Bespoke software creation

Off-the-shelf tools might meet some of your needs, but real business value often comes from processes unique to your organisation. Bespoke software integrates those processes seamlessly, helping you work smarter, not harder.

Our process begins with a detailed specification phase, mapping your goals and defining your vision. The result is a reliable, tailored solution delivered on time and on budget.

Whether you need automation tools, databases or portals on site, in the cloud or on the web, we build secure and efficient systems that evolve with your business.

Investing in bespoke software gives you a competitive edge through stronger business intelligence and more efficient processes. The benefits are significant when every decision is backed by CETSAT’s detailed process mapping and analysis.

We deliver solutions that optimise efficiency and increase productivity. With a proven track record of delivering on time and on budget, we work across a wide range of technologies to ensure the most relevant and cost effective approach.

Ecommerce solutions

We design and build ecommerce websites that are fast, secure and focused on conversion. Whether it’s WooCommerce, Shopify or Umbraco Commerce, our team delivers platforms that are easy to manage and aligned with your goals.

Every site is mobile responsive, SEO-ready and integrated with your existing systems. From payment gateways to stock control and customer accounts, we make sure everything works together without adding complexity for your staff.

With ongoing hosting and support, your store continues to perform as your business grows.

Website design

Whether you’re building your first site or re-imagining your brand presence, our team combines design, copywriting and development to create websites that work.

Each build includes advanced SEO features and can integrate with your inventory, accounting or CRM systems. Hosted securely and monitored by our in-house professionals, your website performs reliably and looks the part.

Secure by design

All our software and websites are built with security at their core. We use proven methodologies and regular updates to minimise risk.

Most of our development takes place on Microsoft Azure, providing a secure, flexible and resilient environment for your business critical applications. If you prefer to host on your own infrastructure, we can deploy there too, but cloud hosting means one less server to maintain, patch and back up.

Reporting solutions

If your systems don’t produce the insights you need, or your new platform won’t talk to your old data, we can help.

We enhance the reporting capabilities of your existing software, integrate disparate systems and deliver dashboards that make your data easy to interpret. The result: greater visibility, reduced manual effort and better decisions.

Search engine optimisation and keywords

A great website deserves to be seen. Search standards change constantly, but our team keeps ahead of the curve to ensure your content performs.

We help you climb the rankings, reach a larger audience and stay ahead of competitors. We can also manage your Google Ads campaigns to drive qualified traffic and improve lead generation.

Entry level low code applications

Using Microsoft Power Platform within Microsoft 365, we create low or no code automations and applications that boost productivity using tools your team already knows.

We also provide training to help your staff identify opportunities for improvement and drive their own efficiency gains.

Artificial Intelligence and Automation

At CETSAT, we use AI to support our developers, not replace them. It helps us work smarter, automate repetitive tasks and improve accuracy across projects, while our team remains in control of every decision and line of code.

We have years and years of expertise that simply cannot be replaced by AI, at least not yet. Our people bring the context, judgement and creativity that technology alone cannot replicate.

AI assists with things like testing, data analysis and code generation, but it is always guided by human expertise. This ensures that every solution we deliver is secure, explainable and aligned with your goals.

By combining intelligent tools with experienced developers, we create software that is both innovative and reliable.
