The sequence

Seven steps. You can stop at any of the first six.

  1. Export your subscriptions CSV from Bold

    In the Bold Subscriptions admin, export your active subscriptions to CSV. You want customer email, products and variants, quantities, prices, billing frequency, next order date, and shipping address. Keep Bold running — it bills your customers normally until cutover.

  2. Upload the CSV to RefillKit

    Open the migration wizard and upload the file. The Bold preset maps Bold’s column names automatically, and every mapping can be adjusted by hand before anything else happens.

  3. Read the validation report

    Each row is checked before anything is created: malformed dates, products or variants that don’t exist in your Shopify catalog, missing emails, duplicate rows. Fix and re-upload, or exclude flagged rows and migrate the rest.

  4. Run the dry run

    See the exact contracts that would be created — products, prices, frequencies, and each customer’s preserved next billing date — without touching your store.

  5. Approve and execute

    Contracts are created paused, paced to stay inside Shopify’s API limits. A customer Bold would have billed on the 3rd stays on the 3rd.

  6. Activate, then wind down Bold

    Nothing bills until you activate. Once you do, cancel the matching subscriptions in Bold so nobody is billed twice. We can walk the cutover with you over email.

  7. Rollback window

    Until activation, one click removes everything the migration created. No charges were made, so there is nothing to unwind with customers.

Payment methods, honestly

Expect the card-update email flow. It’s automated.

This is the honest trade-off of leaving Bold, whichever app you move to. The practical play is to activate a few days before the bulk of your renewal dates, so customers have time to update their card before their first RefillKit charge — the validation report shows the renewal-date spread so you can pick that window deliberately.

Check your Bold export before you commit.

The free preflight check reads your Bold CSV and reports what would validate, what needs fixing, and how many customers would get the card-update email.
