Plans give you a monthly credit allowance (Spark 500, Boost 1,500, Build 4,000) plus the platform itself. Credits refresh every billing cycle.
Top-ups are one-time credit purchases for when you need extra before your refresh, big holiday blast, sudden growth. Top-ups are available to active subscribers.
Rollover: unused plan credits roll forward up to a cap, so a quiet month isn't wasted. Top-up credits last 12 months.
You can change plans about once a month: upgrades kick in immediately (you get the credit difference right away, prorated billing), downgrades take effect at your next renewal and you keep the credits you already have.
