Combine Invoices for Paymenter: one checkout for eligible renewals

Managing several services should not require repeating the same payment flow for every renewal. Combine Invoices adds a customer invoice selector and an admin bulk action to Paymenter, with a review step before a replacement invoice is created.

The downloadable package is now available for US$12.99 as a one-time purchase. INR catalog pricing is automatically converted from that USD source price. Check the product page for the current local amount and checkout for applicable taxes.

What customers can do

Customers select eligible unpaid renewal invoices in one currency, check their service names and amounts, then review one total. They pay the replacement invoice through Paymenter's existing checkout. The included services stay separate: this does not merge them into a new subscription or give them a shared renewal date.

What administrators can do

Staff can select invoices in the admin list and use the Combine invoices bulk action. The replacement records references to its originals. Before checkout or payment has started, the available undo action can restore the original arrangement.

Once a payment attempt exists, undo is blocked to keep previously created payment links from settling a different arrangement.

Know the eligibility rules

The invoices must belong to one customer, use the same currency and have compatible billing details. First orders, upgrades, credit deposits, preorders and invoices with prior payment attempts are excluded. Services with competing automatic payment arrangements also require separate handling.

Those checks are part of the feature. Combining invoices is a convenience for compatible renewals, not a way to bypass their payment history.

Installation and compatibility

The ZIP includes an installation README and the integration installer. Read the core-hook requirements and back up the installation before applying changes. Testing covers Paymenter 1.5.2 and PHP 8.3; custom themes and other versions need their own checks.
