It handles rack bookings on a floorplan, sends email reminders for upcoming bookings and comes with its own POS. Zellr pricing starts at €200 / month ($230 / month).

Circle-Hand is a consignment and resale platform with integrated rack booking. Sellers book a rack or shelf online, upload their items and track live sales through a seller portal.

It charges no transaction fees and connects directly to Shopify POS, Square and PayPal POS (Zettle) so you can keep your existing card reader.

1. Zellr vs. Circle-Hand: price and feature comparison

*Zellr includes an integrated POS system but lacks payment provider integrations. Staff must scan items at checkout and manually enter the total into the card reader, which creates risks for meeting tax compliance requirements in many countries (e.g. TSE in Germany).

Pros and what Circle-Hand does well for rent-a-rack stores:

Circle-Hand is a modern platform that can be used from any device. On Capterra Circle-Hand is praised by store owners and sellers for its intuitive, easy-to-learn interface and deep integrations with Shopify, Square and PayPal POS. AI-assisted item entry allows sellers to rapidly upload inventory, while advanced consignor tracking automates customized workflows like automated sales updates, booking reminders and donated inventory management. The software is continuously improved with updates released every 2 weeks and is used across more than 23 countries. Pricing starts at $99 / mo or $83 / mo in the yearly plan.

• Modern and easy-to-learn interface for store owners and sellers.

• Quick item listing process powered by AI

• Custom tracking for sales updates, booking notifications, and item donations.

• Connects directly with Shopify, Square, and PayPal POS as official partner.

Cons and where Circle-Hand falls short:

While Circle-Hand offers a well-rounded suite, its native POS is basic, meaning full retail functionality depends on third-party integrations. Its rack booking feature is relatively new, so it offers fewer deep customization options compared to legacy systems like Zellr. Access to rack booking requires the Professional plan ($179/month or $149/month billed annually).

• Rack booking is a newer feature so it offers fewer configurations.

• Cloud-based system needs stable internet connection.

• Rack booking is locked behind the Professional plan ($179/mo or $149/mo yearly).

3. Zellr - Pros and cons for rent-a-rack stores

🏆 Score: 3 / 5 stars
⭐ Reviews: 1.8 / 5 stars (8 ratings) on AppStore
💰 Price: €200 or $230 / month

(Admin Item Dashboard from Zellr - 2026)

Pros and what Zellr does well for rent-a-rack stores:

Zellr is an established legacy software with over 10 years on the market, used in 11 countries. Its biggest strength lies in its deep rack booking system, offering a level of customization and feature depth that few other solutions can match. Store owners benefit from transparent flat-rate pricing at €200 ($230) per month without tier jumps. It also provides dedicated mobile apps on both iOS and Android to help sellers keep track of their rack activity.

• Many customizations for rack reservations and scheduling.

• Over 10 years of market presence across 11 countries.

• Straightforward flat rate of €200 ($230) per month.

Cons where Zellr falls short:

Zellr’s main drawback is its dated, complex interface, which is difficult for both stores and sellers to master, an issue reflected in its 1.8/5 star rating on the Appstore. The seller portal feels unintuitive and forcing customers to complete full user registration before booking a rack creates friction that harms checkout conversion. The integrated POS lacks robust tax compliance capabilities and because it functions as a standalone desktop platform for stores, there are no integrations with external tools. Zellr requires a PC running Windows 10 or 11 for stores. Furthermore, Google Playstore indicators suggest the software is no longer actively maintained ("Unfortunately the platform that this app was originally built on is no longer updated and we've been unable to make the app compatible with the latest versions of Android"), raising concerns about future updates or potential shutdown.

• Steep learning curve and low 1.8/5 AppStore rating.

• Clunky seller interface and limited user usability.

• Standalone desktop tool with weak tax compliance features.

• App store listings indicate lack of ongoing maintenance.

4. Switching from Zellr to Circle-Hand

Switching your store from Zellr to Circle-Hand is straightforward:

1. Go to Zellr Dashboard > Clients.

2. Select all clients, right-click, and copy the data.

3. Paste the list into Excel or Google Sheets.

4. Go to Circle-Hand Settings > Data Import and upload your client file.

Because Zellr does not offer an inventory export, most stores run both systems side by side for 1 month: Ask sellers to enter all new items directly into Circle-Hand. Then process final item payouts in Zellr. Shift all subsequent payouts to Circle-Hand going forward.
