CereTax is the next-generation sales tax platform built to handle the complexity of scaling an ecommerce business.
If your BigCommerce store is growing fast, your sales tax system shouldn’t just keep up. It should support your scale. Most plug-and-play tax tools weren’t built for what comes next: multi-channel growth, bundled SKUs, increasingly complex shipping rules, and real audit risk.
At first, managing a few manual workarounds might feel easier than switching systems. But what starts as a “quick fix” becomes a daily problem that eats up your team’s time and exposes your business to compliance risk.
Plug-and-Play Was Fine… Until It Wasn’t
We’ve seen the same scenario play out over and over. Teams try to stretch basic tax tools by patching them with spreadsheets, disconnected platforms, and last-minute overrides. It works, until it doesn’t.
Over time, the tax technology stack becomes fragile, error-prone, and expensive to maintain. Businesses come to CereTax after realizing they’ve outgrown their current solution, not just because the software is limited, but because everything around it is too.
They’re dealing with inconsistent support, confusing pricing structures, and zero guidance when things get complicated. The lack of customization becomes a real obstacle to running their business. Support teams don’t understand their product or setup. They’re doing all the heavy lifting and still worrying about staying compliant.
CereTax Was Built for This Stage of Growth
CereTax is a certified sales tax partner on the BigCommerce platform, but we’re not just another app in the directory. We’re purpose-built for mid-sized ecommerce and retail brands that manage the complexity that off-the-shelf tax tools simply weren’t designed to handle.
Our platform is customizable by design. Whether you sell direct-to-consumer, B2B, or both, CereTax adapts to your product catalog, shipping methods, and exemption logic without constant manual updates. And the best part? You always have real people helping you work through what scale looks like for your business.
CereTax doesn’t just integrate with BigCommerce. It also connects seamlessly with your ERP, billing system, accounting tools, and other business technologies. You get clean, accurate tax calculations in real time, plus visibility into the product-level logic, legal citations, and sourcing rules behind every transaction.
Switching Doesn’t Have to Be a Headache
Let’s talk about the elephant in the room: migration. Switching to a new tax system sounds painful, but with CereTax, it will feel like coming home.
Our implementation process is fast, structured, and fully supported by a team that understands ecommerce sales tax inside and out. We walk you through each step, from configuration to testing to go-live, and tailor it to your business's unique needs.
That includes configuring rules for product-specific taxability, handling origin vs. destination sourcing, and syncing everything with your existing fulfillment logic. This isn’t a self-service install with vague help articles. It’s a guided, expert-supported transition designed to minimize downtime and eliminate confusion.
