Grocery retail merchandising system support, reporting, and modernization
I provide practical help for organizations that depend on grocery merchandising platforms, including Grocers Support Systems (GSS) and similar retail management software. This includes support, enhancement, reporting, integration, and modernization-related 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.
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.
- Barcode Explorer — generate and decode UPC, EAN, GS1-128, QR, and other retail barcode formats
- SIL File Explorer — parse Standard Interchange Language files used by retail scales and POS systems
- Check Digit Validator — validate GTIN, UPC, and EAN check digits
- Retail Fiscal Calendar (4-5-4) — look up NRF 4-5-4 weeks for fiscal year reporting
- Margin & Markup Calculator — compute retail margin, markup, and cost relationships
- ABC Analysis Tool — classify SKUs into A/B/C tiers by velocity or value
- Safety Stock Calculator — compute safety stock and reorder points
- EDI File Parser — inspect UNFI and other wholesale distributor EDI files
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.
