Finance automation for multi-store retailers in Vietnam

• Volume: a 40-store chain typically handles 4,000–8,000 supplier invoices a month across food, packaging, logistics, rent, utilities and marketing — most arriving as e-invoice XML plus a PDF, from suppliers who each use a different issuing provider.
• Fragmentation: store managers approve locally, accounting posts centrally, and the two rarely see the same version of the document. Disputes surface weeks later, after payment.
• Compliance: input VAT can only be deducted on a valid e-invoice. If a supplier's invoice was never properly issued to the tax registry, the deduction is at risk — and nobody notices until the annual finalisation.
• Seasonality: Tết, mid-autumn and promotional cycles compress ordering, receiving and payment into short peaks that manual processes cannot absorb without hiring.

• Store-level invoice intake by email, upload or supplier portal, routed by cost centre and approval limit.
• GDT-validated e-invoices for every supplier and tenant, checked at the moment of receipt.
• 3-way matching of purchase order, goods receipt and invoice — including partial and over-deliveries common in fresh categories.
• POS settlement and bank reconciliation, daily rather than monthly.
• Cash-flow forecasts that account for seasonality, promotions and supplier payment terms.
• Rent, utilities and franchise fee schedules tracked as recurring commitments, not surprise invoices.

Vietnam's e-invoicing regime (Decree 123/2020/ND-CP, implemented through Circular 78/2021/TT-BTC) requires invoices to be issued electronically and registered with the General Department of Taxation. For a buyer, the practical consequence is that a PDF in an inbox proves nothing on its own. BancoOS checks each inbound invoice against the GDT registry — seller MST active, invoice serial and template registered, issue date in range, total matching — and stores the registry response alongside the document as audit evidence. Where a store receives a paper or scanned invoice, it is captured, digitised and flagged for the same check so the exception is visible immediately instead of at finalisation.

• Seller tax code (MST) verified as active and matched to the supplier master.
• Invoice serial and template confirmed as registered with the GDT.
• VAT rate and amount checked against the line detail and the supplier's contract.
• Duplicate detection across stores, so the same invoice is never paid twice.
• Registry response retained per invoice for tax audit and VAT finalisation.

Retail cash does not reconcile itself. Card acquirer settlements, e-wallet payouts (MoMo, ZaloPay, VNPay), cash deposits and bank fees each arrive on their own schedule, net of their own deductions. BancoOS ingests POS settlement files and bank statements, matches them to expected takings per store per day, and raises an exception when a deposit is missing, short, or late — while the CCTV and shift records that explain it are still accessible.

Not every retail sale settles at the till. Corporate gifting, franchise partners, wholesale accounts and mall or concession operators all pay on terms, and those balances usually live outside the POS. BancoOS records each customer invoice, applies receipts against it with the bank reference attached, and derives outstanding balance, aging and overdue days from the ledger rather than a spreadsheet. Collections activity is logged per invoice, so the team can see who has been chased and what was promised.

BancoOS is not a replacement for your accounting system. It sits in front of it: capturing, validating, matching and approving, then posting clean entries to MISA, Microsoft Dynamics 365 Business Central or your existing ERP. Store systems keep working as they are; finance stops re-keying.

• Invoice cycle time from receipt to approved-for-payment.
• Share of invoices processed without human touch.
• Exceptions per thousand invoices, by store and by supplier.
• Days between POS settlement and confirmed bank reconciliation.
• Input VAT at risk from unvalidated invoices — ideally zero.
