Centralized Reporting & LP

TransAction+ Reporting Services manages the polling and posting of transaction details from your stores or web/catalog business in a Central Electronic Journal. The first solution built on top of this centralized reporting solution is Loss Prevention (LP). We partnered with one of the leading LP Practices in North America to refine and implement a solution that can be used to focus your LP efforts where they are most important.

Reduce Time Searching for Transactions

Our reporting solutions allow you to drill down to the lowest level of transaction information – and this same detailed view is available in the Central Electronic Journal. You can easily search and find transactions – whether as part of a chargeback investigation or due to questions from the sales audit. Having this information centrally available reduces costs and time involved in researching transactions.

Safeguard Returns

While everyone has a posted returns policy, fraud and inconsistent implementation of the policy lead to customer service issues, errors and theft. The same data that supports the Central Electronic Journal allows us to “systemize” your return processes by validating receipted returns, tracking customers abusing non-receipted returns, enforcing your rules for lowest selling prices and sending checks and in-store credits.

In-House Gift Cards

TransAction+ Card Services provides a fully functional in-house gift card program that is seamlessly integrated with Loyalty Services. You can utilize the gift cards for merchandise credits, automatically transfer points so they are available to spend, and even use the card to control discounting and monitor for fraud.

Electronic Payments

An Advanced Solution for Credit, Debit, Gift, Loyalty and Check
Supports All Major Payment Processors

TransAction+ Payment Service provides Payment Optimization capabilities and support for all the major payment processors and networks – so you and your customers are guaranteed to enjoy the best combination of service and price.

Comply with Latest Industry Regulations

We are constantly updating the product to support the latest industry requirements and mandates. We were one of the first to certify for both E2EE and EMV on multiple payments platforms and devices, and our customers benefit from early deployment of these key enhancements.

PA-DSS Certification

TransAction+ has earned the PA-DSS Certification and GK Software has extensive experience partnering with retailers large and small to assist them in their own certification process. You can trust TransAction+ to be compliant with all security standards.

Non-Payments Customer Interactions

Modern retailing demands that every touchpoint be utilized to maximize speed and enhance the customer experience. TransAction+ enables the use of the payment for e-receipt prompting, loyalty interactions, email capture and confirmation, survey responses, and a host of other non-payment functions. These interactions can be adapted rapidly in response to changing customer demands and marketing initiatives, increasing the agility of your retail business.
