Public prices checked on 20 October 2026 on flunter.com/pricing and sonik.ai/pricing, per user per month. At Flunter, one credit is one call placed, answered or not. Terms may change: check them with each vendor.

A few sessions a week and full days of prospecting are not the same need. Compare the entry price, but also the volume included.

The Flunter advantage: several entry levels. If your volume stays within the plan you pick, Starter or Hunter let you start at a lower listed price than Sonik. You can also pay monthly, with no annual commitment.

The point to acknowledge: for heavy use, the unlimited calling Sonik lists at €200 is worth a look. Flunter is not always the cheaper option.

Flunter prices shown do not include the quarterly or annual discounts. For Sonik, confirm which calls are covered and the price of Super Sonik, which is shown at two different amounts on its pricing page.

Make your dialer work with your organisation

If your teams already have their lists, the choice also comes down to the daily routine: importing a campaign, finding a contact's context and passing on the call outcome.

Flunter documents its connections to six CRMs: HubSpot, Salesforce, Pipedrive, Close, Boond Manager and Odoo. Call outcomes, AI summaries and recordings can be sent to the matching record. The full transcript stays available in Flunter.

Sonik names HubSpot and Salesforce, "most CRMs", LinkedIn, Gmail and Slack, and says calls, notes and outcomes are logged back automatically. To choose, check which actions are actually supported in your own setup.

The right test: launch a campaign from your CRM and check what your team finds after the call.

The conversation ends. The follow-up begins.

A prospect mentions a deadline, an objection or a next step. Those details need to stay at hand for the follow-up.

Flunter's AI summaries organise what was said in the conversation so the deal is easy to pick up again. The rep finds the key points, and a colleague understands the context without listening to the whole call again.

Check this on your own conversations: how accurate the summary is, whether it keeps the right points, and how useful it is for the next action.
