# Mortar Reviews **Vendor:** Accumula **Category:** [Omnichannel Commerce Software](https://www.g2.com/categories/omnichannel-commerce) **Average Rating:** 4.8/5.0 **Total Reviews:** 10 ## About Mortar Mortar is the most complete POS-Shopify integration for brick-and-mortar retailers. It connects Lightspeed R-Series, Lightspeed X-Series (Vend), and Heartland Retail to Shopify, keeping inventory, orders, products, and customer records in sync in real time across your physical stores and your online store. Mortar is built by Accumula, a company that has been building retail integrations since 2013. WHO IT'S FOR Mortar is a good fit for retailers who: - Run one or more physical store locations alongside a Shopify storefront - Use Lightspeed R-Series, Lightspeed X-Series (formerly Vend), or Heartland Retail as their POS - Have struggled with inventory getting out of sync between their POS and Shopify - Want to offer buy online, pick up in store (BOPIS) to their customers - Are scaling — adding new store locations, expanding their online catalog, or both It's not the right fit for retailers who only sell online, or for POS systems outside the three listed above. WHAT MORTAR SYNCS - Inventory: Every sale, return, and inventory adjustment in your POS updates Shopify in real time, and vice versa. Supports multiple store locations. - Orders: Online orders placed on Shopify are sent to your POS. In-store sales update Shopify inventory automatically. - Products: Add or update products in your POS and they sync to Shopify. Manage your catalog in one place. - Customers: Customer records stay consistent between your POS and Shopify, including purchase history. - Refunds, exchanges, and order edits: When a customer returns something at your register, Shopify updates. When an order is edited after the fact, it flows through. Most integrations don't support this. HOW MORTAR COMPARES vs. the native Lightspeed-Shopify integration: The native integration syncs inventory and basic product data, but it doesn't support refunds processed in Lightspeed updating Shopify, exchanges, or order edits. It also requires manual product matching in many cases. Mortar handles all of these natively and uses automatic product linking — no manual SKU mapping required. vs. SKU IQ: SKU IQ is a competing integration that also connects Lightspeed and Shopify. The key difference is product linking: SKU IQ requires you to manually map products between systems. With Mortar, that process is automatic. Mortar also handles refunds, exchanges, and order edits; SKU IQ does not. HOW IT WORKS Setup typically takes less than an hour. You connect your POS and Shopify accounts, Mortar automatically links your products between the two systems, and sync begins. The initial product link runs automatically — you don't need to manually match SKUs. Most merchants are live within a few hours. CUSTOMER RESULTS - A DTC clothing brand scaled from 4 to 54 store locations while keeping their POS and Shopify in sync throughout. - An outdoor sports retailer onboarded a catalog of over 100,000 SKUs in 3 days using Mortar's automated product linking. - Multiple merchants report eliminating the manual inventory reconciliation work and customer service problems that previously wasted several hours per week. FREQUENTLY ASKED QUESTIONS Does Mortar support multiple store locations? Yes. Mortar supports multi-location inventory out of the box. You can manage inventory across all your physical locations and your Shopify store from within your POS. What happens when a customer makes a return in-store? When a return is processed in your POS, Mortar updates Shopify — the order status, inventory, and any associated records all stay accurate. This is one of the most common gaps in competing integrations. Do I need to manually match my products between my POS and Shopify? No. Mortar links products automatically based on SKU and product data. You don't need to manually map products between systems. Does Mortar support buy online, pick up in store (BOPIS)? Yes. Mortar supports BOPIS workflows with Lightspeed and Shopify. Is there a free trial? Yes. Mortar offers a 14-day free trial. See usemortar.com/pricing for plan details. Which POS systems does Mortar support? Lightspeed R-Series, Lightspeed X-Series (formerly Vend), and Heartland Retail. ## Mortar Reviews ### 1.

Accumula Review **Rating:** 4.5/5.0 stars **Reviewed by:** Britney M. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 19, 2024 **What do you like best about Mortar?** The product performs precisely as described in its advertisements. The meticulous attention to detail and comprehensive documentation is truly remarkable. Additionally, the superior customer support greatly enhances the overall experience. The onboarding process for integrating and implementing the product was exceptionally smooth. Before settling on Accumula, we had tried out several competitors.

Perfect product and support **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Sporting Goods | Small-Business (50 or fewer emp.) **Reviewed Date:** October 12, 2023 **What do you like best about Mortar?** The product works exactly as advertised, the level of detail and documentation is incredible, the customer support is superior, and the onboarding for our integration and implementing it was a breeze. We have utilised some competitors before landing on Accumula, only regret was that we didn't make the switch sooner. **What do you dislike about Mortar?** We have been up and running with Accumula for around a month now and genuinely zero complaints at all. **What problems is Mortar solving and how is that benefiting you?** Reestablished a connection between our POS system and Shopify, it's fast, accurate and very straightforward. ### 4. Incredibly helpful staff. I've always received quick knowledgable help to all questions asked. **Rating:** 5.0/5.0 stars **Reviewed by:** Chad A. | Operational Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** December 01, 2022 **What do you like best about Mortar?** Software is great but the staff is the key to their success. Any issues have always been resolved promptly and fully. **What do you dislike about Mortar?** I dislike the requirement to use 40 characters here because my answers is nothing. **What problems is Mortar solving and how is that benefiting you?** Connecting our in-store POS with our Shopify website.

Savannah/Onboarding has differentiated this product from most other SAAS offerings!! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail | Small-Business (50 or fewer emp.) **Reviewed Date:** June 09, 2022 **What do you like best about Mortar?** - Onboarding; Savannah has been amazing in helping us get up & running. We have scheduled 2 45 minute meetings with her already to get fully configured initially and she has been extremely helpful and patient - this really has been a gamechanger as most other companies are great pre sale but then leave you alone, Accumula has really differentiated here and I believe this will be reflected in retention of customers!! - User friendly platform = Easy to navigate - Integration with Shopify/Lightspeed seems to be great for auto updating prices to shopify from Lightspeed (& auto product creation) **What do you dislike about Mortar?** Only potential negative so far for us is specific in that we would like the feature to assign the same SKU in shopify to multiple variations but this isnt yet possible! I believe it is coming in the future **What problems is Mortar solving and how is that benefiting you?** The business problem Accumula solves for us is two fold; 1. Discrepancies between pricing records in Lightspeed and our Shopify (website). The fact that we have to manually update prices twice in both platforms mean we often face mismatches which we have to honour and thus even lose margins on products whilst frustrating customers 2. Extreme amounts of time wasted on manual data entry and reconciliation of prices between both platforms. This wastes so much time as we have thousands of products ### 6. Amazing from start to finish **Rating:** 5.0/5.0 stars **Reviewed by:** Chris C. | Director, Mid-Market (51-1000 emp.) **Reviewed Date:** March 15, 2022 **What do you like best about Mortar?** We are a chain of 11 stores whom went from Lightspeed webstore to shopify with accumula being the connector. The whole process from onboarding to set up was faultless, Evan and the team were first class and Evan was extremely generous with his time, especially with the time difference from Seattle to Australia. His honesty and their deliverance of what they promised was spot on - highly reccomend. **What do you dislike about Mortar?** Nothing. These guys were awesome all round. **Recommendations to others considering Mortar:** Enjoy! **What problems is Mortar solving and how is that benefiting you?** Oversolds - they have a "flash sale" function which was amazing and helped our stores not have oversold product anymore - a big deal as it caused so many headaches with the older ecomm system - these guys nailed it. ### 7.

Accumula saves me time so I can keep being productive **Rating:** 4.5/5.0 stars **Reviewed by:** Museum S. | Museum Store Assistant Manager **Reviewed Date:** March 22, 2021 **What do you like best about Mortar?** I appreciate that Accumula saves me time and peace of mind, by updating inventory quantities in our brick and mortar store, and online. I no longer need to manually enter online sales into our POS - Accumula does it for us. It's easy to use. The onboarding team is responsive, helpful and eager to help you even with small problems. I'm so glad we're using this software! **What do you dislike about Mortar?** I wish there was a way to code Shopify Tips/Donations into Lightspeed. At the moment, it just shows as "No Product Found" in Lightspeed, which is the same message when a product on Shopify is not found in your Lightspeed store. Other than that, no complaints at this time! **What problems is Mortar solving and how is that benefiting you?** The main problem we're solving is keeping inventory quantities up to date. Using Accumula ensures that we won't oversell a product online, and also shows our online sales in our brick and mortar daily sales reports. It saves me a great many hours of manually inputting sales and updating inventory quantities. ### 10. Great service, outstanding support **Rating:** 5.0/5.0 stars **Reviewed by:** Jim K. | Shopify Expert + Shopify Partner, Small-Business (50 or fewer emp.) **Reviewed Date:** June 25, 2021 **What do you like best about Mortar?** I loved the service itself, but the support and onboarding with Savannah were excellent. Everything about the experience was great. **What do you dislike about Mortar?** I think the documentation in Accumula can be a little better. **What problems is Mortar solving and how is that benefiting you?** We were trying to migrate and then sync inventories between Lightspeed Retail and Shopify.
