We recommend heading to your “Connect Suppliers” page to ensure your FirstVet account is still connected properly. If it seems to be connected, it is possible that your pricing may be disabled on your Firstvet account. This means that although your credentials are correct, First Vet has disabled showing pricing for your account.
We would recommend contacting your representative at First Vet to enable online prices. Once it is re-enabled, please contact us and we will reactivate your First Vet account on Vetcove!
