How we keep it short

A modern stack changes the maths

Large enterprise housing systems are often implemented as multi-year programmes. Rentalize was built cloud-native, with a migration team that maps, de-duplicates and checks your data before import, and reusable accelerators for HAP, RTB, the 2026 rent cap, LAAPS and cost rental applicant intake. That is how we set a 6 to 10 week target go-live, sized after a Discovery week.

Questions to ask any vendor
Put these to every shortlisted supplier
What is the written go-live timeline, and what triggers a change order?
Who maps and checks the data, and how are errors caught before import?
Is the method set up for Irish and UK housing schemes such as HAP and the RTB?
Is it configuration or custom code, and what does that mean for upgrades?
Is delivery remote or on-site, and how are consultant days billed?

The Methodology

Six phases, fixed scope, weekly checkpoints

Every implementation runs the same playbook, sized to your portfolio. Each phase has clear entry and exit criteria, signed-off deliverables, and a RAID log shared with your sponsor.

1
Discover
Week 1
Workshops, system audit, data sample, scope and success criteria signed off.
2
Design
Weeks 1 to 2
Configuration plan, integrations, security, data quality rules, RACI.
3
Migrate
Weeks 2 to 6
Extract, cleanse, map, load. Reconcile against source. Iterate.
4
Train
Weeks 5 to 8
Role-based training, sandbox UAT, train-the-trainer, signed test scripts.
5
Go-Live
Week 8 to 10
Cutover plan, rollback rehearsal, go / no-go decision, hyper-care kicks in.
6
Hyper-care
Weeks 10 to 14
Daily standups, fast-track tickets, then handover to the support team.
Example 10-week Plan

What a Rentalize go-live looks like

An example 10-week schedule for a 220-unit AHB. Workstreams overlap intentionally so you go live in week 10, hyper-care closes by week 14, and your team is fully self-sufficient.

Data Migration

Get clean data out of your current system without a dedicated army

We work from whatever your current system can export: MRI exports, Excel sheets, Access databases, even SQL dumps from custom-built systems. Our migration team maps, de-duplicates and checks your data before import, and your team signs off the result.

  • Column mapping from your source files, checked by our migration team
  • Rows that fail validation listed in a downloadable error report
  • Bulk import of documents such as certificates, leases and deposit records
  • Reconciliation reports comparing source and target balances line by line
  • Re-runnable pipeline so we can iterate against fresher source extracts

Data Quality Scorecard

You see the state of your data before we go anywhere near production

Within the first two weeks we publish a data quality scorecard. Every category is rated against the rules we agree in Discover. You decide what gets fixed at source, what gets cleansed in flight, and what is acceptable to migrate as-is.

Illustrative sample scorecard. Your own scores come from your data in Discover.

Project Management

Run by a named project manager, not by a Slack channel

Every Rentalize implementation has a named project manager who owns the plan, the RAID log and change control, and our head of product and implementations is PMP certified. Public sector and enterprise customers get an additional governance layer with weekly steering committees and a written RAID log.

Governance and reporting

Weekly steering committees, monthly executive reports, RAID log, milestone tracker, and a written status pack signed off by both sides.

Joint delivery model

We work with your project team, not around it. Shared Jira board, shared Confluence space, shared Slack or Teams channel, shared accountability.

Fixed scope, fixed price

We size the engagement after Discovery and commit to a price. Change requests are visible, costed, and approved by your sponsor before work starts.

Your Delivery Team

A team that already knows Irish housing

You do not break in a generic SI. The people delivering your project have run Meath County Council's affordable purchase portal since 2022, and Rentalize Select has processed more than 200,000 applications with zero downtime through intake peaks, including a single week of 4,600. Domain expertise, not just software expertise.

  • 5,000+ units under management across our customer base
  • 200,000+ applications processed with zero downtime, peaking at 4,600 in one week
  • In production with a local authority since 2022
  • Live with HAP tenancies, RTB compliance, the 2026 rent cap and affordable purchase schemes

Go-Live Decision

A clear, written go / no-go criteria. Decided together.

Two weeks before cutover we publish the go / no-go scorecard. Every item is green, amber, or red against the rules we agreed in Design. Going live is a joint decision between your sponsor and ours, on the record.

Green: Go
  • Data quality score above 90
  • All P1 and P2 UAT defects closed
  • Cutover rehearsal passed end to end
  • Trained users sign off readiness
  • Hyper-care cover confirmed
Amber: Go with conditions
  • Data quality 80 to 90 with mitigation plan
  • Open P3 defects with workarounds
  • Partial training, top-up scheduled
  • Manual fallback for one process
  • Sponsor accepts written risks
Red: No-go, replan
  • Data quality below 80
  • Open P1 or P2 defects
  • Cutover rehearsal failed
  • Untrained critical roles
  • Regulatory blocker unresolved
Frequently Asked

Implementation questions our customers ask

Our target go-live for a fixed scope is 6 to 10 weeks, set after a Discovery week. Large enterprise housing systems are often implemented as multi-year programmes, so ask any vendor you are comparing for a written plan for the same scope. Our timeline comes from cloud-native architecture, a dedicated migration team, and pre-built accelerators for HAP, RTB, the 2026 rent cap, LAAPS and cost rental applicant intake.
We work from whatever your current system can export: MRI and Yardi exports, Civica and Aareon extracts, custom Access databases, raw SQL Server dumps, and Excel workbooks with merged cells. If we can read the bytes, we can map the data.
A named Rentalize project manager owns delivery end to end. We work with your project team on a shared Jira board, shared Confluence, and a shared Slack or Teams channel. Steering committee, RAID log, and status reports are written and signed off weekly.
Fixed scope, fixed price after a one-week paid Discovery. Change requests are visible, costed, and only proceed with sponsor approval. We do not bill consultants by the day for things you have already paid us to deliver.
A 4 to 6 week hyper-care window with daily standups, a fast-track ticket queue, and the implementation team still in the loop. After hyper-care, your named CSM and the support team take over with full SLAs. See our Support page for details.
Yes. We have been in production with an Irish local authority since 2022, and our governance, security, and contractual model is designed for OJEU and public procurement. Data is stored in the EU, and ISO 27001 certification is in progress.
