Buyer Decision Checklist

Most off-the-shelf CRM guidance is written for US or UK buyers — priced in USD, with support hours and integrations that ignore Singapore's accounting, payment, and PDPA realities. Use this checklist to evaluate a CRM platform or implementation partner on the things that actually determine whether the rollout succeeds here.

How to evaluate a CRM platform or implementation partner in Singapore

  • Map your actual deal flow first — how leads enter, who touches them, what triggers each stage change — and buy against that workflow fit, not against a feature list, since over-configuration is what sinks most SME rollouts.
  • Project per-seat licensing to your 24-month headcount and confirm which features sit at each tier, so you are not forced up a pricing band to unlock one capability you need on day one.
  • Pin down implementation scope and data migration in writing: who cleans and maps the legacy data, who owns the cutover, and demand a phased plan with a working v1 in roughly 30 days and harder integrations delivered in waves.
  • Confirm PDPA fit before storing a single contact — that the platform supports consent capture and withdrawal, data-retention and deletion rules, and that your appointed DPO can fulfil access and correction requests; check whether customer data is hosted in or replicated outside Singapore.
  • Test integration depth against your real stack — accounting (Xero, AutoCount, QuickBooks Online), email and calendar (Gmail, Outlook 365), and WhatsApp Business via a BSP — because gaps here force the double-entry that kills adoption.
  • Check whether qualifying costs are claimable under the PSG (approved-vendor list maintained by IMDA / Enterprise Singapore) or EDG for larger transformation projects, and weigh customisation against lock-in by asking how cleanly your data and configuration export if you leave.

Verify for Sellstream

  • Confirm key details directly with the vendor — this listing isn't vendor-managed yet.
  • Ask for two recent Singapore client references you can speak with.
  • Ask for a written scope of services before comparing quotes.
  • Request evidence of relevant certifications and their current validity.

Questions to ask

  • What is included in the implementation scope and what is explicitly excluded — specifically data migration, cleansing, integrations, and post-go-live support?
  • Where is our customer data hosted, and how does the platform support PDPA consent, retention limits, deletion, and data-subject access requests?
  • Can you share two Singapore SME clients in my sector and size who will take a short reference call?
  • If we leave, how do we export our full data and configuration, and what is locked into proprietary objects or custom code?
