Why IC
Experts who know the field
We are a professional team with first-hand experience in Chiang Mai. We do more than the numbers — we truly understand how local businesses work, and we turn every complication into something correct.
Powered by technology
We move beyond traditional bookkeeping with online accounting software. You can check your business figures yourself without waiting for the month-end report, and our team always works from the same data as you.
Close, friendly care
We serve from the heart, with advice that is easy to understand and never complicated, and we are business advisors who come out to look after you on site.
Everything in one place
Save time and hassle with services that cover it all: accounting, tax, company registration, Visa/Work Permit and even Media Content production.
No paper needed
Send your documents online anywhere, any time. No more boxing them up and driving to our office every month, and no need to store old files, because everything can be found in the system instantly.
Systems we built ourselves
We wrote our own document storage and internal management systems instead of stitching together off-the-shelf products, so they always fit how we really work, and we can answer questions about job status or filing deadlines the moment you ask.
Behind The Scenes
From our accountants and review process to government filings and sharing knowledge with your business.
