What we build
Bespoke software without the bespoke price tag.
Most businesses don't have a data problem, they have a joining-up problem: the same figures live in a spreadsheet, an accounts package, a CRM and an inbox, and someone reconciles them by hand every week. For UK SMEs with 5–100 staff who've outgrown spreadsheets but can't justify £25k+ agencies or ever-growing per-seat SaaS.
Exseed Advisory builds bespoke software for UK SMEs: professional websites from £500, fixed-price platforms from £4,000, or a build-and-subscribe model from £300 a month — with a CISO-led security review before anything goes live.
Typical builds
The systems that quietly run a business
If it currently lives in a shared spreadsheet, an inbox and someone's head, it can usually be built properly.
- Data consolidation across systems
- Transcription and conversation intelligence
- Client portals
- Internal ops tools
- Dashboards and reporting
- CRM and pipeline tooling
- Quoting, booking and workflow apps
- Mobile apps that work alongside the platform
Websites
Just need a website?
Not every business needs a platform. If you need a professional, secure website that actually brings in enquiries — and someone to keep it running — we do that too, from £500. And because we build it properly, it can grow into a client portal or an internal tool later without starting again.
Apps
Apps for the people who aren't at a desk.
Most of the work in an SME doesn't happen in front of a screen. Carers, engineers, drivers and site teams need the same system as the office — in their pocket, working when the signal doesn't.
So when we build a platform, we build the app alongside it: the same data, the same permissions, one record. Where a device is involved, the app gives it context — which job, which customer, which visit — and buffers what it captures until it can sync, so nothing goes missing between the field and the record.

FAQ
Common questions
How much does bespoke software cost for a small business?
- Our indicative pricing is published: a professional website from £500 then from £45 a month; a fixed-price Spark build of one tool, portal or dashboard at £4,000–£9,000 over 2–4 weeks; a larger Platform build then £300–£900 a month for hosting, maintenance, security monitoring and small changes; and a Rescue security audit of an existing AI-built app at £750–£2,500. Every quote is fixed before we start.
Do you only build platforms, or can we just have a website?
- Just a website is fine. A professional, secure site starts at £500 with a monthly fee for hosting, security updates, backups and small content changes, and because it is built properly it can grow into a portal or internal tool later without starting again.
Do you build mobile apps?
- Yes. When we build a platform we build the app alongside it — the same data, the same permissions, one record — for the people who aren't at a desk. Where a device is involved, the app gives it context and buffers what it captures until it can sync.
What if we already have an app someone built with an AI tool?
- Bring it to us for a Rescue audit: a fixed-price review of row-level security, secrets, authentication and headers, with a prioritised fix plan you can act on.
