I'm about 4 months out from leaving my corporate job to start a digital marketing agency and I keep getting stuck on the tooling side of things. Right now I'm looking at something like GoHighLevel for client management but I genuinely can't tell if that's overkill for someone with zero clients yet, or if setting it up properly now saves me from chaos later. My bigger problem is I don't want to sink $300-400/month into a software stack before I've closed a single deal, but I also don't want to look unserious when I'm trying to land those first clients. Anyone here who started solo, what did you actually use in month one versus what you added once money was coming in?
