  • Complete inventory of every spreadsheet, software tool, and manual data touchpoint
  • Detailed issue report exposing silent calculation errors, currency drift, and reconciliation leaks
  • Clean data architecture blueprint showing how all your company data connects without duplicates
  • Working clickable prototype running on a sanitized slice of your actual company data
  • Written implementation roadmap with milestone timelines and a guaranteed fixed build budget

Ideal Fit
Firms doing $1M–$50M in revenue (e-commerce, manufacturing, wholesale, or services) that know their spreadsheets and disconnected tools are breaking, but want an exact plan and prototype before building.

Custom Operational System Build

Core Operational Replacement
What is this and who is it for?

A full-cycle custom software build that permanently replaces brittle spreadsheets, siloed tools, and manual data transcription with an audited, multi-user web application built specifically for your team.

Exact Deliverables Included:

  • Full production system tailored to your exact operational workflow (multi-channel e-commerce fulfillment, plant floor production, or wholesale distribution)
  • Private, enterprise-grade database where team members only see what they have permission to see
  • Fast, mobile and desktop-friendly screens built for error-free daily entry by your staff
  • Automated double-entry ledgers, analytical reports, and real-time reconciliation dashboards
  • Full deployment, staff onboarding sessions, and parallel-run testing until 100% reconciled
  • Complete transfer of 100% source code, cloud billing accounts, and administrative keys

4 to 8 weeks staged build

Safe AI Automation Pipeline

Failsafe AI Pipeline
What is this and who is it for?

An automated operational pipeline for companies that want AI speed without risking database errors or corrupted records. The AI extracts data from incoming documents at high speed, while strict verification checks automatically confirm math, duplicates, and tax IDs before anything touches your real records. Unclear items route to a simple one-click human review queue.

Exact Deliverables Included:

  • Automated ingestion engine for incoming PDF invoices, shipping manifests, purchase orders, and emails
  • Isolated safety net: AI extracts data, but cannot write to real records without passing strict accuracy rules
  • Automated math verification: line items, taxes, totals, and duplicates must balance 100% before saving
  • Interactive exception review queue where your team can review and approve flagged items in seconds
  • Permanent audit log capturing input file records, AI extraction steps, and approval timestamps
Timeline
2 to 3 weeks add-on module
Pricing Structure
From $3,500 fixed scope (includes safety staging & review queue)
Ideal Fit
Operations processing 200+ monthly supplier invoices, shipping manifests, or custom customer orders by hand who want automation without hallucinated accounting errors.
