Digital Economy vs Professional Services in Thailand 2026
In short
Professional and technical services post a 13.6 percent net margin as of 7 July 2026, more than double the 5.8 percent margin in information and communication. Flip the lens to scale and the ranking reverses. Information and communication generates about 25.4 million baht in revenue per company, roughly 3.25 times the 7.8 million baht that professional services earns per company. Professional services also runs on nearly triple the headcount of firms, 138,962 against 52,537. Bigger companies, thinner margins. Smaller companies, fatter ones.
Which sector wins, margin or scale?
It depends which question you ask. On profitability, professional and technical services wins clearly, keeping 13.6 baht of every 100 baht it books as net profit against 5.8 baht for information and communication (DBD, 2026). On scale per firm, information and communication wins by an even wider margin. The average information and communication company reports about 25.4 million baht in annual revenue, versus 7.8 million baht for the average professional services company, a gap of roughly 3.25 times. Professional services makes up for that with sheer numbers. It counts 138,962 registered companies against 52,537 for information and communication, a ratio of 2.65 to 1. Two very different businesses sit inside these labels. Information and communication covers telecom operators, internet providers and software firms, many of them capital heavy. Professional and technical services covers law firms, accounting practices, engineering consultancies and architecture studios, businesses that sell expertise rather than infrastructure.

Why this matters
The comparison cuts against the usual story that a digital economy is where the money is best kept. In Thailand's own registry, the opposite holds for margin. Professional and technical services turns more of every baht into profit and earns a better return on both equity and assets. Information and communication still wins the size argument, and by enough that its average company earns nearly 40 percent more net profit in absolute baht than the average professional services company, even while keeping less than half the share of each baht it takes in. That is the arithmetic of scale beating margin. There is a curious footnote in the data too. Information and communication's single largest revenue company is Advanced Wireless Network, the mobile network operator behind the AIS brand. Its listed parent, Advanced Info Service Public Company Limited, sits at the top of the professional and technical services table instead, a reminder that TSIC classification tracks a company's registered activity, not always the brand a customer sees. For a country betting policy attention on becoming a digital economy hub, the margin data is a useful check. Building networks and platforms is a volume business here. Selling expertise still pays better per baht.
Definitions
- Net margin
- Net profit as a share of revenue. A ten percent margin means ten satang of profit for every baht of revenue.
- Return on equity
- Net profit as a share of shareholder equity. It measures how much profit a company generates from the capital its owners put in.
- Return on assets
- Net profit as a share of total assets. It measures how efficiently a company turns everything it owns into profit.
- Revenue per company
- A sector's total revenue divided by its number of registered companies, an average that shows typical company scale, not typical profitability.
- TSIC section
- One of 21 lettered top level categories in the Thailand Standard Industrial Classification. Information and communication is section J. Professional, scientific and technical services is section M.
Assumptions
- Only companies that filed a financial statement contribute to revenue, profit and margin figures. Companies without a filing are excluded from both sectors equally.
- Sector margins are aggregate, total sector profit over total sector revenue, not the average of each company's individual margin, so large filers carry more weight.
- TSIC classification reflects each company's registered activity. A parent holding company and its operating subsidiary can sit in different sections, as seen with the top companies in this comparison.
- Revenue and profit per company are simple averages across all registered companies in a section, including small and dormant filers, so they understate the typical figure for an active mid sized firm.
Methodology
Net margin, return on equity and return on assets are aggregate sector figures, computed as total sector net profit or profit proxy divided by total sector revenue, equity or assets across all companies in each TSIC section that filed a financial statement, drawn from the DBD registry via the market_section_insight table as of 7 July 2026. Revenue and profit per company divide each section's total revenue or net profit by its registered company count. Information and communication is TSIC section J. Professional, scientific and technical services is TSIC section M. Figures are section wide aggregates, not the average of each individual company's own ratio, so a small number of very large filers can move the result.
How we verified this
