# Making Pharmacies Smarter in Jumpseller: Custom Fields & Bioequivalents  

In Chile, pharmacies are legally required to **show the cheapest bioequivalent medications first** in search results. Makes sense, right? Why push people to pay more when there’s a perfectly good alternative?  

Now, **Jumpseller doesn’t do this by default**—but we can fix that using **Custom Fields**. The problem? Well... our custom fields setup is a bit like talking to a robot. Ever seen code like `field[0]`? Yeah, super intuitive. Thanks, past developers.  

But don’t worry—I’ll guide you through **how to add bioequivalents** and **make sure they show up first** in search results, while still keeping Jumpseller’s original search logic intact.
