since I started with WHMCS Development and pushing the HEXONET Modules (the so-called ISPAPI Branch), I wondered why WHMCS did not consider integrating Domain Trades. Why is is necessary to know about Trades? Whenever you change the Registrant Contact Data, it may result into a Trade - somehow comparable to the IRTP. Mainly caused by changing Organization / First- /Lastname / Email Address but this also depends a bit on the underlying TLD/registry provider
* Depends on the TLD, if a trade is required or not for the change of registrant
* Trades are sometimes NOT free of charge (the pain in WHMCS and the main difference to IRTP)
* All Registrar Modules I ever saw have not covered that case and have this either not working - so you have to contact support or they have this working. In both cases the costs are NOT invoiced in direction of reseller's clients. Just the reseller pays for it.
* Trades also require a non-realtime processing (has to be accepted)
We actually log Trade Costs into the System Activity Log for Reseller's Rerference.
Please consider that topic for a future release.
