Why people leave with a full cart.
THE MAIN CAUSES
Unexpected costs appearing at the end Forced account registration A long or confusing form Payment methods they do not have Not trusting the site Slowness
SHOW COSTS EARLY
Delivery cost stated before checkout, not revealed at the final step.
That is the single largest cause of abandonment.
ALLOW GUEST CHECKOUT
Forcing registration loses sales.
Offer account creation after purchase instead.
SHORTEN THE FORM
Ask only for what you need to fulfil the order.
Every optional field costs conversions.
OFFER THE RIGHT PAYMENT METHODS
For Nigerian customers, card and transfer at minimum.
SHOW TRUST SIGNALS
Real contact details, a real address, clear policies, HTTPS.
MAKE IT WORK ON A PHONE
Test it there. Fields that are hard to tap lose sales.
WHAT TO MEASURE
How many reach checkout against how many complete.
