How to write a proper invoice in Mauritius

What a Mauritian invoice should show, how numbering and VAT lines work, and how to correct a mistake without breaking your records. A guide from Envoice.mu.

Picture a plumber in Curepipe who finishes a job, sends "Rs 3,500 for today, thanks" on WhatsApp and treats that message as the invoice. It works until the client pays Rs 2,000, goes quiet, and three weeks later nobody can say for certain what was agreed. A proper invoice exists to stop that conversation before it starts.

What an invoice is for

An invoice asks for payment, but it's also your evidence. It tells the client what they owe and by when, and it tells your accountant (and the MRA, if you're VAT-registered) what you sold. When the document is vague, each of those readers fills in the gaps their own way, and rarely in your favour.

The details every invoice should carry

Most invoices that cause trouble are missing something simple. Before you send one, make sure it shows:

  • your business name, address and BRN;
  • your VAT registration number, if you're registered;
  • the client's name and address, plus their BRN when the client is a business;
  • a unique invoice number and the date of issue;
  • a line for each item or service, with quantity, unit price and amount;
  • the total before VAT, the VAT amount and the total due;
  • the due date and how to pay, whether that's a bank account, a Juice number or cash at the counter.

If you're VAT-registered, the law fixes the list. According to the MRA's guidance, a VAT invoice must show:

  • the words "VAT INVOICE";
  • the seller's name, address, VAT number and BRN;
  • a serial number and date;
  • a description of the goods (with quantity) or of the services;
  • the value of the supply and its VAT treatment;
  • the VAT amount and rate;
  • the exchange rate for foreign-currency supplies.

When the buyer is a business, the invoice must also show the buyer's name, address and BRN, plus their VAT number if they're registered. Special identification rules apply when a private customer asks for an invoice in their own name (section 20 of the VAT Act), so ask your accountant how those rules touch your sales before you redesign your template.

Descriptions deserve more care than they usually get. "Works" tells nobody anything, whereas "Replace kitchen mixer tap, supply and fit, 1 unit" tells the client what they paid for and gives you something to point at if they argue.

Numbering: one sequence, no gaps

Give every invoice the next number in a single sequence and never reuse one. A skipped or duplicated number is the first thing an accountant asks about, because it can mean a lost sale or an invoice somebody quietly deleted. Paper books and Excel templates make this hard to police, since anyone can type any number into the box.

Adding VAT the right way

Show VAT on its own line instead of burying it inside one figure. At 15%, a Rs 10,000 job carries Rs 1,500 of VAT and the client owes Rs 11,500.

Some supplies are zero-rated and some are exempt. They look alike on an invoice but behave differently on your return, so mark each line correctly and ask your accountant when you aren't sure which applies. If you aren't registered, don't add VAT at all; if your turnover is getting close to Rs 3 million, read our article on VAT registration and talk to your accountant.

Mistakes: use a credit note, not the delete key

Wrong price, wrong client, wrong quantity? The tempting fix is to open the invoice and change it. Don't. Once an invoice has gone out, the clean way to correct it is a credit note that cancels all or part of it, followed by a new invoice if needed. Your records then show what happened and when.

Envoice enforces this. Issued invoices are locked, so a correction always goes through a credit note. Some owners find that strict in the first week, and then a client claims they were charged a different amount and the locked record settles it in a minute.

Send it, then keep the proof

Send the invoice the way your client actually reads things. In Mauritius that's often WhatsApp, so Envoice gives you a link you share by WhatsApp with a tap. It's a share link that you send yourself, not an automated WhatsApp message.

When money arrives, record it against the invoice. That can be the full amount or a part payment by Juice, cash, card, bank transfer or cheque, and Envoice issues a numbered receipt each time. The invoice then shows what's been paid and what's still owed, which is the whole point of the exercise.

If the job started with a quote, convert the quote into the invoice instead of retyping it. Quote, invoice, paid: one chain, with the same figures at every step.
