Great point. Let me rephrase this slightly to make it obvious that there is no contradiction between these two seemingly opposite pieces of advice. Do reinvent the wheel to solve your problems that you are then planning to sell to others. Do not reinvent the wheel to solve your problems that you are not planning to productize and for which you can easily get SaaS solutions. In other words, either create SaaS products, or use SaaS products. Don’t create one-off internal products that are not SaaS-able.
