Jared Stark founded Incendico Fire Alarm Store ten years ago, buying and selling surplus new and used commercial fire alarm equipment online.
For years, eBay handled sales tax automatically. In 2025, Jared expanded to Stripe for direct invoicing and added a Shopify storefront. That expansion made the tax complexity eBay had been absorbing visible overnight.
Multi-channel expansion
Incendico serves everyone from individual buyers to multinational companies. Many buyers are tax exempt, which meant tracking exemption certificates and state-specific documentation manually.
Jared had briefly used Stripe Tax, but it did not monitor exposure in real time, register Incendico in new states, or handle filings.
“Once you start branching off into additional channels, you suddenly realize how complicated it is to make sure you're abiding by the tax rules in every jurisdiction you're selling in.”
Quick to set up
Jared connected Shopify, Stripe, and QuickBooks using Kintsugi’s prebuilt integrations. Within a few hours, he had a clear picture of his tax exposure.
“It was incredibly easy. Kintsugi already integrates with the apps I use, so it was as simple as clicking the setup link, signing into my accounts, and all the data synced over automatically.”
Compliance in the background
Kintsugi monitors Incendico’s transactions across 19 states and 2 countries, tracks progress toward nexus thresholds, and handles registrations and filings as they come due. Jared checks in occasionally while the platform runs in the background.
When Incendico acquired a larger customer in Canada, Kintsugi’s support team helped explain Canadian requirements and handled registration on Jared’s behalf.
“Kintsugi provides me with the value of taking care of an essential regulatory process of running my business.”
