TL;DR
- Past orders are safe — personalization on historical orders lives in Shopify line item properties, not the app.
- Nothing auto-transfers between personalizers; you rebuild fields, fonts, options, and pricing (faster than it sounds).
- Parallel-run: keep Customily installed, rebuild + test in PIMW, switch product by product, then uninstall.
- Same POD vendors: PIMW is vendor-agnostic via standard line item properties — your Printful/Printify/Gelato setup is untouched.
- Why switch: flat pricing + free plan, no per-order transaction fees, native Cart Transform add-on pricing. Verify current pricing on each app's listing.
Why stores switch from Customily
Customily is a capable, mature personalizer with a deep template library — many stores are happy on it. The usual reasons to switch come down to cost structure and fit. Some Customily plans include usage- or order-based fees that grow with sales, so stores scaling up sometimes prefer flat, predictable pricing. Print It My Way uses flat monthly pricing with a free plan and no per-order transaction fees, so your software cost doesn't rise as orders increase. Others switch for native Shopify Cart Transform add-on pricing (each upgrade as a clean cart line item) or a lighter, vendor-agnostic personalizer. The decision should come down to your pricing tolerance and feature needs — see the full PIMW vs Customily comparison, and always confirm each app's current pricing on its Shopify App Store listing.
What's safe, what migrates, what's rebuilt
| Item | What happens |
|---|---|
| Past orders & their personalization | Safe — stored as Shopify line item properties on the order record |
| Your Shopify products | Untouched — they're Shopify objects, not app data |
| POD vendor connections (Printful/Printify/Gelato) | Untouched — PIMW uses the same line-item-properties mechanism |
| Personalization fields, fonts, options, templates | Rebuilt in PIMW (no auto-transfer between apps) |
| Add-on / upcharge pricing | Rebuilt in PIMW via Cart Transform |
Nothing transfers automatically between personalizer apps because each stores its product configuration in a proprietary format — there's no shared import/export standard. Rebuilding is faster than it sounds: you're recreating a known setup, not designing from scratch. Document your current Customily config (screenshots of each product's fields, options, and pricing) before you start.
The parallel-run migration (no downtime)
- Document your current Customily setup — screenshot each personalized product's fields, fonts, options, conditional logic, and pricing.
- Install Print It My Way alongside Customily — don't uninstall yet.
- Rebuild on a test product in PIMW — text fields, photo upload, options, live preview — and set add-on pricing with Cart Transform.
- Place draft/test orders and confirm the personalization reaches your POD vendor via line item properties.
- Roll out product by product, starting with best-sellers, swapping each from Customily to PIMW once verified.
- Uninstall Customily only when all live products are migrated and tested — removing its theme/product integration last.
Keeping both apps installed during the rollout means no product is ever without a working personalizer, and you can revert instantly if needed. See the general switch a Shopify personalizer app guide for the full checklist.

Why do stores switch from Customily to Print It My Way?
The most common reasons are cost structure and fit. Customily is a capable, mature personalizer, but some of its plans include usage- or order-based fees that grow with your sales, so stores scaling up sometimes look for flat, predictable pricing. Print It My Way uses flat monthly pricing with a free plan and no per-order transaction fees, so your software cost doesn't rise as orders increase. Beyond cost, some stores switch for a simpler setup, native Cart Transform add-on pricing, or a lighter, vendor-agnostic personalizer. Customily remains a strong choice — especially for its template library — so decide based on your pricing tolerance and feature needs, and always compare each app's current pricing on its Shopify App Store listing.
Will I lose my existing orders if I switch from Customily?
No. Past orders live in Shopify, not the personalizer app — the customer's personalization on historical orders is stored as Shopify line item properties on those order records, so it stays intact and viewable after you uninstall Customily or install a new app. What you rebuild is the personalization setup on your live products (fields, fonts, options, templates), because each app stores product configuration in its own system with no automatic transfer. The safe approach: keep Customily installed while you rebuild and test in PIMW, then switch over, so no live product is ever without a working personalizer. Back up anything you can export first, and verify a few past orders display correctly before uninstalling.
What transfers automatically and what has to be rebuilt?
Nothing transfers automatically between personalizer apps, because each stores product configuration and templates in its own proprietary format. You rebuild the personalization fields per product (text inputs, fonts, colors, photo upload, dropdowns), the design/print-area mapping, conditional logic, and add-on pricing. You don't lose your Shopify products, your POD vendor connections, or the personalization data on past orders (held as line item properties). Rebuilding is faster than it sounds because you're recreating a known setup — most stores migrate key products in an afternoon and the long tail over a week. Document your current Customily configuration (screenshots of each product's fields and pricing) before starting so you can replicate it exactly.
What is the step-by-step process to switch from Customily to PIMW?
Use a parallel-run migration so your store is never down: (1) Document your current Customily setup — screenshot each product's fields, fonts, options, logic, and pricing. (2) Install Print It My Way alongside Customily. (3) Rebuild the personalization on a test product in PIMW and set add-on pricing with Cart Transform. (4) Place draft/test orders and confirm the data reaches your POD vendor via line item properties. (5) Roll out product by product, starting with best-sellers. (6) Remove Customily's theme/product integration and uninstall it only when all live products are migrated and tested. Keeping both apps installed during rollout means no downtime and instant rollback if needed.
Does Print It My Way work with the same POD vendors as Customily?
Yes. PIMW is vendor-agnostic and works with any POD vendor through Shopify's standard line item properties — the same mechanism Customily uses to pass choices to fulfillment. Your existing Printful, Printify, Gelato, or other connections keep working; you keep your POD setup and only change the personalization layer. The customer's text, photos, and options are captured by PIMW and saved to the order as line item properties, which your vendor reads to generate the print file. Because the transport is Shopify-standard rather than app-specific, switching the personalizer doesn't disrupt fulfillment, and one setup works across multiple vendors.
How long does switching from Customily take?
For most stores, the core migration takes an afternoon to a few days, depending on how many personalized products you run and how complex each is. A handful of products can be rebuilt and tested in one session; dozens of personalized SKUs warrant a phased rollout over about a week, best-sellers first. The parallel-run approach means no downtime and no rush — you move products over as you verify each, and only uninstall Customily once everything is live and tested in PIMW. The time goes into recreating your field/font/option/pricing setup (which you'll have documented) and placing test orders to confirm data flows to your POD vendor, not on any technical data migration.
