1. Method 1: Injecting the Code via the ?gutschein= Cart Endpoint
netcup’s storefront accepts a URL query parameter that writes a voucher token directly into your active PHP/Shop session cookie. Every “Redeem →” button on this site points to:
https://www.netcup.com/en/checkout/cart?gutschein=36nc17760000000gutschein is German for “voucher” (legacy links using https://www.netcup.de/bestellen/gutschein_einloesen.php?gutschein=… issue an HTTP 301 redirect to this same cart URL). Depending on the voucher type, the cart behaves in one of two ways:
- Case A (General credit voucher, e.g., €4.20 net at 0% VAT / €5.00 gross new-customer code): This is an order-level discount. The cart displays a green confirmation banner (“Voucher code has been added to your shopping cart”); pair it with any qualifying server or hosting plan (> €4.20 net at 0% VAT / > €5.00 gross) and the
- €4.20(0% VAT) or- €5.00(incl. 19% VAT) deduction line attaches automatically. - Case B (Product-bound voucher, e.g., RS 1000, RS 2000, VPS 1000): The product voucher code itself represents a complete plan package. Opening the voucher link automatically places the server plan directly into your cart with the free months or discount already applied — you do not need to add any other products, simply review and proceed straight to checkout.
2. Method 2: Manual Cart Input & Pre-Checkout Verification
Open the shopping cart directly (distinguish Product Codes vs. €5 Voucher)
Open the netcup shopping cart link (
/en/checkout/cart). Important: For any product-specific voucher code (such as RS/VPS free-month codes or Webhosting 30% off codes), simply open the cart link directly — you do not need to add any other product to the cart. Only the €5 new-customer voucher (€4.20 net at 0% VAT / €5.00 gross) needs to be paired with a regular product at checkout.Locate the Voucher / Gutschein input box in the cart
In
/en/checkout/cart, find the text field labelled Voucher (or Gutschein einlösen on the German storefront) and enter the code. Applying a product-specific code automatically places that discounted product directly into your cart (whereas the €5 new-customer voucher requires adding a regular product to the cart).Verify the promotional plan or deduction line before checkout
For a product-specific voucher, confirm that the promotional plan with its free months (e.g.
2 months free) or discount now appears directly in your cart with no duplicate items. For the €5 new-customer code paired with a regular plan, confirm the- €4.20(0% VAT) /- €5.00(incl. 19% VAT) deduction line appears below the item list.Proceed directly to checkout and confirm 0% VAT
Click Proceed to checkout to complete your order. When you select a non-EU billing country (USA, UK, Canada, China, Switzerland, Singapore, etc.) or enter a valid EU VIES VAT ID, the 19% German VAT is removed and the entire order settles at the 0% VAT net rate.
3. Invoice Accounting Logic & Effective Math by Voucher Type
netcup’s billing engine (CCP) credits the three voucher categories differently on your first and subsequent invoices (all figures below default to 0% VAT excl. tax):
| Voucher Category | Feed Example | Min. Term | Invoice Accounting Formula | Worked Example (12M) (0% VAT) |
|---|---|---|---|---|
| Free Months (N Months Free) | RS 1000 G12.5: 2 months free | 12 or 24 months | Does not extend a 12M contract to 14M; instead, it deducts N × the base monthly tariff from your initial invoice (location surcharges are not discounted). | €18.26 × (12 − 2) = €182.60 first-year total (saves €36.52) |
| Fixed Euro Credit (€ Off) | New-Customer Voucher (€4.20 at 0% VAT / €5 gross) | Any (total > €4.20 net / €5 gross) | Deducts €4.20 at 0% VAT (€5.00 gross incl. 19% DE VAT) once from your very first invoice; renewals bill at the standard rate. | VPS 500 (12M) €83.28 − €4.20 = €79.08 |
| Recurring Percentage (% Off) | Webhosting 2000: 30% off | 12 months (billed quarterly) | Reduces the base monthly tariff by 30% across every quarterly billing cycle for the life of the contract. | €3.39/mo → €2.37/mo (saves €12.20/yr) |
4. Multi-Server Orders: Why Splitting Your Cart Doubles Your Discount
netcup’s cart enforces a strict rule: maximum 1 voucher code per order, and a product free-month voucher only discounts quantity 1 of the matching server in that cart. If you are deploying two or more servers (for example, 2× RS 1000 G12.5 nodes), compare the math of a combined cart vs. split orders:
| Ordering Strategy | Cart Setup | Vouchers Applied | Total First-Year Saving (0% VAT) | Recommendation |
|---|---|---|---|---|
| Combined Single Order (Suboptimal) | Set Quantity = 2 in a single cart | 1 code total | €36.52 | The second server bills at 100% list price with zero voucher deduction |
| Two Separate Orders (Optimal) | Order #1 with primary code; Order #2 in CCP with Backup Code #2 | 2 single-use codes | €73.04 | Product vouchers work for existing customers — submit each server as its own order |
5. Complete Cart Error Reference & Fixes
| Exact Cart Error / Symptom | Root Cause | Resolution |
|---|---|---|
Voucher code already redeemed / bereits eingelöst | Product-specific codes are single-use tokens; another buyer completed checkout with that exact string first. | Click “Backup codes (4)” below the voucher row on this site and copy code #2–#5. |
| Two servers appear in cart / Regular item shows no discount | When redeeming a product-specific voucher, you manually added a regular server from the store first. Product-specific vouchers automatically add the discounted tariff to the cart on their own — only the €5 new-customer voucher (€4.20 net at 0% VAT) should be paired with a regular store product. | Remove the regular store item from your cart, enter only the product-specific voucher in an empty cart (or click our direct cart link), and proceed directly to checkout. |
Only valid for new customers / nur für Neukunden | You entered a 36nc… €4.20 net (€5.00 gross) new-customer code while logged into an existing CCP account that has previous orders. | Use the RS / VPS free-month product code or 30% Webhosting code instead — those work for existing accounts. |
| Domains, VPS ARM or VPS Lite reject all codes | Explicitly excluded in netcup’s official voucher terms (Gutscheinbedingungen). | These lines cannot be discounted with standard vouchers; wait for Easter or Black Friday promos. |
| Entering a second code deletes the first code | The cart session only stores a single active gutschein token at a time. | Keep whichever code has the higher euro value; split multi-server purchases into separate orders. |
Minimum order value not reached | The initial contract subtotal must exceed the voucher value (€4.20 net at 0% VAT / €5.00 gross incl. 19% VAT; standard G12.5 server tiers start at €7.98 net / €9.50 gross on 1M and already clear this threshold). | Ensure an eligible server or Webhosting plan whose initial invoice exceeds €4.20 net (€5.00 gross) is in the cart. |
