This Move Is Not Right for Everyone
Leaving SAP for ERPNext works well for mid-sized businesses running a fraction of what they licensed. It works badly where deep industry modules are doing real work. We assess that module by module and give you the answer before you commit to anything.
50+ ERP and software projects. Zero failed projects since 2021.
The assessment is worth more than the migration
Finding out in month seven that a module has no equivalent is the expensive way to learn it.
We sell the assessment, not the outcome
The first stage is a module-by-module review marking each area as a direct fit, a partial fit that needs development, or a genuine gap with no equivalent. It is a standalone piece of work with its own deliverable, and it is designed so that a recommendation not to migrate is a perfectly acceptable result.
- Every SAP module in use assessed and rated.
- Gaps costed as development, not waved through.
- A recommendation to stay is a valid outcome.

Removing licence fees is not the whole picture
ERPNext has no per-user licensing, which is genuinely significant at scale. You still carry hosting, support, and development for anything that was standard in SAP and is not here. We model three years of total cost across both options, because a comparison that only counts the licence line is not a comparison.
- Three-year total cost, not a licence saving.
- Gap development included in the model.
- Hosting and support costed realistically.

The things that decide whether this works
These come up on every SAP assessment, and they are usually what determines the answer.
Assessment first, then a phased migration
What the project covers
Fit assessment report
Every module in use rated direct fit, partial or gap, with the evidence behind each rating.
Cost model
Three years of total cost for both options, including gap development and support.
Integration inventory
Everything currently connected to SAP, with the work to re-point each one.
Custom code review
Each custom development assessed as still needed, replaceable by standard, or obsolete.
Compliance mapping
Statutory reporting and audit requirements confirmed as satisfied before cutover.
Phased cutover plan
By entity or plant where the structure allows, with interfaces during the overlap.

SAP to ERPNext questions
Is moving from SAP to ERPNext actually realistic?
What genuinely does not carry across?
How do you get data out of SAP?
What about the licence and support savings?
Can we migrate one area at a time?
How long does an SAP migration take?

What Is Inside the Assessment and the Migration
The assessment is a standalone piece of work with its own deliverables, designed so you can decide properly. Here is what it produces, and what the migration covers if you go ahead.
From a rated fit assessment to a phased cutover
Each module rated, with the evidence attached
We work through the SAP modules you actually use, not the ones you are licensed for, which is often a much shorter list. Each is rated a direct fit, a partial fit requiring development, or a genuine gap. Anything partial or gapped carries an estimate, because a rating without a cost is not decision-grade information.
- Modules in real use identified first, by transaction volume.
- Each area rated with supporting evidence.
- Development estimated for every partial and gap.

Everything attached to SAP, and what three years really costs
We inventory every integration, interface and report that touches SAP, because each one has to be re-pointed or rebuilt and that list is always longer than expected. Alongside it comes a three-year cost model covering both options, including hosting, support and gap development rather than just a licence comparison.
- Integration and report inventory with re-point effort.
- Custom developments rated as needed, replaceable or obsolete.
- Three-year total cost for staying and for moving.

By entity where the structure allows it
Data is extracted through standard SAP tools, then transformed, because company codes, controlling areas and plants do not map directly onto ERPNext structures. Where a plant or subsidiary can move independently we phase it, with an interface covering the overlap, which removes most of the risk from a single large cutover.
- Extraction through supported SAP routes.
- Structure transformation agreed with your finance team.
- Phased cutover with interim interfaces where possible.

Everything the project delivers
Rated fit assessment
Module by module, with evidence and a development estimate for each gap.
Three-year cost model
Both options costed fully, so the decision is not made on a licence line alone.
Integration inventory
Everything touching SAP, with the effort to re-point or rebuild it.
Custom code review
Each development rated still needed, replaceable by standard, or obsolete.
Compliance mapping
Statutory reporting, audit trail and retention duties confirmed before cutover.
Phasing plan
Which entities can move independently, in what order, with what interfaces.
