Customer reviews and service
Square provides free support on business days between 6am-6pm (PT) or 24/7 support on paid POS plans. Clover’s customer service is available 24/7 on all subscriptions.
Most payment companies get many negative reviews from their users, but those users are typically the victims of stringent security measures that block them out of their accounts. Since most Clover users get their own merchant account, payments are more stable and that’s why they get fewer complaints about that. Square, on the other hand, has received more complaints about frozen accounts and funds withheld, which is a typical mechanism to verify suspicious merchant activity.
On the other hand, customer support is some of the worst with Clover. Initially, you deal with the reseller who may provide great onboarding, but once you run into problems with the software, hardware or card payments, you have to deal with Fiserv.
It is rare to find positive reviews about Fiserv support, and many complain of hidden fees, faulty hardware and software glitches. Furthermore, each app from the Clover App Market has separate contact details for support, which can complicate matters.
Square also gets negative reviews about support, but at least they have the same contact information to handle all issues.
