Overview

About This Project

Olowo brings everything a UK landlord, sole trader or small business owner juggles: bank apps, spreadsheets, accountant software, HMRC filings, invoicing tools and payment chases on WhatsApp, into one calm platform. Users see their full financial picture, manage properties, send invoices, track expenses and file taxes directly to HMRC without needing three different tools and an accountant on speed dial.

The Challenge

UK landlords and self-employed workers juggle multiple bank apps to see their money, track property income in spreadsheets, file Self Assessment and VAT manually through Gov.uk, and only discover their tax position at deadline season. Nothing talks to anything else.

Our Solution

We built Olowo as a unified financial operating system: Open Banking connections across UK and Nigerian banks, direct HMRC integration for Self Assessment, VAT and Corporation Tax, a full invoicing lifecycle, property portfolio tracking with compliance deadlines, and GBP-to-NGN remittances for the diaspora. AI-powered categorization keeps the books tidy automatically.

The Outcome

  • One platform replacing bank apps, spreadsheets and filing tools
  • Direct HMRC filing for individuals, landlords, companies and charities
  • Full financial visibility with consolidated balances and FX conversion
  • Free sandbox mode letting users try every feature before connecting real accounts
