Whether you are bootstrapped, just getting started, or established, the decision to decide whether to try to build a feature/function yourself, or integrating something existing can be quite difficult. There are opportunity costs for either direction you take. It’s good to grow your product quickly, but you’re still limited by the resources provided to you.  No doubt, there are great tools out there you can use to quickly enhance your product.  But are they good enough for what you want to accomplish, and will it fit in with exactly what you need?  Here are a few pros and cons I suggest to consider:

Build It	Buy It
Slow to deploy	Quick to deploy
Flexibility of features	Limitations of features
Unproven functionality	Proven functionality
More developer hours	Less developer hours
Flexibility of design	Limited design
Opportunity cost	Possible high dollar cost
Ability to iterate	Limited ability to iterate
Ease of a MVP	Challenging MVP. Sometimes all or nothing
Downtime at helm of developers	Downtime at helm of vendor
Ability to enhance features easily	Feature enhancements limited by vendor’s development pace
Agile	Waterfall
