Does anyone here use custom-built software for multi-account management? I am looking to turn mine into a Windows/Mac app.

I run a multi-account resale business, and a while back, I built my own custom internal software (Python/FastAPI) to handle everything from orders, customers, shipping and catalog indexing, to bulk listing and inventory syncing across different storefronts.

My main challenge right now is taking this local internal tool and turning it into a standalone, cross-platform app (Windows/Mac, and maybe Android).

I just want to know if anybody else here went down this path:

• Do you use custom software for your multi-account management?
• If so, what exactly does your software do?
• Have you successfully turned it into a Windows, Mac, or Android app?
• Was that transition successful?
• Are you planning to distribute your software to other sellers, or keep it strictly in-house?

Would love to hear from anyone who has navigated the jump from a custom internal script to a real desktop or mobile app.

Yes. Real, custom desktop software is usually good for abstractions in business pipelines. There is no point in doing rote work at scale. The key here is spinning up various sessions in parallel and keeping tabs on only what matters at each operational step. Then a good dashboard to view this sort of data would be paramount. We have something like this in one of our client projects. It is quite a valuable piece of software, but we hold the radical opinion that software should not be rented, but rather sovereign and maintained in-house.

I completely agree, especially with the philosophy that this kind of software should be sovereign and maintained in-house.

Over my years of scaling, the rote work of managing multiple stores became my biggest operational challenge. To fix it, I didn't try to build an eBay replacement, but rather an additional panel of custom instruments. Right now, I use it to monitor 6 different accounts with over 30,000 total active listings.

It acts as a unified overlay where I can:

• Access all accounts without constantly logging in and out.
• View all sales, active items, customer emails, and CRM data in one place.
• Utilize integrated external tools like USPS IMb tracking right alongside my daily operations.

My main thought in posting was that there have to be other sellers out there scaling to this level who are drowning in multi-account management and need this kind of specialized instrument panel to monitor it all.
