Migrating from Odoo 15 to Odoo 16: which OCA modules are available

Lets you define extra grouping rules for purchase orders when creating vendor bills, so orders are split into separate invoices based on fields you choose, in addition to vendor, company and currency.

Keeps a record of the expected arrival date that was promised when a purchase order was confirmed, so you can compare it with later changes and measure real supplier delays.

Adds a clock button on each purchase order line that opens a pop-up showing the last prices paid to the supplier for that product, and lets you apply one of those old prices to the current line.

Adds a discount column to the purchase price history wizard, so buyers can see the discount applied on each past purchase line and reuse it when selecting a historical price.

Adds a 'To Receive' column on purchase order lines showing how much quantity is still pending receipt. It is calculated automatically as ordered quantity minus already received quantity.

Adds a Brands filter to the product recommendation wizard in Purchase Orders, so buyers can narrow suggested products down to specific brands.

Adds classification filters to the purchase order product recommendation wizard, so buyers can suggest products based on their sales ABC classification and seasonality.

Adds a "Year of reference" option to the purchase product recommendation wizard, so Odoo can forecast next-period quantities by comparing the same period in a past year and applying the observed growth or decline.

Adds secondary unit columns to the product recommendation wizard in purchase orders, so buyers can order recommended products in a second unit of measure and see the quantity converted automatically.

Adds an Export button to the product recommendation wizard so users can download the recommended products for a supplier as an Excel (XLSX) file.

Adds a new tab on purchase orders that shows ordered, received and pending quantities grouped by product category, optionally split by unit of measure. Two settings let you control this grouping behaviour.

Adds a printable PDF report that groups the selected purchase orders by vendor, showing each vendor's orders and lines with a total per vendor.

Adds a 'Receipt Expectation' option on purchase orders that controls how incoming receipts are created when the order is approved. By default it uses the standard Odoo behaviour.

Adds a "Receipt Expectation" setting on vendor/partner records and automatically copies it onto new purchase orders when the vendor is selected.

Adds a "Manual" receipt expectation option on purchase orders and a wizard that lets stock users create a receipt (picking) by hand, choosing lines and quantities, with built-in checks before confirming.

This module lets you split a purchase order line into several lines when you manually record a receipt, so each received quantity is tracked separately. It also automatically merges quantities back if a receipt is cancelled.

Shows a receipt percentage on purchase orders and their lines, so buyers can quickly see how much of an order has actually been received.

When an incoming shipment is validated, Odoo automatically posts a message on the related purchase order listing the products and received quantities, and notifies the employees who follow that order.

Adds a reception status to each purchase order line (Nothing, Partially, Fully or Over Received) and uses it to compute the reception status of the whole purchase order, with an option to force a line as fully received.

When Odoo automatically creates a request for quotation from a stock rule, the Purchase Representative is set to the user who triggered the procurement instead of the system user.

Adds an analytic distribution field to purchase requests, used as the default for new request lines and copied to all lines when set.

Adds a confirmation step when cancelling a purchase request, asking the user to confirm and optionally provide a reason before the request is rejected.

Adds an Operating Unit to purchase requests and their lines, so each request belongs to a specific business unit. Users only see requests from the operating units they are allowed to access.

Adds a security group that lets selected users see and work on purchase requests from every operating unit, without having to assign those operating units to their user profile.

Adds sub-states to purchase requests, letting you track extra steps like 'To Verify' or 'Checked' inside the normal approval states and send an email when a request is verified.

Lets you turn purchase request lines into a purchase agreement (bid) directly from Odoo, either creating a new draft agreement or adding quantities to an existing one, and tracks the bid status back on the request.

When Odoo automatically creates purchase requisitions from stock rules, this module reuses an existing draft requisition for the same procurement group instead of creating a new one, adding the new lines to it.

Adds an Operating Unit to purchase requisitions (tenders) so each requisition and its lines belong to one operating unit, and only users with access to that unit can see them.

Adds a new agreement type option that lets purchase agreements (requisitions) automatically use only the remaining quantity when creating requests for quotation, avoiding ordering more than agreed.

Gives purchase quotations their own RFQ numbering sequence, separate from confirmed purchase orders. When a quotation is confirmed, its RFQ number is kept for reference and the order receives a new PO number.

When a purchase order uses a manually entered currency rate, this module makes sure that rate is also used for the stock moves created from that order, so the cost recorded in inventory matches the purchase order.

Keeps the operating unit consistent between purchase orders and the warehouse they deliver to, and copies it onto the resulting stock receipt. Users get automatic matching and a clear error if the two differ.

Link supplier return requests to the original purchase orders and see the purchase value of the goods being returned, including taxes and totals, on the return request and its printed report.

When a purchase order is confirmed, the secondary unit quantity entered on the purchase order line is copied onto the related stock moves, so warehouse staff see the same secondary unit figures on receipts.

Adds a second-level status (substate) to purchase orders and requests for quotation, so you can track extra steps like "Waiting for legal documents" or "In receipt" on top of the standard status.

Adds a 'Total Quantity' block to the purchase order form that shows the total ordered quantity, grouped by unit of measure and converted to each unit's reference unit.

Adds a Control menu under Purchase with two shortcuts: a list of incoming products you are waiting to receive, and a list of vendor bills. It restores the handy purchase control accesses that existed in Odoo v12.

Lets you pick a ready-made warning option on vendors and products, which automatically fills in the purchase warning message shown on purchase orders.

Create Work Acceptances directly from a purchase order's invoice plan, one installment at a time. The chosen installment controls the quantities proposed on the Work Acceptance instead of the invoice plan itself.

Adds late delivery fines to work acceptances: Odoo computes how many days late a receipt is, multiplies it by a daily rate, and lets you create a customer invoice or vendor refund for that amount.

Adds an approval workflow (tier validation) to Work Acceptances, so a Work Acceptance must be reviewed and approved by the right people before it can be accepted.

This glue module makes the refurbish and repair stock move features work together, so repair orders that produce a refurbished product also create and manage the related stock moves.

This module lets you scrap components or irreparable parts directly from a repair order. It adds a Scrap button on repair orders, a scrap counter, and links scrap records back to the repair.

This module links repair orders to lot restrictions on their stock moves, so the lot set on a repair order is automatically applied to the related stock move. It helps avoid reserving the wrong lot during repair operations.

This module links repair types with repair security groups, giving repair users read-only access to repair types and repair managers full access. It installs automatically when both repair_type and repair_security are present.

Adds a read-only reporting screen that counts hotel reservations grouped by reservation number and status, shown as a pivot, graph or list. Users find it under Hotel Management > Reports > States By Reservation.

Adds a read-only reporting screen that groups restaurant reservations by their status, so you can see how many reservations are in each state and analyse them in list, graph or pivot views.

Adds a "Journal items" smart button on the contact/partner form that opens the list of accounting journal items linked to that partner.

When enabled, cancelling a sale order also cancels its posted but unpaid invoices. The option is turned on per company in the Sales settings.

Lets you add a traffic-light status (green, yellow or red) to commission rules, so the same product can earn different commission percentages depending on the semaphore shown on the invoice line.

Automatically re-applies promotion programs marked as auto-apply on sales orders whenever the order or its lines change, without the user having to click anything.

Lets you use multi-product promotion criteria (from the coupon_criteria_multi_product module) when applying coupons and promotions on sale orders. Odoo checks each order's products and quantities against those criteria before granting the reward.

Adds an extra condition to coupon and promotion programs so they only apply to sales orders that match a chosen order filter, for example a specific sales team or customer.

Keeps automatic coupon and free-shipping behaviour working together on sales orders: when a delivery line is added automatically, coupons are still applied, and when coupons are recomputed, delivery lines are not refreshed again.

This module lets you create coupon programs that give free products based on a product domain, automatically adding 100% discounted reward lines to sales orders when the domain conditions are met.

Lets you apply a coupon promotion discount only to the products that match a product domain, instead of the whole order. It also supports a strict per-product limit so each product must individually meet the minimum quantity and amount rules.

Prevents reward coupons from being emailed to customers when their sales order exceeds the allowed financial risk. It links coupon promotions with credit risk checks on confirmation.

Lets you mark promotions as incompatible so that two conflicting promotions cannot be applied to the same sales order. When a customer tries to add a promotion or coupon that clashes with one already on the order, Odoo blocks it with an error message.

Limit how many times a promotion or coupon can be used per customer or per salesperson. When a limit is reached, Odoo blocks the promotion and shows an error message.

This module lets you set up promotions that give several different free products as a reward on a sales order. When a promotion with multiple gift rewards applies, Odoo automatically adds the free products as separate order lines with a 100% discount.
