Invoice Ninja vs InvoiceShelf: at a glance
What is Invoice Ninja?
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.
What is InvoiceShelf?
InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
Invoice Ninja vs InvoiceShelf: editorial side-by-side
Invoice Ninja
5.0FINANCE
Invoice Ninja patches Square SCA, improves ACH handling, and extends bulk actions across all entities
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
InvoiceShelf
6.3FINANCE
InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
◆ Current state
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
◆ Where it's heading
3.0 is turning InvoiceShelf from an invoice generator into a small-business accounting app: payables next to receivables, EU-compliant e-invoices, a module ecosystem, and native mobile apps. The pace suggests the team is finishing features before a beta rather than stabilizing.
◆ Prediction
Expect more alphas filling in accounting pieces and modules built on API 1.4/1.5, with the iOS app appearing on TestFlight; the entries don't show a beta date.
