Approaching sales-tax nexus in Texas — 84% of threshold. We're on it.

The problem

Four vendors. Four invoices. Nobody owns the full picture.

Your dev agency doesn't read your P&L. Your bookkeeper doesn't know a payout from a payment. Your sales-tax service never talks to your tax preparer. Data lives in silos — and you're the one stitching it together.

Dev agency

Ships features, never looks at margins.

Bookkeeper

Closes late; payouts don't reconcile.

Sales-tax service

Files returns, misses new nexus.

Tax preparer

Shows up in April, surprised by everything.

Asked by every seller we talk to

Nexus means a US state can require you to collect and remit sales tax there — usually once you pass ~$100,000 in sales or 200 transactions in that state. We track your sales by state daily from Shopify data, flag you at 80% of any threshold, and handle registration and filings when you cross it.
