Grocery retail merchandising system support, reporting, and modernization
I support and extend grocery merchandising platforms, including Grocers Support Systems (GSS), a platform I actively develop for, and similar retail management software. That covers support, enhancement, reporting, integration, and modernization planning.
What I Help With
- Support and enhancement for grocery merchandising platforms
- Custom reporting and report changes
- Workflow improvements
- Integration with POS, warehouse, finance, and related systems, including POS item file audit and synchronization
- Troubleshooting and maintenance
- Migration and modernization planning
- Knowledge transfer where platform expertise is limited
Grocers Support Systems (GSS)
I have specific experience with Grocers Support Systems (GSS), a grocery retail merchandising platform built on IBM i. GSS environments are often tightly connected to grocery retail operations, merchandising workflows, reporting needs, and long-established business processes. That makes practical knowledge of the platform and its surrounding environment especially important. For a detailed reference on the GSS platform and its modules, see the GSS platform reference.
Other Grocery and Retail Platforms
While I have specific experience with GSS, the same approach applies to other systems common in grocery retail environments. This includes merchandising platforms like Retalix HQ and BRData; computer-generated ordering and shelf replenishment systems like Upshop / Itasca MAGIC CGO; fresh department management tools like Invatron PLUM and Periscope; warehouse logistics systems like Power Enterprise; and space management software like NIQ Spaceman.
I also work with EDI processes for invoicing and ordering, and data interfacing with wholesale distributors including UNFI.
If your environment depends on systems that have been customized and extended over years, I can likely help with support, reporting, integration, and modernization planning.
POS Item File Audit and Synchronization
In multi-store retail environments, each store's POS item file tends to drift from the host merchandising system over time. Items get added in one place but not the other, price changes propagate unevenly, and discontinued items linger as orphans. The result is pricing errors at the register, items that will not scan, and exposure to price accuracy enforcement in jurisdictions that require it.
I build automated POS audit reports that compare each store's item file against the host system and produce actionable exception reports.
- Automated comparison of store POS item files against the host merchandising system
- Identification of items to add, attribute differences (price, description, department, flags), and orphaned items to remove
- Exception reporting by store, by category of difference, with drill-down detail
- Optional automation to trigger the host system to push adds, updates, and deletes back to each store
- Scheduled or on-demand execution to keep stores continuously in sync
Free Grocery & Retail Tools
Grocery retail IT and operations teams can use these free browser-based tools for the everyday barcode, scale, identifier, and inventory-math tasks that come up across stores, distribution, and merchandising.
- PLU Code Lookup: search IFPS produce codes by number or commodity name with organic conversion
- Barcode Explorer: generate and decode UPC, EAN, GS1-128, QR, and other retail barcode formats
- Random-Weight UPC (Type 2) Decoder: decode price- or weight-embedded number-system-2 barcodes on meat, deli, and produce items
- GS1 Coupon Decoder (AI 8110): decode North American DataBar digital coupons into labelled save value, offer, and expiration fields
- POS Item File Audit Checker: compare a store POS item export against the host file and flag price, cost, and description mismatches by UPC
- WIC APL File Explorer: parse a state WIC Approved Product List into a readable table of eWIC-authorized items
- Meat Cutting Test Calculator: calculate yield percentages, cost allocation, and pass/fail against targets
- Shrink & Waste Calculator: compute COGS, gross profit, and shrink metrics by department
- Margin & Markup Calculator: compute retail margin, markup, and cost relationships
- Vendor Cost Change Impact Calculator: see how a case cost change hits unit cost, margin, and GP%, and the retail that restores it
- Mix & Match Multiple Pricing Calculator: price 3-for-$5 deals with the per-unit penny split the POS rings
- Markdown & Promotion Planner: compare GP$ at regular vs promo price and find the breakeven sales lift
- Price-Per-Unit Comparator: normalize product prices to a common unit for value comparison
- Case Pack Calculator: calculate order quantities, days of supply, reorder points, and shelf facings
- GMROI & Inventory Turns Calculator: calculate GMROI, inventory turns, days of supply, and sell-through from sales and inventory
- Retail Fiscal Calendar (4-5-4): look up NRF 4-5-4 weeks for fiscal year reporting
- Nutrition Facts Label Generator: build an FDA Nutrition Facts panel for prepared and private-label foods, with %Daily Value and rounding handled
Approach
In many cases, the right answer is not immediate replacement. It may be better reporting, better integration, better visibility, or a phased modernization plan that reduces risk while preserving continuity.
POS audit and synchronization is a practical example of how system integration, ETL, and exception reporting come together to solve a problem every multi-store retail operation recognizes.
