MarginFlow reads your signed contract and your Gmail (read-only) to catch client requests that are quietly outside scope — the "can you just also..." emails that eat your margins. It flags them, then drafts a change-order email you can send in one click. Built this after losing count of the hours I gave away for free on client work.

Hey Product Hunt 👋 I'm a solo dev/founder, and I built MarginFlow because I kept doing the same thing on every client project: agreeing to "one small addition," then another, then realizing three weeks later I'd built half a new feature for free. The idea is simple — connect your Gmail (read-only) and upload your signed contract, and MarginFlow watches for client requests that fall outside what you agreed to. When it spots one, it flags it and drafts a change-order email for you, so you're not the one who has to be "that person" asking for more money. It's live now at marginflow.in if you want to try it. Would genuinely love feedback from anyone who's ever eaten a scope-creep hit — what would make this actually useful for your workflow?

I used to just eat it. A client would say "can you also just add this small thing" and I'd say yes because pushing back felt awkward, especially mid project. Add that up over a year and it's real money left on the table. Not a huge invoice you'd notice missing, just a slow leak that quietly eats your margin.

I ended up building something for myself to fix this called MarginFlow. It reads your signed contract and connects to Gmail so it can catch client requests that fall outside scope, then drafts a change order email so you're not the one who has to bring up money. Launching it on Product Hunt soon.

Curious how others here handle this. Do you have a formal process for flagging scope creep before it eats your profit, or is it mostly a gut feeling and hoping the client doesn't push too far? Would love to hear how people actually protect their margin on client work.
