The Plan screen shows which plan your business is on, how much is used this month, how the plans compare, and your payments.
Who can see it: Owner and Manager. Only the owner can pay; managers see the line The business owner pays.
Your current plan
The Current plan section shows the plan name, the monthly price, the end date (e.g. Paid until 30/11/2026) and Usage:
- AI conversations in 11/2026: used against what the plan includes.
- Connected channels: channels taking up a place.
- AI assistants: assistants created.
At 80% an "Almost used up" line appears; when something is used up, a message says what happens. More detail is on Usage.
Plans and limits
| Plan | Price per month | AI conversations per month | AI assistants | Messaging channels |
|---|---|---|---|---|
| Free | ₫0 | 100 | 1 | 1 |
| Pro | ₫499,000 | 1,500 | 2 | 2 |
| Business | ₫1,490,000 | 5,000 | 5 | All channels |
Prices exclude VAT; at checkout the screen shows any VAT and the total. The Business card also lists Edit your intake flow and API access, but these are not available on screen yet: for now, ask COREBIZS.
One AI conversation is the messages with one customer within 24 hours of the assistant's first answer. A channel with a problem still takes up a place until you disconnect it.
Paying
- Under Self-service plans, press Choose Pro (or another plan), or Renew on your current plan.
- Choose the Period: 1 month or 12 months. 12 months costs 12 times the monthly price; there is no yearly discount.
- Fill in the E-invoice details: Business or buyer name, Tax code (if any), Address, Email for the invoice.
- Press the pay button with the amount, e.g. Pay ₫499,000. You go to the Pay2S page.
- Scan the QR code with your banking app and keep the amount and transfer content unchanged. The payment page stays valid for 30 minutes.
Only QR bank transfer is available. Card payment, e-wallets and automatic charging are not available yet.
If the screen says Online payment is not available yet. Message COREBIZS on Zalo OA to upgrade., message COREBIZS.
When your plan is updated
After the transfer, go back to the Plan screen:
- Usually within a minute it shows Payment received. The Pro plan is paid until 30/11/2026. The e-invoice will be sent to the email you entered.
- The plan only changes when the bank confirms the right amount. If you transferred a different amount, the plan is not extended automatically: message COREBIZS with the transfer content.
- Nothing after 30 minutes: message COREBIZS with the transfer content.
E-invoice
The invoice is issued automatically once the money arrives and sent to the email you entered. Payments lists each payment with its invoice status, e.g. Invoice no. 0000123 or Invoice being issued. If it shows COREBIZS will email the invoice, COREBIZS is handling it; your plan is not affected.
The buyer details are saved to fill in next time and only the owner sees them. Press Delete the saved details to remove them; invoices already issued keep their own copy. To cancel or adjust an issued invoice, contact COREBIZS.
Renewal reminders and expiry
- 7 days and 1 day before the end date, owners and managers get a bell notification and an email.
- When the plan ends, your business keeps it for 7 more days (grace period); the screen shows the last day.
- If it is not renewed after those 7 days, your business moves to the Free plan. No data is deleted and connected channels stay; the assistant answers within the Free plan's limits, and you cannot connect channels beyond them.
- Paying at any time turns the plan back on straight away.
Switch plans
- Renewing the same plan: the new period continues from the current end date.
- Switching between Pro and Business: the new plan starts at once; the days left on the old plan are converted into extra days on the new one.
- From the Free plan, or after the plan has ended: the new plan starts at once.
Not available yet: refunds (including what is left when moving to a cheaper plan). Contact COREBIZS if you need one.
Managed plans
Businesses on AI Starter, AI Business, AI Integration or Dedicated pay under their contract with COREBIZS, outside the app. The Plan screen shows only the current plan, By contract or the monthly price, usage and a note: the assistant keeps answering past the included conversations and the overage is billed under the contract. There is no pay button. To change plans, contact COREBIZS.
