Proposal·Prepared 1 May 2026

AI-led booking automation for Paterson Associates.

Two practical routes for Phase One — one if Cube gives us the access we need, one if it doesn't. Both deliver the same operational outcome: more cases booked, on time, without adding team headcount.

Cube API access to confirm route
01 · Context

What we heard during discovery.

More work is arriving than the current booking process can absorb. Cube sits at the centre of operations, and how it exposes data shapes the right path forward.

Surveyors with rules
The valuable part is deciding what slot to offer.

Surveyor rules, mileage, current bookings and cluster opportunities all need to be checked before the system ever picks up the phone.

Standard bookings consume team time that should sit elsewhere.

Most cases are routine. Automating these frees the team for the complex ones that genuinely need human judgement.

Cube is central — but API access decides the route.

If Cube exposes the data we need cleanly, we integrate. If it doesn't, we build natively. The work itself is the same.

02 · The two routes

One decision, two practical paths.

The operational outcome is identical. The difference is where the booking workflow lives — inside Cube's orbit, or in a focused CRM purpose-built around Paterson's way of working.

What you get with Route B

A purpose-built booking CRM for Phase One, replacing Cube for the booking workflow if Cube cannot give us the access required. Every customer has a single, searchable booking record. Inbound and outbound calls (recorded and transcribed), emails, SMS and messages all sit on the customer timeline. The £38,000 includes the CRM build and agreed active workflow data needed for go-live. Full historical Cube export, cleansing and migration is available as an optional £12,000 + VAT add-on.

Route B · Unified customer record
One timeline per customer. Every interaction, automatically captured.
Inbound & outbound calls

Every call recorded, transcribed and tagged to the customer — voice AI calls and surveyor calls alike.

Email threads

Inbound and outbound email captured against the customer — no more lost replies in personal inboxes.

SMS & messaging apps

Two-way SMS plus messaging-app threads on the same record. Replies route back to the right case automatically.

Searchable history

Filter by customer, surveyor, case stage or keyword. The full back-story is one click away.

AI-aware context

When the AI calls back or follows up, it does so already knowing what was said before — no awkward repeats.

Audit-ready

Timestamped, attributed and exportable. If a case gets challenged, the conversation history is right there.

This unified communications layer is what makes Route B more than just a booking tool — it becomes the operational record for every customer Paterson talks to.
03 · Phase One

The first release: the minimum operational engine, done properly.

Standard inspections booked end-to-end, with joint expert coordination available where the workflow lives inside the Native Booking CRM.

  • Engage AI Voice AI inbound + outbound
  • SMS & email follow-up workflow
  • SLA Day 2 / Day 3 alert routing
  • Notes, transcript summaries & write-back
  • Exception escalation for complex cases
Joint expert coordination

Dependent on everyone working on the same system. This is the only way the AI can manage the complexity; otherwise it still needs to be done manually. Only available on the custom CRM build.

Later phases
  • Solicitor updates
  • Surveyor portal
  • Advanced reporting & dashboards
  • No-access & rebooking automation
  • Wider case lifecycle workflow
  • Additional service lines

Later phases extend the booking foundation into broader case lifecycle workflows, reporting, portals and more advanced exception automation.

04 · Commercial

Fixed Phase One pricing. No ranges, no surprises.

The build price is fixed once the route is confirmed. The managed service is a flat monthly. Provider usage stays separate so you keep direct visibility and control.

Route A · Cube-Integrated4–6 weeks
£24,000
fixed Phase One build · one-off
Best when Cube API supports clean read/write for cases and activity.
Route B · Native CRM6–8 weeks
£38,000
fixed Phase One build · one-off
Best when Cube is the blocker, or when you want booking native. Includes agreed active workflow data for go-live; excludes full historical data cleansing and migration.
Timeline assumption

The 4–6 and 6–8 week timelines assume timely provision of all client dependencies. Delays in providing required materials may extend the delivery timeline proportionally.

Optional add-on · Native CRM only

Historic Cube Data Migration

Export, clean, map and import historic structured Cube case data into the Native Booking CRM. Subject to receiving usable Cube exports. Document/file migration, scanned PDFs, email archives and manual correction of poor-quality records would be scoped separately.

Paterson owns the provider accounts; we set them up and manage them. These figures assume ~100 cases per week and are not part of the managed service fee.

£465
per month, indicative
You own every account

As an FCA-regulated firm and the Data Controller, it is important that you hold all third-party service accounts directly in your name. This means full regulatory compliance with no data processing through intermediary accounts, complete transparency on costs with no markup, and no vendor dependency. If your relationship with Engage AI ever ends, your accounts, your data, and your service relationships remain yours.

Errors & omissions

Pricing reflects the scope as we currently understand it. If something material was missed and only surfaces during the build, we'll flag it openly and agree any adjustment with you before continuing.

05 · Next steps

A clear path forward. No paid discovery.

We review what Cube can do at no charge. You see workflow mockups before committing. Then we issue the fixed Phase One proposal for the confirmed route.

    No paid discovery — shared at no charge.
  2. 02
    Engage AI reviews the API at no charge
    We confirm cleanly what Cube can and cannot support.
  3. 03

In short
If Cube gives us the access we need, we integrate. If Cube becomes the blocker, we build booking natively. Either way, you get a working booking engine in production within weeks.
