MyPortFlow builds turnkey Shopify-based stores and lists them across eBay, Amazon, Walmart, Wayfair, Facebook Marketplace, Poshmark, Depop, Mercari, custom niche Shopify stores, and TikTok Shops — then manages every order under one dedicated office, for a single management fee.
“Most agencies sell access to a marketplace. We sell the discipline of running one properly — the pricing, the fulfillment, the tone of every reply to every customer.”
Every channel is opened, styled, and reconciled under the same house standard — no channel is treated as an afterthought.
Run the comparison before you list a single item.
A one-time build fee to open your store, a profit margin that's yours on every sale, and a small fee that keeps the office running.
Two points of your margin are set aside for 90 days, then released — sooner, if anything happens to your account.
If nothing disrupts your account for 90 days, the reserve built up in that window releases back to you automatically — in full, with the next cycle starting right after.
If your seller account is ever suspended or restricted, your full current reserve balance releases immediately — covering your exposure first, with anything left over refunded straight to you.
Your reserve balance, this week's contribution, and days to next release are shown in your weekly report — never buried in fine print.
A few of the reasons sellers move their business here.
No mystery, no waiting to find out where things stand.
We construct your storefront and catalog to the house standard, on your tier's turnaround.
Listings publish across every marketplace included in your membership, all together.
Your first sale sets the capital model below into motion — you're billed only after it's already sold.
Every marketplace holds your payout for a few days after a sale. We built the model so that delay never costs you anything.
Most sellers need working capital just to keep a shelf stocked — cash spent on inventory weeks before a marketplace ever releases a payout. There is none of that here. You never purchase inventory upfront, and nothing is billed until a customer has already bought the item.
The item sells on the marketplace, at the price your store has listed.
Only now are you billed — for that one item's wholesale cost, and nothing more.
By the time the marketplace releases your payout, the cost is already settled. What arrives is profit.
We review your category, capital, and channel preference, and confirm the right membership standing.
Your storefront, catalog, and identity are constructed to the house standard across each chosen channel.
Listings go live under your dedicated manager's supervision, typically within your tier's turnaround window.
Fulfillment, service, and reputation are held to standard on a running basis, reviewed with you on a set schedule.
