Brief
Strengthening the Operational Foundations of a Growing Independent Boutique
Boutique M+S is an independent retail store specializing in women's and men's ready-to-wear, located in Salaberry-de-Valleyfield. The company relies on a consistent multi-brand selection and a personalized advisory approach, built over the years around a loyal and recurring customer base.
The mandate involved migrating the company to Shopify POS, replacing a system largely based on Excel and the team's informal knowledge. The objective was not to transform the business model, but to centralize inventory, ensure reliable operations, and reduce dependence on key personnel, while preserving the identity and relational experience that are the boutique's strengths.
Goals
From informal management to reliable infrastructure
The main goal was the complete implementation of a Shopify POS, including real-time inventory, structured reservation management, and automated accounting integration with QuickBooks. Ultimately, the team needed to be able to receive an item and make it available for sale the same day, track sales and discounts without manual adjustments, and generate reliable reports by brand and season.
Beyond the tool, the objective was to transform operational knowledge held by a few individuals into a documented and transferable process, capable of supporting growth without increasing the mental burden on management.

Complexity and challenge
Migrating without interrupting an operation built on relationships
Boutique M+S operated exclusively as a physical store, with Excel as the organizational pivot for purchases, inventory, and accounting adjustments. Supplier purchase orders contained rich information (sizes, variations, cost prices, delivery schedules), but this information was never automatically integrated once the goods were received. Each receipt required manual checks, and the actual inventory was only visible through the team's memory.
This reality created a real business risk. An item could be sold as available when it had already been set aside, or vice versa. The difficulty of the mandate lay in structuring a multi-brand product architecture (brand, model, color, size, season) precise enough to allow for reliable analytical reading, without complicating the daily work of a team that had never operated with a centralized inventory system. The timeline added another constraint. The switchover could not take place during intensive purchasing periods, for fear of creating an operational overload during peak season.
Approach
Structure before switching over
The approach was sequenced into four phases to align with the store's business cycles. The first phase focused on architectural decisions: defining the structure of products and variants (brand, model, color, size, season), establishing SKU and barcode rules, and configuring Shopify before integrating any existing inventory.
This step was crucial. An imprecise structure would have compromised the reliability of future reports and complicated each merchandise receipt. The principle adopted was simple: prioritize the supplier barcode when reliable, and only generate an internal code at the time of product creation, never upon receipt.
Once the foundations were laid, the team used Shopify POS for new products while maintaining the old system in parallel, to integrate existing inventory category by category. This dual use allowed for testing real in-store flows, quickly correcting errors, and training the team in real situations rather than theoretically.
The official switchover was planned after the reception of summer collections, a period considered more conducive to a controlled transition than during peak shopping intensity. A QuickBooks integration was configured in parallel to automate the synchronization of sales and payments once the POS was stable.
Solution
Centralized Inventory, from Supplier to POS
The solution is based on a Shopify POS structured around a clear product architecture: supplier as brand, color as main variant, size as secondary variant, season as tag. Purchase orders are now created directly in Shopify at the time of purchase, with variants, cost prices, and estimated receipt dates, allowing an item to be activated for sale on the same day it is physically received.
The team was trained in two parts: product creation, purchase orders, and inventory taking on one hand; and receiving, sales, returns, and POS management on the other. QuickBooks integration now automatically synchronizes sales and payments, reducing the manual adjustments that previously burdened accounting tracking.
Results
A store that gains mastery without losing its identity
Since the migration, Boutique M+S has a centralized inventory and a receiving process that makes an item available for sale the same day, rather than after several days of manual processing. QuickBooks integration eliminates some of the accounting adjustments that previously relied on Excel as a bridge between systems.
The store's identity, that of a local business built on advice and customer loyalty, remains intact. The transformation was not intended to replace it, but to give it a stronger foundation to evolve.
“What I appreciated most about Maze was their willingness to understand my business before suggesting anything. Katherine is organized, a good listener, and synthesizes information clearly; I felt like we were speaking the same language. I quickly realized we were a true team.”
