How to set up a payment processing system

Ready to Start Making Money?

This is an exciting step! You've got your business idea, and now it's time to set things up so you can actually get paid. Choosing the right payment system makes you look professional, gives your customers a great experience, and makes sure your hard-earned money lands safely in your bank account. Let's break down how to do it.

First, How Will You Be Selling?

The right system for you depends entirely on whether you're selling face-to-face, online, or a bit of both.

1. For In-Person Sales (At markets, in a shop, or on the go)

If you're selling directly to customers, you'll need a card reader. These are small, simple devices that connect to your smartphone or tablet and let you take chip & PIN, contactless, and mobile payments (like Apple Pay or Google Pay). The main players in the UK for small businesses are:

• SumUp
• Zettle (by PayPal)
• Square

They all work in a similar way: you buy the card reader (which is usually a small one-off cost), and then you pay a small percentage fee for every transaction you process. There are generally no monthly fees, which is brilliant when you're just starting out.

What to Compare

• Card Reader Cost: How much is the physical machine? Look out for introductory offers.
• Transaction Fee: This is the most important part. It's usually a flat percentage, like 1.69% or 1.75%.
• Payout Speed: How long does it take for the money to arrive in your bank account? (Usually 1-3 business days).

2. For Online Sales (On your website or via email)

If you're selling through a website, you need an online 'payment gateway'. This is the secure service that handles the customer's card details and processes the payment. The most popular choices are:

• Stripe: Incredibly popular and powerful. It's known for being easy for developers to integrate, but it also works out-of-the-box with most website builders like Squarespace, Wix, and WordPress.
• PayPal: A household name that many customers know and trust. It allows customers to pay with their PayPal balance or a card.

Most website platforms have these built-in. For example, if you set up a Shopify or Squarespace store, you'll just need to 'activate' Stripe or PayPal in the settings by creating an account with them.

What to Compare

• Transaction Fee: Again, this is key. Fees can sometimes be different for UK cards versus international cards.
• Integration: How easily does it connect with your website? Most modern platforms make this very simple.
• Customer Experience: Is the checkout process smooth? A trusted name like Stripe or PayPal gives customers confidence.

Your Step-by-Step Guide to Getting Set Up

1. Choose Your Path: Decide if you're selling in-person, online, or both. If you're doing both, you might find that one provider (like Square or Zettle) can handle both sides for you.
2. Research the Fees: Visit the websites for SumUp, Zettle, Stripe, and PayPal. Look for their UK pricing pages. A small difference in percentage really adds up over hundreds of sales.
3. Sign Up: Choose your provider and create an account. You'll need to provide details about your business (like your business name and address) and yourself. This is part of their legal security checks.
4. Order Your Reader (if needed): If you're taking payments in person, order your card reader. It'll be delivered to you in a few days.
5. Connect Your Business Bank Account: This is vital. During setup, you will be asked to link the business bank account where you want your payments to be sent.
6. Do a Test Run: Before you serve your first real customer, make a small test payment using your own personal debit card. Pay for a 50p item. This lets you see the whole process from the customer's side and check that the money appears in your account correctly. It's the best way to feel confident!

Top Tips for Taking Payments

• Factor fees into your pricing: Remember that if you sell something for £10, you won't receive the full £10. Make sure your prices account for the small percentage you'll pay in fees.
• Make it easy for customers: Offer the payment methods people expect. Being able to take contactless and mobile payments is no longer a bonus – it's a must-have for most businesses.
• Keep records: Your payment provider will give you a dashboard with a record of all your sales. This is brilliant for your bookkeeping and for seeing what's selling well.

And that's it! By setting up a reliable payment system, you're removing the final barrier between your brilliant product or service and a happy, paying customer. You're officially open for business.
