Mark Sign alternative in Lithuania: Tvarka Sign

Mark Sign (UAB Mark ID) is a Lithuanian signing platform with subscription plans. The essential difference from Tvarka Sign is the pricing logic: plans with signature bundles and user limits versus paying only for signings actually performed.

What you would pay: three worked examples

Three typical cases, calculated at the public prices of both services on 2026-09-13. All amounts exclude VAT.

Situation Mark Sign Tvarka Sign
A private person, 10 documents a month with the ID card On Startui 3 signatures are free; the rest must be bought in extra-signature packs at €0.65–0.85 per signature, or on the Profesionalui plan: EUR 72 a year EUR 0 – 10 signatures a month free in the Tvarka Sign app, with no account and no monthly fee of any kind
One manager, 8 contracts a month (96 signatures a year) The Profesionalui plan: €6 a month paid upfront, which is EUR 72 a year (EUR 84 a year paid monthly) 8 × €0.29 = €2.32 a month, which is about EUR 28 a year with Smart-ID or Mobile-ID; with an ID card or USB token (30% cheaper) about EUR 19 a year
Three signers (manager, accountant, deputy), 30 signatures a month in total The Komandai plan (1–3 users, 40 signatures): €18 a month paid upfront, which is EUR 216 a year (EUR 252 a year paid monthly) 30 × €0.29 = €8.70 a month, which is about EUR 104 a year; with a card or USB token about EUR 73 a year. The three seats cost nothing

Unused Mark Sign plan signatures do not carry over to the next month. In Tvarka Sign a failed signing attempt costs nothing, and you pay for signatures only when they happen.

When to choose Tvarka Sign

  • Your signing volume fluctuates – three one month, thirty the next – and you do not want to pay for an unused bundle.
  • A team signs: the accountant, a deputy, representatives – with no user limits and no pricier plan just because of the number of seats.
  • You need batch signing in one action, an ADOC wizard for public institutions, or automatic archival PDF/A.
  • You want to sign with your ID card without a reader – by tapping the card on your phone; for personal use 10 signatures a month are free.
  • You are connecting signing to your own system through an API and want to pay per signature only – no configuration fee and no monthly minimum.

How to switch from Mark Sign

  1. Download every signed document from Mark Sign (PDF, ASiC-E or ADOC). The signature is part of the file, so it stays valid without a Mark Sign account.
  2. Sign in to Tvarka with your electronic signature. The Manager grants access to the people who sign – with no seat fees and no user limits.
  3. Upload the signed documents to Tvarka Sign: the signatures are verified on upload, and a signed PDF can take further signatures.
  4. If you used the Mark Sign API, move the integration to the Tvarka Sign API: instead of an iFrame window the signer receives a link to the Tvarka ceremony or confirms Smart-ID or Mobile-ID from your application with no redirect, and the sandbox runs without payments.
