It whould be great to combine trello (www.trello.com - for me the perfect project management tool) and primaERP so it could be used in one surface. I NEED trello for my work and I also love, how to track the time with primaERP I spent in projects. But unfortunately it is just too inefficient to bring both permanentely up to date. In this case I'm trading time for money.
Maybe it whould be possible and in your interests, to find a efficent solution for this? :)
If primaERP decides to implement https://primaerp.uservoice.com/forums/223680-time-tracking/suggestions/7174828-zapier-integration, you will be able to not only integrate primaERP with Trello, but with A LOT of other web services...
