Building the foundations we kept rebuilding
Every product has its own purpose, users and workflows. But behind the interface, many products depend on the same foundations: authentication, AI agent setup, messaging, email, payments, integrations, and the infrastructure that connects these capabilities to the rest of the application.
As ZeroComplex built and expanded its own products, these needs kept appearing. Each new product required a version of capabilities the team had already built or had to build again. Over time, the work beneath the product began to demand attention that should have been going into the problems each product was created to solve.
Backoffice grew out of that experience: a shared infrastructure layer intended to make common capabilities reusable across ZeroComplex products and, where appropriate, available to other teams building software.
The Challenge
Each new product brought familiar work with it
Building a product is not only about the features a customer sees. It also means connecting the systems that make those features function: configuring AI agents, managing communication channels, integrating payment providers, handling credentials, and creating reliable ways for application components to work together.
When those foundations are built separately for each product, engineering effort gets repeated. Implementations can diverge, maintenance becomes harder to coordinate, and a change to a shared capability may need to be made in several places. The cost is not always obvious in a feature list, but it shows up in development time, duplicated decisions and the ongoing work required to keep systems consistent.
For ZeroComplex, this was a problem experienced firsthand while building and operating products with different requirements. The goal was not to make every product identical. Each product still needed room for its own workflows and user experience. The opportunity was to stop treating common infrastructure as a fresh project every time.
Why ZeroComplex
Build the shared layer once, then let products build on it
Because ZeroComplex encountered this challenge across its own products, Backoffice began as an internal response to a recurring engineering problem. The team needed a more systematic way to provide common capabilities without tightly coupling every product to one implementation or forcing product-specific needs into a generic template.
The approach was to separate reusable infrastructure from the applications that depend on it. Shared capabilities could be developed and maintained in one place, while individual products retained control over their own interfaces, business logic and customer experience.
This also created the possibility of using the same infrastructure beyond ZeroComplex's internal portfolio. If the underlying capabilities could be packaged cleanly, other businesses could use them without each having to assemble every component from scratch.
Solution
A reusable foundation for building and operating products.
Backoffice is being developed as a shared layer for capabilities that recur across applications. Rather than presenting a single end-user product, it focuses on the infrastructure and integrations that help other products work.
AI agent infrastructure. Common agentic capabilities can be made available as reusable building blocks, reducing the need to recreate agent setup and supporting infrastructure for each product.
Communication services. Messaging and email capabilities can be connected through a shared layer, allowing products to use communication workflows without treating every channel integration as a separate implementation.
Payment infrastructure. Payment-provider integrations and related workflows can be organised as shared capabilities, while each product retains responsibility for its own commercial logic and customer experience.
External integrations and tools. A common approach to connecting external APIs and services helps reduce duplicated integration work and makes it easier to maintain connections as products evolve.
A modular approach. The goal is to keep these capabilities reusable without making every product behave the same way. Products can adopt the components they need and compose them around their own requirements.
The principle is straightforward: common infrastructure should be dependable and reusable, while the product-specific work should remain focused on the customer and problem being served.
Result
Less repeated groundwork. More attention on the product itself
Backoffice gives ZeroComplex a path towards reducing duplicated implementation across its product portfolio. By developing recurring capabilities as a shared layer, the team can aim to spend less time rebuilding common foundations and more time on the workflows, experiences and domain-specific problems that distinguish each product.
A shared approach can also make maintenance more consistent: improvements to a common capability can be considered centrally rather than independently recreated in multiple applications. The value will depend on how well the components are separated, documented, secured and adopted by each product.
Backoffice is an evolving infrastructure initiative, so its impact should be measured through real implementation data, for example, time to integrate a capability, duplicated code or maintenance effort avoided, and the number of products successfully using each shared component. We will add quantified outcomes when those measurements are available.
Conclusion
A more consistent foundation for building products
The purpose of shared infrastructure is not to make product development abstract or remove the differences between products. It is to handle recurring technical work more systematically so teams can focus on what makes each product useful.
Backoffice reflects a lesson from building software across different domains: some foundations are worth building once and improving over time. By turning recurring capabilities into a shared layer, ZeroComplex is working towards a more consistent way to build, connect and operate its products.
“We kept rebuilding the same foundations across different products. Bringing capabilities like AI agents, communications, and payments into a shared infrastructure layer means we can focus our best energy on the problems each product was created to solve.”
