Migrate from Theurer
Move from Theurer to PeakSpitz, safely.
Moving off Theurer should feel like restoring from a backup, not a leap of faith. Your print MIS data is read into a PeakSpitz environment of your own, checked against your real numbers, and run in parallel — while Theurer keeps running, untouched, the whole time. Here is exactly how, step by step.
theurer.com C3 is an established German ERP/MIS for print and packaging, and its real strength is depth in the packaging verticals — labels, folding carton, corrugated and flexible packaging — with preconfigured business templates, mature estimating and production planning that are well localised for the German-speaking market. That depth is also why teams migrate: for a general commercial printer or a smaller SME, a packaging-grade ERP can be more system than the business needs, and it is often implemented on-premise and consultant-led. Businesses wanting a lighter, cloud, all-in-one that covers the whole company — sales, storefront, payments and everyday operations, not just the print floor — tend to move for breadth and simplicity rather than because C3 lacks depth.
The safe way to leave Theurer
Work down the list at your own pace. Nothing here is irreversible, and your current system stays live throughout.
- 1
Before you touch anything — get a backup you own
Get a copy of your data out of Theurer that you control — a file held on your side, not just a setting inside the system. Confirm in your contract that you have the right to export, and note any renewal, notice or lock-in dates so the timing stays on your terms.
- 2
Export your data
Pull customers, estimates, jobs, stock and invoices out of Theurer in the most complete format it offers — CSV, spreadsheet, or an account/API export. Take the history too, not just open items: past records, documents and contacts are worth keeping.
- 3
Send us a sample
Before you commit, send us a representative slice — a handful of customers, a few recent orders or bookings, part of your catalogue. We map it into PeakSpitz and show you the restored result, so you see exactly how your print MIS data lands before you move the rest.
- 4
See what maps to what
We line Theurer up against PeakSpitz: customers, estimates, jobs, stock and invoices become customers, catalogue, orders, documents and ledgers in one joined-up system. Anything without an obvious home is flagged early, not discovered late.
- 5
Bring it in — a read-only restore
Your data is read into a fresh, isolated PeakSpitz environment of your own. Nothing inside Theurer is touched, changed or switched off — it keeps running exactly as it is.
- 6
Verify against your numbers
Before you trust it, reconcile the totals — balances, counts, tax and revenue — against what Theurer shows today. The numbers have to match before anything goes live.
- 7
Run both in parallel
Keep Theurer live and run PeakSpitz alongside it for as long as you like. Compare like for like, move one area across first, and build trust before you depend on it. No big-bang cutover, and no deadline from us.
- 8
Cross over and decommission — on your terms
Switch over only when PeakSpitz has earned it. Keep your Theurer export archived as a safety net, and close the old subscription when you are ready — not a moment before.

What to watch when leaving Theurer
- ⚠
German localisation and GoBD compliance are a genuine C3 strength, and that has a consequence at migration: your GoBD-compliant financial and archival records, and any legal retention duties, stay with your accountant. Export closed invoices and ledgers for the record rather than migrating them as live postings, and confirm your PeakSpitz VAT setup matches your German requirements before cutover.
- ⚠
Packaging estimating is a configuration decision, not an import. C3's calculation cases — board and film calcs, die-cutting, multi-up imposition, waste — are re-expressed as PeakSpitz configuration; rebuild the rate card and validate representative jobs, especially anything with heavy converting.
- ⚠
Substrate units of measure need care. Packaging materials are commonly stocked by area or weight, sometimes by reel, so map each stock unit to a PeakSpitz stock item unit deliberately rather than assuming sheets.
- ⚠
Open Aufträge mid-production need a cutover rule, and prepress stays put. Decide which jobs finish in C3 and which are re-created; imposition, repro and any label inspection/workflow files remain in their prepress tools — the MIS move is the business records.
Common questions about leaving Theurer
We do folding carton and labels — can PeakSpitz replace a packaging ERP like C3?
Credit C3 first: its packaging-specific estimating and business templates are genuinely deep. PeakSpitz is broader and lighter — one all-in-one for the whole business (sales, storefront, operations, inventory, real accounting with VAT, and payments). Shops doing heavy die-cutting or converting estimation should validate their calculation cases carefully during the rebuild.
Our books are GoBD-compliant in C3 — what happens to that?
German accounting and its archival duties stay with your accountant. PeakSpitz has real accounting with VAT built in for going forward, EU-hosted with a full audit trail; export your C3 financial history and keep it read-only per your retention obligations.
Is our data kept in the EU?
Yes — PeakSpitz is EU-hosted with per-customer data isolation and a full audit trail (GDPR-ready). Most businesses are live in about a week without consultants, versus the typically consultant-led rollout of a packaging-grade ERP.
