s201, predicting the estimated billing amount of the current settlement period before the current settlement period.
The settlement period may be determined by a settlement device, the settlement device periodically performs settlement, and the duration of the settlement period may be determined according to actual requirements, which is not limited in the embodiment of the present application, for example: the settlement period is each time of a week, each time of a month or each time of a quarter, etc. Before the current settlement period, the billing apparatus predicts an estimated billing amount for the current settlement period, for example: the settlement period is one month each time, the current settlement period is 11 months, before the end of 11 months, the billing equipment predicts the estimated billing amount of 11 months, obviously the estimated billing amount is inaccurate, and a certain difference exists between the estimated billing amount and the actual billing amount of 11 months. Alternatively, the estimated amount of the invoice may take the form of a 2-bit decimal.
In one possible embodiment, the billing apparatus predicts an estimated billing amount for a current settlement period, including:
and predicting the estimated billing amount of the current settlement period according to the actual billing amounts of the plurality of historical settlement periods.
The billing equipment can carry out weighted average on the actual billing amount of a plurality of historical settlement periods to obtain the estimated billing amount of the current settlement period.
For example: the current settlement period is 11 months, and the actual billing amount of 1 month to 10 months before 11 months is obtained by billing equipment is as follows: the estimated invoicing amount obtained by arithmetic averaging of the actual invoicing amount of 1 month to 10 months by the invoicing device is 10 ten thousand, 11 ten thousand, 12 ten thousand, 14 ten thousand, 10 ten thousand, 9 ten thousand, 12 ten thousand, 10 ten thousand and 11 ten thousand: 12.3W.
Further, the predicted billing amount is a positive integer multiple of the maximum billing amount, and the billing device performs downward rounding on the billing amount obtained by the weighted average to obtain the maximum billing amount of the positive integer multiple.
For example: the maximum billing amount is 5W, the billing amount after weighted averaging is 12.3W, and the 12.3W is rounded down to be a positive integer multiple of 5W to be 2, namely the estimated billing amount is 2×5w=10w.
S202, issuing a predicted electronic invoice according to the predicted invoice amount.
The billing equipment generates a predicted electronic invoice according to the predicted billing amount, commodity names, commodity quantity, information of both sides of purchase and sale and the like, and the estimated amount of the electronic invoice is the predicted billing amount. The format of the estimated electronic invoice can be PDF format, and the billing equipment can send a download link of the estimated electronic invoice to the settlement equipment so that the settlement equipment can download the estimated electronic invoice according to the download link.
Further, the number of the estimated electronic invoices is one or more, and when the number of the estimated electronic invoices is multiple, the invoicing amount of each estimated electronic invoice is equal. The billing amount of each estimated electronic invoice can be equal to a preset maximum billing amount.
For example: the maximum invoicing amount is 5W, and the estimated electronic invoice comprises 3 electronic invoices with the invoicing amount of 5W.
S203, receiving the actual billing amount in the current settlement period.
When the current settlement period arrives, the settlement device counts the actual billing amount in the current settlement period, and sends the actual billing amount to the billing device, wherein the actual billing amount is different from the estimated billing amount in S201. The actual amount of the invoice may be greater than the estimated amount of the invoice or may be less than the estimated amount of the invoice. For example: the actual billing amount is 14W, and the estimated billing amount is 10W.
S204, determining the billing difference according to the difference between the actual billing amount and the estimated billing amount.
S205, issuing a balance electronic invoice according to the invoicing balance.
And when the estimated invoicing amount is smaller than the actual invoicing amount, generating a differential electronic invoice according to the estimated electronic invoice and the invoicing differential.
For example: the estimated billing amount is 10W, the actual billing amount is 14W, the actual billing amount is larger than the estimated billing amount, the billing difference between the actual billing amount and the estimated billing amount is 4W, the preset maximum billing amount is 5W, whether 4W is larger than the preset maximum billing amount 5W is judged, and if yes, a difference electronic invoice is directly generated according to the billing difference 4W; if not, a plurality of differential electronic invoices are issued according to the invoicing differential, and the amounts of the 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 (b)
And when the estimated invoicing amount is larger than the actual invoicing amount, generating a differential electronic invoice according to the invoicing differential.
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 subtracting the invoicing difference by 0.5W from the selected electronic invoice, the regenerated electronic invoice is different from the electronic invoice selected before, and other invoicing information is the same.
S206, generating a settlement electronic invoice corresponding to the current settlement period according to the balance electronic invoice and the estimated electronic invoice.
The billing equipment generates a settlement electronic invoice corresponding to the current settlement period according to the balance electronic invoice and the estimated electronic invoice, wherein the settlement electronic invoice comprises one or more estimated electronic invoices and the balance 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.
Further, the billing device obtains a digital certificate distributed by the tax system, the digital certificate comprises a public key, the billing device generates a private key according to the public key, the private key is used for signing the electronic invoice to obtain an electronic signature, the electronic signature and the electronic invoice are sent to the settlement device, the settlement device receives the electronic invoice from the billing device, firstly, the public key in the digital certificate distributed by the financial system is used for checking the electronic signature, after the checking is passed, the settlement device checks the received electronic invoice according to the actual settlement amount in the current settlement period, when the billing amount of the digital certificate and other billing information are matched, the electronic invoice is stored in the financial system, and the financial system is used for recording financial data and can be a database.
When the scheme of the embodiment of the application is executed, after the settlement device sends the actual invoicing amount of the current settlement period to the invoicing device, the invoicing device issues the estimated electronic invoice in advance according to the estimated invoicing amount, the invoicing device subtracts the invoicing difference obtained by the estimated invoicing amount from the actual invoicing amount so as to supplement the electronic invoice with the difference, the purpose of splitting the electronic invoice according to the actual invoicing amount is achieved, and the fact that the actual invoicing amount is matched with the sum of the amounts of the estimated electronic invoice and the electronic invoice with the difference is ensured. According to the method and the device for issuing the electronic invoice, the problems that the issuing information of the electronic invoice is wrong and the efficiency is low due to manual issuing can be avoided, and the efficiency of issuing the electronic invoice and the accuracy of issuing the invoice can be improved through the mode of pre-issuing the pre-estimated electronic invoice and the additional issuing the differential electronic invoice.
