Short answer
Yes — they fund different things, so they stack as long as you don't claim the same cost twice. PSG funds the off-the-shelf tool, EDG funds the custom build or consultancy, and CTC funds the wider transformation around them, up to 70% across equipment, software, consultancy and training. The discipline is clean scope separation: every dollar is claimed under exactly one grant.
Key facts
- Stacking is allowed; double-claiming the same line item is not
- PSG = tools, EDG = custom/consultancy, CTC = workforce + training
- Each cost line maps to exactly one grant
- Sequencing matters as much as the maths
The rule that keeps you safe is one-cost-one-grant. The chatbot licence goes under PSG; the custom integration goes under EDG; the staff reskilling goes under CTC. Overlap a single invoice across two and you create an audit problem.
I've worked a line-by-line stacked example that lands around a 57% effective subsidy on a S$200k programme. The number is real but it depends on disciplined scoping — which is exactly where advisory work earns its keep.
