The object at the centre of the product
Contacts, tags and journeys on one side; deals, stages and activities on the other. Compare the two designs against the meeting you actually run each week. A campaign performance review is well served by the first. A pipeline review, where the questions are which deals have gone quiet and who owes a buyer a reply, is served far better by the second, and stitching one into the other rarely ends well for a small team.
Compliance you can evidence
Calling from Singapore carries obligations that generic comparisons skip. Check how consent is recorded on the contact, whether preference flags exist, whether changes leave an audit trail, and how you would produce evidence if a customer asked. Ask how the dialer supports suppressing numbers you must not call and how your screening process against national do-not-call rules fits into the daily workflow rather than sitting beside it in a spreadsheet.
Currency, metering and portability
Compare whether a deal can hold its own currency and still roll into one forecast figure. Compare how the bill is metered, by contact, by seat or by tier, because that shape determines how cost grows. And check that contacts, deals, activities and notes can be exported by you, on demand, in open formats. For a lean team with no internal systems owner, portability is worth more than an extra reporting module.
