Cost Estimates and Selection Checklists
ERP cost by business size: illustrative budgets for 5, 25 and 75 users
Illustrative five-year ERP budgets for a small service firm, a growing distributor and a mid-sized manufacturer in Canada, and which system category usually fits each.
ERP costs scale with users, complexity and the amount of implementation help you need, so the useful question is not "what does an ERP cost?" but "what does a business like mine typically need, and what would that cost over five years?" Below are three illustrative profiles, a small service business, a growing distributor and a mid-sized manufacturer, each with the system category that usually fits, the main cost lines and a five-year budget range. Use them to sense-check your own estimate in the TCO estimator, not as prices.
This guide is part of the ERP selection checklist. All ranges are placeholders to show the arithmetic, not survey data or vendor prices.
Profile 1: 5-user professional services firm
Situation: a consulting or engineering firm in Alberta with 12 staff, 5 of whom use the financial system; project billing and time entry are the main needs; no inventory.
Usual fit: an accounting suite with project and time-tracking add-ons, or an entry-level cloud system with project accounting.
| Line (illustrative) | Low | High |
|---|---|---|
| Subscription, 5 users × 5 years at $300–$900 per user per year | $7,500 | $22,500 |
| Time-entry users (7 staff, light licences or add-on) over 5 years | $2,100 | $8,400 |
| Set-up, migration and training | $3,000 | $12,000 |
| Internal time | $2,000 | $5,000 |
| Five-year total | $14,600 | $47,900 |
At this size, a full ERP is often more than you need. The key question is whether the accounting suite handles project costing well enough; if not, a project-focused system may be the better step.
Profile 2: 25-user wholesale distributor
Situation: a distributor in Ontario and Quebec with 40 staff, 25 system users (15 full, 10 light), one warehouse, about 2,000 items, sales to businesses in both provinces, an e-commerce channel and USD purchases from suppliers.
Usual fit: an entry-level or mid-market cloud ERP with inventory, purchasing, multi-currency and an e-commerce connector, implemented by a partner.
| Line (illustrative) | Low | High |
|---|---|---|
| Subscription, 25 users × 5 years at a blended $900–$1,800 per user per year | $112,500 | $225,000 |
| Add-ons and connectors (e-commerce, shipping) over 5 years | $10,000 | $30,000 |
| Implementation, migration, integrations, training | $40,000 | $110,000 |
| Internal time and back-fill | $15,000 | $40,000 |
| Contingency | $8,000 | $25,000 |
| Five-year total | $185,500 | $430,000 |
Specific points for this profile: GST and QST tax codes for customers in both provinces, French-language customer documents for Quebec, and a decision on whether payroll stays with a dedicated payroll provider. See payroll integration and accessibility and French-language requirements.
Profile 3: 75-user manufacturer
Situation: a manufacturer in British Columbia with 160 staff, 75 system users including shop-floor terminals, two plants, bills of materials, work orders, lot traceability, quality control, two legal entities and US customers invoiced in USD.
Usual fit: a mid-market or industry-specific manufacturing ERP, sometimes with separate shop-floor or warehouse systems integrated.
| Line (illustrative) | Low | High |
|---|---|---|
| Subscription, 75 users × 5 years at a blended $2,000–$4,200 per user per year | $750,000 | $1,575,000 |
| Add-ons (quality, advanced planning, EDI) over 5 years | $40,000 | $150,000 |
| Implementation, migration, integrations, training | $200,000 | $600,000 |
| Internal time and back-fill | $60,000 | $150,000 |
| Contingency | $40,000 | $120,000 |
| Non-recoverable BC PST on software, if applicable | Check | Check |
| Five-year total (before PST) | $1,090,000 | $2,595,000 |
At this size, light-user and device licences make a large difference: if 40 of the 75 are shop-floor users on cheaper licences, the subscription line can fall considerably. Model it with the pricing models guide. British Columbia applies PST to software in many cases; include it if it applies, because it is a cost you cannot recover. See GST/HST and QST on ERP SaaS.
Why the ranges are wide
The high end is often two to three times the low end. The spread reflects real uncertainty: the edition you need, negotiated discounts, how much customisation you insist on, data quality and how much work your staff can take on. Narrow it by doing the requirements and scripted demos in the selection checklist, then replacing every line with a quote.
Signs you are buying the wrong size
- Too small: you need spreadsheets alongside the system for inventory, costing or consolidation; month-end requires manual journal entries from other systems.
- Too big: most modules are unused after a year; users complain that simple tasks take many screens; implementation took longer than the business could afford.
Moving up later is common and often sensible. The cost to consider is a second migration, so choose a first system that can export your data cleanly. See contract terms on exit and data export.
FAQ
Is there a minimum size for ERP?
No formal minimum. Many small businesses run well on an accounting suite with add-ons; ERP becomes worth it when inventory, production, multiple entities or integration needs outgrow that setup.
Why is the per-user price higher for larger systems?
Mid-market and manufacturing systems include more functions and usually need more implementation and support. Larger deals also tend to have more negotiation room, so list prices rarely tell the whole story.
Can a small business afford a mid-market ERP?
Sometimes, with a narrow first phase. Check the five-year total, not just the first year.
Are these ranges based on market data?
No. They are placeholders chosen to show how a budget is assembled. Use your own quotes.
