Software for trades and contractors
Price the job on site, get it signed, prove it was done, and invoice it with the right CIS deduction — without an evening of paperwork.
For a UK trade or contracting business, the paperwork problem is the same every week: quotes written up at 9pm, jobs signed off on scraps of paper, and CIS deductions worked out by hand. SmartFlo runs that chain from the phone in your pocket — priced quote on site, deposit taken, job signed off with photos, invoice raised with the correct CIS deduction and pushed into Xero or QuickBooks.
A working day, joined up
- 7am — the lead lands. An enquiry from your website or a WhatsApp button is logged automatically with the customer's details.
- 9am — you price it on site. Speak the job into your phone; a branded, priced proposal is emailed before you leave.
- Same day — they sign and pay. The customer signs on their phone and pays a deposit by card.
- On the job — it is signed off. Photos, notes and the customer's signature captured on your phone, even with no signal.
- That evening — it is invoiced. The signed quote becomes an invoice with the right CIS deduction, ready for your books.
CIS done properly
Under the Construction Industry Scheme the contractor deducts tax from a subcontractor's labour — not materials or plant — at 20% if registered, 30% if not, or 0% with gross payment status, and must issue a written payment and deduction statement within 14 days of the tax month end.
CIS Invoicer does the split and the maths for you, produces the HMRC-compliant document, and there is an installable phone app so a subbie can raise one in the van in under a minute.

Common questions
Is there software for subcontractors that handles CIS?
Yes. CIS Invoicer splits labour, materials and plant, applies the 20%, 30% or gross deduction, and produces an HMRC-compliant invoice or payment and deduction statement. It has a phone app so you can raise one from the van.
Can I quote a job while I am standing in the customer's house?
Yes. Speak or tap the job into your phone and a priced, branded proposal with your terms is emailed to the customer before you leave the driveway.
How do I prove a job was done?
Site Visit & Job Sign Off captures photos, notes and the customer's signature on your phone, works with no signal, and emails a completion certificate when you are back in range.
Do I have to buy everything?
No. Every app works completely on its own. Most trades start with quoting or CIS invoicing and add the rest later.
