Nanonets vs Rossum vs Veryfi: Real Invoice OCR Cost per Document
Short answer
These three vendors don't just charge different prices — they charge in completely different units, which is the actual story here. Nanonets meters every individual processing step as a credit. Veryfi charges a flat monthly platform fee plus a small per-document rate. Rossum charges one flat annual fee for effectively unlimited seats, with no published document ceiling — meaning at high enough volume, Rossum's flat fee can end up dramatically cheaper than either consumption-based competitor, or it can force you into a custom Business quote if you exceed a limit nobody outside Rossum can see.
Pricing at a glance
| Nanonets | Rossum | Veryfi | |
|---|---|---|---|
| Model | Consumption — credits billed per processing "block" | Flat annual platform fee | Base subscription + per-document usage |
| Free tier | $200 in starting credit, no platform fee | 14-day free trial | Free trial available |
| Entry price | Pay-as-you-go from the $200 starting credit | $18,000/year (Starter), unlimited seats | $500/month (Starter) |
| Usage rate | ~$0.10–0.30 per processing block; a typical invoice runs 4–6 blocks (under $2 end-to-end) | Included allowance not published — treat Starter as a flat fee of unknown volume ceiling | $0.16/invoice, $0.08/receipt, on top of the $500/month base |
| Above entry tier | Buy more credit as needed | Business, Enterprise, and Ultimate tiers — genuinely custom-quoted | Scales with usage automatically; no separate published tier |
| Contract terms | None — pay as you go | 1-year minimum commitment | Not specified beyond monthly billing |
What the headline price excludes
Rossum's $18,000/year buys an unknown amount of actual processing volume. The Starter tier includes document ingestion, Rossum's AI extraction engine, a 12-month document archive, and API access — but nowhere in Rossum's public materials is there a stated cap on how many documents that $18,000 actually covers before you're pushed to a custom quote. Budget it as a flat platform cost and confirm the real ceiling directly with Rossum before committing.
Nanonets' per-invoice cost depends entirely on your workflow. A simple extraction-only workflow might cost under $1 per invoice; add classification, signature detection, or checkbox recognition to the same document and you're paying for each of those as a separate block. There's no single "Nanonets price per invoice" — only a price per step.
Worked scenarios
The figures below are monthly volumes. Nanonets' range reflects its published $0.10–0.30 per-block rate across a 4–6 block typical invoice (roughly $0.40–$1.80 per invoice); actual cost depends on your specific workflow.
1,000 documents/month
| Estimated monthly cost | |
|---|---|
| Nanonets | $400–1,800 |
| Rossum | $1,500 (flat Starter fee, if volume fits under the unpublished ceiling) |
| Veryfi | $500 + (1,000 × $0.16) = $660 |
At this volume, exact ordering depends on how many processing blocks your specific workflow needs: Nanonets can be the cheapest of the three at the low end of its range (simple, few-block workflows), but its high end ($1,800) exceeds Rossum's flat fee, and even its low end doesn't clearly beat Veryfi's $660 unless your workflow runs closer to 2–3 blocks per invoice than the stated 4–6. Veryfi's $660 is cheaper than most of the Nanonets range at this volume. Rossum's flat $1,500 fee is the most expensive of the three unless its enterprise-grade extraction accuracy or workflow features justify the premium on their own merits — there's no single "cheapest" answer here without knowing your own block count.
10,000 documents/month
| Estimated monthly cost | |
|---|---|
| Nanonets | $4,000–18,000 |
| Rossum | $1,500 (flat, if this volume still fits under the unpublished ceiling) |
| Veryfi | $500 + (10,000 × $0.16) = $2,100 |
This is where Rossum's flat-fee model starts to look genuinely attractive — if its unpublished Starter allowance actually stretches this far. If it doesn't, this volume forces a custom Business quote, and the comparison changes entirely. Confirm directly with Rossum before assuming the $1,500/month figure holds at this scale.
50,000 documents/month
| Estimated monthly cost | |
|---|---|
| Nanonets | $20,000–90,000 |
| Rossum | $1,500 only if Starter covers this volume; public information does not establish that it does |
| Veryfi | $500 + (50,000 × $0.16) = $8,500 |
At high volume, the gap between a flat annual platform fee and two consumption-metered competitors becomes enormous — this is exactly where Rossum's pricing philosophy either pays off spectacularly or forces an expensive custom conversation, and there's no way to know which from public information alone.
Break-even and crossover
Because Rossum's Starter tier is a flat fee with an unknown ceiling, there's a genuine, calculable question buried in these numbers: at what volume does Rossum's $1,500/month flat cost undercut Veryfi's usage-based bill? Setting Veryfi's cost equal to Rossum's flat fee: $500 + (0.16 × n) = $1,500, solving for n gives roughly 6,250 documents/month. Below that volume, Veryfi is cheaper; above it, Rossum's flat fee wins — provided your volume stays under whatever cap actually applies to Rossum's Starter tier, which is the one number in this entire article that only Rossum itself can confirm.
Who pays more, and when
- Low, unpredictable volume, or workflows needing multiple processing steps per document: Nanonets' pay-as-you-go credit model is the most flexible, and can be the cheapest option at low volume depending on how few processing blocks your workflow needs — but its own published range overlaps with and can exceed Veryfi's cost at the same volume, so this depends on your specific workflow rather than being a fixed ranking.
- Steady, moderate volume with straightforward invoice/receipt extraction: Veryfi's predictable base-plus-usage structure is easy to forecast and reasonably priced through the low tens of thousands of documents per month.
- High, consistent volume, and willing to commit to a year: Rossum's flat annual fee could be dramatically cheaper than either alternative — but only if your volume actually fits under its unpublished ceiling, which makes this the one scenario where a direct sales conversation is not optional before committing.
Limitations and uncertainty
Rossum's Starter tier document allowance is not published anywhere in Rossum's own materials and could not be confirmed independently — every Rossum figure above assumes the flat $18,000/year fee applies at the stated volume, which may not hold in practice. A competitor's marketing material cites Rossum's effective enterprise-scale cost at "roughly $10+ per document," which would suggest the Starter tier's real ceiling is much lower than 50,000/month — but that figure comes from a rival vendor, not from Rossum, and should be read with appropriate skepticism rather than treated as fact. Nanonets' per-invoice figures at volume are illustrative calculations from published rate ranges, not quoted totals.
