Transaction fees are not paid to BigCommerce. Instead, you can integrate any compatible payment processor with the online shop and pay the fees applicable to that processor. If you use, say, PayPal on your BigCommerce site, you only pay transaction fees to PayPal.
BigCommerce has special rates for PayPal powered by Braintree (1.35%-1.75% plus A$0.30 or lower, depending on the BigCommerce plan). Conditions apply for the acceptance of this.
That being said, each Essentials subscription has a threshold for how much you are allowed to make through the online shop. On Standard, you can make up to $50k a year, on Plus it is $180k a year, and Pro includes up to $400k worth of transactions annually (all USD). If you accept more than $400k a year on Pro, you can pay an additional $150 a month per additional $200k in online sales.
The plans can be cancelled any time, although refunds cannot be made for subscription payments. There is only a contract for Pro if you have negotiated a special rate for a higher turnover or low average-order value.
All subscriptions include standard features for building and running a store online. The higher the plan, the more tools you get to grow your online sales.
There is also an Enterprise option intended for large businesses. This is completely tailored to the business, with a custom quote, contract and features suitable for large-scale online stores. It also gives you lower rates for PayPal powered by Braintree. It is the most complex of all BigCommerce plans, ideally suited for companies with an in-house developer.
There’s a no-commitment 1-month free trial without the need to register your credit card details.
