Every UK business has processes that should run themselves but do not. Invoice approvals stuck in someone’s inbox. Data copied between systems by hand. Onboarding steps that depend on one person remembering the right sequence. The usual response is to sign up for a SaaS automation platform and hope the problem goes away.
Sometimes it does. But for businesses with more than a handful of workflows, or processes that do not fit neatly into a template, the cracks show quickly. Task limits, per-user pricing, rigid connectors, and US-hosted data start creating as many problems as they solve.
We build workflow automation tools that match how your team actually works. You own the code, host it on UK infrastructure, and pay once rather than renting month to month. We are a small London-based development team, and we work mostly with SMEs who have outgrown generic platforms and need something purpose-built.
Why off-the-shelf workflow automation tools fall short
The market is full of options. Zapier offers 9,000+ integrations. Make is cheaper per operation. Power Automate comes bundled with Microsoft 365. Nintex handles complex BPM. They all work well enough for simple, standard automations.
The problems start when your needs are not simple or standard:
- Per-task pricing gets expensive at volume. Zapier charges per task, Make per operation, Power Automate per user or per bot. A mid-market business running 20,000 tasks per month can easily spend £5,000+ per year, and costs climb with every new workflow. There is no ceiling.
- Step and complexity limits. Zapier caps workflows at 100 steps. When your approval chain has 20 branches or your logic needs custom conditional routing, you end up splitting one process across multiple workflows, which makes debugging painful.
- Integrations that look complete but are not. A platform might list Salesforce or Xero as supported, but the connector only covers basic fields. Advanced data like custom objects, multi-currency invoices, or line-item details often requires manual entry or a paid add-on.
- No support for legacy systems. If your business runs an older ERP, a proprietary database, or industry-specific software without a modern API, SaaS platforms simply cannot connect to it.
- US-hosted data by default. Zapier is US-based. Make is EU-based but verify data residency guarantees carefully. For businesses subject to FCA rules, NHS data requirements, or strict GDPR interpretation, cloud-only platforms hosted outside the UK create compliance risk.
- Vendor lock-in is real. Workflows built in Zapier cannot be exported to Make, and vice versa. Migrating between platforms means manually rebuilding every automation. If your vendor raises prices, removes a feature, or gets acquired, you have limited options.
- RPA bots are brittle. Power Automate desktop flows and UiPath RPA automate by clicking through interfaces. When the target application updates its UI, the bot breaks. This creates ongoing maintenance work that is easy to underestimate.
The result is staff who resent the new system, workarounds everywhere, and automation that only covers half of what you actually needed.
What we build instead
We build your workflow automation around the processes you already have, not the ones a SaaS vendor assumes you should have.
Your processes stay intact
We map the software to how your team works today. They keep doing their jobs the same way, minus the repetitive manual steps. Fewer errors, less time wasted, no multi-week disruption while people learn a new way of working.
You pay once and own it
No per-task fees. No per-user seats. No surprise price rises in year two. You own the code and the intellectual property. For a mid-market business, a custom build typically costs less over three to five years than the equivalent SaaS subscription stack, and the result fits your business properly.
It connects to everything you actually use
Xero, Sage, Salesforce, HubSpot, Shopify, Slack, Microsoft Teams, DocuSign, and any industry-specific or legacy system your business depends on. We build direct API integrations, not shallow connectors that miss half the fields. Where a system lacks a modern API, we build custom adapters rather than relying on fragile UI automation.
UK-hosted, UK-compliant
GDPR, Data Protection Act 2018, FCA operational resilience, NHS Data Security and Protection Toolkit, HACCP tamper-evident logging, AML/KYC record retention. We build the relevant compliance requirements in from day one and host on UK infrastructure. No Standard Contractual Clauses. No worrying about where your data actually sits.
Complex approval logic that actually works
Route approvals based on amount, department, vendor category, cost centre, or any combination. Handle delegation when someone is on leave. Escalate automatically when approvals stall. SaaS builders struggle with this kind of multi-branch conditional routing. Custom code handles it cleanly.
Room to grow without re-platforming
We build modular systems. When your needs change or you add departments, we extend what is already there. No migration projects. No hitting platform limits and having to start again on a different tool.
What every solution includes
These are the core modules. Each one is configured for your specific workflows and data:
- Visual workflow designer for defining and updating automation rules without touching code
- Approval engine with multi-level chains, conditional routing, delegation, and escalation
- Integration framework connecting your CRM, accounting, ERP, e-commerce, and communication tools
- Task management with queues, assignments, deadlines, and status tracking
- Immutable audit trail logging every execution, approval, and change for compliance
- Role-based access controls so staff only see what is relevant to their job
- Automated notifications via email, Slack, or Teams for pending tasks, exceptions, and milestones
- Document generation for contracts, invoices, purchase orders, and other repetitive paperwork
- Dashboards and reporting built around your actual KPIs, not generic metrics
- Mobile access to workflows and approvals from any device
- Error handling and retry logic so failed steps are caught and resolved, not silently ignored
- Data mapping and transformation to handle schema differences between systems cleanly
How delivery works
We work in phases. A first-phase MVP typically takes four to six weeks. Larger projects run three to six months.
1. Discovery and process mapping (2-4 weeks)
We interview your team to understand current processes, identify the highest-impact automation opportunities, and document approval hierarchies, integration points, and compliance requirements. We often find that fixing the process before automating it saves considerable time and money. By the end of this phase, you have clear requirements, a prioritised backlog, and a way to measure success.
2. Development (6-16 weeks)
We build the system in sprints, with regular demos so you can see progress and flag anything that needs adjusting before it goes too far. Integration development typically takes one to two weeks per system, depending on API quality. Complex approval logic and conditional routing add one to three weeks.
3. Testing and deployment (2-4 weeks)
We run thorough QA, then your team does user acceptance testing. Rollout is planned to minimise disruption. For multi-department projects, we deploy one team at a time rather than switching everyone over at once.
4. Training and support (ongoing)
Workflow designers get two to three days of hands-on training. End users get one to two hours per department. We include 12 months of support after launch.
Sensible first phase. A typical MVP covers one or two high-impact approval workflows, two to three core integrations (for example, Xero, Slack, and email), basic approval routing, notifications, and an audit trail. This proves value quickly and gives your team confidence before expanding.
What it costs
Custom development costs more upfront than signing up for a SaaS product. But the total cost of ownership tells a different story.
SaaS platforms charge per task, per user, per bot, or some combination. At low volumes, this is cheap. At mid-market volumes (20,000+ tasks per month, 20+ users), costs escalate quickly. Add premium connectors, AI features, support tiers, and storage, and the annual bill can reach £10,000 to £50,000 or more. Enterprise deployments on platforms like Nintex or UiPath can run £30,000 to £500,000 per year.
A custom build works differently:
- MVP (one or two workflows, core integrations): £15,000 to £25,000, delivered in four to six weeks
- Mid-scale platform (five to ten workflows, advanced routing, dashboards): £40,000 to £80,000, delivered in two to three months
- Enterprise platform (20+ workflows, legacy integrations, RPA, multi-department): £150,000+, delivered in six to twelve months
- Ongoing maintenance: typically 10 to 20 percent of the build cost per year
You own the code and the intellectual property. No vendor lock-in. No surprise price increases. No per-task billing that penalises you for growing.
We price based on your specific requirements. In your free consultation we will give you a ballpark figure and talk through how to phase the work if budget is a concern.

Common Questions About Custom Workflow Automation Tools
How does custom development cost compare to Zapier or Power Automate?
A custom MVP with two or three approval workflows and core integrations typically costs between £15,000 and £25,000. A mid-scale platform with five to ten workflows, advanced routing, and dashboards runs £40,000 to £80,000. That sounds like more than Zapier's £20/month starter plan, but the economics shift quickly. A mid-market team running 20,000+ tasks per month on Zapier or Power Automate can easily spend £5,000 to £15,000 per year on subscriptions, add-ons, and premium connectors. Over three to five years, a custom build often works out cheaper, and you own the result.
What's the typical development timeline?
A single-department automation (invoice approvals, employee onboarding) typically takes four to six weeks from requirements to go-live. Multi-system projects with compliance requirements take three to four months. Complex enterprise-wide rollouts involving legacy systems and multiple departments can take six to twelve months, though we deliver in phases so you start getting value early.
How do you handle updates and changes?
We include 12 months of support and updates with every project. Ongoing maintenance typically costs 10 to 20 percent of the original build cost per year. After the support period, we offer flexible maintenance plans or can train your IT team to manage the system themselves.
Can you integrate with our existing systems?
Yes. Common integrations include CRMs (Salesforce, HubSpot, Dynamics 365), accounting software (Xero, Sage, QuickBooks), e-commerce platforms (Shopify, WooCommerce), ERPs (SAP, Oracle, NetSuite), communication tools (Slack, Microsoft Teams), and document signing services (DocuSign, PandaDoc). We also build connectors for legacy systems and proprietary software that SaaS platforms cannot reach.
What about data security and compliance?
Every solution includes encryption in transit and at rest, role-based access controls, and immutable audit trails. For regulated industries, we build in sector-specific requirements: FCA operational resilience and record-keeping for financial services, NHS Data Security and Protection Toolkit compliance for healthcare, HACCP-compliant tamper-evident logging for food and manufacturing, and AML/KYC record retention for customer onboarding workflows. All systems are hosted on UK infrastructure.
Do you provide training for our team?
Yes. Workflow designers and business analysts typically need two to three days of hands-on training. End users who submit forms and approve tasks usually need one to two hours per department. We provide user documentation, video walkthroughs, and role-specific sessions covering request submission, task approval, notifications, and basic troubleshooting.
When does SaaS make more sense than a custom build?
If your workflows are straightforward (standard approvals, notifications, simple data syncs), your integration needs sit within common app ecosystems, and your team is small enough that per-user pricing stays reasonable, a SaaS tool like Zapier or Make is probably the right call. We are honest about this. Custom builds make sense when your workflows drive revenue or compliance, when your integration needs go beyond standard connectors, when per-task pricing becomes unaffordable at volume, or when you need on-premise or UK-hosted deployment.
