The verdict in three sentences
A Toronto building materials merchant with 4 depots and 3,500 SKUs typically loses 3 to 5 % of inventory value a year to damage, delivery errors and untracked transfers. An ERP like Odoo requires 60,000 to 140,000 CAD of implementation, a custom system 110,000 to 220,000 CAD (2026 ballpark), over a 3 to 5 month project. The right choice depends on your trade credit, your inter-depot transfers and your contractor pricing, not on the vendor's logo.
Where the 3 to 5 % shrinkage comes from
In the trade of cement, rebar, lumber, drywall and roofing, shrinkage rarely comes from one dramatic theft. It piles up: broken bags written off without a record, extra rebar dropped at a loyal contractor's site, transfers between the Etobicoke and Scarborough yards logged on paper and forgotten, a rushed annual count in December.
| Shrinkage source | Estimated share | Software control |
|---|---|---|
| Damage and moisture (cement, drywall) | 25 to 30 % | Damage report with photo on tablet |
| Job site delivery variances | 20 to 25 % | Proof of delivery signed on mobile |
| Unreconciled inter-depot transfers | 15 to 20 % | In-transit status until receipt |
| Cash sales without invoice | 10 to 15 % | Stock release blocked without ticket |
| Unit of measure errors (piece, bundle, tonne) | 10 % | Configured unit conversions |
| Internal theft | 10 to 15 % | Surprise cycle counts |
The key tool is cycle counting on tablets: each day, the yard lead counts 30 to 50 randomly selected SKUs, weighted toward the most valuable and most stolen. In three months the whole inventory is recounted without closing the yard, and variances show up by employee and product family.
Odoo implementation or custom software
Odoo handles purchasing, multi-warehouse stock and accounting well with a competent partner. Custom gains the edge when commercial rules are specific: contractor pricing by volume and by job, credit limits by account and by sales rep, delivery on company trucks or customer pickup, and integration with existing dispatch tools.
| Criterion | Odoo with integrator | Custom software |
|---|---|---|
| Implementation cost (2026 estimate) | 60,000 to 140,000 CAD | 110,000 to 220,000 CAD |
| Recurring licences | 30 to 50 CAD per user per month | No licence, maintenance quoted |
| Timeline | 3 to 4 months | 3 to 5 months |
| Offline yard operation | Limited | Designed in from day one |
| Contractor credit limits | Configurable, rigid | Your exact house rules |
| Accounting | Built-in module | Export to QuickBooks or Sage |
| Lock-in | Odoo partner | Code and database you own |
A practical rule: if more than 30 % of revenue goes out on account to contractors, invest first in the credit module, whatever the platform. That is where the largest losses hide, ahead of shrinkage.
Modules for version one
Multi-depot stock with bin, lot and unit of measure. Inter-depot transfers with in-transit status. Counter sales and invoicing with card, cash, e-transfer and account payment. Trade credit with limit, terms and automatic hold above threshold. Tablet cycle counts. A daily margin dashboard by depot, based on weighted average cost.
Infrastructure matters as much as software: reliable connectivity at each yard, an LTE backup, and a sync layer that catches up sales recorded offline. Budget two weeks of training for yard staff, which is almost always underestimated.

Marc, owner of a building materials merchant in Toronto, carries on average 6,000,000 CAD of inventory across 4 depots. Estimated annual shrinkage is 3 %, or 180,000 CAD. Receivables over 90 days reach 400,000 CAD, of which about 10 % is written off each year, or 40,000 CAD.
With cycle counting, he targets halving shrinkage: 90,000 CAD saved per year. Tighter credit limits cut bad debt by a third: another 13,300 CAD. Total gain: about 103,000 CAD per year. A 160,000 CAD custom build pays back in roughly 19 months, an Odoo implementation at 100,000 CAD plus licences in 12 to 14 months, if it truly fits his credit rules.
FAQ
How much does multi-depot stock software cost in Toronto in 2026?
Expect 60,000 to 140,000 CAD for an Odoo implementation and 110,000 to 220,000 CAD for custom software, as a ballpark. Budget depends mostly on the number of depots and on credit rules.
Does it work when the connection drops?
An offline-first tool records sales and movements locally and syncs as soon as the network returns. With LTE backup, yards stay operational more than 99 % of the time.
How long does the project take?
Plan 3 to 5 months, including 3 to 4 weeks for the initial count and loading of 3,500 SKUs. Cycle counts can begin in month two.
Can it handle contractor accounts and card payments?
Yes, account sales with limits and terms sit alongside card and e-transfer payments reconciled automatically against invoices. This typically trims cash variances by 1 to 2 % of counter revenue.
What shrinkage reduction is realistic?
Merchants running daily cycle counts usually cut shrinkage by 40 to 50 % within a year. On 6 M CAD of inventory at 3 %, that is 72,000 to 90,000 CAD.
