Experts in Global Receipt Scanning Software

TAGGUN is a specialist API for receipts and invoices. Businesses trust it to extract their data with high accuracy, validate campaign entries and detect fraud. Our mission is to help you automate processes, protect budgets and improve customer experiences.

Our Story

Founder CK Lee started work on TAGGUN in 2016. He wanted to turn the text on a receipt into reliable, structured data.

He built TAGGUN as a specialist engine that handles receipts and invoices and nothing else. That focus on their unique challenges gives it world-class data extraction.

Fraud Defence and Proof of Purchase

As we grew, our clients brought us a new problem, especially those running consumer promotions and loyalty programmes. Receipt fraud was rising fast and getting more sophisticated. Proof of purchase was also hard to check, because each entry had to show the right products, stores and dates on receipts from thousands of different retailers.

So we built on our extraction engine. We added the fraud defence and automated validation logic needed to solve both problems at scale.

How We Work

We combine deep technical skill with a focus on client success. We take on complex problems, and we’re ready to adapt as your real-world needs change.
