Frequently asked questions
Everything about plans, channels, privacy and accounting.
What is VieBoost?+
VieBoost is a free Android app for Vietnamese household businesses selling over personal Zalo and Messenger. It gathers customer messages in one place, creates orders straight from a message, sends bills with a QR code for the exact amount, marks orders paid when the money arrives, tracks inventory, receivables and cash flow, and keeps the household ledgers required by Circular 152/2025.
Is VieBoost free?+
Yes. Install the app and the Free plan works right away, no account and no card needed. Free includes 2 channels, 1 account per channel, up to 10 bills a day and the Circular 152 ledgers. To try the Basic plan free for 15 days, create an account with your email in the app, still no card; when it ends you drop back to Free. Paid plans add channels, accounts and reports, paid by VietQR bank transfer or card. Cancel anytime, no long-term contract.
Which channels does VieBoost support?+
Currently personal Zalo and Facebook Messenger (read via Android notifications, even two Zalo accounts on one phone). Zalo OA, Facebook Pages, Shopee and TikTok are in development and not available yet.
Does VieBoost spy on messages or upload my data?+
No. VieBoost only READS notifications to show them to you. All messages, orders, contacts and books are stored 100% on your device (on-device, zero-knowledge). VieBoost servers only know your account and plan — never your business content.
Where are my orders and receivables stored?+
100% on your device (local SQLite). VieBoost servers store no message content, orders or receivables — only login + subscription. Uninstalling wipes everything.
Does VieBoost auto-reconcile bank transfers?+
Yes. VieBoost reads balance-change notifications from ~30 Vietnamese banks and auto-matches them to orders by the transfer note, so income/expense reconciliation is accurate without manual hunting.
How does VieBoost send QR bills directly over chat?+
Long-press the customer’s message → VieBoost creates a sale order with a VietQR bill → sends it straight into Zalo/Messenger. The customer scans the QR to transfer the exact amount with the right note — no copying account numbers or typing. All inside the chat.
Will my Zalo account get banned?+
Near-zero risk with normal use — 1–2 devices, natural messaging. VieBoost reads via the native Android notification API and does not reverse Zalo’s protocol. Absolutely no spamming or mass-sending.
Can VieBoost generate accounting books?+
Yes. From orders and payments it builds cash flow, P&L, inventory, receivables, balance sheet and accounting books, exportable to Excel to print or file. Household businesses use the Circular 152/2025/TT-BTC set (mandatory from 01/01/2026): S1a-HKD, S2a-HKD and the four S2b, S2c, S2d and S2e-HKD books for households paying PIT on taxable income; a Circular 58/2026/TT-BTC set is also available for those opting into the micro-enterprise regime. It is a bookkeeping aid, not tax advice.
Where do I download VieBoost and which Android does it need?+
Search "VieBoost" on Google Play or go to vieboost.vasbook.com/download. It runs on Android 7.0+ and installs in about 2 minutes. There is no iPhone version yet; iPhone users can download the free Excel ledger templates. Need help installing? Message Zalo 0386 959 888.
How do I cancel a paid plan?+
Go to Account → Plan → Cancel. After cancelling you keep access until the paid period ends, then drop to Free — no extra charge, no long-term contract.
