EMAIL INTEGRATION · OUTLOOK

The invoice is buried in a thread.Not anymore.

In a Microsoft 365 shop, vendor invoices arrive as attachments on message twelve of a nineteen-message thread. CashFish lifts each one out, reads it, and queues it for review — while the thread carries on without you.

Everyone read the thread.
Nobody recorded the invoice.

A thread is a conversation with an attachment stuck to it. The conversation gets all the attention, and the attachment is the part with the due date.

RE:RE:
Message twelve of nineteen
The invoice sits three replies above the delivery argument, beneath a signature block and a scanned PO. Four people have read the thread this week. The invoice is still not in the books.

The shared mailbox nobody owns
Three people can open it, so two of them assume the third is handling it. The cleaning invoice sits unopened for eleven days and then it is simply late.

Terms that live inside a PDF
Due dates exist, but only in attachments. The payment schedule is whatever somebody remembers on the morning they open the folder.

The same invoice, three copies
The vendor sends it, whoever ordered forwards it, and finance re-sends it just in case. Two of the three get entered, and the ledger says you owe twice.

Outlook is doing exactly what mail does. It is keeping the conversation, not the accounting.

02What comes in

Attachments, message bodies,
and whole shared mailboxes.

CashFish reads the mailbox the paperwork already arrives in — personal or departmental — and lifts each financial document out of it, thread depth irrelevant.

PDF invoices, PNG and JPEG receipt images, and billing details embedded straight in the message body, including the HTML invoice tables from vendors that never attach a file. Every record keeps the source mailbox it came from.

What the inbox
was already holding.

A week of the AP mailbox, exactly as it arrived: the subject line, the fields CashFish pulled off the document, and where the record went. One is held for a person to look at.

Read-only throughout. No reply was sent, no message was moved to a folder, nothing was marked read or deleted — the threads look untouched because they are.

04What changes

Payables that
line themselves up.

Once documents leave the thread, three things follow: the record exists, the due dates form a schedule, and a person still signs off before anything counts.

Every extraction waits in a review queue. Approve it, recategorize it or dismiss it — nothing counts because a machine said so.

01
The attachment leaves the thread
An invoice on message twelve is still an invoice. CashFish lifts the PDF, reads vendor, amount and due date, and creates the record — the thread itself stays exactly as it was.
02
Payables line up by due date
Extracted due dates turn a pile of emails into a schedule. You see what's owed and when — before anything is late, not after.

Nothing posts without a person
Every extraction waits in a review queue. Duplicates from CC'd copies and re-sent threads are filtered out before you ever look at the list.

05How to begin

Three steps,
one of them your IT policy.

Microsoft runs the sign-in. Some tenants add an admin-consent screen before an app can read mail — that step belongs to your organisation, not to us.

01
Sign in with Microsoft
Works with Outlook.com, Hotmail and Microsoft 365 accounts. On some work tenants Microsoft shows an admin-consent step first — that's your IT policy, not ours.
02
Grant read-only mail access
CashFish requests reading permissions only. Disconnecting — from your Microsoft account or from CashFish's Connection Health panel — cuts access immediately.
03
Review the backfill
The first pass imports 150 days of mail; after that, CashFish checks every 5 minutes. Extracted invoices and receipts hold in the review queue until someone approves them.

06Connections that pair with it

What sits well beside Outlook.

Any IMAP mailbox connects the same way. Bank sync across 12,000+ institutions is read-only and opens on Growth, along with store and payment connections like Stripe and WooCommerce; QuickBooks and Xero import one way into CashFish and are never written back to.

07The plan for this

Point CashFish at your Outlook mailbox.
Every extraction still waits for you.

Microsoft OAuth, nothing written back, every extraction held for approval. The trial runs 4 days, fully refundable.

Outlook connects on the Starter plan. Bank sync and store, CRM and payment connections are where Growth comes in; approval routing across a team needs Teams.
