I am in the same boat as you.  I started using Desktop POS in 2005.

I am mainly a brick and mortar store with over 8000 item numbers at this point since i just kept creating new ones.

I dont know what i am going to do.  This whole switch to shopify doesnt sound practical

to make matters worse, I also use the enterprise software and intuit cc processing and hardware. It like Im going to have to spend thousands of dollars and now is not the best time for that.

Just think.  We have survived 2008 collapse and then COVID, but going to be taken down by my own software company.
