A planogram is only as accurate as the data behind it.

When choosing planogram software, the key question is how reliably product and sales data reach the tool from the ERP and POS: which connections it supports, how often it updates and who keeps the integration running.

Why does planogram software need ERP and POS data?

Planograms are built on two kinds of data. Product data from the ERP sets what goes on the shelf and how it fits: dimensions, case packs, categories and the assortment for each store. Sales data from the POS sets how much space each product deserves.

Without an integration, merchandisers export spreadsheets and enter data by hand. Planograms are then built on outdated numbers, new products are missed and delisted ones stay on the plan.

What data should flow between ERP, POS and planogram software?

Most data flows one way, from the retailer’s systems into the planogram tool:

Data	Source	Used for
Product master data: SKU, dimensions, case pack, category, brand	ERP	Building planograms to scale and calculating shelf capacity
Assortment by store: listed and delisted items	ERP	Store-specific planograms
Sales by SKU and store	POS	Sizing facings and analysing planogram performance
Stock levels	ERP or warehouse system	Spotting products at risk of running out
Store list and formats	ERP	Sending the right planogram to each store

Some retailers also send data back, such as shelf capacity from the planogram into replenishment planning.

What should retailers check before choosing planogram software?

When comparing the best planogram software for retail, check how each platform connects to your ERP and POS before looking at advanced features. Reliable data exchange affects planogram accuracy, store-specific assortments and the effort needed to keep layouts current across the chain. Six questions to ask any vendor:

1. 1. How does data get in? Check the connection methods (API, direct database connection or scheduled file imports) and the data formats (for example CSV, JSON or SQL database exports).
   2. How often does it update? Automated daily imports suit most sales analysis, but the right frequency depends on how often the retailer reviews assortments and planograms.
   3. How are codes matched? SKU codes, store IDs and units of measure must match across systems.
   4. What happens when a load fails? The tool should show failed loads and errors, not silently keep old data.
   5. Who maintains it? Some vendors run the integration for you; others give your IT team a tool to manage it.
   6. What data leaves your systems? Agree what is transferred, where it is stored and who can access it.

PlanoHero, cloud-based planogram software, offers both models: its team can manage the integration, or the retailer’s IT team can use the PlanoHero Connector to exchange data with POS, ERP and accounting systems through SQL, CSV or JSON data exports. Retailers can also connect their systems through its API.

Common integration problems and how to avoid them

• Incomplete product data. Missing dimensions or case packs make planograms inaccurate. Clean the master data before the first load.
• Different IDs in different systems. The same product has one code in the ERP and another at the till. Agree on one key and map the rest.
• One-off imports. Data is loaded once at launch and never refreshed. Set an automatic schedule from day one.
• No owner. When nobody is responsible, failed loads go unnoticed for weeks. Name an owner on both the retailer and vendor side.

FAQ

What is planogram software integration?

It is an automatic data connection between planogram software and the retailer’s ERP, POS or accounting systems. It replaces manual exports and keeps planograms based on current product and sales data.

Which systems should planogram software connect to?

Usually the ERP for product and assortment data and the POS for sales. Some retailers also connect accounting or warehouse systems for stock levels.

What data formats do planogram tools accept?

Connection methods usually include an API, direct database access or scheduled file imports. Common data formats are CSV, JSON and SQL database exports. Check the vendor’s list before signing.

How often should sales data be updated?

At least as often as planograms are reviewed. Many retailers load sales daily so that analysis reflects recent demand.

Does a retailer need an in-house IT team to integrate planogram software?

Not always. Some vendors run the integration themselves, while others provide a connector that the retailer’s IT team manages.
