Your counter sale and your pallet order run on two systems that never talk
A custom POS (Point of Sale) system for a Mississauga business costs $40,000 to $130,000 and 3 to 6 months. You build past Square, Toast, and Clover when you sell across channels, retail counter plus B2B wholesale plus warehouse pickup, and need one inventory and one customer record across all of them. For a single-location retail or restaurant, Square or Toast is genuinely excellent. Custom is for the operation where the POS has to bridge counter, wholesale, and warehouse.
Square and Clover are built for a counter: one customer, one transaction, one inventory. A Mississauga distributor that also sells retail runs a counter sale on Square, a wholesale pallet order on a separate system, and warehouse pickups on a third, with inventory that doesn't reconcile across them. A customer who buys retail and wholesale is two different records, and the stock sold at the counter doesn't decrement what the B2B side thinks it has.
The case for owning your pos
A custom POS unifies the channels: one inventory that decrements whether the sale is at the counter, a wholesale order, or a warehouse pickup, and one customer record across all of them. It supports retail checkout and B2B pricing tiers and net terms in the same system, integrates with your accounting, and gives you a true cross-channel view of stock and customers, which the single-channel design of Square and Clover can't provide.

Exactly what you get
A POS that bridges your channels: a retail counter sale, a B2B wholesale pallet order, and a warehouse pickup all draw from one inventory and tie to one customer record. It handles retail checkout and B2B pricing tiers with net terms, processes payments compliantly, and reconciles every channel to one set of books. For a Mississauga distributor selling both retail and wholesale, that single source of truth is the whole reason to build.
How to choose a developer in Mississauga
Ask how the team unifies inventory and customer records across channels, because that's the hard part Square skips. Confirm they handle PCI-compliant payment processing and integrate your accounting so the books reconcile. If you sell B2B, make sure pricing tiers and net terms are in scope. A team that has built multi-channel retail or distribution systems will know that the value is in the shared truth across counter, wholesale, and warehouse, not in the checkout screen itself.
- One inventory across retail counter, B2B wholesale, and warehouse pickup
- A single customer record spanning every channel they buy through
- Retail checkout and B2B pricing tiers with net terms in the same system
- Accurate cross-channel stock that decrements correctly wherever a sale happens
- Accounting integration so all channels reconcile to one set of books
- More expensive than a Square terminal and a monthly fee
- Payment processing and PCI compliance become your responsibility to integrate
- Hardware choices and maintenance are now yours to manage
- For a single-channel retail or restaurant, Square or Toast is better and cheaper
- !They treat it as a single-counter POS; ask how wholesale and pickup share inventory
- !No PCI or payment plan; ask how processing is handled compliantly
- !They ignore B2B pricing; ask how net terms and tiers work
- !No accounting integration; ask how channels reconcile to one set of books
- !No cross-channel customer record; ask how a dual-channel customer is unified
Most Mississauga teams pricing pos end up comparing notes on supply chain, business intelligence dashboards, booking & scheduling too; the systems share one data spine.

Frequently asked questions
Why can't we just use Square for everything?
Square is built for a single counter channel. A Mississauga distributor selling retail and wholesale needs shared inventory and unified customer records across channels, plus B2B pricing and net terms, none of which Square handles. So stock diverges and customers fragment, which is the build signal.
How does cross-channel inventory work?
One inventory decrements whether the sale happens at the counter, as a wholesale order, or at warehouse pickup, so counts never diverge. That single source of truth is the core of a custom POS and the thing separate systems can never deliver, no matter how you sync them.
Do we have to handle PCI compliance ourselves?
You integrate a compliant payment processor, and the developer should architect the system so card data never touches your servers directly, keeping your PCI scope minimal. A team that hand-waves payment security is a red flag; insist on a clear, compliant processing design.
Can it support B2B net terms and retail checkout together?
Yes, that's a primary reason to build. The same system handles a retail card swipe and a wholesale order on net-30 with tiered pricing, instead of forcing your B2B customers through a retail checkout that doesn't fit. For a dual-channel Mississauga business, this is often the deciding feature.
When is Square or Toast genuinely the better choice?
For a single-location retail shop or restaurant with one channel and one inventory, Square or Toast gives you great hardware, support, and a low monthly cost. Custom only wins when you must bridge retail, wholesale, and warehouse into one inventory and one customer record.
