Integration Beats Features: Why 60 Percent of DACH Buyers Walk Away Over Missing Connectivity

A demo calendar full of feature walkthroughs, a requirements sheet with fifty checkmarks ticked, and the deal still falls apart. That is not an edge case. According to a recent study from OMR Reviews and cse advisory, it is the norm in the DACH software market. Around 200 software buyers across Germany, Austria, and Switzerland were surveyed, and the finding is unambiguous: missing features rarely kill deals. What kills deals is whether a new solution actually fits into the existing system landscape. For anyone responsible for frontend or commerce decisions, that is not a footnote. It is the central gate standing between a good pitch and a live production system. Anyone who has sat through a buying process recognizes the pattern. The demo lands well, the team is convinced, and then IT asks the one question that decides everything: how exactly does this new system talk to what is already running?

The Second Gate in the DACH Buying Wave

This article continues our analysis of the 2026 DACH software buying wave, in which we already described the three core gates buyers pass through during vendor selection. If you want the full picture, the anchor piece covers all three gates in detail. Here, we go deeper on the second gate, because it is by far the most expensive one to miss. The study documents three figures, which we report here without added interpretation: 44 percent of respondents name integration into existing systems as the number one barrier in the selection process. 60 percent have already abandoned a purchase because of it. And 59 percent explicitly demand fast connectivity as a precondition for a buying decision.

These three numbers paint a consistent picture. Integration is not one criterion among many. It is the criterion that ultimately decides whether a deal closes or dies. Importantly, the study does not describe a niche concern. It surveyed buyers across industries and company sizes, and the results reflect a structural reality across the DACH region, where IT landscapes tend to be historically grown, heterogeneous, and rarely greenfield. Anyone selling into or buying within this environment has to plan for that reality, not against it.

Why Integration Risk Outweighs Feature Scope

A missing feature is a known, manageable risk. You can put it on a roadmap, bridge it with a workaround, or simply accept it. An integration risk behaves differently, because it usually becomes visible late in a project, often after the purchase decision has already been made and the implementation team has started work. That timing is what makes it so expensive. A feature gap costs discussion time. An integration gap costs months, budget, and in the worst case, the business side's trust in the entire project.

From a buyer's perspective, this is entirely rational. A new frontend system, a new page builder, or a new storefront solution is never operated in a vacuum. It has to pull product data from the PIM, reconcile prices and availability with the ERP, hand orders off to the shop backend, and in many cases also talk to systems like a CRM or a marketing automation platform. Each of these connections is a potential point of failure. The more feature scope a vendor promises, the more integration surface tends to be created, and the greater the risk that one of these connections does not work cleanly in practice.

As a result, buyer evaluation behavior is shifting away from feature lists and toward integration evidence. A solution with a narrower feature set but a demonstrably stable, documented connection into the existing system landscape frequently beats a functionally richer alternative with a vague integration story. This is not a matter of taste. It is a matter of operational risk, and operational risk is exactly what procurement teams and IT leaders across the DACH region weigh most heavily.

SAP, DATEV, and Microsoft 365, Translated to Commerce

The study names SAP, DATEV, and Microsoft 365 as the systems that new software most frequently, and most urgently, needs to integrate with. That is no surprise. These three systems form the operational backbone of finance, administration, and collaboration in many companies across German-speaking markets. For commerce and frontend leaders, that expectation translates directly, just with different system names and the same underlying logic.

In the commerce context, this means, first, the ERP. Pricing, stock levels, customer terms, and order status all live in the ERP, and any storefront has to reflect that data in real time or close to it. Second, the PIM. Product information, attributes, variants, and media are maintained in the PIM, and a new frontend must not duplicate or dilute that structure, but consume it cleanly. Third, the shop backend itself, whether that is an existing Shopware, commercetools, SAP Commerce Cloud, or another platform. Just as SAP, DATEV, and Microsoft 365 are expected to be connected to, not replaced, in the classic business software context, the same principle applies to the commerce backend. The goal is not to replace the existing system, but to attach a new frontend in a way that keeps data, processes, and governance in the backend intact.

This translation matters because it shows that the integration problem follows the same pattern across industries. Buyers do not want to have to migrate in order to innovate. They want to be able to connect, without putting what already works at risk.

What Fast Connectivity Actually Means in a Frontend Context

59 percent of surveyed buyers demand fast connectivity. But what does that actually mean when applied to a frontend project? At its core, it comes down to five factors that together decide whether a connection is fast or drags on for months.

First, existing connectors. A frontend solution that already ships production-proven connectors to common ERP, PIM, and shop-backend systems saves weeks compared to a solution where every connection has to be built as a bespoke integration project. Second, documented APIs. An API that is undocumented, or whose documentation is out of date, slows down every integration project, because engineering teams spend time reverse engineering instead of implementing. Third, data model mapping. How attributes, categories, and variants are mapped between systems determines whether integration is a clean, repeatable process or a chain of special cases.

Fourth, testability. An integration that cannot be realistically tested in a staging environment before going live is a risk that only shows up in production, usually at the worst possible moment. Fifth, and often underestimated, who operates the integration once it is live. A connection that works initially but needs to be re-adjusted with every ERP or PIM version upgrade generates ongoing costs that are rarely priced into the buying decision. That is exactly why the question of who operates the integration long term, not just who builds it initially, belongs in every vendor evaluation conversation.

Keep the Backend, Renew the Frontend

This is exactly where the core message behind Composable Commerce and a dedicated Frontend Management Platform comes in: keep the backend, renew the frontend. This is not a marketing line. It is a direct answer to the integration gate the study describes. If 60 percent of buyers abandon a purchase because integration into existing systems looks unclear or risky, the logical response is to minimize that risk by leaving exactly what already works untouched.

A composable approach deliberately separates frontend from backend. The ERP stays the ERP. The PIM stays the PIM. The shop backend remains fundamentally unchanged. What changes is the layer where customers interact with the brand: the storefront, the content experiences, the landing pages, the personalization. This separation drastically reduces the number of systems that need to be touched, migrated, or reconfigured as part of a project. Fewer systems touched means fewer integration surfaces, and fewer integration surfaces mean a smaller, more predictable risk.

For IT leaders, this is a decisive argument, because it directly addresses the concern that, according to the study, most frequently causes buyers to walk away. This is not about criticizing an existing system or selling a replacement. It is about demonstrating connectivity: a new frontend that fits into an existing SAP, ERP, PIM, or shop landscape without destabilizing it.

Logo Wall or Real Connection: How to Tell the Difference

Almost every vendor in the market shows a logo wall full of partner systems. The challenge for buyers is distinguishing whether a logo represents a real, production-proven connection or merely a theoretical compatibility that would still need to be built in a real project. This distinction can be tested during vendor selection with a handful of concrete questions.

First, is there a documented, publicly available technical description of the integration, or is the vendor simply marketing the partner system's name? Second, do reference implementations exist where this integration, or a very similar system combination, already runs in production, even if customer names cannot be shared for confidentiality reasons? Third, how are backend version changes handled, and who is responsible when an ERP or PIM version is upgraded? Fourth, can the integration actually be touched and tested in a proof of concept or sandbox setup before the purchase decision, or does it remain a promise on a slide until the contract is signed?

These questions reliably separate genuine connections from logo-wall compatibility. Vendors who can answer them openly, with concrete technical detail, signal that integration is a real product capability for them, not a marketing claim. Vendors who deflect or fall back on general statements should prompt buyers to apply extra caution, regardless of how convincing the feature demo was.

Conclusion: A Checklist for Vendor Selection

The study from OMR Reviews and cse advisory makes clear that integration is no longer a secondary criterion in the DACH software market. It is the criterion that decides whether a purchase closes or gets abandoned. For commerce and frontend decisions, that means structuring the vendor selection process accordingly, rather than checking integration only after the strategic decision has already been made. Concretely, it is worth working through a checklist: require documented APIs instead of general compatibility promises, ask about existing connectors to ERP, PIM, and shop-backend systems, walk through the data model mapping in detail, require sandbox testability of the integration before signing, and clarify who is responsible for operating the integration long term.

Anyone who works through these points before making a decision reduces the risk of landing in the 60 percent who had to abandon a purchase later on. And any vendor with clear answers to these questions is addressing the strongest purchase barrier currently known in the DACH software market. Composable Commerce, built on the principle of keeping the backend and renewing the frontend, is not an end in itself. It is a structural answer to a structural problem: the fear of what could go wrong when connecting to systems that are already in place.
