The verdict in three sentences
A developer completing around 350 homes a year across the Greater Dublin Area that tracks buyer payments, extras and snag lists in spreadsheets ties its sales team to repetitive buyer calls and lets completions slip. A custom platform linking construction progress, buyer payments, a buyer portal and snagging costs, as a 2026 order of magnitude in Ireland, 90,000 to 150,000 EUR. Delivered in 7 months, it targets 40% fewer buyer calls and a much faster snag close-out.
What spreadsheet management costs a Dublin developer
In Ireland, new-home buyers typically pay a booking deposit when reserving, a contract deposit (commonly 10% of the price, less any booking deposit) on signing, and the balance at closing, often funded by mortgage drawdown and, for eligible first-time buyers, the Help to Buy scheme. Across 6 to 10 schemes in Dublin, Kildare and Meath, that means well over 1,000 payment events a year, each needing solicitor coordination, lender paperwork and follow-ups.
On top of that come upgrade choices and extras (kitchens, flooring, wardrobes), then hundreds of snag items at handover to chase with subcontractors. The construction director and sales administrators spend their days on the phone.
| Process | Spreadsheet management | With a dedicated platform (2026 order of magnitude) |
|---|---|---|
| Issuing payment requests and closing notices | 2 to 5 days after the trigger | Same day, generated automatically |
| Tracking receipts | Monthly manual reconciliation | Real-time status per unit |
| Buyer questions | 6 to 10 calls per home during build | Buyer portal, 40% fewer calls |
| Upgrades and extras | Email threads and PDF quotes | Priced catalogue, online approval |
| Snag recording | Paper or scattered photos | App with photo, floor plan pin and assigned trade |
| Average snag close-out time | 60 to 90 days | 30 to 45 days |
Modules and platform budget
The platform is built as a custom web application with a buyer portal, a developer back office and a mobile app for site managers.
| Module | Scope | Share of budget (order of magnitude) |
|---|---|---|
| Schemes and units | Schemes, blocks, units, plans, prices, buyers | 10% |
| Milestones and payments | Booking and contract deposits, closing, reminders, solicitor workflow | 25% |
| Buyer portal | Documents, site photos, payment schedule, messaging | 20% |
| Upgrades and extras | Catalogue, pricing, e-signature, schedule impact | 15% |
| Snagging and defects period | Mobile capture, assignment, close-out, trade reminders | 20% |
| Dashboards | Receipts, delays, open snags per trade | 10% |
For around 350 homes a year, the total sits between 90,000 and 150,000 EUR depending on integrations: accounting software, existing sales CRM, e-signature and solicitor data exchange.
7-month plan
Month 1: scoping, scheme and unit data model, migration of one pilot scheme. Months 2 and 3: milestones and payments. Month 4: buyer portal. Month 5: upgrades and extras. Month 6: snagging app. Month 7: rollout to all schemes and training for sales administrators and site managers.
Two details make the difference on Irish schemes. First, the solicitor workflow: closing packs, snag sign-off and Building Control completion certificates are tracked per unit, so the sales team knows exactly what blocks each closing. Second, the defects period: after handover, buyer-reported defects flow into the same snagging module, with response times per trade measured and reported to the board.
Piloting on a scheme still in its structural phase validates the payment workflow before closings begin. Security of buyer data, ID documents and mortgage approvals, is addressed from scoping in line with GDPR and the Irish Data Protection Commission's guidance.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Ciarán, construction director of a Dublin developer, hands over 350 homes a year. Sales administrators field an average 8 calls per home during the build, 2,800 calls of 12 minutes, about 560 hours. With 40% fewer calls, the team recovers 224 hours a year.
The bigger gain is cash: on an average price of 420,000 EUR, closing 5 days earlier on each unit brings forward the balance of about 378,000 EUR. Across 350 units, the reduced time on development finance at typical 2026 rates is worth tens of thousands of euros in interest. With a 120,000 EUR platform, payback comes within the year.
