Pricing model

Pricing changes often and each tool prices differently (per seat, per minute, per call, or usage based). Rather than freeze a number that goes stale, we link straight to each vendor’s own pricing page so you see the current model at the source.

What customers say

Verbatim public reviews, praise and complaints both, each linked to where it was posted. We do not edit or cherry-pick for tone.

Praise
Payzer can be used from inside the office as well as out in the field (service technicians). We have access to our records and can print and send receipts via e-mail with ease.

Complaint
Since it is so simple, it does not have the data that businesses need to make intelligent decisions. No worklow queues, no audit history, no paper trails, no accountability.
