UK Software Consultancy. Since 2018.

Custom software for mortgage brokers, surveyors and property firms.

From client portals to full application engines, we design and build software for UK firms that have outgrown spreadsheets. Real systems, built by people who understand how your business runs.

What we build

Client portals, CRMs, application engines, dashboards, broker tools, websites. If your firm runs on spreadsheets and email chains, we replace it with software that actually works for your team.

02

How we work

We start with what slows your team down. Then we design, build and ship in weeks, not quarters. Fixed scope, fixed timeline, fixed price. No surprises along the way.

03

Who we work with

Mortgage brokers, surveyors, solicitors, estate agents and property firms across the UK. We understand your world. You won't be explaining what a party wall award is.

About AppMarketStore

Software built around your business, not the other way around.

AppMarketStore has been building software since 2018. We work with growing UK firms in the property, mortgage and professional services space who need software that fits the way they actually work, not the way an off-the-shelf tool wants them to.

From single-page broker portals to full multi-user platforms with document handling, application tracking and client logins, we design and build it all in-house. You get a real engineering partner, not an outsourced team you'll never meet.

Why AppMarketStore

Four reasons firms pick us over the big agencies.

01

We know your industry

We've built for mortgage brokers, surveyors, solicitors and property firms. We speak your language and understand the regulations, the workflows and the buyers.

02

Fixed price, fixed timeline

No hourly billing. No scope creep. You know exactly what you're paying and when it ships before we write a line of code.

03

You own everything

The code, the database, the design. All yours. No lock-in, no per-user fees forever, no licence held over your head.

04

Built to last

We use the same modern stack the best startups use. Your software will still be running smoothly five years from now without rewrites.

Featured project

Party Wall Guru

We built Party Wall Guru to help homeowners and surveyors connect, manage party wall notices, and handle the back and forth that usually clogs up email inboxes for weeks. The platform now serves surveyors across the UK and turns what used to be a paperwork-heavy process into something you can actually finish in an afternoon.

  • Homeowner enquiry and matching flow
  • Surveyor profiles and lead routing
  • Notice generation and document handling
  • Built for UK party wall regulations
