Two minutes a month is all this needs.
WHAT TO CHECK
Your current balance, and whether it meets the minimum Any pending balance and when it clears Whether anything is approaching expiry, where expiry applies Your next renewal date
WHAT TO DO
If your balance meets the minimum and a renewal is coming, redeem so the credit is there when the invoice is generated. If a balance is approaching expiry, redeem regardless. Otherwise, do nothing.
DO IT ALONGSIDE
Your monthly Client Area check: unpaid invoices, upcoming renewals, domains approaching expiry, tickets awaiting your reply.
Combining them means one habit rather than two.
ONCE A YEAR, ALSO
Check whether the programme rates or rules have changed on your dashboard Check your contact email is current so notices reach you Check you are not holding services split across two accounts
WHAT NOT TO DO
Check daily. Balances move slowly, and frequent checking produces nothing except a habit.
