Sales tax made simplier.
Global sales tax platform powered by AI and tax experts.
If notice management has burned you before, this blog post is for you. Let me tell you how we handle notices, because it's genuinely different from most providers.
Here's the secret. Almost no sales tax notice starts as a letter. It starts as a line on a state portal. A balance flagged on a period you already filed. A frequency that quietly changed. A license renewal creeping toward a deadline. The letter is the last step, not the first, and by the time it lands in your mailbox you've already burned two or three weeks off a response window nobody told you was running.
That gap is where the risk lives. And it's exactly where most providers built their whole strategy. They wait for the state to mail something, catch it in a virtual mailbox, and react. Works great until it doesn't.
Reactive means you're always a step behind.
The state posts something. Eventually mails it. The mail gets scanned into a mailbox. Somebody reviews the scan, someone else routes it, and then, finally, someone has to deal with it. Every one of those handoffs burns days you don't get back, and the clock on your response window has been running the whole time.
Recently, we handled a clear example of this. A state issued a filing frequency change effective July 1, 2025, but the notice announcing it wasn't created until August 11, six weeks after the change was already live. And that's just when the notice was generated. The mailed copy went out well after that, so a mailbox-based provider wouldn't have seen a thing until it finally arrived and got scanned, months behind the effective date. By then you're not getting ahead of a frequency change, you're apologizing for a missed filing.
Notices get worked on the mailbox's schedule instead of the state's, and the ones that matter most aren't necessarily the ones that surface first. You're reacting to whatever showed up, not to what's actually urgent.
And a mailbox only catches what the state bothered to mail, whenever it got around to it. Some states don't mail reliably. Some post online and never mail at all. Some mail to an address you changed three years ago. A mailbox is only as useful as what lands in it.
Why a virtual mailbox doesn’t solve the problem.
A virtual mailbox is a sorting tool doing a coverage tool's job, and it's not qualified for it. It tells you what showed up and nothing about what didn't.
There's always a gap between where the state sends mail and where the mailbox catches it, and you'll never know what you missed, because a mailbox can't tell you about mail that was never sent.
And here's the thing that really gets me. You end up doing the sorting. A mailbox catches everything, not just sales tax. Income tax, franchise tax, licensing, unemployment, all of it. Same big pile. A sales-tax-only provider either digs through the whole mess or hands it back to you. Either way, correspondence for a tax nobody's watching can sit there unopened until it's a problem.
What we do instead, we go get them.
We don't wait for the state to come to us. Where we have portal access, we go in and grab it ourselves. Renewals, frequency changes, adjustments. Straight from the source, on the state's clock, not the post office's. We monitor portals across all 45 sales-tax states plus DC, so we're not waiting to find out.
Because we're in the portal, we see a notice when it posts, not weeks later, if it mails at all. We catch things that were never going to hit a mailbox. And since we only want the notices tied to filings we run, we take what's ours and leave the rest right where you and your other providers can find it. Business tax provider on the account? Their notices stay put, untouched. We're not dumping everything in one pile and handing you a shovel.
We've resolved more than 75,000 notices this way, most of them before they ever reached a customer's mailbox. Most of the time you'll never even know a notice existed. We anticipate it, work it, done.
Software finds it, people fix it.
Scraping gets us there, but scraping isn't resolution. A balance still has to get diagnosed. A frequency change still has to get worked into the calendar. An adjustment still needs someone who knows why the state adjusted it and whether they're even right.
The software does the finding. Our team does the part that needs a brain, and we're the best you'll find anywhere. These aren't people reading off a script, they are problem solvers by nature. They know why a state adjusted a return before they open the notice. They know which frequency changes are routine and which are the state trying to tell you something. They know when a balance is real, when the state fumbled it, and how to push back when it did.
That combo, technology that finds everything and a team that actually knows what to do with it, is what nobody else is putting together. Most providers have one or the other. We built both, on purpose, because notices don't get resolved by catching them. They get resolved by anticipating the issues through years of experience and knowing what to do next. A mailbox tells you what showed up. We tell you what it means, then we handle it.
