Ecommerce Software Requirements Guide
Write ecommerce software requirements as jobs and evidence — not a vendor feature dump.
Quick answer
Write ecommerce software requirements as jobs and evidence, not feature wishlists: primary shape, must-have workflows, volume unit, integrations, reporting cadence, and who updates the system weekly. Decision rule: every must-have must map to a weekly outcome and a plan tier you are willing to buy.
- Primary job statement
- Must-have workflows
- Volume / GMV / orders
- Integrations list
- Reporting cadence
- Roles & permissions
Key takeaways
- Separate must from nice — If the team still operates without it for 90 days, it is nice-to-have.
- Requirements own plan gates — Checkout, POS, or app must-haves imply a qualifying configuration — write that explicitly.
- One shape per sheet — Do not mix hosted platforms and sourcing apps on a single undifferentiated RFP.
1. Write three job statements

Example: Harbor Home (Shopify store, two people) needs checkout and refunds in one admin. A Spocket-class importer does not replace the platform; Square Online is a different job if POS is already the core.
Capture who merchandises, who refunds, and which ESP/ads tools must sync.
Common mistakes
Vendor feature grids as requirements
Start from your weekly outcome, then ask which plan unlocks it.
2. Split must-haves from nice-to-haves in writing
List day-one workflows for ecommerce software in two columns: must work before go-live vs can wait until adoption proves out. Must-haves drive plan gates and integrations; nice-to-haves belong on a phase-two sheet so demos do not inflate scope.
Worked example: Harbor People Ops marks SSO and audit logs as must-have, AI summaries as phase-two. Demos that skip the must column get cut from the shortlist early.
3. Map integrations and data boundaries
Name systems that must sync or stay out of scope: identity, payroll, CRM, ecommerce, chat, or data warehouse. For each integration, note whether it is native, API, or manual export — and who owns the connection when it breaks.
Worked example: Northline Finance requires HRIS sync to payroll and refuses tools that need nightly CSV babysitting unless IT signs off.
4. Get a one-page sign-off before trials
Share the must-have sheet with finance, IT, and the team lead who owns the weekly job. Trials should test the signed sheet — not a fresh wishlist from each demo.

5. Use a one-page checklist before demos
For Ecommerce Software Requirements Guide, list must-haves, owners, integrations, and the weekly ritual this purchase must improve. Share the sheet with finance and IT before you schedule a second demo.
- Name the primary job in one sentence.
- List must-have gates (plans, SSO, data residency, usage caps).
- Name integrations that must work on day one.
- Assign an admin owner and a weekly user champion.
- Define non-admin proof — what a sceptic completes without rescue.
Worked example: Harbor Ops refuses demos until the checklist is signed — cutting evaluation time in half.
6. Avoid the usual buying mistakes
Common failures in ecommerce: buying for brand familiarity, comparing entry tiles across different usage units, skipping a fair trial script, and adding scope before adoption proves out.
Run one trial script on every finalist the same week. Score on the same card. Write a one-paragraph decision memo that names what you are not buying yet.
7. Hand off to the category shortlist
When assumptions are frozen, continue on /best/ecommerce-software/ with the same headcount, usage band, and must-have gates on every quote.
