Software Development, IT Consulting and Financial Services Platforms for your Business

As a full-service Software Development, IT consulting and Financial Services platform provider, ONTOP Systems offers the following services:

Strategies and Planning

Getting reliable results from your business and financial services platform requires in-depth planning, development, installation and management.

Our team of experts understands every aspect of business and financial services — from lead generation, through point of sale, payment, credit card, consumer financing and receivables management.

We also offer comprehensive accounting and IT security competencies to track your finances and protect your enterprise.

Credit Card Merchant Processing Services

Our relationship with TSYS Acquiring Solutions allows us to provide our clients with a Tier 1 Merchant Credit Card Processing platform.

Not only do we offer the best rates available anywhere, our technology integration with the VisaNet system provides fast, safe and secure access to the worlds largest merchant acquiring provider.

TSYS was built by the same people who run VISA and the VisaNet platform, so we're working to support a proven winnner.

Credit Card Processing just took a leap forward with the release of Summit Paylex®. With High-speed connectivity to the TSYS processing backbone, the industry standard, ONTOP Systems has joined elite company in merchant processing.

What differentiates us from all the rest is the Summit Account Software "Platform".  Summit underpins nearly everything we do, especially our merchant processing technologies.

The merchant processing functions in Summit 9.2 were certified on September 19, 2002.  We became one of a handful of CRM/ERP Business Management software providers to include an all-Internet platform for Credit & Debit Card processing.

Transaction speeds are FAST.... so we time them to the hundredth of a second! We've seen 1.05 seconds start-to-finish, but your mileage may vary. Give us a call and let us know just how fast, FAST is.

PCI Assessments

From the world's largest conglomerates to the smallest retail stores, compliance with the PCI Data Security Standard (PCI DSS) is vital for all merchants who accept credit cards, online or offline.

Keeping your customer’s payment card data secure is also vital in today's competitive business environment.

ONTOP Systems can help you determine the specific compliance requirements that must be met.

We're here to help merchants incorporate the PCI Security Standards through auditing, consulting, education and training.  We can help you protect payment card data according to the PCI Security Standards.


Installing and testing your new platforms can cause nightmares for even the most seasoned IT professional. ONTOP Systems, Inc. thoroughly tests and re-tests all devices and software prior to your switch-over date. You can rest assured that from the moment you connect your new system, all data and communications will function as you need it to.
