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 3.1.3 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.

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 3.1.3 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.
