I do not understand your question clearly, but as far as I understand you want to have a time difference other than 0 days. You would then have to use other dateparts (first argument to DateDiff()) See the MS documentation of DateDiff for details, or the DateAdd function.

Furthermore, maybe you want to use

i.date between DateAdd(dd, -10, getDate) and getDate()

(which would show everything between ten days ago and today).

declare @day integer

select @day = 10

Select * from client c 
inner join invoice i on c.id = i.ClientID 
WHERE 
DateDiff(dd, i.date, dateadd(dd,@day-datepart(dd,getdate()),getdate())) = 0
