Where billing lives
Go to Settings → Subscription → Membership to see your Billing & plans — your current plan and whether it's active.
From here you manage your subscription and the card your plan is billed to.
Note: This is your Fieldsity subscription billing — separate from SityPay, which is how you collect payments from your clients. See Set up SityPay to accept card payments.
