Invoicing that lives in Slack and Discord

Invoices in, invoices out. All from your workspace.

Send invoices to clients and collect them from contractors, then hear about it in Slack or Discord the moment anything changes.

Add Du3 to your workspaceSee how it works

Works with Slack and Discord. More apps soon.

No workspace yet? Use Du3 on the web and in the app. Connect one any time.

How it works

Three steps. Then it runs itself.

Set it up once. Then your team does it all from one channel.

  1. Connect your workspace

    Add Du3y to Slack or Discord and pick the channel where money news goes.

  2. Send or collect invoices

    Make an invoice for a client, or share a link so contractors can bill you.

  3. Get paid and stay in the loop

    Du3y posts when invoices are viewed, paid, late, or waiting for someone.

Both directions

Money going out. Money coming in.

Send invoices to clients

Outbound
  • Make an invoice on the web or in your workspace with /du3 new.
  • Your client gets an email with a clean invoice page and a PDF. No account needed.
  • Du3y reminds you when it is late, so nothing slips.
How sending invoices works

Collect invoices from contractors

Inbound
  • Share one link. Contractors fill it in and send.
  • Every invoice lands in one list, next to the ones you sent.
  • Required fields must be filled before anyone can send, so nothing is missing.

Your fields, your look

Ask for exactly what you need.

Add your own questions to any invoice link — text, numbers, dates, dropdowns, files or bank details — and mark each one Required or Optional. No more chasing PO numbers.

  • Your own web address: yourcompany.usedu3.com
  • Your name and logo on every invoice and link.
  • Different links for different people, like one just for Amara.
For contractors

Questions

Good questions.

Do my clients need an account?

No. They get an email with a link to your invoice and a PDF. Nothing to sign up for.

Is my data kept separate per workspace?

Yes. Each workspace you connect belongs to one Du3 organization, and every request is checked against it. Du3y can only see and change your own company's invoices.

Can I add my own fields?

Yes, on the Team and Business plans. Add fields like PO number or bank details to a link and mark each one Required or Optional.

What currencies can I use?

You choose the currency on each invoice, and set a default for your company. Today you can use Nigerian naira (NGN), US dollar (USD), British pound (GBP), Euro (EUR), Ghanaian cedi (GHS), Kenyan shilling (KES), South African rand (ZAR), Canadian dollar (CAD).

What if my team doesn't use Slack or Discord?

Use Du3 on the web and in the app. You can connect a workspace any time. More apps soon.

Can contractors see other people's invoices?

No. A contractor only ever sees the invoices they sent.

Is there a free trial?

There is no free tier. Teams in our private beta get 14 days with every feature, free, and then pick a plan.

What happens if my plan ends?

Nothing is deleted. Your account becomes read-only: you can still view and export your invoices, and you can pick a plan at any time to carry on.
