Sirena
Turns your inbox into part of your ERP's system of record
Every purchase, invoice, and sales email becomes a governed record, status and next action included.
Your ERP can't see what's happening in email
Purchase confirmations, payment reminders, remittance advice, and invoice attachments still move through inboxes, not integrations. Sirena exists to answer the questions that gap normally hides:
PROCUREMENT / BUYER
Which supplier has confirmed the PO?
Which purchase order has a price, quantity, or date variance?
ACCOUNTS PAYABLE
Which AP invoice is actually ready for payment?
Which invoice has quantity, tax, or freight variance?
Which mail is just a reminder, not a payable invoice?
SALES
Which quote is waiting on a customer reply?
Which sales order has a discount or quantity change pending approval?
ACCOUNTS RECEIVABLE
Which customer payment doesn't match an invoice, or covers several at once?
Which AR invoice is overdue or under dispute?
OPERATIONS / WAREHOUSE
Which supplier invoice is waiting on GRN?
Which PO has a partial receipt or quantity mismatch?
ADMIN
Which mailbox has processing errors right now?
Which AI classification needs a second look?
PO, AP, and Sales, on one shared record
Three different workflows, but one system underneath: the same tables, the same audit trail, the same rules, run by Genesis, Augusta Hitech's AI engine, applied here as Sirena's Overwatch layer. Every agent's output ships with a confidence score and a stated reason, and low-confidence results route to a human before they touch a financial workflow.
01PO / PROCURE-TO-PAY
THE NEED
Buyers lose hours confirming what a supplier actually agreed to, quantity, price, date, buried across reply threads.
WHAT SIRENA DOES
Sends PO mail, reads every supplier reply, and flags variance the moment it lands. GRN only syncs from ERP/WMS, never created from email.
AI AGENTS AT WORK
Mail Intake
Extracts confirmed quantity, price, and date from replies
Supplier Confirmation
Compares confirmation against the original PO
Exception Reasoning
Flags variances and recommends the next step
IMPACT
No PO counts as confirmed until the supplier's own words say so, and nothing pays against an order that was never confirmed.
02AP / ACCOUNTS PAYABLE
THE NEED
AP has to sort real invoices from statements, reminders, and duplicates across multiple mailboxes, then chase PO and GRN data just to know if it's safe to pay.
WHAT SIRENA DOES
Classifies every inbound mail before it can become a payable, bursts multi-invoice PDFs into separate records, and runs 3-way match automatically for PO invoices.
Non-PO invoices route to cost center and legal entity approval instead, never forced into PO matching.
AI AGENTS AT WORK
Mail Intake
Classifies mail, extracts invoice header and line items
AP Invoice
Prepares invoices for matching, flags missing fields
Document Bursting
Splits multi-invoice documents into separate records
Duplicate Detection
Checks supplier, invoice number, amount, and hash
Three-Way Match
Matches PO, GRN, and invoice, then recommends hold, correct, or release
IMPACT
Built to block 100% of exact-duplicate invoices before payment and keep non-invoice mail out of the payable pipeline entirely, both hard requirements, not tuning goals.
03SALES / QUOTE-TO-CASH
THE NEED
A quote reply with a discount ask or quantity change sits in an inbox until someone follows up, and one remittance covering three invoices means manual allocation.
WHAT SIRENA DOES
Reads customer replies the same way it reads supplier replies, extracting accepted terms, discount requests, and quantity changes, then matches remittance advice to invoices automatically.
AI AGENTS AT WORK
Mail Intake
Extracts accepted quantity, price, and terms from replies
Payment Advice
Allocates one remittance across multiple invoices
Exception Reasoning
Flags discount or quantity changes for approval
IMPACT
A Sales Order closes only once payment is fully matched, so revenue visibility reflects cash, not just an invoice sent.
Built for regulated finance operations
Role-based access
Restricted by legal entity, country, or business unit, so no one sees beyond their scope.
SSO-ready
Built for enterprise identity integration, one login, org-wide.
Encrypted by default
End-to-end encryption, with sensitive fields like bank details masked automatically.
Full audit trail
Every mail, decision, and override logged and immutable, down to who approved what.
Multi-entity data isolation
Each legal entity's data stays separate, even inside one shared platform.
ISO 27001 certified
Augusta Hitech holds ISO 27001 and ISO 9001:2015 certification.
