Scaling your SaaS to enterprise: What does it take?

Scaling SaaS products for enterprises is easier said than done. If your SaaS team is planning to expand into the enterprise customer segment, there’s a whole new set of IT, admin, and security capabilities you’ll need to tackle before getting started.

Enterprise organizations evaluate SaaS products very differently compared to smaller businesses. SMBs typically look for products that solve their core challenges, are user-friendly, and offer affordable, transparent pricing. More than half the battle is won with a high-quality product that’s easy to use.

However, scoring high on “product readiness” alone isn’t sufficient for you to land enterprise deals. You’ll need to demonstrate that your product is “enterprise ready” if you want to acquire larger organizations.

What does "enterprise readiness" mean?

Large companies go through a rigorous software evaluation process involving stakeholders from various teams:

• Business teams assess the core functional features and use cases and act as the internal champions of SaaS products. Examples: Sales teams assess CRM software, HR teams evaluate HRMS solutions, etc.
• The Chief Information Officer (CIO) and IT teams look for IT and admin capabilities such as user authentication, user provisioning, fine-grained access controls, and audit logs.
• The Chief Information Security Officer (CISO) and InfoSec teams evaluate if the SaaS product meets security and compliance requirements.

Meeting the needs of these different stakeholders is crucial if you plan to expand into the enterprise market. If your SaaS product doesn’t meet these criteria, you’re unlikely to get through the evaluation process, thereby losing your opportunity to operate in the enterprise market.

In other words:

Your SaaS product can be considered enterprise ready only when it meets all the requirements of Business, IT, and InfoSec teams of a large organization.

What are the requirements for enterprise readiness?

For SaaS startups in their early or growth stages, scaling into enterprise feels like venturing into uncharted waters.

Knowing the complete list of enterprise expectations ahead of time will help you plan your SaaS product’s path to enterprise readiness and execute the roadmap more effectively.

Broadly speaking, the enterprise requirements for your SaaS product can be grouped into the following categories:

• Workspace management: The ability to manage users/collaborators and test/deploy features
• Data & analytics: Features that enable data-driven decisions
• IT & admin: Centralized controls for authentication & access management
• Security: Capabilities that make the data and app secure
• Integrations: Automations that connect and enable internal tools to work together
• Availability: Uptime monitoring and disaster recovery

At first glance, this list seems simple enough — which is why many SaaS engineering teams default to building these enterprise-level features themselves. For example, they might estimate that it will only take a couple of sprints to build authentication capabilities.

But this cannot be farther from the truth. We spoke with 50+ SaaS teams to understand how they’re scaling into enterprise, and almost every team greatly underestimated the time and complexity involved — leading to long, frustrating delays.

Here’s how the full list looks once you peek under the hood and look at the requirements under each category.

Now that we’re aware of the exact enterprise requirements, let’s explore your options for implementation.

How can my SaaS product become enterprise ready?

These functionalities, while not part of your core SaaS product, are absolutely essential for expanding into the enterprise customer segment. If you’re looking to make your SaaS product enterprise-ready, here are your choices:

Option #1:  Build in-house

Building these capabilities internally gives your engineering team complete control of the codebase and the ability to fully customize these features.

However, while many SaaS teams often default to developing these capabilities in-house with dedicated teams, it comes with several major business risks:

• Distracts your product & engineering teams from building your core SaaS product: Developing these capabilities internally diverts your team’s focus and impacts your core product innovation.
• Increases time-to-market and cost: Building and stabilizing these capabilities takes 4+ quarters as well as a dedicated team of 4-5 platform engineers. Additionally, the substantial time required for hiring the team further slows down your SaaS product’s velocity towards becoming enterprise-ready.
• Deals slip away: Enterprise customers simply won’t wait for your SaaS product to catch up to the expectations they have around admin and security capabilities. Your competitors are going to swoop in and capture prospective customers while you’re held up here.

This option can be effective if you’ve secured a significant foothold in your market, face minimal threats from the competition, and manage a large engineering function with dedicated teams for developing platform capabilities. But if your SaaS company is in the early to growth stages, building these features in-house is incredibly risky.

Option #2: Leverage open-source software

Open-source libraries enable your team to quickly launch the first version of these capabilities and test the waters. Since open-source is free, there’s no need to worry about additional software or subscription costs.

However, you will need to consider the following:

• Open-source libraries are general purpose toolkits — they’re not built for specific, complex SaaS use cases. Your engineering team will need to understand their architecture and dig into the codebase in order to customize it to your business needs and customer workflows.
• Your team will still be responsible for ongoing engineering overhead like debugging, creating admin portals, change management, maintaining security posture, audit logs, data security, compliance, hosting and managing infrastructure, scaling, and other upgrades.

Time to market seems quicker with open-source. However, the added customization, engineering, design, and infrastructure work is usually grossly underestimated. This defeats the purpose of using open-source tools in the first place. With regards to developing enterprise capabilities, we don’t consider this to be a very effective option.

On the other hand, if you are looking for boilerplate code that you can customize and are willing to invest the necessary time and resources, this might be the right option for you.

Option #3: Use third-party platforms

Transitioning into the growth stage, SaaS companies face the dual challenge of strengthening their core product and expanding to the enterprise segment. Regardless of where your company is in its growth journey, developing these enterprise capabilities internally diverts your engineering team’s focus and impacts your core product’s innovation.

In the last few years, modern platforms have given engineering teams the flexibility and freedom to focus on their core SaaS product and not be burdened by the overhead of building additional capabilities. Many engineering teams today use purpose-built products such as Twilio for communications API, Sendgrid for email API, and Sentry for app monitoring.

Similarly, B2B SaaS companies would benefit from third-party products that offer enterprise capabilities such as authentication, user management, authorization, audit logs, feature flagging, and more. For example, a SaaS-first authentication platform would:

• Significantly reduce your time-to-market with pre-built authentication and user management components
• Solve enterprise use cases such as single sign-on, modern auth methods such as passwordless authentication, admin portals for config, pre-built login box, customization options, CRM integrations, and analytics tools
• Reduce the burden on your product and engineering team by allowing them to focus on building your core SaaS product

While your team will still need to spend some time learning a new tool, you’ll benefit from a multitude of pre-built capabilities, reduced engineering costs, and more peace of mind with built-in security and integrations.

Choosing the best path to enterprise readiness

The build vs. buy question is not only a technical decision but also a strategic imperative that can shape your growth into the enterprise segment.

The fact remains that using a third-party product built for SaaS products accelerates your time-to-market and allows your engineering team to focus you on your core product with minimal resources.

FAQs

What core components define enterprise readiness for B2B SaaS applications?

Enterprise readiness transcends basic product features. It encompasses a robust framework of IT, security, and administrative capabilities required by large organizations. Specifically, this involves implementing secure user authentication via SSO, automated user provisioning, fine grained access controls, and comprehensive audit logs. To successfully navigate the evaluation process led by CISOs and IT administrators, your platform must demonstrate compliance and the ability to integrate seamlessly with existing enterprise identity stacks. Failing to address these infrastructure requirements often results in stalled deals, as business utility alone cannot bypass stringent security and administrative hurdles.

Which internal stakeholders influence the enterprise software procurement process?

Navigating enterprise sales requires satisfying three distinct stakeholder groups. Business teams evaluate functional utility and core use cases to solve specific operational challenges. Conversely, the Chief Information Officer and IT teams scrutinize administrative capabilities like authentication and centralized user management. Finally, the Chief Information Security Officer focuses on compliance, data protection, and overall security posture. A successful SaaS product must provide value to all three segments. Neglecting IT or security requirements often leads to rejection during the rigorous evaluation phase, regardless of how innovative the core product features may appear to the end users.

Why is centralized authentication critical for scaling into the enterprise?

Centralized authentication is the foundation of enterprise security architecture. Large organizations utilize Identity Providers to manage user access across their entire software ecosystem. By supporting enterprise grade authentication methods like SAML and OIDC, your SaaS application allows IT admins to enforce password policies and multi factor authentication from a single dashboard. This reduces the administrative burden on your customers and significantly improves their security posture. For a B2B SaaS provider, building these capabilities into your platform is not just a feature but a mandatory requirement to move upmarket and secure high value contracts.

How should developers handle authentication for autonomous AI agents?

As AI agents and autonomous workflows become prevalent, traditional user based authentication is insufficient. Developers must implement Machine to Machine or A2A authentication strategies to ensure secure interactions. This involves using client credentials or short lived tokens to verify the identity of the agent rather than a human user. By adopting modern standards such as Dynamic Client Registration, organizations can automate the onboarding of these agents while maintaining strict security boundaries. Ensuring that your B2B architecture supports both human and agentic identities is essential for future proofing your enterprise offering in an AI driven landscape.

What risks arise when building enterprise features in house?

Engineering teams often underestimate the complexity and maintenance overhead associated with building enterprise features like SSO or SCIM provisioning. While initial implementation might seem straightforward, the ongoing requirement to support diverse identity provider configurations and security standards can drain development resources. This diversion of talent away from your core product roadmap leads to delayed market entry and increased technical debt. Leveraging a dedicated auth provider allows your team to focus on building unique value while ensuring your infrastructure meets the rigorous standards of enterprise IT and security departments from day one.

Why are fine grained access controls necessary for large organizations?

Enterprise environments involve complex organizational structures with varying levels of responsibility. Standard role based access control is often insufficient for large scale deployments where granular permissions are required to ensure the principle of least privilege. Fine grained access controls allow administrators to define specific actions users can perform on particular resources, minimizing the risk of unauthorized data exposure. Implementing this level of precision within your SaaS application builds trust with CISOs and ensures that your product can adapt to the sophisticated governance requirements typical of Fortune 500 companies and regulated industries.

What role do audit logs play in enterprise security compliance?

Audit logs provide a comprehensive historical record of all activities within a SaaS application, which is vital for security monitoring and regulatory compliance. Enterprise customers require detailed logs covering user logins, permission changes, and data access to detect potential threats and facilitate forensic investigations. Without robust logging capabilities, organizations cannot meet their internal governance standards or external regulatory obligations like SOC2 or GDPR. Providing searchable and exportable audit trails allows your customers to maintain visibility over their data and helps your product pass the stringent security reviews conducted by enterprise InfoSec teams.

How does automated user provisioning benefit enterprise IT administrators?

Automated user provisioning via protocols like SCIM streamlines the onboarding and offboarding process for enterprise IT teams. Instead of manually managing accounts, administrators can sync their Identity Provider with your SaaS application to ensure that user access is granted or revoked in real time. This synchronization significantly reduces administrative overhead and minimizes the security risk associated with orphaned accounts. For B2B SaaS companies, supporting automated provisioning is a key differentiator that appeals to CIOs looking for operational efficiency and tight integration with their existing identity and access management infrastructure.

Can Model Context Protocol servers improve enterprise AI integration security?

The Model Context Protocol or MCP provides a standardized framework for connecting AI agents to various data sources and tools. Implementing MCP servers within an enterprise context requires a robust authentication layer to ensure that only authorized agents can access sensitive data. By integrating Machine to Machine authentication and fine grained authorization into your MCP architecture, you provide a secure bridge between AI capabilities and enterprise data. This approach allows CISOs to maintain control over information flow while empowering developers to build sophisticated AI driven applications that adhere to corporate security policies and architectural standards.
