A useful demonstration
Evaluate a representative mix of cases
If your firm handles more than straightforward residential mortgages, include that variety in the demonstration. Choose fictional cases that reflect your actual work and ask who owns each next action, what information is required and which tools handle the specialist steps. Compare the number and purpose of handovers rather than counting screens.
For firms working with introducers, other brokers or a network, draw the boundaries of access first. Ask each provider to demonstrate what each person can see and change using the proposed configuration. Include the case where a document arrives late or a different adviser takes over. A workflow should remain understandable when responsibility changes.
Before a move from OMS, list the provider connections and business rules currently used. Separate essential launch requirements from improvements that can wait. Agree how ongoing cases will finish, how documents will remain accessible and how you will validate the new records. Compare migration and onboarding scope alongside price, using the same written requirements for both providers.
Where Achos needs a closer fit check
Specialist mortgage sourcing, identity/AML, e-signature and Open Banking connections are planned. There is no promised provider or launch date. Google and Microsoft profiles support email sending with setup; that does not promise full mailbox or calendar synchronisation. Check your current dependencies against the integrations and availability page.
Achos does not guarantee time savings, regulatory compliance or migration coverage. Confirm required capabilities, permissions, support and commercial terms for your organisation. A controlled pilot with your team is the best next step before committing to a change.
Make the decision concrete
Three checks before you choose.
Try the work, with the people who do it
Use a fictional but realistic case from enquiry through to completion. Include an adviser, an administrator and a reviewer. Ask each person to find the next action, request a document and explain the case history. Record any extra tools or repeated data entry rather than relying on a demonstration of the easiest path.
Agree the complete cost
Request written terms covering the recurring charge, user or case limits, minimum term, configuration, training, migration and third-party services. Model the cost at your own case volume. A cheaper headline price can still describe a different scope; compare the services your team will actually use.
Validate a small migration before rollout
Agree the source export, field mapping and document handling. Test open and completed cases, check client relationships and notes, and decide how historical records will remain available. Give the team time to verify the pilot and agree the cutover steps before relying on the new workspace for live work.
Questions about Achos and OMS
What does OMS stand for in this comparison?
OMS refers to One Mortgage System, the UK mortgage CRM provider at onemortgage.co.uk. The comparison focuses on broker case operations and the published platform offering, rather than unrelated products with the same initials.
Can Achos replace all of our OMS integrations?
No such replacement is promised. Achos specialist sourcing, identity/AML, e-signature and Open Banking connections are planned. List every integration your team uses and confirm how the work would be completed before considering a switch.
What should a specialist broker test in a demo?
Use a representative case and demonstrate its required information, stages, documents and permissions. Include handovers between the people and firms involved. Confirm any provider dependency and test what happens when information changes or a case cannot follow the standard route.
