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.

Its an all in one platform, from making work orders, sending SMS messages, to generating and sending invoices. Its very easy to use not only for the back office, but also for the customers that would prefer to submit work orders via an online portal.

support isnt 24/7 which means if theres issues during after hrs it most likely will not be handled until the next day.

It's disappointing because this could have been an opportunity for them to not only rectify a bad customer experience but potentially improve the product for others down the line.
