Before creating sales invoices, quotes, or credit notes in Dext Solo, you need to complete a one-time setup. This adds the business details, payment information, and document numbering that appear on all documents you create.
You can start the setup from Business settings > Sales invoices > Complete set up, or you'll be prompted to complete it the first time you try to create any sales document.
Note: Sales invoicing is only available for Dext Solo clients.
Complete the setup
The setup runs through four steps. You can select Skip setup at any point to complete it later, but the setup must be finished before any document can be finalised.
Step 1 - Business details
Enter the business name. This appears on all invoices, quotes, and credit notes issued to customers.
Step 2 - Business address
Enter the business address. This is required on customer-facing documents.
Step 3 - Payment details
Enter the bank details and payment terms that will appear on invoices:
Bank name, Account number, Sort code
Default due date - sets the default number of days after the invoice date that payment is due
Payment terms - free-text field for payment terms shown on the document
Notes - any standard notes to include on all documents
Select Continue when ready.
Step 4 - Numbering
Set the prefix and starting number for invoices, quotes, and credit notes. Dext previews the first document number for each type as you type.
Note: Number sequencing can't be edited after you finalise your first document. The prefix can be changed at any time.
Select Save to complete the setup.
Complete the setup on mobile
The setup is also available in the Dext mobile app. You'll be prompted to complete it the first time you select Create a sales invoice from the camera menu, or go to Quotes in the bottom navigation bar and select Create.
The mobile setup follows the same four steps - Business details, Business address, Payment details, and Invoice numbering. Select Complete on the final step to finish setup.
You can update the business logo at any time from the More tab in the bottom navigation bar. Logos must be JPEG or PNG format, maximum 1 MB, and at least 480 x 240 pixels. The logo size on documents can't be adjusted after upload.
Edit settings after setup
Once setup is complete in the web or mobile app, all settings are editable from Business settings > Sales invoices in the Dext web app.
The page is divided into sections:
Sales invoice details - edit the business name, registered address, and logo. The logo is managed via Business profile. See How to add your company logo in Dext for instructions.
Payment details - edit bank name, account number, sort code, default due date, and payment terms.
Document numbering - view current sequences for invoices, credit notes, and quotes, showing the next number and last issued number for each. Select Create sequence to start a new numbering sequence, or View previous sequences to see earlier ones.
Note: Once a prefix has been used, its number is locked and continues sequentially.
Document defaults - set a default category to apply to all new sales invoices.
Customization - three options:
Display 4 decimal places: shows prices to 4 decimal places on documents instead of 2
Strapline: toggles the "generated by Dext" line on documents
Notes: sets a default notes field that appears on all documents, which can be overridden when creating individual documents
Lock invoice date - toggle Limit new invoices to current date to lock the invoice date to the date of finalisation, making it uneditable after that point.
Set up customer details
Customer billing details are required to finalise a sales invoice. You can manage customers from Sales > Customers.
To add a new customer, select Add new customer. To edit an existing customer's details, select their name from the list and go to the Invoicing details tab, then select Change.
Enter the customer's company name, email address, payment terms, notes, billing address, and shipping address. The billing address is required.
Note: A customer's billing address must be completed before a sales invoice addressed to them can be finalised.
Set up products and services
If the client sells recurring products or services, adding them to the products and services list lets them be selected quickly when creating invoices and quotes, rather than being entered manually each time.
To manage products and services, go to Sales > Products and services.
To add a single product or service, select Add product/service and fill in the SKU, name, type, description, unit price, and sales account, then select Add.
To add multiple products or services at once, select Import from CSV. Your CSV must include a header row with the column names. The required format is Name, SKU, Description, Unit price (excl. VAT), and Type. After uploading, map your CSV columns to the correct fields and select Submit.
The Visible toggle on each item controls whether it appears as an option when adding line items to a document. Toggle it off to hide items you no longer use without deleting them.
