FastSpring shipped a Sessions v2 API for headless checkout — a real opening to Stripe and Paddle's territory.
FastSpring's standout March release is the new Sessions v2 API: a programmatic surface for creating, modifying, and updating checkout sessions before redirecting buyers, with localized payment-options retrieval. Around it, the Order Details page got a full redesign (license-fulfillment management, deactivated-key visibility, consolidated lifecycle panels), and monthly refinement digests track a steady drip of fixes — currency expansion (PEN, PHP, MYR, VND), Pix and UPI on Managed Subscriptions, accessibility tweaks on Stacked/Embedded Checkout. A January advisory flagged a coupon-API breaking change (1,000-item cap on inline codes array, effective Feb 23).
Zoho Billing is growing a checkout surface for one-off items, not just subscriptions.
The July window is split between reporting and payment collection. On reporting: Active Subscriptions by Country and by Product, plus a Payment Method Summary that surfaces cards nearing expiry. On collection: hosted payment pages for individual items, shareable as a URL, QR code, iframe or HTML button, and a redesigned single-page checkout template in early access with abandoned-cart recovery and saved checkout progress. Role-based access on the SKU field and bulk TDS import round it out.

FastSpring is repositioning from a hosted-checkout-and-merchant-of-record vendor toward a more API-driven platform that can compete on the headless ergonomics that have made Stripe, Paddle, and Lemon Squeezy attractive to developer-led SaaS. The Sessions v2 API is the structural piece; the localization expansions and payment-method coverage (Pix, UPI, NOK PayPal, etc.) signal continued investment in non-US international payments where FastSpring has historically out-localized US-based competitors.
Expect Sessions v2 to be followed by deeper webhook-based session lifecycle events and an Embedded Checkout SDK rebuilt on top of v2. The localization push should keep widening — likely adding more Latin American and Southeast Asian payment methods to match where SaaS revenue is growing fastest.

Two directions are visible. Reporting is being cut by dimensions a subscription business actually plans against — country, product, payment-method expiry — which is groundwork for retention and dunning work rather than accounting output. More significant is that Zoho Billing now collects money for a single item outside any subscription, records it, and raises the invoice, which puts it in reach of transactions it previously had no surface for.
Expect the redesigned checkout to leave early access for all organizations, and the item payment pages to gain the recovery and portal features the subscription checkout just received.
