Each state sets its own nexus thresholds and its own rules for SaaS. Rivet keeps track of both, so you collect the right tax everywhere you owe it.

Where Rivet comes in.

  • Nexus & taxability

    Where you owe and what's taxable, product by product, including how SaaS, bundles, and services are treated.

  • Registrations & VDAs

    New registrations, and voluntary disclosures for past periods where they beat filing back returns.

  • Right tax, every invoice

    Exact rates by address at checkout and on every invoice, in QuickBooks, Xero, NetSuite, or by API.

  • Filed & remitted

    Returns every period, reconciled to your books, with marketplace sales reported where states want them.

  • Exemption certificates

    Collected, checked, and matched to invoices, because a missing certificate makes the sale taxable on audit.

  • State mail & notices

    State mail comes to us. Every notice is triaged, answered, and closed, and you hear when it matters.

Four steps, then it's off your plate.

  1. Book a call

    30 minutes on what you sell, where you sell it, and how you bill.

  2. We map your exposure

    A nexus study across every state and city where you have sales, people, or inventory.

  3. We register and clean up

    Registrations where you owe now, and a plan for each period you missed.

  4. We file every period

    Returns filed and paid on schedule, with alerts before you cross the next threshold.

    Got a letter from the Washington Department of Revenue. Should I be worried?

  2. Luis VinkeRivet9:31 AM

    Not at all. You crossed Washington's $100K threshold in July, so we registered you and filed Q3, B&O tax included. That letter confirms your account. Next return is due January 31.

    Good to know. One less thing to worry about. Thanks.

Clients, in their own words.

  • Base Power Company
    “Most tax firms I came across were hyper disconnected from their clients. It felt like I was just another number to them. Rivet's been seamless. Especially with their updated dashboard - now, I can just go in and drop in the docs I have, and I'm all set.”
