Vincero Collective designs engravable watches, jewelry, and eyewear meant to commemorate life's defining moments, backed by a lifetime guarantee and a customer base of over 500,000 worldwide. Selling primarily direct-to-consumer through Shopify, the multi-million dollar ecommerce brand has scaled into a genuine multi-state sales tax operation, filing across 39 states. But for years, that scale outpaced the tools Vincero used to manage it. Since switching to Kintsugi in May 2025, Vincero has gone from receiving 15-20 late filing notices a month to zero. With Kintsugi, they’ve experienced 100% accuracy and timeliness of filings for 16 straight months.
When Spreadsheets and Legacy Providers Don’t Work Out
Before Kintsugi, Vincero spent roughly four to five years with Avalara before moving sales tax compliance in-house with their accounting firm's sales tax arm, the same firm that handled their year-end accounting. It seemed like a natural consolidation on paper, but in practice, it meant no technology at all.
"They sent over a spreadsheet at the end of every month," said Aaron Hallerman, co-founder of Vincero. The agency pulled data from Shopify, calculated what was owed across roughly 40 states, and filed manually in each state's portal. There was no dashboard, no real-time visibility, and no easy way to confirm a filing had actually happened.
The gaps showed up in two costly ways. First, the agency wasn't fully aligned with Vincero on what was actually being collected versus what was owed, which led to under-collection in some states and a quiet loss of margin. Second, filings were consistently late. "We would get fifteen to twenty notices almost every month," Aaron said, describing state notices flagging missing or overdue filings. Reconstructing what happened meant digging through email threads instead of checking a live system.
Finding a Modern Alternative
Vincero's search for a new provider started close to home. Aaron asked other founders in his network before evaluating Kintsugi alongside Numeral and one other competitor.
"When you're doing a demo, it's hard to figure out if people are actually trustworthy," Aaron said. What tipped the decision was direct referrals to Kintsugi from other brands that were already customers, people who could speak specifically to accuracy, timely filing, and service quality, the things a sales demo alone can't prove. Kintsugi won on trust and experience, and Vincero ended up saving money on top of it.
Vincero's evaluation criteria were straightforward: a real dashboard was non-negotiable, timeliness and accuracy needed to be provable rather than promised, and the level of service had to hold up once they were a customer.
Onboarding and Registration
The Shopify integration was seamless, and the process of registering in new states was straightforward with Kintsugi handling all the legwork and avoiding any pitfalls. Kintsugi's dashboard flagged when the company was approaching or had crossed a new nexus threshold. From there, Aaron reviewed the alert, confirmed company information, and Kintsugi handled the rest. "It was extremely seamless," he said.
From 60% Accuracy to 100%
The clearest result is the disappearance of state notices. In 16 months with Kintsugi, Vincero has had zero missed or late filings. Any notices that still arrive trace back to periods before May 2025, and Kintsugi has taken on resolving that legacy back-tax cleanup as part of the relationship, even though it predates the partnership.
By Aaron's own estimate, the previous agency was filing accurately roughly 60% of the time in a given month. Kintsugi has been consistent at 100%.
The time savings compounded from there. At the start, Aaron manually reviewed and approved filings in Kintsugi each month, which was straight forward and still only took 10-15 minutes. And then after building confidence in the numbers, Vincero quickly moved to auto-approval, and Aaron now checks in only when Kintsugi flags something or roughly once a quarter to confirm totals.
