Moov's issuing and invoicing APIs fill out as platforms take over more of the payments work.
Moov ships on a versioned API train, with v2026.10.00 still in development. Since September it has added self-serve fixes for ACH authorization errors, a taxable flag in the product catalog, a spending card activity endpoint, invoice reminders and custom invoice numbers, and issuing simulation endpoints for test mode. The summer added FedNow, payout fees and fee plan reassignment.
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.

The summer added FedNow, payout fees and fee plan reassignment.
The direction is self-service for platforms that embed payments: fixing ACH errors without support, running card issuing in test mode, sending invoice reminders automatically. Fee mechanics still matter, but recent releases have widened issuing and invoicing. The API usually gets each capability first, with the Dashboard following.
Expect v2026.10.00 to leave development with the ACH self-serve and isTaxable changes, and the Dashboard to pick up more issuing views. The entries give no date for that release.

After the large 3.0 release in June, work has moved to hardening: upgrade paths, packaging (Snap, static PHP builds) and correctness in payments and reporting. The mention of MCP payments shows AI-agent access is already wired into billing, though the entries don't detail it.
Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
