Editorial verdict

How to choose between them

Follow Up Boss assumes you bring a website. Sierra assumes the website is the product.

If your stack already includes an IDX site and lead sources, FUB’s routing, action plans, and per-user price are the cleaner CRM story. If you are tired of paying a site vendor and a CRM vendor — and you want behavior from property views inside the same system — Sierra’s published packages are the cleaner all-in-one story.

Neither gives you native WhatsApp. Neither runs a rent roll like AppFolio. The duel is hub flexibility versus native IDX + CRM.

Score by criterion

In green, who wins the criterion. The overall score uses real estate weights: inventory and proposal and native messaging weigh more.

CriterionSierra InteractiveFollow Up Boss

Inventory and proposal1.3×
Property cards or unit inventory, matching to the lead, and a commercial proposal without a parallel spreadsheet.
8.8
6.0
Mortgage credit0.7×
Simulate a purchase mortgage (or a builder’s loan pipeline) without sending the client to another portal. Tenant screening is not mortgage credit.
3.2
2.5
Leasing and post-sale1.2×
Lease, collections, owner statements, or post-close assistance. A “won” stage in the funnel is not portfolio administration.
7.0
5.5
Native messaging1.3×
Native SMS or messaging inbox on the lead card, with team history. WhatsApp Business API also counts. Marketplace apps, extensions, and website buttons do not.
8.6
8.8
Price and transparency0.9×
Public plan in USD, trial, and what sits outside the monthly fee. A mandatory add-on for day-to-day work lowers the score.

Learning curve0.8×
English UI, listing and showing vocabulary, and time until an agent can work without a long implementation project.
