How to build a custom sales quoting app with no-code

A quote is the bridge between an enquiry and a new customer. Yet for too many businesses, generating a quote still means digging through spreadsheets, double-checking formulas, and copying numbers from one document to another, all while a client waits.

Manual quoting processes are time-consuming for sales teams. As your business grows, spreadsheets grow more complex, versions multiply, formulas break, accuracy struggles, and what should take minutes can stretch into hours. 

At Incredible, we’ve helped businesses across industries transform manual, risk-prone quoting spreadsheets into simple, powerful Glide apps. In this guide, we’ll walk through how to build a quoting app, using a real customer example to show what works, why it works, and what changes when quoting gets easier.

How to know you need to update your quoting system

Spreadsheet-based sales quoting can work when operations are small, but it can get increasingly inefficient at scale. Here are some signs your team is ready to move from spreadsheets to custom quoting software:

• Quotes take 30–60 minutes to generate
• You have one “master” spreadsheet that can only be accessed by one person at a time
• Multiple spreadsheet versions are circulating
• You don’t have a connection to live inventory or ERP data
• Sales reps are unable to quote remotely
• You need to do manual discount updates

How to build a quoting app with Glide

You can build your Glide app on top of your existing quoting spreadsheet and design an interface and features for your new quoting tool. With Glide, you can build an app from the ground up without needing to be an engineer. However, if you prefer to enlist experienced help, you can work with Glide Experts and agencies like Incredible.

Here’s a step-by-step framework to follow to build your quoting app:

1. Define the requirements

The first step is to map your quoting process and requirements. What should your quoting app actually do? This is a good opportunity to rethink and improve your workflow.

Typically, businesses will need to be able to:

• Use a single source of truth for pricing
• Generate quotes using simple inputs
• Pull data from a CRM or inventory automatically
• Push quote data back into a CRM or accounting system
• Support mobile quoting in the field
• Add approval workflows
• Produce polished, branded PDF outputs

These details and requirements will guide your application building.

2. Structure your spreadsheet

Before you open Glide, make sure your spreadsheet is organized. You want the data separated into a few clear tables for customers, products or services, quotes, and line items. That gives Glide a clean structure to work with.

For example, your spreadsheet might look like this:

• Customers table: Each row is one customer. Include columns like customer name, company name, email, phone, billing address, shipping address, and account owner.
• Products table: Each row is one product or service. Include columns like product name, SKU, description, category, unit price, cost, tax category, and whether it is active.
• Quotes table: Each row is one quote. Include columns like quote ID, customer ID, quote date, expiration date, sales rep, status, subtotal, discount, tax, total, and notes.
• Quote Items table: Each row is one line item within a quote. Include columns like quote item ID, quote ID, product ID, quantity, unit price, discount, and line total.

The important thing is that each row represents a single thing. One customer. One product. One quote. One quote item. That structure makes Glide much easier to configure.

Next, clean up the spreadsheet so Glide does not inherit confusing data.

Make sure every column has a clear header. Remove blank rows. Avoid merged cells. Avoid putting multiple values in one cell where possible. Use IDs to connect tables. For example, each customer should have a unique customer ID, and each quote should store that customer ID so Glide can link the two together.

Also, try not to rely on spreadsheet formulas for everything. Glide can handle a lot of calculations inside the app, making the quoting workflow easier to manage. Use the spreadsheet as structured source data, not as the final product.

3. Create a new Glide app from the spreadsheet

Now go into Glide and create a new app. Choose your spreadsheet as the data source. Glide supports common spreadsheets and databases, including Excel, Google Sheets, Airtable, SQL databases, and other data sources via custom APIs if needed. Glide syncs with your data using a comprehensive API and a workflow system with webhook triggers that let your systems securely send data to Glide on an automated basis. 

Glide will now automatically generate a rough interface based on your spreadsheet. That initial layout is just a starting point; you can customize it from here. At this point, check that Glide imported the tables correctly. Make sure the Customers, Products, Quotes, and Quote Items data all came in cleanly.

4. Set up relationships between tables

This is one of the most important steps. Your app will not feel like a real quoting system until the tables are connected.

You want Glide to understand that:

• a quote belongs to one customer
• a quote has many quote items
• each quote item points to one product

Inside Glide’s Data Editor, create relationships between these tables. Link the Quotes table to the Customers table using customer ID. Link the Quote Items table to the Quotes table using quote ID. Link the Quote Items table to the Products table using product ID.

Once those relationships are in place, Glide can automatically pull in customer details, display all line items on a quote, and look up product pricing without manual copy-paste.

5. Add computed fields for calculations

Now add Computed Columns. These calculations make the app work like a quoting tool rather than a data viewer.

In the Quote Items table, create a computed value for line total. That is usually quantity multiplied by unit price, minus any line discount if needed.

In the Quotes table, create computed values that roll up all related quote item totals into a subtotal. Then calculate the tax, quote-level discount (if you use one), and the final total.

You can also add computed values for margin, profit, or commission if those matter to your process. When a rep adds or changes a line item, the quote totals should update automatically.

6. Build the main screens of the app

Once the data model is working, start shaping the interface.

A quoting app usually needs a few core views to show quotes, customers, and products or line items. 

Your quotes screen lets users quickly view active, draft, sent, and accepted quotes. Add filters or tabs if needed so reps can focus on their own work.

Next, create a quote detail screen. This is where a rep opens a single quote and sees the customer, quote status, date, notes, line items, subtotal, and total. That detail view is the center of the app where each quote is built, reviewed, and sent.

7. Create your quoting workflow

Now, create the workflow for generating a quote. Instead of opening a spreadsheet and duplicating tabs, the rep will tap a button to start a guided quoting workflow.

Add a button labeled "New Quote." That button will create a new row in the Quotes table. When the row is created, store the key quote details, such as the quote ID, date, sales rep, status, and selected customer. Use the button to send the user directly into the quote detail screen so they can continue building it.

Once a quote exists, the next step is adding line items. Add a button, such as Add Line Item, inside the quote detail screen. That should create a new row in the Quote Items table tied to the current quote ID.

Then let the user choose a product or service. Once the product is selected, Glide can look up the default unit price and description from the Products table. The user can enter quantity and adjust pricing if your process allows that.

As line items are added, the quote detail view should show them in a list. This gives the rep an immediate view of what is included in the quote.

Add forms to make your quote-building process easier. Use forms for things like:

• creating a new quote
• selecting a customer
• adding a line item
• editing quantity or discount
• updating quote notes
• changing quote status

A form turns the workflow into a guided sequence instead of exposing raw table rows. That is especially helpful for sales reps who should not have to think about database structure.

8. Add guardrails to protect pricing

A quoting app becomes much more useful when it reduces mistakes.

Set up roles with permissions and visibility rules so only the right users can change prices, apply discounts, or approve unusual deals. For example, sales reps might be able to build quotes, but only managers can override pricing or approve discounts above a certain threshold.

You can also add validations so that required fields must be filled in before a quote can move forward. That helps prevent incomplete or inconsistent quotes from being sent to customers.

9. Add a button to generate a PDF quote and send it to the customer

Once the quote is complete, the next step is turning it into a document. This is where quoting apps start saving serious time. 

Add a button to “Generate PDF Quote”. You can use Glide’s native print to PDF ability or a DocsAutomator integration to send quote data into a document template in Google Docs or PDF. The template can contain your company branding, customer details, line items, totals, terms, and signature area.

The app will automatically turn the quote record into a polished output, so reps don’t need to rebuild the quote manually in a document or copy and paste data. 

After generating the document, add another action such as Send Quote. That action will change the quote status from Draft to Sent, record the send date, and trigger the email workflow. You can use a send email action or a Gmail integration to load a pre-filled email with an attachment into your sales rep’s inbox. You can use Glide AI to help write a customized email draft as well.

10. Add statuses, dashboards, and views for sales reps and managers

A quoting app should not stop at quote creation. It should also help the team track progress.

Create a status field in the Quotes table and use values like Draft, Pending Approval, Sent, Accepted, Declined, or Expired. Then show those statuses throughout the app.

This lets managers see which quotes are waiting, which are active, and which have closed. It also gives reps a simple pipeline view for follow-up.

Once the core quoting flow is working, build simple dashboards.

A sales rep might need a view of their recent quotes, quotes awaiting action, and quotes expiring soon. A manager might need a broader dashboard that shows total quote value, number of quotes sent this month, approval bottlenecks, or win rates.

This does not need to be complicated. Even a few filtered lists and summary cards can make the app much more useful.

11. Publish the app for the team

Once the app is working, customize the colors and branding, and then publish it and share access with your team. You can email invitations, pin a URL in your Slack channels, or print a scannable QR code. Reps can install the app on their smartphone homescreen or in their laptop toolbar so it feels like a native application.

Once the base app is live, you can keep improving it. You might add approval workflows, customer-specific pricing, recurring quotes, bundles, e-signature steps, CRM syncing, invoice creation, or reporting.

The best approach is to launch a useful version first, then iterate. Start by replacing the manual spreadsheet process. Then expand into a fuller sales operations system.

A real-world example: Tennant replaced slow spreadsheets with a better sales experience

Tennant manufactures and services commercial cleaning equipment globally. Their Australian sales reps are frequently on-site with customers, and need to generate accurate quotes quickly.

The problem:

The sales team relied heavily on Excel spreadsheets for quoting. Creating a single quote could take up to an hour, updates were manual, and version control was messy. The “master” file could only be accessed by one person at a time.

This created delays, risk, and frustration, especially in front of customers.

The solution:

A custom Glide app replaced the spreadsheet entirely.

Now:

• Pricing logic lives securely in one place
• Sales reps simply select products, quantities, and options
• Calculations happen automatically
• Discount rules are built in
• Quotes are professionally formatted
• The app works on mobile, tablet, and desktop, for remote quoting

Because the app was built on Glide, the entire project took weeks rather than months, and new features (like rental options and finance calculators) were easily added later.

The result:

• Quoting time was reduced from 1 hour to minutes
• Significant time savings freed the sales team up to focus on making more sales
• Professional quotes could be created on-site, making it easier to convert leads
• Pricing became more consistent across the business

What started as a spreadsheet fix became a competitive advantage for Tennant’s team.

How different businesses can benefit from a custom quoting app

The sales quoting process can look very different for different industries. One of the biggest benefits of creating custom quoting software is that you can tailor your workflows to your unique needs and incorporate concerns that are specific to your business or industry. Here’s how that can benefit businesses in different industries:

Trades, construction, and field services

Quoting often happens in the field and can be especially difficult because every job is different. Sales teams and project managers often need to estimate costs while accounting for changing conditions in the field, which makes fast and accurate quotes especially important. A mobile-optimized custom quoting app replaces clipboards and allows teams to generate estimates directly on-site.

Custom apps can account for:

• Variable material costs
• Labor differences by site
• Change orders
• Integrated invoicing and scheduling

Manufacturing, distribution, and wholesale

In manufacturing and distribution, quoting is a critical step that directly impacts profitability. Sales teams need to balance competitive pricing with operational challenges, making accurate quotes essential for maintaining margins and keeping deals moving. A custom quoting app streamlines this process by automating calculations and centralizing pricing rules, helping teams produce reliable quotes faster and with greater consistency.

Custom quoting apps can handle:

• Volume discounts
• Custom configurations
• Freight calculations
• Margin protection rules
• Lead-time visibility

Professional services and agencies

For professional services and agencies, quoting is closely tied to defining the scope of work. Getting the estimate right is important not only for winning the project but also for ensuring the work remains profitable once it begins. A custom quoting app allows firms to standardize how estimates are generated while adapting the system to their specific pricing models and client relationships.

Apps can manage:

• Time-based vs value-based pricing
• Blended rates
• Scope creep safeguards
• Client-specific pricing structures
• Integrate with a client portal for a more polished customer experience.

Logistics and supply chain

Quoting in logistics is often time-sensitive and operationally complex. Companies need to generate prices quickly while accounting for multiple variables that can affect the final cost of moving goods. A custom quoting app helps teams produce quotes more efficiently while incorporating the specific pricing logic and operational constraints unique to their logistics network.

Quoting can incorporate:

• Fuel surcharges
• Route variability
• Capacity constraints
• Dynamic pricing

Event and rental businesses

Event and rental companies rely on accurate quoting to plan resources and secure bookings. Because many details can change between the initial inquiry and the event itself, creating clear and reliable quotes is a crucial part of the sales process. A custom mobile quoting app gives teams a faster and more organized way to generate quotes while adapting to the specific pricing structures and operational needs of their events business, even when on site.

Custom apps simplify accounting for:

• Equipment availability
• Multi-day pricing
• Setup/teardown labor
• Last-minute changes
