Tvarka Sign

Tvarka Sign user guide

Tvarka Sign lets you upload, prepare, sign, verify and store documents, and invite other signers. Smart-ID, Mobile-ID, LT ID and USB/eID qualified electronic signatures (QES) are supported, as well as the internal Tvarka e-signature when a qualified signature is not required.

Where to use it

You can use Tvarka Sign in two ways:

  1. In the browser: https://sign.tvarka.pro/.
  2. On your computer: the Tvarka Sign Windows app.

The browser version suits working from any computer. The Windows app suits you when you want to work with a local Tvarka Sign folder, copy documents to your computer automatically, open the file location and use a USB/eID card more conveniently.

The same account can have access to several legal entities. At the top, select the correct company or organization before uploading or signing a document.

Main view

The main menu is on the left side:

  • New document ("Naujas dokumentas")
  • My documents ("Mano dokumentai")
  • Waiting for me ("Laukia manęs")
  • Waiting for others ("Laukia kitų")
  • ADOC wizard ("ADOC vedlys")
  • Merge into one PDF wizard ("Jungti į vieną PDF vedlys")
  • ASiC-E wizard ("ASiC-E vedlys")
  • Reports ("Ataskaitos")
  • Settings ("Nustatymai")

At the top you will see the legal entity selector, the product selector, the account status, the theme toggle and this month's usage counters. The counters show actual usage by signing method: USB/eID QES, Smart-ID QES, Mobile-ID QES, LT ID QES and the Tvarka e-signature.

The Windows app additionally shows the local folder status. Uploaded documents are stored in the local Tvarka Sign folder, and signed files are mirrored to the signed-documents location.

Document formats

Tvarka Sign works with these documents:

  • PDF
  • DOC, DOCX
  • ODT
  • TXT
  • PNG, JPG, JPEG
  • XLS, XLSX
  • ADOC
  • ASiC-E

Single uploaded file limit: 50 MB.

Merge-into-one-PDF task limit: 150 MB.

When you upload a non-PDF file, Tvarka may convert it to PDF or PDF/A before signing. Separate rules apply to ADOC and ASiC-E containers.

Signature types

Smart-ID QES

Use it when you have a qualified Smart-ID account. Smart-ID Basic is not a QES.

Mobile-ID QES

Use it when you have an active Mobile-ID. The phone number must be given in international format with the Lithuanian country code, e.g. +370****4567.

LT ID QES

Use it when you hold an LT ID qualified signature. Tvarka Sign shows LT ID as a separate QES method.

USB/eID card QES

Use it with a USB token or an eID card. This method requires the card or token to be available on the computer where you sign. The Windows app is the most convenient path for this flow.

Tvarka e-signature

This is the internal Tvarka signature. It is free, but it is not a qualified electronic signature. Do not use it where legislation, the other party or an institution requires a QES.

The Tvarka e-signature cannot be used for ADOC and ASiC-E documents. These formats must be signed with a QES: Smart-ID, Mobile-ID, LT ID or USB/eID.

Uploading

  1. Select the correct legal entity.
  2. Press New document.
  3. Upload a file or, in the Windows app, select a document from the local folder.
  4. Check the document title, category and preview.
  5. If the document is meant for several signers, invite them before starting the ADOC flow.

If the uploaded file is too large, Tvarka must show an error. Reduce the file or split the documents into separate parts.

Signing

  1. In the document list or on the document page, press Sign ("Pasirašyti").
  2. Select the signing method.
  3. Check the document title and the signature code.
  4. Confirm the signing on your device.
  5. Wait until Tvarka finishes recording and verifying the signature.

If signing fails, the document must not be marked as successfully signed. A visible error means the action needs to be repeated or its cause removed – it may be an expired invitation, a connection error, an unsupported format or a missing license.

Multiple signers

Tvarka Sign supports multi-signer flows.

In PDF documents, several signers can sign sequentially.

An ADOC can be signed and extended with other signers' QES signatures sequentially.

In the invitation you can specify an email address, a name and the invitation expiry date. If you do not set an expiry date, the invitation is valid for 14 days by default.

An external signer does not have to buy a separate Tvarka account just to sign the document you sent. Their QES action is attributed to the inviting legal entity's usage.

Document statuses

Use the filters in the document list:

  • Waiting for me
  • Waiting for others
  • All ("Visi")
  • Signed ("Pasirašyti")
  • Protected ("Apsaugoti")

In a row you can see the actions:

  • Preview ("Peržiūrėti")
  • Show in folder ("Rodyti aplanke")
  • Start ADOC ("Pradėti ADOC")
  • Invite to sign ("Kviesti pasirašyti")
  • Sign
  • Protect ("Apsaugoti")

Protect means the document workflow is locked against unplanned changes. It is not the same as signing the document.

ADOC wizard

The ADOC wizard prepares an ADOC container for Lithuanian institutions and other recipients that require ADOC.

Use ADOC when:

  • the recipient explicitly asks for ADOC;
  • you need a single container with the main document and attachments.

Do not use ADOC just because the document is important. If the recipient accepts a PDF with a PAdES QES, PDF is often the simpler choice.

ASiC-E wizard

ASiC-E is a container format used for certain eIDAS and cross-border flows. It should not be the default choice for an ordinary Lithuanian company contract if the other party accepts PDF or ADOC.

ASiC-E documents must be signed with a QES. The internal Tvarka e-signature is not suitable here.

Merge into one PDF

The PDF merge wizard combines several documents into one signable PDF. The total task limit is 150 MB.

Check the document order before merging. Tvarka cannot determine by itself which attachment should come first if their order matters for the meaning of the contract or for filing documents with an institution.

Teams and access

The legal entity's Manager or an administrator can manage users and their access. Tvarka Sign is not billed by the number of users. Actual usage is billed, not team size.

Internal colleagues can be given access to documents. Send external signers a signing invitation, and do not needlessly create internal team accounts for them.

Usage and payment

The Tvarka Sign pricing principle: you pay only for paid actions actually completed, not for seats in the team.

  • there is no monthly subscription for Tvarka Sign;
  • there is no per-seat fee;
  • the Tvarka e-signature is free;
  • a QES action is counted only when the signing completes successfully;
  • a failed or cancelled signing must not be counted as a successful QES signature;
  • an external signer's QES is attributed to the inviting legal entity;
  • initial use may require a payment method and an initial balance top-up;
  • regular clients may receive a monthly invoice for actual usage.

If the product screen or your contract shows a different specific price, follow the price shown on the screen or in the contract.

Reports

In the reports, check:

  • how many QES signatures were registered this month;
  • which method was used to sign;
  • which legal entity the usage is attributed to;
  • which documents are waiting for other signers;
  • which invitations are about to expire.

Use the reports to reconcile your invoice and for internal control.

Common problems

Smart-ID does not work

Check that you are using the qualified Smart-ID, not Basic. Also check the personal code and the verification code.

Mobile-ID does not work

Check the phone number in your account. It must be in the Lithuanian format. Also check that the Mobile-ID service is active with your operator.

LT ID does not work

Check that you have an active LT ID qualified signature. If Tvarka shows a service error, try again later or contact support, stating the document and the time of the error.

USB/eID does not work

Check that the card or USB token is connected to the same computer. If you use the browser, you may need Tvarka QES Bridge or other local eID software.

I cannot add an ADOC signer

Wait until the signing in progress finishes, then open the latest ADOC version and send a new invitation.

The invitation has expired

Ask the document owner to send a new invitation. The standard validity is 14 days, unless the inviter set a different date.

The document is too large

The single-file limit is 50 MB. The PDF merge task limit is 150 MB. Reduce the file or separate the attachments.

When not to use the Tvarka e-signature

Do not use the internal Tvarka e-signature when:

  • legislation requires a qualified electronic signature;
  • the other party asks for Smart-ID, Mobile-ID, LT ID, USB/eID or another QES;
  • the document is filed with an institution that requires ADOC or a QES;
  • the risk is high and strong evidentiary value may be needed later.

In those cases, use a QES.

Minimum checklist before sending a document

  1. The correct legal entity is selected.
  2. The document version is final.
  3. The right format is selected: PDF, ADOC or ASiC-E.
  4. If the ADOC is already signed, its latest version is selected.
  5. The signing method matches the recipient's requirement.
  6. After signing, the final file was downloaded or opened.
  7. If the document is important, signature validation was checked.
