THIS BID / offre / devis is valid till (This needs to be sepcific)

[les-les]

In times of volatile prices and other unfunny things it MUST be specific how long a
bid / offre / devis is valid.

As far as I see the one 1 month valid is somewhere stored,
as a quick and dirty solution, change the 1 Month to 29 days.
and ad a Second line: (so when the bid was created on the 1st of march)
it looks something like that.

This bid is valid for 29 days starts with : 01.03.2023
This bid is valid till 30.03.2023 11:00 am CET

This gives you absolute transparency for how long your bid is valid and a much more important stronger legal standpoint.

When you are able to set any duration fro 0 days to 90 days (and lets be fair a quote valid for 90 days wow ...)
you can simple calculate and track if the bid is still valid or near expire date. and as a bonus you can monitor this in your own bid tracking dashboard in gestion ... but Thats a BONUS
