Yeah, I've been there. My old boss used to say 'build trust, not bills,' but then quota day hits. I found that being upfront about optional add-ons actually builds repeat business. Like, instead of pushing a warranty, explain what it covers and let them choose. It feels slower, but your clients come back because they know you're not just after their wallet.
Honestly, my sales numbers look like a rollercoaster some months because I just can't bring myself to lie about a needed part. Tbh, I've watched guys who upsell every little thing make a quick buck, but then their phone stops ringing. Ngl, it feels good when a customer calls back and asks for you by name because you didn't try to scare them into a full repipe for a simple fix. The short term pressure is real, but so is the long term peace of mind from not hating yourself in the mirror.
