Accounts payable automation for financial services firms in Vietnam

Financial services firms buy a wide range of goods and services to keep operating: technology licences and cloud services, data and market information, consulting and legal advice, outsourced services, branch premises and facilities, marketing, security and office supplies. Each purchase produces vendor invoices, and in Vietnam most of them are e-invoices that must be checked before they are booked.

Those invoices rarely belong to a single budget. One technology contract may be shared between several departments; branch costs belong to the branch cost centre; group services may be recharged between legal entities. Finance teams need each invoice coded to the right cost centre and entity before it is approved, and they need that coding to be consistent from month to month.

Approval rules are also more formal than in most industries. An approval matrix sets who can approve which amounts for which cost centres. The person who enters an invoice should not be the person who approves it, and the person who approves it should not be the person who releases the payment. Internal audit, external auditors and management all expect to see this segregation of duties in the records, not only in a policy document.

• Vendor invoices spread across many cost centres, departments and legal entities.
• Approval matrices by amount and cost centre that must be applied every time.
• Segregation of duties between entering, approving and paying invoices.
• Audit requests that need the complete history of a payment, quickly.

BancoOS is an accounts payable and finance operations platform. It covers the vendor invoice, its approval and the payment that follows, plus accounts receivable on the same ledger. It is not a core banking system, a customer onboarding or identity verification tool, or a regulatory reporting system. Those processes stay in the systems your institution already uses for them.

Keeping this boundary clear helps when you plan a rollout. The finance team can start with a well-defined queue of vendor invoices, with known source documents, reference numbers and approvers, without changing how customer-facing operations work.

A practical first step is to list the vendor invoices your team handles today: where they arrive, who codes them to a cost centre and entity, who approves them at each amount, and where the approval evidence is kept. That list becomes the scope of the first workflow, and it shows quickly where manual re-keying, missing purchase orders or unclear approvers are slowing the month-end close.

BancoOS takes a vendor invoice from arrival to payment in one workflow and posts the result to your accounting system. The capabilities below are the same ones described on the finance automation platform page.

• Invoice capture: invoices arriving by email or upload are read by AI document capture, with a confidence score for each extracted field so uncertain values go to a person for review.
• Tax Department (Cục Thuế, formerly GDT) e-invoice validation: every inbound supplier invoice is validated against the GDT registry, so invoices that fail validation are stopped before they reach your books.
• MST supplier checks: the vendor's tax code is looked up against the tax registry, so the legal name, address and taxpayer status come from the registry rather than from typing.
• PO, goods receipt and invoice matching: where a purchase order and a goods or service receipt exist, BancoOS performs 3-way matching and flags differences as exceptions.
• Approval routing by amount and cost centre: the workflow builder lets finance leaders define approval policies by amount, vendor, cost centre or any field extracted from the document, with four-eyes controls where a second approver is required.
• Payment preparation: approved invoices are prepared for payment through Vietnamese banks, and payments are reconciled.
• Audit trail: every capture, validation result, approval and change is recorded.
• Multi-entity: multi-entity, multi-currency, multi-VAT and multi-bank setups are supported for groups with several legal entities.

For purchases backed by a purchase order, such as hardware, outsourced services or facilities work, 3-way matching is the core control. Our 3-way matching guide explains what must agree between the purchase order, the goods receipt and the invoice, and how to deal with common exceptions.

If your firm also issues invoices to customers, accounts receivable runs on the same ledger: customer invoices, receipts, aging and collections, with customers identified by MST in the same way as suppliers.

In financial services, finance operations are reviewed closely. BancoOS is designed so the evidence of each control is part of the record.

• Audit chain: every step in the life of an invoice, from capture to payment, is recorded with the user and time, so you can retrieve the full history of any payment.
• Role-based access: users see and act only on what their role allows, which supports segregation of duties between entering invoices, approving them and releasing payments.
• Data handling: TLS 1.3 in transit, AES-256 at rest, tenant isolation, SSO/SAML and in-region hosting.

Institution-specific requirements, such as particular regulatory obligations, document types or internal policies, require separate confirmation of product scope, integrations and controls before you rely on them.

BancoOS works alongside your accounting system rather than replacing it. Posted entries flow back to the system of record, and validation runs against the e-invoice system. See the setup, data flow and troubleshooting pages for each connector:

• MISA integration: map vendors, chart of accounts, cost centres and tax codes, then push posted entries back into MISA.
• Microsoft Dynamics 365 Business Central integration: keeps Business Central as the financial system of record while BancoOS handles AP capture, matching, approvals and payments.
• GDT e-invoice integration: real-time validation of inbound supplier invoices against the GDT registry.

If your finance team handles vendor invoices across many cost centres and entities and wants one controlled workflow from invoice to payment, we would like to understand how it works today. Contact the BancoOS team to discuss your accounts payable process and confirm what fits your scope.
