Thank you Cédric and Sergi.
I am a tryton’s user since 2013 for my company. My customers wants to change their old proprietary erp.
The functionality that i am seeking is close to what you have presented. My customer have some itinerants technicians. And they want to invoice quickly through the signature of the technical intervention on final customer site.
There are previsionals interventions for maintenance, the technician the morning get his planning and take the road for inspect installation. At the end, the final customer signs the technical intervention. The next deadline intervention will be calculated according to some rule (periodicity, day of intervention, etc.) It is possible while the intervention, invoice somes unexpected articles.
It’s not exhaustive.
Thank you for all.
