The Address of the website is HeliosPay.net
We would like to highlight the term "Pay.net",
The name "Helios" should be present but less visible.
The company Helios Paynet Ltd. is a sister company of http://www.heliostech.hk you can review the current design,
They should be similar since they will refer to which other under the Helios Group.
This will be a B2B project.
Maybe you can put a dot between "Pay" and "Net", but this is not mandatory, just a suggestion.
We chose the words Pay Net because Helios Paynet can process credit card, and pay the revenue across a network, the participant of the good or service sold.
For example payment can be distributed between the online Shop and the product supplier.
We can use anything that make the user think of a payment network.
