See our Fair use policy: https://standardledger.co/terms-conditions/ clause 3.2.3
Monthly Fees that include a transaction allowance are based on a Fair Use Policy. We monitor transaction volumes processed through Receipt Bank and Xero on a monthly basis. If, on a rolling average basis in a 3-month period your transaction volumes exceed that included for the plan you are on, we will increase your plan to the appropriate level, and reserve the right to retrospectively charge for any increases in prior months. Any changes or additional charges will be agreed in advance.
For the avoidance of doubt, in determining the number of transactions processed we will refer to the detailed “Account Transactions” report within Xero for your primary trading bank account.
