The verdict in three sentences
Moving 400 business customers to a monthly subscription in Toronto costs between CAD 22,000 and 60,000 of development in 2026 (about USD 16,000 to 44,000), plus 0.5 to 0.8% of billed revenue for Stripe Billing or Chargebee. Pre-authorized debit (PAD) combined with automated dunning brings bad debt below 2%, compared with 5 to 8% when customers pay invoices by cheque or wire. The project pays back in 10 to 14 months once the average basket exceeds CAD 200 per customer per month.
What a B2B subscription platform costs in 2026
An office supplies distributor moving to subscriptions has to fund three building blocks: the recurring billing engine, the customer portal and the accounting integration. The figures below are 2026 orders of magnitude for Ontario SMB projects.
| Item | 2026 range | Comment |
|---|---|---|
| Stripe Billing | 0.7% of billed revenue (order of magnitude) | No fixed fee, fully variable |
| Chargebee | 0.5 to 0.75% of revenue, fixed tier above a threshold | Stronger on complex billing rules |
| PAD debit fees (Stripe ACSS) | about 1% + CAD 0.40, capped at CAD 5 | Added on top of the billing tool |
| Customer portal (invoices, payment methods, plans) | CAD 9,000 to 22,000 | White label, company accounts |
| Billing rules (tiers, proration, volume discounts) | CAD 7,500 to 18,000 | The most underestimated item |
| Accounting integration (QuickBooks, Sage, NetSuite) | CAD 4,500 to 15,000 | Journal export and reconciliation |
| Dunning setup | CAD 1,500 to 4,500 | Scenarios per customer segment |
| Maintenance and updates | CAD 450 to 1,300 per month | Depends on the number of plans |
The total therefore lands between CAD 22,000 and 60,000. The gap depends mostly on pricing complexity: three fixed plans stay at the low end, while usage-based pricing with volume discounts and mid-month proration pushes toward the top.
Stripe Billing, Chargebee or an in-house engine
The tool choice drives variable cost over several years. For CAD 1.44 million of annual recurring revenue, the cost gap between tools is modest. The real difference lies in rule flexibility and connectors.
| Criterion | Stripe Billing | Chargebee | In-house engine |
|---|---|---|---|
| Fixed monthly cost | CAD 0 | CAD 0 to 850 depending on tier | CAD 0 |
| Variable cost on CAD 1.44M revenue | about CAD 10,000 per year | CAD 7,200 to 10,800 per year | CAD 0 |
| Initial development | CAD 22,000 to 45,000 | CAD 27,000 to 52,000 | CAD 90,000 to 180,000 |
| Pre-authorized debit | Native | Through a gateway (Stripe, GoCardless) | Build it yourself |
| Proration and plan changes | Native | Native, finer grained | Code and test it |
| Time to launch | 6 to 10 weeks | 8 to 12 weeks | 5 to 8 months |
| Vendor lock-in | High | High | Low |
For a Toronto SMB with 400 customers, Stripe Billing is usually the best starting point. Chargebee becomes relevant above 1,500 subscribers or when contracts mix flat fees, usage and annual commitments. An in-house engine only makes sense for a very specific model.
Pre-authorized debit and dunning: where bad debt is decided
The payment method weighs more on cash flow than the tool itself. Under Payments Canada Rule H1, a business PAD gives the payer only 10 business days to dispute a debit, versus 90 calendar days for a personal PAD.
| Payment method | Bad debt (order of magnitude) | Collection delay | Unit cost |
|---|---|---|---|
| Invoice paid by wire or EFT | 5 to 8% | 38 to 55 days | CAD 0 |
| Recurring credit card | 2 to 4% (expired cards) | 2 days | 2.9% + CAD 0.30 |
| Personal PAD | 1.5 to 3% | 3 to 5 days | about 1% + CAD 0.40 |
| Business PAD | 0.5 to 1.5% | 3 to 5 days | about 1% + CAD 0.40, capped |
| Cheque | 4 to 7% | 20 to 40 days | Manual processing |
A standard dunning sequence includes a reminder 3 days before, an email the day after a failure, a retry at day 5 and account suspension at day 12 with a call from sales. This scenario usually recovers 60 to 75% of failed debits with no human involvement.
On the reporting side, the dashboard should show monthly recurring revenue, monthly churn (aim below 1.5% in B2B), customer lifetime value and outstanding receivables.

Mini case study
Mark, owner of an office supplies distributor in Mississauga, serves 400 business customers with an average basket of CAD 300 per month, i.e. CAD 1.44 million of annual revenue. Customers currently pay by wire or cheque and 6% of amounts end up seriously late or in collections, CAD 86,400 per year.
After switching to subscriptions with business PAD, bad debt falls to 1.8%, CAD 25,920: a gain of CAD 60,480 per year. His bookkeeper saves 3 days of chasing per month, about CAD 13,000 per year. On the cost side, Stripe Billing costs CAD 10,080, the 4,800 annual debits about CAD 16,300 and maintenance CAD 9,000. Net recurring gain reaches about CAD 38,100 per year. With CAD 42,000 of development, the project pays back in about 13 months.
FAQ
How long does it take to launch B2B subscriptions?
Allow 8 to 12 weeks for three plans with a customer portal and PAD. Collecting the 400 debit agreements takes another 4 to 6 weeks of customer outreach.
Does every customer need to sign a new PAD agreement?
Yes, each business must authorize the debit agreement, which can be done electronically with a confirmation notice. In practice, 70 to 85% of customers sign within the first month when follow-up is well organized.
Does Stripe Billing handle Canadian sales taxes?
Yes, Stripe Tax can compute HST at 13% for Ontario and GST/PST elsewhere, for about 0.5% per transaction. Multi-province customers need it to avoid manual errors.
What churn rate should a B2B subscription target?
A good level is below 1.5% per month, under 17% per year. Above 3% per month, the problem lies in the offer or the service, rarely in the billing tool.
Can some customers keep paying by wire?
Yes, the platform can run several payment methods in parallel. Keep wires for large accounts with purchase order procedures, usually less than 10% of the portfolio.
