Illustrative scenario: a Hamilton firm staging manufacturing year-ends by sub-deadline
A Hamilton firm serving manufacturing SMBs carries a book where December 31 year-ends dominate. Every T2 is due six months after year-end, but the balance is generally due two months after — three for eligible CCPCs — so the real crunch lands in late winter, exactly when slip season and T1 preparation begin. The archetype's constraint is sequencing, not capacity.

The problem
A December year-end is not one deadline; it is a chain. T4 slips for shop payroll are due the last day of February, the corporate balance is generally due two months after year-end (three for eligible CCPCs), and the T2 itself files six months out, at the end of June. When the firm's list tracks only the filing date, the balance-due dates pass quietly in the busiest weeks of the year — and interest starts running even though nothing is technically late-filed yet.
Manufacturers also make the document chase heavier than the return. Capital additions sit in equipment invoices and financing agreements scattered through the client's own records, and the fixed-asset schedule cannot close until the client's bookkeeper closes. A file that looks parked is often waiting on one invoice — but a flat to-do list cannot show which files are waiting, on whom, or for how long.
The workflow, step by step
- 1
Import the corporate book with fiscal year-ends
The client list arrives by CSV with legal names, fiscal year-ends and contacts, so every December 31 corporation is on one list before the season starts rather than rediscovered file by file.
Client CRM with CSV/XLSX import
- 2
Record T2, HST and payroll work as typed services
Each corporation's obligations become typed services with a cadence and a next-due date. Annual T2s, quarterly or monthly HST filings and slip preparation each generate their own dates instead of sharing one vague 'year-end' entry.

Split each year-end into sub-deadline stages
Every corporation gets a project with separate stages for the document chase, the balance-due review and the filing itself, each with a named owner. A file waiting on an equipment invoice sits visibly in its chase stage.

Rank the whole spring by proximity
Slip deadlines, balance-due dates and filing dates all colour by closeness on one board: red when due or overdue, orange within seven days, green beyond. February stops depending on someone remembering which clock is running.

Send the team a morning digest
Each preparer receives one email listing their files in deadline order, so the balance-due reviews surface during slip season instead of after it.

What this changes
Firms in this position typically stop treating a December year-end as a single June deadline: balance-due dates and slip deadlines separate into their own visible clocks, stalled document chases age into a colour while there is still time to call the client's bookkeeper, and the T1 tail no longer collides with corporate work nobody staged.
