When the Asset Does Not Exist Yet: Istisna' Finance for German Businesses
Germany's Islamic contract finance covers works that still have to be built, manufactured or performed, such as construction measures or catering orders, using istisna' or related sale contracts so that payment follows real production rather than an interest-bearing construction or project loan.

How istisna' and parallel istisna' work
Istisna' is a sale of something to be manufactured or built according to a precise specification. The buyer and the maker agree on price, specification and delivery date in advance, and payment may be made upfront, in stages or after completion.
For financing, banks use parallel istisna'. The bank agrees to deliver the finished work to its client under one istisna' and commissions a contractor to produce it under a second, separate contract. The bank's profit is the difference between the two prices.
Why this is acceptable without interest
Classical jurists made istisna' an exception to the rule against selling non-existent goods, because people need things made to order. The bank carries real contractual obligations towards both sides, including the risk that the contractor fails to deliver on time.
German contract law: the Werkvertrag
German law offers a close equivalent in the contract for work (Werkvertrag) under section 631 BGB. The contractor must produce the promised work, and the customer must pay the agreed remuneration. The work can be making or changing a thing, or another result.
Instalment payments according to progress are common in German practice, and construction contracts often refer to the VOB/B standard terms. Islamic structures must fit these rules, for example by aligning stage payments in the parallel contract with acceptance (Abnahme) of each completed section.
Supervision and tax angles
When a bank finances a customer's payment obligations, the activity falls under German banking supervision. Section 1 of the Banking Act (KWG) defines credit business, and any provider must hold a licence granted through the ECB and BaFin procedure.
What is actually available in Germany
KT Bank AG in Frankfurt offers a WerkFinanzierung Business for goods and services linked to contracts for work under section 631 BGB. Its own examples are financing a catering service, including ingredients, and financing construction measures.
The product page does not name istisna' or any other contract structure and publishes no amounts, terms or security requirements. It describes short- to long-term financing in the text and short- to medium-term terms in its benefit list, so tenor must be clarified directly.
Related KT Bank products
Goods that are not tied to a contract for work are financed through other lines: machinery and plant through InvestitionsFinanzierung, and materials or merchandise through BetriebsmittelFinanzierung. KT Bank refers customers explicitly to these alternatives when the WerkFinanzierung does not fit.
Public and conventional routes
Contractors in Germany typically rely on house-bank guarantee lines, advance payment guarantees and KfW or state promotional loans for larger projects. All lending elements in these routes are interest-bearing; guarantee commissions alone are treated more leniently by many scholars.
Where the gaps are
There is no Islamic construction-finance provider in Germany for large commercial developments, and no published istisna' product for manufacturers. Major projects usually need Gulf or Turkish Islamic banks, with German-law contracts drafted carefully to reflect the istisna' logic.
Step-by-step: financing a contract for work
The process below outlines a typical case where a German company commissions a work, such as a building measure or custom production, and finances the contractor's price through an Islamic bank.
- Define the work precisely: specification, drawings, quantities, completion date and acceptance criteria.
- Obtain a fixed-price offer from the contractor, ideally with a payment plan by milestones.
- Present the offer, company accounts and liquidity plan to the Islamic bank.
- Agree the structure: parallel istisna', agency purchase or another form the bank's Sharia opinion covers.
- Sign the financing contract and the contract for work in the agreed order.
- The bank pays the contractor in stages after each confirmed acceptance.
- Formally accept the finished work and repay the bank under the agreed schedule.
Costs and documents
Contract finance costs depend on project risk and duration. The table shows the typical elements without implying rates that the bank does not publish.
| Item | What to expect | Note |
|---|---|---|
| Profit margin | Difference between the two contract prices | Fixed when contracts are signed |
| Guarantees | Performance or advance payment guarantees | Often required from the contractor |
| Insurance | Construction all-risk or liability cover | For building measures |
| Fees | Possible processing fee | Not published by KT Bank |
| Documents | Contract for work, specification, accounts, BWA | Building permit where relevant |
Common mistakes and refusal reasons
Contract finance is more complex than buying a finished asset because the bank depends on a third party's performance. Applications often fail on these points.
- Vague specifications that make istisna' and acceptance impossible to document.
- Paying the contractor directly before the bank's contracts are in place.
- Unrealistic completion dates without penalty or guarantee mechanisms.
- Missing building permits or approvals for construction measures.
- Projects whose use fails Sharia screening, such as bars or gambling venues.
Is KT Bank's WerkFinanzierung an istisna'?
The bank does not say so publicly. The product targets contracts for work, which corresponds to istisna' in subject matter, but the exact Islamic structure and the scholarly opinion covering it should be requested before signing.
Can a contractor finance its own costs Islamically?
A contractor needing materials for an order can use goods murabaha, such as KT Bank's working capital line, to buy inputs. Some Islamic banks also use salam or istisna' with the contractor as seller, but no such product is advertised in Germany.
What happens if the work is delayed?
Under istisna' the maker bears responsibility for timely delivery. In the parallel structure the bank can claim against the contractor, and contractual penalties for delay are generally permitted in istisna' by many scholars, unlike late-payment penalties on debts.
Does the bank own the building during construction?
Under German property law a building becomes part of the land, so ownership follows the land owner. Parallel istisna' for real estate therefore needs careful drafting, often with the client owning the plot and the bank's rights secured by contract and land charge.
Can service contracts be financed this way?
KT Bank's catering example shows that services combined with goods can be covered. Pure services without any tangible component are harder to structure under istisna', so ijara of services or other contracts may be proposed by the bank.
