The verdict in three sentences
A firm running 2,800 pay stubs a month loses most of its payroll margin chasing inputs, not calculating pay. A custom client portal, connected to the payroll software you already use and locked on a fixed cutoff date, removes most of the chasing and protects your CRA remittances and year-end slips. Plan on a 2026 ballpark of CAD 40,000 to 70,000 and 4 months of work, with payback typically inside a year.
Where the payroll bureau's time actually goes
In a mid-sized Toronto accounting firm, payroll calculation is rarely the issue. Wagepoint, Ceridian, Payworks or the firm's own payroll engine get the numbers right. The cost sits upstream: hours texted on a Sunday night, bonuses in a spreadsheet, new hires announced the day before the run, sick leave reported weeks late. Each payroll specialist spends part of every day chasing instead of reviewing.
| Payroll bureau step | Current way (email, spreadsheet) | With a custom portal |
|---|---|---|
| Collecting pay period inputs | 3 to 6 reminders per client | Automatic reminders 5 days and 1 day before cutoff |
| New hires and terminations | Paper TD1 forms or scanned PDFs | Guided form with mandatory documents |
| Leave and absences | Sent in bulk, often late | Dated entry, attachment, alert to the specialist |
| Pre-run review | Manual re-keying | Connector import, variances flagged |
| Client approval | Email exchange after the run | Time-stamped approval button |
| Records of Employment and remittances | Rushed checks at period end | Anomalies caught at entry |
| Pay stub delivery | Bulk email | Secure client vault and notification |
Across 300 small business clients, firms usually see 20 to 25% of files arrive incomplete after the cutoff. Those files drive the off-cycle runs, corrected remittances and overtime.
What the module should include, and what it should not do
The classic mistake is trying to rebuild a payroll engine. The calculation, the CRA source deductions, T4 slips and Records of Employment stay in your certified payroll tool. The custom module sits before and after it.
| Component | Role | Share of budget (2026 ballpark) |
|---|---|---|
| Multi-client portal | Inputs, hires, terminations, leave | 25 to 30% |
| Rules and validation engine | Hours consistency, caps, missing documents | 15 to 20% |
| Payroll software connector | Export in import format, stubs returned | 20 to 25% |
| Specialist dashboard | Progress per client, delays, anomalies | 10 to 15% |
| Calendar and reminders | Cutoff dates, email and SMS reminders | 5 to 10% |
| Security and privacy | Canadian hosting, role-based access, audit log | 10 to 15% |
On compliance, the firm handles sensitive data: SINs, medical leave, garnishments. Canadian data residency, encryption, strict client separation and a full audit trail are expected under PIPEDA and by most clients' insurers. With most Ontario clients on biweekly pay, a reliable cutoff matters even more than in a monthly cycle.
Toronto firms typically bill a payroll bureau service at a base fee per run plus CAD 4 to 9 per pay stub, a 2026 ballpark. The module mainly protects the margin on that volume and lets the team absorb more clients without hiring. It also gives partners a live view of which clients are late every cycle, which is useful when renegotiating fees or tightening engagement letters.
Mini case study
Priya, partner at a 22-person accounting firm in Toronto, runs a payroll team of 5 specialists serving 300 small businesses and 2,800 pay stubs a month.
- Chasing avoided: 40 hours a month at CAD 55 loaded hourly cost, or CAD 2,200 a month.
- Corrected stubs: from 3% to 1%, so 56 fewer per month at 30 minutes each, or 28 hours, worth CAD 1,540.
- Total monthly gain: CAD 3,740, or CAD 44,880 a year.
- For a module budgeted at CAD 55,000, payback lands at about 15 months on time savings alone.

The bigger upside is capacity: 68 freed hours a month let the team take on 20 to 25 more clients without a new hire, which shortens payback to well under a year.
FAQ
Do we need to switch payroll software?
No. The connector uses the import formats your payroll tool already supports. In roughly 80% of cases a standard input import exists and is enough to start.
Does the portal file remittances or T4s?
No, your certified payroll software keeps that role. The portal improves the data going in: validation at entry, mandatory documents, cutoff enforcement and alerts before the run.
How long to onboard 300 clients?
About 4 months of project time, including a 6 to 8 week pilot with 20 to 30 volunteer clients. The other 270 move over across 2 to 3 pay cycles.
Will small business owners actually use it?
Adoption usually tops 85% by month three if data entry takes under 10 minutes per run and the firm stops accepting emailed inputs after an announced date.
What should we budget for maintenance?
Plan on 10 to 15% of the initial cost per year, a 2026 ballpark, for regulatory changes, connector updates and support.
