Sound familiar?

  • Operations

    Jobs come in on WhatsApp and get dispatched from a whiteboard. When a technician is off sick, nobody knows which jobs to move.

  • Admin

    Service reports come back as photos of paper. Invoicing waits until someone types them up.

  • Rental desk

    Equipment comes back late or damaged, and we forget to charge the extra days.

Suggested Phase 1 scope

Start with jobs, reports and equipment.

This scope starts where jobs leak money: requests, dispatch, signed reports and equipment on hire. Reminders for overdue accounts follow once invoicing runs from the reports. It runs on the same AI ERP modules we build for every trade. Treat it as a starting point: we shape the real scope with you on the scoping call, and the written phase plan states it.

Ask your records

Questions your team asks every week, answered from the records.

Each answer names the record it came from. The records belong to Cobaltline Services, a fictional aircon servicing and equipment hire company.

Who can take the Jurong West aircon job tomorrow morning?

Team B. They finish in Boon Lay at 8:45am, about 15 minutes away, and their van has the R32 gas the job needs. Team D is free too, but starts from the depot.

Dispatch board, 8 Nov · Van stock VAN-B

Where a person decides

By default, agents draft and a person approves.

  • Suggest

    The agent recommends. A person does the work.

  • Draft for approvalDefault

    The agent prepares the record and waits. Nothing changes until a person approves. This is the default.

  • Act within limits

    Opt in per action, under a S$ limit you set. Payments, deletions and messages to customers or suppliers always stop at a person.

Singapore context

What we design around here.

General context, not legal or tax advice. Your phase plan says which of these your first phase covers.

Maintenance contracts

Aircon, lift, fire safety and M&E maintenance often run on contracts with set visit schedules. Contract visits are created as jobs ahead of time, so they are on the board before they are due.

Site access

Condos, offices and industrial sites often need access booked with the management office. Each job can hold the access window, the site contact and any permit reference.

GST on jobs and hire

Service invoices and hire charges show GST at the current 9% rate, and supplier bills keep the GST you paid.

Modules and agents used

The modules and agents behind it.

The first phase and the later ones draw on the same modules and agents we build for every industry. Each one has its own page.

FAQ

Field service questions

Can technicians use their phones on site?

+
Yes. Jobs, photos, parts used and the customer's signature are captured in the browser on a phone, and the signed report goes to the office for invoicing.

Can it run maintenance contracts with scheduled visits?

+
Yes. A contract holds the sites, the units and the visit schedule, and visits are created as jobs ahead of time for your operations team to assign.

How is equipment on hire tracked?

+
Each item has a hire record with on-hire and off-hire dates, the daily rate, the deposit and condition photos at both ends. Late returns and damage are drafted as extra charges for a person to approve.

Jobs come in on WhatsApp. Can the agent read them?

+
Not as standard. The document intake agent reads emails, PDFs and photos sent to the inbox or upload page you choose, so staff can forward a WhatsApp message there. Reading WhatsApp directly can be added on request, and we scope it with you.

Does an agent dispatch technicians?

+
No. By default, agents draft and a person approves. The system shows who is free and nearby, and your operations team assigns the job.

How long does a first phase take, and what does it cost?

+
A Quick build covers one workflow: from S$15k, with 2 to 3 days of build. A Build covers a set of modules and agents: S$30k to S$40k, with 4 to 5 days of build. Scoping, testing with your team and moving your data add calendar time, and the phase plan sets out the dates. There are no per-user licence fees. See pricing.

Who owns the system when it is built?

+
You do. You own the full source code of what we build, with no per-user licence fees, and it can run on our hosting or in your own cloud account. SleekDigital keeps its internal build engine and tooling. How we work.

Can we see it working before we commit?

+
Yes. On the scoping call we show the approval queue and the records on sample data from your industry, like the examples on this page. We don't publish client work without the client's permission.

Can we use the EDGE grant?

+
Possibly. Enterprise Singapore's EDGE Grant replaced EDG, PSG and MRA from 30 Sep 2026, and support depends on its assessment. You must apply before any work starts or any payment is made. We can't promise a grant outcome or percentage for your project. How EDGE works.
