Pros and cons

Pros

  • Five distinct dialing modes including agent-assisted human dialing, which nothing else here offers
  • Managed caller ID reputation and a heat map for number health, which is the right answer to parallel dialing spam risk
  • Native Salesforce AppExchange package
  • 4.6 on G2 across roughly 396 reviews

Cons

  • The pricing table has numbers with no units, term or minimums attached, which is worse than not publishing at all
  • No minutes disclosure
  • No CRM, SMS or email
  • Reviewers report audio lag causing prospects to hang up

Contract and pricing details that change the bill

Where Koncert loses

Loses to Salesfinity for any buyer who needs a price in writing: Koncert's table attaches no unit, term or minimum to its figures, while Salesfinity publishes $299 month to month.

Every review on this site carries this section. The aggregate is on where DialSheet loses.

Full review

Koncert has the widest range of dialing modes of any vendor here and the least readable pricing page, and the second fact undermines the first.

The pricing page shows a table: Click Dialer $6, Flow Dialer $7, Agent-Assisted Dialer $29, AI Flow Dialer $79, AI Parallel Dialer $99. It attaches no unit to any of them. Not per user, not per month, not per seat, not per dial. There is no term, no minimum and no minutes disclosure, and the page directs buyers to contact sales. A number without a unit is worse than no number, because it invites the buyer to assume the flattering reading.

The product is better than the pricing page

Five distinct modes is unusual. Click dialing, single-line Flow, AI Flow, AI Parallel on one to five lines, and agent-assisted dialing where a human agent navigates the switchboard and hands the rep a live decision-maker.

That last mode is the interesting one. No software-only dialer reaches the connect rates a human navigator does against gatekept targets, and if your market is hard to reach by any automated means, agent-assisted dialing is a different product rather than a faster version of the same one.

Koncert's caller ID health monitoring and managed reputation are also better thought through than most. A heat map of number health, with managed rotation, is the correct answer to the spam-flag problem that parallel dialing creates, and most vendors in this category treat it as the customer's problem.

The native Salesforce AppExchange package is real and works properly.

The complaints

Reviewers report audio lag that causes prospects to hang up. That is the parallel dialer tax again, and Koncert's version is commented on often enough to take seriously. Test it on your own network during an evaluation.

There is no CRM, no SMS and no email. Like Orum and Salesfinity, this is a layer.

Who should evaluate it

Salesforce-native teams that want several dialing modes from one vendor and one contract. If some of your reps need click-to-call inside the record and others need parallel dialing against a cold list, buying both from Koncert is simpler than running two vendors.

Teams selling into hard-to-reach titles should look specifically at the agent-assisted product. It is the one thing on this list you cannot replicate with cheaper software.

Everyone else should make Koncert put its pricing in writing, with units, before spending time on a demo. A vendor that will not tell you the unit of its own price list is telling you something about the negotiation ahead.

Koncert FAQ

How much does Koncert cost?
Koncert's pricing page shows figures of $6, $7, $29, $79 and $99 for its five dialing modes but attaches no unit, term or seat minimum to them, and directs buyers to contact sales. As of September 2026 there is no way to know from the published page whether those numbers are per user per month or something else. Ask Koncert to state the unit in writing before evaluating.
What is Koncert's agent-assisted dialer?
Koncert's agent-assisted dialer uses a human agent to place calls and navigate switchboards and gatekeepers, handing the sales rep a live decision-maker once one is reached. It produces connect rates that software-only dialers cannot match against gatekept targets, and it is the one capability on Koncert's list that has no cheaper software substitute.
Does Koncert have a free plan?
No. Koncert has neither a free plan nor a publicly advertised free trial.
Can you bring your own Twilio account to Koncert?
No. Koncert provides the telephony itself, so minutes are billed inside the seat price rather than at wholesale. Sales dialers that do support bring-your-own-Twilio include DialSheet and Myphoner.
Who is Koncert best for?
Koncert is best for Salesforce-native teams that want several dialing modes from one vendor. It is a poor fit for buyers who need to know what something costs before a sales call.
