Onopo
Now on the Shopify App Store

Shopify gives you net terms.
Onopo gets you paid.

Since April 2026 every Shopify plan can sell B2B on payment terms — but Shopify still sends no real invoice and never chases a late payment. Onopo does both, automatically.

What most merchants do today

Export the order, rebuild the invoice in Word, email it, note the due date in a spreadsheet — and three weeks later dig through your inbox to work out who still hasn't paid. That's an afternoon a week you don't get back, and money that arrives later than it should.

Everything that happens after the order

Invoices your buyer's accounting accepts
Every B2B order with payment terms becomes a proper PDF: sequential number, tax breakdown, your logo, bank details and due date.
Sent automatically
The invoice reaches your buyer the moment the order comes in. No manual step, no copy-paste, no forgotten invoice.
You always know who owes what
One dashboard for open, due and overdue receivables — with totals, aging, and what is landing this week.
Reminders that escalate
A friendly nudge before the due date, firmer wording after. Configurable stages, weekend protection, and a pause switch while you negotiate.
Built for the real world
Multi-currency, VAT and reverse-charge notes, resend on request, and a log of every message sent — proof when you need it.
Works with native Shopify B2B
No parallel system. Onopo reads companies, price lists and payment terms straight from Shopify. Live in minutes.
