A Diary Rules Sheet for a One-Person Firm: Which Days and Times Are Bookable

When someone else takes bookings for you, they can only work from what the diary shows. It shows free space. It doesn't know that a certain job always overruns, or that you won't start a messy first-fix on a Monday morning. A one-page rules sheet fills that gap.

This article gives you a layout for that sheet. For a fuller walkthrough of the thinking behind it, there is a guide on setting diary rules for someone else to follow. What follows is a practical template you can fill in over a cup of tea.

Section 1: The "never" list

Start with what you would refuse if you were answering the phone yourself. Most sole traders hold more unwritten rules than they realise. Write each one as a plain sentence:

• Areas or postcodes you won't travel to
• Work you don't do, or only do for existing customers
• Days kept clear for paperwork, stock runs or time off
• Start times you can't reach because of school runs or travel from the previous job

If a rule needs a reason, add it in a few words. "No new customers on Fridays, because Fridays are for finishing jobs off" lets the person booking handle a case you never thought of.

Section 2: Job types in three groups

Not every enquiry deserves the same treatment. Sort your usual jobs into three lists.

Book freely. Short, predictable, repeatable jobs where you know roughly how long they take. These can go into any open slot that fits your day rules.

Book with conditions. Jobs that are fine as long as something is true: the address is inside your area, the customer has confirmed access, or the job is first of the day so an overrun doesn't spill into the next one. Write the condition as something the booker can actually check.

Take details, don't book. Large quotes, anything needing a visit before you can price it, and anything unusual. The booker captures the address, the problem and the best time to call back. You choose the slot.

Section 3: The shape of your week

Avoid "whenever I'm free". Describe the week as a pattern instead. A simple table works well, with a row for each day and columns for open hours, protected hours and notes.

Things to settle:

• Protected time. Block any hours you want kept clear so they never show as available. If the diary tool can't hide them, mark them as busy.
• Buffers. Decide how much gap goes between bookings for travel and overruns. If the diary shows back-to-back slots, someone will use them.
• Short-notice rules. Say whether same-day and next-day bookings are allowed, and for which job types. You might allow them only for the "book freely" group.
• Earliest and latest starts. Give actual times, and say whether they apply to every job type or just some.

Section 4: What to do when a request doesn't fit

The sheet will never cover everything, so give the booker a fallback. Keep it short:

1. Don't say yes or no to anything not on the sheet.
2. Take the customer's name, number, address and a description of the job.
3. Tell them when you'll call back, and mean it.

Also say how you want to be reached for genuine emergencies, and what counts as one. Without that, every call becomes urgent or none do.

Section 5: Changes and cancellations

Decide who may move or cancel a booking, and what they should do when it happens. If a customer cancels, should the gap be offered to someone on a waiting list, or left alone so you can catch up? Write down which one. Also say who tells you about changes and how, whether a text, a note in the diary or an end-of-day message.

Keeping the sheet useful

• Keep it to one page. If it runs longer, people stop reading it. Move detail into a separate notes list.
• Use your own words. "No tight turnarounds after a big job" is fine if the booker knows what a big job is, so add examples.
• Test it. Hand the sheet to someone and give them three or four made-up enquiries. Where they hesitate, the sheet has a gap.
• Update it when a booking goes wrong. Every awkward double-booking points to a missing rule. Add it that day while you remember why.

If the booker is software, the same sheet still helps. Your sections translate directly into availability windows, buffer settings and job-type options, and the "take details" group becomes an enquiry form rather than a bookable slot.

A good rules sheet doesn't make you less flexible. It lets you decide once, in writing, and stops you making the same decision on the phone every time someone asks.
