What fees do payment providers charge?

It depends on the provider and your contract: usually a percentage or a fixed amount per transaction, sometimes a monthly fee as well. You pay these fees directly to the provider; they aren't included in our integration price. Check current rates on the provider's website, as they change.

Can we use several payment providers at once?

Yes. A common combination is a local provider for bank links plus Stripe or PayPal for customers abroad. At checkout, the customer sees one clear list of payment methods, and you can see which provider was used for each order. Each additional provider costs from €150.

What if a customer has paid but the order status hasn't changed?

This doesn't usually happen, because the provider sends the payment confirmation directly to the server, even if the customer closes the browser and never returns to the store. If the confirmation still doesn't reach the website, the payment can be checked in the provider's self-service portal, and we fix recurring integration errors under the warranty.

Can we refund a customer from the online store?

Yes, if the provider's module supports refunds. You enter the amount to refund in the order, and the money goes back to the customer by the same method they paid with. If the module doesn't support refunds, they are made in the provider's self-service portal, and you change the order status by hand.

Will card details be stored in our online store?

No. The customer enters their card details on the provider's page or in its secure window, so they never reach your server. The store keeps only the payment ID and status. In this set-up, most of the requirements of the card data security standard (PCI DSS) are handled by the provider.

Can we offer instalments or consumer credit?

Yes, if your chosen payment provider or credit company offers such a service and it can be integrated. A separate payment method then appears at checkout, and the financing decision is made by the provider or company. You agree the terms and fees with them, and we assess the integration separately.

Payment gateway integration: Paysera, Montonio, Stripe

Payment gateway integration connects a payment provider to your online store, so customers can pay by bank link, card or mobile wallet, and the order status changes automatically once payment is made. Saitai.lt sets up Paysera (a Lithuanian payment service), Montonio (a Baltic payment platform), Stripe and PayPal in WooCommerce, VirtueMart and custom online stores. Prices start at €150, with a timeline of 2–5 working days.

Who it’s for

Your online store only accepts bank transfers, and your sales manager checks the bank statement every day and marks paid orders by hand.
Customers abandon their basket because they can't pay by card or through their own bank's link.
You sell to customers abroad who are used to paying by card, Apple Pay or PayPal.
Your current payment module is no longer updated, shows errors or changes the order status incorrectly.
You want to switch payment provider or add a second one without changing your store.
You are building a new online store and want to test payments before launch, not with your first customers.

When it’s not the right fit

You only sell to businesses on deferred payment against an invoice. Then sending a pro forma invoice or invoice matters more than taking payment at checkout.
You use WooCommerce, and simply installing the provider's official plugin with the default settings is enough. You can do that yourself by following the provider's instructions.
You haven't yet signed a contract with a payment provider. The integration can be prepared in test mode, but you'll only be able to accept real payments once the provider has approved your account.

Included

What you get

Choosing a provider

We help you choose a provider based on your customers: for customers in Lithuania, bank links matter most; for customers abroad, payment cards and mobile wallets.

Module installation and settings

We install the official module or another reliable, maintained one, enter the access keys, and set the currency, the payment methods shown and their order at checkout.

Automatic order status

Once the provider confirms the payment, the order is marked as paid and the customer gets a confirmation, while failed or cancelled payments are clearly visible in the admin area.

Matching your design

We adapt the list of payment methods, with bank and card logos, to your store's design and to phone screens.

Refunds from the admin area

If the provider's module supports it, you refund the customer straight from the order, without logging in to the provider's self-service portal.

Testing in test mode

In the provider's test mode, we try out a successful, failed and cancelled payment and a refund, and after launch we make one real test payment.

Guide and a 12-month warranty

We show you where to see payment statuses and how to issue refunds. For 12 months, we fix integration bugs free of charge.

Price

How much does a payment gateway integration cost?

Price from

€150

Integrating one payment provider with your online store costs from €150: the price covers module installation, settings, matching your design and testing in test mode. When we build a new online store, payments are included in the package (one provider in the Start package, two in Business), and each additional integration costs from €150.

Prices include all taxes – no VAT is added (we are not VAT-registered). The final price depends on the project: we put it and the timeline in the contract before work starts.

Get an exact price

What the price depends on

How many payment providers and payment methods need connecting.
Whether there is an official provider module for your platform, or the integration has to be built using the provider's API (in a custom online store).
Whether the basket or payment step design needs changing.
Whether you need refunds, partial refunds or card pre-authorisation from the admin area.
Whether you sell in several currencies or several countries.
Whether payment data also has to be passed to your accounting software.

Additional costs

The payment provider's transaction fees – under your contract with the provider; you pay them directly to the provider.
You sign the contract with the provider yourself, and account approval can take a few days, so it's worth applying in advance.
Integration maintenance after the warranty, for example adapting it when the provider changes its API – under a maintenance agreement, agreed separately.

Timeline

How long does a payment gateway integration take?

A payment provider integration takes 2–5 working days from receiving the deposit and the provider's login details. For a custom online store, where there is no module and the integration is built using the provider's API, we give the timeline after assessment.

Scope	Example	Timeline
One provider with an official module	Paysera or Montonio bank links and cards in a WooCommerce store	2–3 working days
Two providers or extra settings	Montonio for customers in Lithuania and Stripe or PayPal for customers abroad, different methods by country	3–5 working days
Custom online store	integration built using the provider's API (Laravel)	after assessment

Examples

Typical projects

A store that only accepts bank transfers

Situation: For example, a home textiles online store only accepts bank transfers. The sales manager matches the bank statement against orders every day, and some customers never pay at all.
Solution: Montonio or Paysera bank links and cards at checkout: once the customer pays, the order is automatically marked as paid, and bank transfer is kept for businesses.
Result: Fewer unpaid orders and no more checking bank statements by hand.

A store selling to customers abroad

Situation: For example, a linen goods store is getting more and more orders from Germany and the USA, but customers abroad don't use Lithuanian bank links.
Solution: Alongside Paysera bank links, Stripe card payments, Apple Pay, Google Pay and PayPal are added, and payment methods are shown according to the customer's country.
Result: Convenient payment for customers abroad, without a separate store for each country.

Service bookings with a deposit

Situation: For example, a massage studio takes bookings on its website, but some clients don't turn up, and the booked time goes to waste.
Solution: A deposit is taken by Paysera or Stripe payment when booking, and the booking is confirmed only once payment is received.
Result: Fewer no-shows and deposits without manual checking.

FAQ

Frequently asked questions

Yes. You sign the contract with Paysera, Montonio, Stripe or PayPal yourself, because the money goes into your account. The provider checks your company and website – for example, your terms of sale, contact details and return policy – and once approved, issues the access keys. We can prepare the integration in test mode even before approval.
