Done-for-you Double and Shopify connection

Shopify Double Integration, Set Up by Shopify Specialists

A Shopify Double integration could not be confirmed: our research found no product page called Double, only general guides to linking Shopify through Zapier, one suggesting inventory triggers to connect two stores. We ask which tool you mean and its vendor site, then scope, build, test and hand over, from $690.

  • Product and vendor confirmed
  • Documented route chosen
  • Data mapped and duplicates guarded
  • Test log and a recorded handover

Our track record

Over 450 Stores Built Since 2015. Here Is What That Means for Your Double Link.

A decade spent in hundreds of Shopify stores pays off in small decisions: which id to use as the key, when to retry, which side wins a conflict. Those decisions make a Shopify app integration steady and dependable.

Who this is for

Who Needs a Careful Shopify Double integration Build

Multi-system stores need a clear route before anything is built. These are the cases we handle.

You are a good fit if
  • Your store runs on Shopify
  • You have, or will open, a Double account
  • You want a fixed price and a written scope
  • You can share the access we ask for
  • Teams naming a tool we cannot find

    We confirm the vendor first.

  • Brands running two stores

    Zapier triggers can link stores.

  • Teams syncing stock

    Inventory changes can be mirrored.

  • Teams needing two-way sync

    Many scenarios allow it.

  • Teams worried about double messages

    Poor mapping repeats notifications.

  • Teams expecting an app

    We cannot confirm one.

Problems solved

Shopify Double Integration: Six Faults We Fix First

Unclear-tool projects fail on guesses and doubles. These are the six faults we avoid.

The problem

Guessed route

The outcome

Nothing syncs. We confirm the vendor.

The problem

Double messages

The outcome

Customers get repeats. We map events once.

The problem

Stock loops

The outcome

Two stores overwrite each other. We set one master.

The problem

Duplicate customers

The outcome

Buyers repeat. We match first.

The problem

Fields over-shared

The outcome

Privacy is at risk. We limit them.

The problem

No handover

The outcome

Setup is unwritten, so the next change starts from guesswork. We write down the triggers, fields and tests.

How We Wire Double to Your Store, Step by Step

An integration is simplest to judge when you can see it. The picture shows the pieces we build for Double: the records on each side, the status of every link and the log a person can read.

Process and timeline

From First Call to Live Sync: Our Shopify Double Integration Process

We follow the same six steps on every build, which is why the price can be fixed.

  1. 1

    Brief and scope

    First we find out what you sell, how your team uses Double and which events count. A quick look at your orders and orders tells us where to begin and what to avoid.

  2. 2

    Access and connection

    You approve narrow access to Shopify and Double, using the app's own permissions screen. We confirm the connection with a live read before building on it.

  3. 3

    Map and rule

    Order tags, customer tags, metafields and app data are matched across both tools, and we record who wins each conflict and how blanks are treated.

  4. 4

    Build in a copy

    We build against test data, not your live records, and show you the plan and a recorded run where it helps.

  5. 5

    Test on real cases

    We test a paid order, an app event and a product edit, plus refunds and edits, then compare the results with what Shopify shows.

  6. 6

    Go live and hand over

    After your approval we turn the flow on, follow the first live runs, then hand over notes, a diagram and a short recorded tour.

Inside every project

What Keeps Your Store and Double Data Safe

Careful beats fast when personal data is involved. These are the habits behind every build.

Failures raise a flag

A failed run alerts a named person with the order and the reason. Silence never means success.

A written definition of done

The flow counts as finished only when a paid order, an app event and a product edit all pass and are logged.

Plain scope, two revision rounds

The price is visible before you pay, and in-scope changes get two structured rounds, so small tweaks never turn into hourly bills.

Counts compared, not assumed

Every load ends with a count against the source, which catches gaps and doubles quickly.

Nothing sent without approval

Every customer-facing message is reviewed with you first, then switched on.

Build in a copy, never live

Everything is built and tested on test data, so your live orders and orders stay untouched until you approve.

Build Your Double Integration Package

Choose a package, tell us about your order volume, data direction and existing Double data, then pick a speed. The fixed price and delivery window update with each selection.


Choose your packageRequired

Each package covers more of Double. Every option below shows its own price and any extra days, so nothing is revealed after checkout.

The essentials: Double connected, one flow built to pass the order details to the next step, tested end to end.

  • Double connected using the app's own permissions screen
  • One trigger built: when an order is paid
  • Mapping for order tags, customer tags and metafields
  • Duplicate protection on every write
  • Checks on a paid order and an app event
  • Test log plus a recorded walkthrough

The core set: Double will pass the order details to the next step; record the action on the customer; update the linked settings, protected by filters and retries.

  • Everything in Single Workflow
  • Three triggers: an order is paid; a customer takes an action in the app; a product is edited
  • App data and custom fields added to the map
  • Tag, country and value filters
  • Failed runs retried, then reported
  • Checks on a paid order, an app event and a product edit

The full build: two-way sync, history, monitoring for two weeks and a runbook.

  • Everything in Core Workflows
  • Both-way sync with a winner for each field
  • A one-off catch-up of earlier orders
  • Two weeks of monitoring after go-live
  • Roles and permissions reviewed
  • A runbook your team can follow

Custom objects, unusual authentication, several Shopify stores feeding one Double account, high-volume stores above 10,000 orders a month, and builds that need your own servers are quoted separately at a fixed price.

What is your monthly order volume?Required

Volume decides how much load planning the build needs.

Which way should data flow?Required

Two-way sync needs conflict rules for every shared field.

Are there existing records in Double to deal with?Required

Existing data is matched to Shopify ids up front.

How soon do you need it live?Required

Standard follows the schedule your other choices set. Pay to move up the queue and go live sooner.

Optional extrasOptional

Each one begins switched off. Turn on what you need, watch the total, switch it back off.

Why Store Design Expert

Why Hire Us to Connect Double and Shopify

Templates cover the happy path. We cover the rest, and we put the result in writing.

Tested on your real cases

Your real scenarios are the test plan: a paid order, an app event and a product edit.

4.9+ from verified clients

The reviews here come from verified clients of Store Design Expert, so you can judge past projects before you pay.

Safety designed in

Every build includes retries, alerts, unique keys and narrow access; none are paid extras.

A price you can plan around

The calculator shows the price and extra days for every package and option. Double bills its own plan fees, so check its current pricing page.

Notes a colleague can follow

Our handover records what moves where and which settings were chosen, so a future developer will not have to guess.

We live inside Shopify

Orders, refunds, edits and metafields are daily work for us. That is a different skill from knowing the menus of Double.

What we need to get started

What to Prepare Before We Start Your Double Integration

Three things get the work moving: safe access, a few answers and a decision-maker. Here is the detail.

Approve a collaborator request

If the store is live, send us its address and approve our request. Ownership stays with you, our role is limited, and removal takes one click.

Starting from nothing? We build first

No store yet? We build it in our Partner account, connect Double there and transfer the whole store to you, so you choose a plan only at the end.

Or share a staff login

A staff login works if that is easier. We still recommend the collaborator route, since it can be revoked in one click and leaves no password in circulation.

Your Double access

Either create the Double account yourself and add us, or we open it with your email. You remain the owner, and we work through the app's own permissions screen.

Sample records

Tell us where typical records live, or send a handful from each system. Real examples beat assumptions.

A decision-maker

We need one person to approve the plan and the test, plus a rule for what wins when Double and Shopify clash.

Your Shopify owner password and card details never reach us. Changes are made in a copy, and we note every setting we touch.

FAQ

Questions About Double and Shopify Integration

Everything owners ask us before booking.

How much does Shopify Double integration cost?

Single Workflow costs $690, Core Workflows $1390 and Full Integration $2690. Order volume, data direction, existing Double data and add-ons change the total, and the calculator shows it before you pay. Most projects land between about $690 and $3770, with delivery from 3 to 16 working days.

How long does the Double integration take?

Single Workflow takes 3 to 6 working days, Core Workflows 6 to 10 and Full Integration 9 to 16. The usual variables are how much history you want loaded and how quickly you approve the test results. The Sooner and Fastest options shorten the schedule when a launch date is fixed.

Does Double integrate with Shopify?

We found no page for it. This also answers "shopify to double sync".

Can Zapier link two stores?

Yes with inventory triggers. You may also see it searched as "double shopify integration vendor confirm zapier two stores inventory duplicate messages"; the work is the same.

Is two-way sync possible?

In many scenarios. Searches like "shopify double charge" lead to the same build.

What do you need?

The vendor's site. People also search for "shopify double opt in"; this page covers that too.

Can you still help?

Yes once confirmed. The same job is behind "shopify double authentication".

What does it cost?

Fixed price from $690 plus tool fees. The same job is behind "shopify double currency".

Can you scope it?

Yes. This also answers "shopify double authentification".
