Can I switch between PAYG and a monthly subscription?

Both models can coexist — you can have an active subscription and a PAYG balance at the same time. Common paths:

• Start PAYG, subscribe later. Use your free credits and a couple of PAYG packs to validate the workflow, then subscribe once usage stabilizes.
• Subscribe, add PAYG top-ups. Monthly plan covers steady usage; PAYG covers occasional spikes.
• Cancel a subscription, go PAYG-only. Keep buying packs as needed; no recurring charges.

Existing credits don't move during any of these switches. Monthly credits expire at renewal/cancellation as usual; PAYG stays forever.
