CSMS Choices Explained: Building vs. Buying Your Next CSMS

One of the most frequent dilemmas we encounter in the realm of software solutions is the age-old debate: to build or to buy? This question, seemingly simple on the surface, is layered with complexities and considerations.
CSMS Choices Explained: Building vs. Buying Your Next CSMS

On one hand, building a custom solution promises a tool tailored to your exact needs, offering a unique fit for your organization's challenges. On the other, purchasing an off-the-shelf product provides immediate implementation, backed by the assurance of a solution that's been tried and tested by others.

The decision is not just about choosing between customization and convenience. It's about weighing the long-term benefits against the short-term gains, understanding the nuances of your organization's requirements, and determining the best strategic fit.

The journey to answering this question is intricate, requiring a deep dive into the specifics of your business needs and the broader landscape of software solutions.

The Case for Building a Custom CSMS

Customization and Flexibility

A custom-built CSMS (or CPO Platform) offers a solution tailored to the specific needs of the business. It provides unparalleled flexibility, ensuring that the system can adapt to evolving requirements and unique challenges. 

Unlike off-the-shelf solutions, which often come with a one-size-fits-all approach, a custom-built system is designed from the ground up to cater to the unique demands of the organization. This means that as the business grows or pivots, the CSMS can be adjusted accordingly, ensuring that it remains relevant and effective in meeting the company's objectives.

Direct Database Access

With a custom-built system, businesses have direct access to their database. This can be crucial for integrations, data extraction, and overall system transparency, allowing for more in-depth insights and analytics. 

Direct database access eliminates the need for intermediaries or third-party tools, which can sometimes limit the depth and breadth of data analysis. This direct connection empowers businesses to make data-driven decisions, harnessing the full potential of their information to drive growth and innovation.

Ownership, Control, and Independence

Owning the intellectual property of a custom-built CSMS can be a strategic advantage. It ensures that the business isn't dependent on third-party vendors and can adapt its operations independently. 

This level of control means that businesses can make changes, updates, or modifications to the system without waiting for vendor approval or facing additional costs. 

Moreover, owning the intellectual property safeguards the company from potential disruptions, such as vendor discontinuation or changes in licensing agreements, ensuring uninterrupted operations.

Long-Term Vision Alignment

Building a custom solution ensures that the CSMS aligns with the long-term vision and strategy of the company, rather than adapting to a pre-existing system's limitations. 

This alignment ensures that the software becomes an integral part of the company's growth trajectory, evolving in tandem with its goals and objectives. Instead of retrofitting an off-the-shelf solution to fit the company's vision, a custom-built CSMS is inherently designed to support and amplify the company's strategic direction, making it a powerful tool for long-term success.

Competitive Differentiation

A unique CSMS can serve as a differentiator in the market, offering features or efficiencies that competitors might not have. In an increasingly competitive landscape, having a distinct edge can be invaluable. 

A custom-built CSMS allows businesses to introduce innovative features, streamline operations, or offer unique user experiences that can set them apart from the competition. This differentiation not only attracts customers but also positions the company as a leader and innovator in its field, paving the way for sustained competitive advantage.

The Case for Buying an Off-the-Shelf CSMS

Speedy Time to Market

In the fast-paced world of electric vehicle charging, time is of the essence. For CPOs looking to establish a foothold or expand their presence, delays can mean missed opportunities. Purchasing a ready-made CSMS solution offers a significant advantage in this regard. 

Instead of spending months, or even years, developing a system from scratch, CPOs can implement an off-the-shelf solution in a fraction of the time. This rapid deployment allows them to quickly respond to market demands, seize new opportunities, and stay ahead of competitors.

Cost Considerations

At first glance, off-the-shelf CSMS solutions might seem like the more economical choice. The upfront costs are typically lower than developing a custom system. However, it's crucial for CPOs to take a holistic view of expenses. 

Over time, subscription fees, costs associated with change requests, and charges for additional features can add up. While the initial outlay for a SaaS solution might be less daunting, the long-term financial commitment should be thoroughly evaluated to ensure it aligns with the company's budgetary constraints and financial goals.

Reduced Initial Risk

Venturing into the unknown can be daunting. When building a custom CSMS, there's always a risk that the final product might not fully meet the company's needs or that unforeseen challenges might arise during development. 

With a ready-made solution, this risk is significantly mitigated. Companies have the opportunity to demo the product, test its features, and assess its compatibility with their operations. This "try before you buy" approach provides a safety net, ensuring that CPOs invest in a system that aligns with their immediate requirements.

Continuous Updates

The tech landscape is ever-evolving, with new advancements and security threats emerging regularly. For a CSMS to remain effective and secure, it needs to keep pace with these changes. 

Many SaaS providers recognize this need and offer regular updates to their products. These updates ensure that the system benefits from the latest technological advancements, remains compatible with new hardware or software integrations, and is fortified against the most recent security threats. For CPOs, this means less worry about obsolescence and a reassurance that their system is always at the cutting edge.

Additional Factors for CPOs to Consider

Integration with Existing Systems

Seamless integration is the backbone of efficient operations. When considering a new CSMS, it's paramount to assess how well it can mesh with the existing infrastructure. A system that doesn't integrate smoothly can lead to operational hiccups, data silos, and increased manual work, negating any potential benefits. 

On the other hand, a CSMS that can effortlessly blend with current systems can enhance workflow, improve data flow, and boost overall efficiency. Therefore, before making a decision, CPOs should conduct a thorough compatibility check to ensure minimal disruptions and maximum synergy.

Vendor Stability and Direction

The longevity and future prospects of a SaaS vendor play a crucial role in the decision-making process. A vendor's track record, financial health, and market reputation can offer insights into their stability. Furthermore, understanding a vendor's strategic direction can help gauge if their future updates and innovations will align with your business's evolving needs. 

Any abrupt changes in a vendor's quality, shifts in their business focus, or, worst-case scenario, discontinuation of services can have detrimental effects on a CPO's operations. Hence, it's essential to partner with a vendor that showcases consistency, reliability, and a vision that resonates with your business goals.

Potential Vendor Lock-in

The digital landscape is ever-evolving, and businesses must retain the flexibility to adapt. However, some SaaS solutions come with strings attached, making it cumbersome to migrate to a different platform if the need arises. Whether it's due to proprietary data formats, steep migration costs, or complex contractual bindings, being "locked-in" can stifle a business's agility. 

Before committing to a solution, CPOs should evaluate the ease of data portability and understand any potential barriers to switching platforms, ensuring they retain the freedom to pivot as market dynamics change.

Business Size, Needs, and Future Plans

Every business is unique, and so are its requirements. A startup CPO, still carving its niche, might prioritize rapid deployment and cost-effectiveness. In contrast, an established player might focus on customization, scalability, and advanced features. 

Recognizing where the business currently stands and where it aims to be in the future is pivotal. By aligning the CSMS choice with the company's present needs and future aspirations, CPOs can ensure they invest in a solution that grows and evolves with them, rather than becoming a limiting factor.


As businesses expand, their operational needs become more intricate. The CSMS chosen should not only cater to the present demands but also be equipped to handle future growth. While many off-the-shelf solutions boast scalability, they might have limitations when it comes to customization during expansion phases. 

On the other hand, a custom-built system offers granular control, allowing businesses to tweak and scale aspects as per their specific growth trajectory. CPOs should, therefore, assess the scalability potential of a CSMS, ensuring it can accommodate both immediate requirements and future expansion plans.

Cost and Timeliness of Customizations

When opting for an off-the-shelf CSMS solution, it's essential to recognize that while these products cater to a broad audience, they might not address every unique need of your business. Over time, as your operations evolve or market demands shift, you might find the need for specific features or customizations. 

While many SaaS vendors do offer customization services, these often come at a premium. Moreover, because these vendors cater to a wide customer base, your customization request might be placed in a queue, competing for attention with the needs of numerous other clients. This can lead to significant delays, and there's no guarantee that your request will be prioritized, regardless of its importance to your operations. Such delays can impact your business's agility and responsiveness to market changes. 

Furthermore, the costs associated with these customizations, both in terms of finances and time, can add up, potentially offsetting the initial savings of choosing an off-the-shelf solution. It's crucial for CPOs to evaluate the flexibility of potential SaaS solutions and gauge the vendor's responsiveness to customization requests before making a commitment.


The decision to build or buy a software solution is pivotal and should involve a collaborative effort from multiple stakeholders within an organization. Typically, this decision should be spearheaded by the Chief Information Officer (CIO) or Chief Technology Officer (CTO), given their expertise in technological infrastructure and strategy. However, it's equally crucial to involve department heads and end-users, as they can provide insights into specific requirements and practical challenges. 

Additionally, the Chief Financial Officer (CFO) should weigh in on budgetary considerations, while the CEO or executive leadership should assess the decision's alignment with the company's broader strategic goals. By ensuring a cross-functional approach, organizations can arrive at a well-informed and holistic decision that serves both immediate needs and long-term objectives.

In the final analysis, the essence of a business lies in its unique offerings and competitive edge. While off-the-shelf software solutions may provide broad functionalities, they often fall short of capturing the distinct nuances and requirements of individual businesses. It's a rare occurrence to find a one-size-fits-all solution that aligns perfectly with every facet of your operation. 

Therefore, if there's an inevitable gap in what a general-purpose software offers, ensure it's a gap you can bridge with custom-built integrations, and weigh that against the inherent advantages of crafting a bespoke solution from the ground up. 

The decision between purchasing off-the-shelf and building a custom system is not just about immediate needs but also about envisioning the future trajectory of your business. As you stand at this crossroads, consider not only the present-day efficiencies but also the long-term strategic goals, ensuring that your choice today propels your business forward in the years to come.
