IDX and MLS Integration: The Question to Ask Before the Price

MLS integration is granted board by board, not nationally

There is no single MLS. Access to listing data is granted by each individual multiple listing service to approved vendors under that board's own rules, which is why "MLS integration" on a pricing page tells you a capability exists and nothing at all about whether it reaches you.

This is the single most important question to ask a vendor, and the one most likely to be answered with a brochure. Top Producer is the only product on our comparison that publishes a number — its pricing page advertises MLS integration with 320+ boards — and even that is a count, not a list.

IDX and MLS are not the same purchase

An MLS feed puts listing data inside your CRM; IDX puts listing data on your public website. They are often sold together and they are separate things, with separate rules and sometimes separate fees from your board.

• The MLS feed populates a property record, keeps status current, and lets you build market reports. It is an internal capability.
• IDX display shows your board's listings to the public on your site, under display rules the board sets — attribution, refresh frequency and what may be shown.
• The board's own fee. Some boards charge for data access or IDX feeds independently of what the software vendor charges. That bill arrives from your board, not from the vendor, and it is the one people do not budget for.
• Lofty and BoldTrail sell the site and the CRM together, which is part of why neither publishes a price — the bill depends on agent count and what is attached.

The four questions to put in an email

Ask these before a demo rather than after, and ask for the answers in writing. A vendor that cannot answer the first one by name is not a candidate, whatever its price.

1. Is my board — named in full — on your current integration list, live today?
2. What does the IDX display on my own website cost in addition to the CRM subscription, and is that per site or per agent?
3. Does my board charge its own data-access or IDX fee, and if so who pays it?
4. If we leave, what happens to the listing data and the contact records — what can be exported, in what format, and at what cost?

What it is reasonable to expect it to cost

There is no published price for MLS integration as a line item on any product we read, which is itself the finding. What exists instead is a plan that includes it: Top Producer Pro at $179 per user a month is the cheapest published price on our comparison for a plan that advertises MLS integration as part of the tier.

Everything cheaper on the industry side either does not advertise a board count or does not publish a price at all. On the general side there is no MLS connection at any tier — which is the one genuine dividing line between the two halves of the market.

When you do not need it

Most agents do not need listing data inside their CRM, and saying so is not controversial. If you work a sphere, list a handful of properties a year and search the MLS in the MLS, a feed into your CRM duplicates a tool you already use fluently.

The case for it is volume and market reports: an agent sending branded market updates to a farm, or a team whose property records need to stay current without anyone typing. If neither describes you, a general CRM at $14 a seat a month is the better purchase and the money is better spent elsewhere.

What a feed actually delivers

A data feed from your board delivers listing records on a schedule, not a live window into the MLS, and the schedule is part of what the board grants. That is the practical difference between a CRM that shows listing data and the MLS itself, and it matters most in a fast market.

• Refresh frequency. How often the feed updates is set by the board, and stale status is the complaint that follows.
• Field coverage. Not every field in the MLS necessarily comes through, and the ones that do not are usually the ones you wanted for a report.
• Display rules. What may be shown publicly, with what attribution, is the board's decision and is enforceable against you rather than against the vendor.
• Territory. A feed covers the board that granted it. Agents working across two board areas need two arrangements, and should say so on the first call.

The order to do this in

Start with your board, not with the software. Which vendors your board already supports is a far shorter list than which vendors claim MLS integration, and it is knowable in one phone call to a person whose job is to answer it.

1. Call your board and ask which CRM and IDX vendors currently hold an approved feed.
2. Ask what the board itself charges for data access and for an IDX feed, and whether that is billed to you or to the vendor.
3. Take that list to the vendors and ask each to confirm in writing that your board is live today, not in progress.
4. Only then compare prices — the shortlist will already be much shorter than the one you would have built from marketing pages.

Who this genuinely changes the answer for

Two kinds of agent should treat MLS integration as the deciding factor rather than a feature. Everyone else should treat it as a nice-to-have and buy on price and fit.

The first is the agent who farms — sending branded market updates to a defined area on a schedule. Those reports are built from listing data, and building them by hand is the work the software is replacing. Top Producer's Market Snapshot is the clearest example of a product sold on exactly that job, on a Pro plan at $179 per user a month.

The second is the team whose property records must stay current without anyone typing. Above a certain volume, manual status updates stop happening and a pipeline that lies is worse than no pipeline — at which point the feed is not a convenience, it is what makes the system trustworthy.
