Does the job

Pretty happy overall. The integrations just works and it saves real time. The mobile experience lags can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the automation — handled better than most — and the value for money is strong. Worth the time if this is your use case.

Solid for our team

We rolled this out across the team last quarter and it saves real time. The core workflow fits neatly into how we already work, and the dashboard removed a step we used to do by hand. Pricing gets steep at scale, which is the main caveat, but it has held up under daily use.

Use it every day

Honestly didn't expect to like it this much. The integrations is exactly what I needed, and support is responsive. I do wish pricing gets steep at scale, but I reach for it almost every day now and it just clicks.
