Hi Mastodon! #introduction
I'm Shub. I build free, no-sign-up tools for small online sellers and solo founders:
- EU €3 duty + €2 handling fee checker
- chargeback reply builder
- US LLC filing checker for non-US founders (Form 5472)
- property tax appeal checker
I'll post plain-English summaries of rule changes that cost small sellers money, and I'm happy to answer questions.
