1. 50+ campaigns, zero API, one exhausted team
The agency was growing. More clients, more campaigns, more revenue. On paper, everything looked great. In practice, the team was drowning.
Every morning, an account manager would open the Allegro Ads panel and start clicking. Adjust bids on campaign one. Switch to campaign two. Adjust again. Campaign three. Four. Five. By campaign fifteen, the coffee was cold. By campaign thirty, the focus was gone. By campaign fifty, mistakes were inevitable.
Then came reporting. Open each account. Screenshot the dashboard. Paste it into a slide deck. Add the numbers to a spreadsheet. Repeat for every client. Every week.
The agency tried the obvious solutions. They looked for a tool that could manage Allegro Ads in bulk. They asked their developer to build an integration. The developer looked at Allegro and came back with bad news: "There is no API for this. It cannot be automated."
The daily reality
4 hours per day on bid adjustments and reporting. 20 hours per week. 80 hours per month. That is half a full-time employee doing nothing but clicking through the same interface, making the same motions, praying they do not fat-finger a bid and burn a client's weekly budget in an afternoon.
The natural instinct was to hire another account manager. But that would only work until the next wave of clients arrived. The problem was not headcount. The problem was the process.
2. Why nothing on the market worked
Allegro is the largest e-commerce platform in Central Europe. Allegro Ads is its advertising system. Unlike Google Ads or Meta Ads, Allegro Ads does not expose a public API for campaign management. There is no endpoint to adjust bids in bulk. No way to pull cross-campaign reports programmatically. No webhook for anomaly detection.
Zapier, Make.com, n8n – useless
Workflow automation tools need an API to connect to. No API means no connector. No connector means no automation. These tools are powerful when APIs exist, but they cannot help when the platform keeps everything locked behind a web interface.
Generic ad management platforms – no Allegro support
Tools built for Google and Meta do not support Allegro. The platform is simply too niche for global SaaS companies to prioritize. If you manage Allegro Ads at scale, you are on your own.
Scraping – fragile and unreliable
The developer's first instinct was server-side scraping. Spin up a headless browser, navigate to Allegro, extract data. But this approach fights CAPTCHAs, breaks on every UI change, and cannot handle authenticated sessions reliably. It was a dead end.
"It cannot be automated"
The developer was thinking about automation the traditional way: API to API, backend to backend. From that angle, they were right. But they were looking at the wrong door.
The insight that changed everything
An API is a door that the platform vendor chooses to open. But there is another door – the front door. The web interface that the agency team uses every day. That door is always open. A browser extension can walk right through it.
3. How Panel Pro works – automation without an API
Panel Pro is a Chrome extension that injects directly into the Allegro Ads interface. When the account manager opens Allegro Ads, Panel Pro is already there – new buttons, new panels, new capabilities layered on top of the existing UI. No separate dashboard. No context switching. No learning curve.
Bulk bid adjustments
Select all campaigns. Set the bid change – increase by 10%, decrease by 5 PLN, set to a fixed value. One click. Panel Pro adjusts bids across every selected campaign in seconds. What took 2 hours now takes 30 seconds.
Cross-account reporting
Allegro Ads shows data one account at a time. Panel Pro aggregates data across all accounts into a single view. Click "Export" and get a formatted Excel file with every campaign's performance data in 3 seconds. No more copy-paste marathons.
Campaign anomaly detection
Panel Pro monitors campaign metrics and flags anomalies – a sudden spike in cost, a drop in impressions, a campaign that burned through its daily budget by noon. The account manager sees the alert the moment they open Allegro Ads, not three days later in a weekly report.
Private and secure
Everything runs locally in the browser. Client data never leaves the machine. No third-party servers, no data passing through our infrastructure. The extension is distributed privately – only the agency's team installs it.
Under the hood, Panel Pro uses our battle-tested stack: CRXJS (the open-source Vite plugin for Chrome extensions that we maintain – 3,900+ GitHub stars), React, and TypeScript. Our internal library handles automatic re-mounting when Allegro's single-page application re-renders, resilient selectors with multiple fallback strategies, and real-time error monitoring so we know about breakage before the team does.
When Allegro updates their UI – and they do – we push a fix through our CI/CD pipeline in minutes. No app store review queue. No 3-day wait. The team gets the update automatically.
4. The numbers: from 4 hours to 15 minutes
Panel Pro started as a tool for one agency. It became a product used by thousands.

Account manager opens 50+ campaigns one by one. Adjusts bids manually in each. Copies data into spreadsheets. Builds reports by hand. Spends 4 hours on tasks that add no strategic value.
Account manager opens Allegro Ads. Panel Pro is already there. Bulk-adjusts bids in one click. Exports a cross-account report in 3 seconds. Sees anomaly alerts immediately. Spends 15 minutes and moves on to strategy and client calls.
What the agency got back
3 hours and 45 minutes saved every Friday. Per person. Across 10 people, that is nearly 40 hours a week – one full-time position. The agency did not hire another account manager. They gave their existing team a tool that made them 16x faster at the task that was eating their Friday. The team went from burned out to focused on work that matters – strategy, client relationships, growing the business.
5. The business case: automate vs. hire
The agency had a choice: hire another account manager or invest in a tool that makes the existing team faster. Here is how the math works out:
| Hire a person | Panel Pro subscription | |
|---|---|---|
| Time to value | 1–3 months (hiring + onboarding) | Install in minutes, start today |
| Monthly cost | 8,000–12,000 PLN (salary + ZUS + benefits) | 500 PLN/month |
| Scales with clients | Linear – more clients = more people | Same subscription handles 5 or 500 campaigns |
| Error rate | Fat-fingered bids, missed campaigns | Consistent, every campaign every time |
| Knowledge retention | Leaves when the person leaves | Encoded in the tool forever |
| After rate changes | Click each bid one by one (seconds each, hundreds total) + update spreadsheets | Calculates from your current bids (e.g. -20% CPC), not hardcoded values |
| Works at 2 AM | No | Yes |
This is not about replacing people. Account managers, strategists, and client leads are irreplaceable. This is about taking the most repetitive, soul-crushing part of their job and handing it to software.
The agency that built Panel Pro with us did not downsize. They took on more clients with the same team, delivered better results because the team had time to think, and stopped losing good people to burnout.
6. How we work with agencies
Panel Pro started as a single agency's internal tool. Today it has 2,000+ users and over 100 shipped versions. We have been building tools for agencies and e-commerce businesses for over a decade, across 7 EU countries.
If your agency has a workflow that should be automated but "cannot be done" – we have probably solved something similar. Here is how we start:
Free consultation (30 minutes)
You describe your workflow and pain points. We tell you honestly whether automation makes sense and what approach fits – browser extension, workflow automation, or custom product. No sales pitch, no commitment.
Analysis and fixed-price proposal (2–3 days)
We analyze your workflow in detail and deliver a fixed-price proposal. Not hourly billing, not estimates – a fixed price for a defined scope. You know exactly what you pay before we write a single line of code.
Working prototype in days
We build a working version fast. You install it in your browser and test it on the actual platform your team uses – not a mockup, a real working tool. Weekly demos and real feedback loops until it is right.
Deployment and ongoing support
We deploy, monitor, and maintain. When the platform changes or your needs evolve, we adapt. You get a partner, not a one-off vendor. NDA from the first meeting. Seniors only – no juniors learning on your budget.
Your platform has no API? Let's talk.
Tell us what your team does manually today. If it happens in a browser, we can probably automate it – API or no API. Free 30-minute consultation. No commitment, no hidden fees.
