I was thinking about maintenance. I take on board that if your really busy you don't need to consider it, however I see potential in it if your looking to expand and ensure all your staff have work all year, it may help. I was thinking of offering a monthly direct debit fee for maintenance, where you do a biocide wash in spring, weedkiller in autumn, resend any points that need it, gutter clean, if you do there roof, weak biocide annually. TBH i've not thought it through or how much I would charge or if its even viabe, however its a good business model to retain customers that is used in other industries and ensures residual money/cash flow all year. Essentially they will be paying for work before you have even done it.
