Same $29 entry price,
more on the entry plan.
DialZara is OnCallClerk's closest direct peer on pricing, with the same $29 starting point. The difference is what each product includes at that tier. On DialZara Business Lite, calendar booking, warm transfers and bilingual answering are gated behind the $99 plan. OnCallClerk includes calendar booking and transfers on entry, plus native HubSpot and Slack.
The $29 plan you actually want
DialZara Business Lite is $29/month with 60 included minutes. Here is what that gets you compared to OnCallClerk entry.

When DialZara is the right pick
DialZara is a credible product with a strong customer review base, particularly on Trustpilot, and noticeable strength in real estate. Their voice library is genuinely large at 50+ voices, and the Business Plus tier at $199/month with ongoing white-glove prompt engineering is unique: their team will iterate on your agent prompt as your business changes, which is valuable for operators who do not want to learn the prompt engineering side themselves.
Pick DialZara if you specifically want done-for-you prompt engineering as an ongoing service rather than a one-time setup. Pick DialZara if your call profile fits cleanly inside a 60, 220 or 500 minute bucket and the $0.48/min overage feels acceptable to you.
Pick OnCallClerk if you want calendar booking and warm transfers on the $29 plan, you live in HubSpot or Slack, you are a UK business or expect UK callers, or you want to resell the platform under your own brand.

How is OnCallClerk different from DialZara?
DialZara is the closest direct peer to OnCallClerk on price; both start at $29/month. The differences are in what is included on the entry plan and on the integration side. DialZara Business Lite at $29 has only blind transfers, no warm transfer, no bilingual support, no calendar sync, and no after-hours rules; those unlock at the $99 Business Pro plan. OnCallClerk includes calendar booking and call transfers on entry tiers. We also have native HubSpot and Slack integrations.
Is OnCallClerk cheaper than DialZara?
At the entry tier, the headline price is the same: $29/month. The real difference is what you can do with that $29. On DialZara Business Lite, calendar booking, bilingual answering, and warm transfers all require upgrading to $99/month. On OnCallClerk, calendar booking and warm transfers are included on entry plans. So the effective price for a feature-comparable setup is lower on OnCallClerk.
What about overage rates?
DialZara overage is $0.48 per minute on all plans. OnCallClerk overage is competitive and varies by plan tier; we publish current rates on the pricing page. Both products are clearly minute-priced (no credit pools, no per-customer math), which is the right approach for predictability.
Does OnCallClerk have native HubSpot and Slack like DialZara?
OnCallClerk has native HubSpot and Slack integrations. DialZara connects to third-party tools via Zapier and Make. Both approaches work, but native integrations are usually faster, more reliable, and require less setup. If your team lives in HubSpot or Slack, OnCallClerk is the more direct path.
Does OnCallClerk offer UK phone numbers like DialZara?
Yes. OnCallClerk operates a UK-registered legal entity and is rolling out UK phone numbers. DialZara provides UK numbers on request. The difference is that we are a UK business by registration, which matters for UK customers concerned about data residency, GDPR contracts, and which entity holds their data.
Does OnCallClerk have a white-label or reseller program?
Yes. OnCallClerk has a white-label program for agencies and resellers. You brand the platform as your own, set your pricing, and our infrastructure runs underneath. DialZara does not publicly list a white-label option but does offer a Business Plus tier with white-glove prompt engineering done by their team for you.
How fast can I get started?
About 10 minutes. You enter your business website and key information, the AI generates a starting prompt, you pick a voice, and you forward your number. DialZara advertises a similar 15-minute setup. Both products are easy to launch; the difference is in how much is configurable on the entry tier.
