Cortena is a GetMyInvoices alternative for teams that want coding done, not only invoices collected.
GetMyInvoices is strong at pulling invoices from thousands of supplier portals and handing them into DATEV and other tools. Cortena.ai starts further down the process. 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 GetMyInvoices detail is not publicly documented, we mark it "varies" rather than guess.
What GetMyInvoices does well.
We are not here to run GetMyInvoices down. Portal collection is a real problem, and they solve a large part of it. Credit where it is due.
Portal fetch at serious scale
Automatic download from a very large catalogue of supplier portals is the core job. For teams drowning in logins, that alone is valuable.
DATEV handoff including Rechnungsdatenservice
GetMyInvoices can push documents and structured data toward DATEV Unternehmen online, including Rechnungsdatenservice 1.0 paths that tax advisors recognise.
Extra capture channels
Email import, mobile scan and bank or card connections help gather stray documents that never arrive as clean PDFs.
If collecting documents is your main bottleneck and coding still happens in DATEV, GetMyInvoices may be enough. The rest of this page is for teams who want the coding itself done with readable reasons.
Collecting invoices is not the same as coding them.
GetMyInvoices-class tools centre on fetching, OCR and forwarding. Coding, cost centres and VAT keys still land on your team or your Steuerberater. Cortena 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 codes the GL account, cost centre and BU key, 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 BU code coded per line
- A plain-language reason attached to every field
- Precedent learning from your own corrections
Recurring server hosting from Hetzner Online GmbH. Last 6 invoices booked to 6837 (IT services), cost centre 4200. Reverse-charge not applicable, German VAT 19 %.
You brief it like a bookkeeper, not a document collector.
Instead of stopping at capture and export, you write guidelines in plain language. Cortena follows the briefing, applies judgement on edge cases, 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. GetMyInvoices facts we keep to what is publicly documented, and mark the rest "varies".
GetMyInvoices is a capable product and its exact behaviour depends on plan and connected portals. 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.
GetMyInvoices is the better fit when
- Your main pain is logging into supplier portals to download invoices.
- Coding and posting already work well in DATEV with your Steuerberater.
- You want a collector that feeds several bookkeeping tools, not an AP agent.
Cortena is the better fit when
- You want coding done for you, with a reason on every field.
- Email and e-invoice intake matter more than portal scraping.
- You run several entities and want workflows to inherit.
- You want free white-glove setup and the official DATEV service.
Moving from GetMyInvoices takes about 15 days.
There is no ledger migration to dread. Your books stay in DATEV 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. Keep portal fetch if you still need it for stubborn suppliers.

Questions people ask before switching.
Yes, for teams whose bottleneck is coding and approvals, not only collecting portal PDFs. GetMyInvoices remains a strong collector. Cortena is an agent that codes every field with an explainable reason and posts booking-ready entries to DATEV.
Cortena uses the official DATEV Rechnungsdatenservice 1.0 to send booking-ready entries into DATEV Unternehmen online, with the source document attached. GetMyInvoices can also hand documents and data to DATEV. The archive stays in DATEV, and Cortena works GoBD-aligned.
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 Mandanten, and a root mailbox can route invoices to the right entity automatically.
Some teams do keep a collector for stubborn portals while moving coding and approvals to Cortena. If that hybrid helps, we will map it in onboarding rather than force a rip-and-replace.
