Invoice and quotes works in the same way. Open the invoice or quote menu and tap "+" in the app. If you don't have the customer tap on "+", otherwise select the customer.
-You can create an invoice by just writing a text and tapping on "Payable amount" to set the price.
-Add items to the invoice by tapping "Add item" or "+". If you need to create a new item tap on "+" once the item list is open.
-You can add a text on the invoice to explain what was delivered. This information can be a maximum of 6 lines if you are using items on your invoice, otherwise it doesn't have a maximum length.
-Tap on the date information to adjust the invoice date or due date,
-Change the configuration of the VAT for the invoice (tap on the amount to do this in the app),
-If you set the price by tapping on "Payable amount" you have set a fixed price (if you want to override the sum of your invoiced items or aren't using any items)
-If you want to credit an item you state the sales quantity with a minus in front "-".
-Add an image or an attachment (you can only add an attachment by logging in at www.speedinvoice2.net).
-Add items by clicking on "+" in the web service or by tapping "Add item" in the app. When adding an item you can write a longer text to clarify services or products delivered for each item.
Functions will be available to you on the screen as icons, or in the menu in the app. When you create an invoice you have a list of features:
-Preview (click on the print icon in the web service),
-Print,
-Email,
-Copy (you can change the customer, items and the pricing),
-Delete (many times it is better to change the customer, items etc. on your invoice as you will get an incomplete number series if you delete it),
If you are working from a phone or a tablet you can also choose to "Share". This will allow you to send the invoice or quote from your mail client, or another app such as WhatsApp or Messenger. This will reduce the risk of being caught in your customers spam filter, if you have communicated with them previously. You can also let your customers sign on your phone and add "Notes" (add a note to the document and set a reminder in your calendar).
Please try making a few invoices to get a feel for how SpeedInvoice works, then delete those invoices. You can change the invoice numbers at www.speedinvoice2.net under "Settings".
