Thailand Software Stack (2026)
The definitive software stack for Thai SMEs and ecommerce, covering LINE OA CRM, PromptPay integration, and e-Tax compliance.
For a Thai SME in 2026, the essential stack centers around **LINE OA**. Use **Kaojao** or **Zort** for social commerce and inventory management. For payments, a gateway like **Opn** (formerly Omise) or **Xendit** (which acquired Thai gateway GB Prime Pay) is required for seamless PromptPay QR checkout. Finally, connect your sales to **FlowAccount** or **Peak Account** for automated e-Tax invoice generation.
The Tools in Detail
Zort
E-commerce Operations · From THB 600/month · Thailand, SEA · TH / EN
Zort (ZORT) is a Bangkok-founded stock and order management system used by Thai online sellers to run online and offline stores from one dashboard. It connects to Shopee, Lazada, TikTok Shop, and LINE, syncs stock in real time, and integrates with Thai logistics providers including Kerry Express, Flash Express, J&T Express, Ninja Van, and Thailand Post, with pricing billed in Thai Baht.
Zort is built around the exact stack a Thai online seller uses day to day: Shopee, Lazada, TikTok Shop, and LINE for social commerce, plus direct label printing with Thailand's dominant couriers (Kerry Express, Flash Express, J&T Express, Ninja Van, Thailand Post). Pricing and invoicing are in Thai Baht and the interface is available in Thai, a depth of local integration that generic SEA-wide inventory tools do not match.
Best for: Thai online sellers running Shopee, Lazada, and TikTok Shop simultaneously; Social commerce sellers taking orders through LINE and needing centralized fulfillment; Thai SMEs replacing manual courier booking with direct Kerry/Flash/J&T label printing; Growing Thai retailers needing multi-branch and multi-warehouse stock visibility
Kaojao
E-commerce · From THB 1390/month · Thailand · TH
Kaojao is a Thai social-commerce assistant that automates the chat side of selling on Facebook, Instagram, and LINE Official Account: auto-replying to comments and inbox messages, pulling comments into the inbox so orders are not lost in threads, broadcasting to past customers, and printing delivery slips. Its Kaojao Live module handles CF live-selling — capturing comment orders from a Facebook Live, deducting stock automatically, and opening bills with payment-status tracking. A Sale Page builder ships landing pages with Facebook Pixel, TikTok Pixel, Google Tag Manager, and Google Analytics attached, and the platform can pull bank-transfer slips automatically for payment checking. The vendor states its bots reach more than 5,000,000 Facebook, Instagram, and LINE users per month.
Kaojao is built for the way Thai social sellers actually operate: closing sales inside Facebook comments and LINE chats rather than on a storefront, running CF live sales, and verifying payment from bank-transfer slips. Comment-to-inbox capture, automatic slip retrieval, and LINE OA selling are core features rather than integrations, and pricing is published in Thai Baht.
Best for: Thai Facebook and Instagram page sellers closing orders in comments and chat; CF live-selling merchants who need comment orders captured and stock deducted during a Facebook Live; Sellers running Facebook, Instagram, and LINE OA from one inbox without hiring more admins

SEA Operational Reasoning
Thailand is a mobile-first, social commerce-driven market where LINE is the primary operating system for business-to-consumer interaction. A standard Western CRM is ineffective; businesses need a LINE-native CRM or chat management tool like Kaojao or Zort to close sales directly in chat. Secondly, credit card penetration is low compared to the explosive adoption of PromptPay. Integrating a local payment gateway ensures you capture the majority of buyers. Lastly, the Thai Revenue Department's push for e-Tax invoices means manual accounting is obsolete—local platforms like FlowAccount and Peak are pre-certified to handle this natively.
Related Expert Guides
The questions operators actually ask.
Do I need a special CRM for Thailand?
Yes. Because Thai consumers prefer to chat before buying, a CRM must integrate deeply with LINE Official Account (LINE OA) and Facebook Messenger. Standard email-first CRMs like HubSpot require heavy customization to work well here.
What is the best way to accept PromptPay online?
While you can manually verify bank slips (slip checking), automating this via a payment gateway like Opn or Xendit reduces fraud and manual labor significantly.
Can I use Xero or QuickBooks in Thailand?
You can, but they do not natively support the Thai Revenue Department's e-Tax formats or local withholding tax complexities out-of-the-box. Local solutions like FlowAccount or Peak are much easier for Thai accountants to manage.
