Dext vs Hubdoc vs Nanonets: Real Receipt and Invoice Processing Cost
Short answer
If you're already on Xero, Hubdoc comes bundled at no extra cost, and no published hard document cap was found on its own pricing page — there's rarely a reason to pay for anything else at low-to-moderate volume. Dext costs real money from document one ($25.21–31.50/month) but its price above the 250-document included allowance isn't a fixed overage rate — it's a continuous slider that adjusts by user count and document volume together, so there's no simple "$X per extra document" number to quote. Nanonets works completely differently: you buy a block of credits and burn through them per processing step, which means its effective cost per invoice depends on how many steps your workflow actually needs.
Pricing at a glance
| Dext | Hubdoc | Nanonets | |
|---|---|---|---|
| Entry price | Business: $31.50/mo (monthly), $25.21/mo (annual, $302.50/year) | $12/month standalone, flat | $200 in free credits to start, no platform fee |
| Included volume | 250 documents/month, up to 5 users | No published hard cap | N/A — consumption model |
| Free-with-Xero | No | Yes — bundled free with Xero's Early, Growing, and Established (US) plans | No |
| Above the included allowance | Continuous on-page slider (scales with both users and documents); not a fixed per-document overage rate | Published pricing does not expose a volume overage — no hard cap was found, but this is not confirmed as unlimited | Additional credits purchased as needed; ~$0.10–0.30 per processing block |
| Add-ons | AI Assist, line-item extraction, bank statement extraction — all separate paid add-ons | None published | N/A |
Dext restructured its plan names during 2026 — if you see references to a "Business Plus," "Premium," or "Enterprise" Dext tier at different prices than shown above, that's the pre-restructure lineup.
What the headline price excludes
Dext's core AI capabilities are add-ons, not included in the base price. AI Assist, line-item extraction, and bank statement extraction all cost extra on top of the $25.21–31.50/month Business price — the number most people quote as "what Dext costs" doesn't include what most buyers would consider the actual AI part of the product. Exact add-on pricing isn't publicly confirmed at this time.
Nanonets bills per processing step, not per document. A single invoice that needs data extraction plus classification plus signature detection burns three separate credit charges, not one. Nanonets' own example puts a typical invoice at 4–6 blocks, coming in under $2 end-to-end — but that's a workflow-dependent number, not a fixed per-document rate.
Worked scenarios
Freelancer or small business already on Xero, under 250 documents/month
Hubdoc, bundled free with an Early, Growing, or Established Xero plan, is very likely sufficient on its own — $0 in additional software cost. Dext's Business tier at $25.21/month (annual) comfortably covers this volume if you need it for a non-Xero reason. Nanonets' $200 in starting credit, at roughly $0.10–0.30 per block and 4–6 blocks per invoice, covers somewhere in the range of 65–500 invoices before you'd need to buy more credit — plenty of runway for very low volume, but it's a one-time grant, not a recurring monthly allowance.
500 documents/month
This exceeds Dext Business's 250-document included allowance, which means the price moves onto Dext's slider. The two confirmed reference points on that slider are the $25.21/month floor and a roughly $911.75/month point at 500 users and 50,000 documents — 500 documents/month alone will land somewhere above the floor, but there is no published formula to calculate an exact figure without checking Dext's own live pricing calculator. Hubdoc, notably, has no published hard document cap and its pricing doesn't expose a volume overage, so this scenario is modeled at its published flat $12/month (or $0, bundled with Xero) — subject to whatever practical product or workflow limits may exist that simply aren't published anywhere. Nanonets, at roughly 4–6 blocks per invoice and $0.10–0.30 per block, works out to an illustrative $200–900/month at 500 invoices (using the published rate ranges, not a quoted total) — a rough estimate rather than an exact figure.
5,000 documents/month
Dext's slider has no published reference point at exactly this volume; the nearest known data point (500 users/50,000 documents ≈ $911.75/month) is for 10 times this volume, so an exact 5,000-document figure genuinely isn't calculable from public information. Hubdoc, again, has no published cap and its pricing doesn't expose a volume overage, so this scenario is modeled at its published flat $12/month — though a workflow generating 5,000 documents/month may run into practical product or workflow limits that simply aren't documented publicly, regardless of what the price implies. Nanonets, using the same illustrative math as above, would run roughly $2,000–9,000/month at this volume (again, an estimate from the published per-block rate range, not a vendor-quoted figure).
Break-even and crossover
The real crossover here isn't a dollar figure — it's a feature ceiling. Hubdoc has no published hard document cap and its pricing page doesn't expose a volume overage, which makes it the default choice at any scale where its simpler capture-and-store functionality is enough — though "no published cap" isn't the same as a confirmed unlimited allowance, and very high-volume workflows should verify this directly with Hubdoc rather than assume it holds indefinitely. The point at which a business needs Dext's paid automation or Nanonets' workflow flexibility instead is tied to needing capabilities Hubdoc doesn't have — deeper accounting-platform integrations beyond Xero, more sophisticated line-item extraction, or custom multi-step workflows — not to hitting a specific document count. One widely cited rule of thumb pegs Hubdoc as sufficient for businesses under roughly $3 million in revenue or 200 bills a month, though this is a guideline rather than a hard technical limit.
Who pays more, and when
- Already on Xero, moderate volume, simple needs: Hubdoc, effectively free, is the default and hardest to beat on price.
- Not on Xero, or need AI Assist/line-item extraction specifically: Dext's $25.21–31.50/month base price is the entry cost, with add-ons on top for the AI-specific features.
- High volume with custom multi-step workflows (classification, signature detection, and extraction all on the same document): Nanonets' consumption model can work out cheaper or more expensive than Dext's slider depending entirely on how many processing steps each document actually needs — there's no universal answer here, only a workflow-specific one.
Limitations and uncertainty
Dext's exact overage behavior above 250 documents/month is not a fixed rate that can be quoted — it is priced dynamically through an interactive calculator on Dext's own site, and any number given for volumes between the two known reference points (the $25.21 floor and the ~$911.75 point at 500 users/50,000 documents) is an approximation, not a quote. Nanonets' per-invoice figures at volume in this article are illustrative calculations using the published per-block rate range and Nanonets' own stated 4–6-block typical invoice — they are not figures Nanonets itself publishes as a flat monthly cost, and actual cost will vary by workflow complexity.
