Grading Submission Manager: An organizer for serial submitters tracks PSA, BGS and CGC submissions, current statuses, declared values and return costs.

Scrape public grading status pages, build a per-card timeline view and charge a monthly fee to heavy submitters.

Why it can work: Serial submitters juggle dozens of cards across graders with opaque statuses; a unified tracker is a daily-use tool for exactly the customers who spend the most.
