Subbielane

About Subbielane

Subbielane is built for UK subcontractors paid under the Construction Industry Scheme, and for the small firms that pay them. It works the numbers a subbie handles every month: an invoice from labour, materials, the deduction rate and the VAT charged, showing the CIS deduction and the amount that will reach the bank. A second worksheet works a full year from a day rate, days worked, expenses and the tax already withheld, so profit before tax and the amount still to set aside are clear before the accountant gets involved.

The two worksheets are free and need no account. Subbielane Pro adds a record of every invoice, deduction statement, payment and expense filed against the client and the tax year, with PDF export, reminders and optional connections to Stripe, Xero and QuickBooks Online.

What sets it apart is the focus on one trade niche rather than general bookkeeping. It does not file returns or give tax advice; it simply keeps the figures consistent from invoice to year-end.
