GoUp Approved Customer Invoice Gateway

Plugin slug: goup-approved-customer-invoice-gateway · Version: 1.0.5 · Author: GoUpWP · https://goupwp.com/plugins/approved-customer-invoice-gateway

What it does

Adds a Pay by Invoice payment method to WooCommerce that is offered only to customer accounts you have individually approved. Guests, unapproved accounts and roles never see it — approval is per user, never per role. Approved customers place the order without paying online; the order lands in the status you choose and your invoice terms are recorded on the order.

Works with the classic checkout and the Checkout Block, and with HPOS.

Installation

1. Download the plugin ZIP from your GoUpWP account (Account → Licenses → Download).
2. In WordPress go to Plugins → Add New → Upload Plugin, choose the ZIP and click Install Now, then Activate.
3. WooCommerce must be installed and active; the plugin shows a notice and stays idle until it is.
4. Open WooCommerce → License: Approved Customer Invoice Gateway and paste the license key from your account. Activation unlocks one-click updates and support for this site. A localhost, *.test, *.local or staging. site counts as a staging activation and does not use your production seat.

The plugin keeps working if the license expires: only updates and support pause until it is renewed.

Setup

1. WooCommerce → Settings → Payments → Pay by Invoice: enable the method and set the title and description customers see, the order status after checkout (On hold is recommended), the default invoice terms (e.g. "Net 30"), and the instructions shown on the thank-you page and in customer emails.
2. WooCommerce → Invoice Customers: search by name, email, username, company or user ID and click Approve. Bulk approve/revoke is available, and the Approved / Not approved filters show who has access.
3. Optional per-customer overrides live on the user's profile (Users → Edit): custom invoice terms and an internal note that is never shown to the customer.

How eligibility is checked

• The gateway is available only to logged-in users whose account is approved, at every step: when checkout loads, when the order is placed (classic and Store API), and on the "pay for order" page — a customer can only use it for their own orders.
• Approval, terms and the approval timestamp are snapshotted on the order, so revoking a customer later never changes historical orders. The order screen shows both the snapshot and the customer's current status.
• Administrators can still choose the method when creating orders manually in the dashboard.

Emails and thank-you page

The instructions text and the invoice terms are appended to customer emails and shown on the thank-you page. Admin emails are untouched.

Privacy

The plugin registers a personal-data exporter and eraser for the approval metadata. Order snapshots are retained under the store's normal order-retention rules.

Developer hooks

• goup_acig_is_customer_approved( bool $approved, int $user_id ) — override the approval decision.
• goup_acig_gateway_is_available( bool $available, int $user_id ) — final say on eligibility.
• goup_acig_customer_terms( string $terms, int $user_id ) — customer-specific terms.
• goup_acig_invoice_order_status( string $status, WC_Order $order ) — status after checkout.
• goup_acig_invoice_instructions( string $text, WC_Order $order, string $context ) — thankyou or email.
• goup_acig_order_snapshot_data( array $meta, WC_Order $order, int $user_id ) — extra _goup_invoice_* meta.
• Actions: goup_acig_customer_approved, goup_acig_customer_revoked, goup_acig_approval_updated.

Troubleshooting

• Approved customer cannot see the method — confirm the gateway is enabled under Payments, the customer is logged in, and no other plugin filters woocommerce_available_payment_gateways after this one. Enable Debug logging in the gateway settings and read WooCommerce → Status → Logs → goup-approved-customer-invoice-gateway.
• Diagnostics: WooCommerce → Invoice Diagnostics lists environment details and approved-customer counts to include in support tickets.

Updates and licensing

• Updates arrive through the normal Dashboard → Updates and Plugins screens. Every package is downloaded over a signed, time-limited link and verified against its SHA-256 checksum before WordPress installs it.
• View details on the Plugins screen shows the changelog for the new version.
• If the license is not active you still see that an update exists; the row explains that renewing restores one-click updates.
• The license page shows the installed version, the environment this site was classified as (production or staging), your activation counts and the renewal date, and has a Check for updates button.
• Deactivate on this site frees the seat so the key can be used on another site. Deleting the plugin from the Plugins screen also frees the seat automatically.
• Nothing is sent to goupwp.com except the license key, an installation ID, the site URL and the WordPress, PHP and plugin versions used for compatibility checks.

Support and maintenance

• Open a ticket from Account → Support on goupwp.com; include the output of the plugin's Diagnostics tab.
• Keep WordPress, WooCommerce and the plugin updated and test changes on a staging site first.
• The plugin declares compatibility with WooCommerce High-Performance Order Storage (HPOS) and the Cart and Checkout Blocks, and is translation-ready (languages/).
• Uninstalling removes the plugin's data only when the Delete data on uninstall option is enabled, so a reinstall keeps your configuration; license data is always removed.
