"We manage 120 parent SKUs on Amazon and Walmart. Our catalog was constantly hit by suppressed search tags and broken variations. My SageDoer VA updates flat-files daily, fixes stranded FBA inventory in hours, and freed up 20 hours a week for brand growth."

Tyler Caldwell

Director of Marketplaces, Peak Consumer Brands (Austin)

"FBA lost-inventory claims were falling through the cracks. In their first 60 days, our assistant audited shipment reconciliations, submitted proof of delivery paperwork, and recovered $18,400 in direct Amazon seller reimbursements."

Rachel Mercer

VP of Operations, Horizon E-Commerce Holdings (Miami)

"I used to hire freelance listing techs on Upwork who had zero idea what an FNSKU was or how to appeal a hijacked ASIN. SageDoer gave me a dedicated assistant and a free Project Manager who know Seller Central inside and out for $6/hr."

David Kramer

Founder, Kinetic Home & Kitchen Goods (Los Angeles)

"Our Amazon PPC ACoS dropped from 38% down to 24% because my VA runs search term mining in Helium 10 every morning, negates wasteful spend keywords, and adjusts bids within our target guardrails."

Frequently Asked Questions

Realistic answers for Marketplace Managers, Amazon Brand Leads, and E-Commerce Directors delegating channel production.

You never need to give away your primary master login credentials. Amazon Seller Central and Walmart Marketplace both provide granular User Permissions (Secondary User Accounts). Your VA is granted secondary access limited strictly to the required departments (such as Inventory Management, Advertising, and Case Log management) with zero access to your corporate bank deposit methods or disbursement accounts. All third-party tool logins (Helium 10, Perpetua, Keepa) are securely delegated via encrypted password vaults (1Password, Bitwarden).

Yes. Our marketplace VAs understand standard Category Inventory File (flat file) templates: mapping parent-child variation themes (Size, Color, Pack Count), managing update/partial-update attributes, auditing error feed processing reports (such as 8541 matching errors or 8007 missing child errors), and updating backend search terms, bullet points, and browse node classifications safely.

Every SageDoer Virtual Assistant and Project Manager signs comprehensive Non-Disclosure Agreements (NDAs). We adhere strictly to zero-trust security procedures: password delegation via encrypted vaults, clean-desk policies, and role-based permissions without export rights for sensitive customer data or private supplier costs. Your sales volume, supplier invoices, and profit margins remain 100% confidential.

Yes, 100%. You pay strictly for the actual working hours logged by your Marketplace Virtual Assistant ($6/hr for full-time or $7/hr for part-time). The dedicated Project Manager's daily quality checks, listing feed audits, onboarding guidance, and operational oversight are provided completely complimentary with 0% platform markups.

Yes. Marketplace operations naturally spike during key promotional windows: Q4 Black Friday/Cyber Monday rushes, Prime Big Deal Days, spring category resets, and major FBA cut-off inventory deadlines. You can begin on Part-Time (20 hrs/week), scale up to Full-Time (40 hrs/week) during peak sending months, or adjust hours smoothly with your dedicated Project Manager with zero lock-in contracts.
