How It Works

Live in under 5 minutes.

Most of the setup is automated. CreditGuard handles the configuration — you only need to add one checkout block manually.

Automated — < 2 minutes

Install from the Shopify App Store

Click install. CreditGuard immediately begins four automated setup tasks in parallel:

Creates the credit_management.credit_limit metafield definition on company locations
Registers a payment customisation that hides 'Pay on Account' for suspended or over-limit accounts
Registers the checkout cart validation with blockOnFailure enabled
Syncs all your existing B2B companies and locations into CreditGuard

Add the checkout block

After setup, CreditGuard shows you step-by-step instructions with screenshots to add the CreditGuard block in the Shopify checkout editor. This block shows buyers their credit status and the 'submit for approval' button when needed.

Instant enforcement

Set your first credit limit

Open any company, navigate to a location, enter a credit limit, and save. That location is now enforced. The limit syncs instantly to Shopify metafields — no delay.

Background task

Pre-install sync runs automatically

The first time you open any location page, CreditGuard fetches all unpaid orders that existed before you installed the app and imports them into the credit balance automatically. A live progress banner keeps you informed.

Order Lifecycle

How every B2B order interacts with CreditGuard.

Every checkout runs through the same validation function. Here's what happens on each path.

Buyer completes checkout

Checkout Validation Function runs (server-side, zero DB calls)

Check 1: Is account suspended?

Check 2: Does location have overdue invoices?

Check 3: Cart + outstanding > credit limit?

Passes all checks

Order created in Shopify

CreditGuard webhook reserves credit

Balance updated

Invoice tracked with due date

Payment received → credit released

Payment stats updated

Fails any check

Buyer sees block message

Buyer clicks 'Submit for approval'

Draft order created with CREDIT_APPROVAL_REQUIRED tag

Shopify Flow trigger fires → merchant notified

Merchant reviews & approves draft

Draft converted to order → credit reserved automatically

Buyer Experience

What your buyers see when blocked.

Every block reason shows a distinct, clear message. Buyers are never left confused about why their order was stopped.
