Most consultants diagnose the gap between your field crews and your general ledger. We built the platform that closes it — Field2Bill turns field tickets into QuickBooks invoices, backed by real systems architecture.
The platform
The field-service billing system we engineered in-house — purpose-built for industrial firms that bleed margin between the field and the office.
Billing & QuickBooks
Crews capture tickets on site. Operations approves. Billing sends — straight into QuickBooks Online, where your invoicing and payments already live. No re-keying, no lost billable hours.
Dispatch & field ops
Assign crews and equipment, track who's on site, and capture digital LEM tickets — with expired-certification workers automatically blocked from dispatch.
Owner, Operations, Dispatcher, Billing, and Viewer logins — everyone sees exactly what they need, nothing they don't.
How we work
Software alone doesn't fix a broken billing process. You also need someone who understands the field and the ledger. You get both.
Field2Bill replaces spreadsheets and disconnected tools with one system that runs from the field ticket to the general ledger.
Long architects your data flow and QuickBooks integration so the system runs clean from day one — no learning by trial and error.
Profitability analysis by service line and 13-week cash-flow forecasts to scale your $5M+ firm with confidence.
