We've been using Integromat/Make for over 2 years and our now on a legacy plan. It has proven to have a quite the learning curve but if you have enough knowledge and possibly a dev person to assist, you can save a lot of money and headache utilizing it over Zapier. We avoided Zapier because the costs would have been prohibitive on our overhead but thanks to Make we were able to keep it much lower despite hiccups and headaches we did experience at times.
