Checkout is the most expensive stretch of the site: every visitor who gets there has already cost media spend, content, and time. Yet most stores still lose between 60% and 80% of carts right there. This guide shows why that happens and how to reduce abandonment step by step.
Why people abandon their cart
| Reason | Signal in the store | Fix |
|---|---|---|
| Surprise shipping cost | Drop at the delivery step | Show shipping on the product page |
| Mandatory sign-up | Abandonment at login | Guest checkout |
| Too few payment methods | Exit at the payment step | Pix, card, and clear installments |
| Lack of trust | Return to the homepage | Badges, policy, and a contact channel |
| Long process | Progressive abandonment by step | Fewer fields and steps |
Five principles of a checkout that converts
- One thing at a time. No navigation, banner, or promotion competing with checkout.
- No surprises. Shipping, delivery time, fees, and installments visible before the last step.
- Fewer fields. Every field removed raises the completion rate. Fill in the address from the ZIP code.
- Errors handled clearly. A specific, inline message, without losing what was already typed.
- Visible trust. Social proof, exchange policy, and support one click away.
Checkout on mobile
- Numeric keyboard for ZIP code, tax ID, phone, and card.
- Autofill and autocomplete configured correctly.
- A fixed, always-visible primary button.
- Fields with a comfortable tap height and a persistent label.
Payment and recovery
A declined card is a silently lost conversion. Monitor the approval rate by card network and enable automatic retries. For people who left, build the recovery sequence:
- A message within one hour, with a direct link back to the checkout.
- A second contact at 24 hours, with social proof and delivery time.
- A third contact at 72 hours, with an incentive, only if margin allows it.
This sequence lives inside your marketing automation and gets stronger when combined with WhatsApp.
How to measure progress
Track completion by step, payment approval rate, average checkout time, and recovery by channel. Without that, changes become opinion, and the right move is to validate with A/B testing, feeding the store's conversion rate.
Optimized checkout checklist
- Guest checkout available.
- Shipping and delivery time shown before checkout.
- Address auto-filled from the ZIP code.
- Order summary visible at every step.
- Pix shown with a discount or clear advantage.
- Specific, inline error messages.
- Cart recovery active within one hour.
- Thank-you page with next step and tracking.
Conclusion
Optimizing checkout is the conversion work with the best return per hour invested: the traffic has already been paid for, the intent already exists, and every bit of friction removed turns straight into revenue.
Frequently asked questions about cart abandonment
What is the average cart abandonment rate?
The market average hovers around 70%, ranging between 60% and 80% depending on the segment and traffic quality. Stores with a lean checkout and transparent shipping sit at the lower end.
How do you reduce cart abandonment?
Show shipping and delivery time before checkout, allow guest checkout, reduce fields, offer clear installment and payment options, handle errors specifically, and enable recovery within one hour.
Single-page checkout or multi-step checkout?
A single page tends to convert better for simple purchases. Steps make sense for complex orders, as long as progress and order summary stay visible throughout.
Is it worth requiring account creation before purchase?
No. Mandatory sign-up is one of the biggest causes of abandonment. Offer guest checkout and invite account creation after the order is confirmed.
When should cart recovery messages go out?
The first contact should go out within one hour, the second within 24 hours with social proof, and the third within 72 hours with an incentive, only if margin allows it.
