What to Include in a POS Requirements Brief

Describe the business before the technology

An EPOS system combines the software and equipment used to record sales and support the till process. What that needs to look like depends on the business using it.

A single-counter cafe, a table-service restaurant and a leisure venue with reception may all take payments, but their working days are very different. Give suppliers enough context to understand yours.

Start with one short paragraph

Explain what you sell, how customers are served and where staff take orders or payments. Include the number of working positions you expect to need and anything important about how orders move through the business.

For example: “We operate a cafe where customers order at the counter and food is delivered to numbered tables. During busy periods, two members of staff may be taking orders. Drinks are prepared at the coffee station and cooked food is prepared in the kitchen.”

That paragraph gives a supplier much more to work with than “two tills required”.

“Describe the working day first. Let the supplier explain which technology they propose to support it.”

Turn feature requests into real service examples

Lists of feature names can create false confidence because two people may interpret the same phrase differently. “Kitchen integration”, “booking functionality” or “reporting” might mean something very specific to you and something else to the person preparing the quote.

Instead, describe an action and the result you need.

For a cafe

Rather than writing “kitchen ordering”, try: “A customer orders two coffees and two breakfasts at the counter for table 14. The appropriate preparation areas need the information required to make their part of the order, and staff need to know which customer or table the completed order belongs to.”

For a venue

Instead of “booking integration”, try: “A family arrives at reception with a booking reference. Reception needs to find the relevant reservation and follow our check-in process. Please explain what information your proposed setup can access and what staff would need to handle separately.”

Include the awkward second step

The first transaction is usually the easiest part of a demonstration. Add what happens next.

Hypothetical example: a customer orders breakfast and then changes one drink before it is prepared. Ask the supplier to demonstrate how the proposed setup handles that change, including what the person preparing the drink sees.

This moves the conversation away from whether a feature exists and towards whether the proposed workflow fits your service.

Separate essentials from future wishes

A requirements brief can quickly become a list of everything the business might conceivably want during the next five years. That makes quotations harder to understand and can distract from what needs to work on opening day.

Give each requirement a priority.

Essential

The business needs this for the proposed setup to work. For example: “Counter staff must be able to identify the table when taking an eat-in food order.”

Useful

This would improve the proposed workflow, but you want to understand the implications if it is not included.

Future

You do not need it now, but it could influence your choice. For example, you may intend to open another location later and want the supplier to explain what would be involved if that happens.

Do not ask a supplier to include a future requirement in the current solution unless that is genuinely what you want. Instead, ask them to describe how it could be approached later and identify any relevant dependencies or additional costs.

Use a requirements table suppliers can answer

The most useful part of an EPOS requirements brief can be a simple table. Give every supplier the same scenarios and ask them to respond in the same columns.

Delete rows that do not apply and add examples from your own operation. A short table of genuine requirements is more useful than a huge generic checklist copied from somebody else’s business.

Describe your existing systems and equipment

If you already use software or hardware that you hope to retain, include it in the brief. Do not simply write “existing printer” or “our booking system”. Give the product or model information where you can identify it.

If you take online orders, reservations or payments through other services, name the relevant products and explain what information, if any, you expect to move between them.

Ask for compatibility to be confirmed

Do not assume that equipment can be reused because the connector looks familiar, or that two software products work together because both are widely used. Ask the supplier to confirm what is compatible with the proposed setup.

Where a third-party connection is important, ask who provides each part, whether anything separate is required and which organization you would contact if information stopped moving as expected.

If the answer depends on another supplier, record that as something to verify rather than treating it as confirmed.

Ask exactly what the quotation includes

A headline total is difficult to compare if one proposal includes work that another leaves out. Ask suppliers to break down the elements relevant to their proposed solution.

Request a clear scope

Ask what equipment is included, what software or services are proposed, what installation or configuration work is included, what staff training is provided and what ongoing support arrangement applies.

Also ask what is not included. If additional equipment, third-party services, site work or other dependencies are required, you want to discover that while comparing proposals rather than during installation.

Describe the premises where it matters

Tell the supplier where equipment is intended to be used and anything relevant about the proposed working positions. Ask what information they need from you before confirming installation requirements.

Where networking, electrical work or other specialist work may be required, establish responsibilities and seek appropriately qualified advice rather than making assumptions from the quotation alone.

Use the brief during demonstrations

Once a supplier has responded, bring the same brief into the demonstration. This stops the meeting becoming a tour of impressive features that were never part of your original problem.

Ask staff to play themselves

Hypothetical example: your cafe manager normally takes an order, sends drinks for preparation, sends food to the kitchen and later deals with a customer changing one item. Ask the supplier to demonstrate that sequence using examples close to your menu.

Let the manager follow the process rather than having the salesperson perform every action quickly while explaining what would happen.

Test three versions of the transaction

For each important workflow, try:

The normal version: an ordinary sale or booking proceeds exactly as expected.

The changed version: the customer adds, removes or amends something at an appropriate point.

The problem version: ask what staff do when an expected device, connection or third-party service is unavailable.

Record unanswered questions beside the relevant requirement. “Supplier to confirm” is better than filling the gap with an assumption after the meeting.

Compare answers without changing the question

The biggest advantage of a written brief appears when quotations arrive. If every supplier received the same description, you can compare their answers against the same business needs.

Review requirement by requirement

For every essential item, record whether the proposed setup meets it as quoted, requires something additional, depends on another service or remains unconfirmed. Follow up ambiguous answers in writing.

Then compare the commercial scope: initial elements, ongoing elements, training, support arrangements and any third-party dependencies relevant to your setup.

Do a final team review

Bring together the people who will actually use the proposed system. Front-of-house may notice a slow customer step. Kitchen staff may spot unclear preparation information. A manager may care about the end-of-day process. The person comparing contracts may have questions about support or what happens when equipment needs attention.

The goal is not to write a technical specification worthy of an IT department. It is to remove avoidable assumptions before you buy.
