costin by site software

Switching to costin. We do the typing.

Whether you're on spreadsheets, paper, an old database or another app, send us what you have and we'll bring it in for you, free. You don't start from an empty screen.

How it works

  1. Start your free trial

    Or take the tour first, and email us any questions.

  2. Send us what you've got

    Spreadsheets, a list of customers, your price list, an export from your old system — whatever shape it's in.

  3. We bring it in

    Customers, suppliers, subcontractors and your materials and price list, set up in your own copy of costin.

  4. We set the basics up

    Your letterhead, VAT and CIS details, from what you send. costin’s help pages walk you through connecting Xero or QuickBooks, and we’re on email if you get stuck.

  5. Start with your next job

    Run new work in costin from day one and let older jobs finish where they are, if that's easier.

Useful to send us

  • Customers, with addresses
  • Suppliers and the accounts you hold with them
  • Subcontractors, with their UTR and CIS status
  • Your materials or price list
  • Your logo and invoice details
  • Any jobs that are still running

Not sure what you've got? Send it anyway — we'll tell you what we can use and how long it'll take.

Coming from another app?

Most apps let you export your customers and price list as a spreadsheet. Send it over and we'll do the rest. If you're moving because per-user prices have crept up as your team grew, see what costin costs for your team.

Your accountant stays in the loop

costin connects to Xero and QuickBooks, so invoices, bills and payments carry on landing in your books. You can set a date before which nothing is ever sent, so the history your accountant already has can't be entered twice.

Ready when you are.
