A receiving address for every department

Suppliers send invoices straight to the department's address, or your team forwards them. Each address stamps its entity and department on what it receives.

Use Cases

How finance teams use Acua day to day.

Stop downloading attachments by hand

AI reads each invoice and matches the vendor as it arrives. When AP opens the queue, the draft is waiting.

Replace the shared AP mailbox

One queue shows every package, its sender and what AI found. Nobody wonders whether a PDF was already entered.

AI routes invoices to the right entity

On a shared address, AI picks the entity from the vendor's default. Entity and department are set before anyone opens the bill.

Corrected invoices, no duplicates

AI recognizes a resent invoice as a new version of the existing bill. You replace or attach, and nothing is paid twice.

Frequently Asked Questions

How can suppliers send us invoices?
Four ways: by email to a department receiving address, through the no-login vendor upload link, through the Vendor Portal for connected suppliers, or by drag-and-drop upload inside Acua for one-off bills.
Does Acua create bills automatically from emails?
No. Every email becomes a package that waits for a reviewer. AI reads the invoice and proposes the primary file and supporting documents, but a draft bill is created only when someone accepts the package. This keeps forwarded threads from turning into duplicate bills.
What happens to attachments that are not invoices?
They stay in the package as supporting documents, credit notes, tax documents, or contracts, and are attached to the bill that is created. Files that cannot be processed, such as password-protected PDFs, remain visible with the reason they were excluded.
Which file types are supported?
PDF, PNG, JPG, JPEG, WebP, HEIC, and for the upload link also XLS and XLSX, up to 15 MB per file. Multi-page PDFs are read page by page.
We have several legal entities. Can each one receive separately?
Yes. A receiving address can be entity-specific, which stamps that entity on every bill it receives, or shared across the group, in which case the vendor's default entity applies. The vendor upload link asks the supplier to choose the buyer entity.
How does the inbox connect to the rest of accounts payable?
An accepted package becomes a draft bill with the vendor, line items, VAT, and withholding tax already filled in. From there it follows the normal path: PO linking and 3-way matching, approval routing, payment, and posting to your accounting software.
