Progress claim software Singapore: what contractors actually need

Progress claims are not just invoices with a different title. For Singapore construction, renovation, and interior design firms, they sit inside a project workflow: milestone completion, retention, certification dates, GST, and the uncomfortable chase for payment.

Good progress claim software should support that whole loop.

What a progress claim should track

At minimum, each claim needs:

• Project and client context
• Claim number or milestone reference
• Certification date, if your contract uses one
• Line items and quantities
• Retention sum handling
• GST rate at the time of issue
• Payment status and due date

The important detail is the snapshot. GST rates, payment terms, and even document templates can change later. A claim issued today should keep the terms that applied today.

Why spreadsheets break down

Spreadsheets work until the team grows or the project drags across multiple claims. Then the problems start:

• Claim totals drift after manual edits
• Retention is forgotten or calculated inconsistently
• The project manager and finance person work from different versions
• Paid and overdue claims are tracked outside the document itself

That creates avoidable disputes. It also slows cash collection because nobody has a single, trusted list of what has been claimed and what remains unpaid.

What Zeng Book is built around

Zeng Book keeps projects, clients, quotations, invoices, documents, and payment status together. For firms that use progress claims, the workflow is designed around milestone billing and retention sums instead of treating every invoice as a one-off PDF.

Start with a quote, convert accepted work into invoices, track payment, and keep the project record intact for the next claim.
