Compliance products
eInvoicing for Dynamics AX. Without upgrading to D365.
Compliant eInvoicing for AX 4.0, 2009 and 2012. EN 16931 / UBL 2.1. Peppol and PDP ready. Ship in weeks, not quarters.
In short
A pre-built eInvoicing connector retrofits EN 16931 / UBL 2.1 compliance onto Dynamics AX 4.0, 2009 and 2012 — no upgrade to D365 required. It generates compliant XML from your existing invoice data, exchanges it with Peppol and certified PDP platforms such as Pagero, Basware, EDICOM and Tradeshift, and tracks the full invoice lifecycle inside AX. Modular country packs cover France, Germany, Belgium, Italy and Poland, with more on request, and the scope spans AR, AP and project invoices — inbound supplier UBL lands straight in your AP vendor invoice journals. It supports every format the French and German mandates accept — Factur-X, UBL and CII for France, XRechnung and ZUGFeRD for Germany — and handles e-reporting alongside e-invoicing. A typical pilot lands in 6 to 10 weeks with a full audit trail, and a free data-readiness check tells you where your invoice data stands before you commit to anything.

Mandates do not wait for your roadmap
France goes live for €50m+ turnover companies from September 2026. Germany’s B2B rollout is already in motion. Belgium, Poland, Romania and Italy are live or close to it. And you are still on AX.
You have probably had this conversation ten times: “We will handle it when we move to D365.” Maybe you will. But the regulator is working to a calendar, and your D365 programme is working to a business case. Those two calendars rarely agree.
A retrofit, not a replacement
A pre-built eInvoicing connector for Dynamics AX. From the invoice data you already have, it produces compliant XML, exchanges it with Peppol and certified PDP platforms, and follows every invoice through its full lifecycle without leaving AX.
No heavy middleware. No rip-and-replace. No data duplication.
How it connects
The flow runs left to right, and every arrow is bidirectional — documents go out, statuses come back:
- Dynamics AX — Sales, Free Text & Project Invoices
- E-Invoicing Connector — AX 4.0, AX 2009, AX 2012
- Certified PA — PEPPOL Accredited Platform
- Business Partners / DGFiP (Tax Authority)
You’re in the right place if…
- You run Dynamics AX 4.0, 2009 or 2012 somewhere in your group
- You have a mandate deadline in France, Germany, Belgium, Poland, Italy or another EN 16931 country
- You want a controlled bridge to compliance, not a rushed D365 programme
- Your auditors will ask awkward questions if the XML and the audit trail do not line up

Compliance is not a format problem
Most legacy eInvoicing projects go sideways for the same reason. Teams treat it as a format conversion exercise. It is not. The hard parts are data quality, exception handling, and who owns the rejections at 5pm on a Friday.
This solution is built for those realities:
- Minimal disruption to your posting and approval workflows
- Batch-friendly processing with retries and dead-letter handling
- Clear rejection feedback, in plain English, so finance can fix the invoice without opening SSMS
Six to ten weeks to pilot
- Scoping. Volumes, document types, country footprint, target operating model. Usually a week.
- Data readiness check. We flag the top rejection causes early: VAT IDs, SIRET/SIREN, address fields, mandatory tax codes. You fix the data while we build.
- Install and configure in a non-production AX environment.
- Map, validate, test. End-to-end with real invoice patterns, not synthetic samples.
- Controlled go-live with a hypercare runbook: who monitors, who fixes, who reprocesses.
- Handover to your team with documentation and a named contact for escalations.
Who is building this
Dr Dynamics is an independent Microsoft Dynamics 365 Finance and Operations consultancy based in the UK. The team includes ex-Microsoft engineers, ex-FastTrack Solution Architects, and ex-Microsoft localisation programme managers. We have worked on AX and D365 F&O projects at EY, Deloitte, Credit Suisse, Starbucks, HPE, Somerset Council and Notting Hill Genesis, among others.
We are independent, which means when we say a retrofit is the right call, we are not quietly selling you a D365 licence on the side.
How engagement works: Validate → Implement → Run
Implement from €35,000
Full implementation: configuration, platform connection, inbound AP, the validation layer, master-data checks and cutover. Typical pilot live in 6–10 weeks.
Run Support at 15% per year
Post-go-live support with a named engineer, an SLA and a monthly operational review — so the next mandate is a configuration task, not a project.

Will this delay our D365 upgrade?
No. It does the opposite. It takes the mandate deadline off your upgrade critical path, so you can scope and test D365 properly instead of racing a regulator.
We only need one country. Do we pay for all of them?
No. The solution is modular. Deploy the country packs you need.
Do you lock us in to a specific PDP or Peppol provider?
No. It works with your existing choice. If you have not chosen one yet, we will shortlist options against your volumes and geographies.
What about our auditors?
Full audit trail, generated XMLs stored against the invoice record, status history preserved. No drama.
Can you support us after go-live?
Yes. We offer a support arrangement with a named engineer, SLA, and a monthly operational review. Separate SOW.
Is there an AppSource listing?
Not for the AX connector. Dr Dynamics does publish other ISV products on AppSource. The AX retrofit is delivered as a consulting engagement with source code escrow available on request.
