Alienstacks Co., Ltd. is a Thai company registered in Bang Na, Bangkok (DBD Reg. No. 0395569000469) with a second operation in Tokyo. We work in Thai and English, and our point-of-sale software runs in more than 10,000 stores across Southeast Asia processing over $50M in annual transactions. For an SME in this region, the vendor being a real, visitable, locally registered entity is the risk that matters most.
If you run a retail chain in Bangkok, a restaurant group in Chiang Mai, a distribution business in Ho Chi Minh City, or a franchise network in Kuala Lumpur, you have probably already commissioned software once and been disappointed. The pattern is remarkably consistent across the region: a small development shop or a freelance team quotes a low fixed price, delivers something that demonstrates well on a laptop, and then the real conditions arrive — a hundred transactions an hour at a Saturday peak, a branch in a secondary city where the connection drops twice a day, an end-of-day reconciliation that is out by a few baht and nobody can explain why. Then the developer becomes hard to reach, and it turns out they still hold the hosting account.
The problem is not that regional development is cheap. It is that cheap delivery in this region usually comes without anyone senior owning the architecture, and the specific things that break here — offline behaviour, payment reconciliation, multi-branch data isolation, multi-language data — are architecture problems, not coding problems. They cannot be patched in later at low cost.
We are a different shape of company. We build and operate our own products, which means we live with our own architectural decisions in production instead of handing over a demo and moving on. Our deepest track record is directly regional: the point-of-sale platform our founding engineer architected now runs in over 10,000 stores across Southeast Asia — fashion retail, food and beverage, electronics, and pharmacy — processing more than $50M a year. On the AI side, our systems are in daily use at over 200 Japanese firms, and we operate in Germany, China, the United States, and Bangladesh.
And we are here. Bang Na, Bangkok. You can visit, meet the engineer who will design your system, and check our registration with the Department of Business Development before you sign anything.
For Thai clients there is no timezone to manage. For the wider region, the gap is at most two hours: Singapore, Kuala Lumpur, and Manila are one hour ahead of Bangkok, Jakarta is on the same clock, and Ho Chi Minh City and Hanoi are identical to ours. That changes how a project runs.
Kick-off workshops, store walk-throughs, and hardware testing happen face to face for Bangkok and greater-Thailand clients. We would rather stand behind your counter for an hour during a busy period than read a requirements document about it.
One senior engineer owns your system from the first meeting to production, in Thai or English. No rotating pool, no account manager relaying technical questions to people you never meet.
Even with same-day access, each working day ends with a written update — shipped, in review, blocked, and decisions waiting on you. Decisions get recorded so that in a year nobody has to guess why the system works the way it does.
Southeast Asian SME software has a distinct shape. Cash and QR coexist, staff turnover is high so interfaces must be learnable in a shift, connectivity outside the major cities is inconsistent, and most businesses operate across multiple branches or a franchise structure. What we are most often asked to build:
The relevant services are POS and payment systems — our strongest regional capability — Android app development (the dominant platform for staff-facing devices across the region), cross-platform app development for customer-facing apps that need both stores, iOS development where a native build is warranted, web application development for head-office portals, and AI development. See the full services list.
Three realistic options exist for an SME in this region, and being straight about the trade-offs is more useful to you than a sales pitch.
A regional office of a global consultancy or a Singapore- or Hong Kong-based firm brings process maturity, formal governance, and enterprise-grade documentation. If you are a large group with a board, an audit committee, and procurement requirements, that structure earns its keep.
Trade-off: cost several times higher for the same scope, and the engineering is frequently subcontracted to the same regional labour market anyway, with a layer of account management in between.
Locally registered, visitable, and working in Thai and English, with one senior architect owning your system — and the deepest regional production evidence we know of in retail software: POS in 10,000+ SEA stores, $50M+ a year in transactions, plus AI in daily use at 200+ firms.
Trade-off: we are a small senior team, not a body shop. We take a limited number of engagements, we will not staff twenty developers onto a project next month, and we sometimes tell prospective clients they do not need custom software at all.
Cheapest, fastest to start, and genuinely appropriate for well-defined low-risk work — a website, a landing page, a simple internal form, a prototype for an investor conversation. Plenty of capable independent developers work this way.
Trade-off: no senior architectural ownership, no continuity if the individual moves on, and — the recurring regional problem — often no separation between their accounts and your business assets.
We scope before we quote, because a figure without a scope is meaningless. The largest factors: whether money moves through the system, since payment integration, QR and e-wallet rails, refunds, and end-of-day reconciliation carry testing work that ordinary screens do not; whether it has to keep operating offline; how many branches, roles, and franchise levels must be modelled; how many languages and currencies are in scope; whether physical hardware — terminals, printers, scanners, cards — is involved and how many models must be certified; and whether we are building fresh or repairing an existing system, where discovery is unavoidable.
A single-branch mobile app with one staff role and no payments sits at the low end of our range and is measured in weeks. A multi-branch POS platform with hardware, QR and card payments, offline trading, and head-office reporting sits at the high end and is measured in months. We will tell you which end you are at in the first meeting, before you spend anything.
Three of our own products are live and open — no signup and no sales call required — and our case studies document the architecture, including the decisions we would make differently a second time.
Offline-first transaction journaling for stores in second- and third-tier cities, multi-tenant isolation across thousands of chains, and a hardware abstraction layer that lets new payment terminals be certified without rebuilding the app.
A mobile marketplace connecting Thai sellers with Bangladeshi buyers: multi-currency pricing, escrow, FX and fee deduction at settlement, and a language-aware listing schema. Live on both app stores in ten weeks.
An executive dashboard assembled from the files a business already produces — cash runway, branch and department profitability, and a scenario simulator, with every figure traceable to its source document.
Two more you can open right now: JP Accounting Suite, the AI workflow platform behind our Japanese accounting clients, and Virtual Office, a workspace where AI agents are hired like staff. For regional fintech and AI work, see PujiGori, a crowdfunding platform built on a local mobile-money rail, and our AI quoting pipeline, which took a Japanese manufacturer's six-hour quoting process down to 48 seconds.
Email us at alienstacksth@gmail.com or use the contact page and we will arrange a thirty-minute conversation — in Thai or English, by video, or at our Bang Na office if you would rather see where we work. We will sign a mutual NDA first if you want one. Tell us what the business needs to do differently; we will tell you whether custom software is the right answer, what it realistically involves, and whether we are the right team. We decline work that is a poor fit rather than take a deposit and find out later.
If it fits, we scope a small paid first milestone that ends with something deployed and testable in one branch, so your commitment stays small until we have earned more of it. If you already have a half-built system from another developer, ask about the architecture review instead — two to five days, a written verdict in Thai or English, and no obligation afterwards.
We are a Thai company. Alienstacks Co., Ltd. is registered with the Department of Business Development under Reg. No. 0395569000469, with our head office in Bang Na, Bangkok, and a second operation in Tokyo. You can look up the registration, visit the office, and sit across the table from the engineer who will design your system. For a Thai or regional SME that is the single biggest risk reducer available: the vendor is a legal entity in your own jurisdiction, not an email address in another hemisphere.
Thai and English are our working languages for client projects, and we also operate in Japanese through our Tokyo side. Documents, specifications, and written updates can be delivered in Thai or English, whichever your team reads faster — we generally write specifications in English for engineering precision and hold meetings in Thai when that is more comfortable for the people who actually run the business. For products aimed at Vietnam, Indonesia, or the Philippines we build the localisation layer properly rather than bolting translation on at the end.
You own all of it — repository, cloud accounts, app store listings, CI configuration, and deployment credentials. Where possible we work directly inside your own GitHub organisation and cloud tenancy so ownership is never a handover risk. There is no proprietary Alienstacks layer you have to keep paying for and no technical reason you cannot move to another team. Many regional SMEs have been burned by a developer who kept the hosting account as leverage; we structure around making that impossible.
Yes. Contracts can be executed under Thai law with Thai courts as venue, in Thai, English, or a bilingual document. As a registered Thai company we issue VAT tax invoices and receipts, and we handle the withholding tax mechanics on service fees the way your accounting team expects, so nothing about the paperwork is unusual for your bookkeeper. For clients elsewhere in ASEAN we invoice in USD or the local currency and can contract under Singapore law where that is preferred for cross-border comfort. We also sign mutual NDAs before discovery, and we build with Thailand’s Personal Data Protection Act in mind rather than treating privacy as an afterthought.
This is one of our deepest areas. Our team architected point-of-sale software now running in more than 10,000 stores across Southeast Asia and processing over $50M in annual transactions, which meant integrating card terminals from multiple manufacturers, the national QR payment standard, e-wallet rails, and cash handling — all of it reconciling exactly at end of day. We also built cross-border settlement with fee deduction and escrow for a two-country marketplace, and QR-based ticketing for a smart bus network. Cross-border QR interoperability between the Thai, Singaporean, Malaysian, and Indonesian schemes is an area we track closely because our retail clients ask for it.
It has to, and this is exactly why we design offline-first. A till that stops selling when the connection drops is commercially unacceptable, and it is the failure that ends most cheap POS builds in this region. Every transaction is journaled locally first and synced afterwards, with idempotent handling so a retry never creates a duplicate charge and a reconnect never loses or double-counts a sale. We built that model for a deployment spanning more than 10,000 stores including many in second- and third-tier cities, and we bring the same pattern to field service apps, delivery apps, and market-stall commerce.
Very common here, and we take it on without judgment. The first step is a paid architecture review of two to five days: we get the codebase running, read the data model, check how payments and credentials are handled, see what tests exist, and give you a written verdict in Thai or English on what is worth keeping. Sometimes the front end is fine and the backend must be rebuilt. Sometimes the honest answer is that starting again costs less than repairing it, and we will tell you that even though the bigger-sounding rebuild is not always what we would prefer to sell. The report is yours whether or not you continue with us.
