When the current settlement period is reached, the settlement device counts the actual invoicing amount in the current settlement period and sends the actual invoicing amount to the invoicing device, and the actual invoicing amount is different from the estimated invoicing amount in the S201. The actual invoicing amount may be greater than the estimated invoicing amount or less than the estimated invoicing amount. For example: the actual invoicing amount is 14W, and the estimated invoicing amount is 10W.
And S204, determining the billing difference according to the difference between the actual billing amount and the estimated billing amount.
And S205, making a differential electronic invoice according to the billing differential.
And when the estimated invoicing amount is smaller than the actual invoicing amount, generating a difference electronic invoice according to the estimated electronic invoice and the invoicing difference.
For example: the estimated invoicing amount is 10W, the actual invoicing amount is 14W, the actual invoicing amount is larger than the estimated invoicing amount, the invoicing difference between the actual invoicing amount and the estimated invoicing amount is 4W, the preset maximum invoicing amount is 5W, whether the 4W is larger than the preset maximum invoicing amount is judged, and if yes, a difference electronic invoice is directly generated according to the invoicing difference 4W; if not, issuing a plurality of differential electronic invoices according to the invoicing differential, wherein the sum of the plurality of differential electronic invoices can be equal.
When the estimated invoicing amount is smaller than the actual invoicing amount, generating a difference electronic invoice according to the estimated electronic invoice and the invoicing difference; or
And when the estimated invoicing amount is larger than the actual invoicing amount, generating a difference electronic invoice according to the invoicing difference.
For example: the estimated invoicing amount is 10W, the actual invoicing amount is 9.5W, the invoicing difference between the estimated invoicing amount and the actual invoicing amount is 0.5W, the estimated invoicing amount is larger than the actual invoicing amount, the invoicing equipment selects one electronic invoice from the estimated invoicing amount, the electronic invoice is regenerated after the amount of the selected electronic invoice is subtracted by 0.5W from the invoicing difference, the regenerated electronic invoice is only different from the electronic invoice selected before in the invoicing amount, and other invoicing information is the same.
And S206, generating a settlement electronic invoice corresponding to the current settlement period according to the difference electronic invoice and the pre-estimated electronic invoice.
The billing equipment generates a settlement electronic invoice corresponding to the current settlement period according to the difference electronic invoice and the pre-estimated electronic invoice, the settlement electronic invoice comprises one or more pre-estimated electronic invoices and the difference electronic invoice, the billing equipment can send a download link of the settlement electronic invoice to the settlement equipment, and the settlement equipment downloads the settlement electronic invoice according to the download link.
