The math behind a quiet April

Tax-season risk isn't hypothetical

Filing deadlines don't move. The published numbers behind what an outage or a breach costs a firm that cannot afford one in April:

$0MAverage financial-sector breachIBM Cost of a Data Breach 2026
$0KMedian ransom paymentCoveware by Veeam, Q2 2026
0 daysTo identify and contain a breachIBM 2026, Canadian average
0%Canadian businesses hit in a yearStatistics Canada, 2023
$0Credit monitoring, per client, monthlyEquifax / TransUnion Canada list price
A week in late April

The IT failures that quietly become late filings

Most April incidents don't start at midnight on the 30th. They build over the week — and a 20-minute outage in the wrong window is a CRA letter four months later.

Filing-window risk

A single missed e-filing window costs more than a year of managed IT — and the CRA review three months later doesn't forget where it came from.

Each row below is a real, observed April pattern — and the lost time is only the visible part. The client-trust hit and the reassessment risk both dwarf the IT line.

CRA & PIPEDA alignment

The four obligations we evidence by default

Compliance is the standard build — not a quarterly project. Each managed accounting firm gets the same control posture mapped to s.230 ITA, PIPEDA, and underwriter expectations.

s.230 ITA

Digital Record-Keeping

Records produced in original electronic format with access logs, retention, and tamper evidence — meets CRA digital record-keeping rules under s.230 of the Income Tax Act.

CRA Folio S15-F2
PIPEDA

Client Privacy

Encryption at rest and in transit, PII never in ticket bodies, masked screen captures, least-privilege engineer access. Breach response documented and rehearsed.

OPC guidance + DPA on file
CYBER

Insurance Readiness

MFA, EDR, immutable backups — the three controls every insurer asks about — supplied with the evidence packet your broker needs. No chasing screenshots in March.

Broker-ready evidence
AUDIT

Audit-Ready Posture

Tax-season escalation queue, verified backups before Feb 1, retention schedule mapped to your engagement letter, and quarterly evidence reviews — audit posture is a state, not a project.

Quarterly evidence review
Practice systems we run in production

CRA evidence vault

Eight controls orbiting every client ledger

The standard build wraps every client record in eight overlapping controls — so an audit letter, a contractor offboarding, or a vendor incident doesn't move your IP or your filings.

Eight controls · always on

What sits on top of your client records

Client-data flow

From intake to archive — every hop evidenced

Five hops. Five controls. A client file moves from secure intake through encrypted storage, partner review, CRA filing, and into an immutable archive — with the control that protected it labelled at every step.

The rollout posted as a ledger — every entry adds to your compliance balance. By Day 45 the books are clean, the broker has bound the renewal, and the CRA evidence packet sits ready in the archive.

Changing providers

Switching is the part nobody explains

The objection is almost never whether this is worth doing. It is what happens to a practice in filing season while it is being done. So, plainly:

  • No destructive changes in the first 30 days.Discovery and stabilisation only. Nothing is migrated while we are still learning what you run.
  • No cutovers during February through May.The calendar decides the schedule, not us. Work moves rather than the deadline.
  • No gap between providers.We run in parallel with the outgoing one through the handover, and we will talk to them directly so you are not the go-between.
  1. Week 1

    Nothing changes yet

    We inventory what you run, map who has access to what, and get read-only visibility. No migrations, no cutovers, no password resets. The current provider stays exactly where they are.

  2. Weeks 2–4

    The safety net goes in first

    EDR, MFA and a verified backup land before anything is moved. If the handover went badly from here, you would still be in a better position than you started — that is the point of the order.

  3. Week 4

    The keys change hands

    Tenant ownership, domain registrar, licence agreements and documentation move into accounts you own. We run parallel with the outgoing provider through this, not after it.

  4. Day 90

    You can leave

    The onboarding term ends and the agreement is month to month. Everything is documented in your tenant, so a future provider — or you — can pick it up without us.

The standard build

Ten controls, every tier

The same build runs whatever the sector. What changes is who asks you to prove it — for you that is the CRA and your underwriter. Pick any control to see what it does.

Transparent pricing

What does this actually cost?

The published per-user rate is the same for every industry. What an accounting practice adds is scope — CRA filing windows, tax-season escalation, year-end retention.

Billed per user, per month

The published rate is the same whichever industry you are in — there is no separate schedule for accounting practices. What varies is scope, not price per seat, and we confirm the tier with you on a 20-minute call before anything is signed.

Fit

Who this is not for

Three situations where we are the wrong call. Worth two minutes now rather than twenty on a call that ends the same way.

  • One accountant, one laptop, seasonal help

    The build assumes shared client files, a domain and staff who come and go. Under about four seats it is more structure than the practice has.

    Do the security basics yourself
  • You want it billed by the hour

    Managed IT is a fixed monthly per-seat fee, and it is the only way we run somebody's systems — being paid more the more things break is the wrong incentive. Hourly work exists on the help desk for a single repair; that is a fix, not a provider.

    See the break-fix menu
  • You need someone to own the CRA answer

    We evidence the controls — retention windows, who accessed which client file, backups that cannot be altered. The professional judgment stays with your practice and your regulator. Anyone selling you "CRA compliance" as a product is selling the wrong thing.

You are mid-season

Not a disqualifier for talking. We scope now and cut over in June — we do not migrate a practice between February and May, which is the whole point of the switching plan above.

Illustrative scenario

What an engagement actually looks like

A composite example rather than a client record — the profile is illustrative, and the steps are the ones we would genuinely run.

The situation

Client files on unencrypted personal laptops, no patch management, shared passwords, and a CRA review flagging the digital record-keeping. The cyber insurance broker walks away.

What we deploy

Microsoft 365 Business Premium rollout with BitLocker on every device, Intune device management, firm-wide password manager, automated patching, and PIPEDA-aligned retention.

What changes

Client files are encrypted and patched on a schedule, shared passwords are gone, and the digital record-keeping the CRA asks about is documented rather than assembled under pressure.

FAQ

Accounting IT — Common questions

From CRA digital record-keeping and PIPEDA, to QuickBooks/CaseWare/TaxCycle, to cyber-insurance evidence — the questions we get asked most.

8 results
CoverageDo you understand accounting-specific software?

Yes — QuickBooks Online, CaseWare, Profile, TaxCycle, Sage 50, and Xero are all environments we support and integrate into M365.

CoverageWhat is the tax-season escalation queue?

From February through May, accounting clients are on an extended-hours queue with priority routing for any issue blocking a filing.

CoverageWill my CRA records hold up under audit?

Yes — we configure retention, access logs, and storage so records can be produced in original format with audit trail, meeting s.230 ITA expectations.

CoverageCan you support Citrix / hosted accounting environments?

Yes. Many firms run hosted Profile or TaxCycle; we manage the M365 + endpoint side and coordinate with the hosting vendor.

SecurityHow do you handle PII / SIN exposure during ticketing?

PII is never copied into ticket bodies. Screen captures are masked. Engineer access is least-privilege and logged.

PricingWhat does this cost for an accounting practice?

Pricing is per user, per month, and it is the same published rate for every industry — see the plan comparison on /pricing. Which tier fits depends on the control set you need rather than on your sector, and we confirm it with you on a 20-minute scoping call before anything is signed. Hardware, third-party licences, and one-off projects (cabling, migrations, office moves) are quoted separately.

CoverageDo you sign DPAs and confidentiality agreements?

Yes — DPAs and engagement-specific confidentiality undertakings are part of standard onboarding.

OnboardingCan you take over from our current IT provider mid-year?

Yes — we transition outside of tax season when possible, and run parallel coverage during the handover.
