7.1 Purchase of a Service or Solution
Buyers may purchase Services on JOIST Marketplace after completing registration. Services are displayed with a starting price (“Starting from”), which reflects the Provider’s base offering.
Pricing and Taxes
Customization and Contracts
If the Buyer’s requirements are not fully covered by the base Service, the Buyer may contact the Provider to request a customized package. Both parties can collaborate to build a tailored agreement by adding:
This collaborative process forms a binding Contract (as defined in Chapter 2) once both parties approve it through the platform.

7.3 Cancelations
7.3.1 Order Cancellation Policy
If a Buyer places an order for a specific service, they have 24 hours to cancel it by contacting marketplace@joistpark.eu.
After this 24-hour period, the order will be considered in progress, and all necessary actions will proceed once the Solution Provider accepts the order.
The Solution Provider reserves the right to reject any order. In such cases, the implementation will not begin. Once the Solution Provider accepts the order, implementation will commence according to the deadline mutually agreed upon between the Solution Provider and the Buyer.
7.3.2 Disputes
JOIST Marketplace facilitates communication and collaboration between Buyers and Service Providers but is not a party to their contractual agreement.
In case of a disagreement regarding a specific order, we recommend that Buyers and Providers first attempt to resolve the matter through direct communication via JOIST’s messaging tools.
If no resolution is reached and the funds are still held in escrow on the platform, either party may request assistance from JOIST’s Problem-Solving Team by contacting marketplace@joistpark.eu.
Upon such request, JOIST Marketplace team may initiate a limited review of the dispute and, at its discretion, decide on the release or refund of escrowed funds. Both parties may be required to provide supporting documentation and communication records.
JOIST Marketplace’s decision applies only to funds held in escrow and does not extend to enforcing the terms of the contract or resolving disputes after payment has been released.
7.3.3 Refund Policy
Refunds may be considered for escrowed payments only and are subject to JOIST’s internal review.
Grounds for refund may include:
-Lack of communication from the Provider within a reasonable timeframe
-Missed delivery deadlines not justified by mutual agreement
-Submission of clearly fraudulent or plagiarized material
-Delivery that materially deviates from the agreed scope
JOIST does not process refund requests for transactions outside of escrow and encourages parties to resolve such matters independently.
