Supplier management: purchase orders linked to the invoices that bill them.

Guliel is accounting and finance-operations software that runs invoicing, expenses, purchasing, payroll, reporting and a double-entry general ledger on one engine. Its supplier module keeps your supplier records, sends purchase orders, links each supplier invoice or bill to the order it bills, and tracks the order from sent to approved, invoiced and paid. When the supplier also uses Guliel, the two organisations are linked: the supplier sees your orders in its own account, approves them and creates its invoice from them.

The supplier, the purchase order, the supplier's invoice, the bill you approve and the ledger entry it posts are records in one data model. There is no separate payables app to keep in sync.

How the round trip works

1. Add the supplier

Invite a supplier by email, send it a link, or type its details. The record stays pending until the supplier accepts with its own Guliel organisation; registering is free. On acceptance, the placeholder record is replaced by a link to the supplier's real organisation. Guliel also adds an active supplier when a captured bill names a vendor it has not seen. Purchase orders go to active suppliers: those that accepted your invitation, and those created from bills.

2. Send the purchase order

Pick lines from your own catalog, from items a connected supplier publishes for outside orders (name, SKU and price, never its stock counts), or type them. Set the currency and an expected date. The order is numbered in sequence (ORD-2026-00001) and sent when you create it: by email to the supplier's address on file, and to a connected supplier's in-app notifications.

3. The supplier approves and invoices

A connected supplier opens the order in its own account and approves it, or rejects it with an optional note. From an approved order it creates its invoice in one step: a draft pre-filled with the order's lines, which it reviews and issues. The invoice is the supplier's document and follows the supplier's country format (invoices for 39 countries). Your order moves to invoiced, you get a notification, and the order page shows the invoice number, status and total.

4. The bill reaches your books

A purchase order is a commitment, so it never posts to the ledger. The cost posts when a supplier bill is approved. Bills come in through expense capture: scan or upload them, or let inbox capture (Gmail, Outlook, IMAP, POP3) pick them up. Guliel reads the vendor, amount and date and links the bill to the one open order that fits; the order moves to invoiced, or to paid when the document is a receipt. If no order fits, or several do, nothing is linked.

Either way, the bill waits for a person's approval (yours, a colleague's or your accountant's) before it posts to the double-entry ledger as a cost and a payable. A connected supplier's invoice shows on your order but does not enter your books by itself today; it still arrives as a bill. Native document exchange between Guliel organisations is planned.

5. Pay it

Guliel is not a payment processor. Pay the way you do now and record the payment against the document. When the invoice linked to an order is marked paid, the order moves to paid.

Two organisations, one relationship

Every business customer or supplier in Guliel is an organisation record, and your organisation keeps one relationship record per counterpart, flagged as customer, supplier or both. When a connected supplier invoices your order, Guliel adds you as a customer in the supplier's account, or reuses the record that already points at you. Access runs through organisation roles (manager, contributor, viewer). The supplier sees only the orders you send it; you see only the items it publishes. Linked suppliers are the first step of Guliel's business network.

Automations and AI

Three automation triggers concern suppliers: an order is created, an order is invoiced, and an item's stock falls below its threshold. An action can be any API operation or an outbound webhook, including creating a purchase order. Any AI client that supports the Model Context Protocol (Claude, ChatGPT, Copilot) can list suppliers and create orders through Guliel's MCP server, within the role and scopes the user grants.

Pricing

Per organisation, not per seat. The published Free plan is $0 a month with 200 invoices, 100 expense scans, 10 reports and 5 automations. Scanning a supplier's bill counts against your expense scans. Standard ($20) and Premium ($99) are published prices; billing is not live and paid plans are not on sale yet. See /pricing.

FAQ

Do suppliers need a Guliel account to receive purchase orders?

A supplier you add yourself must accept your invitation with its own Guliel organisation before it can receive orders; registering is free. Suppliers Guliel created from your captured bills are active without an account and get orders by email once an address is on file.

How is a supplier's bill matched to a purchase order?

By supplier name, amount and date: Guliel looks for one open order from that supplier whose amount fits the bill (allowing for tax), dated within 7 days. One match links the bill and moves the order forward; no match, or several, links nothing.

Does a purchase order post to the ledger?

No. A purchase order is a commitment. The cost posts to the double-entry ledger when a person approves the supplier's bill, and the payable clears when the payment is recorded.

Can a supplier invoice part of an order?

Not today. In the connected flow a supplier creates one invoice per approved order. Partial invoicing against one order and line-level quantity matching are not built.

Whose country rules apply to the supplier's invoice?

The supplier's. The invoice is issued from the supplier's organisation as a PDF in its country's format; the purchase order is your document. Structured e-invoice output such as Peppol BIS Billing is planned.

Can Guliel reorder from a supplier when stock runs low?

With an automation you build: the stock-below-threshold trigger can create a purchase order for the supplier and quantities you set, sent when it is created. Guliel does not store a preferred supplier per item. Reordering by an AI agent is planned.

Does a supplier that joins Guliel count as a seat on my plan?

No. Pricing is per organisation. A supplier that accepts your invitation runs its own organisation on its own plan.
