What really breaks cooperation between a client and a software house 

Problems in cooperation do not start with code

When cooperation between a client and a software house begins to deteriorate, technology is very rarely the first symptom. Much more often, communication tensions appear, decision-making is delayed, frustration builds up on both sides and there is a feeling that “the project is slipping out of control”. From the outside, it looks like an organizational or competence-related problem. In reality, it is almost always the result of incorrect assumptions adopted at the very beginning of the cooperation.

E-commerce is an area in which a software house does not deliver just code. It delivers a solution that is meant to operate within a real, complex business. If both sides do not share a common understanding of their roles, responsibilities and the project’s objective, even the best technology is not able to save the relationship.

Unspoken expectations as a source of conflict

One of the biggest enemies of good cooperation are expectations that were never clearly articulated. The client assumes that the software house will “understand the business”, while the software house assumes that the client “knows what they want”. In practice, both sides operate on assumptions, and the project develops based on incomplete information.

Over time, disappointment appears. The client does not see the results they expected. The software house feels that it is implementing constantly changing requirements. Each subsequent iteration deepens frustration, and instead of conversations about solutions, emotions and mutual accusations emerge.

Mature cooperation begins with difficult conversations about expectations, constraints and priorities. Their absence sooner or later returns at the most costly moment of the project.

Treating the software house as a contractor, not a partner

One of the classic mistakes on the client side is reducing the software house solely to an execution role. The company “orders”, the software house “delivers”. Such a model may work for simple projects, but in e-commerce it breaks down very quickly.

In complex projects involving migrations, integrations and process redesign, the software house must be able to ask uncomfortable questions, challenge assumptions and propose alternatives. If the client expects only the execution of a requirements list, without space for dialogue, the project loses one of its most important elements – an external, critical perspective.

On the other hand, a software house that blindly executes every instruction also harms the project. Partnership requires responsibility on both sides.

Lack of decision-making authority on the client side

One of the most destructive factors for cooperation is the lack of real decision-making authority on the client side. When decisions are dispersed, approved by many people or postponed over time, the project begins to stall.

The software house needs clear signals: what is a priority, what can wait, which compromises are acceptable. Without this, the technical team operates blindly, and every decision becomes a potential source of conflict. Delays accumulate, the budget shrinks, and the atmosphere of cooperation deteriorates week by week.

Well-functioning projects always have a clearly defined owner on the client side – a person who understands the business and has the mandate to make decisions.

Changing direction during the project without awareness of the consequences

Changes in e-commerce projects are natural. The problem begins when they are introduced without understanding their impact on the entire project. The client perceives a change as a “minor clarification”, while the software house sees a rebuild of logic, testing and integrations.

If these differences in perception are not communicated openly, a sense of injustice appears very quickly. The client feels that “everything requires extra payment”. The software house feels that the project is being destabilized without respect for prior agreements.

Mature cooperation is based on transparent change management. Every decision has its cost – financial, time-related or quality-related. A lack of this awareness is one of the main reasons for conflict escalation.

Communication limited to statuses and tickets

In many projects, communication is reduced to statuses, tickets and task lists. Formally, everything is correct, but there is no conversation about the broader context. The software house executes tasks, the client accepts subsequent stages, and no one looks at the project as a whole.

In e-commerce, such an approach quickly leads to misaligned expectations. The platform may be technically correct, but it does not meet real business needs. The client feels that “this is not it”, while the software house feels that “we did exactly what was agreed”.

Regular, substantive communication about goals, risks and project direction is just as important as the correct execution of the backlog.

The wrong moment for a project

Sometimes cooperation deteriorates not because either side makes mistakes, but because the project was started at the wrong time. Organizational changes, financial pressure, lack of resources on the client side – all of this affects the quality of cooperation.

The software house may deliver according to plan, but the client has no space to truly lead the project. Decisions are postponed, feedback is delayed, and tension builds up. In such situations, it is very easy to fall into mutual accusations, even though the problem lies deeper – in the organization’s readiness to execute the project.

Technology as a convenient scapegoat

When cooperation begins to break down, technology very often becomes a convenient scapegoat. “The platform can’t handle it”, “the system is too complex”, “it’s the architecture’s fault”. Meanwhile, the source of the problems lies in decisions, communication and the way the project is managed.

Platforms such as Shopware offer enormous flexibility and development possibilities, but they require a partnership-based approach to implementation. Technology will not replace trust, responsibility and a shared objective.

Good cooperation is a process, not a contract

The best e-commerce projects are not based on a perfect contract or a detailed specification. They are based on a relationship in which both sides understand their role and take responsibility for the final outcome. The software house is not just a supplier, and the client is not just a commissioning party.

At CREHLER, we place great emphasis on how cooperation looks, not only on what is delivered. Working on Shopware implementations, we know that project success begins with trust, transparency and a shared understanding of the goal. If you feel that cooperation with a technology partner resembles a struggle more than a joint project – a conversation with a team that can organize the process even before development starts is often the best first step.
