The Contractor's Weekly Crisis

The SGD 4,500 Misunderstanding You Have Every Single Project

A standard client conversation on final billing handover week that drains your net earnings.

If it is not signed, it doesn't exist.

Verbal agreements lead to unpaid final bills, ruined client relationships, and CASE / Small Claims Tribunal disputes. Homeowners forget easily, or assume small on-site scope changes are complementary additions. Keep your scope locked.

Sounds familiar?

Verbally agreeing with a client on a crowded site leads to lost materials, unpaid labour, and tedious back-and-forth arguments. By the time final handovers come, hundreds of dollars (or even thousands) are lost.

With VOLock SG, site designers can log any extra request directly onto their mobile phone while talking to the client. Send an automated request in 1 tap, and get homeowner verification instantly before materials are ever ordered.

SGD 1,500+Avg Loss / Project

Leaked per interior designer in SG due to undocumented work disputes.
