For many years, FWP has probably tried hard to do the best with what they had. I believe the "ALS" system was built and maintained by state workers. It may not be easy to simply add a "harvest reporting module" to that system. I'd bet it would cost more that it would save by eliminating callers.
Harvest reporting is one of those "is the juice worth the squeeze" things.
Apples to oranges - NY is NOT self-funded by license sales. Long ago, they were able to "contract out" the entire licensing system which now works great. NY issues 2x more hunting and 9x more fishing licenses than MT. They spend about $3,000,000 a year just on the sporting license system that includes harvest reporting by phone, web or app.
Mandatory harvest reporting since 2000. No automatic penalties for not reporting and the ECOs don't really issue a lot of tickets for non-reporting. It took several years for the reporting rate to level off and provide "more accurate" estimates.
