Can I migrate from Google Document AI to Invofox?

Yes — most migrations take 1-2 days. Point your pipeline at Invofox's API and map the JSON output to your existing schema. There are no processors or GCP wiring to rebuild; our team can help with the schema mapping if your fields are non-standard.

Do I need a Google Cloud project to use Invofox?

No. Invofox is cloud-agnostic: one API key, runs anywhere, with no GCP project, IAM, billing or processor setup to manage. It drops straight into your stack regardless of where it runs.

Document AI makes me pick a processor per type — does Invofox?

No. One endpoint auto-classifies, splits and extracts any document type to your schema in a single call — no choosing a processor per document type, no chaining splitter/classifier/extractor processors yourself. For a deeper look at Document AI's production trade-offs, read the problems you'll run into using Google Document AI .

How does pay-per-correct-page compare to Document AI's per-page GCP pricing?

Document AI's bill depends on which processors you wire up — different per-page or per-document rates, volume tiers, and a separate per-version model-hosting fee — so the true cost is hard to predict (Google even illustrates it with worked examples). With Invofox you pay one predictable rate, only for the pages we extract correctly; report a mistake through our feedback endpoint and we credit that page back, and the model learns from the correction.

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. Document AI runs in Google Cloud only.

Google Document AI alternative: cloud-agnostic, no GCP lock-in.

Google Document AI is powerful if you're already all-in on Google Cloud and happy wiring up processors. Invofox gives engineers one cloud-agnostic API — validated, structured JSON from any document type, no GCP to manage, 99.2% accuracy, and you only pay for the pages we get right.

Invofox as a Google Document AI alternative

Google Cloud Document AI is a portfolio of building blocks — prebuilt processors, custom extractors, a splitter you wire up yourself — priced per piece and hosted per version. Teams look for a Google Document AI alternative when the surrounding pipeline turns out to be the actual project, or when running it means committing to GCP. Invofox is one API with that pipeline already assembled: ingestion, classification, splitting, extraction and validation behind a single call and a single bill. It runs wherever you need it, on-prem included.

When Invofox wins

No GCP commitment — the same API wherever your stack lives, including on-prem and inside your VPC.
The pipeline is included: classify, split, extract and validate in one call, with no per-version hosting to pay for.
Schemas stay editable and accuracy is contractual — renaming a field is a config change, not a re-labelling project.

// SIDE BY SIDE

Everything Document AI extracts — without the GCP setup or processor wiring.

Google Document AI is a strong choice if your stack already lives in Google Cloud and you want to assemble processors yourself. Invofox is the developer-first, cloud-agnostic API for teams that want validated, structured data from any document type through one endpoint — no GCP setup, no processor chaining, and accuracy written into the contract.

Capability	Invofox	Google Document AI
Built for	Developers — one API, structured JSON in, clean JSON out for any document type	Teams already on Google Cloud, wiring up processors in a GCP project
Cloud & lock-in	Cloud-agnostic — one endpoint, runs anywhere, no platform to adopt	Runs inside Google Cloud; needs a GCP project, IAM, billing and SDKs
Document coverage	Invoices, receipts, payslips, bank statements, contracts — any PDF or image, one endpoint	OCR plus specialized processors (invoice, receipt, ID…) selected per type
Setup model	No training, no templates — map your schema and go	Pick a processor, or a custom extractor — zero-shot generative or fine-tuned
Pricing	Pay only for the pages we extract correctly — one predictable rate, accuracy in the contract	Per-page or per-document depending on the processor, plus separate per-version model hosting — billed through GCP, complex enough that Google illustrates it with worked examples
Accuracy commitment	99.2% accuracy written into your SLA, validated against ground truth	No accuracy SLA or pay-for-accuracy guarantee
Built-in validation	Cross-field business rules (totals, tax, dates) before delivery	Confidence scores returned; business validation is yours to build
Classifier & splitter	Auto-detects document types and splits multi-doc files in one call	Splitter/classifier are separate processors you chain; split accuracy degrades on larger multi-document files
Zero-retention mode	Process, deliver, hard-delete — no copies, backups, or logs	Online requests aren't persisted to disk; batch deleted after processing
On-prem / private cloud	Same API, deployed inside your perimeter	Google Cloud only — no on-prem deployment
Compliance	SOC 2 Type II, ISO 27001, GDPR	SOC 2 Type II, ISO 27001, GDPR

Why teams switch to Invofox.

1 endpoint

One cloud-agnostic API.

No GCP project, IAM or billing to set up, no processors to chain — send a document to one endpoint and get clean, schema-mapped JSON, running anywhere.
+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.

Document AI bills through your GCP account whether the data's right or not. With Invofox, every page with a reported mistake is credited back.
