Stigg
Stigg brings contract management and overages GA — usage-based billing gets enterprise contract depth.
A side-by-side editorial comparison of Invoice Ninja and Purchasely — release velocity, themes, recent moves, and the top alternatives to consider.
Invoice Ninja patches Square SCA, improves ACH handling, and extends bulk actions across all entities
Invoice Ninja is in active maintenance mode across its v5.13.x branch: payment gateway reliability (Square, PayPal, ACH) is getting sustained attention, with Strong Customer Authentication edge cases and token storage for offline payments being addressed. Bulk actions now span all entity types, and webhooks have moved back to queues with improved logging — signs of a maturing multi-tenant deployment model.
Purchasely 6.0 overhauls the SDK's core — initialization, presentation, and purchase flow get a full rewrite.
Purchasely is an SDK for managing in-app subscriptions and paywalls on iOS, Android, and web. SDK 6.0 modernized the initialization model, screen presentation, action handling, and purchase flow control across all platforms — a major version that breaks backwards compatibility but aligns the SDK with current platform requirements. SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.

The product is solidifying its payment gateway layer rather than adding new gateway categories. The addition of inline images for PDF generation, JSON design previews, and configurable document visibility suggest steady UX refinement in the invoicing and document workflow. No architectural pivots visible — this is a product in reliable incremental improvement mode.
The current trajectory points toward continued payment reliability work, particularly around SCA compliance, as European payment regulations tighten. Bulk action expansion may extend to custom entity types in future releases.

SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.
The 5.x series added screen orchestration (Flows), conditional visibility (Bring Your Own Screen), web checkout parity, and campaign tooling. The 6.0 reset cleans up the resulting complexity. The web-to-app redemption feature in 6.1 extends the funnel across platforms — subscribers who start on the web can redeem in the app and vice versa. This is a meaningful cross-platform monetization capability.
The next move is likely expanding web-to-app funnel analytics and deepening the server-to-server event model to support more complex subscription lifecycle scenarios (pauses, downgrades, family plans). The proxy routing feature in 6.1 suggests Purchasely is serving markets or enterprise environments with restricted network access.
