I am building a client onboarding portal for my small business and need to embed a PDF viewer API so people can fill out and sign intake forms directly in the browser. What features or pricing traps should I look out for before picking one, especially if most of my clients will be opening these on an iPhone?

Honestly, test how it handles mobile Safari first becuase iOS loves to break embedded PDF form fields. Also watch out for per-document or per-signature fees, they add up crazy fast. Look for flat monthly pricing and decent mobile zooming.
