Questions Singapore owners ask
Can I use a government grant to pay for this?
Usually not, and we will tell you straight. Most custom automation work is not grant subsidised. The Productivity Solutions Grant (PSG) only funds pre-approved packaged solutions, and a custom build like this is not one of them. The Enterprise Development Grant (EDG) can fit larger qualifying projects, but only with EnterpriseSG approval, and it rarely fits work at this size. From the second half of 2026 these schemes consolidate into a single EDGE grant. If a project does qualify, we will say so and help you apply. If it does not, we will not pretend otherwise.
Will I pay GST on the project?
It depends on the vendor. A vendor that is not GST-registered adds no GST. A GST-registered vendor adds 9%; a GST-registered client claims that back from IRAS, while a non-registered client absorbs it.
How is pricing structured?
A one-time setup fee plus a monthly retainer. The retainer covers ongoing data pulls, template tweaks, and new conditions as the business changes.
