How to Connect Missive to Xero: The Complete Guide for Australian Businesses (2026)
The only way to connect Missive directly to Xero is through eggz. There's no native Missive-to-Xero integration, and no Zapier template covers the full financial document workflow. eggz sits between your Missive shared inbox and your Xero account, turning incoming emails into Xero transactions automatically — bills, quotes, and invoices, without manual data entry.
Why Missive users need a Xero integration
Missive is a collaborative inbox. Teams use it because it gives everyone visibility into customer conversations, lets you assign emails and add internal notes, and keeps client communication from disappearing into someone's personal Gmail.
The problem: Missive doesn't connect to your accounting system. Every time a supplier sends a bill, or a customer emails asking for a quote, someone still has to copy that information from Missive into Xero by hand.
That gap is where eggz fits.
What eggz does with your Missive inbox
When you connect Missive to eggz, three workflows become automatic:
Inbound bills. A supplier sends a PDF invoice to your Missive inbox. eggz reads the email, extracts the supplier name, amount, date, and line items, and creates a draft bill in Xero. You review and approve. No retyping.
Outbound quotes. A customer emails asking for pricing. You open eggz, create a quote, and send it. The quote syncs to Xero as a quote record. When the customer approves, eggz converts it to an invoice in Xero automatically.
Outbound invoices. If you skip the quoting step, you can also create invoices directly from Missive conversations. The invoice lands in Xero and goes to the customer from there.
The whole workflow — customer request to paid invoice — without opening Xero once.
Setting up Missive + eggz + Xero
The setup takes under 10 minutes and doesn't require developer access.
Step 1: Create your eggz account and connect Xero Go to app.eggz.ai and sign up. On first login, you'll be prompted to connect your Xero organisation. This is a standard OAuth connection — eggz gets permission to create invoices, bills, and contacts in Xero.
Step 2: Connect your Missive workspace In eggz settings, connect your Missive workspace via the Missive integration panel. eggz will ask for access to your team's shared mailboxes. You can choose which inboxes eggz monitors — typically you'd include your main accounts or billing inbox.
Step 3: Set your processing rules Decide which types of emails eggz should act on automatically. You can set it to:
- Auto-create draft bills from any email with a PDF attachment from known suppliers
- Flag potential bill emails from new senders for manual review
- Auto-process quote requests from specific customers
Step 4: Test with a real email Send a test invoice PDF to your Missive inbox and verify it shows up in Xero as a draft bill. This should take under 30 seconds from email receipt to Xero record.
Three statistics worth knowing
Missive is used by over 2,000 teams across 60 countries, with particular adoption among professional services firms and remote-first teams (Missive, 2025).
Australian businesses that automate invoice processing reduce their accounts payable processing time by 60–80%, according to a 2024 survey by Accounting Technology Solutions (ATS, 2024).
Manual data entry accounts for 37% of accounting errors in Australian small businesses, according to the Institute of Public Accountants (IPA, 2023). Automation removes the entry step entirely.
How this compares to Zapier
The first thing most people try when connecting Missive to Xero is Zapier. It's understandable — Zapier has Missive and Xero integrations, and it looks like it should work.
The problem: Zapier's Xero integration doesn't extract invoice data from email attachments. You can trigger a Zap when an email arrives in Missive, but you can't make Zapier read a PDF, pull out the invoice number, supplier ABN, and line items, and create a properly coded bill in Xero. Zapier moves data between fields — it doesn't do document extraction.
eggz does the document processing that Zapier can't. The OCR reads PDFs and images. The extraction logic pulls structured data from unstructured documents. The result is a properly coded Xero record, not just a logged email.
Who this works best for
The Missive + eggz + Xero stack works best for:
Professional services firms using Missive as a team inbox for client communication. Consultants, agencies, law firms, accountants who bill for time and expertise. The quote-to-invoice workflow is the main win.
Trades and construction businesses that run a shared Missive inbox for job requests and supplier ordering. When supplier bills arrive via email and client quotes go out regularly, eggz automates both sides.
Small teams with a dedicated admin person who currently spends a chunk of each week copying data from Missive into Xero. That person exists in most businesses of 3–10 people. eggz replaces most of that manual work.
What it won't do
Worth being clear about what eggz doesn't cover in the Missive context:
- It's not a full expense management system. Physical receipts and card transaction imports need a separate tool like Dext.
- It won't categorise transactions in Xero automatically — you still confirm the account and tax rate on each bill.
- It doesn't replace Missive's conversation management features. eggz reads financial emails; everything else in Missive works as normal.
Frequently asked questions
Does Missive have a native Xero integration? No. Missive doesn't have a direct integration with Xero. The only way to connect Missive to Xero for financial document processing is through eggz, which sits between the two systems and handles the data extraction and sync.
Can I use Zapier to connect Missive to Xero? You can build a basic Zapier workflow, but it won't extract invoice data from email attachments. Zapier can move email metadata between systems but doesn't do OCR or document extraction. eggz handles the document processing step that Zapier can't.
Does eggz work with all Missive inboxes? eggz connects to your Missive workspace and can monitor specific shared inboxes you choose. You control which inboxes eggz has access to during setup.
How long does setup take? Under 10 minutes for the basic configuration: connect Xero, connect Missive, set processing rules, test with a real email.
Does eggz work with Gmail as well as Missive? Yes. eggz integrates with both Gmail and Missive. If you use both (for example, personal Gmail for some client communication and Missive for team inboxes), you can connect both to eggz.
What happens if eggz can't read a PDF correctly? eggz flags the email for manual review rather than creating a partially filled record in Xero. You'll see it in the eggz review queue with a note on what it couldn't extract.
Can I use eggz for outbound invoicing through Missive? Yes. You create the invoice or quote in eggz, it syncs to Xero, and you can send it from there. eggz doesn't send emails on your behalf — it creates the Xero record, and Xero handles the outbound sending if you use that feature.
Is eggz the only Xero integration for Missive? Yes, as of June 2026. eggz is the only Xero add-on with a native Missive integration. Other Xero add-ons (Dext, Receiptor AI, DOKKA) support Gmail but not Missive.
