Essential
For moderate-traffic apps where continuity matters but isn't mission-critical.
What's included
- Bug and incident fixes
- Security updates
- Uptime monitoring
- Email support
SLA: response within 24h — fix within 5 business days
Your application shipped. Not left behind.
Going live isn't the finish line — it's the start. We keep what we built together stable, secure, and evolving, with clear commitments and service levels that match your stakes.
Why TMA
Without maintenance, applications quietly degrade.
- Dependencies age. Security issues appear. OS and browser updates break behaviours that worked yesterday.
- Users report bugs. Without a maintenance agreement, every incident becomes a negotiation: who owns it, how fast, at what cost.
- Your business evolves. Small functional improvements pile up — without TMA, they wait for a big release or a new project.
- Your technical team changes. Product knowledge walks out with people. Rehzzo stays.
What we cover
Two maintenance types. One counterparty.
Corrective maintenance
What can't wait — incidents, bugs, vulnerabilities.
- Fixing functional and technical bugs
- Security updates and dependency patches
- Production incident handling
- Compatibility with new OS, browser, and third-party API versions
- Proactive monitoring — we often spot issues before you do
Evolutive maintenance
What keeps the product alive — small changes that don't warrant a project.
- Minor functional improvements within the allocated day envelope
- Performance tuning
- Adjustments from user feedback
- Small integrations and UI tweaks
- Ongoing technical guidance on what's next
Service levels
Three tiers. Clear commitments at each step.
Each tier matches your application's criticality and how fast you need us. SLAs are contractual.
Business
For actively used production apps with regular users and real business continuity needs.
What's included
- Everything in Essential
- Minor functional improvements (monthly day allowance)
- Application monitoring and alerting
- Email and phone support
- Monthly review and evolution roadmap
SLA: response within 8h — fix within 48h
Critical
For apps where downtime directly hits revenue or operations.
What's included
- Everything in Business
- On-call coverage outside business hours
- Real-time monitoring with immediate alerting
- Larger evolution envelope
- Dedicated technical contact
- Weekly review
SLA: response within 2h — fix within 24h — 99.9% availability commitment
SLAs are defined in the contract with penalty clauses if we miss them. We commit to what we can sustain — not to what sounds reassuring at signing.
Handover
A smooth transition from delivery.
Handover audit
At the end of every Rehzzo project we formalise an application audit — code health, dependencies, watch points, documentation. That baseline feeds the TMA agreement. No surprises six months after launch.
Monitoring setup
We configure tooling for your tier — availability, performance, application errors. You get alerts. We get alerts. Often before you notice.
Contract activation
We define scope, SLAs, evolution allowance, and termination terms. Everything is written down — including our commitments and penalties if we fall short.
Ongoing relationship
A dedicated channel, regular reporting per tier, and a planned evolution roadmap. Not something you sign and forget.
Our commitment
We maintain what we built. Not what we're discovering.
We know the code
We wrote it. No time lost reverse-engineering an unfamiliar codebase, no regression risk from missing context.
SLAs are contractual — with teeth
If we miss our responsiveness commitments, the contract defines consequences. This isn't sales patter.
Evolution is planned
We don't only react to incidents. We anticipate, propose, and schedule. Your product moves forward even without a new major project.
Exit is designed in
If you bring maintenance in-house or switch providers, we plan knowledge transfer. No information hoarding — it's not in our long-term interest.
