Start without signing up
Describe the purchase or add its documents immediately. You create the account after preparation, before authorising delivery, and all completed work is preserved.
- Describe the purchase, paste a table, or add files, images and links.
- Review line items, suppliers and the prepared request.
- Create or link the account before authorising delivery.
Organise projects and procurement files
A procurement file represents one comparison. A project groups files for an initiative; folders separate chapters, categories or departments.
PURCHASE ORGANISATION
Hierarchical structure and high-volume requests
The hierarchy prevents large bills of quantities from becoming one undifferentiated data set.
Large texts and documents are processed in durable blocks: Excel retains sheet and cell, PDF retains page ranges and Word retains its sections. Every completed block remains saved even if you close the page. Lots are then collapsible and the editor shows 50 items per page without losing the rest.
You can correct, split or merge items. Every change retains its source and lot relationship.
Discovery runs by lot and then consolidates duplicates and suppliers covering several lots. You review coverage for every lot.
AUTOPILOT
How Autopilot works
It automates repetitive work while preserving the buyer’s decision points.
It understands and structures the request, organises lots, starts supplier discovery and helps organise responses.
You can Pause, resume or take manual control. Status and history remain stored in the procurement file.
It stops for structure review, supplier review, approval of the exact email and the award decision.
Autopilot never sends email or awards by itself. Those actions always require an explicit human decision.
Information flow
Your request becomes structured line items; those items drive discovery and the authorised email. Replies and attachments populate the matrix. Agreements and allocations produce the decision and its documents.
Request→Items→Suppliers and email→Quotes and evidence→Decision and documents
STAGE 1 / 7
Request
Define clearly what the company needs to buy.
Title, written instructions, search territory and optional PDF, Word, Excel, CSV, TXT or images.
Keeps originals, checks file security and prepares the content for analysis.
Check the text and territory. Complete text works without an attachment; a file needs instructions.
Original request, files, location and timestamp.
A request ready for line-item extraction.
Main buttons
Next stage →- Save scope: stores where to search.
- Understand my request: analyses text and attachments.
- Autopilot: request a premium trial or start orchestration when enabled.
STAGE 2 / 7
Understanding
Turn documents and free text into comparable line items.
The request and its files.
Extracts products, quantities, units, specifications, terms and questions; organises chapters, sourcing events, lots and line items.
Search and edit any item, split or merge rows, and review collapsible groups. The screen displays 50 items per page without losing hidden items.
The complete hierarchy, structured line items and buyer corrections.
A confirmed requirement ready for supplier discovery by lot.
Main buttons
Next stage →- Save changes: stores every edit, including other pages.
- Split / merge: reorganises items without losing traceability.
- Confirm details: fixes the version used for discovery.
STAGE 3 / 7
Suppliers
Find and select suitable companies for each lot or category.
Confirmed items, lots, category and local, European or worldwide scope.
Runs a persistent search for each lot, verifies activity and contact evidence, removes duplicates and keeps results when you close the browser. When details are missing, it explains why and offers evidenced alternative searches.
Check coverage, location, evidence and contact for every lot. You can stop without losing results, provide requested details or choose another strategy.
Search state, candidates by lot, sources, diagnosis, answers, coverage and chosen suppliers.
An authorisable recipient list for resolved lots, with unresolved items clearly identified.
Main buttons
Next stage →- Find suppliers: starts a persistent search lasting up to three minutes.
- × Stop: ends the actual work and keeps progress.
- Continue: requires new details or a different strategy so an exhausted search is not repeated.
- Add supplier: includes a known company or contact.
STAGE 4 / 7
Authorise
Create the account at this point, preserve the work and review exactly what each supplier will receive.
Items, suppliers, signature, response deadline and expected documents.
Drafts a professional RFQ, builds the item table and prepares traceable HTML email.
First place the temporary purchase in Quick purchases or a project. Then edit subject, body, signature, recipients and attachments. Relevant changes invalidate prior approval.
Verified account, placement, approved version, signature, recipients and content fingerprint.
Sent requests with delivery confirmation.
Main buttons
Next stage →- Save draft and signature: stores reusable details.
- Regenerate proposal: creates another wording.
- Authorise and send: approves the visible version and sends it.
STAGE 5 / 7
Responses
Keep messages, quotations, files and clarifications in the procurement file. The sequence waits here until at least one quotation has been received and processed.
Supplier email replies and attachments.
Links each conversation, classifies status, extracts terms and drafts replies without sending autonomously. You do not need to keep the page open: when a reply arrives, you receive an email notification with a link to the file.
Check files, missing data and questions; edit or approve every proposed reply.
Messages, available headers, attachments, extractions and human decisions.
Quotations ready for comparison; stages 6 and 7 then become available.
Main buttons
Next stage →- Check for replies now: refreshes the status without leaving the file.
- Open conversation: shows the complete exchange.
- Send reply: sends only approved text.
- Record agreement: captures terms agreed outside email.
STAGE 6 / 7

Correct negotiated data, inspect sources and assess total commercial value.
Quotation versions, corrections, agreements and traceability.
A matrix ready for negotiation or award preparation.
Main buttons
Next stage →- Source / View file: opens the originating email, attachment and value.
