Application Maintenance & Support: a technical partner for the long term
A piece of business software isn't something you build and forget. Needs evolve, usage patterns change, regulatory constraints shift, technology moves forward. Without ongoing support, even a well-built solution ends up accumulating technical debt, losing performance and creating risk.
Application Maintenance & Support (TMA) and ongoing support keep your application performant, aligned with your real needs and adaptable — without tying up scarce technical skills in-house.
What is application maintenance & support?
Application Maintenance & Support (in French, Tierce Maintenance Applicative, or TMA) covers the full range of maintenance and evolution services for a piece of software or application, delivered by an external provider — who may or may not be the original developer.
Corrective maintenance
Identifying and fixing bugs, faults and regressions that occur in production.
Evolutive maintenance
Evolving features in response to the organisation's new needs: new use cases, process changes, regulatory developments.
Preventive maintenance
Maintaining the technical health of the application: dependency upgrades, security, performance, reducing technical debt.
Why outsource application maintenance?
Maintaining high-level technical skills in-house is costly — and often hard to justify when development needs are irregular. Outsourcing application maintenance gives you access to focused expertise, available when you need it, without the constraints of a permanent hire.
This is particularly relevant for SMEs, mid-sized companies and local authorities that have one or more business-critical applications, but no in-house IT department sized to maintain them.
Who is this for?
Existing applications that need maintaining
Organisations that have had a bespoke application built — by us or by another provider — and need a technical partner to maintain and evolve it.
SMEs and mid-sized companies without an in-house IT department
That want to hand over the technical management of their tools to a trusted partner.
Local authorities
With one or more business applications in production, seeking rigorous, well-documented follow-up.
Organisations in transition
Taking over an application from a previous provider and needing to secure continuity of service.
Our approach
Takeover audit (if the application wasn't built by us)
Before taking on the maintenance of an existing application, we audit it: architecture, code quality, state of documentation, risk levels. This audit shapes our service commitments.
Tailored support agreement
We work with you to define the scope and service level suited to your situation: frequency of interventions, response times for issues, monthly evolution capacity, communication channels. Clear commitments, no catch-all clauses.
Follow-up and transparency
Every intervention is documented. You have access to the history of changes, fixes and technical decisions. Transparency is the foundation of a lasting partnership.
Anticipating changes
We don't just respond to requests. We track how your context is evolving — regulatory, technical, organisational — and flag upcoming work before it becomes urgent.
What this delivers
- An application that's maintained, secured and kept up to date on an ongoing basis.
- Reduced risk from technical debt and unaddressed vulnerabilities.
- The ability to absorb changes without heavy rebuilds.
- Internal teams freed from technical concerns.
- A partnership relationship: one point of contact who knows your tool in depth.
