The best-of-breed trap in professional services
Why best-of-breed is a delivery challenge for professional services
For agencies and system integrators, best-of-breed environments are now standard. One customer may need Shopify connected to NetSuite and HubSpot. Another may require Adobe Commerce, Microsoft Dynamics, and a separate PIM. A third may want a composable setup that combines search, marketplace, billing, and custom workflow tools.
At first, these look like individual integration projects. Over time, a pattern emerges. Similar system combinations get rebuilt across customers, mapping logic is duplicated, and every new endpoint adds another layer of complexity to an already fragile delivery model.
The issue is not that best-of-breed systems are the wrong choice for customers. It is that connecting them environment by environment through isolated integrations creates a delivery model that becomes harder to standardize and more expensive to support as project volume grows.
Why best-of-breed does not automatically mean best-connected
Choosing the strongest tool for each business function does not guarantee those tools will work well together. A customer may have an excellent commerce platform, a capable ERP, and a strong CRM, but if data between those systems does not move reliably, the value of the architecture starts to break down. Orders are delayed, stock visibility becomes inconsistent, and teams end up compensating for system gaps manually.
The most common response is to connect systems directly through custom integrations, native connectors, or webhooks. That can get a project live, but it rarely creates a scalable model. Each point-to-point connection introduces another dependency. Every API update, authentication change, or data model shift becomes a maintenance task. As more customer environments are added, the number of isolated connections grows and the delivery model becomes harder to monitor, govern, and support.
For ISVs, the pattern is closely related. Customers expect software to fit into a wider best-of-breed ecosystem. If integration requires heavy bespoke work every time, onboarding slows, product adoption weakens, and support complexity grows. Integration stops being a technical detail and becomes part of the product experience itself.
What this costs agencies, system integrators, and ISVs
The most visible cost is slower delivery. The deeper cost is operational drag.
When teams repeatedly build and maintain one-off integrations, project timelines stretch, support overhead rises, and margins become harder to protect. Delivery teams spend more time troubleshooting and less time building reusable value. Change requests become harder to absorb because integration logic is scattered across custom scripts, native connectors, and application-specific workarounds.
Instead of building a scalable integration capability, firms accumulate a growing portfolio of fragile implementations. That is the real best-of-breed trap: the systems are specialized, but the integration model behind them is not.
