The speed of response is great, they are very helpful with any questions or concerns I have had in regards too my account! They make sure that everything works as intended from start up through maintenance/ upgrades etc.. Their customer service team has been fantastic!! Nothing really at this time but would be interested if anyone was looking into purchasing additional services (such an email marketing). We use their billing software which handles our invoices along side other accounting tools we utilize such Quickbooks Online & Xero Accounting Software - both excellent products overall. I like the fact that they are constantly updating their website. I have no complaints about them, but I do like that they are always trying to improve. I would like to see more features added, but that's just me. I would highly recommend using Internet Contrasts. They are a great company to work with. They are very attentive to your needs, and they are constantly working to improve their product. I have no complaints. I am very happy with their services.
