The verdict in three sentences
In 2026, connecting your business tools to stop double entry goes either through an iPaaS (Make, Zapier, n8n) at 20-500 EUR/month, or through custom connectors at 4,000-15,000 EUR per flow. iPaaS is unbeatable to start fast; custom wins on high volumes and complex logic. The main gain: -30% double entry and markedly better data reliability.
iPaaS or custom: the costs in Toronto
One flow = a sync between two tools (e.g. a new CRM client creates the accounting record). iPaaS bills per operation; custom needs an upfront investment but removes the per-operation cost.
| Flow type | iPaaS (setup + /month) | Custom (per flow) | Timeline |
|---|---|---|---|
| CRM > Accounting | 1,500 EUR + 30 EUR/month | 4,000 - 7,000 EUR | 2-3 weeks |
| E-commerce > ERP | 3,000 EUR + 90 EUR/month | 8,000 - 12,000 EUR | 3-5 weeks |
| Form > CRM | 800 EUR + 20 EUR/month | 4,000 - 6,000 EUR | 2 weeks |
| ERP > BI | 3,500 EUR + 120 EUR/month | 9,000 - 15,000 EUR | 4-6 weeks |
| HR > Payroll | 2,500 EUR + 60 EUR/month | 7,000 - 11,000 EUR | 3-5 weeks |
Simple rule: below a few thousand operations/month, iPaaS stays cheaper. Above that, custom becomes worthwhile because the iPaaS licence climbs with volume.
The real cost: double entry and errors
Double entry costs more than time: it generates errors that are expensive to fix. Each automated flow removes an entry and makes data reliable.
| Automated flow | Entries/month removed | Hours/month saved | Error reduction |
|---|---|---|---|
| CRM > Accounting | 220 | 9 h | -85% |
| E-commerce > ERP | 600 | 18 h | -90% |
| Form > CRM | 300 | 7 h | -95% |
| ERP > BI | 150 | 12 h | -80% |
| HR > Payroll | 90 | 6 h | -88% |
Combining 3 to 4 flows, an SME easily removes 30 to 45 hours/month of re-entry and more than halves its data errors.
Mini case study
Karim, IT lead of a 60-person trading SME in Toronto, has double entry between CRM, e-commerce and ERP: 3 people spend 35 h/month on it. We set up 3 flows via Make for 6,500 EUR setup and 210 EUR/month in licences.
Gain: 32 h/month freed (at 35 EUR/h = 1,120 EUR/month = 13,440 EUR/year) and a drop in invoicing errors. Year-1 cost: 6,500 + 2,520 = 9,020 EUR for 13,440 EUR of value. Payback in 8 months, then a net gain over 10,000 EUR/year, excluding fewer client disputes.

FAQ
iPaaS or custom connector?
Below a few thousand operations/month, iPaaS (20-500 EUR/month) is cheapest and fastest. Custom (4,000-15,000 EUR/flow) becomes attractive on high volume or complex business logic.
How long to connect two tools?
2 to 6 weeks per flow depending on API availability and data mapping. A simple flow (form > CRM) can be ready in one to two weeks.
Make, Zapier or n8n?
Zapier is simplest, Make best value for power, n8n allows self-hosting (sensitive data). We choose by your volume and confidentiality constraints.
What if an API changes?
Connectors can break on an API update. That is why maintenance of 150 to 600 EUR/month is recommended to monitor and fix the flows.
Can we start small?
Yes: we often start with a single priority flow (the most painful) at 800-3,500 EUR setup, then extend once ROI is proven.
