What Should a 25-Agent Real Estate Brokerage Actually Pay for Software?

In most of the businesses we look at, "software spend" and "advertising spend" are two separate line items. In real estate brokerage, they collapse into one: Zillow Premier Agent, at $2,000/mo, costs more than any CRM, transaction platform, or accounting tool in the entire stack — because it's not software, it's pay-for-placement advertising billed like a SaaS subscription. That's exactly why generic "software cost" benchmarks are useless here. Half the bill is lead-buying, not tooling, and the two behave completely differently when you're deciding what to cut.

Here's the real breakdown, pillar by pillar, for a 25-agent brokerage — roughly the size where a brokerage has outgrown a single owner-operator's spreadsheet but hasn't yet hit the volume that justifies BoomTown's dedicated lead-qualification team.

Sales & Marketing: $1,865-3,565/mo

Zillow Premier Agent runs $2,000/mo for pay-for-placement ads on Zillow and Trulia listing pages, routing buyer inquiries straight to whichever agent currently holds that zip code's placement — priced like paid search, not like software, which is why it's the largest single line item most brokerages carry. Realtor.com Connections Plus is the direct alternative at $1,200/mo, selling a zip-code-exclusive lead subscription instead of an open-bid placement. Running both is the single most common overspend in this vertical: $3,200/mo in combined portal advertising, with most brokerages unable to say which channel actually produced last quarter's closings. On top of whichever portal you pick, your CRM handles routing and nurture — Follow Up Boss ($600/mo, 3-150 agents) is the lean pipeline-only option, kvCORE ($750/mo, 5-200 agents) adds a built-in IDX website, and BoomTown ($1,500/mo, 10-300 agents) adds a dedicated inside-sales-agent team that pre-qualifies leads before an agent calls. Mailchimp rounds out the pillar at $65/mo for listing announcements and past-client re-engagement email.

Core Operations: $1,000-1,050/mo

Transaction management is a straight either/or, not a stack. Dotloop ($500/mo) and SkySlope ($450/mo) both cover e-signature, document storage, and compliance checklists for the same job — paying for both, which happens whenever agents from a prior brokerage keep defaulting to whichever platform they learned first, is $950/mo for one function done twice. ShowingTime adds $250/mo for automated showing scheduling and post-showing feedback collection between listing agents, buyer agents, and sellers; skip it and a transaction coordinator ends up coordinating showings by phone and text — hours that never show up as a software line item but show up everywhere else. Matterport adds $300/mo for 3D virtual tours and floor plans, a real differentiator against agents still posting static photos only, and increasingly expected on higher-priced inventory.

Finance: $690/mo

QuickBooks Online ($90/mo) is the general ledger, covering brokerage operating expenses and — critically for real estate — trust/escrow reconciliation, which is a state compliance requirement, not a nice-to-have. Gusto ($200/mo) runs payroll for W-2 staff like transaction coordinators and marketing help, alongside 1099 commission tracking for agents; misclassifying an agent's commission as W-2 wages, or the reverse, is a real and expensive mistake to unwind at tax time. Brokermint ($400/mo) automates commission calculation and split disbursement — the category brokerages most often underinvest in, running splits through a shared spreadsheet until a calculation error triggers a dispute with an agent over a five-figure closing check.

Admin & Security: $430/mo

Google Workspace Business Standard ($170/mo) covers email and shared calendars for staff and agents. 1Password Business ($95/mo) gives agents shared vaults instead of a single MLS login passed around by text — a real finding in brokerages that never centralized credentials. DocuSign ($80/mo) handles general e-signature for HR, vendor, and independent-contractor agreements outside the deal-specific transaction platform. Huntress Managed EDR ($85/mo) puts 24/7 human-monitored threat detection on office PCs handling client financial and closing documents — worth naming specifically in real estate, where wire-fraud attempts targeting closing funds are a well-known industry risk, and an unmonitored endpoint is exactly the kind of gap that lets a spoofed wiring-instructions email through.

What this adds up to

Add it up and a genuinely optimized stack for a 25-agent brokerage lands in the $3,985-5,735/mo range depending on which CRM and transaction platform you pick — but the representative brokerage in our data pays $9,800/mo for the same functional coverage. The gap almost never comes from needing more capability; it comes from three repeatable patterns.
