In both plans, you will be allocated a preset card fee determined by your average monthly card sales. In the pay-as-you-go plan, you also pay extra fees for processing and premium cards.
Notably, they state the pay-as-you-go plan is not the best option for those who consistently have high volumes of monthly transactions, or those who accept many foreign-issued or corporate cards (which impose extra fees). They also note the pay-monthly plan is not so good for those with many monthly transactions.
If electronic invoicing, phone or mail order sales are in your pipeline, the packages allow you to add a Virtual Terminal and Pay by Link for £9.95 extra a month each.
As to settlement times, it takes up to 3 days before transactions reach your bank account.
Compared to the leading mobile card readers in the UK, Worldpay’s complex pricing does not compete with the transparent, simple costs of the others. iZettle and Square both charge a simple 1.75% card fee, and SumUp 1.69%, for all cards including Amex, Diners Club and other premium or foreign cards. Their card readers typically only cost £19-£39 + VAT and have no contract , while the pay-as-you-go Worldpay Reader costs £69 + VAT + extra payment fees.
