I am a senior developer with C# knowledge, and i have developed many console applications and web applications which integrate with external systems using APIs. now i run my small business and i have these 2 systems:-
1- Quickbooks POS desktop application.
and i want to integrate/sync these 2 platforms/systems. so when i sell something on the Quickbooks POS, to let the Shopify know about this. so i will not face an issue that i am shwoing an item on the Shopify which have been sold in the store(using the Quickbook POS). Now when i google this, i will get a list of paid tools which achieve this. but for me i am not sure if integrating both system is something that can be developed from scratch, by writing a console application which runs on schedule basis and update the Shopify with the Quickbooks actions?
