FreeAgent vs SolidInvoice: at a glance
What is FreeAgent?
FreeAgent widens VAT and mobile MTD tools while pitching itself as accounting for every business.
FreeAgent's recent feed is filling in its compliance core. Over the summer it shipped quarterly Making Tax Digital submissions from mobile and seven VAT workflow improvements, and in October its Director of Product framed the roadmap as building FreeAgent for every business type, after June's Landlords product and the CIS simplification.
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.

FreeAgent
2.5FINANCE
FreeAgent widens VAT and mobile MTD tools while pitching itself as accounting for every business.
◆ Current state
FreeAgent's recent feed is filling in its compliance core. Over the summer it shipped quarterly Making Tax Digital submissions from mobile and seven VAT workflow improvements, and in October its Director of Product framed the roadmap as building FreeAgent for every business type, after June's Landlords product and the CIS simplification.
◆ Where it's heading
The pattern is segment-by-segment expansion (landlords, construction subcontractors) on top of a UK tax compliance base that keeps getting deeper. MTD for Income Tax is the anchor: each segment gets tooling for the filing obligations it now faces.
◆ Prediction
Posts are sparse and mostly retrospective, so timing is unclear; the next visible move is likely MTD for Income Tax readiness work ahead of its rollout, possibly another segment-specific product.
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.
