n-How to Add Another Company to QuickBooks Online
From inside a company you're already signed into, click the gear icon and select Add another company, then pick a subscription tier and sign in with your existing user ID when QuickBooks asks. This creates a brand-new, separate company with its own billing and its own blank books under the same login; nothing from your current company carries over automatically.
The full walkthrough
1. Sign in to a company you already manage. Adding another company starts from inside an existing one, not from a logged-out signup page.
2. Click the gear icon, then Add another company. This routes you to QuickBooks' plan-selection screen specifically for a new company, separate from your current one.
3. Choose a subscription tier for the new company. It's independent of whatever plan your existing company is on. A Simple Start company and an Advanced company can sit under the same login without any conflict.
4. Sign in with your existing user ID when asked. This is the step that actually attaches the new company to the account you already use, instead of accidentally spinning up a second, disconnected login.
5. Set up the new company's basics. Legal name, industry, and entity type, same as a first-time setup, since QuickBooks treats this as a genuinely new company even though it's your second, third, or further one.
6. Use the company switcher to move between them going forward. Once both exist, clicking your company name in the top left shows every company tied to your login, and you pick which one to work in.
What actually gets harder once you're running more than one
Adding the company itself takes a few minutes. Running two or more well is the part nobody warns you about. Each company bills separately, has its own chart of accounts, its own vendor and customer lists, and its own bank connections; none of that is shared or synced between companies automatically, even though they're tied to the same login.
That shows up fastest for a business that opened a second company for a second location, a new entity, or a franchise, and expects some of the setup, categorization rules, vendor list, connected apps, to transfer over. It doesn't. Everything gets rebuilt from scratch in the new company unless someone deliberately sets it up to match.
The other recurring pain is reporting across companies. QuickBooks Online doesn't have a native combined report spanning multiple companies; getting a consolidated view across two or three company files means exporting each one separately and combining them by hand, which is exactly the kind of recurring manual task that gets missed or done inconsistently once the novelty wears off.
What we've built on top of QuickBooks multi-company setups
Shared setup across companies
Chart of accounts structure, vendor lists, and categorization rules get kept in sync across multiple QuickBooks companies, instead of someone rebuilding the same setup by hand in every new one.
Consolidated reporting across companies
Numbers from several QuickBooks companies get pulled and combined into one report automatically on a schedule, instead of someone exporting each company separately and stitching the totals together by hand every month.
What's the actual pain point once you're running multiple QuickBooks companies?
Tell us whether it's the setup, the reporting, or keeping the lists consistent, and we'll tell you what can run itself across all of them.
Running more than one QuickBooks company and feeling the seams?
Tell us what's inconsistent or manual across your companies right now, setup, reporting, vendor lists, and we'll tell you whether it can be kept in sync automatically instead of redone by hand in each one. Multi-company setups are one example of this kind of gap; we close the same kind of gap anywhere else it shows up in the business.
