Work Smarter – Not Harder

zistemo Tips & Tricks

Invoicing is a crucial aspect of your financial record keeping – and one that can have many implications if it is done incorrectly. Your customers expect a rational invoice system that their accounting departments can readily identify and your auditors expect a clear paper trail. can help you get all the details in place and stay on track through the accounting cycle to make the whole job easier.

Where to start?

While you can begin with the number 0000001 - many people feel there is a kind of psychological disadvantage; it’s an obvious sign of a new business or at the very least a new system. On, you can choose any starting 7-digit number and will automatically increment based on that number. For example, if you choose 0020405, the next number will be 0020406, then 0020407 and so on. can also make sure that you don’t skip any numbers in a sequence. Simply adjust the settings under Strict Invoice Sequences and you’ll avoid any numerical gaps. We strongly recommend this course of action. Some jurisdictions globally do not require strict adherence to a numerical sequence - i.e. 0000001, 0000002, 0000003 as opposed to 0000001, 0000004, 0000033… - however in the case of an audit, you may find that you will have to provide additional proof that the gaps don’t simply represent lost or otherwise unaccounted for invoices by means of bank statements and other documentation. Keeping a strict sequence of numbers can save you trouble and wasted time down the road.
