Refill / circular model, how do Blueland refill subs and Loop returnable containers work on Magento?

Two distinct patterns:

Blueland-style refill subscriptions, customer buys the initial SKU (reusable bottle + first capsule) once, then auto-ships refill SKU (capsule only) every 4/8/12 weeks. The SKU swap is the key piece: Magento subscription engine (Adobe Subscriptions, Bold Subscriptions, or Mirasvit) needs to know that the second shipment is a different SKU at a different price than the first. Adobe Subscriptions handles this cleanly via subscription-template SKU sequencing. Bold needs a custom upgrade-path script. Mirasvit needs a product-link extension.

Loop-style returnable containers, customer pays a deposit at checkout (e.g. $5/container), keeps the product, returns the empty container, deposit refunded as store credit. The accounting piece is the hard part: Magento needs a deposit ledger tracking each container by serial number (or batch ID), the customer who has it, and the return SLA. Reconciliation runs via warehouse-scan webhook to Magento store-credit module.

Either way, expect 5-9 weeks of build time for a clean implementation. The subscription engine is the easy part; the customer self-service portal (skip refill, change cadence, swap variant, pause for travel) is what eats the timeline. Plan for it, mission-led customers churn fast if they can’t self-serve.
