SixBit Review 2026: What the Five Editions Actually Cost

SixBit prints five prices on one page: $29.99, $49.99, $99.99, $139.99 and $184.99 a month. Most review sites quote only the first. That matters if you are budgeting, because the gap between the cheapest edition and the $99.99 one is not support speed or polish. It is how many eBay selling accounts and users you get, whether inventory tracking exists at all, and whether the software relists and adjusts quantities for you. This SixBit review for 2026 goes through each edition, the Windows hardware it needs, what users say on the review sites, and the part of an eBay dropshipping store it leaves to you.

Quick answer: our SixBit review in brief

Quick answer: SixBit is Windows desktop software for listing, inventory and order management, built for eBay sellers and also working with Etsy, Shopify and Hip eCommerce. It comes in five editions from $29.99 to $184.99 a month, billed monthly with no contract, no setup fee and no percentage of your sales. It rates 4.4 out of 5 from 16 reviews on both Capterra and Software Advice, where users praise the support and the batch tools and complain about the learning curve. It suits a seller with owned stock and a Windows machine. It does not find products or order from suppliers, so it suits an Amazon or AliExpress dropshipper far less.

Our pick for supplier-sourced eBay stores: Ecomli. It finds products, lists them from Amazon or AliExpress, keeps price and stock in line with the supplier, and on Pro and Scale places the supplier order within your buying limits, from $29 a month. Ecomli publishes this review and makes that product, so weigh our view accordingly. Every SixBit fact below comes from SixBit's own pages or the named review sites, checked in September 2026.

SixBit at a glance

What SixBit is, and what to check first

SixBit Software is a Windows application for sellers who list, track and ship a lot of items. The company, based in Sayre, Pennsylvania, says on its About page that it has served eBay sellers since 1998 and describes itself as the developer of the first listing tool for eBay. The workflow will feel familiar to anyone who ran desktop eBay tools before everything moved into the browser. You keep a local catalog of items, push listings up in batches, pull orders down, print labels and run reports against your own database.

That history explains the shape of the product. SixBit's feature menu covers listing management, inventory management, order management, consignments, reporting, integration and customization. It is strong on the parts of selling that are really data entry at scale: batch item editing, custom fields, description wrappers, CSV and XML import and export, and customizable packing lists and labels. It is not a marketing tool, and it is not a sourcing tool.

If you arrived from our roundup of SixBit alternatives for eBay sellers, the useful question is not whether SixBit is good software. It is whether the edition you can afford includes the two or three features you came for. The features do not simply improve as you climb. Several appear only at a specific tier. Inventory tracking and profit and loss reports are missing from the entry edition entirely, and automatic relisting and automatic quantity adjustment start at Enterprise. Our guide to the best eBay listing software shows the same pattern across the category: the headline price buys the editor, and the operations features sit one or two tiers up.

SixBit pricing in 2026, edition by edition

These figures come from SixBit's own pricing page, checked in September 2026. Prices are per month, with no contract and no setup fee.

Read that table as a staircase of limits rather than a feature list. At $29.99 you get the editor and two seats. At $49.99 you get the warehouse side of the business: stock levels, purchase history, carrier postage printing and reports you can hand to an accountant. At $99.99 the software starts doing things on its own, such as relisting what ended, adjusting quantities and running allocation plans. Duo and Max are for sellers who want a second marketplace, or several, alongside eBay.

Two commercial terms deserve more attention than they usually get. SixBit takes no percentage of sales: its FAQ says your subscription lets you list as many items as you like without extra fees if you sell more. A seller doing $40,000 a month pays the same as a seller doing $4,000, which matters against tools priced on order volume. And changing edition is done from inside the account, with the FAQ noting that a change simply hides or shows functionality, with no reinstall.

One point to confirm before you buy Duo or Max. SixBit's comparison table calls the limit "Number of Sites", while its plan cards describe Duo as selling on two channels. Every edition works with eBay US, UK, Canada and Australia. If you sell on more than one eBay country and nothing else, ask SixBit how it counts those sites before you pay for a higher edition.

The Windows requirement most SixBit reviews skip

The review sites rarely lead with the most consequential fact about the product: SixBit is installed Windows software with published hardware requirements, and there are two sets of them. The pricing page gives the minimum. A separate recommended hardware page asks for more.

The hardware page adds three details worth knowing. SQL Server 2022 is the recommended database version for new installations. SixBit is not natively compatible with macOS. And while virtualization software can put it on a Mac, SQL Server cannot be installed on Apple M1, M2 or M3 chips or other ARM-based processors, so a recent Mac is not a workaround.

None of that is a flaw. It is the deal you are making. A local database is why batch operations on a large catalog stay fast and why your reports run against your own data. It also means no phone access, no logging in from a borrowed laptop, and an upgrade path that eventually means buying a computer rather than changing a plan. Sellers who want their tools to follow them between machines usually look at browser-based options instead, and our guide to the AutoDS Chrome extension walks through one of those workflows.

The hardware also decides who you can hire. On a desktop system, a virtual assistant needs access to your machine, or a machine of their own on your network, plus a seat in your edition. On Home & Hobby a seat means one of two. Before you count $29.99 as your total cost, add the Windows machine, the power to keep it running while listings sync, and the second seat you will want the first time someone helps you.

What SixBit leaves to you on a supplier-sourced store

SixBit's job starts once you already know what you are selling and where it comes from. It manages listings, inventory, orders, consignments and reports. Nothing on its feature list researches products, matches a supplier to an item, watches a supplier's price and stock, or places the supplier order when a sale lands. For a seller working from owned stock in a garage or warehouse, none of that is missing. For a seller sourcing from Amazon or AliExpress, it is most of the daily work.

This is where Ecomli fits. Ecomli is a non-API browser extension for eBay dropshippers that works through the eBay seller account already signed in to your desktop Chrome browser, so there is no API connection to authorize. The two products barely overlap. SixBit answers "how do I manage the thousands of items I already have?" Ecomli answers "what should I list next, and how do I keep it accurate without checking every item by hand?"

• Finding products. Ecomli's Product Hunting searches Amazon by keyword, Best Sellers or store pages, collects the products from an AliExpress store link, and can research a competitor eBay seller's sold history and match those items to an Amazon or AliExpress supplier. A match is a lead to check, not proof of profit. SixBit has no equivalent, because finding products was never its job.
• Listing with the supplier attached. Create Listings reads the supplier product, prices it with your markup, writes optional AI titles and descriptions, applies your description template and fills in eBay's listing form in your own seller session, up to 10 listings at once.
• Price and stock drift. A supplier raises a price and your listing keeps the old one, so you sell at a loss. Or a supplier runs out and you sell something you cannot ship. Stock Monitoring checks your Amazon and AliExpress suppliers and updates the eBay listing using your rules: it adjusts the price with your markup and price-change tolerance, or sets the quantity to 0 or ends the listing when stock is gone. Our piece on eBay repricer margin defense works through where to set the floor, and the repricing software comparison shows how other tools handle it.
• Ordering from the supplier. SixBit prints postage for orders you have already bought, and the buying is manual. Ecomli's Starter plan uses manual ordering too. On Pro, you click Auto Order and Ecomli places the supplier order in your own browser. On Scale, once you turn it on, Advanced Auto Ordering runs on Ecomli's servers and places the supplier order for new eBay orders without a click, as long as each order is within your buying limits (a maximum purchase price and a maximum loss).
• Tracking. Tracking Conversions converts supported AliExpress and Amazon TBA tracking into eBay-compatible tracking and adds it to the eBay order after its automatic checks.

Be clear on the mechanics before you compare costs. Ecomli's browser tasks run through your signed-in browser, so the browser needs to be open while they work, and only Scale's Advanced Auto Ordering runs on Ecomli's servers. Safety Shield screens products, AI copy and the eBay draft for flagged brands and restricted items before publishing, as a checkpoint rather than a guarantee. The Ecomli pricing page sets out what Starter, Pro and Scale each include, and the how it works section on our homepage shows the workflow end to end.

SixBit vs Ecomli

How to do this in Ecomli

If you run a supplier-sourced catalog in SixBit today and want Ecomli to take over the supplier side, the move goes through your eBay listings. Ecomli does not import SixBit files.

1. Download the eBay Active Listings CSV from Seller Hub. Your listings stay live on eBay throughout.
2. Open Migration in Ecomli, choose the eBay Active Listings source and upload the file.
3. Check the supplier mapping. Each row needs the eBay item number. Ecomli reads the supplier from the Custom label (SKU), whether that holds an ASIN, an AMZ_<ASIN> label or an AliExpress product ID, or from a supplier-URL column. Rows it can't read are held for review so you can add the Amazon or AliExpress link. Nothing is guessed.
4. Set Stock Monitoring rules: markup, the out-of-stock rule, restock quantity and price-change tolerance.
5. On Pro or Scale, set buying limits before you switch on Auto Ordering.

Listings without an Amazon or AliExpress supplier stay on eBay but are not monitored, so an owned-stock side of the business can stay in SixBit or Seller Hub.

Who SixBit fits in 2026, and who outgrows it

SixBit fits a specific and real seller: someone with a large catalog of owned stock, a Windows machine that stays on, and a preference for keeping their own data. Consignment sellers are well served, since consignments have their own section in the product rather than a workaround. The review sites back up that picture.

On Software Advice, the praise centers on support and speed: one reviewer calls the support "the best I've ever experienced", and another says it "dramatically speeds up the process of creating listings." The complaints are consistent too. Reviewers mention a learning curve with "the controls and understanding the window layout", an interface that "looks like 'old' software", and updates that bring new bugs. The Capterra listing tells the same story. Keep the sample size in mind. Sixteen reviews, the newest from late 2024, is a thin and dated base for any buying decision.

SixBit fits less well in three situations. If you sell from suppliers rather than stock, the daily work happens outside SixBit and you end up paying for two systems. If you want to work from more than one machine or from a phone, the architecture is against you. And if your catalog is small, $49.99 a month for inventory tracking is a lot to pay before you have much inventory to track.

There is also the growth question. eBay reviews your selling limits every month based on your sales and buyer feedback, and its help page notes that active and sold listings, including Good 'Til Cancelled ones, count toward your monthly limit. Listings that never sell take up room without building your record. SixBit relists them at Enterprise. Ecomli's Auto Pruner (Basic on Pro, Advanced on Scale) ends them instead, in one click by your rules, such as zero views or zero sales over 15 to 60 days, using fresh Seller Hub reports. Advanced Auto Pruner can then relist removed products with fresh supplier data and a new AI title and description, as new eBay items. Both approaches are defensible, and the right one depends on where your stock sits: in your garage, or in a supplier's warehouse.

If SixBit looks like more machine than you want to run, our 3Dsellers review and CrazyLister review cover browser-based listing tools, our AutoDS alternatives guide covers automation suites, and our Terapeak alternatives roundup covers research. Our Sellbery review looks at a lighter multichannel option. Whatever you pick, run the numbers against eBay's own selling fees first. Software is rarely the largest line in the margin.

Frequently asked questions

Is SixBit worth it in 2026?

For an owned-stock seller with a Windows machine and a catalog big enough to need batch editing and inventory tracking, yes. The monthly price stays flat as sales grow because there are no sales fees, and users rate its support highly. For an Amazon or AliExpress dropshipper, it covers listing and orders but none of the supplier work, so you would still need a second tool.

How many eBay accounts and users does each SixBit edition allow?

Home & Hobby allows two selling accounts and two simultaneous users. Small Business raises both to five. Enterprise, Enterprise Duo and Enterprise Max are unlimited on both counts. Employee account administration follows the same ladder, so a two-person business on the entry edition has no spare seat for a virtual assistant. Check this before price, because it decides whether an edition works for your team at all.

Is there a contract, setup fee, or cut of your sales?

No to all three. SixBit is a monthly subscription you can leave at any time, with no setup fee and no percentage of what you sell. You can move between editions from your account, and a change shows or hides features rather than requiring a reinstall.

What hardware do you need to run SixBit properly?

The minimum on the pricing page is Windows 8, 10 or Windows Server 2012 or newer, a 100GB drive, 8GB of memory and a 4-core, 8-thread processor with a PassMark score of 7,000 or better. SixBit's recommended specification for a single PC raises that to 16GB of memory and a 500GB solid state drive. A multi-user network host is recommended at 8 cores and 16 threads, 32GB of memory and a 1TB solid state drive. Budget for that machine alongside the subscription.

Does SixBit work on a Mac?

Not natively. SixBit says virtualization software can run it on a Mac, but SQL Server, which SixBit needs, cannot be installed on Apple M1, M2 or M3 chips or other ARM-based processors. So if you work on a Mac, you would need an Intel-based model running Windows through virtualization.

Can you try SixBit before paying, and what is included?

Yes. New customers can use the edition they pick free for 30 days, and SixBit includes its Gold Support Plan for that first month. The support matters more than usual here, because installing a desktop database, connecting selling accounts and importing a catalog take longer than most web onboarding. Import your real catalog during that month rather than a sample, since batch speed on your own data is what you are testing.

Which marketplaces does SixBit cover, and which need a higher edition?

eBay US, UK, Canada and Australia work on every edition, as does Etsy, and eBay Motors support is limited to parts and accessories. Hip eCommerce needs Small Business or above, and Shopify needs Enterprise or above. The number of sites you can run at once is one on the first three editions, two on Enterprise Duo and unlimited on Enterprise Max.

What is a good SixBit alternative for eBay dropshippers?

Ecomli is our pick if you source from Amazon or AliExpress. It covers the supplier work SixBit leaves out: Product Hunting, listings built from the supplier product, Stock Monitoring, Auto Ordering on Pro and Scale within your buying limits, and Tracking Conversions. Plans are $29, $99 and $199 a month, billed monthly with a 7-day money-back guarantee on your first payment. For owned stock, our CrazyLister alternatives list covers other listing tools.

The bottom line

SixBit is capable, long-running Windows software for sellers who own their stock. The five editions from $29.99 to $184.99 a month are really a ladder of seats, inventory features and automation, so pick the edition by the features you need, then check your hardware against the recommended specification, not just the minimum. If your supplier ships the orders, Ecomli is our pick: it handles the product research, supplier price and stock checks, ordering and tracking that SixBit leaves to you, from $29 a month.
