SizeRun keeps your stock in sync across marketplaces. List in bulk, reprice with profit guardrails, and when a pair sells, every other listing updates automatically — so you never sell the same pair twice.

Stop updating three tabs and a spreadsheet every time something sells.
Track every pair by style code, size and condition. See available, reserved and sold quantities at a glance. Import from CSV.
Select inventory and list it on multiple marketplaces at once, with a different price for each platform.
When a pair sells on one platform, SizeRun adjusts or removes your listings everywhere else. Duplicate notifications never double-count.
See estimated payout and profit for every listing after marketplace fees, shipping and your cost.
Bulk price changes today; rule-based repricing with a minimum payout, profit floor, schedule and pause switch.
If a marketplace rejects a listing or a sync fails, you see exactly why — and retry with one click.
Connect your own seller accounts. Your listings and payouts stay under your name.
Marketplace availability depends on each platform's API access and terms. We'll only enable an integration once it is officially supported.

No. SizeRun is software. You sell on your own marketplace accounts and receive payouts directly from them. We only charge a flat subscription fee.
Each pair has one quantity shared by all your listings. When an order comes in, SizeRun records it once and then lowers or removes your other listings for that item. If a marketplace call fails, it retries and shows the issue in your dashboard.
We connect through each marketplace's official authorization where available, store credentials encrypted, and you can disconnect at any time.
Yes. Cancel from the billing page and you keep access until the end of the period you've paid for.
