The verdict in three sentences
An application maintenance contract (often called TMA in French-speaking markets) for an SME business application in Dublin costs 800 to 3,500 EUR excl. VAT per month in 2026, which is roughly 15 to 20 % of the initial development cost per year. The price matters less than the written commitments: response time, fix time, reversibility and the exact scope of the fee. An IT director who signs without an SLA grid and a technical inventory pays twice: once to the supplier, once in hours lost by the teams.
The three contract models and their 2026 prices
The Dublin market (local IT services firms, agencies, nearshore teams) offers three formulas. The right one depends on ticket volume and how critical the application is.
| Model | What is included | 2026 price (EUR excl. VAT) | Suitable if |
|---|---|---|---|
| Corrective-only fee | Bug fixes, security updates | 800 to 1,500 / month | Stable application, few changes |
| Corrective + preventive fee | Plus Node, React, PostgreSQL upgrades, monitoring | 1,500 to 2,500 / month | Used daily by 30 to 150 people |
| Full fee with enhancement credit | Plus 3 to 6 days of enhancements per month | 2,500 to 3,500 / month | Active roadmap |
| Time and materials | Days consumed on demand | Day rate 450 to 700 | Irregular needs |
| Annual percentage of build | Fee based on development cost | 15 to 20 % / year | Recent, well documented application |
| Per ticket | Payment per incident | 150 to 400 / ticket | Very low volume |
For an application that cost 120,000 EUR excl. VAT to build, the 15 to 20 % rule gives 18,000 to 24,000 EUR per year, so 1,500 to 2,000 EUR per month, consistent with the middle tier.
The SLA grid to demand
The SLA separates response time (the supplier acknowledges and starts analysis) from workaround or resolution time. Without that distinction, a « 4 h SLA » means nothing.
| Incident level | Example | Response | Workaround | Final fix |
|---|---|---|---|---|
| Blocking (P1) | Application down, invoicing stopped | 4 business hours | 8 business hours | 2 business days |
| Major (P2) | Key module failing, export impossible | 8 business hours | 2 business days | 5 business days |
| Minor (P3) | Display glitch, wrong filter | Next business day | Not required | Next release |
| Change request | New field, new report | 2 days for estimate | Not applicable | Per roadmap |
| Usual penalty | P1 or P2 breach | 5 to 10 % of monthly fee | Cap 15 to 30 % | Termination if repeated |
Out-of-hours on-call cover (evenings and weekends) usually adds 300 to 900 EUR per month. It is only justified if the application runs at night, for example for a warehouse or a public-facing platform.
What the contract must lock down
Beyond price, five clauses protect the IT director.
- Takeover phase: 10 to 20 billed days (4,500 to 12,000 EUR) to audit the code, document the architecture and install monitoring. It avoids month-three surprises.
- Scope inventory: list of Git repositories, environments, libraries and dependencies covered. Anything missing will be billed as time and materials.
- Reversibility: delivery of documentation, access and a 3 to 5 day handover at the end of the contract.
- Monthly reporting: ticket count, actual times, identified technical debt, versions due for upgrade.
- Code ownership: the code remains the client's property, hosted on its own GitHub or GitLab account.
A 12-month contract with automatic renewal and 3 months' notice is standard. Avoid 36-month commitments without an exit clause tied to SLA performance.

Mini case study
Aoife, IT director of a fictional 220-employee SME near Dublin, runs a planning application built in-house for 95,000 EUR. Her lead developer is leaving. Option 1: hire an experienced developer at 70,000 EUR gross, about 78,000 EUR with employer costs per year. Option 2: a maintenance contract at 2,100 EUR per month with 3 enhancement days included, plus a 12-day takeover at 600 EUR, so 32,400 EUR in the first year. Even adding 10 extra days for unplanned changes (6,000 EUR), Aoife saves close to 39,600 EUR and gains SLA-backed continuity that a single employee cannot provide during holidays.
FAQ
What is the average price of an application maintenance contract for an SME in 2026?
Most contracts fall between 1,500 and 2,500 EUR per month for a business application used daily. The low end (800 EUR) only covers corrective maintenance.
How do I calculate an annual maintenance budget?
Take 15 to 20 % of the initial development cost. An application that cost 120,000 EUR therefore needs 18,000 to 24,000 EUR per year.
Is a 4 h SLA realistic?
Yes for responding to a blocking incident during business hours. The final fix usually takes 1 to 2 days, which is why you should demand a workaround within 8 h.
Should we pay for a takeover phase?
Yes, usually 10 to 20 days. Without an initial audit, the supplier discovers the code during incidents, which slows every fix.
What day rate for enhancements in Dublin?
Plan on 450 to 550 EUR for an experienced developer and 600 to 700 EUR for a senior or architect profile. Day credits included in the fee are often 10 to 15 % cheaper.
