Most Shopify setup mistakes aren't noticed on day one; they surface after sales begin, as high transaction fees, missing invoice integrations, falling Google traffic or mismeasured ad performance. What these mistakes have in common is that fixing them later is far more expensive than setting things up correctly from the start. When opening a store in Turkey, payment infrastructure, e-invoicing, legal pages and tracking in particular need to be planned from the outset.
In this article we explain the 10 mistakes we at Byte encounter most often in setup and migration projects, what they cause and how to prevent them. If you'd like to check things step by step before opening your store, see our Shopify store launch checklist too.
1. Choosing a plan based only on the monthly fee
As Shopify Payments isn't available in Turkey, stores working with providers such as iyzico and PayTR pay an extra transaction fee of between 2% and 0.2% depending on the plan. If you stay on the Basic plan as revenue grows, this extra fee can easily exceed the cost of moving to a higher plan.
How to prevent it: calculate each plan's total cost (plan fee + extra transaction fee) based on your expected monthly revenue. Details in our Shopify Payments article.
2. Leaving payment and e-invoice integration until the end
Payment provider applications, virtual POS approval and e-invoice integrator setup can take days or even weeks. Starting them after the design is finished delays the launch.
How to prevent it: start the payment provider and e-invoice applications in the first week of the project. We cover tax and invoicing obligations in our tax and VAT article.
3. Leaving legal pages and consent processes incomplete
A distance sales contract, pre-contract information form, KVKK privacy notice, cookie policy, return terms and ETBİS registration are required for every store selling in Turkey. When these are missing, there's legal risk, and payment providers may not approve the application.
How to prevent it: prepare the legal texts with a lawyer and set up the required consent checkboxes at checkout. Our KVKK and ETBİS guide shows the way.
4. Not planning the product data structure from the start
If variants, metafields, collection logic and product tags aren't planned correctly from the start, filtering, marketplace and ERP integrations, and ad catalogues cause problems later. Reorganising hundreds of products afterwards takes a lot of time.
How to prevent it: before uploading products, decide which attributes will be variants and which metafields, and whether collections will be automated or manual.
5. Over-customising a ready-made theme
Adding lots of custom code to a ready-made theme to fit it to your brand leads to a bloated, slow store. Theme updates can also break these customisations.
How to prevent it: either use the ready-made theme with limited changes, or build a brand-specific design on a lightweight theme framework. We compare the options in our article on paid and free themes.
6. Forgetting redirects when migrating from another platform
When moving to Shopify from a platform such as Ticimax, ikas, IdeaSoft or WooCommerce, the URL structure changes. If old URLs aren't 301-redirected to the new addresses, Google rankings and backlink value are lost, and users land on 404 pages.
How to prevent it: before migrating, export all of the old site's URLs, map them to the new URLs and bulk-upload them to Shopify's URL redirects section. After launch, monitor 404 errors in Search Console.
7. Leaving tracking until after launch
If Google Analytics 4, Meta Pixel and conversion APIs, Google Ads conversion tracking and Consent Mode aren't set up and tested before launch, the first weeks' data will be missing or wrong. Ad algorithms also start their learning phase with incorrect data.
How to prevent it: verify your tracking setup alongside test orders. For consent management, see our Consent Mode v2 article.
8. Installing more apps than you need
Installing a separate app for every need increases monthly costs and slows the store down. Uninstalled apps sometimes leave code behind in the theme.
How to prevent it: before installing an app, check whether the theme or Shopify's built-in features can do the same job. Check whether apps you remove have left traces in the theme code.
9. Leaving domain and email settings incomplete
If the sender domain isn't authenticated and no DMARC record is added, order confirmation emails can land in spam or be sent from a shopifyemail.com address.
How to prevent it: authenticate your sender domain and add a DMARC record before launch. We explain the steps in our DMARC guide.
10. Going live without test orders
In stores launched without testing payments, shipping rate calculation, discount codes, stock deduction, invoice creation and notification emails with a real order flow, the first customers run into errors.
How to prevent it: create test orders with different payment methods, shipping zones and discount scenarios; check invoice and email flows end to end, then cancel and refund the test orders.
Frequently asked questions
How long does it take to set up a Shopify store?
A simple store can be set up in a few days. Projects involving custom design, ERP or marketplace integration, and migration from another platform usually take 4–8 weeks.
Can I set up Shopify myself?
For simple stores, yes. But for payment and e-invoice integration, platform migration, SEO redirects and tracking setup, working with an experienced team prevents costly mistakes later.
Will I lose my Google rankings during migration?
In migrations done with correct 301 redirects, preserved meta information and the same content structure, there's no lasting loss. Short-term fluctuations are normal.
