Growing your business should be exciting, not stressful. But as you expand into new states, channels, and markets, sales tax compliance can quickly become one more thing to manage.

It often starts with a simple question: How do I calculate the correct sales tax at checkout? Before long, that question grows into something much bigger. You may need to register in new jurisdictions, monitor changing tax obligations, and file returns on time. Keeping up with those requirements manually can quickly become another operational task competing for your attention.

That's why Kintsugi is now available in the SHOPLINE App Store.

The native integration gives SHOPLINE merchants a more complete way to manage sales tax compliance by combining accurate tax calculation at checkout with real-time nexus monitoring, registrations, and automated filings in a single platform.

Why Sales Tax Gets More Complicated as You Grow

As your business expands into new states or countries, you may establish what's known as sales tax nexus. Once you've crossed a state's threshold, you're generally required to register, begin collecting sales tax, and file returns according to that jurisdiction's requirements.

The challenge is that every jurisdiction has its own rules, thresholds, and registration processes and portals. Tracking those requirements manually becomes increasingly difficult as your business grows, making it easier to mess up a registration or miss filing deadlines.

For many merchants, sales tax isn't challenging because of the checkout calculation. It's everything that comes before and after.

More Than Sales Tax Calculation

Calculating the correct tax at checkout is only one piece of staying compliant.

Kintsugi helps merchants manage the broader compliance lifecycle through a single native integration. Instead of relying on multiple tools or manual processes, merchants can manage sales tax compliance from one platform as their business grows.

With Kintsugi, SHOPLINE merchants can:

  • Monitor nexus exposure in real time
  • Register in country, state, and local jurisdictions when required
  • Calculate accurate sales tax at checkout
  • Automate tax filings
  • Maintain audit-ready records

The result is a simpler, more complete approach to sales tax compliance that helps merchants spend less time on administrative work and more time growing their business.

“Kintsugi provides a ton of value to my business. After accidentally incorrectly registering for one state on my own, and then seeing that every state has a different system and requirements, I realized I could be making so many mistakes across the country with these things. After signing up with Kintsugi, they handle all the state setup and filings for me. I feel great knowing Kintsugi now is monitoring everything and they'll alert me when I need to take action.” - David Hewlett, CEO of SmartLabels

Built for Growing Businesses

Whether you're expanding into new states, adding sales channels, or entering new markets, compliance shouldn't become a barrier to growth.

Christopher Yang, Co-President of SHOPLINE, shared why Kintsugi was selected for the SHOPLINE ecosystem:

"We selected Kintsugi because our merchants need a more complete way to manage sales tax compliance as they scale. As merchants expand into new channels and markets, sales tax compliance can quickly become a drag on operations. Kintsugi helps them manage the full process, from monitoring nexus exposure and handling registrations to filing on schedule, so they can keep growing without adding unnecessary complexity."

In addition to its end-to-end compliance workflow, Kintsugi offers transparent per-registration and per-filing pricing, no implementation fees, 24/7 customer support, and an accuracy and performance guarantee.
