Upgrade or change plan

You always pick the plan. PayBlah does not move you up when you near capacity. There is no in-app screen to edit a stored card; chargeable checkout happens on the payment provider’s hosted page.

Prerequisites

• You must be an Admin to post a plan change, pack purchase, or downgrade.
• Non-Admins can open View Plans and read Billing history.
• Self-serve tiers need a published price in your billing currency.

Change to a higher self-serve plan

1. Open Billing.
2. Press Change Plan or Compare Plans. The page heading is Compare plans.
3. Choose Monthly or Annual 2 months free. Stay on the interval you already pay — monthly↔annual is locked mid-term.
4. Read the card: active overdue invoice spaces, seats, and the six feature ticks (Email reminders & sync, API & webhooks, Payment links & portal, Promises, Advanced analytics, Approval routing & multi-entity).
5. Press Choose Starter, Choose Growth, Choose Pro or Choose Business. Enterprise is Contact us.
6. Review the Checkout quote (see below). Do not expect a card form on this page.
7. If checkout is open, press Continue to secure payment and finish on the provider page. If it is blocked, read the refuse copy — no payment is taken.

Checkout

Checkout is a quote, not a card-capture form. The heading is Checkout. Shortcuts are Back to plans and Billing.

• Billing details — company name, country and optional VAT number are shown read-only.
• Order summary — plan, monthly or annual, any proration note (“Due today is prorated…”), tax line with treatment, and Total.
• Displayed prices are ex-tax unless the summary says otherwise. Tax treatment is a mechanism for your billing country — this help page does not call any VAT position “compliant”.
• When a chargeable provider is connected, the primary button is Continue to secure payment. Card details are entered on the provider’s secure page. PayBlah never stores card numbers.
• When the provider cannot charge, the button is disabled Checkout unavailable and the page says no charge will be taken and the plan will not change.

When Checkout refuses

• Paid mid-term upgrades are temporarily unavailable. If you already have a live paid subscription, a chargeable (or provider-bound) mid-term upgrade is refused. Copy: your current plan and billing remain unchanged, and no payment was taken. A provider checkout is not opened.
• Tax not determined. Chargeable checkout is refused until the billing country or VAT evidence can be determined. Message: tax treatment is not determined; no charge will be taken and your plan will not change.
• Interval locked. Switching monthly↔annual on a live term is refused until renewal. Message: switch only at renewal — interval is locked mid-term.
• Already on that plan returns you to Compare plans.
• A zero-due upgrade with no provider-bound subscription can apply locally with: Your plan was upgraded. Nothing was due today, so no payment was taken.

Capacity is active invoice spaces. If Checkout still prints a leftover Balance chased line, ignore it as capacity — that is not how the plan is metered.

Capacity packs

Under Compare plans the heading is Capacity packs (there is no “Top up instead of upgrading” label). The subline is: add active invoice spaces without changing plan features or limiting invoice value. Maximum two active packs.

1. Confirm the billing currency is USD and the subscription status is active.
2. Press Add pack on +25 / $19, +100 / $49 or +250 / $99 (monthly, + tax where applicable).
3. Complete hosted checkout. Spaces are added only after paid provider verification.

EUR and GBP billing cannot purchase packs. The disabled button is Unavailable. PayBlah does not invent or auto-convert EUR or GBP pack prices. Packs unlock no plan features and are billed by PayBlah, separately from the payment provider your customers use.

Downgrades

1. On Compare plans, choose a strictly lower self-serve tier (same interval).
2. Checkout shows that no payment is taken for a downgrade. Press Schedule Downgrade.
3. Confirm the on-screen effective date. The current plan stays active until this billing period ends.

Existing invoices already in follow-up are grandfathered if the new limit is tighter; new eligible invoices wait for a space. Records you already created (promises, payment plans, settlements) stay readable even if creating new ones is gated on the lower tier.

What you keep

• Invoices, customers, workflows, activity and reports stay with the account.
• Safety rails stay on every tier: stop on payment or dispute; Firm and Final wait for human approval. Those rails are never an upgrade.
• Features that need a higher plan unlock only after the new entitlement is active — not when you press Choose.

Expected result

A completed hosted payment updates Billing. A refused mid-term or tax-undetermined checkout leaves the current plan unchanged and takes no payment. A scheduled downgrade shows on Billing as a pending change on the period-end date. After a trial convert, you are sent to the trial resume preview — payment does not restart sending by itself.

If something looks wrong

• Non-Admin: Only an Admin can change the plan.
• Provider not connected: honest refuse, nothing charged.
• Need a cheaper tier but pressed cancel by mistake: prefer Change Plan / Schedule Downgrade so history stays.
• Do not use test or operator payment options as a customer how-to.
