Salesforce does not dial
Salesforce Sales Engagement, formerly High Velocity Sales, adds cadences and a click-to-call experience. It is not a power dialer: there is no auto-advance session, no answering-machine detection and no parallel dialing. Every serious Salesforce dialing setup is a third-party tool.
That leaves three architectures, and picking the right one matters more than picking the vendor.
The three architectures
Native AppExchange package. The dialer installs into Salesforce and dialing happens inside the platform, with activities written natively. Koncert is the strongest example. Best for organisations where Salesforce is the system of record and admins control the interface.
External tool with a sync. The rep dials in the vendor's own interface and calls sync back to Salesforce. Orum, Salesfinity and Kixie work this way. Best when dialing throughput is the priority and Salesforce is the reporting layer.
Browser layer. A Chrome extension that adds dialing on top of the Salesforce UI without moving data. Trellus is the only real option here. Best when RevOps will not approve a new system and reps already work in Salesforce all day.
The architecture usually gets chosen by the organisation rather than by the sales team. Ask your Salesforce admin which of the three is acceptable before you shortlist anything.
Where the money goes on a Salesforce stack
An SDR seat on Salesforce with a parallel dialer is one of the most expensive seats in software.
| Layer | Typical monthly |
|---|
| Salesforce Sales Cloud | $100 to $165 |
| Sales Engagement / cadences | $75+ |
| Contact data | $50 to $100 |
| Parallel dialer | $250 to $420 |
| Per SDR | $475 to $760 |
Against a fully loaded SDR cost of roughly $7,000 a month, that is 7 to 11 percent of the seat, which is defensible for a funded team and painful for anyone else.
The cheaper architecture nobody proposes
If your reps dial from a list rather than from a Salesforce view, the Salesforce integration is doing very little work. The list gets built somewhere else, the rep calls down it, and the outcome needs to land in Salesforce.
That is an API or CSV problem, not an integration problem, and it costs $29 a month for three seats rather than $250 a seat. The tradeoff is real: activities sync on a schedule rather than instantly, and there is no dial-from-the-record experience.
Whether that tradeoff is acceptable depends on one question: does anyone actually look at call activity inside Salesforce in real time? In most organisations the answer is no, and the reporting is weekly.
The question to ask your Salesforce admin first
Will you approve an AppExchange package, a browser extension, or neither?
That answer eliminates most of this list before you look at a feature. Teams that shortlist first and ask second lose weeks.
