Import subscriptions from another app

If you’re switching to RebillCart from another subscription app, this tutorial walks through moving your existing subscribers over without asking them to re-subscribe.

Available on the Pro plan. See Pricing & Plans. Background reading: Migration (CSV Import).

1. Export from your current app

Export your active subscriptions to CSV from wherever they currently live. At minimum you’ll want each row to include:

• The customer (email or Shopify customer ID)
• The product/variant
• Billing frequency
• Current price / discount
• Next billing date
• A stable external ID from the source system (used to prevent duplicate imports)

Exact column names vary by source app — the importer isn’t tied to one specific competitor’s export format.

2. Set up matching plans first

Before importing, make sure a RebillCart subscription plan exists for each frequency/discount combination your import will need. The importer maps each row to an existing plan — it won’t create new plans for you.

3. Run a dry run

1. Go to Subscriptions → Import.
2. Upload your CSV.
3. RebillCart validates every row without creating anything yet — you’ll see which rows will succeed and which have problems (unmatched product, invalid frequency, missing customer, etc.).
4. Fix your CSV and re-upload if there are errors, or proceed if the dry run looks clean.

4. Commit the import

1. Once the dry run is clean, click Import to commit.
2. RebillCart creates a real Shopify subscription contract for each row via Shopify’s own contract-creation API — these are genuine subscriptions, not a look-alike RebillCart-only record.
3. Re-running the same file is safe — imports are deduplicated on the combination of your store and each row’s external ID, so nothing gets created twice.

5. Verify

1. Spot-check a handful of imported subscriptions in Subscriptions — confirm frequency, price, and next billing date match the source.
2. Confirm the customer sees the subscription in their Manage subscriptions portal.
3. Let the first post-import billing cycle run and confirm it charges correctly before fully decommissioning your old subscription app.

Protected Customer Data approval (a Shopify-side review) is required before this can run against real customer data on a live store — development stores work without it while you’re testing the process.
