What it does
Everything CIS. Nothing you don't need.
CIS isn't an afterthought bolted onto payroll software here. It's the whole product, so every screen is about getting subcontractors paid correctly and your returns filed on time.
Subcontractor verification
Share details and verify subcontractors with HMRC through a simple wizard, singly or in bulk.
Monthly returns
CIS300 returns built from the month's payments and submitted to HMRC for you.
Payment & deduction statements
Statements generated and emailed to every subcontractor automatically each month.
Payments
Record payments to subcontractors and export payment files for your bank's BACS system.
Remittance advice
A PDF of payments and CIS deductions for any date range, emailed straight from the app.
VAT & Domestic Reverse Charge
VAT registration and default rates per subcontractor, with DRC applied to invoices when it's due.
CSV imports
Bring in subcontractors and weekly or monthly timesheets from a spreadsheet, validated row by row.
API-first
Everything the app can do, the API can do too, so your own systems can work with CIS Manager.

From the month's payments to a filed CIS300.
Every payment you record works out its own deduction from the subcontractor's verification status. At month end the return is already built: check it, submit it, and statements go out automatically.

From people using CIS Manager

“I have just found the automatic emailing function of statements this is soooo good. I should not be getting so giddy over a software package but so far, I am pretty happy.”

“I found a list of HMRC recognised programs. I tried a couple but they were more complicated than what I wanted. Then I came across your program which was perfect for me.”
