FAQ
Who can use FlexiBill?
FlexiBill is available to Corporate and International merchants on DOKU Dashboard who have completed KYB (Know Your Business) verification. Personal merchant accounts are not eligible.
Can FlexiBill automatically charge customer cards without them having to pay manually each cycle?
Yes. Account Billing — FlexiBill's auto-debit engine — allows you to securely store a customer's card or bank account credentials once and automatically charge them on schedule, whether daily, weekly, monthly, or annually. Customers do not need to take any action after the initial registration.
This is separate from Subscription and Billing, which sends invoices that customers pay manually via a payment link. Choose Account Billing when you need fully automatic, invisible payment collection. → Learn more about Account Billing
What is the difference between Subscription and Billing and Account Billing?
Both handle recurring billing, but they work differently:
How customers pay
Manually via payment link in invoice or auto debit
Automatically charged — no customer action needed
Billing trigger
Invoice issued → customer pays
Card charged directly on schedule
Best for
Businesses where customers are accustomed to receiving and settling invoices
Businesses that need seamless, invisible auto-debit (SaaS, insurance, memberships)
Payment method
Any available payment method
Credit Card (RECURRING/MOTO) or Direct Debit only
Use Subscription and Billing for invoice-based collection. Use Account Billing for fully automatic card-on-file charging.
What is the difference between FlexiBill and a Payment Link?
FlexiBill is a recurring billing platform — it manages subscription lifecycles, automates invoice generation on schedule, and tracks member payment statuses across multiple cycles. A Payment Link is a single-transaction tool that requires a new link to be created manually for each payment, with no recurring logic, member management, or billing cycle automation.
Can FlexiBill handle billing for hundreds or thousands of customers at once?
Yes. FlexiBill supports bulk billing through two methods: uploading a billing data file (CSV/XLSX) via the Dashboard for up to 1,000 rows per file, or using SFTP batch file upload (available via Account Billing) for high-volume operations at scale. Both automatically generate and deliver invoices to all customers in the batch.
Can FlexiBill send invoices via WhatsApp?
Yes. When combined with DOKU PayChat, FlexiBill's Subscription and Billing feature can broadcast invoices and receipts directly to customers via WhatsApp. PayChat must be activated separately. Account Billing does not use WhatsApp — charges are executed silently on schedule with a notification sent after each transaction.
Can customers choose their own subscription plan without contacting the merchant?
Yes. Using the Pricing Table feature in Subscription Lifecycle Management, merchants can create a shareable plan selection page that can be distributed via URL or embedded into a website. Customers browse available plans, select one, verify their email, and complete the first payment — entirely self-served. → Learn more about Pricing Table
Is customer card data stored securely?
Yes. FlexiBill's Account Billing feature uses PCI-DSS compliant tokenization managed by DOKU. Sensitive card data — card numbers, CVVs, and expiry dates — never touches the merchant's server. Merchants work with secure tokens only, and DOKU handles all credential vaulting and storage.
