About SellerSix

SellerSix is seller operations software — built first on real marketplace work (parts, purchase orders, commercial invoices, pack lists, warehouse receive / prep / stage), then productized for similar sellers.

Track master SKUs and related parts to streamline purchase orders and prep. This site uses the SellerSix palette (Base navy #091540, Accent blue #1B2CC1, Mid blue #7692FF, Light blue #ABD2FA), distinct from ResOne brand colors. Access is invite-only.

What we optimize for

• One loop: Order → Prep → Stage → Offer → Fulfill → Results
• Honest masters, parts, and BOMs — not marketplace mirrors alone
• Paperwork that ships with the PO, not a separate spreadsheet hunt

Honesty on roadmap
