In their own words
Alethia
Alethia is entity management software for private equity, funds and investment managers, keeping entity records, ownership, documents and compliance information together. Structure charts use entity and ownership records and export to PDF, PowerPoint or Excel. The deal pipeline tracks six stages and can create a draft holding entity at Heads of Terms. Its funds-flow workflow checks whether sources and uses reconcile; someone other than the preparer must approve release. Incoming KYC requests are divided into requirements with proposed answers and identified sources, and each answer needs human approval. Alethia records bank accounts, signatories and mandate controls, but does not move money or show live payments. Entities and key fields can be imported from CSV. Two-factor authentication is required for all users, and material changes enter an append-only audit trail. The free plan covers five managed entities. Registry is listed at £1,000 per year, billed yearly at £12,000, excluding VAT, with a 12-month commitment and 100 active entities included; additional entities cost £10/month each.
TaxCalc
TaxCalc is a UK accounting software platform for tax compliance, client management, and practice operations. Its products prepare personal, partnership, trust, and company tax returns, as well as statutory accounts. For Self Assessment, SimpleStep guides users through relevant sections, with an option to switch to HMRC-style forms. Calculations update in real time, and Check & Finish reviews a return before submission. Tax products submit directly to HMRC, while Accounts Production files statutory accounts to Companies House. Accounts Production can import year-end trial balances from Xero, QuickBooks, or FreeAgent and export journals and adjustments; integrations differ between products. TaxCalc supports self-employment and investment income, but does not include state filing. It runs on Linux, macOS, and Windows, with mobile access limited to the web. Pricing is paid, from £42, with a free trial and no free plan. TaxCalc says each licence includes unlimited weekday phone and email support from UK-based, accountancy-trained specialists.
