A weak SR&ED claim and a strong one can describe the exact same year of work. The difference is whether the claim is built to hold up: clear on the uncertainty, backed by evidence that existed at the time, and costed so the numbers reconcile. That’s what SR&ED services actually do to a claim. Here’s what “strong” means in practice, and how professional support gets you there.
They strengthen a claim by turning scattered technical work into a documented, defensible, CRA-ready case. That means pinning down the technological uncertainty in each project, gathering the evidence that shows how you investigated it, and making the costs line up with that technical story. A claim that does all three survives scrutiny. A claim that does one or two of them is where refunds get reduced.
A strong claim contains a technical narrative built on uncertainty, evidence that predates the filing, and costing that reconciles with both. Miss any one and the whole thing gets shakier.
When those three agree with each other, the claim tells one coherent story. When they don’t, that’s exactly what a reviewer notices.
Because the evidence is strongest while the work is fresh. Reconstructing a claim 16 months later means guessing at time splits, half-remembering which approaches failed, and hunting for records you didn’t keep. Tracking as you go captures the uncertainty, the attempts and the hours while they’re still accurate.
This is the single biggest quality difference I see. The same company, tracked through the year, produces a claim that’s both larger and far easier to defend than the version it would have reconstructed in a panic near the deadline.
It reduces the risk by making the claim defensible before it’s ever filed, and by standing behind it if the CRA takes a closer look. Claims get reduced when the technical story is thin, when the evidence doesn’t back the narrative, or when the costs don’t reconcile. A good service closes those gaps up front, then provides audit defense if the claim is selected for review, so you’re not facing questions alone.
Consider a CCPC that qualifies for the 35% enhanced rate, with $500,000 in eligible salaries and a $100,000 arm’s-length Canadian contractor (claimable at 80%, so $80,000). That’s a qualifying base of about $580,000, and roughly $203,000 in federal credit before the prescribed-proxy overhead amount and provincial credits.
Two companies could file that identical base and get very different outcomes. The one whose narrative clearly shows the uncertainty, backed by commits and benchmarks from the time, and whose costs reconcile, is far more likely to see it accepted as filed. The one with a vague write-up and mismatched numbers is harder to defend if the CRA reviews it, and more likely to see the claim trimmed. The base was the same. The strength wasn’t. For a qualifying CCPC, that credit is refundable and paid as cash. The 35% rate applies to the first $6 million of qualifying spend, up to $2.1 million a year, and phases out with taxable capital. With provincial credits the combined return is higher than the federal credit alone, though not by simple addition, and how much higher depends on your province. Our State of SR&ED overview has more.
A strong SR&ED claim identifies a technological uncertainty, documents systematic investigation and advancement, cites contemporaneous evidence, and reconciles every claimed cost. Use this to judge the strength of a claim, yours or your provider’s, before it goes in.
SRED.ca charges a flat fee, billed monthly, never a percentage or contingency fee, which usually works out to roughly half the lifetime cost of a percentage-based firm. As far as we know, we’re the only SR&ED provider that publishes its pricing on its website. The part that matters most for claim strength: we track your eligible work year-round, so the narrative and evidence are captured while the work is fresh rather than reconstructed at the deadline. We’re CPA-owned, audit defense is included, and if the CRA approves less than 75% of the filed claim we waive our fees. If there’s no eligible work in your year, you don’t pay. You can see the terms on our pricing page.
The strength of an SR&ED claim isn’t the size of the number. It’s whether the number survives contact with a reviewer. Show what you couldn’t resolve, what you tested, and how the claimed costs connect to that work, and you have a claim that holds. If you want yours built that way from the start, grab a free consultation. The CRA’s SR&ED program page sets out what a claim has to show.

A strong claim clearly shows technological uncertainty, systematic investigation and technological advancement, backs it with evidence that existed while the work happened, and has costs that reconcile with that technical story. Strength is about defensibility, not just the dollar figure.
Both. The technical narrative has to come from the people who did the work, so a good service talks to your engineers to capture the uncertainty and the approaches, then handles the costing and filing on the finance side.
The time it takes varies, but short year-round check-ins avoid reconstructing an entire year near the deadline. Capturing the uncertainty and evidence in small increments as the work happens is quicker and more accurate than a filing-time scramble.
A stronger claim doesn’t guarantee the CRA won’t review it, but aligned evidence, narrative and costs make it much easier to defend. A well-built claim is also easier to accept as filed, because the pieces agree.
Yes, and that’s where a lot of the value is. A repeatable process keeps your claims consistent from year to year, captures work you’d otherwise forget, and builds a track record that’s easier to defend than a series of one-off filings.
The CRA asks you to support the technical and financial claims you filed. With audit defense, your provider works through those questions with you using the evidence behind the claim. This is much easier when the claim was built to be defensible in the first place.
