Tips for choosing the right payment gateway for your business
When it comes to payment gateways, there’s a lot to consider and it can be hard to streamline your approach. To help with this, we’ve created a handy list of what to look out for when it comes to choosing the perfect payment gateway for your startup.
This is important for both you and your customers. Keep your eye out for PCI-compliance (crucial for accepting credit card payments)
- Data portability
Who owns your customer’s data if you choose to leave your gateway?Make sure you know how to download and move the data you need to sustain your merchant services without breaking GDPR
- Hosted/integrated gateways – what’s the difference?
– A hosted gateway will redirect your customers to the payment processor’s platform (they’re easy to set up and ideal for new businesses)
– An integrated gateway connects to your eCommerce website via the gateway’s provided API (meaning that your customers will never leave your site to input payment information)
- The customer journey
Customers will be looking for convenience, clarity and security – things to avoid include too many steps and too many details required from the customer, as this will take too much time and increase the chances of the customer abandoning the purchase
- Cards accepted
It’s standard for payment gateways to accept all major credit and debit cards, but double check (and if the gateway accepts American Express, that’s a bonus – be sure to check the processing fees though!)
- Mobile optimisation
Phones are the future of e-commerce, and if your payment gateway isn’t geared up for smartphones, then you’re probably missing out on some serious sales opportunities
Each payment gateway charges a different amount for credit, debit and overseas transactions – so be sure to swat up on what the charges are and make sure you’re not going over budget
- Customer support
If your gateway goes down, you won’t be able to accept payment for your products (which is bad news for business) so it’s important that your payment gateway provider has an efficient customer support network that can help out with any problems, any time
