Paper job sheets waste time — digitize jobs + customer portal

Many small-to-medium trade businesses — electricians, plumbers, HVAC, roofing and general contractors — still rely on paper job sheets that create rework, lost information and invoicing delays; the problem affects technicians in the field, office admins reconciling jobs, and customers who lack visibility. With an addressable pool of roughly 5.0M SMBs and a $6.0B market at a $1,200 ACV suite, the operational friction is both widespread and economically meaningful. You could build a mobile-first field app that captures jobs with offline capability and exports structured data using AI OCR and multimodal extraction (photos, PDFs, voice), paired with scheduling, accounting integrations and a customer portal for quotes, approvals and status tracking. Packaged as an annual subscription at about $1,200 ACV with prebuilt trade templates and open APIs, the product would aim to eliminate paper rekeying and shorten invoice cycles. This market is attractive now because technician expectations have shifted to full mobile capability, AI extraction has reached practical reliability for field documents, and customers increasingly expect self-service portals; those three trends lower the behavioral and technical barriers to adoption. The combination of recurring revenue, clear ROI for customers, and a Market Score of 90/100 with an 88/100 revenue potential suggests a strong commercial runway, though the opportunity is not risk-free. To stand out versus medium competition you must excel on extraction accuracy, offline UX for field use, and a customer-facing portal that’s genuinely simple for non-technical end customers, plus fast integrations to core accounting and scheduling systems. The key challenges are go-to-market (acquiring many SMBs cost-effectively), integration complexity, and data security/compliance; if you can execute on those operational fronts and secure partner channels, the economics and timing look favorable.
