That makes sense. If I were in your position, I would want to be sure specific concern is handled before moving forward.
For add-on recommendation, the practical way to look at it is this: specific detail.
If the goal is customer goal, the next step I recommend is next step. If that does not fit, I can suggest the simpler option instead.
Proof to add
Add one proof point only: a short example, a client result, a screenshot, a guarantee, or a clear limit. Too much proof can feel like pressure.
Sales note
Do not push past the concern. Confirm the risk, answer it plainly, then give the buyer a low-pressure next step.
