How does someone know they are getting paid for *all* the registrations that Kagi receives?
Ultimately the only way for an author to know for sure that they are getting paid for all the registrations is to audit Kagi. The ability to audit Kagi is part of the agreement between the author and Kagi.Otherwise, "Enlightened Self-Interest" is the best reason for Kagi to make sure that authors get all the fees from their registrations. If Kagi was skimming payments, someone would eventually notice, word would make it to all authors represented by Kagi, they would cancel their agreements, and Kagi would then cease to exist because without the authors, there is no Kagi.
The alternative to enlightened self-interest is for the author to provide a unique registration code for each payer and to be the only source for that registration code. Thus, if Kagi took someone's money and did not provide them with a code, the user would immediately complain and the author would quickly hear about it.
A more realistic problem is how does an author know that they are receiving a copy of all the email sent to payers and copied to them. The internet does eat email messages. To solve this, Kagi stamps each payment for a specific author with a sequence number (SQNM).
There is a sequence number associated with each software payment and the sequence number increases with each payment of that specific software and then rolls over back to zero when the maximum number is reached. An author should receive one email per sequence number. If a sequence number is skipped, the assumption should be that the internet did not deliver an email. In that instance, Kagi can resend the email(s) to the author.
The SQNM numbers appear in the email reply to the payer. At the end of each "blurb" that is placed in the email is:
SQNM-"blurb name" ####
where blurb name is the name we have assigned to the text message sent to your payer and #### is a four digit number that increments each time we send out that blurb.
