Candis collapses approval-workflow sprawl — dynamic approvers and mandatory step fields land alongside an editor revamp.
The centerpiece of this window is a five-part Workflows release: a redesigned workflow editor, configurable mandatory fields per approval step, dynamic-field approver resolution (the right approver is picked from the receipt data — cost-center owner, project owner, invoice recipient), custom step labels, and the ability to import a workflow from another organization. Around that, Candis added Visa Click to Pay, a new layout and attachment support for Auslagen/Reisekosten (expenses and travel), an upcoming streamlined document layout (in beta from June 15), and improved automatching between credit-card transactions and invoices.
Kill Bill keeps hardening invoice reliability on its mature 0.24 line
Kill Bill is in steady maintenance on the 0.24.x branch. Recent releases concentrate on invoice-failure handling — retries, account parking, and uniform WARN logging — plus catalog and subscription edge-case fixes. This is reliability work on a mature open-source billing core.

Candis is reducing the number of workflow templates a finance team has to maintain — dynamic approver resolution and mandatory-fields-per-step replace what used to be a copy-paste workflow per cost center. The expense/document side gets steady UX polish on a separate cadence. Together it reads as a product moving from configurable-but-fiddly AP toward an opinionated AP backbone for German mid-market finance.
Expect dynamic-field resolution to widen beyond approvers — likely to account assignment and cost-center splits — and the upcoming document-layout beta to roll out as the default in late June. The cross-org workflow import has the shape of a future template marketplace if Candis chooses to lean into it.

The arc is operational robustness rather than new features: making invoice processing fail predictably, tightening lock-failure retries, and improving observability. A platform whose users run it as critical billing infrastructure rewards exactly this.
Expect continued 0.24.x point releases focused on invoicing/catalog correctness and logging, with no major architectural shift in the near term.
