Online invoicing software South Africa

Professional invoicing software for South African small businesses.

Create clear, branded invoices, send PDF copies to customers, record payments and see what is still outstanding from one online workspace.

Practical business tools

Spend less time on admin and keep a clearer business record.

Unit Inc. keeps the document, customer and payment history together. Whether you run a trade, service company, shop or growing team, you can replace disconnected templates and spreadsheets with a repeatable invoicing process.

Professional VAT invoices

Create itemised invoices with quantities, discounts, VAT and clear totals using your own business details.

Send polished PDF invoices

Generate a branded PDF and email it to the customer from the same invoice record.

Track payments and balances

Record full or partial payments and keep the remaining balance visible to your team.

Move from quotation to invoice without retyping

When a customer accepts a quotation, Unit Inc. can carry the customer, line items and totals into an invoice. That reduces duplicated work and helps the final invoice match what was approved.

Each invoice keeps its reference, issue date, due date and source quotation together so you can follow the document history later.

  • Convert accepted quotations into invoices
  • Keep customer contact and billing details together
  • Use consistent invoice numbering and document dates

Know what was paid and what is still due

Record payments against the correct invoice instead of maintaining a separate payment spreadsheet. Unit Inc. calculates the balance from the invoice total and recorded payment history.

Download payment receipts and customer statements when you need a clear record for the customer or your own administration.

  • Record partial and full payments
  • See invoice status and outstanding balances
  • Create downloadable receipts and customer statements

Designed for everyday small-business admin

Unit Inc. works in a web browser and can be installed as a progressive web app on supported devices. Your team can use the same workspace without passing spreadsheets between devices.

Role-based access helps the business owner decide which team members may view, create or manage invoices and payments.

  • Use Unit Inc. on desktop and mobile browsers
  • Keep a shared business record for authorised users
  • Control access based on staff responsibilities
