InvoiceShelf vs Purchasely: at a glance
What is InvoiceShelf?
InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.
What is Purchasely?
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.

InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
◆ Current state
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.
◆ Where it's heading
3.0 is turning a single-company invoicing app into something a hosting provider can run for many customers: role presets across companies, provider-controlled module installs, a separate customer-portal host and a locked-down container. The security fixes (guessable document links, SSRF through mail settings, a setup token that acted as super-admin) show the multi-tenant hardening is still catching up with the feature work.
◆ Prediction
Expect more alphas that close security issues and fill out hosted-provider controls before a beta; the entries show no beta date.
Purchasely
2.5FINANCE
Purchasely 6.0 overhauls the SDK's core — initialization, presentation, and purchase flow get a full rewrite.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
