Six symptoms

Six signs that are costing your business real money

See how many of these you have. Each one represents a specific bottleneck that can be fixed.

01

The customer calls with questions instead of looking up the price themselves

The level of chaos increases as the number of salespeople grows. The configurator handles this task without taking up their time, and the customer receives the price, specifications, and compatibility information directly.

02

The salesperson spends 30+ minutes making an offer instead of 2–3 minutes

Every change to a variant = a new calculation, a quote as a PDF, and no consistent template. Automated quoting reduces this to 2 minutes.

03

Every week, the same questions from customers. Salespeople just recite the catalog

A salesperson repeats the same thing 50 times a month instead of closing the sale. That’s time that’s never coming back.

04

No new leads. Salespeople are saving the day with cold calls and old databases

Without a process for acquiring new customers, you’re creating a hole at the top of your sales funnel. Ads + landing page + CRM together form a system, not chaos.

05

After the sale, the customer has no tools from your company

A customer makes a purchase → and then disappears from the radar. No data for upselling, no relationship. A customer-focused app closes this gap.

06

Every new salesperson spends 2–3 months learning the ropes from scratch

No documentation = every departure means 2–3 months of lost productivity. Processes documented in tools, not in people’s heads.

I had the pleasure of working with this company, I have nothing to complain about, I will even say that I am surprised. I'm usually a mega-believer and there are many rounds of graphic design fixes, here there was only one round of minor changes. We made a page with a configurator together, the whole thing came down in about 9 weeks - which I think is a cool term. I recommend, I will probably come back and more topics!

For us, the company acts as a technological partner who not only programs, but also plans, advises and takes on the burden of technical decisions, which allows us to focus on business development.

Once deployed, the system works noticeably faster, and users immediately noticed the difference. A big plus for stability and refinement of details.

The cooperation was very concrete. First, they carefully analyzed the processes, then they proposed solutions that really accelerated the operation of the system.

The team covers the topic holistically, from concept to implementation. There was no need to keep an eye on the technical details, everything was on their side.

"

A big plus for the approach to UX and the logic of the system. There was no „let's do it because we can”, just a thorough rethinking of the user's structure and experience. The end result is fast, stable and legible even for non-technical people.

Tell us where your sales are dropping off

30 minutes. You’ll walk us through your process: sales reps, leads, quotes, and implementations. We’ll give you our honest opinion on whether a configurator, automated quoting, a lead generation system, or a custom client app makes sense for your business. After the call, you’ll receive a preliminary cost estimate and a decision on whether we’ll be able to help you.

↓How long does the conversation last?
About 30 minutes. To be precise, without beating around the bush.
↓Is it payable?
No. The first consultation is free and there's no obligation.
↓Does it commit to anything?
No. You receive a diagnosis and an initial cost estimate—you make the decision yourself.
↓What if the process is non-standard?
All the better—that’s exactly the kind of processes we implement, tailored to your business.

Typical questions and objections

We answer our customers' questions before they even ask them.

↓How much does it cost?
The cost depends on the scope of implementation - from process diagnosis to full system transformation. At the first conversation (free of charge) we will define the scope and give a specific quote. Rule of thumb: first decisions, then budget. No commitments.
↓Do we need to change the CRM/system?
Not always. We integrate what you have if it works. Often the problem is not the system, but the processes. If the system is blocking scaling, we will suggest a change, but we determine business decisions first, then technical ones.
↓We already have CRM. Why do we need JSON Hub too?
CRM stores contacts and history—JSON Hub does what CRM doesn’t: it generates an offer as a web page in 2 minutes, calculates discounts per customer, and shows who opened the offer, when, and for how long. We integrate it with your CRM; we don’t replace it—it’s a layer for generating offers and upselling on top of what you already have.
↓How do you deal with trader resistance?
Salespeople don't resist processes, just changes without meaning to. If the system makes things easier (automatic reminders, less manual typing), resistance disappears. We implement with team participation, training, feedback. The responsibility for implementation lies with us.
↓What if the process is custom / very specific?
All the better. That’s exactly the kind of processes we implement—tailored to your business, not „off-the-shelf.” First, we understand how your sales operate; then we design a system that supports that. Anyone can implement standard processes.
↓How long does it take to fully implement?
It depends on the scope: analysis takes 1–2 weeks, decisions take 1–2 weeks, and implementation takes 2–4 months. But the first results (e.g., automatic lead assignment) are visible as early as 2–4 weeks after the start of implementation. A full transformation takes 3–6 months, but you don’t have to wait for the „end of the project”—you see results as they happen.
↓Does it require a lot of commitment on our part?
Yes and no. You make strategic decisions, provide access to systems, attend sessions. We take responsibility for the analysis, the design, the implementation, the result. You don't have to be a technology expert - we do it. You decide, we implement.
