What if I rely on Nanonets's no-code workflow builder?

Most teams find they don't need it once everything ships as validated, structured JSON to the tools they already use. Invofox is API-first: classification, splitting and cross-field validation run inside one call. If you need a UI for low-confidence pages, we provide an opt-in review queue — but it's not the default workflow.

Do I need to train models or label samples?

No. Send a document and get schema-mapped JSON out of the box across invoices, receipts, payslips, bank statements, IDs, contracts and more. You can customize the schemas or define entirely new document types — there's no per-document-type model training to set up and maintain.

How does pay-per-correct-page compare to Nanonets's per-block credits?

Nanonets bills per block, so you pay for every step of every workflow — and because each document runs a different number of blocks, the true cost per document is hard to forecast before you're live. Invofox is flat and predictable: you pay only for the pages we extract correctly, with no charge to retry a page we got wrong. Report a mistake through our feedback endpoint and we credit that page back, and Invofox learns from the correction so it doesn't repeat.

Do you support on-prem deployment?

Yes — with the same API surface, inside your VPC or on-prem when data residency or compliance requires it. With Nanonets, on-prem / private-cloud deployment is gated to the Enterprise plan.

Invofox vs Nanonets: one API, accuracy in the contract.

Nanonets is a no-code workflow platform priced per block, with no accuracy guarantee. Invofox gives engineers one API — validated, structured JSON at 99%+ accuracy written into your SLA, and you only pay for the pages we get right.

Everything Nanonets does — without the workflow builder or the per-block bill.

Nanonets is a capable platform if you want a no-code studio to build document workflows. Invofox is the developer-first API for teams that want validated, structured data from one endpoint — no blocks to wire up, no per-block math, and accuracy in the contract.

Capability	Invofox	Nanonets
Built for	Developers — one API, structured JSON in, clean JSON out	Builders who want a no-code workflow studio plus an API
Setup	No training, no workflow to build — send a document, get schema-mapped JSON	Configure a block-based workflow; pre-trained or custom-trained models
Pricing	Pay only for the pages we extract correctly — flat and predictable, accuracy in the contract	Per-block credits — every step bills separately and each document runs a different number of blocks, so the real cost per document is hard to estimate; volume pricing is quote-based
Accuracy commitment	99%+ accuracy written into your SLA, validated against ground truth	Strong benchmark accuracy, but no pay-for-accuracy guarantee
Built-in validation	Cross-field business rules (totals, tax, dates) before delivery	Validation built as blocks in the workflow you configure
Classifier & splitter	Auto-detects document types and splits multi-doc files in one call	Classification and splitting as separate workflow blocks
Async webhooks	Cloud-agnostic async API with standard HTTP webhooks	REST API with webhook support for async jobs
Zero-retention mode	Process, deliver, hard-delete — no copies, backups, or logs	Documents retained for review and workflow processing
On-prem / private cloud	Same API, deployed inside your perimeter	Docker / VPC / on-prem on the Enterprise plan
Compliance	SOC 2 Type II, ISO 27001, GDPR	SOC 2 Type II, ISO 27001, GDPR

Why teams switch to Invofox.

1 endpoint

One API, no workflow to build.

Send a document, get clean, schema-mapped JSON. No no-code studio to configure, no blocks to wire up — Invofox drops straight into your codebase.
+99% accuracy guaranteed

Accuracy in the contract.

Per-field accuracy targets are part of your SLA, validated against ground truth. If a page isn't extracted perfectly, you don't pay for it.
$0 if we make a mistake

Pay only for correct data.

Every page where a mistake is reported through our API is credited back — no per-block math to forecast, no paying again to retry.
