Plan: All plans. Anyone can read the meter. Only an Admin can raise the ceiling (Change Plan or a USD Add pack).
Capacity is a headcount of invoices in active management, not the amount they are worth. Pausing or disputing an invoice does not free a space.
Prerequisites
- A plan with an assigned active-invoice allowance (Starter 25, Growth 100, Pro 250, Business 500; Enterprise unlimited).
- USD capacity packs, if any, count only after paid provider verification. Maximum two packs.
Where to look
- Open Billing → Current Plan. Copy: Active invoice spaces: N of L (or unlimited).
- Open Compare plans. The usage strip says N of L active invoice spaces in use and may add how many are Waiting to Start.
- Open Settings → View plan → Plan & billing. The meter label is Active invoice spaces with N of L used.
What consumes a space
These states keep a space until the invoice closes:
- Chasing (in active follow-up)
- Paused (including a manual pause)
- Promised
- Disputed
- Part paid
Settings says it in one line: Paused, promised, disputed and part-paid invoices keep their space until the invoice closes.
What does not consume a space
- Waiting to Start — queued because the plan is full. Not-yet-due invoices are simply not enrolled yet; they are not Waiting to Start. Billing: N invoices are Waiting to Start and use no active space. Settings: waiting invoices move in automatically as spaces open, oldest overdue first.
- Paid, settled, written down, or otherwise closed — the space frees.
- Invoices that are not overdue yet, and archived invoices.
The enforced number is that concurrent count — never an overdue money total and never “balance chased.”
When you are at the ceiling
- PayBlah does not auto-upgrade or auto-charge.
- New eligible overdue invoices wait. Existing actives are not killed to punish a spike.
- To raise the ceiling, an Admin uses Change Plan or — on USD paid accounts — Add pack (+25 / $19, +100 / $49, +250 / $99, max two). EUR/GBP packs are not purchasable.
After a downgrade to a tighter limit, invoices already in follow-up stay (grandfathered); new eligible invoices wait.
Other meters (do not mix them)
- Reports show payments recorded and paid-after-reminder activity. That is not the capacity meter, and it is not proof that PayBlah caused the payment.
- Plan cards and Settings may show a Texts row. Launch is email-first. Do not plan operations around SMS quotas or overage until text is announced for your territory. See Text messaging coming later.
- PayBlah subscription invoices on Billing (PB-…) are what you pay PayBlah — not customer AR and not capacity.
Expected result
Used + waiting is understandable: used is chasing/paused/promised/disputed/part-paid; waiting is extra overdue work that has not started. The number falls only when an invoice leaves those active states.
If usage looks wrong
- Check the invoice status. A pause, promise, dispute or part-payment still occupies a space.
- Do not expect a re-import to “fix” paid status on a row that already exists — duplicates are skipped.
- If Settings and Billing disagree after a pack purchase, wait for paid provider verification; packs do not add spaces on the button click.
- Then contact Support from inside the app with the account context attached.
