Bangkok and its surrounding provinces are served from our office on Soi Lat Phrao 95, Wang Thonglang.

Our own office here

Khon Kaen

Khon Kaen is the hub of Isan for trade, education, healthcare and logistics. Businesses here grow out of shopfronts, contracting, clinics, restaurants and service teams covering the whole region. The moment they start selling to companies, government agencies or the university, they are asked for a company certificate and tax invoices — which is when incorporation becomes the next step. This is also the province where we have a real office, so we can meet in person.

Udon Thani

Udon Thani is the trade gateway toward Laos and one of upper Isan's strongest consumer markets. Businesses here typically start in retail, building materials, tourism and services linked to Nong Khai and the border crossing. Once work crosses provinces or partners require tax invoices, incorporating widens the work you can take and makes bank financing easier.

Nakhon Ratchasima

Nakhon Ratchasima is Isan's largest province and a base for manufacturing, food processing and tourism. Many Korat businesses supply factories and industrial-estate partners, nearly all of whom buy only from registered companies and require tax invoices. Incorporation with clean books is an entry condition here, not an option.

See this province
Served from Khon Kaen

Ubon Ratchathani

Ubon Ratchathani anchors lower Isan and links trade toward Laos and Cambodia. Businesses range from wholesale and agriculture to contracting, education and healthcare services. Many start as sole traders and then find that bigger work requires a company — to bid, to open supplier credit, and to separate liability from personal assets.

Served from Khon Kaen

Maha Sarakham

Maha Sarakham is a university city with a large student and staff population. The fastest-growing businesses are dormitories, restaurants, print shops, student services and contracting tied to educational institutions. Invoicing government bodies or universities usually requires a registered company — the main reason owners here incorporate.

Roi Et

Roi Et is an agriculture and trade province within the Roi Kaen Sarn Sin group. Typical businesses are rice mills, grain trading, materials supply, local contracting and shops selling both in person and online. As they move from cash trade to credit terms and invoicing, being a registered company earns trust from partners and banks faster.

See this province
Served from Khon Kaen

Kalasin

Kalasin is an agricultural province driven by processing, materials trade and contracting. Most businesses are sole proprietorships taking on larger work and being asked for more documents. Incorporating with the right structure from the start avoids retroactive fixes to tax records and to the mixing of personal and business accounts.

See this province
Served from Khon Kaen

Nong Khai

Nong Khai is a border province anchored by the Thai–Lao Friendship Bridge, so cross-border trade and logistics are the core of business here. Operators in transport, import–export or product representation generally need a company to sign contracts, open credit lines and get tax treatment right from the start.

See this province
Served from Khon Kaen

Sakon Nakhon

Sakon Nakhon is known for community products, indigo-dyed textiles, organic farming and cultural tourism. Many operators start as community enterprises and grow into brands selling nationwide or exporting. Incorporating makes it possible to contract with distributors, obtain product certifications and enter retail channels.

See this province
Served from Khon Kaen

Buriram

In Buriram, sport and tourism visibly drive the city economy. Accommodation, restaurants, transport and event businesses grow with the race and festival calendar. Those working with event organisers or large partners must issue tax invoices and hold complete company documents — the main reason operators here incorporate.

See this province
Served from Khon Kaen

Surin

Surin's economy rests on jasmine rice, silk, handicrafts and border trade. Operators moving from provincial sales to Bangkok and overseas markets generally need a company to contract with buyers, obtain product standards and handle export paperwork correctly.

See this province
Served from Khon Kaen

Chaiyaphum

Chaiyaphum combines agriculture and energy — sugarcane, cassava, processing plants — with nature tourism around Phu Khiao and the Siam tulip fields. Businesses here usually begin as crop buyers, contractors or town shops. The moment they sell to a factory or a large partner, the buyer asks for a company certificate and tax invoices.

See this province
Served from Khon Kaen

Loei

Loei is a mountain-tourism and border province with a sharp season. Chiang Khan, Phu Ruea and Phu Kradueng drive accommodation, restaurants, cafés and tours in waves, while the Tha Li crossing supports trade with Laos. Businesses taking group bookings, contracting with booking platforms or seeking credit generally need a company and clean statements.

See this province
Served from Khon Kaen

Nong Bua Lamphu

Nong Bua Lamphu is a small province economically tied to Udon Thani and Khon Kaen — agriculture, building materials, contracting and town retail. Operators here often work across provincial lines, so the question of company paperwork usually comes from partners in the bigger cities first.

See this province
Served from Khon Kaen

Nakhon Phanom

Nakhon Phanom sits on the Mekong with the third Thai–Lao Friendship Bridge linking to Khammouane, making border trade, logistics and tourism its pillars. Businesses working with Lao partners or shipping through the crossing need company documents, tax invoices and statements a bank will accept.

See this province
Served from Khon Kaen

Mukdahan

Mukdahan is a major crossing to Savannakhet via the second Friendship Bridge and sits on the East–West Economic Corridor. Business here revolves around border trade, logistics, the Indochina market and tourism. Operators contracting with foreign partners need a company and auditable statements.

See this province
Served from Khon Kaen

Yasothon

Yasothon is a farming province known for organic rice and safe-agriculture produce, with community enterprises and processors selling into Bangkok and overseas. Product certification, buyer contracts and retail listings all require company documents, so stepping up from a group to a company is a common move here.

See this province
Served from Khon Kaen

Amnat Charoen

Amnat Charoen is a small province living on agriculture, retail and trade toward Laos through Chanuman district. Most businesses start as family operations; when they move into government work or sell to larger partners, incorporation and auditable books become necessary.

See this province
Served from Khon Kaen

Sisaket

Sisaket is a large farming province known for volcanic-soil durian, shallots and rice, with Cambodian border trade through Chong Sa-Ngam. Businesses moving from local sales to online markets, retail chains and export are usually asked for company documents and product certification first.

See this province
Served from Khon Kaen

Bueng Kan

Bueng Kan is Thailand's newest province, living on rubber, agriculture and Mekong trade opposite Bolikhamsai in Laos. Many operators here are small and moving toward contracts with rubber factories or Lao partners — which requires company documents and tax invoices to proceed.

Our own office here

Bangkok

Bangkok is where our own office sits — 61 Soi Lat Phrao 95 (Prangthip), Wang Thonglang — so it is the province where you can genuinely register at our address. Most Bangkok founders hit the same two walls: their condominium or home cannot be used as an office, and a real office lease costs far more than a young business needs. So we package the registered address, incorporation, monthly accounting and the website together.
