PAYE, RTI and CIS
Nearly 10,000 companies and their agents file PAYE/RTI and CIS with it, and HMRC has recognised it since 2004. Full Payment Submissions, Employer Payment Summaries, CIS300 monthly returns, and subcontractor verifications go from your Windows desktop straight to HMRC, so nobody has to log into the Government Gateway by hand every time.
Licensed per company, with a quote on request.
Making Tax Digital for VAT
The digital link Making Tax Digital asks for, at a price that stays flat as you add companies. Submit a VAT return from the Excel, PDF, CSV, or XML file you already prepared, for up to ten companies, at £25 a month or £300 a year, confirmed on the invoice.
£25 / month or £300 / year, up to 10 companies.
Filing products for accountants and payroll teams, and bespoke systems for the jobs a package cannot reach.
HMRC consults us on how its online tax services are delivered, which is a useful place to be when the schema changes. Gateway Solver is licensed annually and kept current for every change.
Originally incorporated in 2003. On the Isle of Man since 2014 as company 135356C, and filing for UK customers throughout.
Alongside the products, we take a written brief for on-premises AI and workflow automation, design, and support. Selected systems work is on the portfolio.
Healthcare, insurance, warehousing, and aviation, drawn from past engagements. Each write-up says what we built and who we built it for.
Hardware Interface
One office view of policies, renewals, quotes and claims, with barcodes and station scans so sales, underwriting and the mail room worked from the same queue.
Hardware Interface · Mobile
Price check, replenishment, goods receipt and on-device label printing on Windows CE 4.0, with a sync that never assumed the warehouse was online.
Mission Critical
The existing flight-performance tool moved onto the new aircraft type in three days, with an importer so the customer could load aerodrome data themselves from then on.

A control panel that drove Clarity graphics for Sky Quiz Live, so the operator could pick a game and the callers saw it immediately.
The industries we have worked in over the years, which is a fair guide to the kind of brief we can take.
City and county councils, the NHS, police IT, and the Ministry of Defence.
International banks, stockbrokers, corporate service providers, payroll companies, and accountants.
Housebuilders, engineering, and plant hire, including CIS filing for the construction industry.
A live Sky quiz-show control panel, and software for small and medium businesses.
Some of that work could not be allowed to fail: a Ministry of Defence fire-control prototype, NHS blood tracking, diabetic retinopathy screening over HL7, a GP referral system, and real-time trading information for stockbrokers. The same habits go into a payroll bureau's month-end.
Organisations we have worked with over the years, shown from the company files as a record of that work.
In their own words, collected over the years the products have been filing.
