Paymill and Your Online Shop: Safe Payment Made Easy

Online shopping has gone mainstream. The local retail business fights for survival. Unsurprisingly, the number of online shops is increasing day by day. But beware, not all online shops are created equal. It’s not enough just taking a ready-made e-commerce software and waiting for some customers to come. You need to think about some success metrics first. Sure enough, you need to neatly arrange your products and to create a meaningful user experience and navigation. But most of all, you need to get the trust of your customers. It begins with offering safe payment methods to make the visitors feel comfortable. Considering that online shopping has increasingly turned into mobile shopping via smartphone or tablet, you need additional in-app payment tools. And some software providers need to handle subscription-based recurring payments. There are solutions from various regions in the world. Nevertheless, we decided to have a closer look at a tool made in Germany. This makes sense for everyone, not only for Germans operating German online shops. As is well known, the German e-commerce jurisdiction comes with a lot of duties and pitfalls. Thus, it is the safest way to go with a provider that is bullet-proof under these conditions also. Paymill takes on many of these worries and tackles them progressively. This should be enough reason to check them out... Paymill

What Paymill Can Do For You

1. Handling of Online Payment Transactions

Online payments made easy – that’s the claim of the online shop payment solution and software-as-a-service provider. Paymill can handle your complete payment transactions globally, enabling you to accept online payments from around the world without your customers having to leave your website. Additional to handling the payments itself, Paymill provides the complete payment and subscription parts via web forms. Furthermore, there are plugins for easily embedding and managing the solution inside the most popular online shop software tools.

2. In-App Payments for iOS and Android

Paymill’s API offers all benefits of an online payment solution and comes optimized for mobile apps. Paymill provides SDKs for Android and iOS.

3. Subscription Payments

For business models like SaaS or Cloud, Paymill offers a subscription-based option with the goal of easy handling of recurring payments. Ideally, such a tool can also help you increase customer retention and revenues by automating processes. Subscription models can be modified in accordance with different customer segments, boosting your conversion rates. With Paymill, you are also able to offer trial periods to your clients. Payments can be processed automatically on a daily, weekly, bi-weekly or monthly basis. Abwicklung von wiederkehrenden Zahlungen

Accepted Payment Methods

In essence, Paymill offers accepting the globally most popular credit cards – since credit cards are the preferred payment tool internationally, anyway. Paymill takes and processes payments all over the world, which makes for a whole lot of accepted credit cards. Especially for European retailers, Paymill also offers SEPA direct debiting. The following credit cards are supported:
  • Visa/Visa Electron/Visa Debit
  • MasterCard/Maestro/MasterCard Debit
  • Diners Club
  • Discover
  • China Union Pay (except in Croatia)
  • American Express (AMEX) (only in Germany, France, the UK, Spain, Finland, Sweden, Itay, the Netherlands, and Austria)
  • JCB (except in Croatia)
  • Card Bleue in France
  • CartaSi and Postepay in Italy
  • Dankort Debit Card in Danmark
  • 4B Visa Debit and MasterCard in Spain

PayPal: Important Payment Method Missing Here

Sure enough, it’s great to have all these credit cards supported. Nevertheless, it limits your opportunities to grow your customer base beyond those clients owning credit cards. Which not everybody does. PayPal, on the other hand, is a widely used and internationally accepted payment method. An ever-growing number of online shoppers own a PayPal account. Because it’s missing here, it would be nice if Paymill did add this option.

Supported Currencies

During initial creation and activation of your Paymill account, you set the currency of your company’s location. In all, more than 100 currencies are supported. During the activation, you can add more currencies by choosing the menu item „Payment methods“ and clicking „Yes“. As shown in the video below. Währungen hinzufügen

Payment and Accounting Processes for Retailers

For anyone using Paymill, the payments and accounting processes are without any doubt utterly important. At this point, we'll let Paymill itself have their say.

Payment Process Regarding the Retailer According to Paymill:

  • "All transactions processed using PAYMILL are settled on a weekly basis by one of our acquiring banks. The first settlement may be delayed depending on your go-live day."
  • "In order to avoid small bank transfers a minimum threshold of 100€ is setup for your weekly settlements."
  • "A negative balance invoice is generated if during one settlement cycle the volume of your credited (refunds/chargebacks) transactions exceeds the debited ones. Your merchant account will hopefully be rebalanced for the next payout cycle through your future transactions. If you have a negative balance over several settlement cycles, our acquiring bank will ask you to wire the funds in order to rebalance your merchant account."
  • "If a rolling reserve is applied to your transactions, your funds will automatically be settled with one of your weekly settlements after the given period in your contract."
  • "The percentage transaction fee will automatically be deducted from the transaction volume processed during your settlement cycle, and you will be invoiced for the fixed fee separately."

Two Types of Billings Are Provided:

  • A monthly invoice containing a total of all the fixed fee transactions
  • A weekly settlement file containing the cumulated transaction volume (transaction fees deducted)

Little Helpers: Paymill Add-Ons

2. PayButton

Paymill’s PayButton is a fast way to integrate a payment form into your website, sparing you the need to design a complete shopping cart and registering form. It’s especially well-suited for online shops with only a limited number of products (e.g., if you sell just one e-book). Integrating the button is easy. Ass soon as you click it a so-called modal window opens (like a pop-up). See the marked button in the following screenshot. Below, there’s a window with the open form.

Paymill is a well-conceived and sophisticated solution for online payments which is also kind of easy to install at the same time. The option of using a „light version“ by just installing the PayButton is a great idea – providing a secure and professional payment process even for websites with only a handful of products. It’s a pity, though, that PayPal is not one of the payment methods. This should be added since not everybody owns a credit card or wants to use it when shopping online. Other than that, it's great...
