Why Shopify Sellers Choose Galvix for Sales Tax Automation
Most tax apps simply bolt onto Shopify and leave your team to manage the stressful state notices and monthly filings. We built Galvix for e-commerce operators who want a true managed compliance solution.
Developer-Free Set-up
We connect your Shopify store with you in a few one-time steps in your Shopify admin. We pull your transaction data and build your filing schedule, while Shopify remains your source of truth.
Time-Saving Automation
We track your nexus across all channels and manage the compliance work after Shopify checkout. For marketplace channels like Amazon, Galvix monitors transaction data for nexus tracking and compliance visibility rather than marketplace tax determination.
Real Tax Experts
Get direct access to a compliance team that understands your business, prepares your returns, and handles all state correspondence on your behalf.
Purpose-Built to Solve Sales Tax Challenges for Shopify
Works Alongside Shopify Tax
Shopify Tax can calculate sales tax at checkout and supports automated filing for eligible merchants. Galvix supports the compliance layer around it by reviewing Shopify data, monitoring nexus, managing registrations, preparing returns, and handling state notices.
Multi-Channel Nexus Tracking with Proactive Alerts
Shopify Tax only tracks sales on Shopify. If you also sell on Amazon, wholesale, or through other channels, you may have hidden tax exposure. Galvix monitors your sales across all active channels simultaneously, with alerts at 75%, 85%, and 95% of each state's threshold, so you have time to act before crossing a filing threshold.
Exemption Certificate Management
If you sell B2B, Shopify offers no native way to collect or store tax exemption certificates, leaving you exposed during an audit. Galvix offers exemption certificate management as an additional paid solution for businesses with advanced exemption compliance needs. The portal collects, validates, and tracks renewals for exempt buyers, helping your business stay audit-ready.
Our Sales Tax Experts Do It For You
Expert-Prepared Returns
We don't just hit "submit" on automated data. Our compliance team independently reconciles your Shopify data to catch discrepancies before filing any returns.
Done-For-You State Registrations
Crossed a nexus threshold in a new state? We handle the complex permit application and portal setup through modular pricing based on services used and work volume.
Audit and Notice Support
If a state sends a notice, we step in. Galvix compiles the audit trail and responds on your behalf, insulating your team from the stress of state deadlines.
