The best CRM depends on how work is sold, delivered and renewed. Compare these four operating models before comparing software brands.
SaaS
SaaS teams often need lifecycle visibility from acquisition to trial, activation, expansion and renewal. Prioritise product and marketing data only when it improves a commercial decision.
Agencies
Agencies need pipeline visibility alongside proposals, capacity and client context. Keep delivery workflow connected without turning the CRM into an unowned project-management system.
Consultancies
Consultancies benefit from clear relationship history, referral source, opportunity shape and next action. Simple discipline often matters more than advanced automation.
Professional services
Longer buying cycles require stakeholders, stages, risk and expected value to remain visible. Choose a system the team can maintain between conversations.
The selection test
Use one representative deal and ask each vendor to show how source, stakeholders, proposal, next action and outcome are recorded.
