Running More Than One Business? Stop Managing Them in Separate Logins

A lot of small business owners don't actually run one business. They run a main one, plus a side venture that started as an experiment and quietly became real — a consulting practice and a rental property, a retail shop and an online store, an agency and a personal brand. Each one needs its own books. Almost nobody's bookkeeping tool was built with that in mind.

The default workaround is separate accounts — a different login, a different subscription, a different place to check every time you need to know how something's actually doing. It works, technically. It's also its own quiet tax on your time.

Why Separate Accounts Are More Expensive Than They Look

• You pay full price, twice. Two subscriptions for two businesses, even though you're the one person running both.
• Context-switching has a real cost. Logging out of one account to log into another isn't just annoying — it's the kind of friction that means you check things less often than you should.
• Nothing talks to anything else. If you want a combined picture of how you're actually doing across everything you run, you're exporting from two places and stitching it together yourself.

What "One Login, Multiple Businesses" Actually Means

The better model isn't merging your businesses' books together — that would be its own mess, mixing transactions that need to stay separate for tax and reporting purposes. It's keeping the books genuinely separate, but letting you switch between them without switching accounts. One login, one subscription, and a business switcher that takes you from one full set of books to another in a click.

Team Access Scales With You, Not Against You

If you eventually bring someone on to help with one of your businesses — a part-time bookkeeper, a co-founder, family — team access should work the same way per business as it would if that business were the only one you had. Nine total seats across three businesses means real room to actually delegate, not a single shared login everyone fights over.

Who This Is Actually For

Not everyone needs this — if you run one business, a single-business plan is genuinely the right fit, not an upsell to resist. This is for the specific situation of already running more than one thing and currently paying (in money, or in switching-account friction) for the privilege of keeping them separate.

The Bottom Line

Running multiple businesses shouldn't mean multiplying your subscriptions or your login screens. illico Book's Business plan lets you manage up to three businesses — each with its own fully separate books — from one account, with nine total team seats to delegate across them and priority support when you need it.
