All Flowly features
Every financial document a Thai business needs.
Quotations
Free online quotation generator
Line items → VAT/discount → download PDF. Send to clients with no watermark, no branding lock-in.
Invoices
Free online invoice generator
PromptPay QR on every invoice, VAT/WHT computed automatically, status tracked, reminders sent for you.
Receipts
Issue receipts online
Mark an invoice as paid → Flowly auto-generates a receipt with payment method and date.
Tax invoices
Thai full tax invoices (VAT 7%)
VAT-registered? Flowly issues full tax invoices with auto-numbering and Revenue Dept-compliant fields.
Withholding tax
Thai 3% withholding tax auto-calculated
Thai corporate clients withhold 3% — Flowly shows the real amount they'll transfer so you stop doing math.
Billing notes
Free online billing note (pre-invoice notice)
Thai B2B teams expect a billing note before the real invoice. Flowly issues them in one minute and converts to the actual invoice when it's time to collect.
Credit notes
Thai credit note (reduce an issued invoice)
Thai VAT-registered businesses must issue credit notes to adjust output VAT. Flowly links each credit note back to its source invoice for a clean audit trail.
Debit notes
Thai debit note (increase an issued invoice)
Thai VAT rules forbid editing a sent invoice. A debit note adjusts the amount legally — Flowly links it back to the original invoice automatically.
PromptPay QR
Invoices with PromptPay QR
Set your PromptPay ID once. Flowly adds the QR to every invoice so clients pay faster with fewer bank-detail mistakes.
Income & expenses
Income and expense tracking for small businesses
Flowly combines paid invoices and categorized expenses so freelancers and small teams can see monthly profit clearly.
Recurring invoices
Recurring invoices for monthly retainers
Set recurring invoices for retainers, rent, maintenance, or monthly services, then let Flowly help you keep each billing cycle visible.
