Hi,
Apologies for bidding on higher side, but it's not really anywhere worth of 250 AUD.
Here is idea, how this integration will work. I had a looked into both system's API and it can be done.
What we need is middleware, where we can write the code and sync both the system, a server, if you do not have any server at the moment, I can develop this into Windows exe and it will be installed in your machine.
Once your machine is UP, it will sync the data every 1 hour or on button click ( if you sometimes want to initiate on immediate basis.) assuming that, your machine will have internet connection.
Also, you need to decide a Master system, I guess it will be Insightly CRM, having said master system is, Data will flow only from one way, i.e Insightly CRM to Workflow Max, not the other way around.
Looking forward for mutually beneficial partnership ahead.
P.S this cannot be done Zapier, as Zapier currently do not support Wrofklow max.
Thanks,
