What is a Shopify Pre-Order?

A Shopify pre-order allows customers to purchase products before they're available or in stock. Pre-orders help merchants:

Capture demand for upcoming products
Continue selling when items are out of stock
Validate product ideas before manufacturing
Improve cash flow with advance payments

K1 PreOrder makes setting up pre-orders on Shopify simple — no coding required.

Why choose K1 as your Shopify Pre-Order Manager

We go all-in to cover every merchant need — from setup to scale

See Live Demo

Split payments with full control

Most apps: Partial payments are extremely limited and complicated to set up

K1 PreOrder: Set up split payments per product, collection, or variant, and show customers clear payment terms with dynamic messages

Instant Button Replacement

Most apps: Switching from "Add to Cart" to "Pre-order" button takes 1-2 seconds which confuses customers

K1 PreOrder: Almost instant replacement and removing "buy now" button - customers never see button switching

Rule system advantage

Most apps: One setting for all products

K1 PreOrder: Separate rules for different products, timeframes, texts, and conditions

Smart Cart Inventory Allocation

Most apps: When stock is low, customers can only buy what’s available - the rest of the demand is lost.

K1 PreOrder: When a customer adds more items than you have in stock, K1 automatically splits the cart — regular items for what’s available, pre-orders for the rest. One checkout. No lost demand. This split happens nowhere else. It’s exclusive to K1 Pre-Order.

Universal Placement

Most apps: Work on the product page and glitching on the collection page

K1 PreOrder: Pre-order badges and buttons appear on product pages, collections, quick view, featured sections, recommendations - everywhere

Founders Support

Most apps: Hired low-qualified support agents

K1 PreOrder: Real help from people who built it

Why K1 Pre-Order for out of stock products is the best

The complete feature list of right now

Partial Payments & Deposits

Flexible payment options that increase conversion and reduce checkout friction

  • Deposit payments - offer full payment, deposit, or split payments per rule
  • Clear payment terms - show what customers pay now vs. later with dynamic messaging
  • Visibility control - set the default option and reorder how payment options appear

Payment Options Widget

A clean storefront widget to explain payment choices and reduce customer questions

  • Display available payment options (full, split) right where customers decide
  • Show different payment details based on product or rule
  • Theme-matched design - looks native and stays consistent across your storefront

Display pre-order button anywhere

Universal pre-order integration that works everywhere your products appear

  • Seamlessly replaces Add to Cart buttons across product pages, collections, homepage, quick view, recommendations, and featured sections
  • Zero manual theme editing required - works instantly after installation
  • Perfect integration with any Shopify theme, old or new

Smart pre-order rules

Create unlimited rules with precision targeting for maximum control

  • Set different pre-order conditions for specific products, entire collections, or individual variants
  • Automatic conflict detection prevents overlapping rules and ensures smooth operations
  • Run multiple campaigns simultaneously without technical headaches

Custom Email Notifications

Branded, automated emails for every pre-order moment

  • Emails for every moment — order placed, balance due, overdue / payment failed, balance paid, item fulfilled, and cancelled / refunded
  • Timing & audience control — send before or after each event, targeted by rule, product, or order tags
  • Design & measure — drag-and-drop or HTML editor, dynamic variables and action buttons, test sends, and full open/click stats

Customer Accounts — Pre-order Self-Service

Let customers view and manage their own pre-orders — fewer support tickets

  • Self-service portal — a "My pre-orders" area inside Shopify Customer Accounts shows items, deposit paid, balance due, and status
  • Pay balance & update card — customers pay the balance early or update their saved card themselves, no support request needed
  • Self-service cancellation — customers cancel any pre-order before fulfillment, right from their account

Refund & Cancellation Policy

Decide exactly what customers can cancel and what gets refunded

  • Separate deposit & full-payment rules — set independent refund policies for deposit-only and fully-paid orders
  • Your own cancellation terms — shown before customers confirm, plus a message for orders that can no longer be cancelled
  • Apply on your terms — to new pre-orders only, or new + existing

Cart Price Display for Partial Payments

Show the deposit amount in the cart, not the full price

  • Two display modes — Full price (default) or Deposit only, so totals show exactly what the customer pays today
  • Less checkout confusion — ideal when a full-price line feels confusing after choosing a deposit option
  • Preview before you launch — the rule editor’s Cart preview follows the same setting

Fulfillment Automation

Automatically collect the balance the moment a pre-order is fulfilled

  • Auto-charge the balance — charges the saved payment method on Fulfilled
  • Mark as paid — flag as paid in Shopify without charging
  • Set once, app-wide — applies to every pre-order, no manual work

Pre-Order Limits

Cap how many units can be pre-ordered per product or variant for full control over demand

  • Set limits per rule — define the maximum pre-order units by variant or product, exactly where you need them
  • Automatic "Sold Out" — once the limit is reached, the pre-order button switches to a customizable Sold Out button, no overselling
  • Build scarcity — show remaining availability like "Only 5 left!" to create urgency and boost conversions

Offline Balance Collection

Take the deposit online, collect the balance offline

  • Deposit online, balance offline — settle the rest outside Shopify: in-store pickup, cash on delivery, wire transfer, or B2B invoice
  • Choose how the balance closes — auto-charge the saved card, or close it manually with Shopify’s "Mark as paid"
  • Built for B2B & made-to-order — ideal for high-ticket workflows where the final payment happens off-platform

Schedule rules

Time-based automation for perfect campaign timing

  • Launch pre-order campaigns at exact dates and times
  • Automatically end campaigns when products become available
  • Plan seasonal releases and limited drops weeks in advance

Stock control

Intelligent inventory triggers that adapt to your business needs

  • Always: Keep products on pre-order regardless of stock levels
  • Out of stock: Automatically switch to pre-order when inventory hits zero
  • Below threshold: Start pre-orders when stock drops to your specified level

Inventory autopilot

Smart on/off for "Continue selling" - no manual work

  • Auto-enables "Continue selling when out of stock" for pre-order variants
  • Restores original inventory settings as soon as the rule ends or stock recovers
  • Per-variant + schedule aware tracking keeps PDP/collections in sync and prevents oversells

Design Flexibility

Perfect visual integration with your brand identity

  • Shows dates in the right format for each customer’s storefront language
