The short version

  • TenantSync is an Irish-built platform purpose-made for RTB compliance automation (Form 1 draft-to-finalise, the national rent cap, Part 4 tracking) and Open Banking rent reconciliation, with included landlord & tenant portals, native iOS/Android apps, and CSV/competitor import.
  • Acquaint CRM (by UK vendor Bright Logic, with an Irish presence at acquaint.ie) is a general estate-and-letting agency CRM — broad rather than deep. It spans residential and commercial sales & lettings, client accounting, a diary, marketing and website/portal feeds, but does not publicly document Irish RTB or rent-cap automation.
  • Pick on the job you most need done: automated Irish lettings compliance and bank reconciliation across many tenancies points to TenantSync; a single system that also handles property sales and double-entry client accounting points to Acquaint.

No tool wins on every axis, and any comparison that pretends otherwise isn't worth your time. Below is the honest version — including the parts where Acquaint is the stronger choice.

Quick note on spelling

The product is officially Acquaint (with a "c"). It's so often typed as "Aquaint" that we've used both here — it's the same software either way, so if you searched for an "Aquaint CRM alternative," you're in the right place.

Why Irish agents start looking for an Acquaint alternative

Agencies rarely go shopping because their current system is bad. They go shopping because the job changed. In 2026, three things changed at once for Irish letting agents:

  • Compliance became a daily, portfolio-wide task. Annual RTB registration (mandatory for every tenancy), Part 4 cycles, and the post-March-2026 rent rules mean a missed deadline isn't just a fine — it's a professional-liability problem and a route to losing a landlord client.
  • Rent maths got harder. The national rent cap replaced Rent Pressure Zones, and the inflation measure changed (more on that below). Getting a rent review wrong now is easy, and an invalid review can be unwound.
  • Manual reconciliation stopped scaling. Matching rent to the right tenancy across multiple client bank accounts, by hand, every week, is where agency hours quietly disappear.

On top of that, some agencies tell us they're re-evaluating Windows-installed software in favour of browser-native, mobile-first tools their team can use on a viewing or from home. So the question isn't "Acquaint or not?" — it's "which platform does the 2026 version of my job best?" That depends on which of these problems hurts most.

What Acquaint CRM is — and what it covers

Acquaint CRM is a general property CRM for estate and letting agents, developed by Bright Logic Ltd, a UK software company based in Wallingford, Oxfordshire. It serves both the UK and Ireland, with an Irish-facing brand at acquaint.ie, where the vendor states it supports "over 250 agency offices" across Ireland (a self-reported figure we can't independently verify). Its main characteristic is breadth — it spans sales and lettings rather than going deep on any one area.

What Acquaint covers (per acquaintcrm.co.uk & acquaint.ie)

  • Sales and lettings CRM. Residential and commercial sales & lettings, contact/applicant management, and a "Match & Market" function to pair properties with applicants.
  • Client accounting. Double-entry accounts that produce invoices, statements and receipts, collect and process rent, and track deposits — with controls the vendor says are designed to meet Irish client-accounting rules.
  • Property management & maintenance. Work orders, gas safety certificates, utility suppliers and meter readings, and inspections.
  • Diary, marketing & comms. An office diary with appointment confirmations by email and SMS, plus mail-merge letters, emails and SMS messaging.
  • Websites & portal feeds. In-house agency websites and a portal-uploading service — in Ireland, listings can feed to your website, MyHome.ie, Daft.ie, and social channels.

So if your agency needs a single system spanning both sales and lettings, Acquaint can cover that. The trade-off is that the things an Irish lettings team now lives and dies by — RTB registration, the national rent cap, Open Banking reconciliation and tenant portals — aren't part of that picture (more on that below).

Two practical caveats worth knowing before you compare. First, Acquaint is historically a Windows-based application (it requires Microsoft Windows and runs on Microsoft SQL Server, hosted on-premises or in an off-site data centre), with a companion Acquaint Anywhere mobile app and a newer browser-based Acquaint Web — so confirm which experience your team would actually use day to day. Second, its public review base is thin (for example, a single review on G2 at the time of writing), so there isn't a large body of independent feedback to lean on.

Where TenantSync fits

TenantSync comes at the same market from a different angle. Instead of starting from a broad sales-and-lettings CRM, it starts from the two things Irish letting agents now spend the most anxious time on: RTB compliance and getting rent matched and reconciled.

It's a newer platform (and a smaller company — we'll be upfront about that rather than invent customer numbers), built specifically for Irish residential tenancies law.

TenantSync's core strengths

  • RTB Form 1 draft-to-finalise — pre-fill from the lease, validate, preview, finalise to a signed PDF; status advances automatically.
  • National rent-cap calculator — computes the maximum legal rent under the post-March-2026 rules and shows the rule and figure it used, with a disclaimer, so you stay audit-ready.
  • Compliance lifecycle — the 30-day registration deadline is auto-computed from tenancy start; annual renewals, Part 4 eligibility, rent-review windows and notices of termination are tracked, with reminders.
  • Open Banking reconciliation (PSD2) — connect the bank account and incoming rent auto-matches to the right tenancy; arrears surface the day they happen.
  • Included landlord & tenant portals, native iOS/Android apps, and CSV/competitor import — so the move doesn't mean re-keying your portfolio, and your clients get self-service access.

Where TenantSync deliberately does not compete is full estate-agency sales progression, in-house website building, and broad sales-portal syndication — that's Acquaint's territory, and we'll flag it plainly throughout.

Acquaint CRM vs TenantSync: an honest feature comparison

Where we can verify an Acquaint capability from public sources, we've stated it. Where a capability isn't publicly documented, we've said "not publicly documented" or "check with provider" rather than claim it's missing — you should confirm anything decision-critical directly with each vendor.

Capability TenantSync Acquaint CRM

Client accounting Invoicing, billing, arrears & aging — not a full double-entry ledger Yes — double-entry client accounting
Agency website building & multi-portal syndication Not offered Yes — in-house websites + portal-uploading service

Read down that table and the split is clear. TenantSync leans into depth on Irish lettings compliance and bank-feed reconciliation, with portals and mobile included; Acquaint is a general agency CRM that also covers sales and client accounting. For a lettings-led agency where RTB registrations, the national rent cap and rent reconciliation are the daily job, TenantSync is built around exactly those tasks.

Pricing compared (as published, June 2026)

The two products are priced on completely different models, so compare carefully rather than just on the headline number.

Acquaint does not publish a clear, self-serve price list. It advertises no setup fees, a rolling monthly contract and in-house support, and prices on a per-licence (per-user) basis plus a hosting charge. Figures that circulate in third-party listings — around €44 + VAT per licence per month plus roughly €25 + VAT per month for cloud hosting in Ireland — are not confirmed official pricing, so treat them as indicative and request a quote. TenantSync, by contrast, uses all-in portfolio tiers with portals included.

Plan / model Price Scope
Acquaint CRM (indicative, IE) ~€44 + VAT / licence / month (reported, unconfirmed) Per user; no setup fee, rolling monthly
Acquaint — cloud hosting ~€25 + VAT / month (reported) Off-site data-centre hosting add-on
TenantSync — Starter €20 / month Up to 10 properties (small-landlord tier)
TenantSync — Standard €99 / month Up to 100 properties; 1 bank (Open Banking)
TenantSync — Growth ⭐ €149 / month Up to 200 properties; 3 banks; RTB bulk compliance
TenantSync — Premium €199 / month Up to 300 properties; 5 banks; account manager
TenantSync — Enterprise Custom Multi-branch / white-glove

How to read this fairly

The models aren't directly comparable. Acquaint charges per user, so cost scales with team size, and it bundles capabilities TenantSync doesn't try to replicate (sales CRM, websites, double-entry client accounting). TenantSync charges per portfolio size, with portals and the mobile apps included and no per-user fee — which tends to suit a lettings-led team managing many tenancies. The honest comparison is "cost per job you actually need done," not list price alone. TenantSync also offers a 14-day free trial. Always confirm current pricing on each provider's own site.

Why March 2026 raised the stakes for every agency

This is the context that makes the software choice urgent. On 1 March 2026, Ireland's rental rules changed materially, and the changes touch every tenancy an agent manages.

What changed on 1 March 2026

  • National rent control replaced Rent Pressure Zones. A single national system now applies to all private tenancies. Rent can be increased once a year by a maximum of 2%, or by inflation if inflation is lower.
  • The inflation measure changed. The cap is now measured by the Consumer Price Index (CPI), not the HICP that applied under the old RPZ regime — for all tenancies, new and existing.
  • 6-year Tenancies of Minimum Duration (TMD). New tenancies created from 1 March 2026 run in rolling 6-year cycles.
  • Small vs large landlords. A "small" landlord has three or fewer tenancies; a "large" landlord has four or more. Large landlords can no longer use no-fault terminations; small landlords can in limited cases but generally can't reset the rent until the 6-year cycle ends.
  • 90-day written notice for rent reviews still applies.

For an agent, the practical upshot is blunt: you now have to apply the national cap correctly to every client tenancy, with the right index, on the right schedule, with valid notice. That's a calculation and tracking problem at portfolio scale — and it's precisely the problem TenantSync's rent-cap calculator and compliance dashboard were built to remove. Whichever tool you choose, make sure it keeps pace with the 2026 rules rather than the old RPZ/HICP ones, and that it can produce the evidence the RTB now expects when you justify a rent.

Who should switch — and who should stay on Acquaint

Here's the part most "alternative" pages skip. Switching isn't free — it costs time and change-management — so only do it if the fit is genuinely better.

TenantSync is likely the better fit if…

  • You're a lettings-led agency or property manager, and your biggest daily pain is RTB compliance across many landlord clients — registrations, renewals, Part 4, and getting rent reviews right under the new national cap.
  • You want Open Banking reconciliation so rent auto-matches to the right tenancy and arrears surface immediately, instead of manual statement-matching.
  • You want landlord and tenant portals included, plus a modern browser-native web + native mobile experience your team can use on the move.
  • You'd rather pay per portfolio size than per user, and want a low-friction switch with CSV/competitor import and done-with-you onboarding.

Acquaint may remain the better fit if…

  • Your agency does both sales and lettings and you want a single CRM that handles sales progression as well as lettings.
  • You rely on in-house double-entry client accounting and want it native in the same system.
  • You want your agency website and broad sales-portal syndication bundled with the CRM from one vendor.
  • You prefer a long-established product with in-house phone support and a large existing Irish user base, and you're comfortable with a Windows-based deployment.

A useful test: list the five things your agency does most often, then ask each vendor to show you those five — live — on your own data during a trial or demo. The right answer falls out quickly. Many agencies also run TenantSync alongside a sales CRM, using it specifically for the RTB-compliance and rent-reconciliation jobs.

How migrating off Acquaint actually works

The number one reason agencies stay on a tool they've outgrown is the fear of a painful migration — losing history, re-keying tenancies, breaking compliance dates. TenantSync is built to remove that fear.

The migration path

  • Export & import. Export your properties, tenancies, leases and rent details from Acquaint, and import via CSV/spreadsheet — TenantSync also supports direct imports from systems like Letman, so the mapping is familiar.
  • RTB date validation. Registration and renewal dates are checked so nothing falls through during the move.
  • First reconciliation in session. Connect a bank account and watch recent rent match to the right tenancies.
  • Done-with-you onboarding. You're not handed a blank screen — the import and your first real Form 1 can be done together.

What TenantSync does for Irish lettings agencies

TenantSync is built around Irish residential tenancies law — not adapted from a UK or US product. Every capability below is aimed at an agency managing tenancies across multiple landlord clients.

📋

RTB Form 1, draft-to-finalise

Pre-fill the registration from the lease, validate it, preview it in the browser, then finalise to a signed PDF. The 30-day deadline is computed from the tenancy start date and tracked automatically.

📐

National rent-cap calculator

Works out the maximum legal increase under the post-March-2026 rules — 2% or inflation, whichever is lower — and shows the rule and figure it applied, so a rent review is defensible.

🏦

Open Banking reconciliation

Connect the agency or landlord account (AIB, Bank of Ireland, PTSB, EBS, Revolut, N26, Wise via PSD2) and incoming rent auto-matches to the right tenancy. Arrears surface the day they happen. Credentials stay on the bank's screen.

🗓️

Compliance dashboard

Registration, renewal, rent review, Part 4 and notice-of-termination obligations tracked per tenancy and colour-coded compliant / upcoming / overdue — across your whole book of clients.

🧾

Invoicing & arrears

Recurring monthly invoices, management- and contractor-fee invoicing, PDF generation, an aging report and automated reminders (before due, on due, and overdue) so collection doesn't depend on someone remembering.

👥

Landlord & tenant portals

Included for every client — landlords see portfolio, compliance and rent status; tenants see their lease, pay history and can raise maintenance requests. Plus native iOS & Android apps.

📥

Daft & MyHome inquiry capture

Daft.ie and MyHome.ie enquiry emails are parsed into a single lead inbox with applications and attachments, so the lettings funnel from enquiry to tenancy stays in one place.

🏢

Multi-branch & team

Agencies, branches and role-based access for your team, with per-client reporting and an enterprise tier for multi-branch operations and white-glove onboarding.

Put your agency's real workflow to the test

Import your portfolio, finalise one real Form 1, and reconcile last month's rent — in a single session. That's the fastest way to know if TenantSync fits.

Frequently asked questions

What is the best Acquaint CRM alternative for Irish letting agents in 2026?

It depends on the job you most need done. TenantSync is an Irish-built platform focused on RTB compliance automation (Form 1 draft-to-finalise, the national rent cap, Part 4 tracking) and Open Banking rent reconciliation, with included landlord and tenant portals and native mobile apps. Acquaint CRM, by UK vendor Bright Logic, is a broad all-in-one estate-and-letting agency CRM that also covers residential and commercial sales, client accounting, a diary, marketing and website/portal feeds. If your agency does both sales and lettings and wants one system for everything, Acquaint's breadth is a strength; if your daily pain is Irish lettings compliance and rent reconciliation, TenantSync is built around exactly that.

Is it spelled Acquaint or Aquaint?

The product is officially spelled Acquaint CRM (with a "c"), made by Bright Logic Ltd and marketed in Ireland at acquaint.ie. It is very commonly searched as "Aquaint," so if you arrived looking for an "Aquaint CRM alternative," you are in the right place — it is the same software.

Does Acquaint CRM handle RTB registration and the Irish rent cap?

Acquaint markets Daft.ie and MyHome.ie portal feeds and says it has controls to meet Irish client-accounting rules, but it does not publicly document RTB Form 1 registration, the Rent Pressure Zone / post-March-2026 national rent-cap calculation, or built-in tenant and landlord portals. Confirm anything decision-critical with Acquaint directly. RTB Form 1, the national rent cap and Part 4 tracking are what TenantSync is built around.

Does TenantSync replace an estate-agency sales CRM?

No — be deliberate here. TenantSync is focused on residential lettings, RTB compliance and rent automation. It does not provide estate-agency sales progression, in-house agency website building, or syndication to dozens of sales portals the way a full estate-agency CRM such as Acquaint does. If your agency's centre of gravity is property sales, evaluate that requirement carefully. Many lettings-led agencies move for the compliance and reconciliation automation, and some run TenantSync alongside a separate sales CRM.

How much does Acquaint CRM cost compared with TenantSync?

Acquaint does not publish a clear self-serve price list; it advertises no setup fees, a rolling monthly contract and in-house support, and quotes are per licence (per user) plus a hosting charge. Figures around €44 + VAT per licence per month plus roughly €25 + VAT per month for cloud hosting appear in third-party listings rather than as confirmed official pricing, so request a quote. TenantSync uses all-in portfolio tiers: Standard €99 (up to 100 properties), Growth €149 (up to 200) and Premium €199 (up to 300), with a €20 Starter for up to 10 properties and custom Enterprise pricing; landlord and tenant portals are included. Always confirm current pricing on each provider's own site.

Can I migrate my data from Acquaint to TenantSync?

Yes. TenantSync supports CSV and spreadsheet import for properties, tenancies, leases and rent details, plus direct imports from systems like Letman, and offers done-with-you onboarding to validate RTB dates and run your first reconciliation. Export your data from Acquaint and TenantSync's team can help map it across so you don't re-key your portfolio.

How does the March 2026 national rent cap affect letting agents?

Since 1 March 2026, Rent Pressure Zones have been replaced by a national system of rent control: rent can rise at most once a year by 2%, or by inflation if inflation is lower. The inflation measure changed from the HICP to the Consumer Price Index (CPI) for all tenancies. New tenancies from that date are also 6-year Tenancies of Minimum Duration, with different rules for small landlords (three or fewer tenancies) and large landlords (four or more). Agents now apply the national cap to every client tenancy and keep the 90-day written-notice rule — exactly the kind of calculation TenantSync automates.
