+You can create a quote for a SQLBI service by following the steps below:_
+
+1) Visit our [SQLBI training](https://www.sqlbi.com/training/) or [SQLBI consulting](https://www.sqlbi.com/consulting/) pages and choose the service you want to purchase.
+
+2) Click on the **Enroll Now**, **Subscribe**, or **Add To Cart** button, depending on the service selected.<br/><img src="images/enroll-now-subscribe-add-to-cart-buttons.png" width="600" alt="Enroll Now and Add To Cart Button">
+
+3) Select the **Quote** switch close to the Order Details section. This will create a quote instead of an order.<br/><img src="images/quote-option.png" width="350" alt="Quote Option">
+
+4) Complete the **Billing Details** section with the information of the person/company that receives the quote. This can be a name and company other than who will use the service.
+
+5) If there are course extensions included in the cart, complete the **Extensions user** section with the email of the user(s) who has access to the course that you want to extend
+
+6) If there is a **License manager** section, you should select who will manage the course licenses if they are not assigned in the quote.
+
+7) In the **Additional services** section, you can select optional services to include in the quote:
+
+  - Select **Vendor enrollment** if you need our company to fill special forms to be enrolled as a vendor in your system, like register on Ariba, SAP, etc.
+
+  - Select **Additional documents** if you need additional documents like company's tax residency certificate.
+
+8) Make sure that the products in the cart and their quantities are correct.
+
+9) Make sure that the License Type is correct.
+
+10) **Agree** to the terms and conditions. The option is not binding for the quote only, because you are not purchasing nor trying any service by simply requesting a quote. We just want to make sure you understand the Terms and Conditions for the quote. <br/><img src="images/create-quote-button.png" width="420" alt="Create Quote Button">
+
+11) Click the **Create Quote** button to complete the process and receive an email with the quote. 
+
+After you complete the quote request, you will receive an email with the quote information.

+
+At SQLBI we maximize the efficiency by automating all the processes we can, trying to remove any unnecessary bureaucracy. We try to reflect this efficiency in the pricing of our services, which we try to keep as low as possible to reflect the value of the services and making sure that most of the money goes to the production and delivery of the services and not to the sales process.
+
+We believe in the maximum transparency, so **we do not have any resellers programs**. We do not have resellers discounts, and we do not provide a different way to order our products other than our website.
+
+## Common Issues with Resellers
+
+We know that there are companies that prefer to purchase through resellers, and we have made it possible for the resellers to purchase a service on behalf of a customer. However, based on our experience, a customer who purchases through a reseller will face the following issues:
+
+1. **Higher Prices**: Customers who purchase through resellers will typically pay a higher price than if they purchase directly from our website. This is because resellers need to make a profit, and they will charge a fee for their services.
+
+2. **Latency**: You can purchase a service on our websites in a few minutes, but if you purchase through a reseller, you will have to wait for the reseller to process the order and complete the payment, because the service is not available until the payment is completed. This can take several days, and in some cases, even weeks or months.
+
+3. **Renewal Issues**: Usually, resellers do not automatically renew subscriptions. Therefore, the reseller disables the automatic renewal for services like SQLBI+ and waits for a purchase order from the customer. Oftentimes, the reseller asks for a new quote at every billing cycle, even if the pricing is always available on our website. When this process goes beyond the expiration date of a license, the customer loses the access to a subscription service.
+
+We believe that these issues can be avoided by purchasing directly from our website. When you purchase directly from us, you can be sure that you are getting the best price and the fastest delivery time.
+If you have to work through a reseller for company policies or any other reasons, we suggest to consider to buy an [Enterprise bundle](https://www.sqlbi.com/training/enterprise/) which includes a  3-year billing period for SQLBI+ instead of the yearly renewal, so that you lower the friction of the process.

+
+You have several payment methods available. If you include a SQLBI+ subscription in your order, consider that SQLBI+ is a subscription with an automatic renewal according to the billing cycle you choose (every year or every 3 years for Enterprise bundles).
+
+## Credit cards and debit cards
+Credit and debit cards are always accepted and can be used for any license amount.
+
+The credit card information is securely processed by our payment provider (Stripe), and we do not store any sensitive payment information on our servers.
+
+The credit card will be used for the initial payment and for automatic renewals if you included a SQLBI+ subscription. When you pay by credit card or debit card, at every renewal cycle you receive an email with the receipt for your payment in form of a "paid invoice" that you can use for your accounting.
+
+## Invoice
+When you create an order, you can choose to pay by invoice by selecting the **Pay by Invoice / ACH / Wire Transfer** option. This payment type adds an additional fee because of the high fixed cost involved in these operations that cannot completely automated on the receiving part, plus additional fees charged by the bank for incoming transfer.
+
+In-person courses registrations are confirmed once we receive the payment. Any service is activated once we receive the payment.
+
+If you select this option for a SQLBI+ subscription, you will not be charged automatically at the end of the billing cycle. At every renewal, you will receive an invoice before the expiration date, which must be paid before the license expires.
+
+## Wire Transfer / ACH Transfer
+When you create an order, you can select **Pay by Invoice / ACH / Wire Transfer** to complete the purchase through a wire transfer or an ACH transfer. This payment type adds an additional fee because of the high fixed cost involved in these operations that cannot completely automated on the receiving part, plus additional fees charged by the bank for incoming transfer.
+
+See the [Invoice](#invoice) section for more details about activation and renewal of SQLBI+ subscriptions.
