invoice generator

Summary

A simple api to create invoices in pdf format. Based on fpdf package.

Dependencies

Installation

go get -u github.com/buffos/go-aade/pdfinvoice

Usage

First, We need to set to environment variables to use the api.

  • FONT_PATH: The path to the fonts directory
  • LOGO_FILE_PATH: the path to the logo file (including the file name and extension)

In the default options struct, we are expecting the following font files:

`FONT_PATH`/Roboto-Regular.ttf
`FONT_PATH`/Roboto-Bold.ttf

Font files are not included

We create a document that holds the required data

doc, err := NewInvoice(nil)

If we pass nil as the options struct, the default options are used. You can view and create custom options. The options struct is defined in the options.go file.

Then we add data to the document.


doc.LogoFileName = os.Getenv("LOGO_FILE_PATH")
doc.SetIssuer(&Contact{
		Name:            "Κωνσταντίνος Παπαδόπουλος",
		AFM:             "090000000",
		WorkDescription: "Τίποτα Απολύτως",
		Address: &Address{
			Address:    "Εγνατίας 12",
			Address2:   "",
			City:       "Θεσσαλονίκη",
			PostalCode: "12345",
		},
		DOY:            "Α΄ ΘΕΣΣΑΛΟΝΙΚΗΣ",
		AdditionalInfo: []string{"ΓΕΜΗ: 231506418987897 · email: support@test.gr \nΤηλ: 2210000111 · Κιν: 697777777"},
	})
	doc.SetCustomer(&Contact{
		Name:            "Παπαδόπουλος Ανδρέας",
		AFM:             "090000000",
		WorkDescription: "Παροχή Υπηρεσιών",
		Address: &Address{
			Address:    "Τσιμισκή 12",
			Address2:   "",
			City:       "Θεσσαλονίκη",
			PostalCode: "12345",
		},
		DOY: "Β΄ Θεσσαλονίκης",
	})

doc.Type = "Τιμολόγιο Παροχής Υπηρεσιών"
doc.Series = "ΤΠΥ-Α"
doc.Number = "1"
doc.Date = "01/01/2021"
doc.Mark = "4000000012351351"
doc.PaymentMethod = "Μετρητά"
doc.Notes = `Η παραγγελία θα εκτελεσθεί μέχρι τις 24 Ιουνίου 2021. Αριθμός συναλλαγής 40909345`
doc.QRCodeString = "https://www.example.gr"

Now we need to add the invoice entries for each item. For example:

	doc.InvoiceDetails.AddEntry(&InvoiceEntry{
		Description:       "Παροχή υπηρεσιών κατασκευής ιστοσελίδας",
		Quantity:          1,
		UnitOfMeasurement: "",
		NetPrice:          100,
		Discount:          0,
		FinalPrice:        0,
		TaxPercent:        24,
		TaxAmount:         24,
	})
	doc.InvoiceDetails.AddEntry(&InvoiceEntry{
		Description:       "Παροχή συντήρηση ιστοσελίδας για ένα έτος.",
		Quantity:          1,
		UnitOfMeasurement: "",
		NetPrice:          100,
		Discount:          0,
		FinalPrice:        0,
		TaxPercent:        24,
		TaxAmount:         24,
	})

Call the doc.CalculateTotals() function to calculate the totals row of the invoice. Next, we need to complete the taxes entries.

	doc.Taxes.WithHoldingTaxes = 20
	doc.Taxes.Deductions = 0
	doc.Taxes.StampDuty = 0
	doc.Taxes.Fees = 0
	doc.Taxes.OtherTaxes = 0

Finally, we need to create the document.

err = doc.CreateAndSave("test.pdf", SimpleA4Invoice{})

The second argument is a struct that implements the InvoiceCreator interface. This interface has three functions that 'draw' the header, footer and middle part of the invoice using the data we provided before.

We can create different implementations of this interface that create different invoices.

If we need to get a buffer, instead of a file, to upload it to a service, for example, S3, we can use

buffer, err := doc.CreateAndBuffer(SimpleA4Invoice{})

where buffer is a *bytes.Buffer pointer.

Documentation

Overview

Package pdfinvoice is a library for generating PDF invoices.

Defining the required environment variables

The following environment variables are required: 

`FONT_PATH` - the path to the font files to be used
`LOGO_FILE_PATH` - the path to the logo file to be used.

In the default options struct, we are expecting the following font files: 

`FONT_PATH`/Roboto-Regular.ttf
`FONT_PATH`/Roboto-Bold.ttf

Creating the document 

doc, err := NewInvoice(nil)

By passing nil as the first argument, the default configuration will be used.

Filling the document with the required information

  • Issuer
  • Customer
  • Type
  • Number
  • Date
  • Series
  • Mark
  • PaymentMethod
  • Notes
  • QrCodeString

Adding invoice entries

Using the doc.InvoiceDetails.AddEntry method, you can add invoice entries. Those are the items sold or services provided.

Calculate Totals and Taxes

  • call doc.CalculateTotals() to calculate the totals

and fill all Taxes entries 

doc.Taxes.WithHoldingTaxes =
doc.Taxes.Deductions =
doc.Taxes.StampDuty =
doc.Taxes.Fees =
doc.Taxes.OtherTaxes =

Generate the PDF

After providing all the required data we need to create the actual document. Each document has a header, a middle body and a footer. Three corresponding functions are responsible to place on the pdf document the data provided before. We need to provide any struct or data type, that implements the InvoiceCreator interface, which provides those three functions.

We have already one implementation of this interface, the simpleA4Invoice.

We create the document with the following code: 

err := doc.CreateAndSave("test.pdf", SimpleA4Invoice{})
