System Architecture

Enterprise-Grade Serverless
Infrastructure. Not a Form Tool.

FlowNexa is built on AWS serverless architecture by a Cloud Computing MSc graduate — not assembled from drag-and-drop tools. Every lead passes through a production-grade data pipeline designed for scale, security, and zero maintenance overhead.

Enquiry Types Qualified

Every Self-Employed
Profile. Pre-Qualified.

The qualification engine captures work type, filing status, income range, expense records, HMRC contact history, and urgency — giving you a complete client profile before your first call.

◆
Uber & Bolt Drivers
Platform gig workers — often unaware of their tax obligations until penalties arrive. High urgency, high conversion.
◆
Taxi & Private Hire
Mixed income streams, mileage records, vehicle expenses — all captured in the qualification flow.
◆
Delivery Drivers
Amazon Flex, Evri, DPD contractors — mileage, equipment costs, and multi-platform income pre-qualified.
!
HMRC Penalty Cases
Penalty letter received — auto-weighted to Hot Lead status. Instant SES alert dispatched to your inbox.
◆
Sole Traders
Tradespeople, freelancers, childminders — business income, allowable expenses, and urgency captured.
◆
Small Business Owners
Early-stage businesses needing help understanding their tax position and filing obligations.
◆
First-Time Filers
Never registered for Self Assessment — guided through the qualification flow, urgency clearly established.
◆
Multiple Income Sources
PAYE plus side income — many don't know they need to declare. High potential for penalty cases.
Data Flow

From Form Submission
to Structured Alert.

The entire lead qualification pipeline executes in under 200 milliseconds — from API Gateway invocation through Lambda scoring to DynamoDB write and SES dispatch.

01
Visitor Submits Form
A POST request fires to your API Gateway endpoint over HTTPS. The payload contains all qualification data — work type, filing status, HMRC history, income range, urgency, and GDPR consent flag.
02
Lambda Scores the Lead
The SaveTaxLead Lambda function receives the event, applies your scoring rules — weighting HMRC penalties, urgency, income, and filing status — and classifies the lead as Hot, Warm, or Cold.
03
DynamoDB + Sheets Write
The structured lead record is written to DynamoDB with a UUID partition key, and simultaneously posted to your private Google Sheet via Apps Script — both operations complete before the SES dispatch.
04
SES Alert Dispatched
A formatted HTML email alert fires via AWS SES containing the lead score, full structured summary, recommended action, and all contact details. Hot leads include an urgent flag in the subject line.
Scoring Engine

Every Enquiry
Weighted and Prioritised.

The scoring engine applies weighted rules across nine variables — you always know which leads represent immediate revenue and which can wait.

◆ Hot Lead · Immediate Action
Call Today
Instant SES alert dispatched. Highest scoring threshold — same-day contact required.
HMRC penalty or late filing notice received
Self-employed income over threshold, unfiled return
Outstanding tax debt or enforcement action
Urgency confirmed as very urgent or imminent deadline
◆ Warm Lead · Follow Up This Week
Call Soon
Qualified and engaged — genuine need with no immediate enforcement. Follow up within 2–3 working days.
Self-employed but not yet registered for Self Assessment
Deadline approaching but not yet overdue
Comparing accountants — ready to decide
Good income record but expenses not yet organised
◆ Cold Lead · Keep on Record
Monitor
Below immediate action threshold — written to DynamoDB and Google Sheet for future follow-up.
PAYE only — no current self-employment income
Just started self-employment, no filing due yet
Recently filed — no immediate need
Below the filing income threshold
Operational Benefits

Stop Triaging Emails.
Start Closing Clients.

Every lead arrives with a complete structured profile — work type, filing status, HMRC history, income range, urgency level, and contact details. No triage calls needed.

◆
Sub-200ms alert dispatch
From form submission to SES email delivery in under 200 milliseconds — Lambda cold start included. Hot leads arrive before the visitor has closed their browser tab.
◆
Persistent DynamoDB storage
Every lead record written to DynamoDB with UUID partition key, ISO 8601 timestamp, vertical identifier, and full scoring breakdown — queryable at any time.
◆
Real-time Google Sheets sync
Simultaneous write to your private Google Sheet via Apps Script — filterable by lead type, score, submission date, and work type. Accessible to your entire team.
◆
GDPR Article 6 compliant
Explicit consent captured and stored on every submission. Lawful basis documented. Data processed in AWS EU-West-2 London region — full UK data residency.
◆
Zero infrastructure overhead
