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.
Shift4
5.0FINANCE
Shift4 Venue Q4-R2 is on canary venues now, with global release set for November 17.
◆ Current state
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R2 reached canary venues on 12 November with global release planned for 17 November, covering Quick Service POS, Menu Manager, the Status App and access tooling. Q4-R1 went global on 28 October, and Customer Hub 2026w45 headlined a Transactions Marketplace without describing it.
◆ Where it's heading
The venue suite moves in quarterly bundles split into two or three releases, each going canary first and global about a week later, with patch releases trailing. Customer Hub ships weekly and has been building enterprise-level menu controls for multi-location groups.
◆ Prediction
Expect the Q4-R2 global notes around 17 November and a Q4-R2 patch shortly after, following the Q3-R3 pattern. What the Transactions Marketplace does remains unclear from the feed.
