The verdict in three sentences
For an agency director in Dublin, a transaction platform at 30-80 EUR/user/month reliably covers listings, portal syndication and buyer matching. A custom build at 25,000-50,000 EUR is only justified beyond 3-4 branches or when your matching must embed proprietary logic. The decisive lever: +12 % relevant matches and -2 h/day of data entry per agent.
Transaction SaaS vs custom: what it costs in 2026
Editors bill per user, with portal syndication often extra. Custom mainly makes sense for networks. 2026 orders of magnitude for a 5-15 agent agency.
| Criterion | Transaction SaaS | Custom build |
|---|---|---|
| Entry cost | 30-80 EUR/user/month | 25,000-50,000 EUR |
| Year 1 cost (8 users) | 2,880-7,680 EUR | 28,000-56,000 EUR |
| Year 3 cumulative | 8,640-23,000 EUR | 34,000-62,000 EUR |
| Portal syndication | Often optional | Custom integrated |
| Buyer matching | Standard | Proprietary algorithm |
| Time to launch | 1-4 weeks | 3-6 months |
| Multi-branch | Per licence | Native |
Below 10 agents in a single branch, SaaS almost always wins. Custom becomes relevant for a multi-branch network with specific listing-sharing rules.
What software changes day to day
Wasted time comes from double entry (listing, portals, CRM) and manual matching. A tool that syncs everything removes these frictions.
| Task | Without integrated tool | With software | Gain |
|---|---|---|---|
| Listing entry + syndication | 45-60 min/property | 10-15 min | -70 % |
| Buyer matching | Manual, random | Automatic scored | +12 % relevant |
| Buyer follow-ups | Missed 1 in 3 | Scheduled | +8 % conversions |
| Listing reporting | 2-3 h/week | Real time | ~1,200 EUR/month |
| Daily entry/agent | 2-3 h | 0.5-1 h | -2 h/day |
In an 8-agent agency, recovering 2 h/day is 16 team hours/day — the equivalent of 2 agents freed for prospecting and viewings.

Two mistakes recur among Dublin agency directors in 2026. First: underestimating the real cost of syndication. Transaction software does not include portal subscriptions (Daft, MyHome, and similar), which often run 400-1,200 EUR/month depending on area and listing volume. Comparing a SaaS at 40 EUR/user without factoring in this line item skews the whole budget. Second mistake: going custom too early. For an independent single-branch agency, a 30,000-50,000 EUR build almost never returns against a mature SaaS that already covers listings, matching and syndication. Custom only becomes relevant from 3-4 branches with proprietary listing-sharing and commission rules, or when buyer data becomes an asset to exploit (scoring, smart follow-up, automated sourcing). A third point deserves attention: data migration. Moving a 120-listing portfolio and buyer history from an old tool to a new one costs 2,000-6,000 EUR in services and 2 to 4 weeks; budget it from the start to avoid nasty surprises and a costly transitional double entry.
Mini case study
Marc runs a transaction agency in Dublin: 8 agents, 120 listings, average fee 9,500 EUR. Each agent loses 2 h/day on entry and manual matching, at 28 EUR/loaded hour, or 8 × 2 × 28 × 21 = 9,408 EUR/month of unproductive time. A full transaction SaaS at 65 EUR/user/month (6,240 EUR/year) that recovers even half of this pays for itself in under a month. Add +12 % relevant matches: on 40 sales/year, 2-3 extra sales represent 19,000-28,500 EUR in fees.
FAQ
Do I need custom for a single branch? Rarely. A SaaS at 30-80 EUR/user/month covers 90 % of an independent agency's needs. Custom is justified mainly beyond 3-4 branches.
How much does portal syndication cost? Depending on the editor, multi-portal syndication is included or billed 20-50 EUR/month extra. Portals have their own subscription, separate from the software.
How long for a custom build? Between 3 and 6 months for listings + syndication + matching + CRM, with a V1 in 8-10 weeks.
Is automatic matching reliable? Yes, when buyer criteria are well captured: 2026 feedback shows +12 % relevant matches and faster reaction to new listings.
What realistic time saving per agent? On average 2 h/day recovered on entry and follow-ups — the equivalent of one extra agent per four.
