Billing & finance

Billing queue and invoicing (admin)

How charges reach the queue, become invoices, get paid, and how the outstanding total is calculated.

Billing managersAdmins

The money flow, end to end

  1. 1A reservation is dispatched and flown.
  2. 2The dispatch sheet is closed out with meter readings, which queues billable items (aircraft time, and instruction time when a CFI was assigned).
  3. 3A billing manager reviews the queue, edits or adds items, and turns a member's items into an invoice.
  4. 4The invoice is reviewed, its PDF generated, and it is sent or a Stripe pay link is issued.
  5. 5Payment arrives (Stripe, or logged manually) and the invoice is marked paid.
  6. 6Instruction lines on the paid invoice become payable CFI earnings.

Everything below lives on Billing & queue (/portal/billing-dashboard): queued items sit above the invoice list on the same page.

Billable items in the queue

A billable item is one future invoice line. Items arrive automatically from dispatch closeout and dues automation, or you can add them by hand.

KindTypical source
AircraftDispatch closeout — meter hours x wet rate.
InstructionDispatch closeout when the reservation had an instructor.
DuesMonthly membership automation.
ChargebackFuel, landing fees or damage recharged to a member.
CreditA negative line reducing what the member owes.
OtherAnything else — checkouts, testing fees, materials.
Item statusMeaning
QueuedReady to be invoiced.
HeldParked — excluded from invoicing until released.
InvoicedAttached to an invoice line; locked from editing.
VoidCancelled and ignored.
  • Edit description, date, quantity and rate inline; the amount recalculates.
  • Tag the instructor on instruction items — this is what drives the CFI earning, so never leave it blank.
  • Hold an item when a squawk or dispute needs resolving first, then release it back to queued.
  • Invoiced items cannot be edited. Reopen or delete the invoice to release them.

Creating and editing invoices

  1. 1Select the queued items for a member and choose to invoice them — items are grouped per member into one draft.
  2. 2Open the draft to review it: add, edit or remove line items, adjust rates, and set the due date.
  3. 3The PDF regenerates automatically whenever the invoice changes; preview it before sending.
  4. 4Send the invoice by email, or generate a Stripe pay link to hand to the member directly.

A billing manager has full authority over the lifecycle: mark paid, record a partial or manual payment, void, reopen a sent invoice back to draft, or delete it entirely. Deleting or reopening returns its billable items to the queue.

Account credits

Credits are a prepaid balance on a member's account — use them for refunds, goodwill, promotions or deposits carried forward.

  • Grant a credit from the Account credits panel with an amount and a note explaining why.
  • Unapplied credits are consumed automatically by the next invoice issued to that member.
  • A credit can only be edited or deleted while it is still unapplied — once applied to an invoice it is locked for audit.

How the outstanding total is calculated

  • Only sent invoices count. Drafts are still being assembled and voids are cancelled, so both are excluded.
  • Outstanding is the sum of remaining balances: invoice total minus payments and applied credits.
  • Overpayments are floored at zero so they never reduce someone else's balance.
  • Queued billable items are shown separately as work-in-progress, not as outstanding receivables.
