Invoice OCR API Pricing: What Vendors Charge Per Invoice

Invoice OCR API pricing runs from about a penny an invoice on the hyperscalers' prebuilt models to over a dollar an invoice on full-workflow platforms. Here is every published rate, per invoice, verified from each vendor's own pricing page, and what each price does and does not include.

Last updated July 2026.

Invoice OCR API pricing ranges from about one cent per invoice on the hyperscalers' prebuilt models to more than a dollar per invoice on full-workflow platforms. The spread is not about accuracy. It is about how much of the job each price buys: a raw field extraction call, or the whole pipeline of classify, extract, validate, review, and post. Compare the numbers without knowing which you are getting and you will pick the wrong tool.

Invoice OCR API pricing, per invoice

The table below is the cost to extract structured fields from one single-page invoice, using each vendor's most relevant published rate as of July 2026. Rates were read from each vendor's own pricing page.

Vendor	Cost per single-page invoice	Billing unit	What the price buys
Mistral Document AI	About $0.005	Per page ($5 per 1,000)	Structured document extraction call
Azure prebuilt invoice	About $0.01	Per page ($10 per 1,000)	Invoice fields from one model call
AWS Textract Analyze Expense	About $0.01	Per page ($10 per 1,000)	Invoice and receipt fields from one call
Google Document AI invoice parser	About $0.10	Per page, billed in 10-page blocks	Invoice fields, but a short invoice bills as a 10-page block
Docparser	About $0.13 to $0.39	Per credit (1 document up to 5 pages)	Fields from a parsing rule you build per layout
Veryfi	$0.16	Per document (up to 15 pages)	Invoice fields via API or capture SDK
Nanonets	About $1.20 to $1.80	Per block run	Classify, extract, validate, and post the whole workflow
DocuOCR	About $0.014 to $0.02	Per page	Template-free extraction with validation, review, and export

How much does invoice OCR cost?

For a single-page invoice, roughly one cent on a hyperscaler's prebuilt model, about sixteen cents on Veryfi, and over a dollar on a full-workflow platform like Nanonets. The wide range is real and it is not a quality signal. The cheap end buys one model call that returns fields and nothing else. The expensive end buys the surrounding pipeline: sorting a mixed batch, validating the numbers, routing low-confidence reads to a human, and posting the result into your accounting system.

The number you should actually budget is your per-invoice API cost plus the engineering time to build and maintain everything the API does not do. On a penny-a-page model that surrounding work is entirely yours. That is why a one-cent rate and a one-dollar rate can end up costing the same company the same money.

What is the cheapest invoice OCR API?

On headline rate, Mistral Document AI at about $0.005 a page and the Azure and AWS prebuilt invoice models at about $0.01 a page are the cheapest published options. They return invoice fields from a single call. What they do not do is classify a stack of mixed documents, validate the extracted totals against your rules, give a reviewer a screen to fix low-confidence fields, or move the data into your ERP. If your invoices all arrive in one clean format and you have engineers to build the rest, the cheapest API is genuinely cheapest. If not, the sticker price is only the first line of the bill.

Why is Google's invoice parser more expensive per invoice than Azure's?

Because Google bills its prebuilt invoice parser in 10-page blocks. The rate is $0.10 per 10 pages, which looks identical to Azure's $10 per 1,000 pages until you send a one-page invoice. On Azure a one-page invoice is one billable page, about a cent. On Google the same one-page invoice consumes a 10-page block, so it costs about ten cents, ten times more. For short invoices at volume that block-rounding is the single biggest hidden cost in Google Document AI's prebuilt processors, and it does not appear on the headline rate.

Is a per-page or a per-invoice model cheaper?

It depends on invoice length. Per-page vendors like Azure and AWS win on single-page invoices, where a cent a page beats Veryfi's sixteen cents a document. Per-document vendors like Veryfi win as invoices get longer, because a 10-page invoice is still one $0.16 document on Veryfi but ten billable pages elsewhere. Docparser's credit sits in between at one document up to five pages, but it needs a parsing rule built for each layout. The rule of thumb: short invoices favor per-page pricing, long invoices favor per-document pricing, and variable layouts favor a template-free tool that needs no per-layout setup at all.

What does invoice OCR API pricing not include?

Almost everything around the extraction call. None of the per-page rates include document classification for a mixed inbox, business-rule validation such as checking that line items sum to the total, a human review screen for low-confidence fields, or the integration that posts approved data into your accounting or AP system. Those are the parts of an accounts payable workflow that actually take time, and a raw API leaves all of them to you. If you want the extracted data to flow straight into approvals and payment, an accounts payable automation layer handles that downstream step that a bare OCR API does not touch.

The short version

Invoice OCR API pricing spans two orders of magnitude, from half a cent to nearly two dollars an invoice, and the spread reflects scope, not accuracy. Price the whole job, not the API call: cheap per-page extraction plus the pipeline you build, against a per-document or workflow price that includes more of it. Watch Google's 10-page block minimum on short invoices, weigh per-page against per-document on your real invoice length, and test on your own documents before you commit.
