Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that
Detailed description of the invention described herein is merely to illustrate and explains the present invention, is not limited to this
Bright.
The commodity detail tax rate that many tax rates refer on a VAT invoice can be multiple；Containing the amount of tax to be paid
Sales slip is the one of enterprise marketing list, according to the needs of financial management, enterprise before invoice issuing the most
Through having calculated the amount of tax to be paid of this sales slip in sales slip.The feature of this sales slip data is to sell
Single master data does not identify the tax rate, but identifies the amount of tax to be paid；Sales slip detailed data both identified multiple
The tax rate, also identifies the amount of tax to be paid.
As it is shown in figure 1, according to one embodiment of the present invention for the sales slip containing the amount of tax to be paid open many tax rates increase
The method of value tax invoice comprises the following steps:
Step S1, the sales slip data set obtaining ticket to be developed and sales slip detailed data collection, sales slip
Data set include the sales slip amount of money, the sales slip amount of tax to be paid, containing tax mark and limit of making out an invoice, sales slip detail number
Include that multiple commodity detail row, each commodity detail row include trade name, unit price, quantity, gold according to collection
Volume, the amount of tax to be paid and the tax rate.
Generally, in the operation system of enterprise, add mark of making out an invoice can to the sales slip in sales slip tables of data
Will, in order to clearly search and process the sales slip not issued invoice.Therefore, it can according to sales slip
" mark of making out an invoice ", the sales slip tables of data of enterprise operation system is searched the sale not issued invoice
Single key data, forms sales slip data set.It is for instance possible to use SQL statement or other computers
Program statement obtains sales slip data set, and exemplary SQL statement form is: " SELECT sells
Odd numbers, the sales slip amount of money, the sales slip amount of tax to be paid, containing tax mark, inventory mark, Chinese character anti-false logo,
Limit FROM of making out an invoice sales slip tables of data WHERE is made out an invoice mark=' not making out an invoice ' ".Above SQL
Sentence format is only exemplary, and in practical operation, inventory mark and Chinese character anti-false logo are not
Must obtain, namely in sales slip data set, not include inventory mark and Chinese character anti-false logo
In the case of, can follow-up sales slip detailed data collection is split time, pre-by VAT invoice
Determine commodity detail line number and be defined to such as 7 row (this changes according to the VAT invoice of tax bureau's offer),
So that the limit that the commodity detail line number maximum that each ticket data to be developed is concentrated specifies less than the tax bureau
Condition processed.Table 1 gives exemplary sales slip data set.
Table 1
Furthermore it is possible to use SQL statement or other computer program statements to obtain sales slip detail number
According to collection, exemplary SQL statement form is: " SELECT sequence number, trade name, by discount mark,
Discount ratio, unit price, quantity, the amount of money, the tax rate, amount of tax to be paid FROM sales slip commodity detailed data table
WHERE sells odd numbers=' present sales odd numbers ' ".Wherein, by discount mark and discount ratio it is not
Necessary, when enterprise does not carries out discount sales to commodity, sales slip detailed data is concentrated and can not be included
By discount mark and discount ratio.Table 2 shows the exemplary sales of the sales slip XSD0001 of table 1
Single detailed data collection.It addition, when there being discounting commodity, before the amount of tax to be paid in table 2 is based on the discount of commodity
The amount of tax to be paid that the amount of money calculates.
| Sequence number | Trade name | Unit price | Quantity | The amount of money | The tax rate | The amount of tax to be paid | By discount mark | Discount ratio |
| 1 | Commodity 1 | 1000.00 | 1 | 1000.00 | 11% | 99.10 | ||
| 2 | Commodity 2 | 750.00 | 2 | 1500.00 | 6% | 84.91 | ||
| 3 | Discounting commodity 1 | 300.00 | 2 | 600.00 | 11% | 59.46 | Y | 20% |
| 4 | Discounting commodity 2 | 400.00 | 1 | 400.00 | 11% | 39.64 | Y | 20% |
| 5 | Commodity 3 | 700.00 | 2 | 1400.00 | 11% | 138.74 | ||
| 6 | Commodity 4 | 400.00 | 4 | 1600.00 | 6% | 90.57 | ||
| 7 | Discounting commodity 3 | 400.00 | 13 | 5200.00 | 6% | 294.34 | Y | 20% |
| 8 | Discounting commodity 4 | 600.00 | 3 | 1800.00 | 6% | 101.89 | Y | 20% |
| 9 | Commodity 5 | 500.00 | 5 | 2500.00 | 11% | 247.75 |
Table 2
Step S2, whether verify in each commodity detail row the product of unit price and quantity equal to same commodity
The amount of money in detailed row, verifies whether the amount of money sum in all commodity detail row is equal to the sales slip amount of money,
With the amount of tax to be paid sum verified in all commodity detail row whether equal to the sales slip amount of tax to be paid.
Such as, in verifying each commodity detail row, unit price is the brightest equal to same commodity with the product of quantity
Carefully during the amount of money in row, can concentrate at sales slip detailed data, circulate to end data from first bar, by
Bar obtains these data item of line number, the amount of money, quantity and unit price of every commodity detail row, and calculates " single
Valency * quantity ", it is judged that result of calculation is the most equal with the amount of money in this commodity detail row, if unequal,
Then point out such as " line number be ' current line number ' sales slip detailed data concentrate, unit price * quantity with gold
Volume is unequal ", and terminate algorithm flow；If equal, then continue subsequent step.
When whether the amount of money sum in verifying all commodity detail row is equal to the sales slip amount of money, can be at pin
Sell single detailed data to concentrate, from first bar to end data circulation, obtain the gold of every commodity detail row one by one
Volume data item, accumulative addition calculation generates detailed Amount in Total, and judges this detail Amount in Total and sale
Single amount of money is the most equal, if unequal, then points out such as " the ∑ sales slip detail amount of money and sales slip gold
Volume is unequal " after, terminate algorithm flow；If equal, then continue subsequent step.
When whether the amount of tax to be paid sum in verifying all commodity detail row is equal to the sales slip amount of tax to be paid, can be at pin
Sell single detailed data to concentrate, from first bar to end data circulation, obtain one by one in each commodity detail row
Amount of tax to be paid data item, accumulative addition calculation generates detail and adds up to the amount of tax to be paid, finally judge this detail add up to the amount of tax to be paid and
The sales slip amount of tax to be paid is the most equal, if unequal, then prompting " the ∑ sales slip detail amount of tax to be paid and sales slip tax
Volume is unequal " after, terminate algorithm flow；If equal, then continue subsequent step.
Step S3, basis calculate containing the unit price in tax mark, each commodity detail row, quantity and the tax rate
And in each commodity detail row, add valency tax total, invoice amount, the invoice amount of tax to be paid and invoice unit price, and
The valency tax of all commodity detail row of adding up respectively adds up to, invoice amount and the invoice amount of tax to be paid be with detailed at sales slip
Data set adds detail total valency tax total, detailed total invoice amount and the detailed total invoice amount of tax to be paid.
Wherein, in the case of the mark containing tax represents containing tax (such as, representing containing tax with letter Y) (also
I.e. unit price in commodity detail row is containing duty receipt valency), use below equation to calculate each commodity detail row
Valency tax total, invoice amount, the invoice amount of tax to be paid and invoice unit price:
Valency tax total=unit price * quantity；
Invoice amount=valency tax adds up to/(the 1+ tax rate)；
The invoice amount of tax to be paid=valency tax total-invoice amount；
Invoice unit price=unit price/(the 1+ tax rate)；
In the case of the mark containing tax represents without tax (such as, representing containing tax with letter N) (namely business
Unit price in product detail row is free from duty receipt valency), use below equation to calculate the valency of each commodity detail row
Tax total, invoice amount, the invoice amount of tax to be paid and invoice unit price:
Invoice amount=unit price * quantity；
The invoice amount of tax to be paid=invoice amount * tax rate；
Valency tax total=invoice amount+invoice amount of tax to be paid.
Calculate valency tax total, invoice amount, the invoice amount of tax to be paid and the invoice unit price of each commodity detail row with
And detailed total valency tax add up to, detailed add up to invoice amount and detailed add up to after the invoice amount of tax to be paid exemplary
Table 4 hereinafter asked for an interview by sales slip detailed data collection.
Whether the absolute value of the difference of step S4, the amount of tax to be paid verified in each commodity detail row and the invoice amount of tax to be paid
Less than the first predetermined value.
Such as, in this step, each commodity detail row data that sales slip detailed data is concentrated, from
First bar calculates the amount of tax to be paid error of each commodity detail row one by one to end bar circulation, and formula is: amount of tax to be paid error=
The amount of tax to be paid-invoice amount of tax to be paid, if | amount of tax to be paid error | > the first predetermined value, then the range of error beyond regulation can not
Make out an invoice, after prompting " line number is that the commodity detail amount of tax to be paid of ' current line number ' surpasses error, it is impossible to make out an invoice ",
Terminate algorithm flow, if < the first predetermined value then continues subsequent step to | amount of tax to be paid error |.Preferably,
One predetermined value is the 0.06 of revenue department's regulation, certainly selects the value less than 0.06 as the first predetermined value also
It is feasible.
Step S5, according to making out an invoice the predetermined commodity detail line number on limit and VAT invoice, will sell
Single detailed data collection splits into multiple ticket data collection to be developed.
Limit of making out an invoice is the restriction to the amount of money of making out an invoice, the VAT invoice of such as 10,000 yuan, the highest opens
The ticket amount of money is 10,000 yuan.Predetermined commodity detail line number on VAT invoice is that enterprise can send out at value-added tax
The maximum commodity detail line number listed on ticket.That is, each ticket data collection to be developed finally given is bright
Thin total invoice amount can not be more than making out an invoice limit, and its commodity detail line number not can exceed that on VAT invoice
Predetermined commodity detail line number.Split the ticket data collection exemplary to be developed obtained and ask for an interview table 5 hereinafter
With table 6.
So far, just completing the process of sales slip data, the ticket data collection each to be developed generated is exactly
The key data of one ticket to be developed, other number needed drawing a bill in these key datas and sales slip
Complete sending out can be formed according to key element (such as, sales organization, purchasing unit title etc.) after merging
Ticket data, the interface that the invoice data that this is complete is sent to tax-supervise system to be provided just can complete invoice
Open.
Preferably, sales slip data set can also include inventory mark and Chinese character anti-false logo, should
Chinese character anti-false logo defines the predetermined commodity detail line number on VAT invoice.Wherein, inventory mark
Will for representing whether the VAT invoice opening band inventory, such as, can represent with inventory mark Y
Open the VAT invoice of band inventory, represent with inventory mark N and open the VAT invoice without inventory.
Chinese character anti-false logo illustrates enterprise's registration type in Administration of State Bureau, such as, can look forward to Chinese character anti-false
Industry mark Y represents that this enterprise is Chinese character anti-false enterprise, represents this enterprise with Chinese character anti-false logo N
Shi Fei Chinese character anti-false enterprise.Opening regulation according to existing Administration of State Bureau VAT invoice, non-Chinese character anti-false is looked forward to
The commodity detail line number that industry is opened on VAT invoice not can exceed that 8, and Chinese character anti-false enterprise is in increment
The commodity detail line number opened on tax invoice not can exceed that 7.Then:
(1) in the case of inventory mark represents and opens the VAT invoice of band inventory, abovementioned steps S4
Also include that the amount of tax to be paid sum verifying in all commodity detail row and detail add up to the exhausted of the difference of the invoice amount of tax to be paid
To value whether less than the second predetermined value, namely verification | detailed total invoice amount of tax to be paid detail adds up to the amount of tax to be paid |
Whether less than the second predetermined value, if less than, continue subsequent step, if being more than, then point out such as and " sell
Single amount of tax to be paid surpasses error, it is impossible to make out an invoice " after, terminate algorithm flow.Preferably, the second predetermined value is the tax
The 1.27 of agencies dictate, certainly, selecting the value less than 1.27 is also feasible as the second predetermined value.With
And, step S5 includes, according to limit of making out an invoice, sales slip detailed data collection is split into multiple poll to be developed
According to collection, the most each ticket data collection to be developed detailed add up to invoice amount be less than or equal to described in make out an invoice limit
Volume.Owing to being the VAT invoice opening band inventory, it is possible to do not consider Chinese character anti-false logo.
Such as, this step can be carried out as follows: first, it is determined that send out detailed total that sales slip detailed data is concentrated
The ticket amount of money, whether less than or equal to making out an invoice limit, if being less than or equal to, does not the most split sales slip detailed data collection；
If being more than, then need sales slip detailed data collection to be split, i.e. from sales slip detailed data to be split
Concentrate, successively from first bar commodity detail row to end bar commodity detail row circulation, take in every commodity detail row
Invoice amount and its Amount in Total of accumulation calculating, obtained when accumulation calculating to certain commodity detail row
Amount in Total more than make out an invoice limit time, by before this commodity detail row entire service detail row split
Concentrating to a ticket data to be developed, the rest may be inferred, sales slip detailed data collection is split into multiple and waits out
Invoice data collection so that the detailed total invoice amount that each ticket data to be developed is concentrated is not more than invoice limit
Volume.
(2) in the case of inventory mark represents and opens without the VAT invoice of inventory, abovementioned steps
S5 includes: according to making out an invoice limit and sales slip detailed data collection is split into many by Chinese character anti-false logo
Individual ticket data collection to be developed, the detailed of the most each ticket data collection to be developed adds up to invoice amount to be less than or equal to
It is pre-that the commodity detail line number of limit of making out an invoice and each ticket data collection to be developed is not more than on VAT invoice
Determine commodity detail line number.That is, non-Chinese character anti-false enterprise at most can only open 8 on VAT invoice
Commodity detail line number, Chinese character anti-false enterprise at most can only open 7 commodity detail row on VAT invoice
Number.
It addition, when enterprise is to its commodity discount sales, will be in the sales slip detailed data table of enterprise
Have by discount mark and discount ratio the two data item, to show which commodity is discounting commodity, give a discount
Ratio is how many, consequently facilitating the financial management of enterprise.It is therefore preferred that sales slip detailed data collection
Each commodity detail row in also include by discount mark and discount ratio, and after the sales slip amount of money is discount
The amount of money, the sales slip amount of tax to be paid is also for consider the amount of tax to be paid after discount, and the amount of money in each commodity detail row is
The amount of money before discount, the amount of tax to be paid in each commodity detail row is the amount of tax to be paid calculated according to the amount of money before discount, so:
In aforesaid step S2, it is necessary to utilize after discount amount of money * (1-discount rate before the amount of money=discount
Example) calculate the discount of the commodity detail row comprising discount commodity after the amount of money and after verifying this discount the amount of money with
Whether do not comprise the amount of money sum in other commodity detail row of discount commodity equal to the sales slip amount of money.Namely
When having discounting commodity in the sales slip detailed data table of enterprise, need first to calculate this commodity detail row
After discount, the amount of money adds up the most again.And, in step s 2, the most correspondingly need first to calculate bag
After the discount of the commodity detail row containing discount commodity the amount of tax to be paid and after verifying this discount the amount of tax to be paid with do not comprise discount
Whether the amount of tax to be paid sum in other commodity detail row of commodity is equal to the sales slip amount of tax to be paid.After discount, the amount of tax to be paid is permissible
Calculate according to the amount of money after discount and the mark Han tax.
And, in aforesaid step S3, concentrate each commodity detailed calculating sales slip detailed data
Before valency tax total, invoice amount, the invoice amount of tax to be paid and the invoice unit price of row, in addition it is also necessary to according to discount ratio
Rearrange each commodity detail row with the tax rate, calculate and there are identical discount ratio and the commodity of same tax rate
Detailed total line number of row, total discount amount and total discount amount of tax to be paid, and there is identical discount ratio with identical
A discount row is inserted after last column commodity detail row of the commodity detail row of the tax rate, this discount row
Trade name embodies total line number of the commodity detail row with identical discount ratio and same tax rate with
And discount ratio, the amount of money of this discount row is total discount amount * (-1), and the amount of tax to be paid of this discount row is described
Total discount amount of tax to be paid * (-1).For example, it is possible to the commodity detail row of identical discount ratio and same tax rate is divided
At one group, and being arranged in order by group, discount ratio is one group of empty business represented in this group commodity detail row
Product are non-discounting commodity, this group commodity detail row can be arranged in foremost and (certainly, come sales slip
Detailed data collection is the most also feasible)；It is not empty each group commodity detail row to discount ratio,
Need to add up respectively total line number of each group of commodity detail row, calculate total discount amount of each group of commodity detail row
With total discount amount of tax to be paid, the wherein amount of money * discount ratio in total this group commodity detail row of discount amount=∑, always
The discount amount of tax to be paid can be according to containing tax mark, calculate by aforesaid invoice computation of tax amount formula, and respectively
A discount row, the commodity of this discount row are inserted after last column commodity detail row of group commodity detail row
Title can be " discount line number Y (X.XXX%) ", and wherein " Y " respectively organizes tool for what calculating generated
Having total line number of the commodity detail row of identical discount ratio and same tax rate, " X " is discount ratio, or
The trade name of this discount row can also be that other can embody this group and have identical discount ratio with identical
Total line number of the commodity detail row of the tax rate and other titles of discount ratio, the amount of money of this discount row is for calculating
Total discount amount * (-1) generated is to represent that commodity are given a discount.Table 3 gives in discount ratio and tax
Rate rearranges the commodity detail row in table 2 and inserts the exemplary sales list detailed data after discount row
Collection.
Table 3
Table 4 gives and calculates the valency tax total of each commodity detail row, invoice gold on the basis of table 3
Volume, the invoice amount of tax to be paid and invoice unit price and detailed total valency tax add up to, detail adds up to invoice amount and detail
Add up to the exemplary sales list detailed data collection after the invoice amount of tax to be paid.
Table 4
And, when sales slip detailed data concentration includes by discount mark and discount ratio, at inventory mark
In the case of will represents and opens without the VAT invoice of inventory, also need in step s 5 discount row
Process, ticket data the most to be developed concentrate have identical discount ratio and a line of same tax rate or
Discount row is not had then to do business this last after last column commodity detail row of multirow commodity detail row
Insert a discount row after product detail row and (wherein, insert the operation of discount row and insertion described before
The operation of discount row is identical, and here is omitted), if having after described last column commodity detail row
There is discount row then to update this discount row and (wherein, update the operation of discount row and insertion discount described before
The operation of row is identical, the most also repeats no more), and update the detailed conjunction that this ticket data to be developed is concentrated
Valuation tax adds up to, detail adds up to invoice amount and detail adds up to the invoice amount of tax to be paid.This makes it possible to treat every
The discount data drawn a bill in data set processes again, so that every ticket data to be developed concentration
Data are the most accurate, it is to avoid occur according to the amount of money on the invoice that this ticket data collection to be developed is opened, tax
The situation that the data item calculated in the sales slip of the data item such as volume and enterprise there are differences, improves enterprise
Financial Control Level.As a example by the sales slip detailed data collection of table 4, split utilizing this step
Obtain two ticket data collection to be developed afterwards, ask for an interview shown in table 5 and table 6.Clear due to what table 1 was given
Single mark is Y, namely opens the VAT invoice of band inventory, so only considering, when splitting, limit of making out an invoice
This factor is without considering Chinese character anti-false logo.
Table 5
Table 6
It addition, from the point of view of according to existing effective sale forms data statistical result, in the increment opening band inventory
In the case of tax invoice, the detailed total invoice amount that usual sales slip detailed data is concentrated is less than making out an invoice
Limit, therefore when sales slip detailed data concentration also includes discounting commodity, in the fractionation of step S5
During discount data can not be processed.If detailed total that sales slip detailed data is concentrated is sent out
The ticket amount of money is more than making out an invoice limit, then in the split process of step S5, can according to above-mentioned open without
In split process in the case of the VAT invoice of inventory, process will be for processing procedure to discount data
The discount data on inventory it is listed in when making out an invoice.
According to one embodiment of the present invention, the present invention also provides for one and opens many for the sales slip containing the amount of tax to be paid
The system of tax rate VAT invoice, this system include acquisition module 21, sales slip data check module 22,
Invoice data computing module 23, amount of tax to be paid error estimator module 24 and fractionation module 25.
Wherein, acquisition module 21, for obtaining sales slip data set and the sales slip detail number of ticket to be developed
