DocuSign vs SolidInvoice: at a glance
What is DocuSign?
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.
What is SolidInvoice?
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.

DocuSign rebuilt eSignature with AI and is now targeting the full contract lifecycle.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
SolidInvoice
5.0FINANCE
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
