Pricing.
Transparent. Stated up front. Nothing hidden.
For buyers
| Fee | Amount | How it appears |
|---|---|---|
| Platform support fee | 0.5% | Separate labeled line item at checkout |
The platform support fee is added to the order subtotal at checkout. It is never rolled into the item price.
Example
A $100 item costs $0.50 in platform fees. Your total is $100.50, plus any shipping the seller sets. That is all.
For sellers
Transaction fees
| Tier | Trailing 6-month GMV | Transaction fee | Seller keeps |
|---|---|---|---|
| Apprentice | $0 – $5k | 5.0% | 95.0% |
| Journeyman | $5k – $25k | 3.5% | 96.5% |
| Artisan | $25k – $100k | 2.5% | 97.5% |
| Master | $100k+ | 1.5% | 98.5% |
Tiers are based on trailing 6-month GMV, evaluated monthly. Upgrades take effect immediately when a threshold is crossed. If volume drops below the current tier's threshold, the tier adjusts at the next monthly evaluation. No application required.
Membership
Monthly flat fee for platform access
| Tier | Monthly membership |
|---|---|
| Apprentice | $0/mo |
| Journeyman | $15/mo |
| Artisan | $35/mo |
| Master | $79/mo |
Membership tier is determined by the same GMV thresholds as transaction fees. It never affects search ranking, product visibility, or browse ordering.
Founding offer
First 6 months free for new sellers. Annual prepay: 2 months free.
If membership lapses, there is a 7-day grace period. After that, listings are hidden and cart adds are blocked until membership is renewed.
GMV calculation: GMV is the order subtotal only. The buyer platform fee (0.5%) is never included in GMV calculations and does not affect a seller's tier advancement.
