Early access A Shopify app for combined shipping

Combine orders into one shipment. No new order.

Your original orders stay as they are, and nothing is ever refunded or cancelled. Kombi holds the first order until the next one arrives, then copies the tracking from your label to both.

5 free merges every monthUnlimited merges, no per-merge fees

Illustration: order #1041 is held so it isn't packed yet. Order #1042 from the same customer and address arrives. One label is bought for the parcel, and the same tracking number is copied automatically to both original orders, which are both fulfilled.

The problem

Small habits that quietly cost you money

When a customer orders twice before you ship, the usual fixes either waste postage or replace their orders with a new one — and leave a mess in your admin.

Postage

Packed before the next order lands

The first order is already packed when the customer orders again. Now it's two parcels, two labels and twice the packing time — to the same doorstep.

Admin

Originals left behind

Apps that create a new merged order leave the original orders for you to archive, tag or fulfill by hand. Forget one and it can look unshipped.

Stock & sales

Stuck stock, channel refunds

Merchants report in public App Store reviews that leftover originals kept inventory "Committed" and that Meta cancelled or refunded orders still marked unfulfilled.

Time

Copying tracking by hand

Pasting one tracking number into several orders is tedious and easy to get wrong — and customers notice when their order shows no tracking.

How it works

Three steps. Your orders never change.

Kombi works with the orders you already have and the label tools you already use.

  1. Notify

    A second order comes in — you get a notification

    Kombi spots unfulfilled orders from the same customer going to the same address and lets you know they can ship together.

  2. Hold

    Review, click Merge — the orders are held

    Kombi places a fulfillment hold so the first order isn't packed and shipped on its own. On Unlimited, auto-merge does this for you. Undo is one click.

  3. Ship once

    Buy one label — tracking is copied automatically

    Buy the label as usual with Shopify Shipping, ShipStation or similar. Kombi copies that tracking number to the other orders. Nothing to type in.

Why Kombi

Combine shipping, keep the orders you already have

Some apps combine shipping by creating a new, merged order. Kombi keeps the originals and gives them one parcel and one tracking number.

  1. 1No new order. Your original orders stay as they are — same numbers, same revenue, same reports.
  2. 2Never refunds or cancels anything. Kombi doesn't edit orders either, and doesn't ask Shopify for permission to.
  3. 3Holds the first order so it isn't packed before the customer's next order arrives. You get a notification, review and click Merge — or turn on auto-merge with Unlimited.
  4. 4Tracking copied automatically from the label you already buy (Shopify Shipping, ShipStation and similar). Nothing typed in by hand.
  5. 5One-click undo before shipping, and an immutable audit log of every action.

Why it's safe

Built so it can't break your orders

Kombi never edits, cancels or refunds an order and never touches payments. It doesn't even ask Shopify for permission to.

No new order

Your originals stay the source of truth for revenue, reports, Meta and other channel orders, and loyalty apps like Smile.

Never edits, cancels or refunds

Kombi only places and releases its own fulfillment holds and fulfills orders with your tracking. Payments are never touched.

No permission to edit orders

Kombi never asks for permission to edit orders, so it simply can't change order contents.

One-click undo

Until the shipment is created, undo releases the hold and your orders are back to normal.

Immutable audit log

Every merge, undo and tracking copy is written to an append-only log. Nothing is silently rewritten.

Privacy by design

Addresses are compared using a keyed hash, access tokens are encrypted, and logs contain no customer personal data. GDPR webhooks supported.

New merged order vs. original orders

There are two ways to combine orders on Shopify. Some apps create a new merged order; others, like Kombi, keep the originals and give them one shared tracking number. Here's what changes in your store with each — using Mergify as the cited example of a merged-order app.

FAQ

Questions merchants ask before installing

Does Kombi create a new order?

No. Your original orders stay as they are. Kombi places a fulfillment hold on them so nothing ships separately, and when you buy a label for one of them, the same tracking number is added to every order in the group. There's no extra order to archive, tag or clean up.

Does Kombi ever refund, cancel or edit an order?

No. Kombi never asks Shopify for permission to edit orders, so it can't refund, cancel or change an order. It only places and releases its own fulfillment holds and fulfills the orders with tracking.

How does the hold work?

When a customer orders again before you've shipped, Kombi notifies you. Review the group and click Merge (or let auto-merge do it on Unlimited), and Kombi holds the orders so the first one isn't packed and shipped on its own. Undo releases the hold.

Do I have to type in the tracking number?

No. Buy the label as you already do — with Shopify Shipping, ShipStation or a similar tool — for one order in the group. Kombi copies that tracking number to the other orders automatically, so every original order is fulfilled with tracking.

Will my inventory, revenue and analytics stay correct?

Yes. Because Kombi never creates, edits, cancels or refunds orders, your order count, revenue and reports stay as they were. Inventory isn't left stuck as "Committed" on a leftover order, and loyalty points from apps like Smile keep working off the original orders.

What about orders from Facebook, Instagram and other channels?

They stay intact. Kombi doesn't change the order itself, and every original order is marked fulfilled with real tracking — so channel orders (for example from Meta) are not left sitting unfulfilled.

How does undo work?

Until the shipment is created, undo is one click: Kombi releases its hold and the orders go back to normal. Every action — merge, undo, tracking copied — is written to an append-only audit log you can review.

Does Kombi work with 3PLs and fulfillment services?

Not yet. Version 1 supports orders shipped from your own locations — for example when you buy labels with Shopify Shipping or ShipStation. Support for 3PLs and fulfillment services is planned for a later version.

Will my customers get extra emails from Kombi?

No. Kombi doesn't send any emails to your customers. It works quietly in your Shopify admin.

Does Kombi merge orders placed before I installed it?

No. Kombi tracks orders from the moment you install it onward. Older orders aren't backfilled.

What counts as a merge?

One merge is one group of orders combined into a single shipment — whether that group has two orders or five. Detecting mergeable orders, reviewing them and undoing a merge before shipping don't count; you only use a merge when you merge a group.

What happens when I reach the 5 free merges?

Nothing breaks and you are never charged extra. Kombi keeps detecting orders that can ship together and your Orders page keeps working; you'll simply be asked to upgrade to Unlimited before you can merge more that month. There are no per-merge fees.

Is there a free trial?

Yes. Unlimited comes with a 14-day free trial, and the Free plan includes 5 merges every month with no time limit. Billing runs through Shopify in USD every 30 days, and you can cancel anytime.

Ship together. Keep your original orders.
