Simple spreadsheet tools are not the enemy. Most trading companies built the first years of their existence around them, and they worked. They are fast, flexible and excellent for calculations, analysis and working with data. The problem arises when you start expecting spreadsheets to also serve as the central system for sales, orders, inventory and invoicing. A growing company will sooner or later reach this point. The question, therefore, is not whether you use spreadsheets, but whether you use them for the right job.

Almost every trading company follows a similar path. At the beginning, one price-list workbook, a quote template in Word and a folder with invoices are enough. Spreadsheets are fast, accessible and everyone knows how to use them. As long as only a few people work with the same data, they work surprisingly well.

The turning point comes gradually. The company grows, more salespeople join, along with warehouse, purchasing and administration. Suddenly, more people are working with the same data, there are more orders, and information starts moving between emails, spreadsheets and different document versions. The spreadsheets still work – but the company is gradually expecting more from them than is practical to manage this way.

Below are five signs that you have reached this stage. They are not disasters. They are small inconveniences that people get used to – and that is exactly why they are dangerous.

1. There are multiple versions of the truth

The classic example: quote_Novak_final.xlsx, quote_Novak_final_v2.xlsx, quote_Novak_final_UPDATED.xlsx. Three files, three prices, and the one the customer actually received is probably a fourth – somewhere in an email attachment.

As long as one person works on the quote, it can be kept under control. Once a colleague covering during a holiday needs to access it, or a complaint arrives a year later, the search begins. And searching costs time that nobody invoices.

The same problem applies to price lists. If the price list exists in five copies on five laptops, five people may be working with different prices without anyone realizing it.

The issue is not that a spreadsheet tool cannot handle shared files or edit history. The problem arises when a company uses numerous separate files, copies and custom spreadsheets and needs to maintain one common source of up-to-date information.

A sign you are there: before working with a document, you first have to ask someone which version is the valid one.

2. A simple question does not have a quick answer

Try asking yourself these questions and measure how long it takes to get an answer:

• How much did we actually make on the order for company X?
• How many quotes did we issue last month, and how many turned into orders?
• Which quotes are more than three weeks old and have not been followed up?
• What is the average margin on goods from this supplier?

If the answer is „I would have to look that up“ and you then spend an hour searching for the right data across different spreadsheets and documents, your problem is not spreadsheets. Your problem is that the company does not have its data organized in a way that makes it easy to access.

Spreadsheets are an excellent tool for analyzing data. The problem starts when you want to use several spreadsheets at the same time to manage day-to-day sales. Instead of analyzing data, you end up looking for the right data.

And perception tends to be systematically more optimistic than reality – especially when it comes to margins, where it is easy to forget about delivery, installation or a discount a salesperson agreed to over the phone.

This connects with the topic we covered in our article about when it is better not to win a quote. You can only decide not to take on a job if you know what it will actually bring you.

3. The company depends on one person and their folder

In most trading companies, there is someone without whom sales simply grind to a halt. „They have it all in their head.“ They know which customer has which prices, what discounts have been agreed with suppliers and where those agreements are stored.

And that is exactly where the risk lies. When this person gets sick, goes on holiday or leaves the company, part of the company’s institutional memory goes with them. Not because they do not want to hand it over, but because it was never systematically recorded. It lived in their files, emails and head.

Knowledge that is not accessible to other people in the company eventually becomes a dependency on one particular person.

A sign you are there: when this person is away, certain types of quotes or orders simply have to wait.

4. You enter the same data four times

An enquiry arrives by email. It becomes a quote. The quote becomes an order. The order becomes a purchase order for the supplier, followed by a delivery note and finally an invoice. The same basic data appears in six documents – and someone repeatedly types or copies it.

Every such re-entry is an opportunity for an error. 100 becomes 1,000 units, an old price that has since changed, a swapped item. The error is often discovered – but only at the customer’s end or in accounting, which is the most expensive possible place for it to surface.

We looked at this process in detail in the article The Sales Process: From Customer Inquiry to a Paid Invoice. The principle is simple: data should enter the system once and then simply flow through the process. If people repeatedly enter it manually, you are paying them for work that software can do – and also for fixing the errors that result.

This topic will become even more important for another reason. With mandatory electronic invoicing coming in, having data in a structured format will become increasingly important. And that is significantly easier when the data is already in the system.

5. You promise delivery dates you cannot keep

A customer asks whether an item is in stock. The salesperson checks a spreadsheet but is not sure whether the information is up to date. So they call the warehouse to verify the stock level. In the meantime, part of the stock may already have been reserved or dispatched for another order.

As long as there are only a few such cases a day, they are handled with a phone call to the warehouse. As the company grows, the number of calls increases and salespeople start spending their time verifying information they should be able to access without having to ask someone else.

The same applies to supplier delivery dates. If you do not have information in one place about what has been ordered, when it is expected and which customer order it is intended for, you are planning blindly – and you may promise a customer a delivery date that later turns out to be unrealistic.

A sign you are there: before answering a customer, you have to call someone to verify what is actually true.

One sign does not mean anything yet

If you recognized yourself in one of these points, everything is probably fine. Your spreadsheets may still be doing exactly what you need them to do.

If you recognized yourself in three or more, the problem is probably no longer the spreadsheets themselves. It is that the company needs to connect multiple processes and multiple people are working with the same data.

Try to make a rough estimate. How many hours per week does your company spend searching for the right data, verifying information, re-entering data between documents and checking the current status of orders or inventory? Multiply that by the hourly rate.

The number you get is the cost of a way of working that may still function – but is already taking time away from customers and sales.

One system instead of dozens of spreadsheets

A growing company does not need another spreadsheet that solves one specific problem. It needs the different parts of its sales operations to connect with one another.

A quote can continue into an order. An order can lead to purchasing and inventory. Delivery notes can lead to invoices. And at every step, the data remains in one place.

That is the principle behind Offeris – an information system for trading companies that connects quotations, orders, invoicing, inventory management and sales cases in one system.

The advantage is not simply having fewer spreadsheets. What matters is that people across the company work with the same data and that individual processes are connected.

You can try Offeris free for 14 days with no commitment. You do not need to look for five different tools for five different tasks. Offeris connects quotations, orders, purchasing, inventory and invoicing in one system, so people across the company work with the same data and do not have to enter it repeatedly.
