The verdict in three sentences
For a property developer, the website becomes profitable once it shows a live grid of available units, synced with the sales software, instead of static project pages. The 2026 budget sits between EUR 18,000 and 40,000 (about USD 19,500 to 43,000), with a 3 to 4 month timeline. Each direct lead costs EUR 20 to 45 versus EUR 60 to 150 on a listing portal, which pays back the site within months at a volume of 400 homes a year.
Why a unit grid changes sales performance
A new-build buyer wants to know three things before calling: what is still available, at what price and on which floor. When the site shows units that are already reserved, the prospect loses trust and the sales rep loses time. Syncing with the sales tool updates the status (available, on hold, reserved, sold) with no re-keying.
| Criterion | Static project pages | Synced unit grid |
|---|---|---|
| Availability updates | Manual, often weekly | Automatic, several times a day |
| Buyer filters | None or by project | Unit type, floor, orientation, price, outdoor space |
| Floor plans | Emailed on request | Downloadable after a form |
| Lead qualification | Name and phone | Target unit, budget, financing |
| Errors on sold units | Frequent | Near zero |
| Performance tracking | Overall visits | Leads per project and per unit |
Gated floor plan downloads are the strongest lever: they turn an anonymous visitor into a lead who has already picked a specific unit.
Budget and timeline by scope
| Package | Scope | 2026 price excl. tax | Timeline |
|---|---|---|---|
| Core | Corporate site, 5 to 8 projects, detailed sheets, forms | EUR 18,000 to 24,000 | 3 months |
| Connected grid | Core + synced unit grid, filters, downloadable plans | EUR 24,000 to 32,000 | 3 to 3.5 months |
| Full sales suite | Grid + buyer area, sales office booking, per-project dashboards | EUR 32,000 to 40,000 | 4 months |
The most variable item is the connection to the sales software: depending on whether the vendor offers a documented API or a plain export, the connector takes from a few days to several weeks of development. Ask your vendor before you start the tender.
Acquisition cost: portal versus direct website
| Metric | Listing portal | Developer website |
|---|---|---|
| Cost per lead | EUR 60 to 150 | EUR 20 to 45 |
| Lead exclusivity | Shared with visible competitors | Exclusive |
| Target unit data | Partial | Complete |
| Lead-to-appointment rate (estimate) | 8 to 12 % | 15 to 25 % |
| Data ownership | Platform | Developer |
Portals remain useful for awareness at project launch. The goal is to move a growing share of leads to the website.
Mini case study
Julien, sales director at a developer, sells 400 homes a year and buys about 3,000 portal leads a year at EUR 90 on average, i.e. EUR 270,000. He chooses the Connected grid package at EUR 28,000.

If 30 % of those leads move to the website at EUR 35 (media spend included), he saves 900 × EUR 55 = EUR 49,500 a year. The site pays back in under 7 months, before counting better qualification: reps receive the target unit and budget, cutting about 15 minutes from each first call.
FAQ
Can the website connect to any sales software?
Yes if the vendor provides an API or an automated export. Without an API, an hourly file sync is still possible, for an extra connector cost estimated at EUR 2,000 to 6,000.
Should unit prices be displayed?
Showing "from" prices per unit type increases the qualified lead rate. Some developers show the exact price of each unit, and the grid allows this unit by unit.
How long does it take to add a new project?
With a well-designed back office, a new project page is published in half a day. Units are imported automatically from the software.
Does the site handle off-plan sales and investors?
Yes, separate journeys for owner-occupiers and buy-to-let investors are included, with simple calculators. They represent about 10 % of the budget.
How long before results can be measured?
The first direct leads arrive in the first month. It takes 3 to 6 months to compare cost per lead with portals objectively.
