Why PlyOps exists
3D print sellers often hold product information in spreadsheets, slicer folders, marketplace drafts, bookmarks, and memory. The same details are copied repeatedly, and variants drift apart.
PlyOps turns that work into one structured product library that remains useful before any marketplace account is connected.
Rules PlyOps keeps
The free plan must remain useful, generic export must remain available, and connected actions must remain reviewable. PlyOps does not silently publish listings, overwrite important product fields, or use listing links as live inventory control.
What paid plans add
Cloud pays for hosted storage, backup, and sync. Connect adds marketplace imports, matching, preparation files, drafts, and confirmed updates. Each integration lists the exact actions currently available.
Common questions
Is PlyOps an inventory or accounting system?
No. PlyOps includes seller-oriented stock counts, locations, labels, and scanning, but it is not an ERP, an accounting ledger, or a system that manages live marketplace quantities.
Who is PlyOps for?
PlyOps is designed for 3D print sellers and makers who need one reusable source for product details across production, packaging, pricing, and marketplace preparation.
Can PlyOps be used without a paid plan?
Yes. PlyOps Free includes browser-local product records, generic CSV export, and JSON backup. Paid plans add hosted storage, sync, marketplace imports, matching, drafts, and confirmed updates.
