Localized ERPNext - End-to-end management for Vietnamese enterprises
Open-source ERPNext, fully localized to Vietnamese Accounting Standards (VAS), integrated with e-invoicing, banks and e-tax. Implementation and running costs are a fraction of SAP/Oracle, with unlimited customization.
Open source - no lock-in, no license fees
ERPNext is the world's leading open-source ERP, deployed by 10,000+ companies. Mantis Tech is a trusted implementation partner in Vietnam with a complete localization package: VAS accounting, VAT returns, financial statements per Circular 200/133, e-invoicing via Viettel/VNPT/M-Invoice, bank connectivity (Vietcombank, Techcombank, VPBank) and payment gateways.
Unlike closed solutions, ERPNext allows unlimited customization: add DocTypes, create workflows, write reports, integrate APIs — all through the UI or in Python. When your processes change, the system changes with them, no vendor negotiation required. You own the code and the data.
Mantis Tech delivers end-to-end implementation — discovery, design, configuration, training, go-live — in 8-16 weeks depending on scope. Post go-live, we provide monthly managed support with clear SLAs. Notably, we run our own business on ERPNext — we don't just sell it to clients.
