Bigcapital is turning its accounting core into an API product, then going quiet
Bigcapital is a self-hosted accounting suite shipping on a steady 0.25.x line. The spring releases built out a generated TypeScript SDK from an OpenAPI spec, wrapping banking, credit notes, reports, Payment Links, Stripe and Plaid into typed client modules. Since then the work has narrowed to correctness: base-currency handling in financial reports, localized column headers in CSV/XLSX/PDF exports, pagination, and form-state bugs in the web app.
Moov is filling in the payfac feature matrix, and now moves money on both US instant rails.
Moov ships every two to three weeks against a quarterly versioned API, with previews running ahead of each stable release. The recent work splits cleanly: acquiring features that merchants ask for by name — Google Pay, tipping presets, HSA/FSA/HRA card processing, credit card surcharging, user-defined amounts on payment links — and platform plumbing for the businesses embedding Moov, including resumable onboarding Drops, resolution links for failed verification, custom Dashboard roles, account connections with scoped visibility, and a client-side TypeScript SDK.

The SDK is the structural change here — an app that was edited through its own UI now has a published client surface, and later fixes explicitly reference "after SDK migration," meaning the web app is being rebuilt on top of the same contract external consumers get. Recent entries are dominated by report accuracy and export fidelity, the work that decides whether an open-source ledger is trusted for real books. Cadence has thinned since June.
Expect the SDK surface to keep absorbing modules the web app still calls directly, with the payments integrations (Stripe, Plaid, Payment Links) the most likely next area to get first-class documentation or a hosted counterpart.

Two arcs are running in parallel. The first is coverage: Moov is closing the gap on the payment methods and fee mechanics an established processor is expected to support, one release at a time, and instant payouts now reach both RTP and FedNow with the network chosen automatically. The second is that Moov is behaving less like an API and more like a platform its customers resell — connected accounts with scoped access, embeddable onboarding a merchant can resume and edit, fee-plan disclosure inside that flow. The API discipline underneath is unusually visible, with deprecations like taxAmount announced against a named version rather than dropped.
The v2026.10.00 preview is already published, so expect it to stabilize in the autumn window and carry more of the amountDetails consolidation that started with tax and surcharge fees. Given FedNow eligibility is now checked at bank-link time, more work on instant-rail routing and its failure modes is the likeliest follow-on.
