Accounting Software That Speaks SaaS

AccountsOS is accounting software built for UK SaaS founders: Finn understands MRR, deferred revenue, and Stripe reconciliation natively, doing the books in the background so you can focus on shipping. £20/month, 14-day free trial.

Sound familiar?
Traditional accounting software that doesn't understand recurring revenue
No way to track MRR, ARR, or churn in your books
Deferred revenue handling that requires manual calculations
Annual subscription payments that skew your monthly P&L
There's a better way
AccountsOS gets SaaS. A £1,200 annual payment isn't £1,200 revenue in January; it's £100/month over 12 months. Finn understands that. Subscription tracking, deferred revenue handling, MRR visibility, and Stripe reconciliation, all built in. Finally, accounting that matches how you think about your business. £20/month, everything included.
Subscription revenue recognition done correctly
Deferred revenue tracking for annual plans
MRR and ARR visibility in your dashboard
Stripe and payment processor reconciliation
SaaS expense categories (hosting, tools, subscriptions)
Finn tracks churn impact on your books

I love the innovative approach to accounting
I love the innovative approach to accounting, which can often be quite dull. I particularly appreciate how interactive it is, including the emails, reminders, and the ability to anticipate the next step.
