For Shopify wholesale & B2B stores

Block overdue customers from ordering again

Shopify gave every plan net terms in April 2026 — but nothing stops a stockist with three unpaid invoices from placing a fourth. PaidUp blocks their checkout automatically until they settle, and enforces a credit limit per account.

How it works

1
Add your net-terms accounts

Pick the wholesale buyers you invoice on terms, and set each one's Net 15/30/60 and credit limit.

2
PaidUp watches their balance

Every unpaid order becomes an invoice with a due date. PaidUp tracks what each account owes and how late it is.

3
Checkout stops them automatically

Past your grace period, that account simply cannot check out until it pays. No draft-order review, no manual toggle, no Flow to maintain.

What Shopify does not do for you

Real blocking, not a reminderShopify sends up to five payment reminders and then stops. PaidUp is the part that actually prevents the next order.
Credit limits enforcedGive an account USD 5,000 of rope. When the cart would take it past that, checkout says so and stops — before you ship.
Every checkout pathStorefront, B2B, draft orders and accelerated checkouts — Shop Pay, PayPal, Google Pay, Apple Pay. Not a theme tweak that express checkout skips.
Nothing to maintainShopify's own answer is to flip a company to "submit orders as drafts for review", by hand, per customer, and remember to flip it back. PaidUp does it off the balance, automatically.
Works on every planNo Shopify Plus required. Your accountant keeps doing the books in QuickBooks or Xero — this is the credit-risk layer neither of them has.
Reminders and ledger includedInvoice aging, automatic reminder emails and CSV export come with it. They just are not the point.
