Great! I had never made documents interactive before so I had no idea what I was doing. This was so easy to use. I really just needed it for a few documents so there was no reason to keep the subscription. If I needed it though I would not even hesitate to pay for it.

Make every invoice number unique you can start from any number you want. Assign sequential invoice numbers. Assign invoice numbers in chronological way. Structure invoice numbers any way you want, you may: use only numbers 001, 002, 003 etc., include Customer Name CN001, CN002, etc.
An invoice number is a unique, sequential code that is systematically assigned to invoices. Invoice numbers are one of the most important aspects of invoicing as they ensure that income is properly documented for tax and accounting purposes. They also make it easier to track payments.
Chronological Invoice Numbering The first series of numbers is the date, the second series of numbers is the customer number and the third series of numbers is the sequential unique identifier for the invoice. If you generate a second invoice on that date for that customer, the invoice number will be 20170630-4072-01.
An order number is a VA number by which to charge the ordered goods. The invoice number is the vendor's number for billing the ordered goods.
Definition: An invoice is a document issued by a seller to the buyer that indicates the quantities and costs of the products or services provider by the seller. Payment terms indicate the maximum amount of time that a buyer has to pay for the goods and/or services that they have purchased from the seller.
Invoices — what they must include Your invoice must include: a unique identification number. Your company name, address and contact information. The company name and address of the customer you're invoicing.
Each invoice issued should be assigned a unique invoice number. The invoice number should always be clearly stated on the invoice without an invoice number, an invoice is not considered a legal document. As proforma invoices are not 'true' invoices, they should not be given invoice numbers.
Sequential invoice numbering is the foundation for creating distinctive invoice numbers. The invoice numbering starts with the number 1 unless you override it. For example, if you prefer a five-digit invoice number, you can replace the 1 with the number, 10,000.
