Hi,
The comparison with PayPal isn't strictly "like for like" as Payatrader offers more payment channels than PayPal.
With Payatrader you get a FREE virtual terminal that allows customers to pay you over the phone - whereas PayPal charges £20 a month for this facility. Note, if you have a GPRS enabled tablet or iPad you can also use the virtual terminal to take a payment immediately at the customers premises - saving the cost of leasing a terminal.
Payatrader also provides a 24/7 contact centre, handy for customers that prefer not to give their card details directly to the trader, and a email/customer database facility so you can send requests for payment by email with an embedded payment link.
Payatrader rates vary from 2.3 to 2.95% depending on turnover; and, unlike PayPal a trader is automatically given the best rates. With PayPal you need to apply for it. On a per transaction basis, you will pay between £2.30 to £2.95 per £100 collected with Payatrader versus £3.60 with PayPal.
Finally, funds settled directly into your bank account and not a holding account like PP.
All this extra capability is catered for in the one-off fee - which is £74 using the CLEANITUP referral code.
Hope this helps!
