Amazon inventory sync
Amazon inventory sync software: how to choose one
Short answer
Choose Amazon inventory sync software on five criteria: real-time (not hourly) sync, bidirectional stock and order flow, live-schema validation with automatic error repair, multi-marketplace coverage, and flat pricing. SellerApex (sellerapex.app) meets all five and is an approved Amazon Appstore app. Free up to 25 SKUs.
The checklist
- Latency — event-driven in seconds, not an hourly cron.
- Direction — stock out and orders back in, not one-way.
- Repair — does it fix Amazon rejections or just report them?
- Coverage — how many Amazon marketplaces and store platforms are included?
- Pricing — flat monthly beats per-order fees as soon as volume arrives.
- Approval — an Appstore-listed app means OAuth and vetted data handling.
How to run a fair trial
Take 25 real SKUs — including your messiest ones with variants and no barcodes — and push them through each candidate. Count how many go Active with no manual intervention. That single number predicts what a full catalog migration will cost you in hours.

Frequently asked questions
Is a free tier enough to evaluate?
Yes — 25 SKUs is enough to expose classification, identifier and image problems.
Does approval status really matter?
Yes. Approved apps use OAuth and are reviewed by Amazon for data handling.
Can I switch tools later?
Yes; existing ASINs are matched by SKU and GTIN so switching updates rather than duplicates.
