Sample data

An invoice shouldn’t live in four places.

Today one invoice is a PDF in a chat, a row in a spreadsheet, an alert from the bank and a phone call nobody wants to make. None of them agree on whether it’s been paid.

One record for every invoice. From first draft to final payment.

Every invoice now needs a reference the NRS recognises.

Under NRS e‑invoicing, business invoices carry an Invoice Reference Number, a digital signature and a QR code, and are transmitted to the Nigeria Revenue Service. Vendex adds all of it when the invoice is created.

Your receivables at a glance.

Paid, pending and overdue totals move as payments are matched, not when someone remembers to update a sheet. Expected cash for the next 30, 60 and 90 days comes from due dates and how each customer usually pays.

Know who to call first.

Every customer gets a risk score from their payment history, average days to pay and what’s still overdue, so you chase the right people.

Every action leaves evidence.

Who created the invoice, what changed, when it was sent, transmitted and paid. One record your accountant, auditor or customer can follow.

  • Owner, Manager and Finance roles decide who can send invoices and record payments
  • Credit and debit notes stay linked to the invoice they correct
  • Compliance reports: VAT returns, transmission log, tax summary
  • Two-factor sign-in and session controls on every account

You pay per invoice sent. Nothing monthly.

Questions, answered.

What is an invoice credit?

One credit is one invoice sent. Receiving payments, sending reminders and using your dashboard don’t use credits.

Do I need a subscription?

No. You get 3 free credits every month and can buy more in bundles when you need them. Nothing auto-renews and you aren’t locked in.

Do I need e-invoicing set up before I start?

No. You can create, send and track invoices straight away. Connecting to NRS e-invoicing is a separate step, and you can test it in the sandbox first. Read how it works.

How does payment tracking work?

With automatic payment collection on, a payment made through the invoice link is matched to its invoice and a receipt goes out. It costs ₦500 per processed invoice.

Prefer not to? Put your bank details on the invoice and record payments yourself at no extra cost. Part-payments are tracked until the balance is cleared.

Can my customer pay without installing an app?

Yes. They open a link in any browser and pay by bank transfer, virtual account or card. They don’t need a Vendex account.

How long do credits last?

Credits you buy are valid for 12 months. The 3 free monthly credits reset each month and don’t carry over.
