Pricing
The Summary of any Ad system is free, without signing up. A Subscription to a Company gives the full Partner report of each of its Ad systems and Monitoring: every domain whose ads.txt does not confirm one of its Sellers, with the line that fixes it, checked again every week with what broke and what was fixed.
A Subscription, by the Company's size
| Size | Sellers with a domain | A month | A year, paid upfront |
|---|---|---|---|
| Small | up to 1,000 | $149 | $1,490 |
| Mid | up to 5,000 | $299 | $2,990 |
| Large | more than 5,000 | $599 | $5,990 |
A year costs ten months. The size counts the Company's Sellers with a domain over all its Ad systems, in their latest Runs, and changes only when the Subscription renews. The page of each Ad system shows its Company's size: find yours. No refunds but those the law requires.
Early access
A Subscription started by 31 March 2027, or until early access closes, pays half its price for its first 12 months, then the price of the day it started, for as long as it lasts.
Starting a Subscription
Payment by card opens in December 2026. Until then, write to hello@chainofsale.com with your Ad system's domain, and we start your Subscription.
