Payment and service delivery
1. Scope of the service
The specific service, object, questions, list of materials, result format, price, time limit and special conditions are set out in an individual Order Invoice. Work is performed within the Contractor's competence.
Payment covers the agreed work and preparation of the result. No predetermined conclusion, outcome of a court case or decision by another person is promised.
2. Placing an order
- Send a brief description of your task to mail@svirin.work. A description of the situation is sufficient for an initial inquiry.
- After a preliminary assessment, agree the materials and their transfer method, the questions, result format, time limits and price.
- Obtain an Order Invoice with a link to the applicable version of the Public Offer and read the terms before paying.
- Make the payment expressly designated in the Order Invoice as acceptance. An inquiry or viewing the website does not constitute acceptance.
The website has no payment or material-upload form. An email link opens the visitor's email application; the visitor sends the message themselves.
3. Methods of payment
Payment is made in Russian roubles by bank transfer under the Order Invoice or by another method expressly stated in it and permitted by law. If an individual payment link from a bank or payment operator is agreed, card details are entered only on its secure page.
Availability of a particular payment method is determined when the order is placed. The website does not collect or store full card numbers, CVC/CVV or one-time codes. Do not send them by email.

4. Full and partial payment
100-percent advance payment applies by default unless the Order Invoice specifies otherwise. An acceptance payment followed by payment of the remaining price may be provided for.
A partial payment counts towards the total service price and is not a separate commission, penalty or fee for entering into the contract. Where the balance is due after notice of readiness, the result is delivered after full payment unless the Order Invoice states otherwise.
5. Payment confirmation
A fiscal receipt or other payment document is issued in the cases and manner required by law. The relevant documentation rules apply to advance payments, their offset, final settlement and refunds.
6. Start of the time limit and additional expenses
The time limit is set in the Order Invoice and calculated taking into account receipt of the required payment, sufficient materials, access to the object and mandatory approvals. If obstacles arise, the parties exchange messages and clarify how to proceed.
Laboratory tests, delivery, site visits, engagement of specialists and other additional expenses are included in the order or agreed in writing beforehand as an amount or spending limit. An unagreed price change is not assumed.
7. Delivery of the result
The result and Services Acceptance Certificate are delivered in the agreed format: electronic, paper or both. The Client determines the recipient, taking verified authority into account. Payment by a third party does not itself entitle that party to receive the confidential result.
The acceptance and comments procedure is set out in the Offer and Order Invoice. Typographical, arithmetical and other obvious technical errors made by the Contractor are corrected at no additional charge.
8. Incorrect or duplicate payment
If funds have been debited but no confirmation has been received, do not repeat the payment until the first transaction has been checked. Send the Order Invoice number, date, amount and available payment identifier to mail@svirin.work. Any overpayment is refunded after verification under the applicable procedure.
The cancellation and refund procedure is available on a separate page. The Client's mandatory rights apply regardless of the website terms.
