Your sales team uses a shared spreadsheet, accounting runs on software installed five years ago, and customer service juggles between three mobile applications. When it comes time to streamline, the question arises: should you choose custom software, an integrated package, or a specialized application? The choice depends less on the size of the company than on the precise nature of the tasks to be covered and the regulatory constraints that now weigh on certain tools.
AI Compliance and Solution Choice: What the AI Act Changes in 2026
Cost, usability, and feature richness remain important selection criteria. But an additional parameter has now emerged: the regulatory compliance of tools incorporating artificial intelligence.
Since February 2, 2025, the European AI Act requires companies to inventory their AI uses and analyze their risk level. Recruitment software that filters applications, an HR package that evaluates performance, a decision support application: all these systems fall within the scope.
Before signing with a vendor, you must ask for a precise qualification of the system (low, high, or prohibited risk) and a compliance roadmap. Deadlines are not uniform depending on the type of system, complicating the comparison between competing solutions. You can discover Tech Planete’s articles that detail these technical distinctions between categories of tools.
Ignoring this regulatory aspect exposes the company to sanctions, as well as to technical lock-in if the chosen vendor does not anticipate these obligations.
Custom Software, Package, or Application: Three Different Logics
These three terms refer to distinct realities in business management. It’s better to start with concrete examples than abstract definitions.
Custom Software Addresses a Unique Need
Imagine a logistics company whose routes follow very specific rules (regulated time slots, refrigerated vehicles, customs constraints). No standard tool exactly covers this process. Custom-developed software replicates these business rules to the letter.
The downside: the initial development cost is high, maintenance relies on the team that designed it, and each evolution requires a new development cycle. Custom software is justified when the business process is your competitive advantage.
The Package Shares Management Features
A package (like an ERP) combines several modules: purchasing, sales, inventory, accounting, sometimes payroll. It is designed for a specific industry or a set of professions. SAP, Sage, or Odoo are well-known examples.
Its main advantage: data flows between modules without re-entry. Its limitation: configuration can be lengthy, and features you don’t need can clutter the tool. A package is suitable when multiple departments share the same data.
The Specialized Application Addresses a Specific Task
A CRM for sales tracking, an online invoicing tool, a project management application: each does one thing and does it well. These tools communicate with each other via APIs.
The risk: multiplying applications creates silos if the connectors are not reliable. But for a small structure, assembling two or three specialized applications costs much less than a complete package.
Concrete Selection Criteria for Your Company
Why do some companies regret their choice six months after deployment? Often because the decision was based on the visible features during the demonstration, not on the real constraints of daily use.
Here are the criteria that make a difference in practice:
- The actual functional coverage: list the tasks performed each week by each department. Compare this list to the proposed modules. A package that barely covers half of your processes will force you to keep parallel tools.
- The interconnection capability: check for the existence of documented and maintained APIs. An application without a reliable API becomes a technical dead end in a few months.
- The three-year pricing model: custom software is expensive upfront but low in subscription costs. A SaaS package involves a recurring cost that increases with the number of users. Calculate the total cost over three years, not just the entry price.
- Dependence on the vendor: if the vendor disappears or changes its pricing policy, can you export your data in a usable format? Ask this question explicitly before signing, and demand an export clause in the contract.
Transparency and Governance of Tools: An Often Overlooked Angle
The AI Act also introduces a transparency obligation towards users. If your management software uses AI to prioritize tasks, suggest business actions, or sort applications, your employees must be informed.
This requirement has a direct impact on the choice of solution. A vendor that does not clearly document the AI mechanisms integrated into its tool places you in a regulatory gray area.
Beyond compliance, the question of governance arises: who decides on the tools used in the company? In many organizations, each department chooses its own applications without coordination. The result: scattered data, duplicates, and an overall bill that is difficult to control.
Centralizing the software purchasing decision does not hinder agility: it prevents discovering afterward that three departments are paying for tools that do the same thing.
Quick Decision Grid Based on Your Situation
| Situation | Appropriate Solution | Trap to Avoid |
|---|---|---|
| Unique business process, competitive advantage | Custom software | Underestimating long-term maintenance costs |
| Multiple departments, shared data | Package (ERP) | Choosing an oversized ERP for the activity |
| Targeted need, limited budget | Specialized application | Multiplying apps without checking APIs |
| Tool integrating AI (HR, decision) | Any solution, with AI Act audit | Signing without a vendor compliance roadmap |
The choice between software, package, and application is not limited to a comparison of features. Regulatory compliance, internal governance, and the real cost over several years weigh as heavily as the usability of the interface. It is better to have a simple tool that covers your actual tasks than a complete solution that no one uses to its full capacity.
