How data flows between Saeree ERP modules
Saeree ERP runs 16 modules on a single database — from budget planning, requisition, procurement, inventory and fixed assets through to accounting, finance and human resources. Data entered once flows through every downstream step without re-keying, and remaining budget updates the moment a document is approved.
We organize our solutions by type of organization rather than by company size, because what really shapes daily work is the regulations and budget structure an organization has to comply with. Government agencies, public organizations and private companies therefore run different module sets and different approval workflows.
An approved requisition draws down the budget, generates the purchase order, receives goods into inventory, records the payable and posts to the general ledger — all in one continuous chain. That removes duplicate keying and the discrepancies that come with it.
Define multi-level approval routes by organizational structure, spending limit and document type. Approvers are notified by email and LINE, and every approval step is recorded — who approved what, and when.
Our consultants study your existing regulations and processes first, then design the chart of accounts, budget structure and report formats to match what you actually have to submit — instead of asking your organization to bend around the software.
Each segment works under different regulations, budget structures and operating cycles — so the module set and the workflows are laid out differently for each.
Government
Government work runs on the fiscal year and procurement regulations, so the system has to control the balance at every stage — appropriation, reservation, commitment, accrual and actual disbursement — with a full audit trail on every document.
Clients: Office of the Permanent Secretary for MHESI, Election Commission of Thailand
Public Organizations
These organizations spend government appropriation, own revenue and grant funding at the same time. The system has to separate the funding source from the very first document through to the financial statements — not reconcile it by hand afterwards.
Clients: NSM (state enterprise), TGO, BEDO, ARDA, SAC, Thai Media Fund
Services
Service businesses bill on a monthly cycle across a very large customer base. The real workload is issuing every invoice on time and matching each payment to the right one.
Client: Charoen Ying Co., Ltd. — cable TV, 100,000+ customers, 30+ branches
Trading
Margin in trading lives in purchase price and stock levels. The system has to tie every purchase order, goods receipt and invoice together before that margin disappears into slow-moving inventory.
Client: KC Mahanakorn Co., Ltd. (industrial valves)
Manufacturing
A factory needs cost per product line and raw materials ready ahead of the run. That means the production plan has to connect to raw-material inventory and cost accounting — not sit in a separate spreadsheet.
Clients: Bangkok Rubber PCL, Chaiwatana Tannery PCL
Education
When staff are spread across the country, the hard part is attendance, leave and getting payroll out on schedule — while head office still needs the full picture in one place.
Client: Office of the Teachers' Welfare Commission — 700+ staff nationwide
Every module sits on the same database. Organizations can switch on only what they need first and add the rest later without migrating to another system.

Current ISO/IEC 29110-4-1:2018 certificate (2024–2027)
ERP projects rarely fail because a feature is missing — they fail because delivery has no discipline behind it. We work under ISO/IEC 29110-4-1:2018, certified by TÜV NORD, and have held that certification continuously for 10 years since 2015. The current certificate runs to 12 November 2027.
On the tax side, the software has held the Thai Revenue Department software standard since 2009, and supports e-Tax Invoice & e-Receipt with digital signatures.
We gather input from the people who do the work — the forms in use, the reports you have to submit, and the approval routes as they stand today.
We configure the budget structure, funding sources, chart of accounts, and role-based permissions for each position in the organization.
Existing data is loaded and reconciled against the old system until the balances agree, before you cut over to live operation.
Training is delivered per user role, with a support team on hand after go-live and ongoing adjustments as regulations change.
Saeree ERP deploys either on-premise on servers inside your organization, or in the cloud on your own cloud account. Either way the data sits on infrastructure your organization owns outright — we do not operate a multi-tenant SaaS that pools data from many organizations, so none of your data lives on our servers.
SSL Grade A+ encrypted connections, two-factor authentication (2FA), role-based permissions, and logs of every action recording who did what and when.
An open API connects to external systems such as GFMIS, e-Office, banking systems and payment gateways — so you don't have to replace everything at once.
Built with Angular and PrimeNG on the front end, a Jersey Java REST API on the server side, and PostgreSQL for the database — see the full architecture.
Two-factor authentication (2FA) can be enabled on every user account
