Yearly subscription

A yearly subscription is a state: a package locked for twelve covered months, rates fixed for the term, no monthly gate, one GST invoice.

The quote

12 × the chosen package − half of the unused credit over the trailing year (the carry-forward) + any dues outstanding (cleared by the same payment). The package defaults to what the last run implied; switch to a higher band — a consultancy that tested with 10 people and runs 1,200 across clients subscribes at the 1000+ rung with its count.

During the term

Each covered month records its cycle at the locked package; growth beyond the package bills only the difference. The other half of the unused credit becomes re-run credits for the year.

Renewal

The next quote nets the term's shortfall or surplus; unused credit carries again at 50 %.
