Zendo alternative
Zendo vs ClientOS: rent a portal, or own one.
Zendo is a hosted platform for selling and delivering productized and subscription services, with a storefront, requests, quotes and invoices. ClientOS does the same on your own server, paid for once.
The short answer
Zendo is close to ClientOS in spirit, with a storefront, subscriptions and no transaction fees, but it prices every user and keeps branding removal for its top plan. ClientOS has no seat fees, is fully white-label and runs on your server.

A fair reading
Where Zendo is strong, and where it pinches.
Zendo is a good product, and for some agencies the right one. Here is what it does well, and why agencies on it look at ClientOS.
What Zendo does well
A generous free tier
A free plan to start, and a 14-day trial of Pro without a card.
Strong subscription selling
Trials, pauses, add-ons and a multi-step checkout, with no transaction fees.
Many languages

Why agencies move to ClientOS
Seat fees on every plan
Each plan includes one user, then $8 to $17 a month each. ClientOS has no limit.
White-label without the top plan
Removing “Powered by Zendo” needs Agency. ClientOS never shows its name to your clients.

Zendo lists Stripe and bank transfer. ClientOS adds PayPal and three crypto gateways.
