Specifications that keep everyone aligned — from contract to closeout

Scope creep starts when what's agreed isn't written down. Ressio specs give you a single, shared source of truth for every project requirement.

Specs organized by category — mirroring your estimate

Your specifications are structured the same way as your estimate — by category and item. Budget items sync automatically to your spec sheet, so you're not building the spec from scratch. Add descriptions, notes, and custom fields to capture exactly what was agreed for each scope item.

  • Spec structure mirrors your estimate categories automatically
  • Budget items sync to spec sheet — no double entry
  • Rich text descriptions for detailed specifications per item
  • Custom fields for item-specific notes and requirements

Share specs with clients and vendors — selectively

Control who sees what. Share specs with clients through the portal so they have a clear record of what's included in their project. Share with vendors through the vendor portal so subs are working from the current spec — not a printout from three months ago. Internal notes stay internal.

  • Share with clients via portal — they see the agreed scope
  • Share with vendors via vendor portal — subs work from the live spec
  • QR codes link directly to specific spec pages or sections
  • Private items remain internal — not visible to clients or subs

Specs that stay current — not a PDF from six months ago

When specs change, update them in Ressio. Everyone with access sees the current version — not an outdated PDF someone emailed in February. Changes tracked. History preserved. No more 'which version are we working from?'

  • Live spec sheet — always shows the current agreed scope
  • Changes to budget items sync back to spec automatically
  • Version history preserved for audit and dispute resolution
  • Replace a spec item and old version is retained in history

Attached files and photos — specs with visual reference

Attach product cut sheets, drawings, finish samples, and reference photos directly to spec items. When a sub needs to know the exact tile model number or cabinet spec, they find it in the spec — not in a text chain. Everything they need to execute is attached to the item it relates to.

  • Attach files and photos to individual spec items
  • Product cut sheets, drawings, and samples attached in context
  • Vendor-facing attachments visible in the vendor portal
  • Files accessible from any device including mobile

From estimate to signed spec in three steps

01

Build the spec from your estimate

Ressio syncs your budget items to the spec sheet automatically. Add descriptions, notes, and attachments to each item. Your spec is mostly built the moment your estimate is done.

02

Share with clients and subs

Control visibility per item and release the spec to clients via the portal and vendors via the vendor portal. Everyone sees the current scope — not a stale document.

03

Update as the job evolves

When scope changes, update the spec. Changes sync to the budget. History is preserved. Your record of what was agreed stays accurate from contract to closeout.

Specifications connected to your whole project

Ressio specs aren't a standalone document — they're connected to your estimate, selections, vendor portal, and client portal so the agreed scope travels through the whole job.

What builders say about specifications in Ressio

Before Ressio, specs lived in a Word doc that nobody kept updated. Now the spec is in the project and when something changes it changes there. My subs stop asking me what the current spec is.

Custom home builder, [City State]

The spec sheet connected to the estimate was the feature I didn't know I was missing. I document the scope once and it flows to the spec, to the client, and to the sub. No re-entering anything.

[Customer name]

Residential remodeler, [City State]

I had a scope dispute six months into a project. I pulled up the spec in Ressio — the agreed item, the date it was set, and the attachment showing exactly what was specified. The dispute was over in 10 minutes.
