QuickBooks Online vs CustomBooks: Pricing, Inventory, and Which One Fits (2026)

QuickBooks Online and CustomBooks, the cloud accounting product formerly sold as AccountingSuite, aim at fairly different buyers, so the choice usually comes down to whether you run a product or inventory business and how much you value a large accountant network. QuickBooks Online tends to win on the number of U.S. accountants who already use it, its mobile apps, and its app marketplace. CustomBooks tends to win on built-in inventory, unlimited users on every plan, and a lower price for a business that would otherwise need the top QuickBooks tiers to manage stock.

The quick version:

• CustomBooks includes unlimited users on every plan, plus unlimited accountant seats. QuickBooks Online limits users by tier, from one on Simple Start up to 25 on Advanced.
• CustomBooks builds inventory management into its Professional plan, while QuickBooks keeps inventory to its Plus and Advanced tiers.
• QuickBooks Online has a far larger network of U.S. accountants and bookkeepers who already work in it, a bigger app marketplace, and full mobile apps.
• Neither switching to CustomBooks nor cancelling QuickBooks preserves your full QuickBooks history with its attachments and audit trail, so archive that history before you cancel.

QuickBooks Online vs CustomBooks at a glance

Prices are U.S. list prices in 2026 and change often, so confirm the current figure on each company's pricing page before you decide.

Pricing compared

QuickBooks Online has five plans at current U.S. prices in 2026: Solopreneur at $20, Simple Start at $38, Essentials at $75, Plus at $115, and Advanced at $275 per month. Payroll and payment processing are billed on top of those figures, so the real monthly cost is usually higher than the plan price, and Intuit has raised prices most years.

CustomBooks publishes four plans plus a custom Enterprise tier at current U.S. prices in 2026: Startup at $19, Business at $109, Professional at $299, and Professional with eCommerce at $399 per month, with annual billing discounted. Every plan includes unlimited users and unlimited accountant seats, which is the difference owners notice most on a growing team, and each comes with a 30-day free trial that needs no credit card. The catch sits at the bottom: the $19 Startup plan is basic accounting, banking, and project tracking only, without invoicing, sales, purchases, inventory, or payroll, so a business that bills customers usually starts at the $109 Business plan to compare fairly against QuickBooks Essentials or Plus.

Line the plans up by what each business actually uses and the picture depends on your needs. A service business comes out close: CustomBooks Business at $109 sits between QuickBooks Essentials at $75 and Plus at $115, and it includes unlimited seats where QuickBooks Essentials caps you at three. A product business is where CustomBooks can save more, because its inventory lives on the $299 Professional plan while QuickBooks holds full inventory features for Plus and, more so, Advanced at $275, and QuickBooks still caps how many users each plan includes.

Users, and why unlimited seats matter

The clearest split on cost is user access. CustomBooks includes unlimited users on every plan, along with unlimited seats for your accountant or bookkeeper, so everyone who touches the books can have a login at no added cost. QuickBooks Online counts users per plan: one on Simple Start, three on Essentials, five on Plus, and up to 25 on Advanced, with your accountant seats granted separately.

If only you and your accountant use the books, the QuickBooks limits rarely bite. If several people need access, the flat CustomBooks pricing can be meaningfully cheaper.

Does CustomBooks handle inventory better than QuickBooks?

For many product businesses, yes, and it is the main reason to look at CustomBooks. Its Professional plan builds in inventory management with warehouse transfers, lot and serial number tracking, assembly builds, and FIFO or weighted-average costing, closer to a light ERP than a bolt-on. Reviewers describe CustomBooks as strong on integrated inventory across multiple sales channels, with a Professional with eCommerce tier that connects to Shopify, Amazon, eBay, and other stores through ShipStation.

QuickBooks Online includes inventory too, but only on its Plus and Advanced plans, and its tracking is lighter than what CustomBooks offers at the top. The tradeoff is price and reach: QuickBooks reaches basic inventory at Plus for $115, below the $299 CustomBooks Professional plan, and far more accountants and third-party warehouse apps already plug into QuickBooks. So a simple stock count leans QuickBooks on cost, while a distribution or multi-channel seller that needs real inventory depth leans CustomBooks.

Features and fit: where each one pulls ahead

Both platforms cover the core well: invoicing, bank feeds, reconciliation, expense tracking, and financial reports. CustomBooks connects to more than 15,000 banks and credit card providers for its daily feeds, and it offers its own Cloud Payroll as a paid add-on or a Gusto integration, much as QuickBooks sells QuickBooks Payroll on top of its plans. The differences show up around those basics.

QuickBooks Online tends to lead on the surrounding ecosystem. It has full iOS and Android apps, a large U.S. app marketplace, and the widest pool of accountants and bookkeepers who already work in it every day. If you expect to hand the books to a professional, finding one fluent in QuickBooks is simple in the United States. CustomBooks is a smaller and less familiar product, so an outside accountant may need to learn it first.

CustomBooks tends to lead on inventory, customization, and seat pricing, and it aims squarely at product businesses that have outgrown basic bookkeeping but do not want a full ERP. Its weak spots are the flip side of being a smaller vendor: reviewers note a dated, crowded interface, no dedicated mobile app, and slowdowns at very high transaction volumes. If polish and a phone app matter to you, QuickBooks is the stronger choice.

Who should choose which

Choose QuickBooks Online if you want the widest pool of U.S. accountants who already know the software, you rely on its mobile apps or its large app marketplace, or your inventory needs are light enough for the Plus plan.

Choose CustomBooks if you run a product, distribution, or multi-channel business that needs real inventory depth, you want several people in the books without paying per seat, or you value customization at a set monthly price. For a business that is genuinely on the fence, built-in inventory and unlimited users are what usually tip owners toward CustomBooks, while accountant availability and mobile apps tip them back toward QuickBooks.

Either way, one thing does not change: the decision to switch accounting software is separate from the decision about what to do with the history sitting in QuickBooks today.

Switching from QuickBooks to CustomBooks? Export your history first

A migration and a complete record are not the same thing. Moving into CustomBooks means importing the data it needs to get you running: your chart of accounts, customers and vendors, item list, opening balances, and a limited stretch of recent transactions to set those balances. That is enough to start keeping books in the new system. It is not a full copy of everything QuickBooks held.

Three things routinely stay behind in QuickBooks after a switch, and they are the records you are most likely to be asked for later:

• Your attachments, meaning the receipts and documents attached to transactions, along with the link showing which transaction each file belongs to. QuickBooks' own export separates the files from their transactions, and an import into new software does not carry them across.
• The audit log, the record of who entered or changed each transaction and when. It does not move to CustomBooks.
• Your full multi-year history in its original QuickBooks form, everything beyond the balances and recent transactions the import sets up.

That gap only becomes a real loss because of what happens next. When you cancel a paid QuickBooks Online subscription, Intuit keeps the company in read-only mode for 12 months and then deletes it permanently. After that deletion the company is gone, and resubscribing opens a new, empty company rather than restoring the old one. A free trial gets only 90 days. The read-only year explainer covers exactly how much time you have.

The safest time to build the archive is while QuickBooks is still live, before you migrate and before you cancel. Get a complete, verified copy of the QuickBooks company first. If you would rather not spend days rebuilding receipts and reports by hand, that is the service we run. We build one complete, audit-ready archive of your QuickBooks Online company: the full general ledger in both cash and accrual basis, every financial report for each year, every attachment still linked to its transaction, and the audit log, delivered as a single download so you can move to CustomBooks and cancel with your whole history preserved.

If you are closing the business rather than switching, the same archive can help support a future IRS request for records, long after the subscription is gone.

Frequently asked questions

Is CustomBooks cheaper than QuickBooks Online?

It depends on what you run. CustomBooks includes unlimited users on every plan, so a team that would otherwise need a higher QuickBooks tier for more users often saves. On a plan-to-plan basis the two are close in the middle, with CustomBooks Business at $109 near QuickBooks Essentials at $75 and Plus at $115, and CustomBooks tends to win most clearly for a product business that would otherwise need a top QuickBooks tier for inventory. Compare the specific plans you would actually use.

Can I move my data from QuickBooks Online to CustomBooks?

Yes, though an import typically brings across your chart of accounts, contacts, items, balances, and a limited window of transactions to get you running, and it does not carry your attachments or audit log. Plan to keep a separate, complete copy of your QuickBooks history rather than assuming the move preserved everything.

Will I lose my QuickBooks history if I cancel after switching?

You can. A cancelled QuickBooks Online company goes read-only for 12 months, then Intuit deletes it permanently, and resubscribing does not bring a deleted company back. Anything the import left behind, including attachments and the audit log, is erased on that schedule unless you archived it first.

Do I still need to keep my old QuickBooks records if the business moved to CustomBooks?

Usually. The IRS generally expects business records to be kept for at least three years, with longer periods in some cases: four years for many employment tax records, six years if income was substantially understated, seven years for a worthless-securities or bad-debt claim, and no limit at all for a fraudulent or unfiled return. That is far longer than an import window covers, and your CPA can tell you which period applies to you.
