Pegasus Opera 3

Reliable ERP for businesses that need systems which work, not systems which break.

What is Pegasus?

Pegasus is a long-established, UK-based business management software developer. The product is now in its third major iteration - Pegasus Opera 3SE. Acquired by Infor (a large US-based consolidator of software products) in 2000, several thousand UK businesses use Pegasus software.

What does Pegasus Opera do? This ERP system includes the finance, sales order processing, purchase order processing, stock management, and payroll functionality that businesses need. Pegasus Opera 3 is designed for mid-sized organisations who've outgrown basic accounting software.

Why Choose Pegasus Rather Than Business Central or NetSuite?

Because you or key members of your team already know the Pegasus Opera 3 software. That familiarity matters - it builds confidence, accelerates deployment, and reduces training costs.

Five capabilities that make this ERP system work for growing businesses:

Everything Talks to Everything:

Finance, stock, orders, and payroll work from the same data. No more manual exports or spreadsheet reconciliation nightmares.

Compliance Without the Headaches:

Built-in VAT, statutory reporting, and audit trails. Stay compliant without hiring compliance experts.

Know What's Happening Now:

Real-time cash flow, profitability, and performance data. Make decisions based on current information, not last month's guesswork.

Grows With Your Ambitions:

Handle more transactions, users, and complexity without replacing your entire system.

Stop Chasing Invoices:

Automated AP processing and approval workflows. Your finance team can focus on analysis instead of data entry.

Which Pegasus Partner Should I Work With?

When choosing the right partner for your Pegasus Opera 3 implementation, look for two things:

Real Help or Empty Promises?

References might sound impressive, but finding out how good a partner's Pegasus Opera 3 support is comes directly from customers. The best way to determine support quality is by asking about the partner's NPS score.

Quality Pegasus Opera 3 support separates successful implementations from expensive disasters. Your finance team needs responsive help when they need it, not someone reading from a script days later.

Brady Bags Gains Complete Visibility with Pegasus Opera

Brady Bags adopted a new business system, but it proved to be unfriendly, error‑prone, and lacked safeguards. We implemented a brand‑new Pegasus system from the ground up.
Opera on Pegasus Business Cloud enabled remote access and 24/7 visibility. Pegasus was configured to meet the needs of both manufacturing and accounting departments.

After having experienced other providers, I can honestly say that working with TSG and using the Opera system is by far the most beneficial and pleasant experience that we at Brady Bags have had. The team are extremely supportive, and the systems are smooth and offer Brady the opportunity to grow and make our every day working easier and more effective. We look forward to continuing expanding our systems with the help of the TSG team.
