Not so long time ago I was thinking about how to design first-rate Checkout Flow and Registration eCommerce app for iOS. Interesting, isn’t it?

So, if you want to breathe life into this idea, you need to:

  • Think about smooth registration (this will increase the number of users),

  • Collect massive base of users,

  • Provide a feedback,

  • Promote your app.

In fact, registration through the social networks like Facebook and Google is the best way to add new users in the first steps of the start-up’s product development.

What is the best tactic?


Most of the eCommerce service giants allow people to use their app anonymously. But when the person likes some product or adds it to the wish list, the service offers to sign-up. And such giants like 6pm, Asos, Amazon, Etsy iHerb ask users to sign up when he/she is trying to add something to the shopping cart.

However, a similar tactic is not always a good idea for smaller start-ups. Most of UX pattern that is used by eCommerce giants are outdated and the big companies are not always trying to adapt to the wishes of their users. On the other hand, most people'd rather prefer old and uncomfortable UX than new and unfamiliar one.

So, how to accumulate big base of users and do not scare them with sign up process at the same time? In such a point, Guest checkout is the best option for people who want to use your commerce product, make a purchase without registration.

Pros and cons:

For clients:


  • Less time. According to the statistic, about twenty-three percent of users prefer to terminate purchase if they see obligatory registration in the app.

  • There are no annoying advertising massages.

  • Do not need to enter personal information.


  • Information about your credit card and shipping address is not saved. So you have to enter the info again with each new purchase.

  • No personal product feed, so it will be harder to find new products.

For retail:


  • Doesn't lose these twenty-three percents of the customers.

  • Higher percentage of customers will complete the purchase.

  • Lower level of the interaction cost.

  • Still get some useful data like users emails.


  • Fewer product reviews.

  • Less feedbacks.

  • It’s harder to track analytics about your audience (that could be very helpful for improvements).

I do not want Guest checkout, so what to do with regular registration/checkout process?

  • Make less “fill-in” forms (ask for minimum information about contact and credit card or pay system).

  • Make a secure app (work with secure paying systems like Stripe or PayPal).

  • Text field labels must be visible (so people could check the input information).

  • Make sure that you can help customers if the error occurs (users must see error alert clearly). And if it’s happened, give a clue how to fix it.

Smooth sign-up


Do not scare the customer. Offer to register in your app carefully and give the user an opportunity to choose:

  • a new user of the community,

  • an anonymous visitor.

Moreover, show the advantages of being a new member. For example, personalized product feed, the option to buy any item in one click, individual experience. Similar features could induce a person to register in your app. And in the end, do not forget about the quality of content that plays a key role in attracting potential customers.
