We build bespoke tools and AI automation for UK small & medium businesses — the job management systems, booking platforms, and internal apps that replace the spreadsheets, clipboards and sticky notes your business currently runs on.
Every engagement starts with the Audit — that's how we make sure we're solving the right problem before a line of code gets written.
Two weeks. We map how your business actually runs, find the 3–5 operational bottlenecks costing you the most, and give you a ranked plan.
Job management, booking, client portals, stock, e-commerce, internal tools. Built to your workflow — not a template bent around it.
Software is never finished. We stay on hand for fixes, iterations, new features, and AI workflows that grow with you.
50% credited back on any follow-on build. No retainer lock-in.
Two 90-min calls with you and up to three of your team. We walk every process end-to-end — quoting, scheduling, delivery, billing.
Where hours are lost. Which tools you already pay for. Which integrations are held together with CSV exports.
Honest assessment of where AI genuinely helps — and where it's being oversold. No hype, no invented use cases.
A written, ranked plan — quick wins, 3-month builds, 12-month ambitions. Each item costed in hours reclaimed and £ saved.
For each opportunity: bespoke build, off-the-shelf tool, or leave alone. We'll say when SaaS is the right answer — even though it's not what we sell.
Every project — whether a £2k website or a £40k platform — moves through the same four phases. You'll always know where we are.
Map the operation. Find the real problem — which is rarely the one you were told.
Wireframes, technical spec, fixed quote. You sign off before a line of code is written.
Weekly demos. Real staging environments. Your team tests with real data from day one.
Handover, training, optional monthly retainer. We stay as long as you need, no longer.
We specialise in the sectors SaaS forgot — too small for enterprise, too specific for templates, too operationally complex for a Notion doc.
Joiners, electricians, roofers, plumbers. Quoting, scheduling, certs.
Bookings, client records, treatment plans, stock, recalls.
Small-batch producers. WIP tracking, BOM, dispatch, quality logs.
Shopify/Woo with proper operational backends — not just a storefront.
Private clinics, therapists, physios. GDPR-first patient workflows.
Route planning, POD capture, driver apps, stock reconciliation.
We quote flat fees once the spec is signed off. No day rates hidden in a retainer. No "it depends."
The only way in. Two weeks from brief to roadmap.
Scope-dependent. Brochure builds from £1.5k; full platforms £10k–£50k.
Optional retainer. Hosting, monitoring, fixes, and a pool of dev hours.
Before onSync I was the person a lot of founders phoned at 11pm when the spreadsheet broke. I've built job management systems for builders, stock control for manufacturers, booking platforms for clinics, and dispatch tools for couriers.
The pattern is always the same: the business grew faster than its tools. The operational mess isn't a personal failing — it's what happens when a 3-person workshop becomes a 20-person one and nobody had time to re-plumb the engine mid-flight.
That's the work. Unglamorous, specific, and worth doing properly.
Two weeks, £495, no obligation. At the end you'll have a plan — and a much clearer picture of whether we're the right team to build it. Or not. Either's fine.
