Contract Costing, Purchasing & Sales

Pegasus CIS in the cloud

Pegasus Business Cloud enables you to access CIS online, at the office or on mobile devices, anytime, anywhere when it suits you.

Integrated Accounting

It’s easy to link Pegasus CIS to your accounting system. It integrates with Pegasus Opera II, Pegasus Opera 3, Sage 50 and Sage 200.


Pegasus CIS is a software solution specifically designed for the construction and contracting industries. Not only will it make you fully compliant with the taxman, it'll also bring astonishing efficiencies to your contract management.

When you consider that the average construction project suffers 150% cost overruns and completes more than 175% late, there’s clearly a great need for software that can help you to deliver projects on time and within budget – and transform your profitability.

Pegasus CIS provides complete control over all aspects of contracts management, from costing and timesheets through to payment applications, VAT invoicing and cash receipt matching. Fully integrated to the Sales, Purchase and Nominal Ledgers, Cashbook and Payroll, Pegasus CIS conforms to the requirements and regulations of HMRC's Construction Industry Scheme.

Pegasus CIS recognises the complex business requirements of the construction sector, offering an unparalleled level of management control over contracts and subcontractors. It integrates with Opera 3, Opera II, Sage 50 and Sage 200.
