How to Send WhatsApp Invoices in Nigeria (2026 Guide)
WhatsApp is the dominant business channel in Nigeria. Here's how to send polished invoices on WhatsApp that actually get paid — covering Paystack, Naira formatting, FIRS VAT, and auto-reminders.
If you run a business in Nigeria, you already know: WhatsApp is where deals close. Email feels formal. SMS gets ignored. But a WhatsApp message? Read in under 90 seconds, on average. The trick is making sure what you send through that channel looks as professional as the work you do.
This guide walks through exactly how to send a polished invoice on WhatsApp in 2026 — covering the legal essentials (FIRS VAT, TIN), the practical setup (Paystack vs bank transfer), and the automation that turns chasing payments from a daily chore into a one-time setup.
Why WhatsApp invoices work in Nigeria
Nigeria has over 90 million WhatsApp users. For most service businesses — agencies, consultancies, retailers, freelancers — the buyer-seller conversation is already happening there. Forcing a client back to email creates friction at the exact moment you want zero friction: the moment you ask to be paid.
- WhatsApp messages have a 98% open rate vs ~22% for email.
- Clients can tap the payment link and pay in under 30 seconds.
- You see the "read" tick — no guessing whether the invoice was received.
Step 1: What every Nigerian invoice must include
Before you worry about WhatsApp, get the document right. The Federal Inland Revenue Service (FIRS) and the 2020 CAMA Act require:
- Your business name and address as registered with CAC.
- FIRS TIN if your business is tax-registered.
- Invoice number (sequential — INV-0001, INV-0002, etc.) and issue date.
- Itemised line items with quantity, unit price, and line total.
- VAT at 7.5% if you are VAT-registered, shown as a separate line.
- Payment instructions — bank account details or a Paystack/Flutterwave link.
- Due date — typically Net 7 or Net 14 for Nigerian SMBs.
ereQa handles all of this in the free invoice generator — fill the form once and your business profile is reused across every invoice.
Step 2: Generate the invoice + payment link
You have two paths in Nigeria:
Option A: Bank transfer (simplest)
The invoice PDF includes your bank account number, name, and bank — your client transfers via mobile banking and sends a screenshot. Cost: zero. Downside: you mark the invoice as paid manually after the transfer hits.
Option B: Paystack or Flutterwave link (frictionless)
The invoice contains a payment link. Your client taps it, pays with card / bank transfer / USSD, and ereQa automatically marks the invoice as paid. Cost: 1.5% + ₦100 per transaction (capped at ₦2,000). Worth it if your invoice value is over ₦20,000 because of the speed and the auto-reconciliation.
Step 3: Send on WhatsApp in one tap
With ereQa, every invoice has a "Share on WhatsApp" button. Tap it, and a pre-written message opens with:
Hi Tunde, here's your invoice for the August content retainer (₦450,000 + VAT). You can view and pay here: ereqa.com/i/abc123. Thanks!
The link opens a branded payment portal — your logo, your business name, your bank/Paystack details. Your client never has to download an app or sign up for anything.
Step 4: Let automation chase the payment
The biggest mistake Nigerian SMBs make? Manually chasing. It takes time, it's emotionally draining, and it strains client relationships. Set up automatic reminders once and forget it:
- 3 days before due — gentle nudge.
- On the due date — friendly "your invoice is due today".
- 7 days overdue — firmer "this invoice is now past due".
ereQa sends each reminder as a WhatsApp-ready message you can review before sending, or fully automated if you trust the wording. Businesses that automate reminders see average payment time drop from 28 days to 11 days.
Real example: an Abuja design agency
A 4-person design agency in Abuja used to send invoices via email. Average payment time: 32 days. Their account manager spent 6 hours a week chasing. After switching to WhatsApp invoicing with auto-reminders:
- Average payment time dropped to 9 days.
- Account manager reclaimed 5 of those 6 hours per week.
- Client complaints about "I didn't get the invoice" disappeared.

Frequently Asked Questions
Can I legally send invoices via WhatsApp in Nigeria?
Yes. Nigeria's 2020 Companies and Allied Matters Act and FIRS guidance both recognise electronic documents — including PDF invoices and payment links — as legitimate. The invoice must include your business name, FIRS TIN (if registered), itemised charges, applicable VAT, and bank/payment instructions.
How do I include FIRS VAT on a WhatsApp invoice?
Add a line item showing 7.5% VAT calculated on the taxable subtotal. ereQa does this automatically — you just toggle "Apply VAT" when creating the invoice. Your TIN and VAT registration number are pre-filled from your business profile.
Will my client need a smartphone or app to pay?
No. The WhatsApp message contains a link that opens a public payment portal in any browser. Your client sees the invoice and your bank/Paystack details, then pays directly. They do not need an ereQa account.
Can ereQa send WhatsApp reminders automatically?
Yes — for invoices created in ereQa, you can enable automatic reminders 3 days before due, on due date, and 7 days after. Each reminder regenerates the same WhatsApp link with the latest balance.
