BILLING
Billing questions
- Do I need a card to start?
- No. The 14-day trial is genuinely free — no card, no charge. Add payment details only if you decide to continue.
- What happens when the trial ends?
- Nothing posts to a card automatically. We'll let you know the trial is ending; you choose a plan and add payment details to carry on. If you do nothing, the account simply pauses.
- Can I cancel anytime?
- Yes. Cancel whenever you like from your account — you keep access until the end of the period you've already paid for, then it stops. No notice period, no lock-in.
- Do you give refunds?
- The free trial means you only ever pay once you've decided it's worth it. We don't refund part-used months (standard for monthly SaaS), but you can cancel before the next renewal at any time.
- Can I switch between Solo and Practice?
- Yes — move up to Practice when you take on more contractor clients, or back down. Changes apply from your next billing cycle.
