01The problem

Paying a government bill means finding the right agency, the right service and the right reference, then trusting that the money reached the treasury. The portal had to cover federal agencies and FIRS alongside state authorities like FCT-IRS and Lagos, with part-payments, identity checks and complaints, for people who never log in.

02The approach

A Next.js portal where a payer searches for an agency or looks up a bill reference, verifies who they are with a NIN or a company RC number, and pays through Flutterwave checkout. Behind the scenes the app raises the charge in RevOps, attaches TSA metadata to the payment, reports it to RevOps and Remita once it settles, and handles part-payments and complaints.

03How it works

Step 01

Find the agency or bill

Search a federal or state agency, or paste a bill reference. The lookup routes by status: new, pending, part-paid or already paid.

Step 02

Verify the payer

Individuals verify with a NIN and companies with an RC number, each on its own validated form.

Step 03

Raise the charge

The app creates the charge in RevOps and attaches TSA metadata to the payment, so the money is traceable to the right account.

Step 04

Pay through Flutterwave

Card or bank transfer through Flutterwave checkout, finalised after payment, with the transaction ID passed on to Remita.

Step 05

Confirm, or raise a complaint

A status page with a downloadable receipt, and a complaint form with file upload for when something went wrong.

04Before and after

Before

Each agency's bills paid in a different place
Unclear whether a part-payment counted
No identity check for company bills
Payment problems handled off-platform

After

One lookup for federal and state bills
Clear status: new, pending, part-paid or paid
NIN and RC number checks in the payment form
Complaints with evidence, from the success page

05See it run

The home page: search any federal or state agency and pay, powered by Flutterwave — Look up any agency

A searchable grid of federal agencies — Federal agencies

Payment details for an individual, with the NIN field and a Corporate tab — Payer details, NIN or RC number

Flutterwave checkout confirming a completed payment — Paid through Flutterwave

06Proof it holds up

Part-payments are recognised in the lookup, and amounts are formatted in naira throughout.
Every payment carries TSA metadata and is reported to RevOps and Remita once it settles.
I moved data fetching to React Query, reorganised the code into feature modules, and led the June 2026 redesign of the service search.
