Data Analytics & Web Scraping

Getting the numbers out of wherever they are sitting — scraped, extracted and cleaned into dashboards and reports that answer a question somebody actually asked.

What this covers

Most reporting problems are not tooling problems. They are definition problems and plumbing problems: two systems disagree about what "active customer" means, or the same figure is keyed in twice and one of them is a week behind. We start by settling what each number means and where it comes from, then build the shortest path from source to screen. That often means scraping public data that has no API, or pulling from an ERP that has one but no usable reports. The deliverable is something a person opens on a Monday morning and acts on — plus the documentation to keep it running when a source changes underneath it.

  • Dashboards built around the questions you ask, not every metric you could collect
  • Scraping that respects robots.txt and rate limits, and tells you when a source changes
  • Pipelines into the tools you already use, rather than one more place to log in

Capabilities

The specifics, rather than the adjectives.

Dashboards people actually open

A small number of screens organised around decisions — margin by product, collections by branch, pipeline by stage — instead of one page carrying every metric the business can produce. A dashboard nobody opens is a reporting cost with no return.

Deciding what to measure first

Every metric gets a written definition: what counts, what does not, which source wins when two disagree, and how often it refreshes. Most disputed numbers in a business are a definition problem wearing a data problem costume.

Web scraping and structured extraction

Pulling data from public pages that offer no API — listings, prices, availability, tenders, directories — into a clean structured table. Where an official API exists, we use it; scraping is for when there is no better option and the data is genuinely public.

Scraping that stays lawful and stable

robots.txt and rate limits respected, no personal data collected without a basis for it, and polite request patterns that do not degrade the source. Plus change detection, so a redesign upstream raises an alarm instead of silently writing wrong numbers into your reports.

Price, stock and competitor monitoring

Watching the sources that matter — competitor pricing, stock availability, listings, tenders — on a schedule, with the changes that are worth acting on surfaced rather than an email containing everything that moved. The value is in the alert, not the archive.

Bulk order processing for marketplace sellers

Taking marketplace exports and turning them into whatever the next system needs: cleaning, deduplicating, reconciling against stock, and producing the upload file or the picking list. Removes the afternoon of spreadsheets that currently sits between an order arriving and it being fulfilled.

Reports that send themselves

The numbers arrive where the decision gets made — a scheduled email, a WhatsApp summary, a PDF for a board pack — rather than waiting for somebody to remember to open a dashboard and rebuild a spreadsheet by hand.

Pipelines into the systems you already run

Extraction from ERPs, accounting systems, CRMs and databases, with the transformations written down rather than living in one person head and three macros. Feeds into SQL Server, Oracle, MySQL or a reporting tool you already pay for.

Data quality you can check

Freshness, duplicate records, missing values and outliers flagged on every refresh, with a visible last-updated time on each dashboard. Trust is built by making the gaps obvious, not by hiding them behind a confident-looking chart.

Removing the manual reporting grind

The copy-paste-and-reconcile routine that consumes a day a week and produces a different answer each time. Automating it is usually the fastest measurable return in the whole engagement, and it is the part that makes a controller trust the rest.

What you get

A concrete list of outputs. If something here is not relevant to your project, it comes out of the scope and the price — we would rather agree that in writing now.

  • A metric definition pass: what each number means and which are trusted
  • A source inventory covering the systems and pages that hold the data
  • Scraping or API extraction with schema validation and change alerts
  • A cleaning and transformation layer, with every rule written down
  • Dashboards or scheduled reports built for the decisions they support
  • Delivery by email, WhatsApp or PDF so nobody has to remember to look
  • Quality checks on freshness, duplicates, gaps and outliers on each refresh
  • Documentation of every source, rule and refresh interval, plus what to do when one breaks

How it runs

Five steps. You always know which one you are in.

  1. 01

    Questions first

    We start with the decisions you make and how often, not with the data you hold. A metric that does not change a decision is a metric that should not be on the dashboard.

  2. 02

    Source audit

    Where every number actually comes from, who owns it, how fresh it is and where two sources disagree. Usually the point at which a long-standing dispute turns out to be a definition problem.

  3. 03

    Extraction

    Scrapers, API clients or direct database reads, whichever the source supports. Built with validation and change detection from the start, because sources break and that failure has to be loud.

  4. 04

    Modelling and dashboard

    Cleaning, joining and shaping into the tables the questions need, then the smallest dashboard or report set that answers them. Iterated with the people who will use it, not demonstrated to them once.

  5. 05

    Handover

    Documentation of every source, rule and refresh interval, and what to do when a source changes. Plus monitoring so you find out from an alert rather than from a wrong number in a board pack.

Stack

The platforms and frameworks we build, integrate and maintain on. We would rather work in a stack your team can hire for and hand over than pick whatever is interesting this year — and where an existing platform does the job better than custom code, we will say so.

  • Pandas
  • SQL

FAQs

Data Analytics & Web Scraping — frequently asked questions

Is web scraping legal?

It depends on what you collect, from where, and what you do with it — this is a legal question as much as a technical one, and we are not lawyers. What we do is keep the technical side defensible: respect robots.txt and the site terms, keep request rates low enough that the source is not affected, collect only what the task needs, and avoid personal data unless there is a clear basis for holding it. Where the answer is genuinely unclear, we will tell you to get it reviewed rather than quietly proceed.

What happens when the site we scrape changes its layout?

This is the failure that gives scraping a bad name, so it is designed for from day one. Every extraction run validates what it collected against an expected shape and checks row counts against recent history. When a source changes, the run fails and alerts rather than silently writing empty or shifted values into your dashboard. Fixing it is usually a small job, and we quote that separately so you can see what ongoing maintenance costs.

Do we need a data warehouse first?

Usually not. For most businesses the right answer is a small set of well-defined tables in a database you already run, refreshed on a schedule. A warehouse earns its place when you have several sources, a real history requirement and people asking questions you cannot predict. We will recommend the smaller thing while it is still the right answer.

Which dashboard tool do you use?

Whichever you already pay for, if it does the job — Power BI and Looker Studio cover most needs, and staying in a tool your team can open without a new licence is usually worth more than a marginal feature elsewhere. Where no tool exists yet, we build a focused web dashboard on your own stack so there is nothing extra to license or learn.

Can you work with the data already in our ERP or accounting system?

That is the usual starting point. Direct database reads where you have access and the schema is stable, a vendor API where one exists, and scheduled exports where neither is available. The audit establishes which of those applies, because it decides most of the effort and the reliability of everything downstream.

How do you handle personal data in analytics work?

By minimising it. Aggregates and identifiers are usually enough for reporting, and where individual records are genuinely needed they are kept in systems you control rather than copied into a reporting tool. Anything that leaves your infrastructure is agreed in writing first, and anything that identifies a person is a deliberate decision rather than a side effect.
