Implementation agreement
Deploying an existing system for a client is legally different from bespoke development. Scope depends on analysis, the schedule on the client's cooperation, and success on acceptance tests. We prepare an implementation agreement connecting these three elements, so the supplier knows what to deliver, the customer knows what to expect, and both parties know when the work is complete.

What we'll do for you
The most common implementation dispute is “that was outside the scope” versus “that is what we ordered”. A good agreement addresses this in advance, through analysis that establishes the scope and acceptance that closes it.

-
Analysis and solution design
We establish the initial phase contractually — its output is an approved design defining the implementation scope. This also covers a separate analysis agreement where phases are procured separately.
-
Scope and schedule
Milestones, stages and exactly what the fee includes — with rules for scope changes (change requests) and their effect on price and deadlines.
-
Client cooperation
Who supplies data, access and people, and by when — and what happens to deadlines and price if cooperation is delayed. This is the most frequent stumbling block in implementations.
-
Acceptance
Test scenarios, defect categories, deadlines for objections and deemed acceptance — making “complete” a legal status rather than a feeling.
-
Licences and the solution's future
Licence terms for the deployed solution, bespoke modifications, documentation and transition to maintenance (SLA).

How does an implementation agreement differ from a software development agreement?
The first question is whether implementation requires a separate agreement at all. If you commission bespoke software, deployment is usually a phase of the development agreement and no separate document is needed — what matters is that the development agreement actually covers acceptance and deployment, which we ensure when drafting it. A separate implementation agreement makes sense where no new work is created: an existing product is deployed, a supplier other than the software's author performs the implementation, or the phases are procured separately. Their substantive focus differs — development centres on specifications and rights to the result; implementation on scope established by analysis, client cooperation, integrations and acceptance. We cover mixed projects (deployment + bespoke modifications) in one combined agreement.
Why have a separate analysis and solution design phase?
Analysis turns expectations into an approved document — which becomes the measure of scope. Without it, disputes revolve around emails and presentations from the sales stage. Analysis may also be procured under a separate agreement before deciding on the entire implementation; we prepare both.
The client is not cooperating and the project has stalled. What can we do?
The agreement addresses precisely this scenario by defining the cooperation the client must provide, its timing and quality — and providing that delay extends deadlines and entitles the supplier to charge for waiting time or terminate the project. Even without an express clause, failure to provide necessary cooperation may trigger the statutory consequences of creditor delay, for example by affecting whether the supplier is in delay or the recovery of damages. This does not automatically create a right to charge for waiting time. The agreement specifies the deadlines, costs and termination conditions.
How should acceptance be structured so the project can be closed?
We recommend agreed test scenarios, defect categories (blocking versus other defects), a deadline for objections and deemed acceptance if that deadline passes without action or the system enters production use. For customers, we ensure deemed acceptance does not become a trap — the balance can be tailored to your needs.
How much does an implementation agreement cost?
It depends on the complexity of the project and schedules. We confirm the fee in advance after the initial consultation — and the agreed fee stands.
Legal Q&A
Common questions on this topic
-
Who owns the copyright in software created for me by a supplier?
An author's economic rights are non-transferable. A program commissioned directly from its author generally falls under the employee-work regime, and the customer exercises the rights unless the parties agree otherwise. Where a company supplies the software, however, the customer does not automatically obtain every entitlement: rights from its employees and subcontractors must be checked, and an appropriate licence or an assignment of the right to exercise economic rights must be agreed. The contract should also address source code, modifications and further licensing.

How long does a customer have to return goods bought online?
A consumer may withdraw from a distance contract with an online shop within 14 days without giving a reason. For goods, the period starts on receipt. Statutory exceptions include custom-made goods and unsealed goods protected for hygiene reasons. If the seller fails to provide proper withdrawal information, the period extends by up to 12 months.

When does the AI Act apply, and who does it cover?
The AI Act applies progressively: the first general provisions and prohibitions from 2 February 2025, rules for general-purpose AI models from 2 August 2025, with 2 August 2026 remaining the general application date. Regulation (EU) 2026/1744, however, postponed Chapter III, Sections 1 to 3, except Article 6(5): until 2 December 2027 for high-risk systems under Annex III and until 2 August 2028 for systems linked to regulated products under Annex I. It covers providers and businesses deploying AI; their specific duties depend on their role and the system.

Agile software development: a contract designed for sprints
Sprints do not fit a conventional contract for work: scope is flexible, software is delivered incrementally and acceptance is ongoing. A framework agreement with orders, budget caps, a definition of done and rules for the backlog and repository handover provides a solution.

Bespoke software: source code, SLAs and escrow determine your control
Paying for application development does not mean owning it. Without express terms, copyright law gives customers only narrow rights. The contract determines the rest: rights to the work, source code delivery, measurable SLAs and escrow if the supplier fails.
