Recover safely.
Share less.

Keep the result page open if it is still available, note the approximate time and step that failed, and take a screenshot that contains no COA values or access URLs. Do not upload the document again unless the page tells you to start a fresh session.

Never email a source COA, extracted values, the page's capability token, a signed storage URL, an API key, or a payment callback. CoaSift support will not ask for a raw secret.

Check that the file is an English supplier or raw-material COA in PDF, JPEG, or PNG format, no larger than 4 MiB and no more than five pages. If the result expired, the content cannot be recovered; start a fresh upload only if you still have authority to process the document.

Do not pay again. A browser return page does not prove payment, and the full result stays locked until a valid callback is verified. Record the internal order reference from your receipt, avoid sending card details, and contact support before another payment attempt.

If another tab changed the review, use the newest reloaded version and compare it with the source before retrying. If a reviewed export fails, keep the page open, confirm that every included field and row is reviewed, and retry once before contacting support.

A failed deletion message does not mean content was deleted. The original deletion deadline is unchanged. Keep the page open, retry once, and contact support if the action still fails. Do not send the content or access token in the message.

Use the founder-approved temporary inbox below. The intended coasift.com domain and puka@coasift.com inbox remain deferred. Checkout remains inactive.

Email kushtrim@promnestria.biz with the approximate time, browser, stage that failed, and a content-free order reference if payment is involved. The private service does not offer emergency or 24-hour support.
