Most invoicing apps were built for retail shops selling boxed products, not civil engineers coordinating structural concrete pours, steel tonnage, and complex milestone releases

Compiling a complete Bill of Quantities (BOQ) no longer requires spending hours behind a desktop spreadsheet cross-referencing paper rate sheets. On an active construction site, a civil engineer can assemble an itemized, structurally grouped, and mathematically locked BOQ in minutes directly from a smartphone.
Building a BOQ on the Griham Quote app connects site takeoffs with pre-calibrated material rates, waste factors, and statutory tax compliance, turning raw dimensions into an authoritative client proposal before leaving the job site.
The Anatomy of an Engineering-Grade BOQ
A defensible BOQ must provide complete transparency without exposing internal profit margins. Every item in your Griham Quote project file contains five core data points:
Stable Item Reference & Trade Group: Organized hierarchically by phase (e.g., 01. Substructure, 02. RCC Superstructure, 03. Masonry & Plastering) to keep multi-page bids navigable.
Unambiguous Technical Specification: Descriptions that cite exact material grades, mortar ratios, and Indian Standard (IS) codes (e.g., "Providing and pouring design mix M25 grade concrete including shuttering, propping, and 14-day curing as per IS 456").
Localized Measurement Units: Native trade units—such as Cubic Feet (CFT) or Brass for coarse aggregate and sand, Square Feet or Square Meters for plastering, and Kilograms/Metric Tons (MT) for Fe550 TMT rebar.
Quantity Takeoff: Net measured dimensions taken directly from structural sheets or laser site measures.
Composite Unit Rate: A consolidated rate that bundles raw materials, skilled trade labor, equipment hire, and target margins into a single per-unit value.
4 Steps to Build Your First BOQ in Griham Quote
Step 1: Configure Project Identity & Place of Supply
Tap Create New Project and establish the contract baseline:
Enter the client's legal name, primary billing address, and WhatsApp contact.
Specify the physical Site Address and select the statutory Place of Supply (POS) state code (e.g.,
32 - Keralaor29 - Karnataka).Tag the project type (Residential Turnkey, Commercial Shell, or Interior Fit-out) to load default phase templates.
Step 2: Add Structural Phases & Composite Line Items
Rather than typing repetitive lines from scratch, populate the BOQ using the app's master item catalog:
Select Phase 1: Substructure. Tap to insert Site Clearing & Grubbing, Mechanical Foundation Excavation (CFT/Cum), and PCC 1:4:8 Footing Bed.
Select Phase 2: Superstructure. Tap RCC M20/M25 Columns & Beams and Fe550 TMT Rebar Tying. The app automatically applies your pre-configured wastage factors (6% for steel laps and cut ends; 10% for mortar shrinkage) so your procurement quantities remain accurate.
Enter the takeoff quantities measured from the drawing set. The app calculates line-item totals instantly, eliminating arithmetic formula errors.
Step 3: Define Exclusions and Project Milestones
Protect your firm from unbilled scope creep by establishing contractual boundaries before delivery:
Use the Exclusions Toggle to explicitly state items outside the contract plinth (e.g., Panchayat/Municipal connection tariffs, external road paving, and compound boundary walls).
Switch to the Milestones Tab to distribute the total contract sum across structural stage gates: a non-negotiable 15% Mobilization Advance, followed by Plinth, Slab pours, Masonry/Finishes, and a 5% Retention buffer.
Step 4: Lock Validity and Export the Proposal
Set a 14-day validity expiration date to shield your estimate against sudden market price hikes in cement bags or steel tonnage.

Manual Spreadsheet BOQ vs. Griham Quote Mobile Workflow
Operational Step | Traditional Desktop Excel Sheet | Griham Quote Mobile Engine |
Setup Time | 3 to 6 hours of formula drafting and cell formatting | Under 10 minutes using pre-saved phase libraries |
Formula Errors | High risk of broken | 100% automated arithmetic and quantity multiplication |
Price Updates | Manual overwriting of individual cell formulas | One-tap material price adjustments across all composite items |
Mobile Viewing | Clunky desktop grid requiring pinch-to-zoom on phones | Mobile-responsive, high-resolution vector PDF layout |
Contract Conversion | Requires printing, physical meeting, and manual signing | Instant on-screen digital signature captured on-site |
Billing Integration | Disconnected; requires retyping items into invoice templates | Converts approved BOQ phases into GST tax invoices in one tap |
On-Site Delivery: From Estimate to Contract
Once the line items are locked, share the proposal directly through the client's preferred channel. Handing your smartphone to the homeowner on site allows them to review the itemized breakdown, clarify specifications, and sign the digital acceptance box directly on the glass.
The app immediately compiles the executed agreement into a tamper-proof PDF, timestamps the document, and transmits copies via WhatsApp and email to all stakeholders. By replacing manual paperwork with a structured digital BOQ workflow, you present immediate engineering authority, protect your margins against site waste, and secure client commitments while your competitors are still drafting spreadsheets.
