TaxLane

Nigeria PAYE, VAT, Presumptive Tax, CIT eligibility, Withholding Tax, bulk payroll, Employer Cost of Employment, Capital Gains Tax & Stamp Duty, calculated in seconds.

Are these numbers accurate for 2026?

Yes — PAYE bands, VAT and CIT thresholds are built for the 2025 Tax Act, effective 2026. Estimates only, not tax advice.

Does my data really stay on my device?

Yes. Every calculation runs in your browser's JavaScript — nothing is sent to a server, logged, or stored.

Is TaxLane affiliated with the Nigeria Revenue Service (NRS) or the government?

No. TaxLane is an independent tool built by Quine Works — not a Nigeria Revenue Service (NRS, formerly FIRS) or other government product.

Try it — enter your monthly income.

PouchBooks

Log a sale, watch your stock update automatically, track who owes you, and send a proper receipt — for shop and kiosk owners, on web, Android, Windows, or Linux.

Is my sales and stock data safe?

Yes. PouchBooks works fully offline, on your device, by default — nothing is sent anywhere unless you turn on optional cloud sync from the app's Account tab.

Do I need an account or an internet connection?

No. Open it and start logging sales — no signup required. An account is only needed if you choose to turn on sync across devices.

Is PouchBooks really free?

Yes — PouchBooks is free software for shop and kiosk owners, no pricing tier or upsell.

The receipt a customer actually gets.
