E-signature platforms in Estonia 2026: how to choose the right one

Estonia is one of the few countries where a legally binding electronic signature is an ordinary, everyday way to sign. Every adult has an ID card, Smart-ID or Mobile-ID, and a signature made with any of them is a qualified electronic signature (QES) under the eIDAS regulation — equivalent to a handwritten signature across the entire European Union.

So the question is not “can I sign electronically?” but what happens to the document before and after the signature. That is where the tools differ, and that is where the money and the time actually go.

At Allkiro we build signing and document management software, so read this as an informed but interested party’s view. Every claim about another product is limited to what its own website documents — always check prices and features with the vendor directly.

Which tool is right for you

• You sign individual documents now and then → the free DigiDoc application (id.ee).
• Embedding signing into your own product via an API → Dokobit; on Allkiro’s roadmap.
• A modern signing flow for a small business → Agrello or Allkiro.
• Signing and finding the contract again afterwards — folders, roles, search inside document contents, deadlines, reminders → Allkiro.

The five criteria that decide it

1. Which eID methods are supported?

Estonia uses three signing methods: Smart-ID, Mobile-ID and the ID card. Every one of them is available in Allkiro too.

Allkiro supports Smart-ID, Smart-ID+, Mobile-ID and the ID card (Web eID), and the same Smart-ID flow works for Latvian and Lithuanian users. Smart-ID+ deserves a separate mention: you no longer type your personal identification code into a web page — the session is bound to your Smart-ID app by QR code or app-to-app instead. That closes exactly the attack vector phishers used to rely on.

Dokobit documents the widest range of eIDs, including e-Residency digital IDs and Latvia’s eParaksts — which matters if the parties you sign with are in other countries.

2. Are signed documents valid everywhere?

A digital signature only means something if it follows an agreed standard that can be checked with a trusted application.

The Estonian and Baltic standard is the ASiC-E container (an .asice / .bdoc file). It bundles the document, the signature, the signer’s certificate and a timestamp into one file that any conforming tool can validate: DigiDoc4, the European Commission’s DSS validator, or a competing platform.

Allkiro produces ASiC-E containers, as do the other Estonian tools listed here. Be more careful with international platforms: a signature that is only valid inside the vendor’s own portal is both a lock-in risk and a clearly weaker position in a dispute.

3. Parallel or sequential signing?

Most contracts fit one of two workflows:

• Parallel — everyone is invited at once and signs when they get to it. Right for a contract where the order does not matter.
• Sequential — the next signer is only invited once the previous one has signed. Right when a manager has to approve before the counterparty does, or when a board signs in a defined order.

Allkiro supports both: you set the order when sending and can change it later, and the dashboard shows whose hands the signing round is in right now. If a tool only offers a parallel flow, approval chains move back into email — the place you were trying to get them out of.

4. What happens to the contract after signing?

This is the criterion comparisons usually skip — and it is where the overlooked cost hides, in both money and time. A signed PDF in someone’s Downloads folder is not contract management.

Before choosing software, ask:

• Can I put contracts in folders and add tags?
• Does search work on the document’s contents, not just the filename?
• Does search read scanned documents (OCR)?
• Can I set a deadline and let the system chase the signer for me?
• Is there an activity log showing who did what and when?

DigiDoc answers “no” by its very nature — it is a signing client, not a management system. Dokobit is signature-centric with a strong API. Allkiro was built with exactly these questions in mind: full-text search with OCR, folders and tags, deadlines and automatic reminders, and an activity log on every document — from the Standard plan upward.

5. How does the price change as the team grows?

Per-user pricing is not optimal when ten colleagues each sign two documents a year. Volume-based pricing is not optimal when two people sign constantly. Most platforms offer only one of these models, so they do not suit everyone.

Allkiro’s price is formed from the plan — how many signatures a month and which features — and the number of seats. The figure on the pricing page is per user, so every seat you add costs the plan price the team chose. That way a person or a company can pick the plan and the seat count that fit.

Allkiro’s plans:

• Free and Mini are single-person plans. Free includes 3 signatures a month and 100 MB of document storage; Mini adds deadlines and sequential workflows, and includes 6 signatures a month and 500 MB.
• Standard lets you add up to 5 team members, use shared folders and roles, automatic reminders and full-text search with OCR; 20 signatures a month and 5 GB are included.
• Pro has no limit on team members, and includes 30 signatures a month and 500 GB of storage.
• Enterprise adds sub-teams: departments, branches or subsidiaries in one tree, up to five levels, each branch with its own members and folders.

When the monthly signature limit runs out, the document still goes out — individual signatures can be bought at a per-plan unit price.

The full list of features and prices is on our pricing page.

Is a free e-signature service enough?

Often, yes. If you sign a couple of documents a year and file them yourself, the state’s DigiDoc is free, legally sufficient and needs no account. Allkiro’s free plan and Agrello’s entry tier both work for low volume.

A paid service pays for itself the moment finding a contract costs more than signing it did — usually somewhere between “a shared drive with 100 PDFs” and “nobody is sure which version the client signed.”

Where Allkiro sits

Allkiro is an Estonian platform that combines qualified eIDAS signing with document management in one product: Smart-ID, Smart-ID+, Mobile-ID and the ID card; parallel and sequential workflows; deadlines and automatic reminders; shared team workspaces with role-based access; folders, tags and full-text search that reads document contents; reusable templates. The interface is available in Estonian, English, Latvian and Lithuanian, and data stays in the European Union.

If you sign rarely, the state’s free application is the best solution. If you are looking for a way to manage, sign and find your documents and files, that is exactly why we built Allkiro.
