Frequently asked questions

What are the best online payment processing companies for a small store?
It depends on volume and platform, but flat-rate providers with no monthly fee are usually the easiest starting point for a new online store.
How do online payment processing companies charge fees?
Most charge a percentage plus a fixed amount per transaction, and some add a monthly fee, gateway fee, or minimum processing volume.
Can I switch payment processing companies without downtime?
In most cases yes, especially with hosted checkout or API-based integrations, though you'll want to run both in parallel briefly before fully switching.
