Accounting firm app: clients, filings and deadlines in Lagos 2026

The verdict in three sentences

An accounting firm app that alerts on every VAT and CIT deadline prevents client penalties and month-end crises. In 2026, the document-upload portal and automatic reminders cut penalties by 80 % and save the firm 15 hours a month. For 120 clients, the investment is around 2,200,000 FCFA, delivered in 9 weeks.

The deadline calendar, the firm's real product

Accounting risk comes not from the math but from a missed date. By centralizing tax deadlines per client and automatically chasing missing documents, the app turns the firm into a compliance control tower.

Kossi, an accountant, handles 120 clients. Before the app, about 10 clients a year faced an average late penalty of 150,000 FCFA, or 1,500,000 FCFA in penalties and unhappy clients. With automatic alerts, he cuts that by 80 %, letting only 2 cases slip, and recovers 15 hours a month. At a billed rate of 20,000 FCFA/hour, those hours are worth 300,000 FCFA/month — the 2,200,000 FCFA app pays for itself in about 7 months.

FAQ

Which deadlines does the app track?

VAT, corporate income tax, business licence and social contributions, with an early per-client reminder to cut penalties by about 80 % in 2026.

How much time does the firm save?
