How do you keep the business side of a practice small?

Count the tabs open on your laptop at the end of a Friday. A booking tool, a payments dashboard, a document with your terms, a spreadsheet of who owes what, an inbox with three threads trying to find a time. Each one does a job. Together they’re a second job nobody pays you for.

The four systems

1. 1

   Bookings, payment and the agreement

   One place where a client picks a time, accepts your terms and pays. When those are three tools, you’re the thing that connects them.

2. 2

   One calendar

   The one you already live in. Everything booked lands there, and nothing gets booked over what’s already in it.

3. 3

   Money put aside for tax

   A share of every payment, decided before it lands. 25% is a common start. How much should you set aside?

4. 4

   Records

   Invoices, payments, fees and the agreements clients accepted, kept where your accountant can find them. What records does your accountant need?

What you can skip

• A CRM. A list of clients with what they bought and a private memo each is enough for a practice of one.
• Project management software, unless you run several projects at once with other people in them.
• A dashboard of charts. You need to know what’s owed, what’s booked and what’s yours to spend.

Time

Where does the week go? and How much admin is normal? count the hours, and When should you hire help? is for when the count is too high.

Tools and words

What software does a practice of one need? is the short list, switching booking tools is for when yours stops fitting, and the words of a practice of one has the terms in a line each. Which business frameworks are worth it? covers the thinking tools.

Every system you don’t need is an hour a week you get back.

Everything on running the practice

• Which business frameworks are worth it when you work alone?

  Eight of them, out of the hundred on the usual lists. The other ninety-two were built for companies with departments, and every one of them assumes somebody else is doing the work.

• Where does the week go when you work alone?

  Into the hours nobody pays for: email, scheduling, invoices, notes, finding the next client and keeping up with your field. Most people who work alone guess too low until they count. Count one ordinary week, hour by hour, and you’ll know which of those hours to cut first.

• How much admin is normal for a practice of one?

  Less than you have, almost certainly. A few hours a week covers email, notes and the books once booking, payment and invoices run by themselves. If admin takes a day a week or more, something you do by hand could be done by the client or by software.

• When should a practice of one hire help?

  Later than you think, and for the work only you find tedious, not the work only you can do. First cut the admin that software or the client can do. Then, if you’re still turning clients away, hire a few hours a week of help for one job, usually bookkeeping or editing, before anything else.

• How much should you set aside for tax?

  A share of every payment, moved aside the day it lands. 25% is a common place to start in the US and the UK; on a $180 session that’s $45. Last year’s tax as a share of last year’s profit is the better number, once you have a year behind you.

• What records does your accountant need at year end?

  What came in, what went out, and the proof of both: every invoice and payment, the card fees taken from them, your payouts to the bank, your business costs with receipts, and anything you paid toward tax during the year. Hand it over in one place, sorted by month, and the bill gets smaller.

• Should you have a separate bank account for your practice?

  Yes, from the first payment. One account for the practice and a second for the tax you’ve set aside. In most places a sole proprietor or sole trader isn’t required to, but mixing the money makes every year-end slower, every tax question harder, and every good month look better than it was.

• What software does a practice of one need?

  Four things: one page that takes bookings, payment and your agreement; the calendar you already use; email; and an accountant, or software they recommend for your costs. Most practices of one run on more than that, and pay for it twice: once in subscriptions and once in the hours spent joining them up.

• How do you switch booking tools without losing clients?

  Run both for a month. Set up the new one, move your future availability there, and keep the old one only for sessions already booked. Change the link everywhere it appears, tell clients once, and close the old account when the last old booking has happened.

• What do the words of a practice of one mean?

  Retainer, day rate, deposit, package window, statement of work, engagement letter, set-aside: the words that come up once you work for yourself, each in a line. Most of them describe how you’re paid and what you’ve promised, so knowing them makes a conversation with a client shorter.
