Head to head, with the two Isan leaders for scale
| Province | Companies | Revenue, billion baht | Revenue per company, million baht |
|---|---|---|---|

Registered companies, reported revenue and revenue per company, as of 17 Jul 2026.
Why the two rankings split
A company count measures how many doors are registered. Revenue measures how much money flows through them. Udon Thani has the longer list, but its average firm is smaller. Ubon Ratchathani has a shorter list, and its average firm books 37.5 percent more revenue than Udon's. The pattern looks like Nakhon Ratchasima in miniature. Ubon's 15.34 million baht per company sits close to the Isan leader's 15.74 million. Udon's 11.16 million sits below Khon Kaen's 13.29 million. Neither number says one city is the better place to do business. It says a sales team counting prospects and a lender counting turnover would draw different maps of the same region. Provincial output is also tracked separately by the national planning agency, so readers who need gross provincial product should consult that series (NESDC, 2026).
Why this matters
Count-based targeting will send you to Udon Thani first. Revenue-based targeting will send you to Ubon Ratchathani first. A supplier chasing volume of small accounts has a larger pool in Udon. A supplier chasing fewer, heavier accounts finds richer ground in Ubon. Both cities are still small beside the leader, since Nakhon Ratchasima alone holds 33,958 companies. Treat the pair as two different kinds of regional market, not as one ranking with a winner.
Definitions
- Registered company
- A juristic person on the DBD register in the province of its registered address, whether or not it still trades.
- Reported revenue
- Total revenue summed from the financial statements that companies filed with the DBD.
- Revenue per company
- Province revenue divided by all registered companies in the province. It is an indicator of average scale.
- Isan
- The northeastern region of Thailand.
Assumptions
- Revenue covers only companies that filed a statement, so true provincial turnover is higher.
- Companies are assigned to the province of their registered address, which may differ from where they operate.
- Revenue per company divides by all registered companies, including dormant ones, so it understates the average for active firms.
- A single very large company can move a provincial revenue total, so the gap is not proof of broad strength.
Methodology
Company counts and revenue are provincial aggregates from the Department of Business Development registry, drawn from the Max Data aggregate tables computed on 17 July 2026 and described as of that date. Companies are counted by registered province. Revenue is the sum of revenue from filed financial statements, so provinces where fewer companies file will understate true turnover. Revenue per company is total province revenue divided by all registered companies in that province, not only filers, so it is an estimate of average scale and not a measured average. Figures are in baht and rounded to two decimals in billions.
