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 brings custom invoice templates and moves migrations off web requests.
SolidInvoice, the self-hosted invoicing app, shipped 3.1.0, 3.1.1 and 3.1.2 together on 29 October. 3.1.0 adds custom invoice templates and invitation expiry; 3.1.2 fixes the in-app upgrade path by running migrations at startup or as a Helm pre-upgrade job. It follows the 3.0 release in June that brought 2FA, OAuth and Meilisearch search.

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 brings custom invoice templates and moves migrations off web requests.
◆ Current state
SolidInvoice, the self-hosted invoicing app, shipped 3.1.0, 3.1.1 and 3.1.2 together on 29 October. 3.1.0 adds custom invoice templates and invitation expiry; 3.1.2 fixes the in-app upgrade path by running migrations at startup or as a Helm pre-upgrade job. It follows the 3.0 release in June that brought 2FA, OAuth and Meilisearch search.
◆ Where it's heading
After 3.0's identity and platform work, 3.1 turns to customization and operations, with Helm-based deployment now a supported path. Fixes are tagged with detailed commit-level notes, some co-authored with Claude.
◆ Prediction
Expect more 3.1.x fixes around upgrades and deployment, given two fix releases shipped alongside 3.1.0.
