Customer accepts these Purchase Terms by placing an order for Product with WelSim.

Orders placed by Customer with a reseller of WelSim are subject to terms and conditions of purchase set forth by that reseller.


Customer may place an order with WelSim:

  1. online on the WelSim Website;
  2. by email using the appropriate contact of WelSim.

Order details shall be in English. Customer can modify order details before acceptance of Customer order by WelSim by submitting a written notice to WelSim. English is the preferred language for order-related enquiries.

Any order is not binding upon WelSim until accepted by WelSim. Non-acceptance of an order may be the result of one of the following:

  1. failed payment;
  2. growing backlog or negative payment history;
  3. incomplete or incorrect order details, such as missing email address for delivery, missing Customer billing address, or a pricing or product description error, among others;
  4. ineligibility according to the order criteria (e.g. entitlement to upgrade or to certain Product purchase options restricted to particular users or purpose of use); or
  5. for any reason at the sole discretion of WelSim.


WelSim sets prices and accept payments for Products in one of the following currencies depending on Customer's country: USD. Prices in any currency are subject to change by WelSim.

WelSim accepts major debit and credit cards (collectively, "payment cards") for online orders via third-party payment gateway providers, including, but not limited to, FastSpring, Stripe, and PayPal. WelSim is not responsible for any payment failure resulting from inaccurate payment card details provided by Customer when placing an online order, any restrictions applicable to payment card by Customer's bank, or payment gateway failure.

By purchasing Product requiring regular payments on a monthly, quarterly, or annual basis ("Recurring Payments"), Customer authorizes WelSim to charge Customer's payment card automatically at the interval and in the amount selected by Customer based on the available options during the purchase process. Customer agrees that the payment card specified by Customer for Recurring Payments is, and will continue to be, an account that Customer owns or is otherwise legally authorized to use, and that Customer will maintain sufficient availability under Customer's credit card limit, or sufficient funds in the account linked to Customer's debit card, as applicable, to pay Recurring Payments. Customer can cancel Recurring Payments at any time via Customer's account prior to the next Recurring Payment due date. If Customer cancels Recurring Payments after this time, the cancellation will not take effect until the following Recurring Payment due date, and no refund or partial refund will be issued to Customer by WelSim.

WelSim only accepts purchase orders from existing corporate Customers that have no outstanding payments past due. Purchase orders can only be paid by wire transfer on net 30 days terms, unless otherwise specified on invoice issued to Customer by WelSim. Purchase orders from newly registered corporate Customers and offline orders from individual Customers are subject to advance payment by wire transfer.


WelSim ships no physical Products. Any details necessary to enable Customer to download and/or use the purchased Product will be delivered by WelSim to Customer via email to an email address provided by Customer. Customer is responsible for providing WelSim with a valid email address for delivery purposes.

WelSim will use its commercially reasonable best efforts to deliver Product purchased by Customer within 2 business days of the order acceptance. WelSim shall not be liable for any failure to deliver Product within this timeframe.

Products shall be deemed delivered to Customer on the date when WelSim sends Product or a email to the email address provided by Customer. WelSim shall not be liable for any failure to deliver Product to Customer due to non-delivery of an email message concerning Product.


Product prices do not include any national, state or local sales tax, use tax, value added tax (VAT), goods and sales tax (GST) or other tax ("Local Tax").

Notwithstanding the foregoing, WelSim remains Customer's counterparty and no other provisions of these Purchase Terms shall be affected.

If there is a possibility to issue the invoice without Local Tax, Customer is obliged to provide WelSim with a valid Local Tax number (e.g. VAT ID) or valid exemption documentation.

Customer bears the sole responsibility for any withholding tax liabilities, and no deductions shall be made by Customer from the amount payable to WelSim under any invoice.

Any correction to an invoice due to tax reasons (in particular based on the provision of Customer's Local Tax number) shall be requested by Customer by the 7th day of the month following the month when the affected invoice was issued, at the latest. WelSim reserves the right to reject any such request if received after this date.


Any refund request following the Product purchase date will be subject to prior authorization by WelSim, and acceptance of such request shall be at the sole discretion of WelSim, unless otherwise provided by applicable law.


Customer shall comply with all applicable laws and regulations with regards to: economic sanctions; export controls; import regulations; and trade embargoes (collectively "Export Control Laws"), including those of the European Union and United States (specifically the Export Administration Act of 1979 and the Export Administration Regulations ("EAR")).
