Service-Level Agreements and Support
Severity levels, response objectives, escalation and exit terms, written down before support begins.
An SLA should tell you exactly what happens when something breaks: who responds, how fast, who takes over if it is not progressing, and how you check that promises were kept. Timeline Digital writes service-level agreements in plain language, with exact figures agreed per contract based on how critical the system is, rather than copied from a generic template.
What your SLA puts in writing
- Severity levels defined with examples from your own operations
- Response and resolution objectives for every severity level
- A written escalation path with named contacts
- Reporting you can check against the contract yourself
- Exit and handover terms stated plainly from day one
What does a service-level agreement define?
An SLA is useful only if it removes ambiguity. Ours are short documents in plain language that answer six questions before support ever begins.
Severity classification
Every incident and request is classified by business impact, from a full outage at the top to cosmetic issues at the bottom. The levels are defined with examples from your own operations, so classification is a lookup, not a negotiation.
Response and resolution objectives
Each severity level carries a written response objective (how quickly an engineer acknowledges and starts work) and a resolution objective (how quickly normal operation or a safe workaround is restored). The figures are agreed per contract.
Escalation path
A written ladder that says who takes over when an issue is not progressing, and the triggers that move it upward. Escalation is a right you hold under the agreement, not a favor you have to request.
Reporting cadence
How often you receive a written account of incidents, performance against the agreed objectives and completed work, in a format you can check against the contract yourself.
Review cadence
Scheduled points where the agreement itself is reviewed. Severity definitions, objectives and support tiers are adjusted as the system and your business change, instead of drifting out of date.
Exit and handover terms
Notice periods, handover obligations and knowledge transfer, stated plainly at the start of the relationship while both sides are on good terms, not negotiated at the end when they may not be.
Most agreements use four severity levels. The names, examples and figures are tailored to each client, but the structure looks like this:
| Severity level | What it means | Typical example | How it is handled |
|---|---|---|---|
| Severity 1, Critical | The system is down, or a core business function is unusable with no workaround | Orders cannot be processed; staff cannot log in; data loss in progress | The fastest response window in your contract. Work continues until service is restored, with updates at agreed intervals |
| Severity 2, High | A major function is degraded; a workaround exists but is costly or slow | A key report fails; one location cannot use the system; performance badly degraded | Priority handling ahead of routine work, with a committed response window |
| Severity 3, Medium | A limited fault with a reasonable workaround; normal operation continues | A non-core screen errors; an export needs manual correction | Scheduled into the normal support queue against a stated objective |
| Severity 4, Low | Cosmetic issues, questions and minor requests | A label reads wrong; a layout issue in one browser | Batched sensibly and handled through routine releases and service reviews |
The response and resolution figures attached to each level are the heart of the agreement, and they are set per contract. A number printed on this page would be either padded or optimistic. A number in your contract is enforceable.
Which support tier fits your system?
Not every system needs the same cover, and paying for cover you do not need is waste. We shape tiers around one question: what does an hour of downtime actually cost this business?
Business-hours cover
For internal systems where an issue found overnight can reasonably wait for the working day: back-office tools, reporting platforms, systems with a manual fallback. Support runs through an agreed business-day window, with response objectives sized to match.
Extended cover
For systems where evenings and weekends matter: customer-facing portals, booking and ordering systems, operations that run beyond office hours. High-severity incidents are covered through a wider window agreed in the contract.
Critical-system cover
For systems where downtime stops the business outright. The widest coverage window for Severity 1 incidents, on-call arrangements, the strictest response objectives in the agreement and the closest monitoring.
You will notice there are no hours, uptime percentages or response minutes printed on this page. That is deliberate. Published one-size-fits-all numbers are either padded so the vendor is always safe, or optimistic in ways that fail exactly when it matters. The coverage window, response objectives and any availability commitments are agreed per contract, based on how critical the system is, what your operations need and what your budget supports. They are then written down and reported against.
How does escalation work?
Escalation is what stands between you and an issue that quietly drifts. The path is written into the agreement, with the triggers that move an issue upward and the people who take it.
First-line engineer
Every request is acknowledged through the agreed channel, classified by severity and picked up by an engineer who begins diagnosis and keeps you updated at the agreed interval.
Senior engineer
If the issue is harder than it first appeared, or is not progressing within its objective, a senior engineer with deeper knowledge of the system takes over. This trigger is time-based and automatic, not something you must push for.
Engagement manager
A named manager owns communication when an incident is serious or prolonged: coordinating engineers, making scope decisions and giving you one accountable person to talk to.
Leadership review
If a commitment has been missed or an incident was severe, it reaches company leadership and triggers a post-incident review: what happened, why, and what changes so it does not repeat.
You can also escalate from your side. If you believe an issue is misclassified or progressing too slowly, the agreement gives you a direct route to the next level, with named contacts rather than a generic inbox. The day-to-day support flow that sits underneath this path is described on our software maintenance and support page .
How are maintenance windows and planned changes handled?
Planned work should never surprise you. The agreement defines when changes happen, how you hear about them, and what protects you if a change misbehaves.
Agreed windows
Planned maintenance runs inside windows chosen with you, in the hours when the system matters least to your operations. The windows are written into the agreement, not decided release by release.
Advance notice
Scheduled changes are announced ahead of time through the agreed channel, with what is changing, why, the expected impact and how long the work should take.
Tested and reversible
Changes are applied to a staging environment and tested against the system’s critical paths first. A backup and a rollback plan exist before any risky change reaches production.
Emergency changes
A serious security vulnerability cannot wait for the next window. Emergency changes move faster, but they are still communicated as they happen and documented afterward, with the same rollback discipline.
What happens if the relationship ends?
An SLA should be easy to leave. That sounds strange coming from a vendor, but lock-in produces resentful clients and lazy service. Every agreement states its exit terms plainly from day one.
Documentation stays current
Architecture notes, environment setup, deployment steps and a credentials inventory are maintained during the engagement, not written in a rush at the end. Handover starts from documents that already exist.
Knowledge transfer
During the notice period we run structured sessions with your incoming team or vendor: how the system is built, where the sharp edges are, and how day-to-day operations actually run.
You hold the keys throughout
Code repositories, data and infrastructure accounts are owned by you for the whole engagement, so exit involves no transfer of ownership, only of responsibility.
Plain notice terms
Notice periods are stated in plain language, and support continues at full quality through the notice window. There is no degradation of service to punish a departing client.
Ownership is the foundation that makes clean exits possible. How Timeline Digital handles code, data and account ownership throughout an engagement is documented on the intellectual property ownership page.
What do we expect from the client side?
A service-level agreement binds both parties. Our commitments assume a few things from your side, and they are written into the same document so neither side is guessing.
A named contact
Someone with the authority to confirm priorities, accept changes and make the call when two urgent things compete. Deputies can be named for holidays and absences.
Access that works
Working credentials and access to the environments we support. Response objectives assume we can reach the system; time spent waiting for access is time the incident stays open.
Honest severity classification
Classifying by real business impact. When everything is marked critical, nothing is, and the genuinely critical incident loses the protection the SLA was built to give it.
Timely decisions
Acceptance of completed work and decisions on proposed changes within agreed windows, so fixes and improvements reach production instead of queuing behind an approval.
Telling us what changes
Advance notice of things that affect the system: infrastructure changes on your side, third-party contract changes, or a marketing push that will multiply traffic overnight.
What shapes the terms and cost of an SLA?
There is no honest price list for support commitments before someone has looked at the system. What we can tell you in advance is which factors move the terms and the number.
Timeline factors
How quickly cover can begin depends on whether we built the system or are taking it over, how complete the documentation is, how fast access and credentials are transferred, and whether monitoring is already in place.
Cost factors
The price of an SLA moves with how critical the system is, the coverage hours you need, how strict the response objectives are, the size and age of the codebase, and any compliance obligations. Stronger commitments cost more than relaxed ones, and that trade-off is presented openly.
Client involvement
Terms assume a named contact who can classify priorities and accept changes. Where that person is highly available, tighter objectives are realistic; where they are not, the agreement is shaped to match.
Risks we manage
Undocumented behavior, aging dependencies and single points of failure make commitments risky. If part of a system is too fragile to guarantee on day one, we say so, and the SLA includes the work to bring it under full cover.

Across 1,500+ delivered projects and 860+ active clients in 25+ countries, long-running support relationships are the norm rather than the exception, including work connected to a public-sector program in Qatar. The agreements described on this page are the working documents behind those relationships, not marketing.
Service-Level Agreement Questions
Response times, critical incidents, reporting, changing terms and ending the contract, answered directly.
Response objectives are agreed per contract, by severity level and by how critical the system is, so we do not publish a single guaranteed number here. A figure printed on a marketing page would either be padded to stay safe for every case or too optimistic to be honest for the hardest ones. What you can rely on is the structure: every agreement states a written response and resolution objective for each severity level, an escalation path if an issue is not progressing, and reporting that shows how actual performance compared with those objectives.
A critical incident is one where the system is down or a core business function is unusable with no reasonable workaround: orders cannot be processed, staff cannot log in, data is being lost, or a security breach is in progress. The precise definition is written into your SLA using examples from your own operations, because a fault that is cosmetic for one business can be existential for another. Agreeing the definition in advance means nobody argues about classification while something is on fire.
Yes. Every agreement includes a review cadence, and terms can be adjusted at those points: moving to a wider coverage window, tightening response objectives for a system that has become critical, or relaxing cover for one that matters less than it used to. Changes are agreed in writing and priced openly. This is normal and expected. The SLA that suited a pilot rarely suits the same system three years later, when a whole department depends on it.
The reporting cadence is agreed in your contract. Reports typically cover incidents in the period, how response and resolution performance compared with the agreed objectives, work completed, upcoming planned maintenance, and recommendations such as aging dependencies that need attention. The point of reporting is that you can check our performance against the contract yourself, rather than taking our word for it. Format and frequency are matched to your side: some clients want a short written summary, others want a standing review call.
The agreement states its notice period plainly, and support continues at full quality through that period. During the notice window we run a structured handover: current documentation, architecture and deployment notes, a credentials inventory, and knowledge transfer sessions with your new team or vendor. Because you own the code, data and accounts throughout the engagement, there is nothing to ransom back. We would rather clients stay because the service is good than because leaving is painful.
Development projects include a stabilization period after go-live, agreed in the project contract, during which defects in the delivered scope are fixed as part of the project. Longer-term support is a separate service-level agreement, sized to how critical the finished system is. Most clients move from the stabilization period straight into an SLA so there is no gap in cover, but it is a choice, not an obligation: the code, documentation and infrastructure are yours either way.
