7,650,000
So Shopify revenue for Black Friday weekend was between $77.25 million and $91.75 million
Obviously a lot of factors not taken into account there. But still. Nice work Shopify!
