You don't need an electronic signature to "move with the times". You need one because a contract that spends four days waiting on a courier freezes your invoicing and irritates the client. And at the same time — not every document needs the same kind of signature, and most companies overpay because they don't know that.
We'll treat e-signatures like any other IT decision in a small company: no marketing, no "digital transformation", no suggesting everything needs the most expensive qualified signature. Reality is simpler: the eIDAS regulation defines three levels, each has a different use, and picking the right one can slash costs and speed document turnaround by an order of magnitude.
Three levels of signature, no marketing
Simple electronic signature (SES). Clicking "I accept" in an email, a checkbox on a form, a typed name under a PDF. It has evidentiary weight in court — it is not "worthless" as vendors of pricier solutions sometimes imply. Enough for most day-to-day B2B contracts, internal policies, goods-received confirmations, or equipment handover protocols inside your company.
Advanced electronic signature (AES). A cryptographic signature uniquely tied to a person, with the ability to detect any change to the document after signing. Identity verification is stronger — usually via authorisation transfer, video ID or a trusted profile. This is the territory of platforms like Autenti, DocuSign or Signius. Enough for the vast majority of B2B and B2C contracts, acceptance protocols and annexes.
Qualified electronic signature (QES). Legally equivalent to a handwritten signature under civil law. Required only where a statute demands it explicitly: contracts requiring written form under pain of nullity (real estate transfers, certain employment terminations delivered electronically), filings to the Polish company register (KRS), tax returns signed "personally" by the board. In Poland these come from KIR (SZAFIR), Certum, CenCert, EuroCert, SimplySign (Asseco). Roughly PLN 200–400 (~EUR 50–90) per year per certificate and card.
Three levels, three different purposes. The same signature under a waste-collection contract and under a real-estate transfer would be either overkill or too weak.
Which one when
Rule of thumb: the less likely the document ends up in court, the further down you can go. In a typical 20-person company, the mix looks roughly like this.
- Orders and customer confirmations — simple (SES) is enough. Nobody goes to court over a PLN 800 cable order.
- Commercial contracts, framework agreements, annexes, NDAs — advanced (AES). This is 80% of what you sign with clients and vendors.
- Acceptance protocols, equipment handover protocols, milestone sign-offs — advanced. Strong evidentiary value in a dispute, without the ceremony of a qualified certificate.
- Employment contracts signed electronically, KRS/tax office filings, financial statements, tax forms signed on behalf of employees — qualified. No choice here.
- Sales invoices — no signature required at all (since 2005). KSeF (the Polish national e-invoicing system) handles that separately — see our dedicated post.
Owners meeting this topic for the first time often buy a qualified signature "just in case". Then they use it twice a year — for KRS. The rest of the flow would sit comfortably in a cheaper AES platform with per-document pricing.
Picking a provider
The market splits into three segments today, and most companies should pick exactly one.
AES platforms for day-to-day work. Autenti, Signius, DocuSign, Adobe Sign. Billing: subscription or a document pack. Autenti starts at a few hundred zloty a year for a ~100-signature pack — the effective cost per signature is a few zloty. Integration with email and most popular CRM/DMS systems. Sign from the browser, the client gets a link, clicks, done. This is where the vast majority of a small company's documents belong.
Qualified certificate for the board. SZAFIR, Certum, SimplySign, CenCert. Bought per person, not per company. One or two cards for the people who sign KRS, tax office and bank filings are usually enough. Cost: PLN 200–400/year plus a one-off few hundred zloty for a card reader or a cloud app. Do not buy this for every employee — it is a board-level tool.
Trusted profile / mObywatel. Free and convenient, but mostly for public administration (social security, tax office, correspondence with authorities). Rarely accepted by B2B counterparties — do not build on it.
The "one AES platform + one qualified certificate for the board" configuration covers 95% of what a 20-person company actually needs.
A real example
At one of our clients — an 18-person structural engineering firm in steel construction — the original flow ran like this. The contract and the acceptance protocol for the design package went out by courier to the investor, came back after 3–4 working days, and invoicing only kicked in once the signed original reached accounting. On any given month, roughly a dozen documents totalling PLN 200–300k in invoicing were "in limbo".
We rolled out the Autenti platform (advanced signature) for contracts and protocols, plus a single SimplySign qualified certificate for the owner — for financial statements, KRS and employment documents. Annual cost, all in: about PLN 4,800 (Autenti subscription + certificate + a small integration with their project-management system). Time from "ready to sign" to "signed" dropped on average from 3.5 days to 2.5 hours. Recovered cash flow: easy to work out yourselves.
The point — they did not buy a qualified signature for the whole office. They didn't need to. Designers sign acceptance protocols with an advanced signature; it's enough.
Wiring it into your document flow
A signature is a feature, not a system. Value shows up only when it's plugged into what you already run.
- Email and CRM. A salesperson generates a contract from a template in the CRM (populated from the customer record), sends it for signature in one click, and gets the status back on the record. No manual PDF upload/download.
- DMS or at least SharePoint. The signed document lands automatically in the right customer folder, versioned and dated. Not in somebody's inbox.
- ERP. If the acceptance protocol triggers invoicing — it should fire automatically after signing, not when someone happens to notice. Usually a webhook from the signature platform to the ERP.
- Employee onboarding. Contract, GDPR pack, internal policies — one "signing packet", one email to the new hire. No more printing 30 pages for every joiner.
Without these connections, an e-signature mainly saves you the courier. With them, it saves you several head-months a year, measured in hours rather than in euphoria.
Your plan for the next few weeks
If contracts still travel by courier in your office, tackle it in order:
- List on paper the 10 most-signed document types. Tag each with SES, AES or QES.
- Work out what your current paper flow costs monthly — courier, printing, sales time chasing signatures, invoicing delays.
- Decide: one AES platform + one qualified certificate for the board. You rarely need more.
- Wire the platform into CRM, DMS and ERP — that's where the real saving is, not in the signature itself.
- Write a one-page policy: who may sign what, at which level. Without it, in six months everyone will be clicking however they see fit.
An e-signature is not digital transformation. It's swapping a courier for a click. Done right, it can recover a dozen days of cash flow a month and shorten customer onboarding by a week. If you don't know what to buy so you don't overpay — talk to us. The first call is free and takes half an hour.
Not every document needs a qualified signature. Most of your contracts just need to stop waiting on a courier.
