The D&B Operating System is interior design and project software for UK design-and-build firms, fit-out contractors, kitchen and wardrobe companies and joinery businesses. One system covers enquiries, surveys, design rounds, quotations, agreements, projects, site updates, team roles and stage payments.

How UK interiors and joinery businesses work
The UK market splits into two worlds. Commercial fit-out, strongest in London and the big regional cities, runs on Cat A and Cat B work for landlords and tenants, usually under JCT-style contracts with main contractors and specialist subcontractors. Residential work covers refurbishments, extensions, kitchens, bathrooms and fitted furniture for homeowners.
Bespoke joinery workshops sit across both, making kitchens, wardrobes, staircases and shopfitting. They juggle surveys, drawings, client sign-off, workshop time and installation slots. Subcontractors in construction also deal with the Construction Industry Scheme (CIS) for tax deductions, and VAT-registered firms need proper VAT invoices.
Problems it solves for UK teams
- Enquiries from Houzz-style directories, Instagram, Google and word of mouth, tracked in someone's inbox.
- Quotes written in Word or Excel, with no link between the approved price and the invoice.
- Design sign-off buried in email threads, so disputes over what was agreed are hard to settle.
- Fitters and site leads reporting progress by text, with photos stuck on their phones.
- Deposits and stage payments that depend on someone remembering to invoice.

Your brand on every screen
The system runs on your own domain with your logo and colours, and your firm keeps full admin control of users, roles and data.
Onboarding from India, with a UK-friendly overlap
BRANDSWOT Consultancy has no UK office. Setup is remote: a demo by video call, a written quote, then deployment on your domain with your branding, stages, roles and rate cards. India is several hours ahead of the UK, so UK mornings overlap with the Indian working afternoon.
Plans and early access
Studio covers firms of up to 10 people, Practice covers 10 to 30, and Enterprise covers larger firms or several offices with custom workflows, priority support and training. Pricing is on request. The product is in early access, with a small number of firms onboarded at a time.

Beyond London, firms in Manchester, Birmingham and Leicester run a mix of residential refurbishment, kitchens, shopfitting and commercial fit-out. They may search for interior design software, an interior design CRM or design and build software. The underlying need is the same: one record from enquiry to final payment.

Interior contractor software users also get interior design quotation software built from rate cards. Fitters use the site progress app from a phone browser.
Small teams can use it as a construction project management app for small contractors, on the Studio plan for up to 10 people. Setup is remote from India. BRANDSWOT Consultancy has no office in Manchester, Birmingham or Leicester.
More questions
Can a joinery workshop in Birmingham or Manchester use the D&B Operating System?
Yes, for the job side of the work. Each job moves from enquiry and survey to a quote from your rate cards, client sign-off, tasks, installation updates and stage invoices. Workshop tools such as cutting lists and machine scheduling stay separate. Invoicing was designed around Indian GST, so confirm UK VAT needs with us before you commit.
Questions people ask
What is the best interior design software in the UK?
No single product suits every UK firm. Compare tools on enquiry tracking, quotations, client sign-off, change control, site updates from a phone, stage billing, roles and branding, and check VAT and data-protection needs.

Is there joinery project management software for UK workshops?
The D&B Operating System handles the job side of joinery: enquiry, survey, quotation from rate cards, agreement, tasks, installation updates and stage invoices. It has no dedicated cutting-list or machine-scheduling module. Tell us your workshop requirement and we'll confirm what's supported. Many workshops keep their production tools and use the D&B Operating System for enquiries, quotes, client sign-off and stage payments.
Looking for a kitchen and wardrobe CRM in the UK?
Look for a CRM that logs lead sources, sets follow-up reminders, links each lead to a survey and quote, and follows the job through to installation and final payment. The D&B Operating System does this in one record. Also check how a tool handles deposits, stage payments and your branding before choosing.
Is there fit-out project management software for London contractors?
Yes. The D&B Operating System puts each fit-out on a timeline from design to handover with task owners, delay alerts, vendor status, supervisor photo updates and a snag list. Owners see late projects, money due and team workload in one dashboard. Site leads post progress from a phone browser, so the office sees updates without waiting for an end-of-day call.
Does it support UK VAT and CIS?
We don't claim UK VAT, CIS or Making Tax Digital compliance. The invoicing module was designed around Indian GST. Tell us your requirement and we'll confirm what's supported. Many firms keep their accounting software for tax and use the D&B Operating System for leads, projects and payment tracking.
Does it have an interior design client portal?
Clients can approve quote versions, and their design comments sit in one thread, all under your brand. For any other client-portal feature, tell us what you need and we'll confirm what's supported. Keeping approvals on the project record also makes it far easier to settle any later disagreement about what was signed off and when.
