Ask HN: How to land the first ERP client?

You need the first client to build an erp software and then replicate that across other clients in the same niche or industry. the question is, how can you achieve this without first spending lot of time building the tool and getting paid to solve their enterprise problem?

Here's how I envision creating a custom ERP tool.

1) Find a business with ERP needs. 2) Propose a solution. 3) Get paid 4) Deliver 5) Productize 6) Sell to other similar businesses 7) Hire 8) Grow

I'm also curious to know in what industries are real-time collaborative feature are a major selling point.
