The honest comparison between an integrated HR platform and a patchwork of point solutions is not settled by the licence price on a pricing page. It is settled by the total cost of ownership (TCO) — what the whole thing actually costs, year after year, once you add up integration, administration, data duplication and compliance risk.
The point-solution sprawl
The story is familiar. You start with payroll software. Then you add a leave tool because the spreadsheet no longer copes. Next an onboarding module, an appraisals SaaS, another for expenses, a separately purchased employee portal. Each decision is reasonable on its own.
Three years later, a 100-person company routinely runs five to eight separate HR subscriptions, each with its own vendor, contract, renewal cycle, employee repository and access policy. Nobody ever decided on this complexity: it accumulated. This is sprawl, and its cost appears on no invoice.
Luxembourg sharpens the effect. Payroll must account for tax classes (1, 1a, 2), withholding at source for the Bureau RTS at the ACD, declarations to the CCSS and automatic wage indexation — the latest +2.5% tranche took effect on 1 June 2026. A local payroll tool handles these rules; but it still has to stay in sync with the time tool, the employee portal and the contracts repository. Every boundary between two pieces of software is a place where a Luxembourg rule can slip through the cracks.
Where the real costs hide
The licence is only the visible tip. The costs that really move the needle are the ones you do not budget for up front:
- Licences and subscriptions. Usually billed per user, per month. Multiplied across several tools, the per-employee total climbs quickly, and every renewal is a separate negotiation.
- Integration. For payroll to "talk" to time tracking and the employee portal, you need connectors, syncs, sometimes custom development. This wiring is brittle: a single vendor API update can break it.
- Administration. Every tool has its own console, accounts, permissions and updates. The time HR or IT spend holding the stack together is a real cost, rarely measured.
- Data duplication. The same employee exists in five databases. An address change, a departure, a change of tax class must be propagated everywhere. Each copy is a chance for inconsistency — and an extra GDPR exposure.
"Licence pricing is what you compare before buying. Integration and duplication are what you pay every month, without ever having costed them."

To compare on sound footing, reason over three years and add up five items, not one. The method holds whatever your own figures are:
- Direct licence cost. The sum of every tool's subscription, projected over three years, allowing for expected headcount growth.
- Integration cost, one-off and recurring. Building the connectors, plus maintaining them as APIs change. An integration that "holds" demands continuous attention.
- Internal administration cost. HR and IT time spent on account, permission and incident management, multiplied by a loaded hourly rate.
- Cost of duplicated data. Double-entry and reconciliation time, plus the cost of the errors it causes (an employee paid on the wrong base, a departure poorly propagated).
- Compliance and risk cost. The effort to keep a coherent record of processing, handle data-subject rights and respond to an incident when data is scattered.
The classic mistake is to compare only the first item. That is where point solutions appear to win — and where the reasoning goes wrong.
A side-by-side comparison
The table below is qualitative: it invents no precise figures, it shows where each model concentrates its costs. Drop your own numbers into it to get your TCO.
| Cost dimension | Point solutions | Integrated platform |
|---|---|---|
| Licences | Multiple per-user subscriptions, stacked | One scope, no per-user licence with Luxapps |
| Integration | High: connectors to build and maintain | Native: modules share one foundation |
| Administration | One console per tool, permissions to replicate | One console, one access model |
| Data | Duplicated in each tool, to reconcile | One source of truth, entered once |
| Compliance | Scattered record and access, slower incident | Unified record, native audit log |
| Renewal | Several contracts, unsynced dates | One counterpart, one cycle |
The "licences" row sometimes favours point solutions. Every other row leans towards integration — and those rows carry the most weight over three years.
The compliance cost of data silos
This is the most underestimated item. In Luxembourg the employer is the GDPR controller and must maintain a record of processing activities (Article 30) covering recruitment, payroll, working time and, where relevant, health data. When those processes live in five different tools, keeping that record current becomes a permanent reconstruction exercise.
The difficulty surfaces at the worst moment. In the event of a data breach, notification to the CNPD generally falls within 72 hours. Answering an access or erasure request, or scoping an incident, means knowing where every copy of a data point lives. With silos, that map does not exist; you rebuild it under pressure. An integrated model, where each data point has a single source and a native audit log, turns that race against the clock into a simple query.
When point solutions still make sense
Integration is not a dogma. A specialised tool earns its place when a need is genuinely atypical — a very particular sector collective agreement, a bespoke operational scheme with no equivalent — and no platform covers it well. It also earns its place in transition, while you migrate.
So the real question is not "integrated or point" in the abstract, but "is this need specific enough to justify one more tool, with the wiring, administration and compliance risk that come with it?". More often than not, for a 50 to 200 employee company, the answer is no.
One more factor tips the balance: the EU AI Act. Where an HR tool uses AI for recruitment, candidate evaluation, task allocation or performance monitoring, it is classified high-risk under Annex III, and the employer as deployer carries duties around human oversight, transparency to candidates and employees, and informing worker representatives. These obligations are phasing in, with application generally expected around late 2027 — confirm exact timing with your advisor. Meeting them across several disconnected tools, each with its own AI features, is far harder than on one platform with a single access model and a native audit log.
The integrated, sovereign alternative
An integrated cloud HR platform removes most of these hidden costs at the root: a single source of truth for employees, one access model, a coherent record of processing and a native audit log. There are no longer connectors to maintain between payroll, time and the employee portal, because they share the same foundation.
Luxapps' approach adds two differences that weigh on TCO. First, the commercial model: no per-user licence, billing by the line of code per month with no upfront development fee — cost follows the value actually delivered, not headcount. Second, sovereignty: data is hosted in Luxembourg and never leaves the EU, with no dependency on a non-EU cloud provider. For an HRIS that concentrates the organisation's most sensitive data, that is not a detail.
The platform's growth shows that integration holds at scale: see how Luxapps serves a large user community.
