Custom Field Service Operations & Dispatch ERP Software
Connect your field technicians, track truck inventory, and automate customer contract billing in one unified system.
Value-basedFixed-Scope Projects
HVAC and commercial field service companies juggle PM contracts, emergency dispatches, truck parts, and billing that must sync back to QuickBooks. Generic field-service SaaS stacks charge per technician per month and still leave you in Google Sheets for dispatch. We build custom field service ERP databases on Access, SQL Server, Excel, Google Apps Script, and Power BI. Technicians get simple mobile-friendly workflows; the office gets one source of truth. You own the system — no perpetual per-user license fees.

You Own the System — No Per-User SaaS Licenses
Commercial ERP vendors charge per user, per month, forever — often $150–$400+ per seat before add-on modules. We build custom ERP databases on SQL Server and Microsoft Access (with Excel and Power BI where it helps). You own the code. Projects typically start at $1,200 for focused scopes; larger plants and multi-site rollouts are quoted after discovery. Build it once, run your operation without license creep.
Operational Problems We Solve
PM contract revenue leaks
Track visit schedules, contract tiers, and billed versus performed maintenance before renewals slip.
Dispatch chaos
Assign jobs by skill, zone, and parts on the truck with automated notifications instead of group-text fire drills.
Truck stock unknowns
Know what parts each van carries, what was used on site, and what to restock before the next route.
Double entry into accounting
Push completed work orders and invoice lines to QuickBooks once — not re-keyed from paper tickets.
Why Hire Excel Access Expert for Custom ERP?
We specialize in lightweight operational systems for businesses that have outgrown spreadsheets but do not need a Fortune 500 ERP.
🎯
Micro-vertical focus
We target the exact workflows packaging plants, job shops, batch blenders, and HVAC service teams need — not generic manufacturing templates.
🛠️
Fixed-scope delivery
Written scope, fixed quote, and phased milestones so you know cost before we write production code.
📈
Grow into SQL Server
Start with Access for speed; upsize to SQL Server when users, data volume, or uptime requirements demand it — without rebuilding from scratch.
🤝
Shop-floor adoption
Screens designed for scanners, gloves, and minutes between jobs — because ERP fails when operators won't touch it.
What Your Custom ERP Includes
Modules are tailored to your plant or service operation — not a bloated suite you will never use.
Dispatch & scheduling
Drag-and-drop boards or Google Sheets dispatch views with Apps Script alerts to techs and customers.
Mobile work orders
Technicians capture labor, parts, photos, and customer sign-off from a phone-friendly Access web or Sheets form.
Vehicle inventory tracking
Parts issued from truck stock, transferred between vans, and reordered against min/max levels.
QuickBooks integration
Sync customers, invoices, and time entries via API or VBA so accounting stays aligned with operations.
Service analytics
Power BI on first-time fix rate, contract profitability, and parts margin by technician or region.
