We’ve been using Inventory Planner for around six or seven years now across multiple Shopify stores, and it’s become a core part of how we manage stock. The replenishment suggestions save a significant amount of time and the forecasting has become more accurate over the years. Like any software it has its quirks, but the overall value it provides to our buying process is hard to argue with. The team have also been helpful whenever we’ve had queries.

We integrate Inventory Planner with our own system through the API, for purchase orders and warehouse transfers. The API is solid and the docs are clear. Support is the highlight. When we ran into an issue with webhooks, Teresa took the ticket, got the engineers involved, and came back with a real answer and a fix within days, following up until everything was confirmed on our side. Fast, direct, and competent. Thanks, Teresa.

Thank you for sharing this! It's great to hear the API and documentation have held up well for your purchase order and warehouse transfer integration with your own system. We're especially glad Teresa was able to take ownership of the webhook issue, bring in the engineers, and follow through until everything was confirmed on your side. Fast, direct, and competent is exactly the standard we want our support team to meet, and we'll be sure to pass along your thanks to Teresa.

I really can't fault IP and IP support. Super fast response, and Jordan pin-pointed my issue straight away and resolved it.

I had some difficulties about getting the accurate forecast numbers and Jordan figured out what the issue was and explained to me via video call. It was really helpful. I think I know what my team should do from now on.

I would like to sincerely thank Jordan Milne for the outstanding support he provided in resolving the issue we experienced with Inventory Planner. Jordan was highly professional, responsive, and knowledgeable throughout the entire process. He took the time to understand the issue, investigated it carefully, and followed up with us until everything was fully resolved and working correctly. What I appreciated most was his commitment, patience, and continuous follow-up. He made sure the issue was completely resolved rather than simply providing a quick response. A special thank you to Jordan Milne for his excellent support and dedication. This level of customer service gives us great confidence in Inventory Planner and makes a real difference in our overall experience. Highly recommended!

Thank you as well for the recommendation. We're glad this experience has given you confidence in Inventory Planner! -Mike G.

We run a curated DTC outdoor and lifestyle catalogue, so buying decisions are unforgiving — get it wrong and you're either sitting on dead stock or out of your best sellers. Inventory Planner has made those calls far more confident. The connectivity with our WMS is the foundation of it. Stock positions, inbound deliveries and sales data all flow through cleanly, so the buying recommendations are based on what's actually in the warehouse rather than a snapshot from last week. That single sync has saved us hours of reconciliation every month. What's kept us on it is how much you can tailor. Lead times, safety stock, seasonality, replenishment rules by brand and category — nothing is locked into someone else's idea of how our business should work. We've shaped the forecasting around our own buying cycles rather than the other way round. The customer support deserves a mention of its own. Responses are fast, come from people who clearly understand inventory planning rather than reading from a script, and they've helped us configure things properly rather than just closing tickets. That's rare. Highly recommended for any e-commerce business that's outgrown spreadsheets.

Thank you for such a detailed and thoughtful review! It's great to hear that the WMS connectivity has become the foundation of your buying confidence, with stock positions, inbound deliveries, and sales data flowing cleanly so recommendations reflect what's actually in the warehouse rather than a snapshot from last week. We're also glad the flexibility around lead times, safety stock, seasonality, and replenishment rules by brand and category has let you shape the forecasting around your own buying cycles, exactly as it should be. Thank you too for the kind words on support. Fast responses from people who genuinely understand inventory planning, and who help you get things configured properly rather than just closing tickets, is exactly the standard we aim for. Thanks as well for the recommendation to businesses outgrowing spreadsheets. We really appreciate it!
