Use Cases
documentorium
Creating a Detailed Quote or Estimate
An HVAC technician visits a potential customer's home to assess a new installation. Using documentorium on their phone or tablet, they select the "HVAC Quote" template. The guided form prompts them for specific details like system type, BTU requirements, ductwork modifications, and labor hours. In minutes, they can present a detailed, professional PDF quote on the spot, impressing the client and speeding up the sales process significantly.
Managing a Job with Change Orders
A general contractor is halfway through a kitchen remodel when the client requests an upgrade to custom cabinets. The contractor opens documentorium, finds the "Change Order" template, and fills in the new scope of work, materials, and adjusted costs. They generate a clear PDF, have the client sign it digitally or on paper, and instantly have a formal record of the agreement, protecting both parties and keeping the project organized.
Completing Post-Service Documentation
A plumber finishes repairing a leak and needs to provide documentation of the service for the homeowner and their own records. They use documentorium's "Service Report" template for plumbing. The form guides them to list the problem found, parts used, labor time, and any recommendations. The resulting professional PDF serves as a receipt, a warranty record, and a helpful reference for any future service calls.
Submitting a Formal Project Proposal
A solar installer is competing for a commercial project and needs to submit a compelling, detailed proposal. Instead of spending days in a word processor, they use documentorium's "Solar Proposal" template. The structured form helps them outline the system design, energy savings projections, equipment specifications, and financing options clearly. They generate a polished PDF proposal that stands out for its clarity and professionalism, helping them win the bid.
