Quickcalc Quickcalc Quickcalc Quickcalc

It is a desktop application for Linux that runs offline, installs in seconds, and gives you a 30-day free trial with no account to create. A one-time licence replaces the spreadsheet you have been rebuilding for every listing.

The fees most sellers cannot easily track — in one place

Most sellers know their marketplace takes “a fee”. Fewer can say exactly how much they take once every charge is applied. Quick Calc models the fee types that matter: the final-value or commission percentage each marketplace takes on a sale; regulatory fees such as eBay’s compliance charge; VAT on fees, handled correctly with a simplified view for home sellers; fixed order and per-item fees — the flat charges added per order or per item; enforced ad fees, the fixed advertising percentage you cannot opt out of on platforms like Etsy; charity donations and top-rated or seller discounts; low-order threshold penalties charged when an order falls below a set value; category fees for higher-rate categories like electronics or watches; and foreign-sale fees for orders shipped internationally.

That is 15 fee types modelled in one place, per marketplace.

Ten marketplaces built in

Quick Calc loads default fee values for each marketplace — eBay, Etsy, Shopify, Facebook Marketplace and more — so you start from a realistic baseline rather than a blank form. You can edit those defaults to match your actual account, because the rates your account sees are not always the rates the help page quotes.

The numbers that decide whether to list

Press Calculate and Quick Calc rolls every cost into the numbers that matter: your net sale, total costs, profit, margin, and the exact break-even price — the price at which the item stops losing money. The break-even price is the single most useful number a seller can have before listing. It tells you the floor below which you should not sell, before you have committed to a listing that loses money.

Alongside the main calculator, focused mini-tools answer the what-if questions sellers face every day: a VAT tool to add or remove VAT on any figure; a margin calculator to work from a cost and desired markup to a sale price and margin; a discount calculator to see instantly what 5%, 10% or 20% off does to a price; and a free shipping calculator to decide whether free postage still leaves a profit.

Why a spreadsheet is not the answer

A spreadsheet rebuilt for every listing misses fee logic that changes between marketplaces, gets VAT on fees wrong more often than not, does not compute break-even automatically, stays static and out of date when marketplaces change their rates, and offers no built-in tools for the what-if questions. Quick Calc keeps the logic in one place, handles VAT on fees correctly, computes break-even automatically, notifies you of updates, and includes live help and built-in tools for recovery.

Quick Calc Marketplaces for Linux is a product of CritchCorp Computers Ltd. The free 30-day trial is fully functional — continued use after the trial requires a licence. Fee and profit figures are estimates based on the values you enter and the rates available at the time; marketplaces change their fees, and actual results vary. Always confirm final charges with your marketplace.

Pc Audit Pc Audit Pc Audit Pc Audit Pc Audit

PC Audit does that from a USB stick, in around 10 seconds, on Windows or Linux, with no installation on the machine being audited and nothing left behind when the stick is removed.

Reading the report — what matters for a repair shop

The processor line tells you the model, the number of physical and logical cores, the clock speed and the current load. That is the headline spec — the number the customer usually wants to know, and the number you need before you quote a processor upgrade or explain why a machine is slow.

The memory section is where PC Audit earns its keep for a repair shop. It lists total, used and available memory, and then gives you a per-slot table — slot number, manufacturer, DDR type, speed, capacity and part number for each stick. That is the information you need to quote a RAM upgrade precisely. You can tell a customer exactly which stick to buy, in what capacity, without guessing or opening the case to read labels off existing modules.

The storage section lists physical drives — model, serial, interface and size — and logical partitions with drive letter, type, size and free space. That catches failing drives before they fail completely, and gives you the serial number you need for warranty claims. The partition layout tells you whether a machine is running out of space on the system partition, which is often the real reason a customer thinks their computer is slow.

The software list shows what is installed, with versions. That is useful for spotting outdated or unwanted software during a clean-up, and for recording what is on a machine for asset or compliance purposes.

The system log section flags recent errors worth investigating. Not every log entry is a problem, but the ones PC Audit highlights are the ones that suggest a drive that is starting to fail, a service that is not starting, or a hardware event worth looking at before it becomes a return.

Quoting upgrades with certainty

The per-slot memory detail is the single most useful section for a repair shop that quotes upgrades. Instead of telling a customer “you need more RAM” and leaving them to figure out what kind, you can say “your machine has two DDR4 slots running at 2666MHz, one stick of 8GB in slot 1 and one empty slot, so a single 8GB or 16GB DDR4-2666 stick in slot 2 will double your memory.” That is a quote the customer can act on, and a quote you can stand behind.

Sending the report

The report is a PDF. You can save it and attach it in your usual email program, or use the built-in SMTP option to send it automatically — enter your server details once, confirm them with the Test button, and the PDF is attached and sent from the app. Either way, the customer or site contact gets a clean document they can print, file, or forward.

PC Audit is a product of CritchCorp Computers Ltd. One USB licence covers Windows and Linux. The report is a single A4 PDF per machine. Nothing is installed on the machine you audit.

Pdf Pilot Pdf Pilot Pdf Pilot Pdf Pilot Pdf Pilot

PDF Pilot does all four of those jobs in one clean window, on your own machine, with nothing uploaded anywhere. It is built for Linux as a self-contained file that installs in seconds and leaves no trace behind. A 30-day free trial gives you the full feature set with no account to create and no data collection of any kind.

Four tools, one window, zero cloud

Most people who need to work with PDFs regularly end up juggling a few different tools — an online merge site for one-off jobs, a separate compressor, something for rotation. PDF Pilot puts them all in a single window with a tab for each job. Pick a tab, choose your file, press the button. That is the whole interaction.

The merge tool combines several PDFs into one, in whatever order you choose. The split tool breaks a large document into single-page PDFs, or extracts only the pages you specify — “1,3,5-8” is the kind of expression it understands. Rotate turns every page 90, 180 or 270 degrees, which is exactly what you need after a scan comes out the wrong way. Compress shrinks a PDF and shows you immediately how much smaller the result is, so you can decide whether it is small enough to email before you send it.

Everything stays on your machine

The difference between PDF Pilot and an online uploader is not just convenience — it is where your documents go. An online converter takes the file you upload and processes it on someone else’s server. With PDF Pilot, the file never leaves your computer. For personal documents, contracts, or anything you would rather not hand to a third party, that distinction matters.

The same applies to an Adobe subscription. You pay once for a PDF Pilot licence, and the software keeps working. There is no monthly fee, no forced upgrade cycle, and no account that needs managing. Updates are offered automatically — you install them or ignore them, your choice.

Linux support built in

PDF Pilot for Linux is a native build, not a compatibility layer or a web wrapper. It installs into your applications menu like any other desktop program and runs from there. There is also a Windows version if you ever need to work across both platforms — purchase a licence from the store.

The free 30-day trial is fully functional. There is no feature gating, no watermark, and no account to create before you download. Run a real PDF through it — merge two documents, compress a file that is too large to email, straighten a scan — and compare the result with whatever you were doing before.

What PDF Pilot is good for

• Combining several PDFs into one document before sending it to a colleague or client
• Breaking a large PDF into single pages or extracting the specific pages you need
• Straightening scans that came out rotated after scanning
• Shrinking PDFs so they fit email attachment limits or upload faster
• Working with PDFs offline, with no internet connection and no third-party server involved
• Anyone who wants the everyday PDF jobs done in one place without paying monthly

PDF Pilot is a product of CritchCorp Computers Ltd. The Linux version runs on 64-bit Linux distributions. You can purchase a Windows version from the store if you need both platforms. The 30-day trial is fully functional — continued use after the trial requires a licence.

Free delivery or postage is something that many people look for when shopping online. It makes it easier in some cases, rather than having to add shipping, which can vary greatly from shop to shop.

Calculating shipping costs, from a customer point of view, can be a nightmare. It can depend on many factors, such as how many items you are purchasing, how heavy they are and where they are going to. For retailers, these are pretty much the same nightmares. Trying to get the prices for shipping just right. Not too much, but not too little.

Those who don’t like free delivery

Do you know anyone who spends the time to create a spreadsheet, showing the price and the delivery and the total? I do. They used to do that but got so annoyed with the fact that after doing as much research as they could. Finding the right price with the right shipping fees (sometimes including the free delivery options), they then found when they got to the check-out and the delivery fee had changed. This meant that they had to go back to the drawing board, or more often than not, just put up with the new price.

Free delivery is the preferred method for many Millennials & Gen Z shoppers. This is because it appears easier and cheaper to do so. In many cases, it is cheaper to shop this way. It can be cheaper as well. The perception of it being cheaper is in the wording, “Free Shipping”. This gives the impression that it is free. As we all know, nothing is free in this would. Free shipping is actually included in the price you pay.

Free postage on everything

We have made our online shop to have included shipping (or free delivery if you like) on everything. This of course means that it is included in the price. If you then by 2 of any item, the same or not, you have paid for delivery twice. Sometimes this may be necessary. For instance, if the shipments are coming from two different locations or warehouses, then it may require two shipping packages. However, if they are coming from the same place and in the same package, then it is not necessary. That is why we have implemented a discount scheme that take this into account. If you order 2 or more of anything, you automatically get a discount on the item price. This means we give back to you the extra cost of delivery that are not needed. You save money automatically. Have a look at our shop and see.

Make sure when you shop online that you are not over paying because of free delivery. If you only buy one item, free shipping is usually well worth it. Getting more than one of anything, and you need to be aware of just how good, or not, the deal is.

Prime Delivery or Free Delivery

Some people have begun to notice that the Amazon Prime shipping is not all that it use to be. Mainly because you have to pay for your prime membership, then you have to pay for Prime delivery. Actually it is a Free Shipping method, that shows very clearly that it is included. Ever tried to compare prices and found that the exact same item is available with prime shipping and without. The prime shipping one will be, in some cases, far more expensive than the non-prime version. That is because Amazon charges sellers far more for the delivery of Prime products from their warehouses.

Prime may well be worthwhile as they do tend to deliver actual next day and even on weekends. The cut-off time is very late as well. This means it may well be worth paying the extra for it to be delivered, but in many cases it is not.

This is a question we are often asked:

Why should I pay for email when I can get Google Mail for Free?

There are many reasons for this; we usually don’t need to mention more than a couple before people understand the importance of paid versus free email.

Firstly, I believe that if you use email for business then it is not a good sign for your business if you use insecure free email to keep customer data. The fact that you can’t or won’t attempt to look professional and keep the basics, email, secure as possible, is a big indicator of other parts of your business where you may not have adequate standards and for many that mean potential clients will be put off. I personally will not use anyone who uses a free email address for any type of business. Using your own domain and email is not necessarily expensive and is no guarantee of anything, but it is the first hurdle and if you fail here it doesn’t matter that you have any awards for this and that and customer comments and reviews because I will not entertain the idea. This is shared by many people that I know. Remember that fraudsters generally don’t bother to use their own domain name as they need to keep costs down and be able to change at the drop of a hat, so they use free email. Most people who sign up to us with free email accounts were just fraudsters trying their luck with us, that is why we no longer accept free email account signups.

Even if you don’t use it for work or business then it’s better to have your own domain and email that you can control. Anyone can get a free email from Google and most fraudsters use Gmail or some other free email account to con people all the time, so you really will put some people off from even looking at you if your email address is a free account. I know that I will not entertain any business that uses them and one of the main reasons is below.

It is important to say that if you don’t care about your email and who is reading it then you may be able to use free email account such as Gmail. I have a Gmail account myself. I use it mostly for testing purposes, sending and receiving test emails from/to servers that I am testing so I can be sure that email is getting in to and out of our network correctly. The only thing that any one will find is test emails, so I am not concerned with who else reads it.

Why would you be concerned with who else reads your email?

Well, it surprises me just how many people don’t bother to read all of Googles various, complicated and hard to follow and sometimes hard to find terms of service and all the addendums that you agree to in order to use their services. Google does own some 50+ companies and is listed, at time of writing, as the third biggest company in the world by turnover, or at least its parent company Alphabet is. Do you think they are that big because of the free services? Well actually yes, they are in part. If you have the time to read all of their T’s and C’s then you will note the following:

(Concise version) – By using their services you give Google and anyone else they want, UNLIMITED LICENSE TO USE, MODIFY, RESELL, AND ANYTHING ELSE THEY WANT WITH ALL YOUR DATA. Yes every email you send or receive, they can use, including the attachments to do whatever they want with. If you send your latest play or movie script using or receive it in your Gmail account, you allow them to use it as they want. They can take your idea, change it and make the movie themselves. They don’t even need to change it as you gave them unrestricted license to do as they please.

You can read the full details here: https://policies.google.com/terms?gl=UK&hl=en but below is the extract verbatim that I refer to, I have underlined the interesting bit, they do their best to make it sound soft and cuddly but read it carefully:

When you upload, submit, store, send or receive content to or through our Services, you give Google (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content. The rights you grant in this license are for the limited purpose of operating, promoting, and improving our Services, and to develop new ones. This license continues even if you stop using our Services (for example, for a business listing you have added to Google Maps). Some Services may offer you ways to access and remove content that has been provided to that Service. Also, in some of our Services, there are terms or settings that narrow the scope of our use of the content submitted in those Services. Make sure you have the necessary rights to grant us this license for any content that you submit to our Services.

The last line is particularly important as you must have the rights to the content you are sending/receiving in order to be able to grant this license to others or you are in breach of the copyright of copyright holder who can sue you for breach of copyright because you sent it using Gmail.

This happened recently on another free service, Flickr, where a model had some pictures taken by a professional photographer, uploaded them to her account, but she didn’t realise that she did not hold the copyright to the pictures of herself but the photographer. As there is a similar granting of license to them as with Google as with all the other free services that I have looked at, she was promptly sued by the photographer.

This sort of thing is not new, Microsoft’s Hotmail used to have in it’s terms and conditions that anything you uploaded, sent or received actually belonged to them and not you at all. This was challenged and they backed down after some media attention and replaced it with you granting them an unlimited perpetual license to do as they please with it which is now used by everyone. Free just means you don’t pay up front, but they make their money out you. It’s better to retain control over how companies make money from your custom rather than letting them run freely to do whatever they like behind your back.

Also the new GDPR (or Data Protection Act 2018 in the UK) can cause a business using any free service a hassle. That is because you are required to keep personal data secure and you can’t do that if you send any personal data through a free email account as you grant the right to Google and anyone else they see fit to do with it they please, leaving you, not them responsible and quite likely in breach as you have effectively lost control of the data.

There are many other reasons to add to this discussion as well but I think there is enough to think about here.

CritchCorp Computers Ltd offers email accounts from as low as £1.50+vat per month. With cloud accounts you have many more features to help you secure your email, using encryption etc. Keep your business or home email safe by making sure you have control over your email.

We have just added a couple of new exciting TLDs to our shop so that you can now start to order your .PAGE and .APP domain names. These domain names are more secure because they require an SSL certificate in order to work in any modern browser.

Why will they not work without SSL?

Well these two TLDs have decided to put themselves in the HSTS pre-load list. This means that your browser will look at the TLD and recognise that it requires an SSL certificate to connect and will not connect if there is no valid SSL certificate in place. This makes it more secure as it cannot connect without it.

How is this different to the Google forcing SSL?

HSTS has been around since 2009 (then called STS) and is still going strong. It is used by high profile or high value sites to tell your browser that it they should only ever be connected to via HTTPS (secure) connections and never unencrypted (HTTP) connections. There are some other parameters which we will not cover here. This basically gives you protection from downgrade attacks where the attacker will downgrade your connection to your bank so that they can put themselves in the middle (a man in the middle attack) for which there is no way to know you are being attacked and they can have access to all your data, sessions and cookies. With the pre-load list your browser knows beforehand that a site should only be connected to over SSL and by adding these two TLDs to the list all websites ending in .PAGE and .APP will have to be connected to via HTTPS. Google is forcing everyone to use an SSL certificate but will not stop you from connecting; HSTS will prevent you from connecting. There is a lot more technical stuff but we won’t bore you with that right now. If you want the technical information then click here to read about it.

If you get your .PAGE or .APP domain name we can handle the technical side for you and get your new domain name connected and up and running in no time.

.PAGE and .APP domain names can be ordered in the normal way from here or your account.

Stay safe
