Pro
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShopify lets you sell B2B on net terms, but it sends no real invoice and never chases a late payment. Onopo does both. When a B2B order with payment terms comes in, it creates a numbered PDF invoice with your logo, tax breakdown and bank details, and emails it to the buyer automatically. A dashboard shows what is open, due soon and overdue.
Shopify gave every plan net terms, but nothing stops a stockist who already owes you for three invoices from placing a fourth. PaidUp is that missing piece. Set each wholesale account's terms and credit limit. Once an account is past your grace period, checkout refuses it until the invoices are settled, and unblocks the moment they pay.
