Montonio + WooCommerce in Estonia: How to Accept Payments in Your Online Store
A single Montonio module covers 80% of Estonian purchases via bank links — SEB, Swedbank, LHV, Coop and Luminor — plus card payments, Apple Pay, Google Pay, BNPL and shipping to Omniva/SmartPost parcel lockers. No separate plugins or subscriptions.

Context: how Estonian e-commerce payments actually work in 2026
Before choosing a gateway, it helps to understand the structure of online payments in Estonia — it’s quite specific and differs from what you’ve likely seen in other markets.
- Bank links (pangalingid) — about 80% of all online payments. Estonian customers habitually open their SEB, Swedbank, LHV, Luminor, Coop, or Liisi ID account and pay directly. Without bank-link support, your e-commerce conversion drops dramatically.
- Cards — the remaining ~20%. Most of that is Apple Pay and Google Pay (mobile wallets); traditional Visa/Mastercard entry is used less and less.
- Currency is EUR. Multi-currency is only needed if you have substantial export volume (FI, DE, US, UK).
- VAT (käibemaks) + e-invoice. Correct KMS rates, e-invoice generation for Maksuamet (Estonian Tax Board), GDPR cookie consent — the gateway doesn’t handle these directly but shouldn’t get in the way.
From this perspective, a “universal international gateway” (Stripe, PayPal, Adyen directly) is not enough on its own for the Estonian market — there are simply no bank links. You need either a local gateway (Montonio / Maksekeskus / EveryPay) or a combination: “local gateway for bank links + Stripe for cards from international customers.”
This is especially relevant for e-Residency founders running a WooCommerce store on an Estonian OÜ: even if your company is registered remotely, if your customers buy from Estonia they expect bank links. Skipping that is the most common reason e-Resident stores see weak conversion.
Why we put Montonio first
100 orders/month with €50 average basket — payment fees
Montonio is a relatively young Estonian payment provider (founded 2018, headquartered in Tallinn) that has become the default standard for new WooCommerce projects in Estonia in 2024–2026. Several reasons drive our first recommendation.
1. Fixed fee per transaction instead of percentage. This is the key difference from Maksekeskus, which charges roughly 1.5% + €0.25 per bank-link payment. Montonio’s fee is fixed and doesn’t depend on order size. On a real case of an average men’s clothing store (average basket €68, 200 orders/month, 80% via bank link), the annual difference is €1,000–1,500 in favor of Montonio. As the average basket grows, the gap widens linearly.
2. One module — all payment methods. The Montonio for WooCommerce plugin already includes: bank links SEB / Swedbank / LHV / Coop / Luminor / Liisi ID, card payments through Adyen, Apple Pay, Google Pay, Revolut Pay, plus Pay Later (BNPL). No need to install three plugins and complete three KYC processes.
3. Modern one-page checkout. The buyer doesn’t get redirected to a separate bank page with 2008-era design — everything happens in one clear dialog. A/B-measured Montonio checkout conversion runs 5–12% higher on average than the classic Maksekeskus + bank-links combo.
4. Fast onboarding. Registration + KYC takes 1–2 business days. Maksekeskus and especially EveryPay (via bank acquiring) can stretch to 1–2 weeks.
5. Logistics in the same module. Montonio Shipping adds Omniva / SmartPost / DPD parcel locker selection to the checkout — without a separate plugin or subscription. For most Estonian stores this covers 90% of the shipping requirement.
6. Free WooCommerce plugin. The official plugin lives in the WordPress.org repository, maintained by the Montonio team with regular updates.

When to choose something else
Montonio isn’t a silver bullet. In three scenarios it makes sense to look at alternatives.
Maksekeskus / MakeCommerce — for very small stores and legacy projects
If you have a very small store (fewer than ~20–30 transactions per month) or you’ve been working with Maksekeskus for years and have integrated invoicing, reports, and e-arve — switching may not pay off. Maksekeskus also has historical recognition with Estonian banks and some accountants find it easier to verify transactions in bank statements.
Downsides: ~1.5% + €0.25 per bank-link payment, plus €10/month for cards — margin suffers as volume grows.
Stripe — for international stores
If 70–80% of your traffic and orders come from the US, UK, or Western Europe, and local bank links cover only 10–15% of revenue — the combination Stripe (cards + Apple/Google Pay) + Montonio for bank links only gives the best mix. Stripe wins on international card processing, subscriptions, and platform scenarios. But Stripe does not cover Estonian bank links — that’s critical.
EveryPay — for LHV / Swedbank acquiring customers
EveryPay belongs to the AS LHV Pank group and is often sold together with a merchant acquiring contract. If you already have an acquiring agreement with LHV or Swedbank, EveryPay can turn out cheapest thanks to the integrated tariff. Suits stores with established banking relationships that don’t need Montonio’s “universality.”
Downsides: slower onboarding (1–2 weeks via bank), weaker checkout UX, no built-in shipping.
Montonio + WooCommerce — step-by-step setup
Below is the real checklist we use on every new project. A mid-skilled developer needs 2–3 hours of active work (plus KYC waiting time).
Step 1. Register with Montonio
Open the partner link iweb.ee → Montonio. Enter your legal entity (OÜ or sole trader), VAT number (if any), banking details, owner / beneficial owner. Upload documents: Business Register extract (Äriregister), owner’s ID. If standard KYC passes automatically, the account activates within 1 business day. Manual verification takes 2–3 days.
Step 2. Install the plugin
In the WordPress admin: Plugins → Add New, search for “Montonio for WooCommerce”. Install the official plugin by Montonio OÜ and activate. The plugin is compatible with WooCommerce 6+ and WordPress 6+.
Step 3. API keys
In the partner console (partner.montonio.com): Stores → Your store → API keys. Generate an Access Key + Secret Key pair. Copy them into WooCommerce: WooCommerce → Settings → Payments → Montonio. Save.
Step 4. Enable payment methods
In the same settings screen, enable the methods you need: Bank Payments (bank links), Card Payments, Apple Pay, Google Pay, Pay Later, Blik (if you sell to Poland). Each method has its own toggle. For bank links you can choose the order banks appear in the checkout.
Step 5. Sandbox testing
In the partner console switch to Test mode, then enable the matching checkbox in WooCommerce. Place a test order. Montonio provides test credentials for each bank and test card numbers. Verify: correct prices, order status updates correctly, customer confirmation email is sent.
Step 6. Production switch
Once tests pass: switch the partner console to Live, update the API keys (Live ≠ Sandbox), disable Test mode in WooCommerce. Make one real payment for a small amount (€0.50–1.00) using your own card to confirm funds reach the business bank account.
Step 7. Settlement and payouts
By default Montonio settles to your bank account the next business day (T+1). In the partner console you can configure frequency, account details, and reports for accounting. All transactions can be exported to CSV for import into Merit Aktiva, SmartAccounts, or Directo.
Pre-launch checklist
The payment gateway is just one part. Before opening sales, verify:
- “Shipping & Payments” page describing supported methods and timelines.
- “Returns & Exchanges” page (Estonian Consumer Protection Act requires 14 days).
- GDPR cookie consent and privacy policy.
- Tüüptingimused (Terms & Conditions) — mandatory for any Estonia-registered e-store.
- Customer email notifications (order confirmation, payment status, shipment).
- One real test order through each bank link you’ve enabled.
- Configured backup (we recommend UpdraftPlus + external storage).
Common mistakes
- Not enabling Apple Pay and Google Pay. It’s free with Montonio and adds 8–15% to mobile checkout conversion. Often forgotten.
- Leaving sandbox keys in production. Orders process as “test,” money doesn’t arrive. Verify Live mode is on in both Montonio and WooCommerce.
- Webhook URL not configured. Without webhooks, the WooCommerce order can stay “Pending” even after successful payment. The plugin sets webhooks automatically, but in non-standard configurations (subdir, multisite) verify manually.
- Checkout too long. Montonio’s one-page checkout is already short, but if you add 12 form fields on top — gateway savings are lost to UX friction. Keep it minimal: name, email, phone, shipping address.
Frequently asked questions about Montonio and WooCommerce
How much does Montonio cost for a small Estonian store?
Fixed fee per transaction plus an activation fee. For a micro-store with 30 orders/month and €40 average basket, it’s typically cheaper than or comparable to Maksekeskus. As basket value and volume grow, Montonio becomes significantly cheaper. See current pricing in the partner console at signup.
Do I need to be an Estonian resident to use Montonio?
No. Montonio works with legal entities in Estonia, Finland, Latvia, Lithuania, and Poland. For an Estonian OÜ (including e-Residency companies) Montonio works out of the box. The main requirement is real business activity and a SEPA-capable bank account at an EU bank.
Can I use Montonio and Stripe at the same time?
Yes. WooCommerce supports multiple active payment gateways. A typical setup for an Estonia-based store with international audience: Montonio for bank links and local cards, Stripe (or PayPal) for foreign cards and subscriptions. The customer sees both options at checkout.
What about VAT (KMS) and Maksuamet reporting?
Montonio doesn’t calculate VAT — that’s WooCommerce + your accountant. The gateway only passes the amount and returns the payment status. All transactions export to CSV/Excel for import into Merit Aktiva / SmartAccounts / Directo. If your store is registered as a VAT payer, verify that products have correct rates 22% / 9% / 0%.
How long does a complete integration take from scratch?
Assuming a ready WooCommerce site: 2–3 hours of technical work + 1–2 business days for KYC = your store accepts real payments by day three or four. If the site isn’t built yet, add 2–4 weeks for store development.
What about refunds and chargebacks?
Refunds are issued directly from the WooCommerce admin — the “Refund” button returns money to the customer through Montonio (minus a small refund-operation fee). Chargebacks (disputed card payments) go through the partner console as a separate process, typically 30–60 days; Montonio provides tools to submit proof of delivery.
