Our Services

What we take care of for your business

Every service from IC Accounting & Service, an accounting firm in Chiang Mai — from monthly accounting and year-end financial statements to company registration, visas and work permits.

Why IC

Why choose IC Accounting & Service?

01

Professional Expertise

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.

02

Tech-Driven Accounting

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.

03

Personalized Service

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.

04

One Stop Solution

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.

05

Paperless Workflow

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.

06

Our Own Ecosystem

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

A real team, looking after every step

From our accountants and review process to government filings and sharing knowledge with your business.
