The situation
Jessica’s Shopify store grew fast during 2022. She collected Colorado sales tax, but she had passed the economic nexus thresholds in 29 other states without knowing it, and her inventory never matched her books.

What we did
First we measured the problem, then fixed it state by state.
- Ran a nexus study to find every state where she owed and how much.
- Registered in each state and filed voluntary disclosure where it limited back tax and penalties.
- Connected Shopify, Amazon and her payment processors to the books with automated sales tax filing.
- Started monthly inventory reconciliation and cost of goods tracking by product line.
The results
North & Pine now files in 30 states without anyone touching a spreadsheet. Voluntary disclosure kept back taxes to a manageable amount with no penalties, and Jessica gets about 11 hours a month back.
“I was scared to even look at sales tax. Quantro found every state, fixed the past and set it up so I never think about it.”
