These data indicate that offering a range of options and ensuring security are crucial to improving the user experience.

• E-commerce C: Offered interest-free installment payments, reducing cart abandonment by 20%.

These cases show that small changes can have a big impact on checkout completion rates.

Monthly report on sales and payment methods

Tracking monthly reports is essential to understanding how payment methods are performing. Here’s data from one of the e-commerce stores analyzed:

• Total sales: R$ 100.000
