CINC vs Sierra Interactive 2027: Pricing, Fit, Trade-offs

Start with the category: two bundled lead-and-CRM platforms, not two CRMs

If you are choosing between CINC and Sierra Interactive, you are not choosing where contacts get stored. Both sell lead generation, a property-search website, a CRM, and follow-up automation as one subscription, so the real decision is whether you can budget the price and whether you can live with the leads it brings in. A real estate lead-and-CRM platform is software that generates or buys buyer and seller leads, keeps them in a pipeline, and runs follow-up without someone sending each message by hand.

Neither product has been merged or discontinued in the sources we checked. CINC says it has worked with professionals since 2011, and its about page states that it "was acquired by Fidelity National Financial (FNF)," according to CINC (2026). The 2016 announcement reported that CINC had more than 1,500 customers and that the deal terms were not disclosed, according to HousingWire (2016). Sierra Interactive was acquired by ASG, a portfolio company of Alpine Investors, announced October 13, 2022, according to Willkie (2022). We found no later ownership change for either company, but both vendors should confirm current ownership in writing during procurement.

TL;DR: Choose Sierra Interactive if published starting prices and documented webhooks matter most. Choose CINC if a team-scale lead engine is worth a quoted core price and you accept that lead quality is the main risk, and get that quote in writing before you compare anything else.

Key Takeaways

• Both products are bundled lead-and-CRM platforms, so compare them on price clarity, lead quality, and integration rights rather than on contact storage.

• Sierra Interactive publishes starting prices for its two main plans, but its page gives no billing terms, user counts, or setup fees.

• CINC keeps its core plans quote-based, publishes user tiers, and prints prices only for an AI add-on and a dialer add-on.

• Third-party prices for both products disagree with the vendor pages, so the number you budget with should come from a written quote.

• Sierra documents its API key, webhook events, and webhook failure records; we could not open CINC's developer documentation, so confirm integration rights before you sign.

• CINC reviews flag lead quality as the main complaint, and Sierra's reviews are too few to judge that point, so set a lead-review check before you commit to any contract term.

How we evaluated these tools

We weighted seven criteria to match the decisions a small team actually makes, and we tied each weight to a reason. The weights are our judgment rather than vendor data, so change them if your priorities differ.

Price clarity carries the most weight because it is the only criterion a buyer can settle before the first sales call. Lead quality ranks next because it is the complaint that turns a monthly fee into wasted hours.

What each vendor publishes, side by side

This matrix keeps vendor-published facts apart from third-party reports. "Not confirmed" means we could not open the source that would settle the point.

The most useful gap in this table is the API row for CINC. Sierra publishes its API reference and webhook event names, while the cinc.io documentation address did not resolve when we tried it. The connector we could open for CINC, Pipedream's new-lead trigger for CINC, polls CINC on a timer rather than receiving pushed events, so CINC integration is a question for the sales rep, not a checkbox.

Pricing: the published numbers and the gaps

Pricing checked October 26, 2026. Only figures printed on a vendor's own pricing page count as published in this section; everything else is labeled as third-party or quote-based.

Starting price, Agents plan: $299.95 per month according to Sierra Interactive (2026). The Teams & Brokerages plan starts at $399.95 per month, and the page gives no billing terms, user counts, or setup fees, according to Sierra Interactive (2026).

Add-on for AI conversations: starting at $200 per month and a dialer add-on at $75 per month for three lines, according to CINC (2026). CINC's core plans are quote-based: each one shows a Request Pricing button rather than a number. The plans are sized by users, with Solo for 1 user, Ramp for up to 4, Pro for up to 49, and Select for 50 or more.

Third-party figures do not match the vendor pages, and no source we could open closes the gap. The Close lists a Core package at $499.95 per month for up to 5 users, with a 4.4 out of 5 overall score for Sierra, according to The Close (2024, updated 2025). The same review says extra texts and dialer minutes are billed in blocks beyond the included allowance. The Close lists CINC at $899 per month for single agents and $1,299 per month for teams, with an overall score of 4.8 out of 5, according to The Close (2024, updated 2025). Softwarefinder lists a Starter package at $359.95 per month, with a one-time $500 setup fee on monthly billing that a prepaid 12-month agreement waives, and a 4.7 overall score from only three reviews, according to Softwarefinder (2026). Those Softwarefinder figures do not match Sierra's own page, even though Softwarefinder says it pulled them from the vendor's website. Treat that gap as unresolved until a written quote names the user count, billing term, and setup fee.

Every figure in the table below is one of the figures cited in this section, so the table adds no new source.

The table below turns those figures into an illustrative four-user, 12-month view. It is arithmetic on the published numbers, not a quote.

Read the table as a floor, not a quote. Sierra's starting price is the only base price either vendor prints, and CINC's add-ons sit on top of a core price you cannot see until a rep sends one.

Here is a hypothetical four-agent team, not a customer: it receives 60 new leads a week, and one in four needs a manual contact check that takes three minutes. That is 15 checks, or 45 minutes, each week, which comes to 2,340 minutes, or about 39 hours, across 52 weeks. If the team also wants saved-search alerts tied to buyer budgets, Sierra's public API reference describes saved-search objects with dotted filter fields such as price.Max, so an operations lead can set a budget ceiling once per buyer instead of re-keying it on every lead. Those 39 hours are the number to put in front of each vendor, because it shows how much review time the platform leaves to your staff.

Lead quality is the complaint that matters most

Reviews keep returning to lead quality, and the complaint is sharpest for CINC. One reviewer on Softwarefinder wrote, "Most of the leads that come through are not really true leads." CINC independent score: 4.3 out of 5 from 82 reviews according to Softwarefinder (2025). The same reviews also describe the app as glitchy, so the risk is both the leads and the tool that delivers them.

The proposed US Tech Automations design for Sierra starts from the LeadCreated event on a webhook subscription, which Sierra's API documents. The action would check each new lead's phone and email fields, tag the lead source, and write any failed check to a shared review list. The prerequisites are an API key from Gear Icon > Integrations > Sierra Interactive, a webhook subscription pointing at a URL your team controls, and written confirmation that your plan includes API access. The human review point is a named person who clears every flagged contact before the lead counts toward follow-up targets. The output is a daily count of failed contacts by source, which gives the team evidence for the lead-quality question instead of an impression.

For CINC, the proposed design would start from a scheduled pull instead, since the only route we could confirm is a third-party connector that polls for new leads on a timer. The trigger is that poll, the action applies the same field checks and source tags, and the output is a weekly lead-quality table that tests whether the reviews' complaints hold in your market. The prerequisites are CINC authorization through the connector's OAuth flow, written confirmation that API or export access is included in the quoted plan, and a retention window long enough to compare months. The human review point is the same as above: a person decides whether a source gets more budget, and the workflow only flags.

Sierra Interactive: best fit, limits, and rollout

Sierra fits a solo agent or small team that wants a readable starting price, a CRM connected to its website, and an API a developer can reach. Its pricing page describes the Agents plan for solo agents or small teams and the Teams & Brokerages plan for growing teams that want to manage more leads and close more deals. The page lists the bundle as an IDX website, CRM, lead routing, automation, and reporting.

The limits come from reviews rather than from the vendor page. The Close calls the CRM basic, says sites have limited customization, says the platform lacks analytics and reporting, and says it is not ideal for email marketing. The same review says integrating other CRMs costs extra and that support runs through email ticketing and business-hours phone, with no 24/7 or live chat. Softwarefinder's small sample says complex issues require contacting support.

Sierra's help center says the API key is created under Gear Icon > Integrations > Sierra Interactive, that it should be shared only with trusted sources, and that disabling and re-enabling the integration issues a new key, which stops the old one working on every connected tool. The same page notes that most agents do not write custom integrations themselves, points to web developers and integration platforms, and mentions Zapier and API Nation connectors. It also says API access may depend on your subscription plan, so get that confirmed in writing. The public API reference at api.sierrainteractivedev.com documents an API key sent in a Sierra-ApiKey header, webhook subscriptions built from eventTypes and a callback URL, and event names such as LeadCreated and LeadDetailsChanged. Failed webhook deliveries are recorded with a failure count and a last-failure reason, so a named owner should review those records weekly. The reference we read did not show rate limits.

Rollout means asking Sierra for a written quote that names the user count, billing term, setup fee, cancellation notice period, and whether the API and webhooks are included. If Lofty is also on your list, our Sierra vs Lofty automation comparison covers that pairing.

CINC: best fit, limits, and rollout

CINC fits a team or brokerage that wants lead generation, IDX websites, a CRM, and team management under one contract, and that can accept a quoted core price. Its about page lists lead generation, a CRM, IDX websites, Seller Suite, automation, an AI product, communication tools, team management, integrations, mobile apps, and a referral network. The Close lists hyper-local lead generation, IDX websites, a dedicated ad and platform account manager, and seller lead capture as pros, and describes the platform as geared toward teams and top performers.

The limits are just as specific. The Close says CINC takes time to return the investment, that its cost structure may not fit newer agents, and that AI is an additional cost. Softwarefinder reviewers describe lead quality as the main complaint and report that the app has glitched.

Implementation is where the open questions sit. We could not open CINC's developer documentation, so we cannot confirm native webhook events or rate limits. The connector we could open polls CINC on a timer, posts each result to a webhook you configure, and needs OAuth authorization through its managed auth. Put three questions in writing before you sign: whether API or export access is included in the quoted plan, which add-ons the quote requires, and whether dialer minutes are included in the core price.

Where a DIY stack or a simpler tool wins

The alternative many small teams actually weigh is a stack built in Zapier, Make, or n8n, or an in-house build. Those tools can keep run histories, retries, error branches, and audit trails when they are configured, so they are not a toy. The buyer still designs and owns idempotency, so a retried webhook does not create two follow-up tasks, along with escalation paths, access controls, and maintenance every time a vendor changes its API. Sierra's help center already points small teams to prebuilt connectors, which is a fair starting point. A proposed US Tech Automations design would configure the same retry and escalation steps as parts of one workflow, but the team still needs a named owner for each step and the API access described above.

When NOT to use US Tech Automations

Skip a custom workflow and use the platform's built-in tools or a simpler CRM when three things are true. The first is that the team only needs a contact list and a calendar, which a basic CRM handles without any integration. The second is that nobody will own a weekly exception review, so an automated flag would sit unread. The third is that the vendor's plan does not include the export or API access the workflow needs, and no amount of design fixes that gap. In those cases, the platform's own automations are the simpler answer, and paying for a custom build adds cost without adding a decision the team can actually make.

Who this is for

Choose Sierra Interactive if you want starting prices you can read before a sales call, a documented API, and a CRM tied to your website, and you can accept a basic CRM with limited customization.
Red flags: you need email marketing as a core function, you need custom website design, or you need 24/7 support.

Choose CINC if you run a team or brokerage that can accept a quoted core price, you want lead generation and team management under one contract, and you have budget for the AI and dialer add-ons.
Red flags: you are a newer agent on a tight budget, you need AI included in the core price, or you cannot absorb a stretch of unqualified leads while you filter them.

Decision checklist before you sign

• Get a written quote for the exact user count, with every add-on the team will use.

• Confirm billing terms: monthly or annual, setup fee, and the cancellation notice period.

• Ask whether your plan includes API access and webhook subscriptions, and get the answer in writing.

• Ask for lead-source and lead-validity reporting for the first 30 days.

• Confirm who owns the website and in what format your data can be exported.

• Name one person to review lead exceptions in week one.

• Compare the two quotes on the same team size and the same terms, not on the starting prices alone.

Frequently asked questions

Is CINC still owned by Fidelity National Financial?

Yes, CINC's own about page says it was acquired by Fidelity National Financial, and we found no later change in the sources we checked. Confirm that ownership is unchanged in writing during procurement.

Did Sierra Interactive change owners?

Yes, ASG, a portfolio company of Alpine Investors, acquired it, as covered in the first section. We found no newer ownership change, but ask the vendor to confirm current ownership before signing.

What does Sierra Interactive cost?

Its pricing page publishes starting prices for two plans, but it does not publish billing terms, user counts, or setup fees, so the pricing section above is the only place to compare its numbers.

Can I get a fixed price from CINC?

Not from the published page: its core plans are quote-based, and only the add-ons carry printed prices. Ask for a quote that lists the core plan and every add-on together.

Does either tool have a public API?

Sierra publishes API documentation with webhook events, but its plan access may vary. For CINC, we could not open developer documentation, so ask for written confirmation of API and export access before you sign.

Should a small team skip both and build in a no-code stack?

Sometimes: a team with one owner and a simple pipeline may do better with a basic CRM and the no-code tools described above. The deciding factor is whether someone will own the review work each week.

Making the call this quarter

Sierra Interactive is the easier of the two to price and to connect, and CINC is the one to choose only if its quote fits your team and you accept the lead-quality risk that its reviews describe. Get both quotes in writing, ask for the same team size and terms, and run a lead-review check before you sign anything.
