Activate Your Subscription
After sign-up and your first test call, you’ll need to activate your subscription to unlock the full capabilities of Voice Logica. This guide walks you through adding a payment method and choosing a plan.
The Demo Plan
Section titled “The Demo Plan”When you first sign up, your account starts on the Demo Plan with limited resources for initial testing:
- Minutes: Limited call time for testing
- Emails: Limited email sends
- SMS: Limited SMS messages
These resources let you test Voice Logica’s features before committing to a paid plan. To view your exact Demo Plan allocation, check the Resources panel in the sidebar or visit Subscription & Billing.
What you see on the dashboard
Section titled “What you see on the dashboard”When payment is still missing, the home dashboard shows a NEXT STEP card such as Configure payment method, plus a Finish setting up Voice Logica checklist. Typical checklist items:
- Download the Windows / mobile app
- Build your first AI agent (often already done from onboarding)
- Do your first call
- Configure payment method
- Choose the subscription
- Get your free phone number (optional; may stay locked until a plan is active)

Activating Your Subscription
Section titled “Activating Your Subscription”To activate your subscription and unlock full features, you need to complete two steps:
- Add a payment method (with VAT/Tax ID)
- Choose and activate a paid plan
Let’s walk through each step.
Step 1: Add a Payment Method
Section titled “Step 1: Add a Payment Method”Before you can activate a subscription, you need to add a payment method with your VAT/Tax ID information.
-
Open the payment flow
On the dashboard, click Add payment method on the NEXT STEP card, or Add card on the checklist row. You can also navigate to Subscription & Billing from the sidebar and select the Payment Details tab.

Enter VAT and billing email
Before connecting to Stripe, Voice Logica asks for:
- VAT code (Tax ID) — Your business tax identification number
- Billing email — The email address where invoices will be sent
Important: Use the correct VAT format for your country:
- Start with a 2-letter country code (e.g.,
EL,DE,FR,CY) - Follow with 8-12 alphanumeric characters
- No spaces or punctuation
- Examples:
EL012345678(Greece),DE123456789(Germany),CY12345678X(Cyprus)
Make sure the billing email is an inbox your finance team can access for invoices.

Continue to Stripe
Click Continue to Stripe. You’ll be redirected to Stripe Checkout, a PCI-compliant payment processor trusted by millions of businesses worldwide.
Voice Logica never stores your raw card details on its own servers — all payment information is securely handled by Stripe.

Save your card
On the Stripe Checkout page, enter:
- Card number
- Expiry date
- CVC security code
- Cardholder name
Click Save when ready. After Stripe processes your information, you’ll be returned to Voice Logica with your payment method on file (displayed as the card type and last four digits, e.g., “Visa ending in 1234”).

Step 2: Activate Your Subscription
Section titled “Step 2: Activate Your Subscription”With your payment method saved, you can now choose a paid plan and activate your subscription.

Open Subscription management
Navigate to Subscription & Billing from the sidebar, then click the Subscription management tab.

- Monthly minutes — Call time included per month
- Emails — Email messages you can send
- SMS — SMS messages for notifications
- Concurrent calls — How many simultaneous calls your agents can handle
- Features — Access to integrations, API, outbound calling, etc.
Consider:
- How many call minutes you expect per month
- Whether you need integrations (Google Calendar, CRM systems)

-
Choose your plan
Click Choose a plan or Select on the plan card that best fits your needs.
-
Confirm activation

- Verify the number with your country’s tax authority
- Contact support with your company legal name and Tax ID for manual verification
How do I get more Demo Plan resources?
Demo Plan resources are intentionally limited to encourage testing without committing to a paid plan.
If you need more resources:
- Activate a paid subscription to unlock higher limits
- The cheapest paid plan offers significantly more resources than Demo
- You can always downgrade or cancel after testing if needed
Demo resources are NOT expandable — they’re designed as a fixed testing allocation.
When will I be charged?
First charge:
- Occurs immediately when you activate a paid subscription
- Amount equals the monthly cost of your chosen plan
Recurring charges:
- Happen automatically on your billing date each month
- Billing date is set when you first activate a subscription
- You can view your next billing date in Subscription management
Prorated charges:
- Upgrades are prorated — you only pay for the remaining days of your billing period at the new rate
- Downgrades take effect at the next billing cycle, so no proration occurs
