You already have the hardest part nailed down - you actually get the restaurant world from the inside. Most people selling into that space are trying to fake their way through a conversation about ticket times and table turns. You don't have to pretend.
The real shift is learning to translate that insider knowledge into a value conversation that hits them where they live. Think of it like this: they're drowning in daily chaos, so you don't want to hand them a life jacket nobody asked for. You want to point to the exact leak that's sinking them.
Focus on the pain they feel every shift but don't have time to fix - missed reservations that cost them a full table, slow nights that eat into already thin margins, the soul-draining turnover of a worn-out team, no-shows that leave food prepped and nobody to serve it to. That's the language they speak.
Keep your pitch brutally simple. A restaurant owner is probably reading your message while one hand's on a POS terminal and the other's calming down a server who just got screamed at. Long paragraphs won't survive that environment. One clear sentence about a specific problem and how you solve it - that's your opening.
The trick is to sound like a colleague, not a vendor. No jargon, no buzzwords. Just "I've been there, I know how much wasted prep hurts, here's something that helped a place I used to work with."
And yes, expect to get shut down fast - especially during service. Rejection in this space is almost never personal, it's just bad timing and a thousand things on fire. The reps who win are the ones who come back calmly, again and again, without taking the brush-off as a final answer.
One thing that made a huge difference for me early on was running through possible objections before I ever picked up the phone. I'd sit down and just talk through different scenarios - how would I handle "we tried something like that before" or "I don't have time now" - so I wasn't trying to figure it out live while someone was knee-deep in a dinner rush. There are tools that let you do that kind of practice, but honestly, even just recording yourself and listening back helps.
You're already ahead of most people starting out because you speak the language. That's the hardest bridge to build. Just lean into it.
