Freelancer invoicing

Invoicing software for freelancers who would rather be working

Create professional invoices in minutes, send them from 3lanse and see at a glance who has paid and who is overdue. Your logo, bank details, VAT number and payment terms go on every document automatically.

Because invoicing sits alongside your clients, projects, days worked and mileage, the numbers are already there when it is time to bill.

Built around your work

From days worked to invoice, without retyping

Log the days you work and the miles you drive against a client and project as you go. When you create an invoice, 3lanse brings in the unbilled days and journeys, so nothing is missed and nothing is billed twice.

Mileage uses the HMRC approved rate by default (45p a mile for the first 10,000 business miles in a tax year), or your own rate if you agree a different one with a client.

Each client keeps its own projects, rates and history, so you can see what a client has been billed this year and what is still owed.

Get paid

Know where every invoice stands

Overdue at a glance

Unpaid and overdue invoices are flagged on your dashboard as soon as they pass their due date.

Mark as paid

Record payments in a tap and keep a clean record for your accountant.

Your branding

Your logo, trading name, bank details and terms on every document, set up once.

Questions

Which plan includes invoicing?

Invoicing, pro formas, credit notes and statements are included in 3lanser Plus (£9 a month) and 3lanser Pro (£19 a month). VAT is added where applicable. You can try them free for 14 days.

Can I add VAT to my invoices?

Yes. If you are VAT registered, add your VAT number and rate and 3lanse calculates VAT on each invoice. If you are not registered, no VAT is added.

Can I send invoices from my phone?

Yes. 3lanse works in any browser and in the 3lanse app, so you can create and send an invoice from site.

Can Aidmin prepare invoices for me?

On 3lanser Pro, ask Aidmin to invoice a client and it prepares the invoice from your logged days and mileage. It sends it only when you confirm.
