Sound familiar?

  • Quantity surveyor

    Progress claims eat days every month. The numbers live in five spreadsheets and the site photos are on someone's phone.

  • Project manager

    Variations get agreed on site and priced weeks later. By then half of them get argued down or forgotten.

  • Finance

    Subcontractors chase us for payment, and we can't see what we've certified against what we've paid.

Suggested Phase 1 scope

Start with projects and progress claims.

This scope starts where the money is: the BOQ, site progress, variations and the monthly claim. Purchasing and subcontractor invoices follow once projects are set up. 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 Bukit Ardent Construction, a fictional main contractor.

What can we claim on P-114 for October?

S$186,400.00 of work: S$171,900.00 from the BOQ at the progress the site reported, plus S$14,500.00 for approved variation VO-06. Less 5% retention (S$9,320.00), the claim is S$177,080.00 before GST.

BOQ P-114 rev 3 · Site report 31 Oct · VO-06

Which variations on P-114 were agreed on site but not priced yet?

Two. VO-08, move the drainage sump (site instruction SI-031, 24 Oct, with photos). VO-09, extra cable tray on level 2 (SI-034, 30 Oct). Neither is in a claim yet. Both are drafted for the QS to price.

Site instructions SI-031, SI-034

What do we owe Lumen Wiring Works, and what have we certified?

Certified to date S$96,000.00, paid S$78,000.00, so S$18,000.00 is certified and unpaid. Their latest invoice asks for S$21,500.00, which is S$3,500.00 more than certified, so the AP invoice agent has held it for review.

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.

Security of Payment Act

The Building and Construction Industry Security of Payment Act gives anyone who does construction work, or supplies goods or services, under a written contract the right to claim progress payments. The other party replies with a payment response, and disputes can go to adjudication. Each project can hold its claim and response dates so they are easy to track. Your contract and the Act set those dates.

Last checked 7 Nov 2026

GST on claims and invoices

Progress claims, variations and subcontractor invoices carry GST at the current 9% rate where the business is GST-registered, so what you charge and what you can claim back sit in the same records.

Retention and back charges

Retention held and released, back charges, and amounts certified but unpaid are kept per subcontract, so finance can see what each subcontractor is owed at any point.

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

Construction questions

Does it follow the Security of Payment Act?

+
Each project keeps its payment claims, payment responses and the dates your contract sets, so the QS and finance can see what is due and when. The Act and your contract set the rules. We build the records around them, and your contracts adviser should confirm the dates. BCA: Security of Payment Act (opens in a new tab).

Can the site team use it from a phone?

+
Yes. Progress, photos and site instructions are logged in the browser on a phone. The document intake agent turns photos of delivery orders and site instructions into draft records for someone in the office to check.

We price from a BOQ in Excel. Do we retype it?

+
No. Your BOQ comes in as the project's starting budget when we move your data, and the progress claim agent measures work done against it.

How do variations stop slipping through?

+
Each variation is its own record: the site instruction, photos, price, the client's approval and the claim it went into. Anything agreed on site but not yet priced stays on a list until someone prices it.

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.
