About Singulary ‑ Merge Customers

When one shopper becomes three accounts, your order history splits and your LTV, segmentation, and email counts break. Singulary detects duplicate customers with weighted matching on name, email, phone, and address, scoring every pair by confidence. Bulk merge duplicate accounts in one click, or review customers side-by-side before you merge — orders, addresses, and tags kept intact. New signups are checked instantly, so customer data stays clean and automation handles the customer cleanup. Scan your customer database for duplicates across name, address, email, phone. Compare customer profiles side-by-side and choose which data to keep. Merge in one click, individually or in bulk — all data preserved. Set up weekly scans and duplicate detection when new customers are created. Clean up your duplicate customer records for better insights and segments. Show more Show less

If you have a large customer base which over the years has become duplicated with customers changing emails, misspelling emails or capitalizing names Singulary fixes these in the blink of an eye and then continues to monitor your base to see everything remains synced. An excellent app which has saved me massive time and is worth every cent that is worth. Can't recommend highly enough

Very simple to use and effective app. We stugguled with duplicate profiles from a very long time and this helped us in merging all the profiles with just one click.

Hidden Gem. Love this.

— Saree Ghor Charlotte

We've just begun working with this app, and all suggestions have been implemented or clarified immediately! I love how responsive and helpful the team has been and look forward to seeing how much more this app can possibly improve. It's saving me a ton of time and resources!

— Lone Star Adhesive

Best app for de-duping your store customers. Managed to remove over 1k duplicated contacts in just 1 day, a process which would have taken days if not weeks using spreadsheet and Shopify's inbuilt merge tool. Requested additional functionality to de-dupe multiple contacts at same domain and development team had added functionality in less than an hour. Clean interface, powerful and incredible cus...

This app is getter better and better each day! The developer really cares about constantly improving and making a superior product to any other tool like this on the app store. I can't be happier with how responsive they have been and how the tool has evolved and changed to meet our needs. I'll be looking specifically for them when choosing future apps as well - they seem to be on a path to major...

We are friends of the developer and helped beta test the app. That said, it's genuinely useful! We had duplicate customers we didn't know about, and the app found and helped us merge several of them quickly. The matching is solid and the merge process is simple. Definitely worth trying if you have messy customer data.

A very helpful app! We had duplicate records piling up and didn't even realised how much it was affecting our reporting. This app found matches we would have never caught manually, and the merge process was seamless. Feels great to have cleaner database now without having spent hours on it.
