向卖家发送报价
在 Exchange 上成为商店新所有者的第一步是通过产品页面向卖家发送消息。在买家收件箱中收到卖家回复后，您可以通过点击提供报价向卖家发送报价。只有当卖家回复了您的第一条消息时，您才能提供报价。您的报价必须至少达到卖家挂牌价的 80%。
点击添加报价，然后以美元输入报价，再点击发送。如果您不想继续，则可以点击删除报价。请注意，您必须确认您有经济能力完成交易，因为不提供分期付款和部分付款选项。
如果您已发送报价，但希望取消，则可以点击取消报价。
卖家接受您的报价后，将创建 Escrow 交易。卖家根据您的报价创建 Escrow 交易之后，您会收到支付服务合作伙伴 Escrow.com 的电子邮件，其中包含交易的详细信息以及关于如何向卖家付款的说明。这就是您应该只使用 Escrow.com 进行付款的原因。
专有产品页面
创建专有产品页面的选项适用于满足特定销售阈值且希望在出售商店时保留信息的商店，这些信息包括商店名称、社交媒体账户或专有 URL 等。
您可以在专有产品页面发送消息，以直接从卖家处了解关于该商店的详细信息。
保密协议
在线购买或销售商店需要极大的信任。如果您在销售一家商店，您可能担心您商店的相关敏感信息会落入坏人之手。如果您要购买一家商店，尽职调查通常要求您深入了解商店的财务信息。
此时就会需要 NDA 或保密协议。NDA 是具有法律强制力的合同，有助于确保卖家和买家之间分享的所有机密信息都保密。这些协议具体规定了在销售期间和售后应保密的信息类型。
NDA 应指定信息的用途，以及信息不会与其他人共享或用于其自身的商业利益。
什么时候需要 NDA？
大多数情况下，大型商店的卖家必须在买家进入检验期时向买家披露机密或专有信息。此时，卖家应开始进行获得 NDA 的流程，这将由买家或可能接触到商店相关机密信息的任何他方签署。
我为何应签署 NDA？
如果您确定要在网上购买任何大型业务，卖家可能会要求您签署保密协议。这样做有助于与卖家建立信任，并允许您审查所需的信息，以便做出是否购买的最终决定。

Send the seller an offer
The first step in becoming the new owner of a business on Exchange is to message a seller from their listing. After you have a reply from the seller in your buyer inbox, you can send the seller an offer by clicking Make an offer. The ability to make an offer will only be available when the seller has responded to your first message. Your offer must be at least 80% of the seller's listing price.
Click Add offer and then type in your offer value in USD, and then click Send. You are able to click Remove offer if you do not want to proceed. Keep in mind that you must confirm that you are financially capable of completing the transaction because installments and partial payment options are not available.
If you have already sent in an offer, but want to cancel it, then you can click Cancel offer.
As soon as your offer is accepted, the seller will create the Escrow transaction. After the seller creates the Escrow transaction from your offer, you receive an email from our payment partner, Escrow.com, with the details of the transaction and instructions on how to pay the seller. Here's why you should only use Escrow.com for payments.
Private listings
The option to create a private listing is available to businesses that meet a certain sales threshold, and who want to sell their business while keeping information such as the name of the business, social media accounts, or URLs private.
You can message private listings to find out more information about the business from the seller directly.
Non-disclosure agreements
Buying or selling a business online requires a large amount of trust. If you're selling a business, you may be concerned that sensitive information about your business could get into the wrong hands. If you're buying a business proper due diligence often requires you to dig deep into a businesses' financials.
This is where the NDA, or Non-Disclosure Agreement, comes in. The NDA is a legally enforceable contract that can help ensure any confidential information that is shared between sellers and buyers is kept confidential. These agreements specifically outline what information should be kept private during and after the sale.
The NDA should specify what purposes the information is meant to be used for and that the information will not be shared with others or used for their own commercial advantage.
When do I need an NDA?
In many cases, sellers of larger businesses must disclose confidential or proprietary information with buyers at the point when the buyer begins their inspection. It's at this point that the seller should begin the process of obtaining an NDA, which will be signed by the buyer or any other parties who could be exposed to confidential information about the business.
Why should I sign an NDA?
If you're serious about buying any larger-scale business online, it's likely that you'll be asked by the seller to sign a non-disclosure agreement. Doing so will help establish trust with the seller and will allow you to vet the information that you require to make a final decision about buying.
