My website is - www.kliger.art
I will start soon to give the option to subscribe to clients that instead of paying one time that will pay small fee every month for 12 month and they will get the product.
I checked with Klarna -https://www.klarna.com/se/foretag/produkter/prenumerationsbetalningar/ but they don't do the checkout with shopify...
Open for good ideas.
I think the term you're looking for is Buy Now pay later, or pay in installment. You can consider using Afterpay, but they only have this app https://apps.shopify.com/afterpay-attract for US store only.
Another app is Installment Recurring Payments, which allows customers to pay in installment, it's integrated with Shopify checkout as well.
Hope you find this helpful
