Accounts payable automation from received invoice to ready-to-pay payable
Sullivam automates the most time-consuming part of the AP cycle — receiving, reading, validating and recording invoices — and leaves payment decisions in your hands.
Which part of the AP cycle Sullivam covers
| Stage | With Sullivam today |
|---|---|
| Invoice intake | Automatic, from your Microsoft 365 inbox |
| Data capture | Automatic, with confidence and a quote per field |
| Validation (totals, duplicates, vendor, PO reference) | Automatic and deterministic |
| Exception handling | Review queue with the exact reason |
| Payable prepared | Automatic when everything checks out, or after approval |
| Payment approval and payment | Outside Sullivam — it does not execute payments |
| Posting to your ERP | Integrations on the roadmap |
Controls that protect the AP team
- Duplicates by file or by invoice number and vendor — including two copies arriving at the same moment.
- New vendors go to review by default; you can choose to reject or allow them.
- Automatic amount limit: above it, a person always signs off.
- Arithmetic: a total that does not add up cannot be approved, not even manually.
- Roles: owners and admins configure, reviewers approve or reject, members can only view. Every approval is signed with a name and time in the audit trail.
What the review queue looks like
Every invoice that needs a person arrives with the original document, the extracted values, the quote each value came from and the exact reason it stopped — “the total does not match subtotal plus tax”, not “validation failed”. The reviewer corrects a field, approves or rejects with a reason.
Approving is not a bypass. Every check runs again on the corrected values, with fresh duplicate and vendor lookups. A reviewer can vouch for a new vendor or an invoice without a PO; nobody can approve a duplicate or totals that do not add up. Once a new vendor's first invoice is approved, that vendor is known for the next one.
Getting started
- Pick the Microsoft 365 mailbox where supplier invoices arrive — ideally a dedicated one, not someone's personal inbox.
- An owner or admin connects it through Microsoft's own consent screen; Sullivam never sees the password.
- Set your limits: the highest amount that can be prepared without review, and what to do with a new vendor.
- Start strict, watch the review queue for a few weeks, and loosen the limits as the results earn it.
Choosing AP automation software: questions worth asking
- What does the tool do when it is not sure — reject, guess or ask?
- Can you see where every value came from, or only the result?
- Are business rules deterministic, or do they depend on a model's opinion?
- Does it catch duplicates that arrive at the same time, not just days apart?
- Is there an audit trail your auditor can follow?
- Which stages of the cycle does it really cover, and which stay with your team?
Sullivam's answers: it asks, it shows the quote, its rules are deterministic, it catches concurrent duplicates, it keeps a full audit trail, and it covers intake to prepared payable. See invoice automation for the full behaviour.

Frequently asked questions
Does Sullivam replace the AP team?
No. It takes the repetitive work and leaves exceptions, approvals and vendor relationships to your team.
Can Sullivam pay vendors?
No. It never executes payments or accesses bank accounts. It prepares the payable with its evidence.
