You still send quotes with a Word template and a signature at the bottom. Every price you recalculate by hand, the discounts live in your head, and once it is sent you have no idea who looked at it or when. A quotation app should fix that. But “building a quotation app” means two very different things, and most vendors tell you only half the story. This guide explains the difference, names real prices and helps you pick the route that fits your question. Without the sales pitch.
What is a quotation app?
A quotation app is software you use to create, send, follow up on and manage quotes, without loose Word files and manual math. You pick products or services from a catalogue, the app calculates the price, turns it into a clean PDF, sends it to the customer and tracks whether it was viewed, opened or accepted. Digital signing and automatic follow-up are usually part of the package.
So far everyone agrees. But under that single term sit two routes that work completely differently, cost differently and serve a different purpose. Anyone who is not clear on that difference tends to buy the wrong thing. So every good decision starts here.
“Quotation app”: two meanings
There is a catch buried in this search. “Building a quotation app” gets read two ways, and the search results mix them together. Meaning one is an app you use to make quotes, for your sales or field team. Meaning two is a price quote for having an app built. Two completely different questions.
If you want to know what it costs to have an app built from scratch, you are in the wrong place: read our pricing guide on what building an app costs or the broader explainer on having an app built. The rest of this article is about the first meaning: an application your team uses to draft quotes and close the deal faster.
Off-the-shelf quoting software or a custom quote app?
This is the most important question in the whole guide. Off-the-shelf quoting software is a subscription tool you set up and use right away: templates, PDF, send, sign, done. A custom quote app is built around your own pricing logic, workflow and systems. Off-the-shelf is faster and cheaper; custom fits exactly and grows with you.
Most companies are best off starting with a standard tool. Moneybird, Teamleader Focus, HERO Software (strong in construction and installation) or Offorte cover the ordinary quote flow well. Only go custom when you hit a real limit, not before. That limit almost always sits on one of these points: your prices follow rules no template can handle, you want a product configurator, your field team needs to work offline, or you want the quote flow inside your own platform.
| Off-the-shelf quoting software | Custom quote app | |
|---|---|---|
| Starting point | Ready today, subscription | Build project of weeks to months |
| Pricing logic | Fixed templates and simple discounts | Own rules, tiers, margins, configurator |
| Integrations | Fixed, ready-made connectors | Connects to exactly your systems |
| Ownership | You rent the software | You own the code |
| Price indication | €15 to €50 per user per month | €5,000 to €40,000+ one-off |
| Fits | Standard quotes, quick start | Unique pricing logic or own process |
Not sure whether you actually need a whole platform instead of just a quoting module? Then read the difference between a web app, a SaaS and a custom platform. And if quotes become part of an environment where customers or staff log in, look at building a client portal: examples.
What does building a quotation app cost?
Off-the-shelf quoting software costs roughly €15 to €50 per user per month. A custom quote app as an extension of existing software sits between €5,000 and €15,000. A full custom app with a configurator, pricing rules and integrations sits between €15,000 and €40,000, and a real quote configurator with complex logic can cost €30,000 to €60,000 or more. The price is almost never about the screens, but about your pricing logic and the number of integrations.
| Route | What you get | Indication |
|---|---|---|
| Off-the-shelf quoting software | Templates, PDF, signing, follow-up | €15 to €50 per user per month |
| Custom quote module in existing app | Custom quote screen in your own software | €5,000 to €15,000 |
| Full custom quote app | Configurator, pricing rules, PDF, e-signing, integrations | €15,000 to €40,000 |
| Quote configurator with complex logic | Automatic price calculation per choice, option and tier | €30,000 to €60,000+ |
Do not forget the running costs. A subscription tool you pay per user per month, plus add-ons for extra modules. For custom, budget 10 to 20 percent of the build price per year for hosting and maintenance. The biggest lever on your budget is not the tool, but the preparation. Research by McKinsey found that 45 percent of large IT projects run over budget, and the main cause is a scope that was not sharp enough up front (McKinsey). So know exactly which pricing rules and integrations you need before anything gets built.

When is custom worth it?
Custom pays off the moment a standard tool costs you more work than it saves. That happens at three points: when your prices follow rules no template can handle, when you want something the tool does not offer (offline field work, a configurator, a specific integration), or when you want the quote flow inside your own platform. If your quote flow stays simple, off-the-shelf is almost always the better choice.
The tools to get far without custom are maturing fast, by the way. Gartner expected that by 2025 around 70 percent of new business applications would be built with low-code or no-code, up from less than 25 percent in 2020 (Gartner). Still, that line does not move forever: the moment your logic becomes truly business-specific, no-code stalls and custom earns its keep.
Torn between a no-code solution and true custom? Weigh it explicitly against no-code versus custom automation: when to choose what. Custom only pays off when you hit a real limit.
Which features make a quotation app good?
A good quotation app does more than format a PDF. The features that make the difference sit in the price calculation, the follow-up and the integrations. A product catalogue with your own pricing rules, digital signing, automatic follow-up and a link to your accounting are what actually make a quote faster and more reliable than a Word template.
| Feature | What it delivers |
|---|---|
| Product and price catalogue | Always the right price, no typos or outdated rates |
| Pricing rules and margins | Discounts, tiers and margins applied automatically |
| Configurator | Customer or rep configures, the price rolls out automatically |
| Digital signature | Customer signs online directly, no printing and scanning |
| Automatic follow-up | Reminder when a quote is left hanging |
| Accounting and CRM integration | Accepted quote becomes an order or invoice automatically |
That follow-up is not a side note; it is often the difference between winning and losing. Classic research by Harvard Business Review found that companies responding within an hour of an enquiry were nearly 7 times more likely to qualify the contact than companies that responded an hour later (Harvard Business Review). An app that automatically reminds you of an open quote wins deals you would otherwise forget.
A quotation app that doesn’t connect to your accounting or CRM just creates double work. the wider guide to connecting software. The moment a customer signs, you want the order, the invoice and the customer details to land in the right place on their own. That is exactly where custom wins: you decide which systems the app talks to, instead of bending to the fixed integrations of a standard tool.
How building a custom quote app works
Building a custom quote app runs in four steps: pin down your pricing logic, design the flow, build and integrate, and deliver with maintenance agreements. Most of the work is not in the screens, but in getting your pricing rules sharp and your integrations working reliably. A pretty app on unclear pricing logic ends up costing more than it should.
- Pin down pricing logic and scope (a few days to 1 week). Which products, which discounts, which tiers and exceptions? This is the core: the clearer your pricing rules, the more predictable the build.
- Design the flow (a few days). From first enquiry to signed quote: who does what, which approval is needed, what does the PDF look like? Not every screen, but the route a quote travels.
- Build and integrate (a few weeks to months). The configurator, the PDF generation and the links to your accounting, CRM or stock. This happens in short sprints with a demo, so you steer early.
- Deliver and maintain. Go-live, training for your team and agreements on who keeps it current when your prices or systems change.
Do not want to jump into the full project at once? Start phased with one type of quote and expand as it works. How to approach that sits in building an MVP: approach and phases. You are in effect building the same thing as a web application, because a quote app is exactly that kind of application.
What to watch for: the pitfalls
Most disappointments around a quotation app come not from the technology, but from the choices around it. Four pitfalls show up most often, and all four are preventable up front.
- Choosing custom when off-the-shelf is enough. Do not build your own app for a quote flow that Moneybird or Teamleader handles fine. Test a month with a standard tool first.
- Not pinning down pricing logic up front. Unclear discounts and exceptions are the biggest cost driver. Write down your pricing rules before the build.
- Underestimating integrations. The quote app has to talk to your accounting, CRM or stock. Those links often drive more of the price than the app itself.
- No code ownership with custom. Without ownership you pay the same party for every change. Read why that matters in code ownership and vendor lock-in.
Where do you have a quotation app built?
For off-the-shelf quoting software you go to the tool’s vendor: it is a subscription, not a build project. For a custom quote app you choose a software agency that builds and integrates the whole application. More important than the type of party is what you agree up front.
Ask every provider three things. Do I get a fixed price for a clear scope? Do I own the code? And how do you handle my pricing logic and my integrations? A good partner answers those without dodging. More on that choice sits in software agency vs freelance developer and in our complete guide to building custom software.
How to start concretely
Start with your pricing logic, not with the tool. Write down how you build a quote today: which products, which discounts, which exceptions and which steps to a signed deal. Then check whether a standard tool can handle that. If yes, you are done within a week and cheaper off. If no, you know exactly why you need custom, and you compare every quote on the same scope instead of on gut feeling.
