I wrote over 80 contracts. Here's what I learned.
Not by choice. By necessity.
I built a physical product brand from scratch. No legal background. No lawyer. No budget for one. Just a product, a factory in China, and a long list of vendors, agencies, engineers, scientists, and contractors I needed to work with.
Every agreement I signed taught me something. Most of those lessons were expensive.
Here is what I know now that I wish I knew then.
Vague language always gets interpreted by the other party. Not you.
I hired an influencer. 20 reels, different outfits, different locations. Clear enough right? They delivered 2 outfits and 2 locations. Technically fulfilled the contract because I never defined what different meant. That was on me.
Templates protect the person who wrote them. Not the person using them.
Every template I downloaded was written for a general situation. My situation was specific. Mold ownership. Tooling rights. IP clauses for physical products. None of it was in the template. I was on my own.
The words that sound professional can mean absolutely nothing.
I had a freight forwarder go quiet on me with $40,000 of my inventory sitting in China. For weeks he had been telling me the shipment was booked, in process, being handled. Meanwhile my product sat in his warehouse going nowhere.
I eventually got the tracking link.
The shipment hadn't left China until September 30th. It was supposed to leave September 9th. Trump had just raised tariffs by 135% on Chinese imports. I was racing to get my inventory out before the window closed. That window closed. Black Friday was gone too.
And I had a 20 page contract.
It still wasn't enough.
Booked does not mean confirmed. In process does not mean moving. Handled does not mean done. If the language is not defined in writing it will be interpreted in the most convenient way for the other party.
The clause that costs you is never the one you thought about.
It is always the one you didn't know to include. The delivery milestone clause. The required documentation at each stage. The penalty for delays. The definition of what booked actually means in writing.
Most founders don't lose because they had no contract. They lose because the contract didn't cover what they assumed it did.
After 80+ contracts and enough expensive lessons I built the tool I needed back then.
