Project details
Running an Amazon store solo isn't sustainable.
Orders pile up. Customer messages stack. A–Z claims sit too long. Inventory drifts. PPC overspends. And somehow, the strategic work that actually grows the business never gets touched — because you're stuck in admin.
I'm an experienced Amazon Seller Central operator. I take over the day-to-day so you can stop being the bottleneck.
What I handle, every day:
✓ Order processing, tracking, and dispute resolution
✓ Customer messages, returns, refunds — under 2-hour SLA
✓ Inventory monitoring, restock alerts, FBA shipment plans
✓ A–Z claim handling, account health, performance metrics
✓ Listing updates — titles, bullets, images, A+ Content
✓ PPC monitoring with budget pacing and spend alerts
✓ Weekly performance reports and monthly P&L recaps
I work with FBA, FBM, hybrid sellers, and brand registered accounts. I use Helium 10, Jungle Scout, Merchant Words, and Viral Launch when research is needed.
One flat fee. No percentage of revenue. Full transparency on every action. You see what changed, why it changed, and what's next.
If your store is running you instead of the other way around, this fixes it.

Mumraiz did an excellent job on the test task. He completed it quickly, followed the requirements carefully, and delivered the work exactly as expected. He was also responsive and available whenever I had a question. I was very satisfied with both the quality of his work and his professionalism. I would definitely consider hiring him again for future projects.

I am really impressed with Mumraiz. He has excellent Amazon knowledge, fluent English, and a very professional approach. I also have 8 years of experience with Amazon, but his overall Amazon management and strategic thinking really stood out to me.
He has strong expertise in PPC, ACOS, SEO, catalog management, FBA, and Amazon policy issues. If you are looking for someone who understands Amazon A to Z and focuses on real results, I highly recommend Mumraiz.

Mumraiz was great at the beginning, but then fell behind and was not completing even the simplest of tasks. He is a great communicator, but I believe he already has a lot of clients he works for, and he has a hard time balancing all of the work.

Steps for completing your project
After purchasing the project, send requirements so Mumraiz can start the project.
Delivery time starts when Mumraiz receives requirements from you.
Mumraiz works on your project following the steps below.
Revisions may occur after the delivery date.
Onboarding & Account Audit
I get access to your Seller Central, audit the full account, flag anything urgent, and put together a baseline report. You see exactly where things stand before I touch a single setting. Usually completed in the first 24 hours.
Daily Operations Begin
From day one, I take over the daily rhythm — orders, customer messages, A–Z claims, and account health. Routine work moves off your plate immediately. Anything I'm unsure about, I flag and ask before acting on your behalf.
