Email intake
Connect the inboxes vendors already use. APStack captures invoice documents, sender details, and thread context into one review queue.
Integrations
Every AP document gets one path to review.
Email, uploads, vendor submissions, portals, receipts, and payment platforms feed the same review queue, matching checks, vendor history, and approved QuickBooks posting path.

Approved posting only
APStack prepares the work, but QuickBooks receives the bill only after review and approval.

Built as the intake hub, not another tab to check.

File and document upload
Drop a vendor document directly into the same workflow. Uploads follow the same preparation, approval, and QuickBooks posting as email intake.
Live - proprietary
Vendor upload portal
Give suppliers a secure submission path. Their documents land beside the rest of the AP queue instead of becoming another inbox thread.

Vendor portal retrieval
APStack is being built to retrieve invoices from the supplier portals teams still check manually today.
In setup
Amazon Business retrieval
Amazon orders, paid invoices, receipts, credits, refunds, and PO references route into the same APStack review queue.
Coming soon
Payment platforms
Receipts, invoices, and payment records will feed the same AP queue instead of sitting in separate systems.
Live first
QuickBooks posting
Approved bill data posts to QuickBooks Online today. More accounting systems can follow the same review-before-posting pattern.
Document flow
Integrations should make AP documents easier to review, not harder to trace.
APStack treats every connector as part of the same review record: what arrived, where it came from, what it matches, and whether it is ready for QuickBooks.

Integration review
A solid connector foundation starts with clarity.
One review model
Every connector feeds the same AP record: original document, sender or connector context, extracted fields, review reason, approval state, and QuickBooks posting outcome.
Connector status is explicit
Live, planned, in-development, and setup states are separated so launch buyers understand what is available now and what is expanding next.
Review before accounting
Integrations are not treated as blind sync pipes. APStack uses them to prepare AP work for approval before the books are updated.
Proprietary edge
APStack is built for the places bills still hide.
Vendor upload portal
A private intake link gives vendors a clean way to submit documents directly into the same review queue.
Vendor portal retrieval
Supplier portals, utility portals, and vendor sites become invoice locations APStack can retrieve from directly.
