Illustrative scenario: a Calgary bookkeeping firm running three GST/HST cadences
A Calgary bookkeeping firm serving about 60 small businesses carries three GST/HST cadences at once. Monthly and quarterly filers must file and pay one month after each period ends; most annual filers have three months after fiscal year-end. Alberta adds no provincial sales tax, so the complexity is entirely in the cadence mix.

The problem
Three reporting cadences interleave across the year, and each period-end opens a batch of returns that all share the same one-month clock. The months where cadences collide arrive as a stampede nobody planned for.
The quieter risk is drift: a quarterly filer whose taxable supplies grow into a monthly obligation keeps being worked on the old schedule until a late return makes the change obvious.
The workflow, step by step
- 1
Record each client's reporting period once
The CRA-assigned cadence becomes a property of the client's service rather than something a bookkeeper remembers each month.

- 2
Generate the work from the period-end
Each period-end opens a return project carrying the same checklist: reconciliation, input tax credit review, preparation, filing.

Colour the one-month clock
Every open return ranks by how close its filing-and-payment date sits, so the batch is ordered without anyone sorting it.

Digest to the assigned bookkeeper
Each staff member sees their own returns and their own approaching dates rather than the whole firm's list.

Watch the collision weeks
The workload view shows which weeks stack monthly, quarterly and annual work together, far enough ahead to move preparation earlier.

What this changes
Firms running mixed GST/HST cadences this way typically find the cadence is encoded once instead of recalled monthly, and that period-end becomes a planned workload rather than a recurring scramble — with a cadence change being a one-field edit rather than a habit to unlearn.
