How to Build a Quote & Estimate App from Google Sheets with Adalo

Building a quote and estimate app sounds straightforward until you realize the complexity involved: you need real-time pricing calculations, product catalogs that stay in sync, multi-platform access for field teams, and professional PDF generation—all without abandoning the spreadsheet logic your business depends on. Traditional app development means months of work and tens of thousands of dollars, while off-the-shelf quoting software rarely accommodates the custom pricing formulas and workflows you've refined over years.

That's where Adalo comes in. Adalo is a no-code app builder for database-driven web apps and native iOS and Android apps—one version across all three platforms. AI-assisted building and streamlined publishing enable launch to the Apple App Store and Google Play in days rather than months. Combined with SheetBridge integration, you can connect your existing Google Sheets pricing data directly to a polished mobile app, giving your sales team instant access to accurate quotes from anywhere.

Why Adalo Works for Building Quote and Estimate Apps

Adalo is a no-code app builder for database-driven web apps and native iOS and Android apps—one version across all three platforms, published to the Apple App Store and Google Play. This makes it the perfect solution for quote and estimate apps that need to pull real-time pricing data from your existing Google Sheets while giving your sales team professional tools they can use anywhere—in the field, at a client's office, or back at headquarters.

Having your quote app available on both app stores means your team can install it like any other professional tool, complete with push notifications when quotes need approval or when pricing updates sync from your spreadsheet. Instead of juggling browser bookmarks or emailing spreadsheet links, your sales reps get a dedicated app that launches instantly and works offline when connectivity is spotty on job sites.

Your sales team just lost another deal. While they were driving back to the office to build a quote on their desktop spreadsheet, a competitor closed the sale with a professional estimate generated on-site in under five minutes. It's a scenario that plays out daily across field service companies, contractors, and B2B sales teams still tethered to manual pricing workflows.

The good news? That complex pricing spreadsheet you've spent years perfecting doesn't need to be rebuilt from scratch. With tools like SheetBridge and Adalo's no-code platform, you can transform your Google Sheets pricing data into a polished quote app in under four hours—achieving 70% faster quote generation and eliminating the calculation errors that cost your business credibility.

This guide walks you through building a complete quote and estimate app that connects directly to your existing spreadsheet data. Adalo lets you build database-driven web apps and native iOS and Android apps—published to the App Store and Google Play—from a single no-code editor, meaning your sales team gets the same powerful quoting tool whether they're on a phone, tablet, or desktop. No coding required, no rebuilding for each platform, and no more lost deals while competitors move faster.

Key Takeaways

• Field service companies achieve 70% faster quote generation (5 minutes vs 15-20 minutes) using spreadsheet-to-app conversion
• No-code quote apps deliver 95% fewer calculation errors compared to manual spreadsheet processes
• Businesses save $40,000-60,000 compared to traditional app development costs

The Hidden Cost of Spreadsheet-Based Quoting

Your pricing spreadsheet isn't just inconvenient—it's actively losing you money. When field technicians and sales representatives can't access pricing data on mobile devices, they face an impossible choice: delay the quote or manually calculate estimates with high error rates.

Beyond wasting multiple hours per person, accuracy suffers. Spreadsheet-based workflows introduce data entry mistakes and automated app workflows can reduce these mistakes by roughly 40–60% compared to manual spreadsheets. Each error requires rework, damages client trust, and potentially loses the deal entirely.

Why Spreadsheet Workflows Fail Modern Sales Teams

The root cause isn't your spreadsheet's complexity—it's structural limitations. Your pricing data simultaneously manages:

• Product catalogs with hundreds or thousands of line items
• Variable labor rates across service types and regions
• Markup percentages and discount structures
• Customer-specific pricing agreements
• Historical quote data for follow-up and analysis
• Tax calculations across jurisdictions

Mobile phones can't properly open complex Excel files. Even when they do, formulas break, formatting disappears, and data entry becomes nearly impossible on small screens. Your salespeople resort to taking notes on paper and creating quotes hours later back at the office.

Studies confirm this frustration. When employees work with outdated technology, productivity suffers across every metric. The sales team that could close deals on-site instead schedules follow-up meetings, giving competitors the window they need.

Peak Failure Points in Quote Generation

Spreadsheet-based quoting fails at predictable moments throughout your sales cycle:

Client Meetings (Critical): The prospect asks for pricing during the presentation. Your salesperson opens a laptop, waits for the spreadsheet to load, and manually calculates while the client's enthusiasm fades.

Field Service Calls (Time-Sensitive): The technician identifies additional work needed but can't provide an immediate estimate. The customer says they'll "think about it"—and rarely calls back.

Multi-Location Teams (Consistency): Different spreadsheet versions circulate across offices. One team uses outdated pricing while another applies incorrect discount structures.

Remote Work (Access): The spreadsheet lives on a shared drive that requires VPN access. Remote workers either can't access pricing or use cached versions that haven't been updated.

Traditional Solutions No Longer Work

The Custom Development Trap

Hiring developers to build a custom quote application seems logical until you calculate true costs. Traditional app development costs range from $40,000-60,000 for basic functionality, with 20% annual maintenance on top. The timeline stretches 6-12 months minimum, during which your team continues losing deals.

Off-the-Shelf Software Limitations

Generic quote software rarely matches your specific pricing structure. You'll spend weeks configuring it, then discover it can't handle your discount rules or multi-tier pricing. Customization costs add up, and you're still managing data in two places—your original spreadsheet and the new system.

The Sync Problem

Any solution requiring manual data synchronization between your spreadsheet and application creates failure points. Someone forgets to update the app, prices diverge, and customers receive conflicting quotes from different team members.

Technology Solutions That Actually Work

No-Code Platforms Transform Spreadsheet Data

No-code platforms have fundamentally changed how businesses convert spreadsheet data into functional applications. These systems deliver capabilities that traditional development can't match on similar timelines or budgets:

• 10x faster application delivery compared to traditional coding
• Visual development interfaces requiring no programming knowledge
• Real-time data synchronization eliminating version conflicts
• Native mobile publishing to iOS and Android app stores
• Immediate updates that push to all users simultaneously

The transformation happens in hours, not months. Organizations report building functional prototypes in 3 hours, testing with real users, and iterating based on feedback—all before a traditional development team would finish writing specifications.

Enterprise-Grade Capabilities Without Code

Modern no-code app builders provide comprehensive development environments including:

• Custom formula systems with mathematical functions (ROUND, SQRT, EXP, INT, ABS, LOG) for pricing calculations
• Magic Text integration pulling dynamic data from spreadsheets, user inputs, and database records
• API connectivity linking to external systems, payment processors, and CRMs
• Offline functionality for field teams without consistent connectivity
• Role-based permissions controlling who can view or modify pricing data

Connecting Google Sheets to Your Quote App

The bridge between your spreadsheet and a functional application determines how smoothly your system operates. Three primary methods exist, each with distinct advantages.

SheetBridge: The Fastest Path

SheetBridge provides the simplest conversion process. Authenticate your Google account, select the target spreadsheet, and the system automatically detects your schema. Within 30-60 minutes, you have a functional Adalo database mirroring your spreadsheet data with real-time bidirectional sync.

Changes in your spreadsheet reflect in the app within seconds. Updates made in the app write back to the spreadsheet automatically. There's no manual sync process to forget, no version conflicts to resolve.

Setting Up Your Google Sheet for Integration

Before connecting any spreadsheet to an app platform, clean data structure determines success:

• Place clear column headers in Row 1 (Product_Name, Unit_Price, Quantity, Labor_Rate)
• Remove all merged cells—they prevent proper import
• Create unique ID columns for each record
• Separate related data into distinct sheets (Products, Customers, Quote_History)
• Eliminate empty rows and complex formula arrays

This preparation typically takes 2-3 hours depending on your existing data quality, but it prevents 80% of integration failures.

Mapping Data to App Collections

Once connected, your spreadsheet columns become database fields in your application. The Google Sheets integration supports up to 10 million cells, translating to roughly 500,000 rows in a 20-column database—more than sufficient for most pricing catalogs.

Designing Your Quote App Interface

With data connected, the visual design process begins. Adalo's drag-and-drop builder lets you create professional interfaces without design experience.

Crafting User-Friendly Quote Screens

Effective quote apps follow consistent patterns:

• Product selection screens displaying catalog items with images, descriptions, and base pricing
• Calculator interfaces with input fields for quantities, hours, and custom variables
• Quote summary views showing line items, subtotals, taxes, and grand totals
• Customer information forms capturing contact details for quote delivery
• History screens tracking previously generated quotes

The app templates available in the marketplace accelerate this process, providing pre-built screens you customize rather than building from scratch.

Implementing Dynamic Calculations

Adalo's Magic Text system handles complex pricing formulas. Click the "M" button in any text field, select "New Formula," and build calculations like:

ROUND((Base_Price * Quantity) + (Labor_Rate * Hours)) * (1 + Markup), 2)

The ROUND function controls decimal places for currency display. Conditional visibility hides results until users complete required inputs. Custom formulas support 10+ mathematical functions for sophisticated pricing logic.

Real-World Success Stories

Field Service Pricing Transformation

A service company connected their Google Sheets product catalog to Adalo via SheetBridge. The mobile app calculates quotes using the formula: base cost times quantity, plus labor rate times hours, multiplied by markup, minus any applicable discount.

Results after deployment:

• 70% faster quote generation (5 minutes vs 15-20 minutes)
• 95% fewer errors from automated formula calculations
• Instant client quote delivery via email directly from the app
• Time to value: Immediate productivity gains after 1-week deployment

Real Estate Investment Calculator

Real estate investors transformed Excel financial models into a mobile app calculating cap rate, cash flow, and ROI instantly. The app handles complex formulas including monthly mortgage calculations and multi-variable returns analysis.

Outcomes included:

• 3x faster deal evaluation (analyze 5-10 properties in time previously needed for one)
• Instant scenario modeling (change down payment, see immediate ROI impact)
• Mobile decision-making at property showings
• $25,000 saved by one investor who identified an overpriced property through rapid analysis

Why Adalo Stands Apart for Quote Applications

While multiple no-code options exist, Adalo delivers unique advantages specifically designed for businesses converting spreadsheet data into professional applications.

SheetBridge: Your Spreadsheet-to-App Solution

SheetBridge represents Adalo's purpose-built solution for spreadsheet conversion. Unlike generic integration tools, SheetBridge was designed specifically for transforming Google Sheets into native applications:

• Automated schema detection identifies column types without manual configuration
• Bidirectional real-time sync ensures spreadsheet and app data match within seconds
• 30-60 minute setup versus hours of API configuration
• No technical knowledge required—if you can share a Google Sheet, you can use SheetBridge

This matters because alternative methods require significantly more effort. Zapier integration demands workflow configuration with a 14-step process. External Collections API requires Professional plan access and understanding of REST endpoints. SheetBridge accomplishes the same result in a fraction of the time.

Native Mobile Publishing

Unlike web-only competitors, Adalo publishes native apps to the Apple App Store and Google Play Store. Your quote app appears on the home screen alongside other business tools. Offline functionality lets field teams generate quotes even without cellular signal—calculations execute locally, syncing when connectivity returns.

Marketplace Components

The component marketplace offers pre-built elements for quote applications: payment processing via Stripe, PDF generation for professional quote documents, email delivery systems, and signature capture for approvals. Each component undergoes rigorous testing to meet Adalo's quality standards.
