Cortena is a Zenvoices alternative for teams that want an agent, not a denser rules engine.
Zenvoices is a capable Dutch scan and recognise platform with rich automation rules across Exact Online, Twinfield and other packages. Cortena.ai starts from a different premise. You brief an agent the way you would brief a bookkeeper, and it codes every field with a reason you can read. Here is a fair, factual comparison so you can decide which one fits.
Comparison written and reviewed October 2026. Where a Zenvoices detail is not publicly documented, we mark it "varies" rather than guess.
What Zenvoices does well.
We are not here to run Zenvoices down. It is a serious automation product for Dutch multi-administration teams. Credit where it is due.
Deep automation rules
Zenvoices invests in configurable conditions, authorisation schemes and self-learning recognition. Teams that want to encode process in rules find a lot of surface area.
Broad Dutch ERP coverage
Exact Online, Twinfield, AFAS and other packages are in scope. That multi-package reach helps accounting firms with mixed client stacks.
Matching on higher tiers
Purchase-to-pay matching, including 2- or 3-way match on selected plans and ERPs, is a real differentiator for stock and PO-heavy organisations.
If dense rules and PO matching are your main need, Zenvoices may be the right fit. The rest of this page is for teams who would rather brief an agent than maintain rule trees.
More rules still leave humans to finish the coding.
Zenvoices-class tools push hard on recognition and automation rules. Cortena.ai is agent-first. You instruct it once, in plain language, and it does the coding with a reason on every field.
Explainable AI on every field, not a black-box guess.
Cortena.ai codes the GL account, cost centre and VAT code, and shows why it chose each one: the precedent it followed, the rule it matched, the line it read. Your team reviews reasoning, not a bare suggestion.
- Account, cost centre and VAT code coded per line
- A plain-language reason attached to every field
- Precedent learning from your own corrections
Recurring office supplies from Staples Nederland B.V. Last 5 invoices booked to 4200 (office expenses), cost centre 100. Dutch VAT 21 %, reverse charge not applicable.
You brief it like a bookkeeper, not a rules engine.
Instead of expanding condition trees as edge cases appear, you write guidelines in plain language. Cortena.ai follows the briefing and asks when it is not sure.
- Guidelines in plain language, not rule trees
- Judgement on edge cases, questions when unsure
- One briefing that improves as your books do
The honest comparison.
Row by row, on the dimensions that actually change your week. Cortena facts are what we ship today. Zenvoices facts we keep to what is publicly documented, and mark the rest "varies".
Zenvoices is a capable product and its exact behaviour depends on plan, configuration and your accountant's setup. Where we could not verify a detail from public sources, we wrote "varies" instead of inventing one. If any fact here is out of date, tell us and we will correct it.
Who should pick which.
Zenvoices is the better fit when
- You need rich automation rules across mixed Dutch ERPs.
- PO and receipt matching on a higher tier is a hard requirement.
- Your firm already standardises on Zenvoices for many administraties.
Cortena is the better fit when
- You want coding done for you, with a reason on every field.
- You would rather brief an agent than grow a rules tree.
- You run several entities and want workflows to inherit.
- You want free white-glove setup and booking proposals into Exact or Twinfield.
Moving from Zenvoices takes about 15 days.
There is no ledger migration to dread. Your books stay where they are and your accountant keeps their tool. We connect your invoice inbox, learn your accounts and rules from your history, and run alongside you until the coding earns your trust.

Questions people ask before switching.
Yes, for teams that want an agent to do the coding rather than another rules-heavy scan platform to supervise. Both connect into Dutch accounting packages, but Cortena.ai codes every field with an explainable reason and is briefed in plain language.
Cortena focuses on agent-first coding, approvals and booking-ready export into Exact Online and Twinfield. Deep 3-way PO matching is not the centre of the product today. If PO matching is your primary need, Zenvoices on a matching-capable tier may fit better.
No. There is no ledger migration. Your books stay where they are, your accountant keeps their tool, and Cortena connects to your invoice inbox and learns from your history. Most teams are live in about 15 days with free white-glove setup.
Cortena is built for multi-entity work. Workflows and briefings inherit across administrations, and a root mailbox can route invoices to the right entity automatically.
We have tried hard to keep it fair. We credit what Zenvoices does well and, where a detail is not publicly documented, we mark it "varies" rather than invent a fact. If anything here is wrong or out of date, tell us and we will fix it.
