Software that, at a minimum, provides tracking and reporting of commission-triggering actions (sales, registrations, or clicks) from affiliate links.
Affiliate merchants that run 100% in-house affiliate programs need to find–and possibly customize–affiliate software to handle transaction tracking and reporting. Solutions range from free and almost-free scripts to expensive software packages.
Affiliate merchants that use affiliate networks do not have to directly manage the affiliate software, although integration must occur between the affiliate merchant’s site and affiliate network’s software.
