When you’re providing services like photography, copywriting, design, consulting, programming or marketing, it’s important to get your invoice over to the customer fast. We’re not saying you have to invoice them before the work has started or when the work is ongoing, but you’ll be surprised to know that many freelancers leave it quite late, causing problems in the long run.
Most businesses will have their own way of approving invoices and one process may involve several people before it’s approved and finally paid, especially if there is a finance department. This is why you should always send an invoice when the work is complete and approved, so waste no time in getting it over. The sooner they have it, the sooner the money will be in your bank account. You only have yourself to blame if you leave it too late.
