Những gì đã lên bản chạy thật.

The audience is stored as a rule and resolved when the campaign sends, so a lead who arrives after you schedule it is included and someone who unsubscribes in between is not. Skipped recipients are shown before you send, grouped by why — no address, opted out, no consent, duplicate.

The queue was written to and never drained, so campaign mail and eSIM QR codes were recorded as sent without leaving the building. Sign-in codes were never affected — those bypass the queue by design.

"Deposit paid" instead of "deposit_paid", everywhere at once.

An invoice can only be voided before money arrives; after that the answer is a refund and a credit note, because voiding would leave a receipt pointing at nothing.

A failed order and a refunded one stay distinct, so the first question — did that cost me anything — is answered without opening the ledger.

Three templates over one block system. Point a domain at it and the certificate is handled.

A receivable projected at acceptance is a forecast, not money. Sub-agent splits are computed from what actually arrived, so you can never owe a partner out of a projection.

Student files, signed agreements, fee disclosures, complaints, surveys and training — with a manifest listing what was included and, the part that matters, what was missing.

It matches programmes from your own catalogue, rehearses the visa interview, and explains the process to parents. Every session needing a student's details checks consent first.

The I-20, the CAS, the provincial attestation letter and the CoE are separate steps that fail separately, so they are tracked separately. Editing a track leaves cases already in flight on the one they started.

Uploading is never an implicit claim that a file is genuine; verifying is a separate act by a named person.

Nothing to write on a sticky note, and nothing to hand over when someone leaves.
