Integration that ships.
Integration consulting for finance, CRM & project tools

About marvlus
marvlus designs, ships, and supports integrations for teams that need enterprise reliability without enterprise drag. We scope clearly, build fast, and leave you with clean handover.
- Security-first delivery with least-privilege access and audit trails.
- Observability baked in: logs, alerts, and runbooks you can use.
- Documentation and handover so your team isn't locked to us.
We meet you where you are-API-first builds, iPaaS rollouts, or stabilizing what already exists. Expect clear milestones, regular progress updates, and production-ready integrations that are easy to maintain.
See how we workIntegration work that is built to run
We align with your roadmap, ship in short iterations, and leave observability in place so you can see every connection working. No black boxes - just reliable data flow with clear ownership.
We work to clear, agreed milestones with a prioritised backlog, regular demos, and a decision log. Scope is transparent, so trade-offs are agreed before we build.
Least-privilege access, secret management, and peer-reviewed changes by default. We align to your data handling rules and share audit-friendly change notes.
Runbooks, sequence diagrams, and API notes are delivered with the build. We hand over credentials, alerting, and dashboards so your team stays in control.

- Proven approach refined across a wide range of industries and platforms

Discover & scope
We map systems, owners, and constraints. Risks are logged early, and acceptance criteria are clear before we write code.

Experience
Before founding marvlus, our founder spent over 20 years designing and delivering integrations across finance, project delivery, and sales platforms. Highlights include:
Finance, HR & accounting
Multiple integrations synchronising personnel and financial data between HR, payroll, and finance systems, replacing manual re-keying with validated, auditable data flows.
Project delivery, service & time tracking
Connecting work items, service tickets, and logged time from delivery and service management tools to the systems that plan, cost, and bill the work, so effort and budgets stay in sync.
CRM, sales & collaboration
Integrating customer, opportunity, and account data with delivery, finance, and collaboration platforms, giving one consistent view from first deal to final invoice.
Project portfolio management
Linking PPM platforms with CRM, delivery, and finance tools so project, resource, and financial data flows automatically across the organisation.

Frequently Asked Questions
How we work, what we deliver, and how we keep integrations healthy after launch.
It starts with a free one-hour consultation: we talk through your systems and goals and give you an honest view of the options. If it makes sense to go further, a short assessment covers systems, auth, data model, and risks, and you get a delivery plan, estimates, and options before we commit to build.
Very likely. We have hands-on experience with Sage Intacct, QuickBooks, Workday, Salesforce, Microsoft Dynamics CRM, HubSpot, ServiceNow, Jira, Azure DevOps, 7pace, Tempo, Google Workspace, KeyedIn, and ProjectAdvantage, and we work with any platform that offers APIs or webhooks, as well as popular iPaaS tools. If your stack has gaps, we'll call them out and propose the lightest-weight fix.
Least-privilege access, secret management, and peer review on every change. We align with your compliance requirements and document data flows.
Runbooks, sequence diagrams, credentials, alert routing, and a short training. Ownership stays with your team, not with us.
Yes. We offer monitoring and response retainers. If you keep support in-house, we still leave alerts and playbooks so your on-call stays confident.
It's your choice. We can deploy to your own Azure, AWS or on-premises environment at no extra cost, or host them for you on managed infrastructure in a UK, EU or USA data centre of your choice, priced by monthly data volume from £60 a month. You can move from our hosting to your own environment later; we'll hand everything over.
