One Step Order Form for WHMCS Module by Provonic

The Whole WHMCS Order on a Single Checkout Page

Provonic One Step Order Form is a WHMCS one page checkout that replaces the multi-step WHMCS cart with a single order page. It is a WHMCS order form template, a WHMCS cart template and an addon module in one. A one step checkout for WHMCS means fewer pages and a faster WHMCS checkout for hosting, VPS and domains.

The customer chooses a plan, a domain, addons and configurable options, enters billing details and pays on one page. A live order summary beside the form shows the price of every item as it changes. Every amount comes from WHMCS itself, so the summary is priced exactly as the invoice will be.

Product bundles, promotion codes, tax, setup fees and free domains appear as WHMCS calculates them, with the original price struck through. The one page order form handles domain registration, domain transfer, an existing domain or a subdomain, with live availability checks. Upgrade and downgrade orders sent to the cart open on the same checkout page, with the upgrade credit and the amount due.

Cart checks from your other WHMCS modules run on the page too, so a refused domain, product or upgrade shows a clear message before the order is placed. The order form takes its colours, fonts and shapes from your client area template: Six, Twenty-One, Nexus, Nexum and Lagom, in light and dark mode.

Changelog

v1.1.4 Released November 1st, 2026

Latest Version


  • Added support for other modules' cart checks, so their domain, subdomain, product and upgrade rules are shown clearly on the order form before the order is placed.
  • Added upgrades and downgrades to the order form, with the new plan, its credit and the amount due shown in the order summary.
  • Fixed a few display issues on the domain step and in dark mode, and the order form now ships its own icons for every template.

 

Previous Versions


v1.1.3 Released October 24th, 2026

View/hide detailed changelog

  • Improved the domain availability check: .ng, .gr and .es domains (including .com.ng, .com.gr and .com.es) are now checked with their registries' own lookups.
  • Domain searches now ignore a pasted "https://", "www." or page path.

 

v1.1.2 Released October 20th, 2026

View/hide detailed changelog

  • Fixed card payments with Stripe and Stripe Dynamic so they always charge the total shown on the page, including after the order is changed on the page and with a payment gateway fee.
  • Fixed the billing cycle shown in Choose Billing Cycle and in the order summary not always matching, on the first page load and after switching plans.
  • Fixed long configurable option names and other content running outside their sections; a row now holds fewer cards when they would be too narrow.
  • Improved the layout on tablets: the order summary sits below the form with the total kept at the top of the screen, as on phones.

 

v1.1.1 Released October 15th, 2026

View/hide detailed changelog

  • Added quantity and billing cycle controls to the order summary, and payment gateway logos beside each payment method.
  • Improved the order summary: promotion, bundle and special prices are shown against the original price, the total due today is shown in larger type, and the list scrolls while the total and Complete Order button stay in view.
  • Improved compatibility with the Six, Twenty-One, Nexus, Nexum and Lagom templates in light and dark mode (including Lagom's Futuristic style), and with Payment Gateway Fees, Free Trial and Email Verification Extended.
