Price the BOQ, buy materials against the customer's order and keep every company's books apart. ## In short 1flux is an ERP for contracting companies and facility services providers: fit-out, MEP contracting, maintenance and facility management. BOQs are priced as structured quotations, materials are bought against the customer's order through approved requisitions, and site deliveries are checked in before they reach the books. Each legal entity keeps its own currency, numbering, warehouses and ledger, in one workspace. The order-to-cash board moves only when real documents exist, from order request to payment completed.

Nobody dragged the card: each document moved it. The one flow ## How does an ERP for contracting companies run a job from BOQ to invoice? In 1flux the job’s quotation, sales order, material purchases, site deliveries and invoice sit on one record, each document starting from the one before it. Materials are bought against the customer’s order, so every purchase order is linked to the job it serves. Say a main contractor sends the BOQ for a third-floor fit-out. You price it as a quotation, attach the client’s LPO when it’s accepted and turn it into a sales order. A Customer demand requisition buys the materials against that order, and stores check the supplier’s delivery in before anything reaches the books. The goods receipt, the delivery note to site and the invoice each post their own journal. 1. Quotation (QT-2026-00412): Approved . Nothing posts. 2. Customer PO (Client LPO 3318) . Nothing posts. 3. Sales order (SO-2026-0302) . Nothing posts. 4. Requisition (Customer demand): Approved . Nothing posts. 5. Purchase order (PO-2026-0077) . Nothing posts. 6. GRN check-in (Checked by stores) .

Quotations ## Price the BOQ as a structured quotation A BOQ is a long, sectioned list, and 1flux quotations are built for it: a heading for each section, catalogue and custom lines, line discounts and availability per line, up to 500 lines. When the client’s RFQ arrives as a PDF or a photo, **Import PO with AI** drafts up to 200 lines from it and matches exact item codes to your catalogue. The formal cover letter carries Ref, To, Attn, Project and Subject, your terms and up to three signatories. Selling an annual maintenance contract (AMC)? Quote it as service lines on the same kind of quotation. - Approval rules by total amount, with sending blocked until approved - Numbered revisions (`/R1`, `/R2`) as the BOQ changes, each with a reason - Track each site, building or tender as a project in 1flux CRM, with scope tags such as Mechanical or Electrical [How 1flux quotations work](https://1flux.ai/products/quotations) A heading for each BOQ section, with supply and installation lines priced from the catalogue. Purchasing ## Buy materials against the customer's order In 1flux a requisition with the purpose **Customer demand (sales order)** has to name the sales order, and can copy its open lines.

The buyer awards the gate valve line to Saffar Valves Trading. The Award reason is required and is pre-filled with Lowest valid unit price, because this is the recommended offer. Receiving ## Check site deliveries in before they reach the books Receiving in 1flux is two checked steps. Stores record a [goods received note (GRN)](https://1flux.ai/glossary/goods-received-note) with the supplier, one or more POs, the delivery note number and a photo or scan, and choose **Checked & approved** or **Checked with comments**, which waits for an approver. Nothing posts yet. The goods receipt report then needs a reason for every short, over or rejected quantity, and posts stock and the journal in one step. Rejected goods go to their own register, to return to the supplier, scrap or hold. - Blind receiving, so stores count what really arrived - The purchase invoice is built from what was received, with a reason for any price difference [Goods receiving](https://1flux.ai/products/purchasing/goods-receiving) Stores check the delivery in; nothing posts.

[Talk to sales](https://1flux.ai/contact) ### Can 1flux buy materials against a specific customer order? Yes. A requisition in 1flux with the purpose Customer demand (sales order) must name the sales order it serves, and can copy the order's open lines. Once approved, it prints as a request for quotation for suppliers, and buyers compare offers and award each line with a reason. The link to the sales order follows the requisition onto every purchase order, so each purchase order records which job it's for. ### Can we price a BOQ in 1flux? Yes. You price a BOQ as a 1flux quotation, with a heading for each section, catalogue and custom lines, line discounts and availability per line, up to 500 lines. When the client's RFQ arrives as a PDF or a photo, Import PO with AI can draft up to 200 lines from it. The formal cover letter carries the project, subject, terms and up to three signatories. ### Can stores check site deliveries in before they reach the books? Yes. Receiving in 1flux is two steps. Stores record a goods received note (GRN) with the supplier, the purchase orders, the delivery note number and a photo or scan, as Checked & approved or Checked with comments, which waits for an approver. Nothing posts yet. The goods receipt report then needs a reason for every short, over or rejected quantity, and posts stock and the journal. ### Can we order materials before the supplier's price is agreed? Yes. A PO without price in 1flux lets you place the order now and agree the price later. Stores receive against it as usual, and the receipt carries a provisional cost until the buyer agrees prices. The Purchasing overview lists open orders waiting for prices under Needs action, and receipts still at provisional cost are flagged on the Inventory overview and aged in the cost audit. ### Can 1flux run several contracting companies in one place? Yes. 1flux runs several legal entities in one workspace, each with its own currency, registrations, letterhead, numbering, warehouses and books. Legal entities can be registered in the UAE, Saudi Arabia and India. You choose each person's entity access when you invite them, and a consolidation run combines every operating company into a consolidated trial balance in one group currency. ### Can facility management companies sell annual maintenance contracts in 1flux? Yes. Set up an annual maintenance contract (AMC) as a service item in your 1flux catalogue and quote it like any other line, with its own price, tax code and billing unit. Once the customer's PO is attached, the sales order lets you invoice service lines without a delivery note, in one invoice or several up to the quantity ordered, and receivables aging shows what's still due. ### Who approves what in 1flux? 1flux asks for approval at each point where money is committed. A quotation in a given amount band goes to any, all or a quorum of the approvers you name, and is sent only once they approve. A requisition is approved before it becomes an RFQ or a purchase order, and a GRN checked with comments waits for a back-office approver. Requesting, awarding, issuing, receiving and invoicing are separate permissions.
