Multi-entityAccounting for Multiple LLCs: Running Several Companies Without Tangled Books

Most people who own several LLCs didn't plan it that way. There was the original business. Then the building it operates from got its own LLC because the attorney suggested it. Then a second location, or a side venture, or a holding company someone recommended at a conference. Now there are four companies, and the key ring has keys nobody can identify.

That's normal. What causes trouble is when the bookkeeping never caught up with the org chart, and one company's bank account pays for everything.

This guide covers how accounting for multiple LLCs should work, the setup mistakes that tangle the books, and a simple monthly routine to keep everything separate but still easy to see as a whole.

Why each LLC needs its own books

An LLC is a separate legal entity. Part of what makes that separation hold up is behaving like separate entities: separate bank accounts, separate records, and documented transactions between them. Whether and how that protects you legally is a question for your attorney, and how each entity is taxed is for your CPA. From the bookkeeping side, the rule is simple: one entity, one set of books.

In QuickBooks Online, that usually means a separate company file for each LLC. It's tempting to use one file and split entities with classes, since classes let you tag transactions by department or location. But classes slice one company's results. They were never built to hold three companies' assets and debts apart. Our guide to classes vs locations in QuickBooks explains where they're useful instead.

A matching chart of accounts saves hours later

Multi entity bookkeeping gets much easier when every company uses the same chart of accounts, or close to it. Same account names, same numbering, same structure. A landscaping company and a real estate LLC won't use every account, and that's fine. The point is that "6100 Rent" means rent everywhere.

A matching structure makes it possible to compare entities, build combined reports, and spot when a cost landed in the wrong company. Without it, every combined report turns into a translation project.

Intercompany transactions: the part that tangles

Money moves between related companies all the time. One LLC pays another's bills, lends it cash, or charges it rent or a management fee. Each of those is an intercompany transaction, and it has to be recorded on both sides.

Here's a hypothetical owner with three LLCs:

• GreenCo, a landscaping business
• Parcel LLC, which owns the building GreenCo operates from
• Bloom LLC, a new retail plant nursery

In March:

1. GreenCo pays Parcel LLC $6,000 in rent. GreenCo records rent expense. Parcel records rental income.
2. Parcel's $9,000 property tax bill is due, and it's short on cash, so GreenCo pays it. GreenCo records a $9,000 receivable, "Due from Parcel LLC." Parcel records the property tax and a $9,000 liability, "Due to GreenCo."
3. GreenCo lends Bloom $15,000 to buy opening inventory. GreenCo records "Due from Bloom LLC." Bloom records "Due to GreenCo."

At month end, GreenCo's "Due from Parcel" should equal Parcel's "Due to GreenCo," to the penny. If they don't match, one side is missing an entry.

The mistake to avoid: GreenCo pays Parcel's tax bill and records it as GreenCo's own expense. Now GreenCo's profit is understated, Parcel's is overstated, and nobody can say what each business actually earned. Our deeper guide to intercompany accounting and consolidated financial statements covers eliminations and combined reports.

Shared costs: allocate them on purpose

Some costs genuinely serve several companies: the bookkeeper, the office manager, the accounting software, the owner's time. Common approaches:

• One entity pays and charges the others a management fee.
• Costs are split by a set formula (headcount, revenue or hours) and billed out monthly.

Either way, write the method down. Agreements between related companies, and how they're taxed, should be set up with your CPA and attorney. The bookkeeping job is to record the charges consistently every month, the same way, so they don't depend on someone remembering.

Keep the owner's money out of it

When there are several companies, the owner's personal spending tends to sneak in through whichever card is handy. A family dinner on the GreenCo card, a personal Amazon order on Bloom's. That's a separate tangle on top of intercompany. If it's already happened, our guide to untangling mixed personal and business expenses shows how to sort it out.

A monthly multi-entity routine

Multi entity accounting doesn't need to be complicated. It needs to be regular:

1. Reconcile every bank and credit card account in every entity.
2. Record intercompany transactions on both sides the same day they happen, or at least the same week.
3. Match intercompany balances between each pair of entities and fix any difference.
4. Post shared-cost allocations or management fees.
5. Close each entity's books and review its P&L and balance sheet.
6. Build a combined or consolidated view for the owner, with intercompany activity removed.

Step six is where the owner finally sees the whole picture: total cash across companies, combined profit, and which entity is carrying which.
