A website and an IDX with a CRM attached, priced by the site
6Degrees vs Sierra Interactive
Sierra sells a website, an IDX search that converts, and a CRM to work what the website catches. Read its pricing page and the shape is obvious: the price is per site, not per seat. If you have no website problem, you are buying a website.
The short answer
Pick Sierra if you need a website that ranks and converts, and the CRM is a bonus. Pick 6Degrees if your site is fine and your problem is a referral fee you cannot evidence. These two barely overlap, and plenty of agents should run both.
Eight points, side by side
Checked 13 August 2026 against sierrainteractive.com/pricing. These are the eight things 6Degrees is built to win, which is the honest way to read any vendor’s table: it is our axis, and you are allowed to decide it is the wrong one.
| What it does | 6Degrees | Sierra Interactive |
|---|---|---|
| Whose ledger it is | YesYours. It spans every agent and brokerage you refer to. | YesYours, for as long as you pay for the site. |
| Timestamped lead registration | YesYes. The server sets the date. The client cannot. | NoLead source and date are captured. There is no claim object on top of them. |
| Claim validity window | YesYes, where you want one. A booked showing extends it 30 days. | NoNo claim window is published. |
| Published tie-break rule | YesYes. First verified tag, and the buyer’s own confirmation outranks it. | NoRound-robin routing, which decides who works a lead, not who earned it. |
| One ledger across every brokerage you work with | YesYes. Every referral you have sent or received, in one ledger. | NoNothing models an outside agent or a referral fee. |
| Server-dated interaction trail | YesYes. Create-only. Nobody can backdate or delete a call. | PartlyActivity logging, editable after the fact. |
| Evidence pack you can put in front of a broker | YesYes. One dated pack: terms, timestamp, confirmation, site visit, timeline. | NoNo. Reports export, but nothing assembles a dated file about one referral. |
| Self-serve export and cancel | YesYes. CSV and JSON, any day, no ticket. | PartlyPublished price, but $0 setup only on annual. Monthly costs $500 to start. |
What Sierra Interactive does better
- 1/The IDX and the SEO that comes with it are genuinely good, and that is the reason people buy Sierra.
- 2/Pricing is published: $299.95 a month, Growth $599.95 for five users.
- 3/Lead routing, market reports and behavioural alerts all work out of the box.
- 4/One vendor for the site and the CRM, which is one fewer integration to maintain.
What 6Degrees does that Sierra Interactive does not
- 1/We do not sell you a website, so nothing here is priced around one.
- 2/The referral is the object: a server-set date, a window, a rule, and a fee at the end of it.
- 3/The dialer is not an add-on, because there is no dialer. What there is instead is a create-only record of every call you make elsewhere.
- 4/No setup fee, on any plan, ever.
The thing both products are arguing about
A referral has a fee, a counterparty, a deadline and a rival. That makes it an object with a state machine, not a note on a contact. Once you accept that, the only remaining question is whose database the object lives in, and the answer decides who can still read it after you stop working with that brokerage.
