Overview

The product coordinates AP work around supplier terms, tolerance tables, coding rules, and approval matrices. It goes beyond invoice-field extraction: it validates documents, pauses for human decisions when confidence is low or policy rules fail, then posts data after checks pass. That makes it a stronger fit for organizations seeking controlled invoice processing than for buyers looking for an end-to-end payment platform.

Key features

Invoice intake and validation

Nanonets accepts vendor emails, PDFs, scanned paper, EDI feeds, and supplier portal documents without templates. It supports two-way and three-way PO matching, business-rule-based GL coding, duplicate detection, and fraud checks. This range can accommodate mixed supplier channels, while the review process still leaves people responsible for uncertain cases.

Human review and ERP posting

Low-confidence matches and policy exceptions go to a reviewer with the document, the failed rule, and context; processing waits for a decision. That pause is a useful safeguard where exceptions should not be silently passed through, though it means the workflow still depends on timely human review. Once checks pass, validated data is posted to the ERP with an audit trail.

Integrations and controls

Pre-built connectors cover SAP S/4HANA, Oracle, NetSuite, Dynamics 365, QuickBooks, Xero, and Sage, with webhooks and REST support for other integration routes. Security controls include SAML, OIDC, SCIM provisioning, role-based access, audit logs, private deployment options, data residency, AES-256 encryption at rest, and TLS 1.3 in transit. Nanonets states that it is SOC 2 compliant and ISO/IEC 27001 certified; SOC 2 Type I and Type II reports are available upon request.

Pricing

Nanonets uses freemium pricing, with paid usage from $100/mo. Every account starts with $50 in free credits and no card is required; Nanonets describes this as a free trial. The Starter plan supports up to 3 users and includes community support. Starter paid usage is 100.00 USD per month, billed $100/month for 100 credits.

Charges are based on workflow block runs: $0.02 per simple operation run, $0.10 per standard AI run, and $0.30 per complex AI run. Typical invoice processing uses 4–6 blocks per document, so the credit allowance and workflow mix matter when estimating volume. The entry usage tier gives a defined 100-credit allotment, but teams processing many documents should check expected run consumption before committing.

Growth has custom pricing based on volume and adds ERP and database integrations, custom integrations, AI reporting and analytics, and team-wide credit sharing. It is the more appropriate tier for teams needing shared usage and broader integration or reporting capabilities. Enterprise also has custom pricing, with private cloud or on-prem deployment, SAML SSO and SCIM, dedicated support and SLAs, and data residency; those controls and service commitments make it the tier for organizations with stronger deployment or support requirements.

Platforms

Nanonets is available on the web and through an API. It is not a payment-execution product, so teams need a separate way to send supplier payments.

Who it's for

Nanonets is aimed at teams of different sizes, from smaller companies to Fortune 500 enterprises, that handle document-heavy AP. It is most compelling where invoices arrive through varied channels and matching, coding, exception review, and ERP posting are the central needs. Buyers whose main requirement is payment execution should look elsewhere or pair it with another service.

Pros and cons

Pros

Broad invoice intake: Email, PDFs, scans, EDI, and supplier portals are supported without templates, helping teams consolidate varied document sources.
Controlled exceptions: Reviewers receive the document and reason for an exception, and the agent waits for a decision instead of continuing automatically.
ERP coverage and audit trail: Named connectors span major accounting and ERP systems, and validated postings retain an audit trail.
Enterprise controls: Identity provisioning, encryption, deployment choices, and stated compliance credentials support organizations with security and governance needs.

Cons

No payment execution: The workflow can reach posting and payment-run preparation, but does not send payments.
Usage-based budgeting: Per-run charges and the typical 4–6 blocks per invoice make actual document volume and workflow complexity important to the bill.
Several tiers require a quote: Growth and Enterprise use custom pricing, so buyers seeking a fixed quote for broader capabilities must contact Nanonets.

Verdict

Choose Nanonets when invoice intake, matching, policy checks, human exception review, and ERP posting are the AP work you want to automate across varied document sources. Its strongest case is the combination of flexible intake and controlled handoffs into established systems. Look elsewhere if sending payments is central, or assess the credit economics carefully if invoice volumes and workflow complexity are high.
