Marketplace accounts, kept out of the danger zone.

I help Amazon, eBay, and Walmart sellers protect their accounts, recover from performance flags, and run multi-marketplace operations with the discipline of a real operations function — not just task execution.

About

A backend operator for sellers who treat their account as critical infrastructure.

I'm Mark Angelo Dela Cruz — an E-Commerce Account Health Specialist supporting US-based sellers across Amazon Seller Central, eBay Seller Hub, and Walmart Seller Center.

My focus is the layer that decides whether a seller stays in business: account health metrics, policy compliance, unit economics, and the documentation that protects revenue when things go wrong.

I'm currently deepening my Amazon PPC and marketplace automation skills (Zapier/Make) to add profit-focused campaign management on top of this operations base.

Selected case studies

Major rescue, rapid recovery, and sustained excellence at scale.

Platform: eBay Engagement: ~3 months Result: Top Rated achieved

Major account rescue — eBay tracking compliance from 47% to 99%.

Multi-category eBay seller · automotive parts & accessories

The situation

The account arrived with Tracking Uploaded On Time at 46.71% — less than half of eBay's required threshold — and a 6.10% late shipment rate. It held "Above Standard" but was at clear risk of demotion if either metric drifted further.

The approach
  • Daily tracking validation on every order before marking shipped
  • Same-day buyer message response to protect dispute outcomes
  • Daily supplier stock checks to prevent late shipments at the source
  • Continuous feedback monitoring to catch issues early

Platform: Walmart Engagement: 30 days Result: Urgent flag cleared

Rapid 30-day recovery on a Walmart account flagged for suspension risk.

Walmart Marketplace seller · lifestyle vertical

The situation

Two performance metrics were flagged URGENT by Walmart — both at active risk of suspension under Walmart's enforcement policy — with a third trending into Monitor territory.

The approach
  • Daily tracking validation on every shipped order to lift Valid Tracking Rate
  • Same-day, structured response discipline on Seller Center messages
  • Daily supplier stock verification to prevent the cancellation cascade
  • Weekly performance review with documented action items

Platform: eBay Engagement: ongoing Result: Top Rated held

Sustained Top Rated excellence across a high-volume eBay catalog.

High-volume eBay seller · electronics & repair-parts vertical · 11,000+ items listed & sold

The situation

The account operates at high catalog volume with a constant stream of orders. The challenge isn't recovery — it's holding near-perfect metrics while traffic and conversion grow. Defect rate held at 0.00%, Top Rated status maintained continuously.

The result — traffic up, metrics held
  • Listing impressions grew +54% while Top Rated status was maintained
  • Transaction defect rate held at 0.00% across the full catalog
  • Tracking uploaded on time held above standard throughout
Operating discipline

Account health is a daily ritual, not a reactive function.

01

Tracking validation, every morning

Every order's tracking is verified before it's marked shipped — exceptions caught the day they happen, not the week the metric drops.

02

Same-day buyer response

Messages answered the day they arrive. Response discipline is the cheapest form of dispute prevention available.

03

Daily supplier stock checks

Stock verified before listings stay active. Cancellations are prevented at the supplier layer, not the order layer.

04

Weekly metric review

ODR, LSR, VTR, cancellations and feedback reviewed across all platforms. Trends documented. No surprises at evaluation.

Ready to delegate account ownership?

If your store is bleeding metrics, sitting on a flag, or you simply need an operator who treats account health as a real risk function — message me with your situation. I'll review the case before we discuss terms.

Note: case studies above are from accounts I manage, with seller-identifying details kept confidential. I work with U.S., U.K., and Australian time zones. I observe the Seventh-day Adventist Sabbath from Friday sundown to Saturday sundown, and I make sure all work is completed and nothing urgent is left pending before then.
