A good software specification decides the fate of a tender before it even starts. This guide brings together, in plain language, the sections a solid request for proposal (RFP) needs, the mistakes made most often and a downloadable sample template, for IT managers (CIOs), purchasing teams and the owners who make the decision. The aim is not to sell you anything; it is to help you receive the right proposal, at the right price, in a form you can actually compare.

The specification is the only document that translates your requirement into the supplier's language. The clearer it is, the more comparable the proposals you receive.
A software specification, commonly called an RFP (Request for Proposal), is the document that explains a project's scope, expectations and evaluation criteria to every supplier in the same language. Without one, the proposals you receive are built on different assumptions: one includes training, another does not; one covers data migration, another invoices it later as an extra line. What you are left with is a table comparing apples with pears.
A clear specification does three things at once. First, it disciplines your own request; writing down your requirement shows you the points you had not thought through. Second, it forces suppliers to quote against the same scope, so prices become genuinely comparable. Third, it heads off the "that was not in scope" arguments that surface at contract stage and during delivery.
It is only fair to say the opposite as well: an excessively rigid specification that describes every screen pixel by pixel also makes the work harder. An over-detailed document can prevent a supplier proposing a better solution and it inflates the price. The right balance is to write "what you want" precisely and leave "how it will be done" to the supplier's expertise. This guide is meant to help you strike that balance.
The ten sections below let you gather both off-the-shelf and custom software proposals within the same framework. Shorten or extend each one to suit your own project.
Most of these mistakes cost money not when the proposals arrive but in the middle of the project. Read this list once more before you send the specification out.
Instead of writing "there should be this button on that screen", write "this task should reach this outcome". Defining the requirement in terms of outcomes gives the supplier room to propose a better and cheaper route.
The sentence "it will integrate with our existing systems" means nothing on its own. Which system, in which direction, which data, how often? A vague integration clause is the single biggest source of price variance between proposals.
Moving legacy data is often a project in its own right. If its volume, quality and cleansing needs are not written down, suppliers either quote too low for nothing or cautiously high. Both mislead you.
Go-live is not the end of the project but the beginning. If the warranty period, support hours and response times are not written down, expectation and proposal collide at the first fault. Settling the SLA up front is the cheapest insurance there is.
Asking for one total makes comparison impossible. Ask for setup, licences, migration, training and maintenance separately. When one proposal looks cheap, it is usually because the maintenance or migration line has been hidden.
Insisting on a particular brand, technology or architecture shuts down competition and can tie you to a single supplier. Unless it is genuinely mandatory, describe the outcome and let the supplier propose the technology with its reasoning.
Building on the headings above, we have prepared a 12-section skeleton you can fill in; company details and evaluation criteria have sections of their own. Adapt it to your own project and send it straight to suppliers.
The sample template we have prepared has 12 sections: company and project details, project objectives, current situation, functional requirements, integration requirements, technical requirements, data migration, training and go-live, maintenance/support/SLA, what we ask of suppliers, pricing format and evaluation criteria. In the functional requirements table, each feature's priority is marked as must-have, nice-to-have or later (Z, O and İ in the template); the pricing format section contains a table that separates one-off items from annually recurring ones. Most sections are simply blanks to fill in; the objectives, requirements, pricing and evaluation sections carry short guidance notes.
You can download the template at /sablonlar/yazilim-sartnamesi-sablonu.md. It is currently in Turkish; because it is plain text (Markdown), it opens in any editor, copies easily and converts readily into your own corporate template.
One practical tip when using the template: keep the "must-have" features limited at first. If you mark every wish as a must-have, both the price and the timeline swell. Mark only the genuine essentials as must-have (Z) and the rest as nice-to-have (O) or later (İ); that distinction is what allows suppliers to give comparable, realistic proposals.
We are open about how we read a specification when one reaches us and how our proposal answers each section. In fairness, this should be said first: if your scope is standard and settled, an off-the-shelf product is usually faster and more cost-effective; if your processes are distinctive and do not fit the available packages, custom software is the better answer. Pan makes that decision with you, and then builds the bridge.
You can, but the proposals you receive will most likely not be comparable. Without a specification, every supplier quotes on its own assumptions: one includes training and data migration, another does not. The proposal that looks cheapest can turn out to be the most expensive once the hidden items appear. For very small, clearly defined jobs a short requirements list may be enough; but if you are going to compare several suppliers, we recommend putting at least the scope, integration, data migration and pricing format sections in writing.
Detailed enough to make clear what you want, yet flexible enough not to stop the supplier proposing something better. Good practice is to describe the outcome precisely (which task should produce which result) and leave the technical detail of the solution (which architecture, which technology) to the supplier to propose with its reasoning. Specifications that describe every screen pixel by pixel shut down competition and creativity and push the price up. Splitting the feature list into mandatory, preferred and optional is the easiest way to find the right level of detail.
Yes, but in proportion. A small company's specification does not have to run to dozens of pages; a clear two- or three-page document is usually enough. What matters is getting the sections right: what you want (scope), what it must connect to (integration), the state of your existing data (migration), your training and maintenance expectations, and an itemised pricing format. Even those five sections go a long way towards sparing a small business the later surprise of "wasn't that included?"
The three belong to different stages of procurement. An RFI (Request for Information) is for gathering information; it is used to get to know the market and the suppliers. An RFP (Request for Proposal) is the tender specification this guide is about; you ask suppliers to propose a solution to your requirement and to price it. An RFQ (Request for Quotation) is a request for price alone, once the scope is fully settled. In software projects the RFP is usually the right instrument, because the approach to the solution matters as much as the price.
Ask for it itemised. A single total makes proposals almost impossible to compare. Asking for setup/development, licences, data migration, integration, training and annual maintenance as separate lines both brings hidden items to the surface and shows you where each proposal is expensive. It is well known in the market that non-licence items (setup, migration, training, maintenance) can account for a significant share of the total investment; that is why seeing these lines separately is critical to your budget planning.
Not unless you have a compelling reason. Mandating a specific database, programming language or brand narrows competition and can leave you dependent on a single supplier. If there are concrete reasons such as compatibility with your existing systems, the skills of your in-house team or a legal obligation, state them by all means; otherwise, describing the outcome and leaving the technology choice to the supplier to propose, with its reasoning, generally produces healthier and more competitive proposals.
A software technical specification is written by describing the need in terms of outcomes under these headings: scope and objectives, the module and feature list, integration requirements, technology and architecture expectations, data migration, training and roll-out, maintenance and SLA, references and team, the price format and the timeline. Splitting features into must-have, nice-to-have and later lets suppliers give comparable, realistic proposals.
Yes. The software specification template prepared by Pan Innovation House has 12 sections: company and project details, project objectives, current situation, functional requirements, integration, technical requirements, data migration, training and roll-out, maintenance and SLA, what is required of the supplier, the price format and evaluation criteria. In the requirements table every feature is prioritised as must-have, nice-to-have or later (Z, O and İ in the template). The template is currently in Turkish; it is a plain-text (Markdown) file that can be downloaded from www.paninnovation.com/sablonlar/yazilim-sartnamesi-sablonu.md, opens in any editor and is easy to turn into your own template.
Send us the specification you have prepared and we will give you a proposal that answers every section openly, priced item by item. If you do not have a specification yet, we can start from the sample template and clarify your requirement together. No sales pressure, just a conversation to help you make the right decision.
