Stigg
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
A side-by-side editorial comparison of DocuSign and InvoiceShelf — release velocity, themes, recent moves, and the top alternatives to consider.
DocuSign rebuilt eSignature with AI and is now targeting the full contract lifecycle.
DocuSign has fully reoriented around its Intelligent Agreement Management (IAM) platform, with a proprietary AI engine called Iris now powering both the signing experience and the contract review workflow. The January 2026 eSignature redesign was the most visible signal: AI automates document prep, assists signers in real time, and reduces manual steps at the moment of execution. The March 2026 AI-Assisted Review extension takes Iris further upstream into negotiation and redlining.
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.

The product is moving systematically up the contract lifecycle — from post-signature management (where IAM started) backward through signing and now into pre-signature negotiation. Each step adds another layer of Iris AI to replace human review work. The logical terminus is a fully AI-mediated agreement workflow where Iris handles generation, review, negotiation, and execution with humans in an approval role only.
DocuSign's next likely move is deeper integration between Iris and enterprise data sources (CRM, ERP) so that agreement insights flow directly into existing business systems — or an agentic negotiation mode where Iris proposes and marks up contract terms autonomously.

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.
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.
