What Capium Ltd does

Capium Limited is a privately-held UK cloud accountancy software company founded in 2013 and headquartered in London, serving UK-based accounting practices with an integrated, subscription-based platform. Its product architecture unifies seven core compliance modules — Accounting Suite, Corporation Tax, Accounts Production, Practice Management, Self Assessment, Payroll, and Bookkeeping — with optional modules (Charity Accounts, Time and Fees, Company Secretarial, MTD Software) and add-ons (Anti Money Laundering via Veriphy, Capium 365 mobile app, Capium Pay embedded payments). The platform is built on Microsoft Azure infrastructure and integrates open-banking feeds through TrueLayer under PSD2. Capium is an HMRC-approved supplier for Making Tax Digital for VAT, Income Tax, and Corporation Tax, and is recognised by Companies House for iXBRL-tagged accounts production.

The company operates a product-led growth motion complemented by inside-sales demos, offering a 7-day free trial, per-client subscription pricing starting from approximately £1 per client (annual contracts, unlimited staff licences), and usage-based add-ons for bank feeds (£1.50+) and SMS/storage. Go-to-market emphasises content marketing, webinars on BigMarker, industry events (Accountex, ICAEW, IAB), and partnerships with UK accounting bodies. Its customer base spans 2,500-3,000+ practices and 505,000+ end-clients across the UK, with over 1 million filings processed through HMRC and Companies House. The company has disclosed only two early-stage funding rounds totalling approximately $1.24M (2015 and 2017) and operates with 11-50 employees and a Capium India group entity, indicating a bootstrapped, capital-efficient operating model focused exclusively on the UK market.
