Most owners do their own books for longer than they should, and the reason is rarely cost. It is that the handover feels like more work than continuing, and no single month ever makes the case on its own.
The three signals
- You are doing it at night or on Sunday. That is not free, it is the most expensive labour in the business, priced at whatever you would otherwise have earned or rested.
- The numbers arrive too late to act on. Books closed in April for February inform nothing. Decisions get made on instinct while the answer sits unfinished.
- You have started avoiding it. Avoidance compounds. A month behind is an afternoon; six months behind is a project.
What it actually costs to be wrong
The visible cost of an error is the correction. The real costs are quieter: input tax credits never claimed, a receivable nobody chased into a write-off, a pricing decision made against a margin that was two points off, a year end that takes three extra weeks of an accountant's time billed hourly.
The middle option most people miss
It does not have to be all or nothing. Keeping receipt capture and invoicing in-house while handing over categorisation, reconciliation and reporting is a common split, costs less than full service, and removes the part that actually causes the delay.
