Software Project SRS Template for SMEs

By Tushar ChoudharySRS • Software Development • SME • Project Planning • ERP • CRM

A practical software SRS template for SMEs covering roles, workflows, data, business rules, integrations, acceptance criteria, migration, and change control.

Software Project SRS Template for SMEs

A software requirements specification should turn business conversations into testable delivery rules. For an SME, the useful SRS is not the longest document. It is the document that defines who uses the system, what each workflow must do, which data matters, how exceptions work and how the business will accept the result.

This template is suitable for CRM, ERP-lite, inventory, booking, workflow automation, portals and internal tools. It can be used before requesting quotations or as the baseline after discovery. It is not a legal contract by itself, and regulated projects may require specialist security, privacy or compliance documents.

Editorial review: Reviewed on 3 August 2026 against VASUYASHII's current requirements and company-scoped business-software workflow. Use the companion editable requirement template to capture project-specific answers.

SRS Document Control

Start with a short control table so everyone knows which version is active.

FieldExample
ProjectDistributor order and inventory system
Document ownerOperations head
Business approverCompany owner
Delivery reviewerVendor project lead
Version0.4 draft
StatusUnder review
Last updated3 August 2026
Linked decision logProject decision register

Record material changes with date, author, reason and approver. Do not silently edit an approved SRS and then expect the quotation or timeline to remain unchanged.

1. Purpose and Business Outcome

Write the problem in operational language. Avoid “build a modern ERP.” A stronger statement is:

Sales staff currently confirm stock through calls, create orders in chat and re-enter accepted orders into billing software. The first release should give authorised staff current product availability, create an order request and let the office approve or reject it with a recorded reason.

Add two or three measurable outcomes such as reduced duplicate entry, complete status visibility or faster approval. These are target outcomes, not guaranteed ROI claims.

2. Scope and Explicit Exclusions

Separate included workflows from future ideas.

In scope example:

  • customer and product master;
  • sales order request;
  • stock availability view;
  • office approval;
  • order status history;
  • CSV export;
  • role-based access.

Out of scope example:

  • full accounting ledger;
  • e-invoice integration;
  • route optimisation;
  • customer mobile app;
  • payroll;
  • historical data cleanup beyond the approved import.

Exclusions prevent an early planning document from becoming an unlimited feature promise. Future modules can remain in a roadmap section without entering current acceptance.

3. Stakeholders and User Roles

Name the people who provide requirements, approve workflows, test the system and own production operations. Then define user roles.

RoleCan doCannot do
OwnerView all company reports and approve configurationAccess another company's data
Sales userView assigned customers and submit ordersChange purchase price or approve order
OperationsReview stock and approve orderManage platform-level settings
AccountantRecord payment and export invoice dataDelete product history
AdminManage users and mastersBypass audit rules without record

Permissions must be enforced by the backend. Hiding a button is not authorisation. Add branch, company or territory scope wherever data separation matters.

4. Current and Future Workflow

Document the current process before designing the future one. A simple table is enough.

StepCurrent methodProblemFuture rule
Receive orderWhatsApp messageMissing item detailsStructured order form
Check stockPhone callDelayed confirmationCurrent availability view
ApproveVerbalNo audit historyNamed approver and timestamp
BillManual re-entryDuplicate workApproved order available to billing
Follow upPersonal notesNo shared statusOwner and due-date queue

For each future workflow, identify trigger, actor, input, validations, decision points, output and failure path.

5. Functional Requirement Format

Give every requirement a stable ID and testable wording.

IDRequirementPriorityAcceptance evidence
ORD-01Sales user can create an order for an assigned customerMustValid order appears in pending queue
ORD-02Quantity cannot exceed configured rule without approvalMustSystem blocks and displays reason
ORD-03Approver can approve or reject with commentMustStatus history stores actor and time
ORD-04User can duplicate a previous order as draftCouldNew draft does not change original

Avoid words such as easy, seamless, robust or fast unless they are followed by an observable criterion.

6. Business Rules

Business rules often create more complexity than screens. Record calculations, approvals, status changes and constraints separately.

Examples:

  • only active products can be added to a new order;
  • GST rate comes from the product record but can be changed only by an authorised role;
  • cancelled documents remain visible in history;
  • payment cannot exceed the outstanding amount without a defined advance-payment flow;
  • each record belongs to one company;
  • an approved order cannot be edited; it must be revised or cancelled;
  • low-stock threshold is configured per product or category.

Include rounding, timezone, financial-year, unit-conversion and numbering rules where relevant. These details should stay consistent across UI, API, exports and PDF output.

7. Data Dictionary

Create a table for important records and fields.

EntityImportant fieldsValidationRelationship
CustomerName, phone, GSTIN, address, stateGSTIN format if providedHas many orders
ProductName, SKU, unit, GST, sale priceSKU unique within companyUsed in order items
OrderNumber, customer, status, datesCustomer requiredHas many items
Order itemProduct, quantity, rate, taxQuantity greater than zeroBelongs to order
UserName, login, role, statusUnique loginMember of company

State which fields are required, editable, derived, searchable, exportable and sensitive. Define archive or deletion behaviour before development.

8. Validation and Error Behaviour

Write what happens when data is incomplete or a service fails. Include:

  • field-level validation message;
  • duplicate record handling;
  • concurrent edit behaviour;
  • expired session;
  • network interruption;
  • integration timeout;
  • invalid import row;
  • partial bulk operation;
  • retry and rollback rule.

A useful requirement describes the recovery path. “Show an error” is incomplete if the user does not know whether to retry, correct data or contact an administrator.

9. Integrations

For every integration, document system owner, authentication, trigger, fields, response, retry and reconciliation.

IntegrationTriggerData sentFailure handlingReconciliation
Payment gatewayPayment attemptOrder ID and amountKeep pending, verify webhookDaily payment report
WhatsAppApproved documentPhone and secure linkLog provider failureMessage status queue
Existing CRMCustomer updateApproved customer fieldsRetry with idempotency keySync exception report

Provider fees, account ownership and sandbox access should appear in the project assumptions. See integration services for workflow-level planning.

10. Non-Functional Requirements

Non-functional requirements describe quality and operating constraints.

Performance

Name important workflows and test conditions. For example, “the product search should return an initial result within the agreed threshold for the approved test dataset and network profile.” Avoid promising an absolute speed for every device and connection.

Availability and recovery

Define backup frequency, retention, restore owner, acceptable recovery time and planned maintenance communication. A backup requirement is incomplete without a restore test.

Security

Define authentication, backend authorisation, password or OTP rules, session expiry, audit events, encryption in transit, secrets management and vulnerability handling. Use the OWASP Application Security Verification Standard as a reference when selecting controls; do not claim compliance unless it has been independently verified.

Accessibility and responsive behaviour

State supported viewports, keyboard needs, form labels, contrast, touch targets and error announcements. The W3C Web Content Accessibility Guidelines provide a shared reference.

Observability

Define logs, audit records, health checks, error monitoring and alert ownership. Avoid storing secrets or unnecessary personal data in logs.

11. Reports, Exports and Documents

Reports need source and calculation rules. Define filters, columns, totals, timezone, company scope and export format. A request for “sales report” is incomplete without these details.

This current VASUYASHII Business Suite screen illustrates report grouping in a multi-module system.

The screenshot demonstrates current product structure, not a standard SRS requirement for every project. Your document should list only reports needed for decisions or statutory workflows.

For PDFs, define template, numbering, company identity, tax fields, line items, totals, bank details, download access and regeneration behaviour.

12. Migration and Opening Data

Document the source files, owners, expected row counts, mandatory columns, duplicate rules and validation totals. Use a dry run before production import.

Acceptance may include:

  • all accepted rows imported;
  • rejected rows returned with reasons;
  • record counts reconciled;
  • opening stock or balance totals signed off;
  • sample records checked by business owners;
  • rollback copy retained for an agreed period.

Do not assume the developer will repair inconsistent historical data unless data-cleaning scope is written.

13. Acceptance Criteria and UAT

Assign each requirement to a test case. State the environment, test data, reviewer and evidence required. A UAT issue should include requirement ID, steps, expected result, actual result and severity.

Define release blockers. A spelling issue and a permission bypass should not have the same priority. Also define when an accepted requirement becomes a change request rather than a defect.

14. Deployment and Handover

Specify development, staging and production environments; account ownership; release steps; rollback; monitoring; documentation and training.

The handover register should include source repository, build instructions, API documentation, database backup, deployment access, third-party accounts, design source, open issues and support contacts. Never place live passwords inside the SRS.

Review the website delivery checklist for ownership principles that also apply to software systems.

15. Change Control

Use a simple change request containing:

  1. requested change and reason;
  2. affected requirement IDs;
  3. impact on workflow, data and integrations;
  4. cost and timeline impact;
  5. acceptance changes;
  6. approval or rejection;
  7. target release.

This protects both sides. It prevents informal chat messages from becoming invisible commitments and gives the business a record of why scope changed.

Traceability helps owners see whether a requested feature supports an outcome and whether it was tested.

Common SRS Mistakes

  • Writing only a feature list.
  • Copying enterprise templates with irrelevant sections.
  • Omitting current workflow and exceptions.
  • Leaving permissions to the UI designer.
  • Describing reports without calculation rules.
  • Calling every future idea “phase one.”
  • Using screenshots without written behaviour.
  • Forgetting migration and handover.
  • Approving subjective acceptance wording.
  • Editing the document without version history.

Owner Review Checklist

  • Is the business problem specific?
  • Are primary users and approvers named?
  • Does each workflow include exceptions?
  • Are scope and exclusions explicit?
  • Are business rules consistent across screens and reports?
  • Is data ownership clear?
  • Are integrations defined beyond provider names?
  • Can each requirement be tested?
  • Are migration and handover included?
  • Is change control agreed?

FAQs

Do SMEs need a formal SRS?

They need a shared, testable scope. It can be concise, but verbal requirements and scattered chat messages are risky when workflows, permissions or integrations matter.

Who should write the SRS?

The vendor can facilitate, but the business owner and process users must validate rules and acceptance. The final document should have named approvers from both sides.

Should an SRS include wireframes?

Wireframes help explain navigation and states, but they do not replace written rules, validation, permissions or acceptance criteria.

Can requirements change after approval?

Yes. Use change control to record impact on cost, timeline, data, tests and release. Keep the approved baseline visible.

Is the SRS the same as a contract?

No. The contract can reference the approved SRS for scope, while separately covering payment, ownership, confidentiality, liability and termination. Obtain legal review where needed.

How detailed should phase one be?

Detailed enough that users, workflows, data, business rules, integrations and acceptance are unambiguous. Future phases can remain at roadmap level until they are funded and approved.

Next Step

Complete the editable requirements template, review it with the people who perform the workflow, and then request comparable quotations. For help converting an operating process into a scoped SRS, contact VASUYASHII.
