> Build a standard chart of accounts for clients across the practice, so categorization rules, reports and reviews work the same way on every set of books.
A standard chart of accounts for clients is one list of account names and numbers that every client's books start from, with a small set of industry add-ons. It lets categorization rules, review checks and monthly reports work the same way on each set of books, so anyone in the practice can open any client and know where things are.

## Why give clients a standard chart of accounts?

A shared chart turns each client from a puzzle into a variation on one pattern. Rules written for one client can be copied to the next, reviewers check the same accounts on every file, and reports compare cleanly across clients. The cost is a one-time conversion for clients who already have their own chart.

Without a standard, each client's books carry the habits of whoever set them up. One client has "Software", another has "Subscriptions", a third has "Computer and Internet" plus "Dues and Subscriptions", all holding the same kind of charge. A bookkeeper switching between those files has to remember three answers to one question. A reviewer cannot write one checklist that works on all of them.

### Who gains from the standard

- **Preparers** categorize faster because the target account has the same name everywhere.
- **Reviewers** can scan the same accounts for the same problems on every client.
- **The practice owner** can compare margins, expense ratios and workload across clients.
- **The client's CPA** receives books in a shape they recognize from month to month, which helps the year-end handoff described in the guide to [bookkeeper and CPA collaboration](/blog/bookkeeper-and-cpa-collaboration).

The gain grows with the client list. At five clients a bookkeeper can hold every chart in their head. At thirty, the guide on [how to scale a bookkeeping practice](/blog/how-to-scale-a-bookkeeping-practice) treats standard outputs as one of the first things to fix.

## Core accounts in a practice-wide client chart

The core is the set of accounts every client receives, whatever their business: cash and card accounts, common receivables and payables, owner equity, a short list of income accounts and the overhead expenses nearly every small business pays. Keep it short. A core of forty to sixty accounts covers most service businesses.

The table is an example core for a US practice. The numbers, names and ranges are illustrative; set your own once and keep them.

| Number | Account | Typical bank line it catches |
| --- | --- | --- |
| 1010 | Operating checking | Not a categorization target; the account the statement belongs to |
| 1020 | Savings | Transfers from operating checking |
| 1200 | Accounts receivable | Customer payments against invoices |
| 2010 | Credit card, main | Card payment from checking |
| 2300 | Loans payable | Principal part of a loan payment |
| 3010 | Owner contributions | Owner deposits money into the business |
| 3020 | Owner draws | Transfers to the owner's personal account |
| 4010 | Service income | Customer deposits not tied to an invoice |
| 4900 | Interest income | Monthly interest credit on savings |
| 6010 | Bank and card fees | Monthly service charges, merchant fees |
| 6020 | Software and subscriptions | Recurring SaaS charges |
| 6030 | Rent | Monthly rent payment |
| 6040 | Utilities and phone | Power, internet, mobile carrier |
| 6050 | Insurance | Premium payments |
| 6060 | Professional fees | Legal, tax and bookkeeping fees |
| 6070 | Advertising | Ad platforms, printing |
| 6080 | Meals | Restaurant charges for business purposes |
| 6090 | Travel | Airfare, lodging, rideshare |
| 6900 | Interest expense | Interest part of a loan payment |
| 9999 | Uncategorized, to review | Lines waiting for an answer |

### Why the uncategorized account belongs in the core

A named holding account for unknown lines gives the review a single place to look. Every client's month should end with it at zero or with each remaining line explained. When the same account exists on every client, a reviewer can check it first on each file without hunting for whatever the previous bookkeeper called it.

## Industry add-ons to the standard client chart

Industry add-ons are short blocks of accounts that some clients need on top of the core: cost of goods for a retailer, job materials for a contractor, tips payable for a restaurant. Each add-on has its own number range inside the standard, so adding one never renumbers the core.

Build an add-on only when you have at least two clients who need it. A one-client account is a client-specific account and belongs under the rules for exceptions further down. Examples of add-on blocks:

- **Product sales:** inventory, cost of goods sold, freight in, sales tax payable.
- **Construction:** job materials, subcontractors, retainage receivable, equipment.
- **Food service:** food cost, beverage cost, tips payable, delivery platform fees.
- **Rental property:** rent received per property, repairs, property management fees, mortgage interest.
- **Professional services:** client reimbursable expenses, retainers held.

Reserve a range for each add-on, such as 5100 to 5199 for construction job costs. Within a range, keep the same number for the same account on every client that uses it.

### Sub-accounts versus new accounts

Some clients want more detail than the standard gives, such as advertising split by platform. Add that detail as sub-accounts under the standard account rather than as new top-level accounts. The standard report still rolls up to "Advertising", and the client sees the split they asked for.

## Numbering and naming rules for a shared chart of accounts

The rules that keep a shared chart consistent are short: each account type has a fixed number range, names say what the account holds in plain words, and nobody adds an account without updating the standard list. Write these rules on one page and keep that page with the master chart.

### Rules worth writing down

1. **Ranges by type.** Assets, liabilities, equity, income, cost of sales and expenses each get a block of numbers. Leave gaps of ten between core accounts so new ones fit.
2. **One name, one meaning.** "Software and subscriptions" holds software and subscriptions, not office supplies that happen to be bought online.
3. **No people's names in account names.** "Owner draws" works for every client. "Draws, Maria" does not.
4. **No year in account names.** Accounts last longer than a year.
5. **One owner of the master list.** One person approves additions, so the standard does not drift.

### Keep the master chart where the team can see it

Store the master chart, with its version and change history, in the same place as the practice's other working documents. The guide to [bookkeeping workpapers](/blog/bookkeeping-workpapers) covers where those documents usually live and how to reference them from each client's file.

### The standard and categorization rules

A chart and categorization rules are built together. When "Software and subscriptions" is the same account on every client, a vendor rule for a common software charge points at the same account name on every client. In AutoBankConvert, rules you write once plus each client's past coding assign transactions to accounts, and each client keeps its own rules, so the one client who books that vendor elsewhere can have a different rule.

## How do you move an existing client onto the standard chart?

Moving a client onto the standard is a mapping exercise: list the client's current accounts, decide which standard account each one becomes, then rename, merge or retire accounts in the client's books. Do it at a period boundary, ideally the start of a fiscal year, so comparisons inside one year stay clean.

### A step list for one client

1. Export the client's current chart with balances and transaction counts.
2. Map each account to a standard account, or mark it as a client-specific exception.
3. Show the mapping to the client's CPA before changing anything; they may rely on an account you plan to merge.
4. Rename accounts that map one to one. Renaming keeps the history in place.
5. Merge accounts that map many to one, following the accounting system's own instructions for merging.
6. Add the standard accounts the client is missing.
7. Mark retired accounts inactive rather than deleting them where the system allows it.
8. Update the client's categorization rules to point at the new account names.
9. Run the first month on the new chart and review it with extra care.

### Timing the move

Converting a whole client list at once is tempting and rarely wise. Pick a quiet month, move two or three clients, and fix the mapping problems they reveal before moving the rest. Avoid the months before tax filing, when the practice is busiest and the CPA is least able to answer questions. The guide to [busy season staffing for bookkeeping firms](/blog/busy-season-staffing-for-bookkeeping-firms) helps you see which months are free for project work like this.

### Expect one difficult mapping per client

Most clients have one account that does not fit anywhere: "Miscellaneous" with three years of mixed charges, or a "Loan" account that holds two different loans. Do not force these. Split the balance with journal entries at the conversion date if the detail matters, and agree the treatment with the CPA.

## When a client should keep its own chart of accounts

Some clients should keep their own chart, or most of it. The standard is a default. If changing the chart would break something the client relies on, such as a lender's reporting format, a franchise's required accounts or a parent company's consolidation, leave the chart in place and adapt your rules and reviews to it.

Good reasons to keep a client's own chart:

- **Required formats.** A franchisor, lender or grant program dictates the account structure.
- **Consolidation.** The client is one entity in a group whose charts must match each other more than they must match yours.
- **A short engagement.** A client staying six months is not worth a conversion.
- **A CPA who objects.** If the client's CPA has a reason to keep the existing structure, hear it out before you push.

Weak reasons include "the client is used to it" and "we have always done it this way". Clients rarely look at account numbers. They look at reports, and reports from a standard chart are usually clearer.

### Exceptions still need recording

When a client keeps its own chart, write down how its accounts map to the standard. That map lets the reviewer use the normal checklist and lets the owner compare that client with the rest. An unrecorded exception becomes the client nobody else can pick up.

A standard chart pays off fastest when categorization runs from it. To see rules and client history assign each line to a standard account, [get started with AutoBankConvert](/get-started).
