Did you know that all of our modules include a one year period of support and updates? They also include the first install and configuration, and we will also set up the necessary cron jobs.
All support is handled through our ticket platform:
http://tickets.informax.es/open.php
If after the first year you want to renew this service, which is not mandatory, contact us through our support system and we'll give you indications for it. The cost of the renewal is usually 50% of the module's initial cost. If for example you got the BigBuy importer for 135€+Iva, the renewal will cost 67.5+Iva.
We also offer phonecall support, you can get it here:
And if you need a module which is not yet done, or want to make modifications to an existing one, don't hesitate to ask.
