books and expenses

Your books, expenses and records, and what the mess is costing you

Nobody starts a business to keep records, so the records slide. Here is how that shows up, why it happens, and the smallest habit that fixes each one.

Read the headings first. If one sounds like you, tick the signs underneath that fit your own business. Recognising the problem is the first step, and for some of these it is most of the work.

Small expenses are not worth recording.

Starting out with one account is convenient, and separating them never feels urgent until tax time.

Is this you?

Why it happens

Costs and time are tracked for the business as a whole, never per job, so the unprofitable work hides inside the total.

My accountant sorts it out at year end.

Is this you?

Why it happens

Handing the books to a professional feels like handling them, and it leaves eleven months without any view of the business.

Start with the expenses you are not recording

Mileage is the one most owners leave on the table. Work out what yours is worth. If receipts are the mess, Billbooks lets you log each expense with a photo of its receipt as you go, so there is no shoebox to sort at year end.
