$20 here, $10 there, eventually ends up as $600 monthly or more, and no customer anywhere in sight. That may, or may not be sustainable or make sense.
Flush with cash? Knock yourself out. Bootstrapping? You can spend that money a lot more effectively than just loading up on a bunch of overpriced SaaS products to make life easier. You have to earn the easy route by growing your revenue.
If you are an actual early stage venture I don't believe those costs meet a high enough threshold to matter.
