Building a Cash Buffer for Slow Periods
4 November 2026 · By Heaney Accounting
The nature of trade work often means you have months where you are flat out, followed by weeks where the phone stops ringing. Many business owners make the mistake of spending their cash surplus during the busy times on new gear or fancy upgrades. Instead, you should aim to tuck away a percentage of every invoice into a separate high-interest business savings account to create a safety net for future downtime.
A good target is to build up three months of core operating expenses as your emergency buffer. This includes your rent, insurance, software subscriptions, and minimum loan repayments. Having this amount sitting in a separate account means that when a project gets delayed or a client is slow to pay, you are not scrambling to find cash to keep the lights on.
Beyond just surviving, a cash buffer provides you with the power to say no to low-margin or bad-fit projects. When you are desperate for cash, you tend to take on work that actually costs you money or causes you unnecessary stress. With a reserve in the bank, you can afford to hold out for better, more profitable contracts that align with your long-term growth goals.
Finally, make your savings automatic so you do not have to rely on willpower. Set up a standing transfer for a fixed percentage of every customer payment to hit your savings account immediately upon receipt. Treat this transfer like any other fixed business cost, and over time, you will find your financial resilience grows alongside your reputation for quality work.
