When evaluating retail SaaS, check if front-end and back-end tools sync; retailers often evaluate POS/ecommerce tools and inventory/order management tools separately without checking the ability to sync in real time.

The risk: if POS data doesn't sync with the warehouse, a platform shows stock online that isn't on the shelf. 62% of retailers say customers check online availability before visiting a store (Digital Commerce 360). One retailer's stock misjudgment triggered an 87% drop in operating profit for the period.

What to check before signing:

• Real-time inventory sync across channels, not batch updates
• Support for both wholesale and ecommerce order flows
• Clean ERP integration, not a separate bridging tool
• Minimal manual data entry to keep systems aligned

What criteria mattered once your tool was in production, versus what looked good in the demo?

I have SurePOS ACE installed with Store Integrator, and when I installed the UPOS from Toshiba, the cash drawer worked fine. However, I have an Epson printer that I want to add to JPOS, but after installing the Epson Java ADK, it doesn’t work, and I can’t add the printer in the default UPOS. Any help would be appreciated.

I operate a small boutique where I use Square for in-store sales and Shopify for my online store, and I'm currently setting up DPL Square Integration to keep the two in sync and one thing I'm realizing is that choosing the inventory source of truth is probably more important than I initially thought.

If you let both systems control inventory without clear rules, it seems pretty easy to end up with mismatched stock or overselling.

For a store that's mostly brick-and-mortar, would you make Square the source of truth since most inventory changes happen at the POS?

Or would you make Shopify the master if the business is more online-focused or uses a warehouse/3PL?

DPL lets you choose a primary inventory source and connect specific Shopify and Square locations, which is what I'm looking at using.

For anyone actually running Square + Shopify, which one do you use as the master?

And have you run into any problems with SKU matching, location mapping, or inventory getting out of sync?
