The proposal does not fully reflect my expectations.
'Pienamente' = pye-na-MEN-teh. Four syllables; stress the third.
Use this when an offer comes in lower than your target but you do not want to reject it outright. It opens the door to a counter-offer without creating conflict.
'Non riflette pienamente' (does not fully reflect) is diplomatically chosen — it acknowledges the offer is partially acceptable while signalling that improvement is needed. 'Pienamente' (fully) is the key softening adverb.
L'offerta è leggermente al di sotto delle mie aspettative.
The offer is slightly below my expectations.
'Leggermente' (slightly) minimises the gap, making negotiation feel manageable

I was hoping to reach something closer to...
Uses imperfect to make it sound less demanding; very Italian in style
C'è margine per migliorare la proposta?
Is there room to improve the proposal?
