How a small firm runs books for many client companies without extra staff

You are not trying to produce a group consolidation pack. You are trying to finish Friday without posting the landscaper's fuel bill into the rental LLC, and without hiring a fifth person whose only job is remembering which login is which.

The work that grows with headcount is not posting. It is:

• Finding the right company file
• Knowing whether the bank feed is still connected
• Knowing which period is still open
• Knowing who at the client answers a question
• Keeping supporting documents with the entity they belong to

Fix those five and a small team can carry more entities. Hire into that mess and you just get a faster mix up.

Publication 583 is blunt. If you are in more than one business, you should keep a complete and separate set of records for each business. The same publication says you may use a different accounting method for each business only if you keep a complete and separate set of books and records for each. (Publication 583)

For a firm, that means one set of books per client legal entity. Two LLCs owned by the same person are two files. A Schedule C inside a 1040 is not a second company file. An S corp that pays the owner is its own file. Classes, locations or tags inside one QuickBooks company are labels. They are not a second set of books.

Intuit's own help for adding a company file says each company needs its own paid subscription, the data stays separate, users invited to one company do not automatically get the others, and bank accounts connected to one company are not visible in another. You connect feeds on each file. Lists you copy across will not stay in sync later. (Create or add another company file)

The IRS also expects supporting documents (invoices, deposit records, paid bills) kept in an orderly way, by year and type. (What kind of records should I keep?) Put those documents in the entity folder, not in a shared "Smith family" dump. Going paperless is the naming and retention rule. This page is which set of books they attach to.

In QuickBooks Online Accountant you open a client file from the Go to QuickBooks dropdown, and you leave it with Back to practice or by picking another client. If the company is missing, the client is not on the firm list or you do not have access. (How to switch between companies)

Write a switch rule on one page and make everyone use it:

• Never keep two company files open in two browser profiles as a way to copy and paste. That is how the wrong bill gets posted.
• Before you post, read the company name in the toolbar out loud. It sounds silly. It catches the rental LLC when you meant the operating company.
• When you leave a file, leave a one line note on the close board: feed ok, uncategorized count, next question, who owns it.
• Do not start a second entity until the note is written. The board is the memory. Your head is not.

If you work in Xero or another ledger, the same rule applies. One file on screen. A written note when you leave. Do not invent a second set of logins in a spreadsheet that only one person understands.

The AICPA's starting advice for small firm automation is to pick a well documented, routine task and to map it before you connect tools. Copying data between systems, sending the same emails, and linking one action to the next are the shape of work they name. (How to build automations in your small firm)

Standardize the shell. Leave the facts unique.

Related entities get a line on the worksheet pointing at each other. They still do not share a company file. Owner draws, management fees and rent between companies are transactions you post on both sides, not a reason to merge the books.

Illustrative, not a client story. A four person shop in the first week of the month: owner CPA, two bookkeepers, one admin. About 40 client companies. They do not open every file on Monday. They open the board.

Two rules keep this from turning into 40 quiet emergencies. First, a bookkeeper does not open a file that is in Feed stopped or Question out unless they are the one clearing that blocker. Second, review is a queue. The owner does not "just peek" at whatever is open on someone's screen.

That board is the extra staff you did not hire. It only works if every entity is a row, including the dormant rental that posts twice a year.

• Two legal entities in one company file. Classes will not save you when a banker, a buyer or an examiner asks for one set of books.
• One bank feed into two files. Intuit says accounts connected to one company are not visible in another, and you connect each file separately. (Create or add another company file) Do not try to share a feed as a shortcut.
• A shared "owner" inbox as the filing system. Personal and entity documents will mix. Route files the way the tax firm routing guide describes.
• Auto posting in a file you have not watched for a month. Rules belong in the CAS checklist, with a person still reviewing what they have not proven.
• The return itself. Separate books make tax prep cleaner. They do not prepare, sign or file anything. That stays with a CPA.

Download the entity worksheet. One row per legal entity. Columns for legal name, EIN, entity type, year end, related entities, ledger, feed status, close owner, reviewer, client contact, and whether the engagement covers bookkeeping, payroll, bill pay or none of those.

Fill it from the practice software and the ledger list, not from memory. The entities that hurt you in March are the ones that never made it onto a list.
