Why our hybrid SaaS model offers the best of both worlds for tax compliance

In today’s cloud-first world, businesses are often forced to choose between a rigid multi-tenant SaaS model and a more costly single-tenant setup to meet their compliance, performance, or customisation needs.

At Innovate Tax, we believe you shouldn’t have to compromise. That’s why we’ve developed a flexible hybrid SaaS architecture that gives you the power of both.

This approach was shaped by extensive work with clients in high-volume, data-sensitive industries. These sectors demand exceptional levels of data ownership and protection such as banking, telecoms, and insurance – where data ownership and protection are critical.

Being able to provide these organisations with deployment flexibility – without sacrificing performance, compliance and most importantly, security – has been essential to delivering real value.

Whether you’re a multinational corporation with strict data governance policies or a fast-moving business looking to get started quickly, our solution adapts to your needs – not the other way around.

And thanks to our unique design, we can seamlessly move clients between deployment formats – multi-tenant to dedicated, or vice versa – whenever their needs change. This ensures long-term flexibility without disruption.

Platform architecture in action

Our hybrid architecture is not just a technical concept – it’s the foundation that powers everything we do.

Across our application suite, we apply the same principles of localised processing, intelligent separation, and strict data control. This approach ensures that your data stays under your ownership, while enabling secure and efficient use of shared services where needed.

For example, in one application, VAT number validation is performed within your own environment. The system checks format, structure, and duplicates locally, and only sends the VAT number itself – without context – to a centralised verification hub for official verification.

Similarly, in our client tax team task management application, internal tasks are handled entirely within your instance, with only the support tickets you raise with us passed to our central system so we can both see and update the ticket.

These are just two examples of many processes that follow the same principle. Our entire platform is designed around this flexible, privacy-first model.

Whether you’re dealing with validation, workflow, reporting, or integration, you benefit from the same scalable architecture that keeps sensitive operations local, while offloading only what’s necessary.

In this way, our approach shares similarities with edge computing: instead of pushing all processing to a centralised system, we distribute processing closer to the source.

But rather than requiring clients to manage their own infrastructure, we provide a form of localised SaaS.

This middleware-style design allows each client instance to perform core processing functions independently, with our centralised system supporting only those tasks that cannot be done locally – delivering the benefits of edge without the complexity of traditional edge deployments.

This design gives clients in high-volume, regulated sectors the ability to adapt quickly, protect their data rigorously, and transition between environments as needed – all without compromise.

Privacy-first by design

Our design ensures:

• Minimal data exposure – Only what’s strictly necessary is passed to our master system.
• Siloed processing – Your environment, your data, your rules.
• Audit-ready transparency – All checks are logged and traceable for compliance.

This model gives you the efficiency of a cloud platform with the privacy and control of an isolated system. For organisations subject to data residency rules, or those concerned about cloud vendor lock-in or compliance with regulations like GDPR or DAC7A tax directive in the EU that requires digital platform operators to report personal and business information about their providers to tax authorities., this is a game-changer.

Your data, your control, your intelligence

By choosing your own instance, you gain full control over your data – you know exactly what’s stored, and so do we.

That certainty enables powerful integrations: we can expose APIs that let you connect your own applications, reporting tools, or analytics engines directly to your centralised dataset.

Take our award-winning LimeLyte® Entity Manager as an example. It allows you to record and track every customer and supplier across all your systems.

You can also include your own legal entities, bank accounts, and even individuals with VAT numbers.

Every change – from a name or address update to a new VAT number linked to an account – is captured, versioned, and ready for audit or real-time validation.

This centralised, client-owned data hub becomes a powerful resource: use APIs to verify entries across platforms, alert users to duplication (e.g., if a customer already exists in SAP while entering it in Salesforce to avoid account overlap issues), or validate new entries against your own golden records.

Our Plugin and APIApplication Programming Interface. APIs are an accessible way to extract and share data within and across organisations. also go further – not just validating tax numbers, but cross-referencing them with your existing data to flag potential duplication, letting you know the source and name of the potential duplication.

This is data infrastructure that works for you: centralised for consistency, local to your system for security, tracked for audit, and accessible however you need.

And unlike typical SaaS, where you surrender visibility and integration flexibility, our model gives you ownership and oversight from day one.

Why this model works better than traditional SaaS

Let’s be honest – most SaaS platforms are either too centralised (one-size-fits-all and designed to maximise the revenue of the platform provider) or too expensive (fully customised deployments).

Our architecture solves this by giving you:

• Faster performance through localised processing
• Higher security by limiting shared system exposure. While we maintain and support the application, access is fully controlled by you through your own VPN, ensuring complete authority over when and how access is granted.
• Audit-ready compliance with minimal external data movement
• Flexibility to start in a multi-tenant space and migrate to a private instance if needed
• Cost-efficiency with no duplicated logic or unnecessary infrastructure – our application design and update process is consistent across both single-tenant and multi-tenant deployments. This means we apply improvements and fixes in exactly the same way, regardless of how a client chooses to deploy, ensuring rapid rollout and consistent experiences without added cost or complexity.
• Plugin-based processing directly from user screens (designed to appear as part of the source system for a seamless user experience), avoiding the need to pass data back to source systems – delivering 100% protection to the original system with no custom development required to call, display, or store API results

It’s SaaS, but smarter. Distributed where it counts. Centralised only where it makes sense.
