The comparison points in this guide are compiled from Consumer Protection Law No. 6502, after-sales service practices, ISO 9001 quality management principles and sector price observations.
The seven differences may not appear at the same scale in every project. A direct meeting with the manufacturer's technical office is advised before signing.
Difference 1: price gap is typically 15-30%
Because an intermediary adds a margin on top of the resold product, the final price is typically 15-30% higher than buying directly from the manufacturer. The exact gap depends on project size and delivery conditions.
In direct sales from the manufacturer, supply and production costs are tabulated transparently. With clear cost lines, deposit and milestone schedules also become more predictable.
- Intermediary margin pushes the final price up by 15-30%.
- Manufacturer tables make cost components transparent.
- Milestone schedules become predictable.
- The gap grows as the project gets larger.
Difference 2: warranty term and scope
Manufacturer warranty covers the entire structural system; the steel frame, panels, roof, insulation and connection details are secured under one contract. Intermediary warranty is often kept within the sale and routes technical responsibility back to the manufacturer.
This structural difference defines who is liable when issues occur. With a turnkey manufacturer, a single phone call is enough; in the intermediary model, multiple parties must be contacted.
- Manufacturer warranty covers the entire structural system.
- Intermediary warranty is limited and routes responsibility upstream.
- A single point of contact saves time during warranty.
- Written warranty must be part of the contract.
Difference 3: delivery time and contractual late penalty
For manufacturers, the production schedule aligns directly with planning and a late delivery penalty can be added to the contract. With intermediaries, since production sits with a third party, delivery time can drift from initial estimates.
A contractual late penalty is legal assurance for the customer. Manufacturers can write this clause directly, while intermediaries usually have to refer to the upstream party.
- The manufacturer schedule aligns with the contract.
- Delivery time can extend unpredictably with intermediaries.
- The late penalty must be in writing.
- The penalty clause influences the deposit decision.
Difference 4: contract scope runs from a single source
In a turnkey manufacturer setup, production, transport, assembly, permit-occupancy support and warranty are gathered in one contract. With intermediaries, every line can be passed to a different party, creating coordination issues.
A single-source contract is simpler legally and faster operationally. Who solves the issue is clear, and the customer is not worn down.
- Production, transport and assembly come together in one contract.
- In the intermediary model, scopes get split.
- A single counterpart accelerates coordination.
- Less ambiguity remains during legal proceedings.
Difference 5: in-house assembly team or subcontractor?
Manufacturers usually go to site with assembly teams they have trained and worked with for a long time. Knowing the technical detail of the system, the team also performs on-site quality control.
In intermediary models, assembly is often handed to a separate subcontractor. When technical knowledge transfer is weak, structural errors or delays may surface.
- A manufacturer's in-house team masters the system's detail.
- Knowledge transfer is critical in subcontractor teams.
- On-site quality control is easier with the in-house team.
- The team's identity matters during warranty.
Difference 6: after-sales support and technical service
For manufacturers, after-sales support is a natural service. Spare parts, panel reinforcement, warranty repairs and consultation all come from the same technical office. With intermediaries, support tends to bounce between the manufacturer and the customer, lengthening the process.
Under Consumer Protection Law No. 6502, after-sales obligations rest on the manufacturer. This indirectly provides legal assurance for the customer.
- The manufacturer's technical office is a single point of support.
- In the intermediary model, support oscillates between parties.
- Legal responsibility stays with the manufacturer.
- Spare parts and panel reinforcement are faster with the manufacturer.

Frequently Asked Questions
Is buying from the manufacturer really cheaper?
Yes, direct purchase from the manufacturer typically offers a 15-30% price advantage. The intermediary margin creates this gap, and it grows with project size.
Do I lose warranty entirely if I buy from an intermediary?
Not entirely; the scope is usually limited to the sale, and technical responsibility is routed to the manufacturer when issues arise. The process therefore extends.
What does a turnkey contract guarantee?
It guarantees that production, transport, assembly, warranty and delivery time are run from one source under a single signature. This raises legal assurance for the customer.
Can a firm using a subcontractor for assembly also be good?
It can, but assembly quality depends on the subcontractor's experience and knowledge transfer. The manufacturer's in-house team usually delivers more consistent results.
Who holds legal responsibility for after-sales support?
Under Consumer Protection Law No. 6502, the manufacturer is responsible for after-sales service and spare parts supply. The intermediary does not assume this responsibility directly.
Are factory visits possible at every stage?
At AYD Prefabrik, factory visits can be scheduled at any stage by appointment. A visit before the contract and during production carries different but valuable purposes.
