If you experience any delays in the payment process, have a professional developer investigate the issue. You can hire experienced freelance developers for around $40 an hour or less , which will coo email list substantially less expensive than going through a company or agency.
Make sure your customers know your security measures
As mentioned above, all payment options on your website should be PCI-DSS certified without exception. Make sure customers know this by placing a small but legible print stating that your payment options come with PCI certification. This action alone will go a long way to reassuring customers who may be a little worried about the security of their payment information.
Inform clients of all costs in advance
The checkout page shouldn't be the first time customers see taxes, shipping, or additional fees that come with a product or service. Provide this information earlier in the process, before the customer checks out.
Too many customers add items to shopping carts and then go to checkout pages only to abandon the process there when they suddenly see it. Customers who know this information beforehand and still go to the checkout page will be more serious about purchasing the items in their cart. So this action may reduce the number of customers who go to the checkout page in the first place, but it should increase the number of customers who complete the checkout process and order the product once they are there.
Allow customers to save their shopping carts
Another common scenario is how customers load up their shopping carts, go to the checkout page, and then abandon the process because they think better of it and suddenly decide they don't want to proceed with the order. However, many of these customers may have "third thoughts" and decide to purchase the items after all, only to be put off by the fact that they have to search your store again.
That's why you should always allow customers to save their shopping carts so they can come back to them later if they change their mind. It will make things much easier for customers who change their mind.
