Speed proof

Done talking? 2.6 seconds later, it’s sent.

Don’t take our word for it. Here is every run of our stopwatch test, how we measured it and how you can try it yourself.

The numbers

20 runs, one stopwatch.

The clock starts when the sentence is done and stops when Jiffy shows the invoice as sent. The middle run is the number on our site.

How we measured

A real sentence, a real invoice.

  1. One real sentence

    The sentence below goes into the assistant the way speech recognition hands it over. Saying it takes about 6.1 seconds; that part is not in these numbers.

  2. Start and stop

    The clock starts when the sentence is done and stops when the invoice shows as sent. The one tap you make to approve it is included.

  3. Really sent

    After every run we check that the invoice is no longer a draft and went to the client’s address. A draft doesn’t count.

  4. Every run counts

    We ran it 20 times in a row and show them all. We measure again after big changes, and this page follows.

Good to know

The small print, in plain words.

  1. Part of Ultra

    Speaking an invoice uses the AI assistant, which comes with Jiffy Ultra. Making one by hand works on every plan, Free too.

  2. You stay in control

    Jiffy shows the invoice and who gets it before anything goes out. Nothing is sent until you tap.

  3. Your setup matters

    Your connection and your phone add or save time. The setup above shows exactly what we used.

  4. One sentence is enough

    Say the client, the work and the price, then “and send it”. Jiffy takes the address and the rest from your client.

Try it yourself

Beat our time.

  1. 1. Open the assistant

    Tap the mic at the top of your Jiffy home screen, then the big mic.

  2. 2. Say it in one go

    “Invoice Harbour Café for two hours of design at 85 pounds an hour and send it.”

  3. 3. Check and tap

    Jiffy shows the invoice and who gets it. One tap and it’s on its way.

Questions

Good to know

Answers in a jiffy.

Why the middle run and not the fastest?

Because that is what you can expect on a normal try. Our fastest run took 2.4 seconds, the slowest 9.1.

Does it work in my language?

Yes. Speak in the language of your app. The invoice itself goes out in any of 100 languages.

Does Jiffy send without asking?

No. Jiffy shows the invoice and the recipient first. Nothing goes out until you tap.

Can I do it without speaking?

Yes. Type the same sentence, or make the invoice by hand in a few taps. Making invoices by hand works on every plan.
