Home / Custom ERP & SAP migration
Leaving SAP? Build the ERP you’d have designed yourself.
Custom ERP development and SAP-to-custom ERP migration for manufacturers, distributors and multi-site organisations. No per-user licences. No forced upgrades. Your process, your code.
The 2027 decision
SAP ECC mainstream maintenance ends 31 December 2027. Three doors.
Door 1
Pay to stay on ECC
Extended maintenance to 2030 at an extra fee. Buys time; doesn’t fix anything.
Door 2
Re-implement on S/4HANA
A new implementation in practice, often on a RISE subscription, with “clean core” limits on customisation.
Door 3
Own your ERP
Rebuild only what you use as a custom ERP, migrate your data, and switch SAP off module by module.
Custom ERP vs SAP S/4HANA
An honest comparison. SAP is the right answer for some global enterprises. For a growing mid-market business, it often isn’t.
| SAP S/4HANA (RISE) | Custom ERP by CodeDaddy | |
|---|---|---|
| Licensing | Subscription priced by users and scope | No per-user licence. You pay to build and to support. |
| Fit to process | Adopt SAP standard processes; extensions kept outside the core | Built around how your plant, warehouse and finance team actually work |
| Ownership | Vendor platform and roadmap | Source code and data are yours; host on-premise or any cloud |
| Upgrades | On the vendor’s release cycle | When you decide, for features you need |
| India compliance | Localisation packages and partners | GST, e-invoicing, e-way bill and TDS designed in from day one |
| AI | Vendor AI features, typically licensed separately | Document AI, copilot and agents built on your own data |
| Trade-off | Large ecosystem and partner pool | You depend on a smaller team — so we hand over code, docs and a support SLA |

SAP migration method
No big-bang cutover.
We switch SAP off one area at a time, with both systems running side by side until your team signs off. Historical SAP data stays searchable in an archive.
- 01Usage audit
Map transactions, Z-programs, reports and interfaces you really use.
- 02Blueprint & cost
Module plan, data model and a fixed price per phase.
- 03Build & integrate
Core modules first, connected to SAP so nothing breaks in between.
- 04Data migration & parallel run
Masters and open transactions cleansed, moved and reconciled.
- 05Cutover & decommission
SAP retired area by area; licences dropped as you go.
Every ERP we build is AI-ready: invoices read themselves, and managers ask the system questions in plain English.

When does SAP ECC support end?
SAP ECC 6.0 mainstream maintenance ends on 31 December 2027. Customers on EHP6 or later can buy extended maintenance until the end of 2030 at an additional fee.
Isn’t custom ERP riskier than SAP?
The risk moves from licence lock-in to delivery. We reduce it with phased go-lives, parallel runs, full code handover and documented support terms.
What happens to 10+ years of SAP history?
Open items migrate; history goes to a read-only archive your auditors can search.
How long does an SAP exit take?
It depends on modules and data volume. The free assessment gives you a phased timeline and a fixed price for each phase.
We’re on SAP Business One or Tally — is this for us?
Yes. The same approach works for any system you’ve outgrown.
