Almost every claim that runs into trouble on review runs into trouble in the same place. Not the science, and not the eligibility. The hours.
A company describes genuinely eligible work, and then cannot show how it arrived at the percentage of each person's year that was spent on it. The number was produced in June, from memory, for a period that ended in December. It may well be accurate. It is not evidence.
The CRA does not require a timekeeping system, and it does not require software. It requires that the numbers in the claim can be traced to something recorded while the work was happening. That is the entire standard, and it is met by about fifteen minutes a week.
The sheet is a record-keeping tool, not a claim. It produces the hours and the evidence trail; the eligibility judgment and the allocation method still have to be made by someone who knows the program.
The sheet is easy. The habit is the hard part, and it fails in predictable ways.
Pick a fixed time. Friday afternoon, before anything else closes out. A recurring fifteen-minute calendar block for the technical team costs nothing and is the single change that makes the difference.
One person owns it. Not everyone. One technical lead who collects the rows and enters them, asking two questions of each person: what did you try, and what happened.
Do not backfill more than a week. A log filled in monthly is a reconstruction with better handwriting. If a week is missed, note that it was missed rather than inventing it.
Keep the non-SR&ED hours in. The instinct is to log only the eligible work. That makes every technical person look like they spent 100% of the year on SR&ED, which is both untrue and one of the fastest ways to attract attention.
It does not decide eligibility. It records hours and evidence against projects; whether those projects meet the CRA's two requirements is a separate judgment, made against the facts and the current guidance.
It does not calculate a claim. There is no expenditure pool, no proxy calculation, and no credit estimate in it, deliberately. Those depend on payroll data, corporate structure, provincial rate, and assistance received, none of which belong in a sheet passed around a technical team.
It does not replace your existing systems. If your developers already log against tickets and your production team already keeps batch records, those are better evidence than any spreadsheet, because they were created for another purpose. In that case use this sheet only for the allocation layer on top, and put the ticket or batch reference in the evidence column.
The difference between a company that fills this in and one that does not shows up at exactly two moments. The first is at filing, when the technical narrative can be written from a record of what was actually tried rather than from a meeting where people try to remember. The second is on review, when the reviewer asks how the percentages were arrived at, and the answer is a file rather than an explanation.
Neither moment is dramatic. Both are worth considerably more than fifteen minutes a week.

If you are starting a fiscal year, an hour spent deciding how time and materials will be recorded is worth more than any amount of work at filing time. Bring the sheet to the call and we will set it up against your actual projects.
