Eleven years counting the right things

Claudenia was founded in Victoria Island in 2014 by three ex-Big-Four senior managers who wanted to deliver partner-level accounting attention without partner-level invoices.

Our story

Built in Lagos, trusted across Nigeria

We started in a co-working office on Idejo Street with four laptops and one big idea: that Nigerian SMEs deserved a chartered accountant who would pick up the phone, explain things in plain English and stay accountable when FIRS came knocking.

Eleven years later we have grown to 64 specialists across three offices — Victoria Island, Abuja Maitama, and Port Harcourt GRA — but the original promise still holds. Every client has a named lead partner, every email gets a same-day reply, and every engagement starts with a scope letter that fixes the price.

Today we work with 1,240+ active clients ranging from two-person fintech founders to 800-employee manufacturers, supporting them with bookkeeping, tax, audit and CFO-level advice.

How we work

The four values our partners hire for

Accountable to a named partner

Every client is allocated to one of our seven equity partners. You never get bounced between juniors who do not know your file.

Fixed scope, fixed fee

Engagements start with a one-page scope letter and a single number. Out-of-scope work is quoted in writing before it starts — no surprise invoices.

FIRS-grade evidence

We document every entry as if a tax officer is reading it tomorrow. That discipline is why our clients survive FIRS, LIRS and FRC reviews with minimal adjustments.

Same-day response, weekday or weekend

Our SLA is two business hours during the week and a same-day reply on Saturdays. Average response time in 2025 has been 47 minutes.
