Custom Salesforce and ERP integration connector in Toronto: 2026 cost

The verdict in three sentences

For an SME with 35 sales reps re-keying Salesforce orders into an ERP such as Sage 100, a custom connector costs USD 11,000 to 27,000 (EUR 10,000 to 25,000) in 2026 and pays back in under a year. An iPaaS (Boomi, Make, Workato, off-the-shelf ERP connectors) starts faster but costs USD 330 to 1,650 a month and often struggles with customer-specific pricing and negotiated discounts. The real issue is not technology: it is the quality of master data (customers, items, price lists) and error handling when an order is rejected.

What the connector must synchronise

A useful connector covers four flows. Customers (created in Salesforce, account number assigned by the ERP, credit limit and hold status sent back to the CRM), items and product families, pricing (price lists, customer discounts, quantity breaks) and orders (closed opportunity in Salesforce, sales order created in the ERP, shipping and invoice status returned to the rep).

Pricing often absorbs a quarter of the budget: mid-market ERPs handle discounts by price category, customer and quantity, which generic connectors only partially reproduce.

Custom build or iPaaS: 2026 cost comparison

An iPaaS makes sense if your flows are standard and you already pay for a subscription. Once discounts, multiple warehouses or bill-of-materials items come in, custom becomes cheaper over 3 years.

Error handling, the underestimated line item

The ERP may reject an order because the customer is on hold, the item is inactive or a price is missing. Without safeguards, the rep thinks the order went through and the customer waits. The connector therefore needs a replay queue, a rep alert inside Salesforce and a dashboard for sales administration. Budget 2 to 4 development days for this module: it is what wins team adoption.

Mini case study

Daniel, VP Sales of an electrical equipment SME in Toronto, manages 35 reps generating 1,400 orders a month. Two order-desk staff re-key each order into the ERP, about 12 minutes per order including checks: 280 hours a month, or 2 FTEs at a loaded USD 50,000 a year each.

• Connector cost: USD 20,000, plus USD 275 a month maintenance.
• First-year cost: USD 23,300.
• Data-entry time freed: 2 FTEs, i.e. USD 100,000 a year redeployed to account follow-up.
• Keying errors avoided: about 3 % of orders, 42 fewer disputes a month.

Payback: roughly 3 months. Both staff were moved to chasing unsigned quotes.

FAQ

How long does the connector take to go live?

Allow 8 to 12 weeks for a full connector, including 2 weeks of data scoping. A first version limited to customers and orders can run in 5 weeks.

Does a mid-market ERP like Sage 100 have a usable API?

It exposes business objects and an API or SQL gateways depending on the version. Auditing your version and licences takes 1 to 2 days and drives about 20 % of the budget.

What happens when Salesforce or the ERP is upgraded?

A maintenance contract of USD 165 to 440 a month covers upgrades. Salesforce ships 3 releases a year: regression tests are included.

Do we need to clean data before the project?

Yes. In 70 % of projects we find duplicate customers or obsolete items. Plan 3 to 5 days of deduplication before the first sync.

Can we start with an iPaaS and move to custom later?

You can, but the USD 3,300 to 8,800 iPaaS setup will be lost. If your discounts are complex, go straight to a dedicated connector.
