Which plan is best for me?

For occasional use or if you are not sure how much you will use the service pay-as-you-go credits offer a offer a simple, no-obligation option. You can upgrade to a subscription at any time.

For regular use, subscriptions work out cheaper than pay-as-you-go and avoid the need to top up at unpredictable times. You can also pay for a year in advance with a single transaction rather than making multiple payments.

For groups and businesses, subscriptions offer the advantage of shared resources so you do not need to worry about which individual uploads a particular document.

As well as the Group and Business plans that can be set up on-line, we can provide tailored solutions for any size group at $9.95 per person per month. Please get in touch with your requirements.
