Surviving Azure Marketplace Co-Sell as a Solo ISV
Microsoft's docs tell you how to publish. They don't tell you which parts of the process are quietly wrong, stale, or waiting to fail — often after you've already submitted. This guide is a record of specific, real failures hit getting real products through Partner Center, co-sell, and marketplace-review directories, with the actual fix for each one.
What's inside:
- Why a role GUID can pass every automated check and still fail a customer's deployment — and the one command that actually verifies it
- How a secret can get silently baked into your offer package and pull your live listing offline
- The real Partner Center limits (keyword slots, character counts, category taxonomy) that differ from what docs and evaluation reports say
- Why "Review failed" on co-sell status often isn't a problem at all — and the one policy number to check before you go chasing it
- A stale dropdown value that blocks co-sell document uploads, and the exact fix
- The G2/Capterra/GetApp/Software Advice listing-completeness checklist that goes well beyond "write a description"
- A pre-submission checklist to run before every Partner Center upload
The Real Math of Reselling on Poshmark, Mercari & eBay
Most reselling advice is a platform's cheerful FAQ or a creator's vibes about what sells. This guide is the actual arithmetic — built from running real inventory across all three platforms — showing exactly what a sale nets after fees, where shipping quietly eats your margin, and how to price against real data instead of guesses.
What's inside:
- The exact fee math for Poshmark, Mercari, and eBay, with worked dollar examples
- The single most common eBay pricing mistake — and the ~$6 per sale it silently costs when missed
- Where to actually buy shipping labels, and the dimensional-weight trap that inflates cost on bulky-but-light items
- Why a "40-60% of retail" pricing rule can be badly wrong, and what to check instead before you trust it
- A markdown cadence that actually gets applied instead of just logged and forgotten
- How to spot the highest-leverage items in your own closet using engagement signals you're probably ignoring
- A five-step pricing worksheet to run through before listing anything
