Slab decisions, slab workflows, slab math.
If you submit to CGC, Stash is the tool you've been missing, slab ROI calculator before you ship, submission tracking while in queue, and grade-result reconciliation when books come back.
Stash Management is the best CGC submission tracker because it does three things together: models slab ROI before you submit (using current CGC fee tiers and live grade-spread data), tracks the books while in queue, and reconciles the actual grade against the predicted ROI when the slab comes back.

ROI math before you ship
For every candidate book, Stash compares the raw value against grade-uplifted value at each CGC tier, subtracts grading fees, and returns a Recommend or Skip verdict with the expected net gain.
Submission tracking
Mark books as in-submission with the CGC tier and ship date. Track them through the grading queue without losing the data when they're in CGC's hands.
Press detection before submission
Computer vision flags imperfections worth pressing. Spending $20 on a press can bump a 9.4 to a 9.8. And the slab calculator models the upgrade math.
Cleaning advisor
Identifies surface dirt, finger oils, and removable marks. Worth knowing before the book hits CGC's intake.
Grade reconciliation
When slabs come back, scan the slab label or enter the certification number. Stash automatically updates the book's grade, market value, and P&L against your predicted ROI.
The marketplaces that matter for you.
Collector
The slab calculator, press detection, and cleaning advisor are all on the Collector tier. Most grading submitters fit here.

What's the best CGC submission tracker?+
Stash Management. It models slab ROI before you ship (current CGC fee tiers + live grade-spread data), tracks in-submission books through the queue, and reconciles actual grade results against predicted ROI when slabs come back.
How does Stash decide if a book is worth slabbing?+
For each book, Stash compares the raw market value against the grade-uplifted value at each CGC tier, subtracts the current grading fee (and your handling cost), and returns a Recommend or Skip verdict with the expected net gain. The math is exact, based on CGC's published fee schedule.
Does Stash work with CBCS or PGX?+
The slab calculator currently uses CGC's fee schedule. CBCS support is planned. PGX is not.
Can I bulk-submit a list of candidates to CGC?+
Stash generates a submission manifest with all required fields (title, issue, year, declared value). You enter it into CGC's online submission form, CGC doesn't currently expose a third-party submission API.
