The Brief
This merch print project is a three-application Laravel suite for bulk customised merchandise sales. It connects supplier product feeds, stock quantities, delivery dates, pricing, marking costs, catalogue browsing and quote preparation into one private backend workflow.
Challenge
The business sells customised print merchandise sourced from multiple distributors. Each supplier exposes product data, stock, delivery timing, prices and decoration costs differently, so sales staff need a single operational view without manually reconciling spreadsheets before every quote.
Backend Suite
The system is split into an inventory app for master product and stock data, a catalogue app for product browsing and enquiry carts, and a quote engine for quote preparation and offer document handling. The apps share product truth while keeping catalogue content, admin controls and quote records in the right place.
Supplier Integrations
The inventory app includes a shared API handler plus supplier-specific import handlers for distributors including Anda, Asgard, Axpol, Cookie, Easygifts, FalkRoss, Jaguar, Macma, Malfini, Maxim, Midocean, PAR and USBSystem. Scheduled synchronisation updates products, stock, delivery ETAs, markings and supplier-specific costs.
Catalogue Workflow
The catalogue app imports selected products from the inventory app, assigns local categories, supports SKU and name search, availability filters, color filters, supplier-code filters, extra attribute filters, related categories, product detail pages, variant behaviour and an enquiry cart with category-specific quantity/comment labels.
Quoting Edge Cases
The quote engine stores full offer snapshots so prices, product names, markings and calculations remain auditable after the supplier data changes. Deleted inventory products are marked on old offers, blocked from editing and excluded from print output rather than silently breaking historic quote records.
Outcome
The backend gives the sales workflow a consistent path from supplier sync to product discovery to quote preparation, with live stock visibility, future delivery data and print-cost context available where staff need it.

Challenge
Sales staff needed one operational view of customised merchandise data because suppliers expose product details, stock, delivery timing, prices and decoration costs in different formats.
Solution
The backend suite separates inventory, catalogue and quote workflows while sharing product truth, supplier synchronisation, local catalogue controls, enquiry carts and quote snapshots for auditable offer handling.
Outcome
The sales workflow now has a consistent path from supplier sync to product discovery to quote preparation, with live stock visibility, future delivery data and print-cost context available where staff need it.
Lessons
- Supplier feeds need normalised stock, price, delivery and marking data before they become useful to sales staff.
- Catalogue browsing and quote preparation should share product truth while keeping local categories, enquiry behaviour and quote records separate.
- Quote snapshots protect historic offers when supplier products, names, costs or availability change later.
