Shabbos Maariv

Question

I was out of town last week, where I had no minyan to daven. I was wondering if what I did was correct. I first davened Mincha and Kabbalas Shabbos, then started my seudah (as the real zman for maariv had not yet begun) and then sometime after the zman, but d\before I bentched, I davened Maariv. Thank you in advance
