Overview

Nanonets Accounts Payable Automation is an AI-based system for managing invoice intake, validation, exception review, and ERP posting. It suits teams processing documents across multiple channels and applying formal purchasing and coding rules. Its broad workflow coverage is useful, but payment execution is outside its scope.

Key features

Invoice capture and validation

The system accepts vendor emails, PDFs, scans, EDI feeds, and supplier-portal documents without templates. Two- and three-way PO matching, rule-based GL coding, duplicate detection, and fraud checks extend it beyond basic invoice extraction. That range can help teams standardize varied incoming documents, though it does not remove the need for human review when a document or rule does not pass confidently.

Exception handling and ERP posting

Low-confidence matches and policy exceptions go to a reviewer alongside the document, failed rule, and context; processing pauses until the reviewer decides. This is a meaningful safeguard for teams that want control over edge cases, but it also means exceptions still require staff attention. 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 work. Security features 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, with SOC 2 Type I and Type II reports available upon request. These controls and deployment options make the product relevant to organizations with formal IT requirements; they do not change its lack of payment execution.

Pricing

Nanonets uses a freemium model, with paid usage starting at $100/mo. Every account starts with $50 in free credits and no card required; the credit offer is described as a free trial. 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 actual consumption depends on the workflow rather than a simple per-invoice rate.

Starter: Price not listed; up to 3 users. Its user cap makes it the natural starting point for a small team, but larger teams need another tier.
Starter paid usage: 100.00 USD per month, billed $100/month for 100 credits. This gives a defined monthly credit allotment, so teams should estimate workflow consumption against that allowance before relying on it at scale.
Growth: Custom pricing, with volume pricing by quote. It adds ERP and database integrations, custom integrations, AI reporting and analytics, and team-wide credit sharing, making it the fit for teams needing shared usage or broader integration and reporting.
Enterprise: Custom pricing. It adds private cloud or on-prem deployment, SAML SSO and SCIM, dedicated support and SLAs, and data residency. This is the tier for organizations with deployment, identity, residency, or support requirements beyond the lower plans.

Starter includes community support; Enterprise includes dedicated support and SLAs.

Platforms

Nanonets is available on web and through an API. That pairing supports browser-based operation and integration into other systems, but no mobile apps are offered among its listed platforms.

Who it's for

Nanonets is best suited to teams with document-heavy AP operations that need automated intake, purchasing-rule checks, controlled exception handling, and ERP posting. Its stated audience ranges from smaller companies to Fortune 500 enterprises, with tier features for both limited-seat use and more demanding deployment or governance needs. It is not the right standalone choice for a team that needs the same product to send supplier payments.

Pros and cons

Pro: Ingests several document types and channels without templates, reducing dependence on a single invoice format or delivery route.
Pro: Matching, coding, duplicate and fraud checks, plus reviewer-controlled exceptions, cover substantial AP validation work while keeping uncertain cases under human control.
Pro: ERP connectors, audit trails, enterprise security controls, and private deployment options accommodate a range of integration and governance needs.
Con: It does not execute payments, so organizations must use another service or process to pay suppliers.
Con: Usage-based credits and block-run pricing make spend depend on workflow complexity; the three-user Starter cap also limits its fit for larger teams.
Con: Growth and Enterprise require custom pricing, which makes their costs less predictable before obtaining a quote.

Alternatives

Ramp Bill Pay is worth considering if a free plan and Android or iOS access matter; its free plan has no monthly software fee, though payment fees vary by method and some ERP integrations require Ramp Plus. BILL Accounts Payable is a paid option with a free trial and Android, iOS, web, and API platforms for teams seeking a broader platform mix.

Rho may suit teams prioritizing a free service with no subscription, per-user, or platform fees; it charges a 1% foreign-currency transfer fee. Settle offers a free Launch plan with unlimited seats and transactions, while international wires cost $15.00.

Zahara is a paid alternative with a free trial and a Teams plan at 159.00 GBP per month, capped at 10 users, 120 purchase orders per month, and 250 AI-read invoices. Circulus is another paid option with a free trial; its Circulus AP Automation plan is 481.00 USD per month, with additional user and payment fees.

PairSoft AP Automation is an alternative with personalized quote pricing and unlimited users and storage. Zoho AP Automation has a free trial and a Premium plan with a three-license minimum, but its price is not visible.

Verdict

Choose Nanonets if your team needs rules-driven invoice intake, validation, exception review, and ERP posting across a document-heavy AP workflow. Its strongest case is the combination of broad capture, structured human review, and enterprise integration and control options. Look elsewhere if supplier payment execution is essential, or if you need predictable costs without estimating workflow-credit use.
